John Torous specializes in treating psychosis. So when he started reading about “AI psychosis” in the news, he expected to see a wave of patients in his clinic.
But the wave never came.
“It’s always interesting when things you’re reading about don’t match what you’re seeing on the ground,” said Torous, a Harvard Medical School associate professor of psychiatry at Beth Israel Deaconess Medical Center and the director of BIDMC’s Digital Psychiatry division. “We are seeing in the popular press that people are worried about AI psychosis, but what we’re seeing in emergency departments and outpatient clinics seems very different.”
Torous is a co-author of a viewpoint paper in The Lancet that proposes a functional typology of psychotic phenomena associated with large language models. He and co-authors Matthew Flathers, a BIDMC-affiliated computer scientist, and Spencer Roux, a member of Harvard’s Digital Patient Advisory Board, suggest that AI psychosis — which is not a formal diagnosis but a media label — can actually refer to several distinct phenomena.
Torous and his co-authors created their typology based on AI’s rolein a patient’s delusions as either the catalyst, the amplifier, the co-author, or the object.
As a co-author who has worked to incorporate the patient perspective, Roux emphasized that psychosis is treatable and that support networks should focus on understanding underlying causes and providing structured support. “You have to have hope that people in treatment can get better,” Roux said.
In this edited interview, Torous outlined how researchers are beginning to make sense of AI-associated psychotic phenomena.
You write that previous generations of new technology, like radio and TV, were also implicated in psychosis. How is AI similar, and how is it different?
It’s not uncommon that people have delusions about the radio or TV talking to them, and no one would reasonably say that the radio or television causes people to be psychotic, right? I can convincingly tell someone that the TV is not talking to them; it’s a one-way medium.
What makes AI trickier is that AI really does talk to you, and it feels very real. AI can validate unreasonable thoughts through sycophancy, express romantic or sexual attractions, and trap people in conversations that can last for days and sometimes weeks, if not months. Real risks for chatbot harms are long conversations (think thousands of messages), ascribing sentience to the chatbot, and perhaps interacting with it via voice instead of text. Risk does not mean there will be harm, but from various public reports, these risk factors are often present when there is harm.
What do you make of media reports of AI psychosis?
I would caution against drawing too many conclusions from those reports. They may be missing medical context, such as a family history of delusions or schizophrenia, or other factors. Even in cases where it does seem that AI is the catalyst for new psychotic symptoms, we often see people overusing AI, staying up all night, isolating socially — things that aren’t good for anyone’s mental health, and that can certainly push people into psychosis if they have a genetic predisposition for it.
“What makes AI trickier is that AI really does talk to you, and it feels very real.”
What’s happening is that any time AI is involved at all, it gets labeled AI psychosis. That makes it harder to really understand what’s happening — and for the people for whom AI-induced psychosis may be real, their stories are getting drowned out by other things. We really do need to figure out if young people, vulnerable people, are at risk of AI-induced psychosis, but until we know what the term really means, we can’t even begin to understand what’s happening.
Let’s talk about the four roles you defined in your typology.
In the catalyst role, the LLM triggers psychotic symptoms in a person who had no previous history of psychotic illness. This would be the classic or truest form of AI psychosis, and it certainly could happen, but it’s very hard to prove, especially just from media reports.
In the amplifier role, the LLM exacerbates existing psychiatric symptoms in patients who have a documented history of psychosis or delusions.
When it’s a co-author, the LLM encourages the user to take risky actions through narratives that evolve over time. For example, there was a 2021 case of a British teen who breached Windsor Castle intending to kill the queen. Court records later showed that an LLM had reinforced his statement that he was an assassin and bolstered his taking his plan from idea to action.
When it’s in the object role, the LLM becomes the focus of a delusional belief system. Someone may attribute sentience to it. Or they might project beliefs onto it about consciousness, persecution, or transcendence.
How do you hope this work helps clinicians?
There’s a general consensus in my field that we’re just not seeing people come to the hospital saying, “AI caused this.” I feel comfortable saying that AI as a catalyst of psychosis is very rare.
It seems more common that AI is the co-author or the object or the amplifier of existing delusions. But again, our terminology is messy here.
Imagine a person who is developing schizophrenia. They are in a state of heightened suspicion and begin to express beliefs that the chatbot has supernatural powers. In this case, the chatbot is the object of their LLM-associated psychotic phenomena. Even if we take the chatbot away, the person is likely to continue to develop schizophrenia.
Now let’s assume the patient already has an established diagnosis of a mental illness and they’re managing it well. Then they start to use a chatbot, and it keeps them awake all night with an ongoing fake romance. They begin to sleep less and socially isolate. Now the chatbot is more in an amplifier role.
If there were a case where a person was not likely to develop the illness, began to use a chatbot, and did show signs of it, that would be the catalyst role. In short, I’d like for us to get to a place where we’re not asking, “Is this AI psychosis or not?” but instead we’re asking, “Is the AI the catalyst here, or is it not?”

Exhibit traces University’s role in America’s birth — from campus barracks to Founding Father alumni
Minutes from a 1775 Harvard faculty meeting describe a commotion caused by students protesting the drinking of India tea at breakfast, a not-too-distant echo of the Boston Tea Party of 1773. An official document asks for financial reparations, listing damages to the College caused by the Continental Army’s military occupation. A page from a 1766 annotated almanac used by Harvard math and philosophy professor John Winthrop and his wife, Hannah, notes the “glorious news” that the “horrid Stamp Act” had been repealed.
These documents are part of the exhibit “Harvard and the American Revolution,” which explores the University’s participation in the nation’s struggle for independence. Launched to commemorate the 250th anniversary of the Declaration of Independence, the exhibit displaying objects, letters, and official documents from the Harvard University Archives is on view at the Pusey Library through Dec. 18 and available digitally.
“What we have here is Harvard’s history,” said Sarah Martin, associate University archivist for community engagement at Harvard University Archives. “From our collection, we are able to look at exactly what students and administrators at the time were going through during this incredible moment of upheaval and change. The exhibit looks at the past and what happened even before the Revolution, what happened during the war, and how this moment in time continued to influence and inspire this campus today.”
The exhibit begins with the years 1760-1775, during which Harvard became a center of new ideas that fostered the seeds of revolution against Great Britain. Many of its graduates joined the revolutionary movement, among them Samuel Adams (A.B. 1740, A.M. 1743) and John Hancock (A.B. 1754), who would lead the Sons of Liberty to oppose British rule in the colonies. The display includes a broadside from 1758 that mentions John Adams (A.B. 1755), whose master’s thesis address in 1758 spoke on the necessity of a civil government.

By the time the “shot heard round the world” in the April 1775 Battles of Lexington and Concord marked the official start of the Revolutionary War, Harvard was involved in the independence effort. By May, Gen. George Washington’s Continental Army arrived in Cambridge and occupied campus as military encampments. During his stay in Cambridge, Washington lived at Wadsworth House, the residence of Harvard’s president, as well as at Longfellow House.
The Continental Army occupied Hollis Hall, Massachusetts Hall, and Harvard Hall, among other buildings, as barracks and military offices. Harvard students were evacuated and moved to Concord. Documents from the era demonstrate the impact of the war on students, faculty, and administrators. The exhibit displays Winthrop’s almanac, in which he and his wife noted the Battles of Lexington and Concord, their move to Concord, the Battle of Bunker Hill, and a meeting with Washington.
A letter written by Harvard tutor Caleb Gannett (A.B. 1763, A.M. 1766) to Professor Edward Wigglesworth asks for help when his return to Cambridge was upended by the Siege of Boston. Dated May 2, 1775, the letter reads, “I am told that all business is at an End at the College — that the Buildings are occupied for Barracks … am anxious about the things I left in my Chamber — hope such care has been taken care of them as that they are safe.”
The exhibit ends with a reflection on the years after the Revolution. Eight Harvard graduates signed the Declaration of Independence: John and Samuel Adams, Hancock, Elbridge Gerry (A.B. 1762, A.M. 1765), Robert Treat Paine (A.B. 1749), William Ellery (A.B. 1747), William Williams (A.B. 1751), and William Hooper (A.B. 1760).
A second part of the display highlights buildings that were used during the Revolutionary War that are still standing. More than 1,500 soldiers occupied the University grounds, including Massachusetts Hall, Hollis Hall, and Holden Chapel, between April 1775 and March 1776 during the Boston siege. A walking tour connecting all those buildings is in the works, said Martin.
“What I’m hopeful can be taken away is the connection from the past to the present,” said Martin. “What we’re hoping people, including students, will do is walk in these Revolutionary footsteps as they walk around campus. We hope that it gives folks some connection to what they’re seeing outside, but also to understand the history underneath their feet.”
Hearing breakthrough holds upGene therapy yields lasting gains for patients with inherited deafness: ‘How well it worked is really amazing.’
Gene therapy yields lasting gains for patients with inherited deafness: ‘How well it worked is really amazing.’

An experimental gene therapy for people with an inherited form of deafness led to durable hearing improvements, a new study shows, with associated gains in patients’ ability to recognize speech.
The research corrected mutations in the OTOF gene, one of about 200 genes whose mutations are known to cause deafness from birth. Patients 18 and younger saw the strongest gains in hearing and ability to recognize speech. Adults receiving the therapy also saw improvements, though the effect was smaller. Overall, 90 percent of recipients saw their hearing improve, with half reaching normal levels by the study’s end at 2½ years.
“How well it worked is really amazing,” said Zheng-Yi Chen, co-senior author of the findings and a Harvard Medical School associate professor of otolaryngology-head and neck surgery at Mass Eye and Ear. “After 2½ years, more than half of them reached a normal level. They can hear a whisper. At that level, it’s better than mine.”
Worldwide, about 430 million people are affected by hearing loss serious enough to require rehabilitation, including 34 million children, according to the World Health Organization. Sixty percent of deafness in newborns has genetic causes, with mutation in the OTOF gene responsible for between 2 percent and 8 percent of cases. Babies with the OTOF mutation are completely deaf at birth, which affects speech acquisition and can hinder cognitive development.
Though the OTOF gene mutation is responsible for a relatively small proportion of inherited deafness, researchers said the platform developed in this work can be modified to correct other genes implicated in deafness. In fact, Chen said, the research team is already at work modifying the platform so they can treat deafness due to mutations in the GJB2 gene, the most common cause of genetic hearing loss.
The work, published April 22 in Nature, was conducted by researchers at Mass Eye and Ear, Harvard Medical School, and Fudan University, with additional trial sites in China. It builds on research published in 2024 that piloted the therapy among a small number of children. Those trials resulted in improvements rapid enough to surprise researchers and thrill parents, who saw their children go from completely deaf to responding to voices within just weeks.
“As follow-up time goes on, these children continue to bring us ongoing surprises,” said Yilai Shu, co-senior author of the study, whose team at Fudan University’s Eye and ENT Hospital led the study’s clinical work. “They progress from responding to sounds, to imitating speech, to speaking in short sentences, then to reciting poems and even singing. They always fill us with joy and encouragement.”
The therapy targets a condition called DFNB9, caused by the OTOF mutation. OTOF encodes the otoferlin protein, active in a snail-shaped structure in the inner ear called the cochlea. There, sound waves are translated into electric signals that, with the help of otoferlin, are conveyed to nerves and the brain. Without properly functioning otoferlin, electric pulses generated in the ear never make it to the brain.
Researchers said DFNB9 was an attractive target for therapy because it is caused by a mutation in a single gene, simplifying the repair. In addition, though the mutation disrupts signaling between the ear and the brain, cochlear cells are undamaged and ready to perform once the connection is restored.
To treat the condition, researchers injected a neutralized virus carrying a normal copy of OTOF into the fluid of the inner ear. The virus travels to the cochlea and expresses the OTOF gene in cochlear hair cells. That jump-starts production of normal otoferlin and restores the connection between the cochlea and nerves leading to the brain.
The study involved 42 participants carrying the OTOF mutation and ranging in age from nine months to 32 years. They were treated at eight trial centers across China.
Among those who responded to treatment, some reported hearing sound in as little as two weeks. Improvement was rapid over the first six weeks, plateauing around 26 weeks, with hearing recovery maintained through 2½ years. Though half achieved normal levels of hearing by that point, many of those who didn’t nonetheless saw significant improvement, Chen said, though hearing aids or other assistance might be required for day-to-day functioning.
That the effect endured so long was important, Chen said, because early lab experiments in mice saw the effect fade over time. Another key finding, he said, was that the treatment is safe, causing no serious adverse events among participants and no dose-related toxicity among groups that received three different doses.
While research will continue, Chen said that the team, whose work is supported by the Chinese and Shanghai governments and Fudan University, is beginning to explore regulatory requirements for the treatment to be approved for use in the clinic. That effort will begin in China. The hope is that expansion to other countries, including the U.S., will follow.
“The success of OTOF gene therapy marks a paradigm shift in treating hearing loss,” said Shu, a former postdoctoral fellow in Chen’s lab. “Going forward, personalized gene therapy approaches can be developed for congenital deafness caused by different gene mutations. These strategies will undergo preclinical efficacy and safety assessments to support their clinical translation.”
The scientists will continue to follow study participants through five years, said Chen, who also holds the Ines and Fredrick Yeatts Chair in Otolaryngology at Mass Eye and Ear. Several outstanding questions remain, including why 10 percent of participants didn’t respond to treatment, and why adults didn’t respond as well as youth.
“We have been working in this field for decades and there was nothing, nothing, nothing,” Chen said. “Then the treatment came out, worked really well, and now more trials are coming, some of which will be very successful. We’re looking forward to what the future will bring for patients.”
Not your father’s Wild, Wild WestMegan Kate Nelson’s new book challenges myths of American frontier, finds more diverse, complex saga
Megan Kate Nelson’s new book challenges myths of American frontier, finds more diverse, complex saga

Megan Kate Nelson has often been surprised by the misconceptions people have about the West.
Raised in Littleton, Colorado, in a family of avid road-trippers, she had visited 45 states by the time she started at the College in 1990. Nelson said classmates (who’d presumably spent less of their summers in the family car) would ask, “Did you ride your horse to school?” “I grew up in the suburbs!” she’d say. “No, I didn’t ride my horse to school.”
And those students weren’t alone. Nelson ’94 came to understand over decades of historical research how incorrect the founding myth of westward expansion was: that white men single-handedly brought American ideals to the undeveloped frontier along the Oregon and Santa Fe Trails and shaped the West.
In her new book, “The Westerners: Mythmaking and Belonging on the American Frontier” (Scribner), the Pulitzer Prize-finalist historian puts forth a sprawling, interwoven saga through the stories of diverse, dynamic individuals who traveled and settled west of the Mississippi as the U.S. expanded its boundaries and influence in the 19th century.
Nelson’s story runs through seven protagonists, whose paths intersect as they criss-cross American territory, and sometimes beyond it.
Some characters will be familiar to readers, like Sacagawea, the Indigenous woman who helped lead Meriwether Lewis and William Clark’s expedition through the Louisiana Territory. Others, like Maria Gertrudis Barceló, a prominent Sonora-born saloon owner in Santa Fe, are lesser-known.
Nelson expands the stories of even characters like Sacagawea, whose life is often described in the context of a single American expedition.
“This was an extraordinary moment in her life,” said Nelson in an interview, “but it was only one moment.”
“We think of the West as such an enormous region, and it is, but in the 19th century, the population was relatively small, and the chances that people would run into each other, or had heard of one another, were pretty good.”
Before meeting Lewis and Clark, she had traveled a great deal of the American West — born in Shoshone lands in the northern Rocky Mountains, stolen by another tribe, and brought to the Upper Missouri Valley.
Years after the expedition, she put her 6-year-old son, Jean Baptiste Charbonneau, under the care of Clark, which she believed could help create bonds between the Hidatsa people of Knife River and Americans in St. Louis.
Her son would become a prominent figure in the West, encountering people like Virginia native Jim Beckwourth, a fur trader, scout, and entrepreneur who serves as the connective tissue between many of the book’s protagonists.
Nelson said she’s heard Beckwourth referred to as the “Forrest Gump of the 19th century,” a description that seems apt given Beckwourth’s frequent and varied appearances at important moments in the history.
Born to an enslaver father, he migrates West, joins the Rocky Mountain Fur Co., embeds in the Crow Nation, moves to California for the Gold Rush, discovers and promotes a key route through the Sierra Nevada, and works as an Army scout, among other endeavors.
“We think of the West as such an enormous region, and it is,” said Nelson, “but in the 19th century, the population was relatively small, and the chances that people would run into each other, or had heard of one another, were pretty good.”
The characters throughout the book are always on the move or influenced by those on the move.
Barceló migrates from the northern portion of New Spain, which encompassed a large part of southern and western North America, to Santa Fe and becomes one of the most powerful businesswomen in what would become New Mexico Territory.
Though she remains in place for decades, her life—and fortune—is affected by the people passing through: traders on the Santa Fe Trail after ownership of the region transferred from Spanish to Mexican hands, soldiers from both sides during the Mexican-American War, and migrants settling in the area after the United States took control of the territory.
The book rebuts aspects of the gunslinging, rugged individualistic narrative of westward expansion, weaving instead a tapestry of stories that show how the West became as diverse racially and culturally as it was geographically.
Chinese immigrant Polly Bemis, one of the book’s other protagonists, is trafficked from Guangzhou and Hong Kong to San Francisco, and eventually a majority-Chinese town in the mountains of Idaho.
She achieves a level of semi-celebrity, Nelson says, among later visitors who are stunned to discover in the remote rural town an elderly Chinese resident who has been there for 40 years.
“The reason they can’t believe it is because Chinese people have not been included in the frontier myth,” Nelson says.
The characters who populate Nelson’s new history go a long way toward explaining how the American West became the culturally and politically complex region it is today.
Why are other kids starving?Witnessing poverty as a child sparked Luiza Lima Vieira’s quest to vanquish hunger — but first, she had to learn to listen to her own body
A collection of features and graduate profiles covering Harvard’s 375th Commencement.
While growing up in Brazil, Luiza Lima Vieira recalls walking past children her age living on the streets of her native Sao Paulo and wondering why they went hungry and she did not.
Attempting to answer that question is what led Lima Vieira ultimately to the Harvard T.H. Chan School of Public Health, where she earned a master’s of public health in nutrition in December — all while navigating health struggles of her own.
“I didn’t understand why I had access to food and other children my age didn’t, and that didn’t make sense in my head at the time,” Lima Vieira said. “Injustice was something that always shaped my path and I wanted to do something about that.”
Lima Vieira — whose family moved to Ithaca, New York, when she was 16 so her mother could pursue medical studies — credits a symposium she attended as an undergraduate at Cornell as the catalyst for her turn to public health.
“I heard students from all different backgrounds talk about work they’d done in public health, and a lot of them mentioned nutrition,” Lima Vieira said. “That kind of clicked in my head. I had a lightbulb moment and since then I’ve been on a path to work at the intersection between nutrition, medicine, and public health.”
But Lima Vieira’s path to medical school took another turn at Cornell when she developed the neuromuscular condition myasthenia gravis. The autoimmune condition affects signaling between nerves and muscles and is marked by muscle weakness, particularly in the face, arms, and legs.
It took months to diagnose the disease. Treatment followed, involving surgery to remove her thymus gland and medication. The myasthenia gravis, Lima Vieira said, was a wake-up call for her not to sacrifice her health to academic and career ambitions.
“I wanted to be in the arts, I wanted to do medicine, I wanted to do nutrition, I wanted to do global health. I pushed myself to a point where my body gave up.”
“I like to do everything. I wanted to be in the arts, I wanted to do medicine, I wanted to do nutrition, I wanted to do global health,” Lima Vieira said. “I pushed myself to a point where my body gave up.”
So, instead of medical school when she graduated Cornell in 2022 with a bachelor’s degree in nutritional sciences, Lima Vieira went to work, taking a job at Action for Boston Community Development as the organization’s health and nutrition services manager. She worked there for two years, managing day care centers for disadvantaged children up to age 5. The experience got her interested in learning how large-scale programs and government policy might help that population.
In 2024, Lima Vieira entered the Chan School’s master of public health in nutrition program and spent the next 18 months learning not just about nutrition, but also about policy.
“I was never interested in politics, but while at Harvard I understood how important policy is,” Lima Vieira said. “Systemic change is the way to go.”
While at the Chan School, Lima Vieira was a teaching fellow for Paul Farmer Professor and chair of global health and social medicine Vikram Patel’s “Foundations of Global Mental Health” class. Patel said it was Lima Vieira’s enthusiasm for the class when she took it a year earlier that made her ask to be a teaching fellow a year later. Patel said she talked up the class so much to her classmates that a good proportion of her cohort took it. And even though her stint as a teaching fellow was her second time through the course material, she stayed engaged during class sessions.
“She was always available and always interested,” Patel said, adding that the course’s mental health focus has connections with nutrition in that people have used food to manage moods for a long time.
Food, in fact, is an important part of how Lima Vieira has managed her neuromuscular condition. In addition to taking medication, she makes sure she eats well and limits ultra-processed foods. She still exercises regularly — she’s a certified classical Pilates instructor — but builds in adequate recovery time, including sleep, between sessions.
Six and a half years of living with the condition have taught her to slow down and focus, to prioritize her health and concentrate on one thing at a time. In fact, after Commencement, she hopes that her new focus will be an old one: medical school. Though she graduated in December, she looks forward to participating with her family in Harvard’s Commencement Day ceremonies. She’s already taking steps, however, for what comes next, having moved back home to Ithaca, where she’s studying for the MCAT exam. She plans to apply to medical schools in June for classes beginning in fall 2027.
“I’ve decided I’m going to medical school and I wanted to take time to focus on this next step, which is studying for this exam, and be close to family,” said Lima Vieira, the eldest of three siblings. “We should not give up on pursuing our dreams even as challenges arise. Staying true to yourself while taking care of your body is the most important thing you can do for yourself and others. The challenges and twists and turns only make us stronger.”
Deterring the next nuclear arms raceExperts assess threat landscape amid war, lapsing treaties, declining faith in U.S. security guarantee

Experts assess threat landscape amid war, lapsing treaties, declining faith in U.S. security guarantee
Iran’s nuclear ambition, which is at the heart of its military conflict with the U.S. and Israel, is just one of several challenges that threaten to unravel decades of global nuclear security, scholars and practitioners said during an event at Harvard Kennedy School last week.
The discussion, moderated by Meghan O’Sullivan, director of the Belfer Center for Science and International Affairs at the School, reflected on the shifting framework of nuclear nonproliferation around the world and its critical importance to American national security, particularly as China accelerates its nuclear arms program in an effort to get on equal footing with the U.S. and Russia.
“I think there’s a very serious danger that we’re going to be in a new, probably more slow-moving but still, a new nuclear arms race competition” as a result, said Matthew Bunn, James R. Schlesinger Professor of the Practice of Energy, National Security, and Foreign Policy at HKS.
In 1963, President John F. Kennedy predicted a nightmare scenario in which perhaps 15-20 countries could have nuclear weapons by the 1970s. That panic led to the landmark Treaty on the Non-Proliferation of Nuclear Weapons. With 191 states signed on, it remains the foundational agreement that guides the use and spread of nuclear weapons and promotes disarmament around the globe. Limiting the spread of nuclear weapons, whether to adversaries or allies, remains a critical objective of U.S. national security.
“We don’t want to be in a world with 20 or 30 fingers on the nuclear button because there’s going to be much more chance that the nuclear button is going to get pressed and that the United States might be dragged into whatever takes place,” said Bunn.

That only nine countries today — the U.S., Russia, the U.K., France, China, India, Pakistan, Israel, and North Korea — are known to possess nuclear weapons is one of the “quiet successes” of global nonproliferation efforts over the last 60-plus years, panelists agreed.
But a recent Belfer Center task force and report on how the U.S. ought to approach nuclear proliferation today found broad, bipartisan consensus on the view that the steady, post-Cold War regime of treaties, institutions, and deterrence strategies has begun to break down.
In addition to the dwindling number of nuclear treaties, many of which have lapsed without replacement — including the New START treaty earlier this year — changing political attitudes have added a new hazard to nonproliferation efforts, analysts said.
The U.S. has begun warming to the notion of “allied proliferation,” in which it would be acceptable for friendly countries to have limited nuclear capabilities so they could defend themselves if attacked. It’s a view that upends decades of American policy in which non-nuclear allies had agreed to forgo weapons development in exchange for protection under the U.S. nuclear umbrella, a strategy known as “extended deterrence.” U.S. allies have grown increasingly uncertain about the credibility of that once iron-clad promise.
“There is no question Donald Trump has shaken the faith of our allies in the U.S. willingness to come forward in the terrible event that they are attacked with nuclear weapons” and to “respond with a U.S. nuclear weapon to that attack,” said Rose Gottemoeller, lecturer and research fellow at the Hoover Institution at Stanford who helped negotiate New START.
That promise, known as the extended nuclear deterrent guarantee, is a major aspect of U.S. treaty relationships with NATO, Europe, allies in Asia, Australia, and others. “So, everybody’s worried. I’m worried, to be honest,” she said.
On the other hand, she said, NATO’s capability and the physical infrastructure in Europe has “never been better,” thanks to the U.S. deployment of its most advanced warhead to Europe, the refurbishment of U.S. nuclear bases and handling facilities in Europe during the first Trump and Biden administrations, and allies’ agreement to buy F-35 fighter jets from the U.S. for nuclear missions.
To ensure the guarantee remains a strong deterrent to adversaries like Russia, Gottemoeller added, allies must “do everything they can to prove that it is an alliance that is ready to act” and that allies are well-trained and ready to participate alongside the U.S., if necessary.
Key nonproliferation institutions, like the International Atomic Energy Agency, which conducts nuclear weapons verification inspections, are becoming politicized by China, said Laura S.H. Holgate, a senior fellow at the Belfer Center who served during the Obama administration on the National Security Council and as ambassador to the IAEA from 2022 to 2025.
China, she said, has overwhelmed the IAEA with staff in a bid to leverage its development budget, “co-opt” the agency’s credibility, and advance China’s geopolitical influence and infrastructure gambit, the Belt and Road Initiative.
But there are steps the U.S. can take, outside of treaties, to ensure the past nonproliferation successes endure, the panelists said.
With a fourth generation of nuclear power reactors now under development, Holgate said now is the time to redesign them so they are both safer and less useful as a front for covert weapons-building.
Calling for the U.S. to be a more reliable partner to its allies, Bunn said the use of force to try to deter countries like Iran from developing weapons is not only “illegal,” it’s “ineffective.”
“I fear that the current war, while it has set back Iran’s nuclear capabilities somewhat, has greatly increased their motivation” to develop a nuclear weapon, Bunn said. He added that the probability Iran will have a nuclear weapon within 10 years is much greater today than it was just a year ago.
The event was the first in a new series of “convenings” by the Belfer Center named in honor of Albert Carnesale, a nuclear nonproliferation public policy specialist who spent more than two decades at the Kennedy School and mentored many of today’s top experts in the field.

AI and society expert warns new agentic releases to increase odds cybercriminals, hackers will be able to breach secure systems
Got debt or perhaps medical history you’d prefer colleagues, potential employers, neighbors, and friends not know about? An embarrassing email? According to Tyler Cowen, the odds will rise in the next year that more formerly secure digital systems could become breached.
The George Mason University economist, who has written and spoken extensively on AI, said new agentic AI models may help cybercriminals and amateur coders alike bypass online security — exposing millions of people’s personal data.
“If you have things you’ve said or done that are somewhere hidden but available that you’ll regret, get ready to deal with it,” Cowen, Ph.D. ’87, said at a recent campus event hosted by the Berkman Klein Center for Internet and Society. You can hope your information isn’t part of a targeted cache, but, “It’s possible that in the medium term, just everything comes out.”
According to Cowen, the Holbert L. Harris Chair of Economics at George Mason and chairman of the university’s Mercatus Center, AI companies like Anthropic and OpenAI are on the brink of releasing models with previously unseen coding and more independent, agentic capabilities that will be no match for the older security software on which many companies rely.
“If you have things you’ve said or done that are somewhere hidden but available that you’ll regret, get ready to deal with it.”

“I believe that it does give the person that controls it the ability to hack into virtually all human systems, no matter how safe or protected we might have thought they were. And you can do this at not too great an investment of time, energy, and money,” Cowen said.
Earlier this month, a preview of Anthropic’s model known as Claude Mythos was released to tech partners, while OpenAI has made a similar move unveiling its GPT-5.4.
Because of their advanced capabilities, Cowen said, giving partner companies the opportunity to test the tech will allow those with access to better prepare their cyber defenses.
“It may accelerate the elevation of these, say, 50 institutions that are quite protected,” he said. “What you’ve done on Amazon and Facebook is the safest, because they know to invest in protection ex ante, and they have the resources to do so.”
But he said, it doesn’t mean these firms will be able to anticipate every vulnerability. Even the AI companies themselves could be at risk for unforeseen breaches.
“Anthropic and OpenAI will protect themselves against, say, external hacks, but internally, any institution is vulnerable because you hire employees. There are not security clearances of the sort you would have at the Pentagon, including at top AI firms,” Cowen said.
Moreover, Cowen warns, government agencies will likely be targets — especially at lower levels.
“I think our national security establishment has been pretty clued in on this for a while. It doesn’t mean they’ll have perfect defenses, but they will be relatively prepared,” he said. “What will be embarrassing is all the smaller parts of our government … all their deliberations, emails to each other, whatever they have will all come out, and it will just be very embarrassing, and those parts of government will lose their credibility.”
To prepare for the new models, Cowen advises that government should implement regulations to create a system of laws and penalties governing AI agents. Those would include registration, the ability to turn them off, and mandating they be connected to cloud computing to increase transparency.
“Ideally, I would like to see AI agents capitalized, and the kind of minimum capitalization required as we do for banks and many other financial institutions,” Cowen said. “But we are going to have what you might call anonymous AI agents, which are not owned or traceable to anyone or any institution. And how those will be governed is a big challenge.”
And in the most ideal world, making progress toward addressing the myriad challenges heading our way would be creating new state capacity for AI, Cowen said.
“Our government is very far from being able to do that … Let’s get the best from it we can,” he said. “We will only get it right by trial and error and making mistakes along the way.”
Dangers coming from inside the houseJohn D. Spengler reflects on 50-year career of clearing the air — including in hockey rinks and on airplanes
John D. Spengler reflects on 50-year career of clearing the air — including in hockey rinks and on airplanes
John D. Spengler’s research has helped lead to smoking bans on airplanes and heightened awareness of childhood asthma in public housing. Yet his pioneering focus on indoor air quality got its start while he worked on a landmark study exposing the health risks of outdoor pollution.
Spengler and other researchers working on Harvard’s “Six Cities” study of 8,000 Americans in six cities — launched in the 1970s — considered subjects’ smoking history and made a surprising discovery.
“Seventy-five percent of the kids lived with smoking parents or they were cooking with gas for nitrogen dioxide particles,” Spengler said during a recent Harvard talk reflecting on his 50-year career. “So Topeka, Kansas, had as much air pollution that the kids and adults were breathing as a dirty city, because of indoor sources. That made it very complex. So that got us really curious about the indoor environments.”
Spengler, the former Akira Yamaguchi Professor of Environmental Health and Human Habitation, retired on Jan. 2 to take up a research professor role. Last week he sat down with longtime collaborator Linda Powers Tomasso, a research associate in environmental health in the Harvard T.H. Chan School of Public Health’s Leadership Studio, to discuss five decades of environmental health progress.
The Six Cities fieldwork began during the oil embargoes of the 1970s, which prompted moves toward energy efficiency. But sealing up cracks and better insulating homes just made indoor air worse, Spengler said.
“All of a sudden, people were tightening up homes, they were shutting off ventilators for schools to save money,” Spengler said. “Air pollution indoors got worse, so that those things sort of converge to say this is an important area and many doctoral students’ dissertations later, it’s still important.”
Six Cities is credited with prompting Congress to adopt the Clean Air Act Amendments of 1990. Those amendments tightened restrictions on particulate pollution, sulfur dioxide, and nitrogen oxides, which cause acid rain, and set tougher pollution controls on vehicles. In the years since, the study has come under assault by industry groups and some politicians looking to roll back the Clean Air Act restrictions.
Spengler’s work on indoor air pollution continued through the 1980s and the decades since. In 1983, he co-authored an influential report that investigated, among other things, air pollution on airplanes. After bringing air quality monitoring equipment on flights, they found pollution levels could top 1,000 micrograms per cubic meter of air — smokier, Spengler said, than “the smokiest bar you ever went to.” In 1988, legislation led by then-Rep. Dick Durbin of Illinois banning smoking on planes became law.
Also in the 1980s, Spengler, who played recreational hockey, found himself wondering why ice rinks smelled like garages, and brought his air pollution instruments to investigate. He found high levels of carbon monoxide, carbon dioxide, and nitrogen oxides due to the internal combustion engines on the ice-smoothing Zamboni machines. That coincided, he said, with cases of hockey players passing out during tournaments due to carbon monoxide. He studied the problem regionally and internationally and reached out to the machines’ manufacturers, who began to explain to rink owners safe use of the machines.
In recent decades, as his work on childhood asthma in Boston’s public housing progressed, Spengler worked with the Boston Housing Authority to reduce what were found to be triggers: cigarette smoke, dust mites, pets, and cockroaches.
Spengler was also instrumental in making changes on Harvard’s campuses. He created the master’s program in environmental management and sustainability at the Harvard Extension School. And, with former Vice President for Administration Thomas Vautin, he founded the Harvard Green Campus Initiative, which was a hub for sustainable operations on campus. With the support of several Harvard presidents, the Green Campus Initiative leveraged current research to make Harvard’s operations more sustainable and evolved into today’s Office for Sustainability.
“It is embedded in everything the University does and we should all be proud that this University has more green buildings certified than any campus in the world,” Spengler said.
If there’s a unifying theme, Spengler said, it’s that these indoor air quality issues affect virtually everyone and, though materials may change, they have similar causes and require a systemic solution, taking into account ventilation, filtration, and sustainability. For example, in his studies of public housing, many business managers who found pests on their property would spray pesticides without considering how that would affect the home and its occupants.
“The common denominator is that everyone lives somewhere. We all have residences and, as our time activity studies say, we spend a lot of time indoors and a lot of time in our houses.”
John Spengler
“The common denominator is that everyone lives somewhere. We all have residences and, as our time activity studies say, we spend a lot of time indoors and a lot of time in our houses,” Spengler said. “The issues there might change with modernity of products and outgassing, but the issues are pretty much the same. How do you treat water, dampness, mold, infestation, insects? These are everywhere but it’s never thought of as a whole system. How does the house handle this?”
In explaining his success, Spengler praised the strong teams he was part of at the Harvard Chan School; his family, who supported his work; and his students, many of whom he’s kept in touch with.
“They have so much to teach me, to watch their careers change, watch how they’ve raised their families, where they have impacts in their communities, their colleges, and on the global stage,” Spengler said, adding that some former students lead schools of public health, and one is the first woman president of a major university in Taiwan. “Who wouldn’t want to see this unfold in front of your eyes?”

If you give artificial intelligence a goal of maximizing profit, how far will it go?
AI agents appear capable of lying, concealing, and colluding, according to new research from Harvard Business School.
Researchers found that AI agents — software trained to perform tasks independently — engaged in a “broad pattern” of misconduct after being asked to manage a simulated vending machine business and maximize profits for a year. The agents were neither instructed to cut legal or ethical corners nor prohibited from doing so.
“What’s unambiguous looking at the models is that the misconduct we observed — from not paying a customer refund or deciding to collude on prices — was not an accident. It was deliberately done by agents to maximize profitability,” said Eugene F. Soltes, the McLean Family Professor of Business Administration at HBS and first author of the working paper.
Soltes and co-author Harper Jung, a PhD student studying accounting and management at HBS and Harvard Griffin GSAS, hope their research will serve as a starting point for more conversation about AI safety in the context of business management control.
The research for the paper, which the group aims to publish and is currently out for peer review, was done in collaboration with Andon Labs, an AI safety company focusing on testing AI models in realistic business operations.
In experiments, 20 commercially available AI models from major firms, including Anthropic’s Claude Opus 4.6, DeepSeek v3.2, and OpenAI’s GPT-5.1, independently operated a vending machine over the course of a simulated year.
“People might assume that machines are deliberative, while humans rely on shortcuts and are vulnerable to bias. But it turns out that, under similar constraints, agents reproduce the same myopic and biased behaviors we associate with people.”
Eugene Soltes
Tasks included searching for suppliers, buying products, and engaging with customers.
In some experiments, agents operated solo; in others, four agents operated simultaneously in a shared market, where they could communicate with rivals via email.
Agents started with $500 and a small inventory of chips and sodas.
“They had to figure it out themselves,” said Jung. “Each agent had to independently search online for suppliers, negotiate wholesale prices, set its own retail pricing, and handle customer complaints.”
Jung and Soltes said the agents demonstrated impressive business savvy.
“The best models had the capacity to negotiate and calculate valuations like a top-notch M.B.A. student,” Soltes said.
“When we went through the deliberations and the exchanges the agents made with each other, we were just in shock,” said Jung. “I was amazed at how far these machines can go.”
The agents’ misconduct ranged from the questionable to the comical to the potentially criminal and included denying refunds by claiming defects were normal product variation; inventing nonexistent corporate policies to avoid processing returns; and colluding with competitors to fix prices.
In one instance, agents formed what researchers described as a “three-person cartel,” which the agents named the Bay Street Triumvirate. The alliance fractured, though, when one agent discovered another was undercutting cartel prices, which it called a “declaration of war.”
The simulations also supplied constraints: Agents were charged a $2 per day operating fee plus a token usage fee — effectively turning time spent “thinking” into an operating expense.
In response, the agents sought to economize. For instance, Soltes said, internal reasoning logs showed agents shifting from carefully weighing refund decisions to dismissing most requests outright, often without review.
“The agents come to the realization that ‘thinking’ about giving a refund is itself a cognitive burden, and so they just ignore it altogether in some circumstances,” Soltes explained. “People might assume that machines are deliberative, while humans rely on shortcuts and are vulnerable to bias. But it turns out that, under similar constraints, agents reproduce the same myopic and biased behaviors we associate with people.”
The research raises questions about accountability for AI developers and regulators.
The reasoning logs, Soltes said, can sometimes be read as resembling mens rea — the “guilty mind” concept in criminal law used to establish intent. Yet when an AI agent behaves improperly, responsibility is far harder to determine.
“Does it rest with the company that deployed the system, the AI firm that created the model, or the manager who chose to use it?” he asked.
“The most straightforward answer may be to hold the individual managers overseeing the software responsible for its actions, on the assumption that they will monitor and supervise its behavior,” he said. “But that solution also creates a different issue, since many of the promised efficiencies of autonomous AI systems begin to disappear if a human must remain in the loop at every decision point.” A thorny problem, but one that business leaders and lawmakers must deal with, hopefully sooner than later, researchers say.

Blood test has potential to detect earliest signals of Alzheimer’s diseaseNew study suggests higher levels of pTau217 predict a faster progression, even when initial brain scans appear normal

New study suggests higher levels of pTau217 predict a faster progression, even when initial brain scans appear normal
A new study by Harvard-affiliated investigators at Mass General Brigham has found that a blood test for an Alzheimer’s disease biomarker, plasma phosphorylated tau 217 (pTau217), has the potential to predict progression of the illness years before symptoms or brain scan changes.
The findings may help make disease prediction simpler and easier, and could indicate who may be at risk for cognitive decline. The results are published in Nature Communications.
“We used to think that PET scan detection was the earliest sign of Alzheimer’s disease progression, revealing amyloid accumulation in the brain 10 to 20 years before symptoms appear,” said lead author Hyun-Sik Yang, a Harvard Medical School assistant professor of neurology at Brigham and Women’s Hospital and an associate member of the Broad Institute of MIT and Harvard. “But now we are seeing that pTau217 can be detected years earlier, well before clear abnormalities appear on amyloid PET scans.”
Last year, the U.S. Food and Drug Administration cleared the first blood test for Alzheimer’s disease, paving the way for a cheaper, less-invasive alternative to lumbar punctures and PET scans. The new study by Yang and colleagues adds important evidence about the predictive potential of these kinds of blood tests.
This prospective cohort study followed 317 cognitively healthy older adults from the Harvard Aging Brain Study for an average of eight years. Participants, who ranged in age from 50 to 90 years, had blood tests for pTau217, repeated amyloid and tau PET scans, and long-term cognitive testing. The researchers examined whether baseline and changing pTau217 levels predicted future abnormal buildup of amyloid, misfolded tau proteins inside brain neurons, and cognitive decline.
Researchers found that higher levels of pTau217 predicted a faster buildup of Alzheimer’s disease pathology, even when initial brain scans appeared normal. Increases in pTau217 frequently occurred before amyloid PET scans became positive, highlighting the biomarker’s ability to detect changes early. Importantly, participants with low pTau217 levels at the start of the study were very unlikely to accumulate significant amyloid-beta on their PET scans over many years of follow-up. The amino acid fragments can form sticky plaques that are one of the hallmarks of Alzheimer’s.
“What stood out in our study is that even when amyloid scans appear normal in the clinic, the pTau217 biomarker can identify individuals who later become amyloid-positive,” said Yang. “It also shows that those with low pTau217 levels are likely to stay amyloid-negative for several years.”
While it’s too early to recommend pTau217 testing for older adults, Yang and his colleagues hope the study results will serve as a scalable screening tool for clinical trials targeting Alzheimer’s disease prevention and help identify individuals at higher risk. Eventually, biomarker blood tests could be used for routine health maintenance and may offer a more affordable alternative to amyloid PET scans.
“As the field is evolving quickly, we’re excited to see discoveries on the research side being rapidly translated to clinical application,” said co-senior author Jasmeer Chhatwal, an HMS associate professor of neurology at Brigham and Women’s.

Voting goes to courtElection law expert assesses challenges to state authority as parties look ahead to midterms
Election law expert assesses challenges to state authority as parties look ahead to midterms

Harvard Staff Writer

As political candidates prepare to face off in the November midterms, lawyers around the country have been fighting on another important front — the election’s administration.
This month, a federal judge dismissed the Justice Department’s demand that Massachusetts turn over its voter lists, one of 30 such cases nationwide involving sensitive state voter data. Other election conflicts involve mail-in ballots and voter identification rules.
While these disputes are unlikely to radically change the midterms, they come at time when trust in U.S. elections is already weak across party lines, notes Bob Bauer ’73, an expert on presidential power and election law.
Legal adviser to Presidents Joe Biden, Barack Obama, and Bill Clinton, Bauer, who visited campus April 10 to meet with students at the Kennedy School’s Institute of Politics, now co-leads the Bipartisan American Election Project, which advocates for the nonpartisan administration of elections. He is also a professor of practice and distinguished scholar in residence at NYU Law.
In this edited conversation, Bauer discusses the legal landscape around voting rules.
Where do things stand on this front?
Over recent years, there has been an extraordinary increase in lawsuits. What is distinctive now is this confrontation over assertions of executive authority to set the rules in federal elections and otherwise have an impact on the way elections are administered.
Under the Constitution, administrative responsibility for the elections is vested in the states unless Congress chooses to step in and specify rules for federal elections, in particular. Nowhere in the constitutional scheme is the president mentioned. President Trump is actively testing that, and that has produced a significant amount of litigation, particularly in relation to the Executive Orders he issued in March of 2025 and also in March of 2026.
There is a separate piece of litigation, initiated by the Republican National Committee, that is before the Supreme Court. That has to do with the so-called postmark voting rule. The court has to decide: May states provide that ballots have been lawfully received if postmarked by Election Day, even if the state provides a grace period for counting them for a certain number of days after Election Day? That case is distinctive because it’s about to be decided.
Which type of challenge could have the greatest effect on voting in the fall?
The voter roll cases. While the administration has met with no success in the courts up to now, that’s a very significant case. It represents an extraordinary and, I think, unconstitutional assertion of authority that somehow the federal government is going to create a national voter list and compel the states to use that particular list.
Congress has not passed the SAVE Act, a top legislative priority of the president that would require voters nationwide to produce not merely identification, but proof of citizenship. Could it still potentially factor into the midterms?
There is no indication that the Republican leadership in the Senate is going to do what Trump has urged them to do and cast the filibuster rules aside and permit the bill to be jammed through on a majority vote. So far, there’s no indication that that is going to happen. It will fail in the Senate.
What tools do states have to prevent or limit the federal government’s hand in their elections?
They have the ability to bring their defense against these claims before the judiciary and they’ve done so. And then, throughout the electoral process, the state courts sit in judgment over disputes over election rules and the application of those election rules. Periodically, the federal courts will intervene. They’ll step in if there’s a federal constitutional claim. But for the most part, you have states setting up the rules under their codes and adjudication under state law. That applies throughout the entire process, from the registration period all the way to the post-election recount challenge period. So, there are multiple ways that the legal processes in these states can be invoked to defend against illegal claims or attempts in the aggregate to subvert the outcome of the election.
Is the Supreme Court likely to weigh in on more of these cases before the election?
No question, there have been attempts by the administration to use the emergency docket to try to get quick relief before the case can be heard in full. Now, sometimes that doesn’t work; witness the tariff cases. Ultimately, the court heard the entire case and disallowed the president’s exercise of tariff authority under the emergency statute that he was using.
I do think there are people who conflate the majority of the court’s conservatism as some desire to protect and help Trump. It’s a conservative court; there’s no question about that. But I also think that on some of the issues we’re talking about, he pushes so hard in a direction that the conservatives themselves cannot support, directions that I wouldn’t even consider classically conservative.
Many observers are worried about the confusion and distrust these challenges may create for voters. Is there some way to mitigate those effects?
Yes. The professionalization of election administration since 2000, in particular, has been extraordinary. There are a corps of administrators around the country, Democrats and Republicans, who know how to run elections, who are continually perfecting the way they run elections. Elections will never be perfect; mistakes will always be made. Then the question is, how do you learn from the mistakes and how do you correct them when they happen?
Yes, there is still a lot of suspicion. There’s much higher doubt about the integrity of the process than there was before Trump. But all that being said, civil society, the private sector, in many ways stands up and defends these officials when they’re under attack because the work that they do is really very good.
One other point: It is very difficult to reverse the outcome of an election that is not close. That’s true in an individual case, and that’s true in the aggregate. So, if the Democrats win by a significant number of seats, there’s no practical, legal, conceivable way that Trump, if he were so disposed, can reverse the outcome.
Three alumni leaders honored with Harvard MedalAnnual award recognizes exceptional service.
A collection of features and graduate profiles covering Harvard’s 375th Commencement.
Thomas A. Dingman, Deborah Kaufman Goldfine, and Walter H. Morris Jr. have been selected by the Harvard Alumni Association to receive the 2026 Harvard Medal.
First awarded in 1981, the Harvard Medal recognizes extraordinary service to the University in areas that include leadership, fundraising, teaching, innovation, administration, and volunteerism. Alumni, former faculty and staff, and members of organizations affiliated with the University are eligible for consideration. The medals will be presented to recipients on Harvard Alumni Day, June 5.
Thomas A. Dingman ’67, Ed.M. ’73
Compassionate, energetic, and widely beloved, Dingman has served at the heart of the Harvard community for 45 years, bringing his generous spirit to pivotal roles that have shaped the undergraduate student experience.
As dean of freshmen for 13 years, Dingman prioritized creating an environment that nurtured first-years’ sense of belonging on campus and connection with their peers. Frequently found eating with students in Annenberg or strolling the Yard in his bright-red jacket, he launched several initiatives that have become time-honored traditions at the College — including Convocation, the ceremony that marks students’ official start as members of the Harvard community, and the Reflecting on Your Life program, group sessions that encourage first-years to ponder larger questions about their time at Harvard and beyond.
Dingman reorganized the Freshman Dean’s Office staff to better support students’ transition to College and established more opportunities for undergraduates to engage with faculty outside the classroom.
After working as a secondary school teacher, Dingman began his 45-year career at Harvard as an assistant director in the admissions office. Before becoming dean of freshmen, he held a range of administrative and mentoring roles at the College, including assistant and associate dean of the College, resident dean in Leverett and Dudley Houses, director of the Parents Association, and coordinator of disability services. He was awarded the FAS Administrative Prize in 1996.
After retiring in 2018, Dingman continued to serve Harvard as a special adviser to the dean of Harvard College, and he eagerly helped plan in-person Commencements for the classes of 2020 and 2021 following the pandemic.
Dingman continues to advise first-year students and is an adviser for the renewal of Eliot House. He remains involved with the Harvard Alumni Association as a College director on the HAA board, a mentor to first-year directors, and an alumni interviewer.
Deborah Kaufman Goldfine ’85
Dedicated to strengthening Harvard athletics, engaging alumni, and supporting students, Kaufman Goldfine has been a loyal Harvard volunteer and philanthropic leader for decades. A former three-time captain of the women’s tennis team, she is a lifelong champion of women’s tennis and women’s sports.
Kaufman Goldfine has played a central role in alumni engagement and fundraising for athletics as executive chair of the Harvard Radcliffe Foundation for Women’s Athletics, and as a longtime member and co-chair of the Friends of Harvard Tennis. In 2024, she spearheaded the 50th Anniversary Celebration of Harvard Women’s Tennis, which raised more than $1 million for women’s tennis and reconnected a broad network of alumnae. She served multiple years as a volunteer assistant women’s tennis coach and established a mentoring program connecting student-athletes and alumni. She was also a member of the Harvard Visiting Committee for Athletics. Kaufman Goldfine’s tenacity and institutional knowledge have benefited the larger University community in roles on the Advisory Committee on Shareholder Responsibility and as a College director on the HAA board.
Deeply engaged with her class, Kaufman Goldfine has co-chaired every reunion since her 10th and has been a Harvard College Fund volunteer for 35 years. She has co-chaired the Schools and Scholarships Committee in Newton, Massachusetts, for 20 years, working with hundreds of alumni volunteers, interviewing countless College applicants, and serving as a mentor to numerous undergraduate students.
Kaufman Goldfine has been recognized for her efforts with the Hiram Hunn Award for admissions work, the John P. Reardon Jr. Alumni Award for extraordinary service to the University through leadership and engagement activities, the Albert H. Gordon ’23 Award for college fundraising, and various honors by the Harvard tennis program.
Walter H. Morris Jr. ’73, M.B.A. ’75
A valued and steadfast member of the Harvard community, Walter Morris has worked unwaveringly to cultivate and strengthen alumni engagement and foster lifelong learning in a variety of roles for the HAA.
As HAA president from 2008 to 2009, Morris focused on creating opportunities to build vibrant communities of Harvard alumni in cities across the U.S. and around the world. He helped expand Shared Interest Groups (SIGs) — what he called “clubs without walls” — that connect alumni by interest and background. During his tenure, the number of SIGs grew from 21 to 30 organizations, and the HAA launched the inaugural Global Networking Night, an annual program bringing thousands of Harvard alumni together through informal networking events.
Returning to Harvard often to attend lectures and presentations, Morris embraced a love of lifelong learning and worked to foster new avenues for fellow alumni to expand knowledge and remain connected to the University.
Morris first became involved with the HAA in 1995, when he served on its Graduate Schools Committee at the urging of then-executive director Jack Reardon ’60, who was Morris’ first-year proctor and mentor throughout College. Since then, he has served as an HAA Elected Director, as chair of the HAA Awards Committee, on his College reunion committees, and on the Committee for the Happy Observance of Commencement for more than a decade. He received the John P. Reardon Jr. Alumni Award in 2011.
A longtime and active member of the Harvard Black Alumni Society and the HBS African-American Alumni Association, Morris has participated on various panels and in Harvard Black Alumni Weekend. He has also been involved in the Harvard Club of New York and held various leadership positions with the Harvard Club of Washington, D.C.
A former banker, Morris is a retired principal at Ernst & Young LLP.
Nominations for the 2027 Harvard Medal should be submitted by June 30, 2026 via the online form. Nominations received after the deadline will be considered for the following year.

Experts say capabilities of agentic AI rising, along with risk to personal data, economy, national security
As new agentic AI models continue to come online, cybersecurity experts laud their ability to sift through vast quantities of data quickly and autonomously — making them great tools to help fight cybercrime.
But, they warn, those attributes could also be put to work by bad actors to hack systems and risk our personal data, our economy, and our national security.
Cybercrime, recent data from IBM shows, is rising rapidly. According to a 2026 study, the company found that cyberattacks aimed at public-facing software and systems applications — many of which utilized AI — had a year-over-year increase of 44 percent.
High-profile attacks include the November data breach of Anthropic — the AI company behind the Claude Code assistant. Attackers were able to use their own AI models to scan for weak spots in its source code and publish its inner workings.
“The unfortunate thing is that the bad people only have to win once in some sense, whereas the defenders have to win all the time,” said James Mickens, Gordon McKay Professor of Computer Science. “To me, at least, that’s a concerning aspect of what it means to think about agentic cyber security, attacks and defenses.”
“A year ago, we still had email messages in our inbox that had misspellings that were not colloquial English, that were easy to identify if you were vigilant. Now, all those signals are gone.”
Robert Knake
“A year ago, we still had email messages in our inbox that had misspellings that were not colloquial English, that were easy to identify if you were vigilant. Now, all those signals are gone,” said Robert Knake, panelist and partner at Paladin Capital, a cyber-venture capital group.
Knake also served as the first deputy national cyber director for strategy and budget in the newly created Office of the National Cyber Director at the White House from 2022 to 2023.
In Knake’s view, the federal government needs to start requiring the private sector to take greater steps to prevent attacks that jeopardize consumer and national safety.
“We’re not at a place where we can say any error in your software that leads to a harm, you need to be responsible for. That will kill off software development,” he said. “But we could create a safe harbor in which we say, if you’ve done … these basic things, like using the most current and known secure version of an open-source package … you should not be held liable for a bad outcome from your software. If you haven’t done them, you should be.”
According to Mickens, this type of regulatory scheme may be easier said than done — especially as the cybersecurity landscape continues to change.
For decades, he said, tech companies like Microsoft and Amazon have included stopgaps in their codes to prevent traditional internal security breaches, without formal government regulation.
“The big difference with AI is that the threat model changes,” Mickens said. “Essentially, there’s some human in a chair that’s outside of the data center who’s sending evil commands to the code that’s running in the data center and otherwise trying to trick it into being evil with AI.”
Any conversation on mandating security measures against outside forces and AI will have to clearly define the liabilities at stake and the types of hardware and software that would ensure compliance he added.
Josephine Wolff, associate dean for research and professor of cybersecurity policy at the Fletcher School at Tufts University, added that regulation could become especially tricky if the private sector is asked to be proactive in finding vulnerabilities across large networks.
“Documentation and inventories are both really important and really hard,” she said. “Can you inventory all of the code that’s running on your computers so that if there’s a vulnerability, if something goes wrong, you can at least know where you need to look?”
But while the liability piece remains murky after online systems are breached, all the panelists agree that companies should not be responsible for retaliation against the hackers. A school of thought in combatting cybercrime argues firms that are hacked may be in a unique position to “hack back.”
“I think that the more actors you have out there in the name of self-defense, intruding on other people’s networks, the less likely you are to de-escalate anything,” Wolff said. “The idea that you’re going to bring in the private sector and have that lead to anything but greater chaos seems hopelessly optimistic to me.”
Moreover, she added, the idea that large companies like Google and Microsoft would make sophisticated surgical strikes to take down small clusters of servers launching denial of service attacks at them is unlikely.
“I think you would have a whole bunch of much crazier firms with many fewer lawyers feeling like, here’s our opportunity to take on North Korea. And that doesn’t seem to me like a safer world.”
Mickens imagines a world in which offloading retaliation efforts to the private sector could also lead to corporations running unmanned agentic firewalls.
“It sees an intrusion, traces the hackers back to London, Berlin, and then does something offensive. I think that world very quickly degenerates into essentially high-frequency trading, except now in cyber security, where you just have a bunch of algorithms going back and forth and reacting to each other in very real time,” he said. “I don’t think we want to get into that world for the same reason that, in general, we don’t want to sort of deputize vigilantes in the physical world.”
And as for combating phishing scams bolstered by AI, the panelists imagine a world, equally obscure at present, that would allow genuine human identities to be verified online.
“This has been a problem in the ecosystem going back 30 years,” Knake said. “I think that the threat of AI just means that we are going to have to know with certainty who we are dealing with, and that it is a real person if they are claiming to be a real person, so that we can trust who you’re engaging with.”
Mickens added that while digital identification could be a viable option to combat cybercrime moving forward, it may hit some roadblocks because of how consumers use the internet.
“One reason digital IDs have traditionally struggled is that there are many scenarios in which someone wants to be identified as part of their identity, but not the full identity,” he said. “For example, if I’m the victim of domestic abuse or I’m a runaway kid or whatever, I may want someone to know I am a human but I don’t want them to actually know my real name. I want the things that I say to be associated with a particular pseudonym consistently, but I don’t want it to be my real name. Those types of practical problems would need to be solved to make some of these proposals real.”
Overall, tech companies and government agencies are facing constant changes in AI capabilities. Along with the changes come both challenges and opportunities to harness technology.
“The ability to have agentic AI essentially sitting over your shoulder, on your phone, on your computer, looking at everything you’re doing and saying this certainly looks like it’s a kill chain for a fraudulent scheme, is there,” Knake said. “We can do this. We just need to find the right market players who will make that investment and build that technology.”

Researchers find 24.7 million Americans live in dental deserts, with transportation and specialty care the steepest barriers
For millions of Americans living in rural communities, getting specialized dental care can mean driving an hour, or more, just to sit in the dental chair. A patient in rural Wyoming needing a root canal may travel over an hour to see an endodontist. A child in South Dakota who needs specialty pediatric dental care may face an 80-minute drive. For some families, that distance means delayed care. For others, it means no care at all.
New research from the Harvard School of Dental Medicine (HSDM) shows that millions of Americans face serious barriers to dental care and that those barriers are especially severe in rural communities. The findings, recently published in the Journal of Dental Research and SSM Population Health, reveal growing geographic divides in access to dental specialists and workforce trends shaping rural shortages.
“We found that rural residents must drive, on average, more than three times longer than urban residents for specialty dental care,” said Hawazin Elani, associate professor of oral health policy and epidemiology at HSDM. “Where you live can determine whether you receive timely treatment — or end up in the emergency room.”
Rural residents face substantially longer travel times for care, especially for specialty dental services, for which average drive times were 3.2 times longer than those of urban residents. In several states — including Alaska, Montana, Nevada, North Dakota, South Dakota, and Wyoming — drive times to dental specialists often exceeded an hour.

The struggle to find specialty care
The studies show that rural disadvantage begins with the general dental workforce and deepens when specialty care is needed. In rural areas, there was roughly one dentist for every 3,850 people, compared with one for every 1,470 people in urban areas.
The national specialty-care analysis examined geographic access to dental specialties: endodontics, oral and maxillofacial surgery, orthodontics, pediatric dentistry, periodontics, and prosthodontics. Among them, prosthodontics — critical for restoring missing teeth and helping patients eat and speak comfortably — emerged as the least accessible specialty. An estimated 85.5 million Americans live more than 30 minutes from a prosthodontist, and more than 10 percent face travel times exceeding an hour. These gaps are especially concerning for older adults in rural communities who depend on dentures or implants to maintain nutrition and quality of life.
While general dentists in rural areas often broaden their scope to meet community needs, certain procedures — such as complex surgical extractions, pediatric sedation, or full-mouth rehabilitation — require advanced training that general practice alone cannot fully replace.
Factors influencing where dentists practice
A study recently published in Scientific Reports also examined the broader dental workforce and what factors shape where dentists choose to practice. Early career dentists were considerably likelier to work in rural and underserved communities, but that likelihood declined as careers progressed. Specialists were substantially less likely than general dentists to practice in shortage areas, reinforcing geographic imbalances in advanced care.
Economics also appeared to play an important role. The studies found that moderate educational debt — approximately $200,000 to $600,000 — was associated with a greater likelihood of practicing in underserved settings, particularly Federally Qualified Health Centers. In dental shortage areas and rural shortage areas, higher debt was also generally associated with a modest increase in the likelihood of practice. But very high debt levels, above $800,000, were associated with a lower likelihood of practicing in some underserved settings, suggesting that financial pressures may shape where dentists choose to build their careers.
“These patterns point to a structural workforce challenge,” Elani said. “Rural communities often depend on younger dentists, yet retention becomes difficult over time.”
The findings carry important implications for workforce policy, according to Marko Vujicic, chief economist and vice president of the Health Policy Institute at the American Dental Association and a co-author of the workforce study.
“This type of research is vital for unpacking the true underlying factors associated with dentist location choices. Policy interventions need to incorporate this kind of evidence, because at the end of the day, we have not made much progress at all as a nation in addressing rural area shortages of dental care providers,” said Vujicic. “This is despite significant expansions in dental school enrolment overall, including building more dental schools.”
According to HSDM researchers, rural dental access is not only about whether patients can see a provider, but whether they can obtain the level of care their conditions require within a reasonable distance.
“As national conversations continue around rural workforce shortages and provider distribution, the research points to the need for strategies that expand specialty pipelines, support rural training programs, address debt burden, and improve long-term workforce stability in underserved communities,” said Elani.

City leaders meet to discuss ‘highly visible and highly unacceptable’ crisis
Three American mayors gathered at Harvard on Tuesday to share the strategies they’ve deployed in their cities to address homelessness.
An estimated 770,000 people were homeless in the U.S. as of the most recent data, up 18 percent from the previous count. Of those, about one-third were unsheltered, meaning they were sleeping on the street, while two-thirds were living in homeless shelters, temporary housing, or “doubled up” with friends or relatives.
It’s a crisis that affects much more than housing, said panelist Monroe Nichols, mayor of Tulsa, Oklahoma. “Public safety, public health: All the things we do as a city are impacted by the issue of homelessness.”
The forum — held at the Chan School of Public Health and co-sponsored by the Bloomberg Center for Cities, the Initiative on Health and Homelessness, and the Harvard Urban Health Initiative — was part of the Bloomberg Center’s Global Mayors at Harvard Day. In more than 30 events across different schools on campus, 45 mayors — representing 16 countries — from the Bloomberg Harvard City Leadership Initiative gathered to share perspectives, compare experiences, and explore solutions to the complex challenges of local governance.
“We are here because we understand that homelessness represents a highly visible and highly unacceptable humanitarian crisis,” said moderator Howard Koh, the Harvey V. Fineberg Professor of the Practice of Public Health Leadership at the Chan School and inaugural chair of the Initiative on Health and Homelessness. “But we can solve it if we have everybody in this room, and all the leaders and all the sectors across society, and especially our political leaders, our mayors, stepping up and taking charge of this crisis that is growing by the day.”
Joining Nichols on the panel were mayors Patrick Farrell of Huntington, West Virginia, and Kaarin Knudson of Eugene, Oregon. Koh asked each mayor to describe the challenge of homelessness in their community and their unique approaches to fixing it.
Farrell traced homelessness in Huntington to the ongoing effects of the opioid epidemic. He said that solving the issue is not only about the well-being of people living on the street, it is also about the perceived safety of the community.
“We weren’t going to be able to attract businesses; we weren’t going to be able to fix the infrastructure,” Farrell said. “We weren’t going to be able to give hope to the young people in our city who want to stay. It became the first thing to tackle to be able to build everything else.”
Farrell’s approach has been to convene hospitals, businesses, nonprofits, and government to work together on the problem. He launched a public safety dashboard to track the city’s progress.
“We had to show them that when we take somebody living on the street to the ER and back to the street, then to jail, it’s the most costly, least effective way to solve this problem.”
In Tulsa, Nichols also organized his community around hard numbers.
“We have about 3,000 people who become homeless in our community every single year. So driving indicator No. 1 is, do we have 3,000 units in our community that we can get those people into? We’re not there yet, but that’s the goal.”
He also pointed to what he called a rapid exit strategy. When he took office, the time between a homeless Tulsan’s first interaction with a caseworker and the time they got housing was 220 days — and that was an average. His administration shortened the wait time to 37 days.
Knudson said good data collection showed her that Eugene actually didn’t need many more units of transitional housing. “We need maybe 100 more spaces, maybe 200, but what we really need to work on is the pipeline out of that experience.”
She said that due to federal funding cuts, Eugene had lost some of the case managers who helped people out of transitional housing and into permanent housing.
The mayors highlighted the systemic challenges facing their communities — challenges that require investment beyond the level of city government.
In Eugene, the housing vacancy rate has been below 5 percent for a decade, said Knudson, who has taught planning and urban design at the University of Oregon College of Design. At the same time, she said, the average unit of housing was well out of reach for a person making the average wage.
“It’s an incredibly brittle, inaccessible housing market,” Knudson said. In addition to increased funding for mental health and addiction services, “The policy action that we need is to fund the housing our communities need.”
What it will take to turn things aroundMitt Romney offers critique on nation’s divisiveness, foreign policy, value of hard, thankless work of governing
Mitt Romney offers critique on nation’s divisiveness, foreign policy, value of hard, thankless work of governing
What the country needs right now is the emergence of a great unifying leader, a government with all three branches doing their jobs, and friends who stand by us, said Mitt Romney, a former U.S. senator and Republican presidential nominee.
During a wide-ranging campus discussion Monday with Jill Lepore, David Woods Kemper Professor of American History, Romney, J.D./M.B.A. ’75, reflected on the divisiveness of American politics over the last decade, current foreign policy that appears to be turning its back on historical allies, and what it will take to turn things around.
Romney put disillusionment from the effects of income inequality high on his list of the causes for our political polarization.
“A lot of people feel that the American dream is not real for them,” that the country is not delivering what they want or need, said Romney.
“It’s the college kids that are saying, ‘I took out a loan and I’m coming out of college, and I can’t get a job. This is simply not right. This is not fair.’”
Other major factors include the rise of social media and news curation, which has undermined a shared agreement by voters on basic facts; multibillionaires bankrolling and influencing political campaigns; and a party nominating process that often bestows outsize sway on more extreme candidates and ideas, he said.
Romney said adding to the dysfunction is the fact that in recent decades legislators of both parties have largely surrendered their independence, in turn, to line up behind their president in partisan fashion.
He also noted that there is the perception of a more partisan swing in the judiciary. He blames that on the parties switching to a simple majority vote in the Senate to confirm judges, abandoning the tougher 60-vote threshold.
So now, he said, when a court decision appears to go against one party or the other, more people assume it was politically motivated, undermining trust in the judicial system.
Romney was a longtime Trump critic who spoke out against him during the 2016 Republican primary and later during his time as a senator, until he left in 2025.
On Monday, Romney made it clear that he approved of some of the things President Trump has done in his second term, such as securing the U.S. border to illegal immigration, while other moves, like getting Europe to contribute more to its own defense, were positions he understood while disagreeing with the president’s approach.
A third set of actions, however, “don’t make any sense,” like starting a beef with Canada, the largest importer of U.S. goods, or alienating European allies over threats to Greenland, he said.
With China and the U.S. battling for global dominance, the country should take advantage of its historically strong relationships with other nations, said Romney.
“I think you want more friends, more collaboration, more coordination,” he said. “I want to be able to say to China, ‘Unless you play by these economic rules, none of us are going to allow your goods to come into our country. Not just America; none of us.’”
Romney, who was governor of heavily Democratic Massachusetts from 2003-2007, said economic issues are important, but perhaps even more decisive for voters are cultural ones.
He critiqued Democrats, saying they have made some mistakes that cost them support in recent years, like the party’s “open border” immigration policy and vocal support for trans athletes.
“My advice is 1) get people who can speak to working-class Americans and 2) make sure that you’re attuned to the cultural issues, not just the ‘Here’s how much more money you’re going to get if you vote for my party,’” he said.
As for the future, Romney said he is “optimistic” and has “faith in America. I’m convinced that our best days are ahead, but we’re going to face some challenges to get there.”
Addressing those challenges effectively will require either the emergence of a great leader, a crisis that jolts the country into unified action, or a new generation that rises up to say enough, he said.
“The reason I come and speak at a place like this is because you guys have the capacity to make a difference and to tell people the truth and to get involved in politics because you want to do something, as opposed to you just want to be there.”
Romney waved off politicians today who seem more interested in podcasting or making viral TikTok videos than in the tough and unglamorous work of governing.
“We don’t need more performers in Washington. If you want to be a performer, go into pro wrestling,” he said. “But if you want to do something, come on in, the water’s fine.”
Psychedelics and the search for truthLegal scholar sees common interests with law, religion, humanities

Universities and psychedelic experiences have something in common, argues Noah Feldman: They can act as an aid in the pursuit of the truth.
In a keynote speech at the Psychedelic Intersections Conference at the Harvard Divinity School last week, Feldman, Arthur Kingsley Porter University Professor at Harvard Law School, proposed that scholars in three academic disciplines — law, religion, and the humanities — could benefit from engaging with the study of psychedelics, although he left aside the question of whether to partake in them.
He began his talk by laying out the resistance facing such an academic alliance — “because the diagnosis is necessary in order to prescribe the cure,” he said.
In the U.S., most psychedelics are classified by the DEA as Schedule I substances. Despite early evidence suggesting therapeutic benefits for anxiety, depression, and other mental health conditions, medical research remains heavily restricted.
Advocates have pursued exemptions to study and consume psychedelics on the grounds of religious liberty, Feldman explained. But, “The law doesn’t want to give out too many get-out-of-jail-free cards, because otherwise it wouldn’t be the law anymore.”
Other advocates have argued that bans on psychedelic use impinge on cognitive liberty: the freedom to alter one’s brain chemistry. Understandably, Feldman said, legal scholars worry about the consequences of that line of reasoning. The humanistic and spiritual study of psychedelics also remains taboo, he said.
To get around those barriers, Feldman posed a twofold diagnostic question: “No. 1: ‘What is a university good for?’ And No. 2, ‘What are psychedelics good for?’ And I’ll refine that to ‘What is psychedelic experience good for?’”
To answer his first question, Feldman turned to Harvard’s motto, Veritas. “The University is good for the pursuit of truth,” he said.
And to answer his second: “I think it’s plausible to say that psychedelic experience is also good for the pursuit of truth — not a single truth, but many different avenues and roots that seek experience that is in some sense interested in the truth.”
Feldman, who is the founding director of the Julis-Rabinowitz Program on Jewish and Israeli Law at HLS, pointed to medieval Islamic philosophers who believed that prophecy was the exercise of the imaginative faculty, and imaginative faculty is what allows you to imagine something truer than what is merely visible.
“We might think of psychedelic experience as an exercise of the human imaginative faculty,” Feldman said. “And perhaps equally important, it’s something that could be translated into the languages of law, religion, and the humanities,” to overcome those disciplines’ resistance.
“We might think of psychedelic experience as an exercise of the human imaginative faculty.”
Feldman pointed to a paper from Columbia Law School scholars Jeremy Kessler and David Pozen that framed psychedelic experience not as an issue of religious or cognitive liberty but of epistemic discovery: the right to acquire knowledge.
The law, he said, “does have some independent commitment to the idea of getting at the truth,” as do religion and the humanities.
“A humanistic account of psychedelic experience will take as its raw material not only the phenomenology, from phenomenological reports that people make, but also, and maybe even more importantly, the products of culture themselves that engage with the philosophical and literary and historical questions of the nature of consciousness and its relationship to reality.”
The questions raised by psychedelics, Feldman continued, are all the more relevant in the age of artificial intelligence.
“In the history of our imaginings about intelligences that are nonhuman, every time we imagined a nonhuman intelligence that could speak, we assumed it would be conscious,” Feldman said, citing C-3PO of “Star Wars” and HAL 9000 of “2001: A Space Odyssey.”
“The philosophical inquiry and the humanistic inquiry more broadly into the nature of consciousness — namely, what is it like to be us? And why does that matter? — is the single most pressing philosophical question we have. And what do you know? It’s the same question that we have to ask in relationship to the experiences of consciousness that we associate with psychedelic experience. So far from being peripheral to the humanities, the questions of consciousness, the meaning of experience, the possibility of experience, and the nature of the real in relationship to sense data are at the beating heart of the humanistic endeavor.”
Feldman closed by saying he felt optimistic about the future of the law, religion, and the humanities engaging with the study of psychedelics under their shared interest in the pursuit of truth.
“The pursuit of truth is a tool for making life better, if we believe that truth is good for us,” he said, “and I do.”

In podcast, experts break down ‘biological contradiction’ of a 65-year-old with the memory of a 25-year-old — and what that means for the rest of us
Aging is inevitable. Aging well? Not so much. Yet some older adults, known as “super-agers,” retain the cognitive sharpness of people decades younger. Understanding what sets super-agers apart could be key to unlocking benefits for the rest of us, say researchers.
“Super-agers are a biological contradiction. They are over 65 years old, but they have really maintained a brain with youthful characteristics,” said Alexandra Touroutoglou, Harvard Medical School associate professor of neurology and director of imaging operations at the Frontotemporal Disorders Unit at Mass General Hospital.
In this episode of “Harvard Thinking,” host Samantha Laine Perfas asked experts what they’re learning from studying these exceptional agers. Along with Touroutoglou, she was joined by William Mair, a professor of molecular metabolism and the director of the Healthy Aging Initiative at the Harvard T.H. Chan School of Public Health, and Suzanne Salamon, Harvard Medical School assistant professor in medicine and clinical chief of gerontology at Beth Israel Deaconess Medical Center.
William Mair: I think that for a long time, humans saw aging as just this inevitable consequence, that our bodies break down like machines, that this is a kind of innate pace that you are given when you are born and there’s nothing we can do about it. But we know that the rate at which our bodies age is variable between individuals. And not only is it variable: It’s malleable.
Samantha Laine Perfas: It is natural that our brains and bodies atrophy with age. But some adults, those known as super-agers, have shown that we may be able to keep the sharpness of someone decades younger, even matching the cognitive abilities of a person in their 20s. We’re finding that super-agers’ brains are different from those of their peers, leading them to age exceptionally well. What is it that sets them apart?
Welcome to “Harvard Thinking,” a podcast where the life of the mind meets everyday life. Today I’m joined by:
Mair: My name’s Will Mair. I’m a professor of molecular metabolism. I’m also the director of the Healthy Aging Initiative at the Chan School of Public Health.
Laine Perfas: He runs a lab that studies the biology of aging with a focus on trying to understand why cells and tissues age. Then:
Alexandra Touroutoglou: I am Alexandra Touroutoglou, associate professor of neurology at Harvard Medical School.
Laine Perfas: She’s also the director of imaging operations at the Frontotemporal Dementia Unit at Mass General Hospital and runs clinical trials attempting to improve cognitive symptoms in Alzheimer’s patients. And finally:
Suzanne Salamon: Suzanne Salamon. I’m an assistant professor at Harvard Medical School.
Laine Perfas: She’s a geriatric doctor with patients ranging from age 55 to 110. Locally, she serves on the board of the Brookline Senior Center.
And I’m your host, Samantha Laine Perfas. I’m a writer for The Harvard Gazette. Today we’ll talk about what we’ve learned about super-agers and the secrets that may help us all extend and enrich our later years.
It is normal for our brains to atrophy as we age, but for some people, the so-called super-agers, they seem to avoid it. What is it that sets them apart from their peers?
Touroutoglou: Super-agers is an interesting phenomenon because, as you say, they are a biological contradiction. They are over 65 years old, but they have really maintained a brain with youthful characteristics. And because of that, their memory does not decline. They perform as well as young adults in their 20s. This means that while the general thinking is that memory declines and brain functions slow as we age, the studies on super-agers suggest that this is not inevitable and that there may be ways to maintain high levels of cognitive function for much longer in life.
“It is really what we found in their brains that has been so earth-shattering for us.”
Mair: I’d love to pick up on something you said, Alexandra, about the inevitability of aging. I think that for a long time, humans saw aging as just this inevitable consequence, that our bodies break down like machines, that this is a kind of innate pace that you are given when you are born and there’s nothing we can do about it. But we know that the rate at which our bodies age is variable between individuals. And not only is it variable: It’s malleable. In the last 25 years, the field of biology has developed quite sophisticated tools to measure molecularly the rate of biological aging. Those tools have shown us that not only is there variation between human individuals in the way their bodies age, but also that some things we do can really modulate the rate at which people age. And so we can understand now increasingly the biology of those exceptional agers, what makes them different, and begin to work out ways to apply that to the rest of us who are less fortunate.
Salamon: The super-agers, the people who are maintaining their youthful ability to remember things and to be social, they still have the same medical issues as people who aren’t super-agers. I have several people in their 90s, and even the super-agers get arthritis, they get back pain, they get spinal stenosis, they have heart disease. And so I think, what Will was saying is, we really need to look at is not only the brains of the super-agers to figure out what keeps their brains sharp, but also in general how to keep everybody’s body sharp with things that have been shown to keep people healthier.
Laine Perfas: I definitely want to get into some of the things we can do to perhaps join that super-ager demographic. But before we do that, I wanted to talk a little bit more about the differences that we see between super-agers and non-super-agers, both in cognitive function but also physical differences.
Touroutoglou: If you were to ask me what is a super-ager compared to a typical older adult, I would say a youthful brain in someone who is 65 years old or older. It’s really what we found in their brains that has been so earth-shattering for us. Our first findings, published in 2016, helped shed light on what was so special about their brains. Our team measured the size of every region in the brain. We found that super-agers had more volume in areas of the brain that are important for memory, most notably the hippocampus. And in some cases, we saw that they had the same size as they are in young adults in their 20s. And our next question was, how well connected are the brains of super-agers? That was the next logical step for us to understand, because we know that no brain region is an island. What we found was that super-agers show stronger connections in brain circuits compared to their peers. And, when we looked closer to better understand how their brains activated when they were actually performing a memory task, we found that they approached memory differently. It seems that they are likely to use more effective strategies rather than just relying on raw memory ability. It’s not that they’re working harder necessarily; they’re just working smarter. We know that in real life, unexpected health events can happen that can accelerate cognitive decline. And that brought us to another study where we focused on surgery. And what we found was that super-agers were more resilient in developing cognitive side effects or delirium after surgery under general anesthesia. So none of the super-agers developed these cognitive complications. Another more surprising finding was that a brain region known as the mid-cingulate cortex was larger in super-agers, and actually the same as that of young adults. And this is particularly interesting because the mid-cingulate cortex is traditionally understood to have to do more with motivation than memory. So some have argued that this region supports tenacity, persistence, grit in the face of difficult tasks.
Salamon: That is fascinating because I will tell you, your observation about general surgery and anesthesia is something that we see so frequently in the hospital at Beth Israel Deaconess. Our geriatric service does many consults on the surgical service, and we are frequently called for, as you said, delirium, which is confusion that happens often when people are in the hospital and often right after surgery. And we find that people who come in with a little bit of cognitive decline already, once they have general surgery and anesthesia, they frequently have dropped a level in their ability to function in the world that frequently never comes back quite to the baseline that they went into the hospital with.
Mair: I think this is also cool, also to get to this fundamental question, Samantha — to become a super-ager, are you a super-ager in your brain and not in your body? Could you be a super-ager for your skeletal muscle, but not your brain? And therefore are we aging — are different parts of our body in different cognitive outputs and different functional outputs, aging at the same rate or different ones? And how do we get to that? Because that question is central if we’re going to ask, how do we all benefit. And I think increasingly those questions are beginning to be studied. So when we talk about those kind of biological aging clocks, which have an increasing level of sophistication, more recently, we can use things like proteomics from plasma samples to assess from one sample the rate of aging from different tissues — because you can see that those proteins come from specific tissues, and you can use those as a way to gauge aging across a body. And in some of those examples, you can show that actually different tissues do age at different rates in a system, and that this might be different for different individuals. I’d love to know from the experts here about whether you think that these exceptional agers, cognitively — is it true that all of them are outliers in cognitive performance, but not in other areas? Is it some are aging across the board more generally well than others? And how do you think about those interventions?
Laine Perfas: It makes me think of something Alexandra said: When you look at the brain regions of super-agers, no area of the brain is an island. Which does get me to my next question, which perhaps Will, this would be a good one for you, but I am curious about what we know about the biology of aging at the cellular level?
Mair: I think that really gets to the difference between describing how aging manifests at a cellular level and then what those causes of aging are and how we can modulate them. And over the course of the last 20 years, we have coalesced around these hallmarks of aging, which describe various cellular functions, from DNA damage to telomere shortening to metabolic dysfunction — there are about 12 of them at this point — which kind of all go wrong with time, and they can lead to different defects. What is important for this conversation is the extent to which those detrimental effects that we see with time on biological function, they impact different tissues and cells differently. So what’s going to cause a disease in the brain, where many of the cells are non-dividing and they have to last your lifetime, will be different than what drives aging in a very proliferative tissue, for instance. But what’s really interesting is we are beginning to realize now, when you think about this interconnectedness, that there are single interventions that we can do, which can modulate all of these hallmarks at the same time. So we know this really well in animal models in the lab, that we can take an animal which ages very badly — whether it’s a nematode worm that lives and dies in two weeks, or a mouse that lives and dies in two years — and we can do one intervention, whether it’s dietary, genetic mutations, or now drugs that completely slow the rate at which those animals age. They live longer, but they also have delayed onset of all those age-related diseases. So you can affect all hallmarks at the same time. And those interventions now are moving through towards clinical trials for humans to see if they can benefit age-related conditions.
But on the other hand, while we wait for those cellular moonshots to come to fruition, we know there are things we can do now, things that describe and are linked to exceptional agers in human populations — whether that’s social engagement, optimism, nutrition, good sleep, low stress, exercise, of course, the things your grandmother told you to do. Increasingly we know that those do have an effect on the whole way the system ages and so we can begin to take a precision approach to apply those things. I think what’s really fascinating is that anything that makes a human age better, whether that is social engagement or optimism or yoga or good diet, does something to the biology and ultimately affects all those hallmarks in the same way. And so these are interventions we can apply across the board, and they’re competing. There is no point in taking some supplement that you read about on Instagram to treat your aging properly if you are sleeping four hours a night, really stressed, eating a poor diet, all those other things. And so there are many things that cause the body to age, and they all go wrong at the same time. Almost anything in biology is worse in an old individual than a young one. But what’s really exciting is now we know a lot about how we can target those things all at the same time.
Salamon: You know what’s really fascinating about what you just said? We are talking about older people who have sharp brains, but bodies who still have diseases. And I am now dealing with somebody in an assisted living facility who’s in his mid-60s. He’s very young, ran marathons all his life, is extremely physically fit, but has early dementia, which is horrible. And it’s a fascinating thing to know: Why does one part of the body age so differently than another part of the body?
Mair: In the era of moving towards precision medicine and precision biology, really, understanding the difference between individuals is really where the answer lies, right? We can increasingly have tools now at a much more scalable and affordable level to understand on a case-by-case basis what makes someone different from others, and to study that molecular level.
I think for a long time, one of the problems with translating bench research, foundational science research, is that we are taught to reduce all the heterogeneity, all the differences, right? To do a good experiment, you want to keep everything the same and change one thing. But as soon as you try to scale that to an individual, to a human therapeutic, or put it through clinical trials, humans are very different, right? So now we increasingly need to get the answers from those differences, and use tools like AI and machine learning to really understand for an individual like that, what is it that makes that person suffer differently from someone else, to respond to an intervention differently?
Laine Perfas: Thinking about Suzanne’s patient that ran marathons his whole life, I would imagine lived a very healthy lifestyle, very physical, very challenging, that required a lot of resilience and grit, and yet is experiencing cognitive decline at a fairly young age. You are all scientists, so you are probably going to hate my question, but it makes me wonder if some people are just lucky.
Mair: So I’m happy to answer that first. Luck — or the scientific word for luck is stochasticity, right? This is just stochastic effects. This is just chance: I tend to think it’s just science we don’t understand yet. I think it is clear that for exceptional agers or for those who are aging more poorly, it is not down to one thing. We can’t define that it’s due to just genetics or one thing in their environment, which makes them separate from everybody else. I do think biological systems are an interaction between genes and the environment, and it’s a very complicated environment. The environment can be things that you do to yourself, things that are done to you, your psychosocial outlook. And we are only beginning to get to a stage now in biology where we integrate these different disciplines. So for instance, I talked about the Healthy Aging Initiative we’re doing at the School of Public Health. We are trying to bring together social behavioral scientists who are working on why optimism makes some people age better in social integration and study the biological mechanisms of that. So many of these things, which I think we do put down to luck quite rightly, really, we don’t quite understand what gives them that luck. I think a classic example is the woman who lived the longest of any human smoked until she was 110. And you can find things, which they all put their luck down to. They’re sure they aged well because they ate a pound of butter a day, or they were optimistic and they did these things. That’s not really science, right? That’s N-of-1 science and we can’t do it. But we are at a stage now where I think we can begin to at least understand on a more global scale what ties these folks together.
Touroutoglou: From the super-aging studies, we’ve known that no particular lifestyle was conducive to super-aging. Some super-agers appear to follow all conceivable recommendations for a healthy life. Others did not eat well, enjoyed smoking or drinking. As Suzanne said, some super-agers also did not seem to be medically healthier than their peers. We have known from some studies that they have similar medication regimens. But what set them apart was what Will said. The group was particularly sociable. They tended to report more friends and family connections. That was the only thing that was common among all super-agers.
Laine Perfas: So let’s talk now about some of the things that seem to slow down our biological aging. All of you have mentioned relationships. So let’s talk about those a little bit, but then also talk about some of the other things that we’ve learned from looking at super-agers.
Mair: This is slightly outside what my lab studies, but we have folks at my school, including people like Professor Laura Kubzansky, who study human populations and study things like optimism, social engagement, and even the act of giving as opposed to receiving in the world is really linked to healthy aging and how our bodies age. We increasingly know a lot about these more generalized behaviors that involve being part of community, that really are — these are epidemiological studies, so it’s always about trying to understand causation versus correlation, but increasingly we can study at the biology level how those different ways we behave can change our body age. These are things that we can begin to change. It’s hard to just turn a pessimist into an optimist, right? That’s a difficult thing to do. Just say, just be different. But at the same time, increasingly, if we can understand the effects on people of social disengagement, of those negative things, the effect we are maybe having through social media, these things that are driving disconnectedness among people, and studying, can getting connectedness through remote means, can that replace human-to-human interactions? These are increasingly things which we can study at a scientific level. I think that’s a real frontier, which we are just beginning to explore now in really incredible ways.
Salamon: That’s so important because so many older people live alone and feel isolated, and it would be interesting to know if they do FaceTime more now that we have all the gadgets. It does seem to me that is very helpful, when people call on the phone. There’s a lot of push to have people age in place, stay in their homes forever, but it’s not really clear that is the best thing for people.
“In the last 25 years, the field of biology has developed quite sophisticated tools to measure molecularly the rate of biological aging. Those tools have shown us that not only is there variation between human individuals on the way their bodies age, but also that some things we do can really modulate the rate at which people age.”
Laine Perfas: Suzanne, since you work directly with patients that are in this demographic, I’d love to hear you talk a little bit about what you have seen be successful for people.
Salamon: One thing that I have seen a lot are what I mentioned before, people who are living in their own homes, homes that they’ve lived in for 40, 50 years, that they don’t want to leave, and usually they get pushed by their kids or by social workers or someone to move into a place where there are other people around. They’re building a lot of these continuing-care communities where they have independent and assisted living and memory care for people who need it. And I have yet to see a single person who regretted moving. They go kicking and screaming, and then once they’re there, they … I’m trying to think of even one who didn’t love it ultimately. Anybody who moves to a new place, it takes a little getting used to, but most of these places offer you your privacy or a whole range of interesting things. So I would say that in our society, if we had more of these kinds of places that were affordable so that people could move into them, I think that’s huge.
My mother, who was living independently until she was 97, and I always thought of her as a super-ager, she fell and broke her pelvis when she was 97. She came up to Boston and was going to move. We rented a place for her in a building, very independent, but it was right at the beginning of COVID. And so we took her in with us just until COVID passed. So of course she stayed with us for three and a half years. I really learned more about geriatrics during those three years with her. And, I think for her, and I’ve seen this with other people too, living together with family is, for many people, very helpful. Most families can’t do it; they don’t have the space or whatever. But to find a place where there is connection and people have interests that interest them, I think that’s really important.
Laine Perfas: We haven’t talked much about the role of diet and physical activity as you continue to age, because there is the physical health of your body and your skeletal system and your muscular system in addition to the cognitive function. But I also imagine they support each other.
Mair: One of the best investments you can make in your healthy aging and how you’re going to age is maintaining muscle mass and skeletal muscle with time. It’s clear that the links between just maintaining your independence and maintaining that muscle mass with time are really important. And so exercise becomes this overriding thing from the biological sciences of aging perspective. Many of the molecular sensors of exercise are also sensors which, in our cells, sense changes to food. And I think some of the things that we have targeted in more lab-based studies that slow the rate of aging are often those things that are intricately tied with metabolism and fasting and exercise and food. When you’re talking about diet, and I’m not someone who works with nutrition and human studies, but a lot on metabolism and how our bodies sense the food we eat and process that food. I do think that metabolic dysfunction leads to cellular dysfunction. So we are very interested in mechanisms that can maintain our bodies’ and our cells’ capacity to sense the nutrients they’re eating and use them appropriately. So switching burning sugar and burning fat. And some of those things, like intermittent fasting or time-restricted feeding, which you may have heard about, they get a lot of public attention: when you eat during the day and trying to not spend all of your day eating and have periods of fasting in your diet. I think we’re at early stages to really show the effect of those on human aging, but certainly the data and animal models are very compelling. And I do think what’s interesting from my point of view is this idea of circadian alignment; I do think that thinking about circadian rhythm, when we sleep, when we eat, when we exercise, is really something that has a big effect.
Touroutoglou: And I just wanted to add here that today, research suggests that a brain-healthy diet is a heart-healthy diet. Brain function is vulnerable to cardiovascular disease and the impact of conditions such as diabetes. The Mediterranean diet, which emphasizes fruits, vegetables, whole grains, legumes, fish, and other seafood, has shown benefits.
Mair: And the flip side of this is when we think about obesity as a risk factor for disease, right? We know increasingly now that obesity is not just a driver for Type 2 diabetes, but also nearly every chronic condition of old age that the obese patients are at risk for: Alzheimer’s disease, cancer earlier, all these sorts of things. In many ways, there are outliers to that, but you can see obesity as kind of an accelerated aging phenotype, which also begins to explain some of these links between BMI and exercise and healthy aging, and some of these side effects that are coming out by things like GLP-1 agonists. There’s a real commonality between healthy metabolism and metabolic function, and many of these different outcomes and chronic diseases of aging, which leads to things like exercise being one of the few things we can really do right now to have an effect on early cognitive decline.
Laine Perfas: I think sometimes with older populations, the advice given is when you get to your later years, slow down, take it easy, relax in retirement. What do you all think of that advice?
Mair: I think it’s balance, right? Slowing down and just taking it easy is maybe not the best advice if that means that you are sedentary and you’re not maintaining your muscle mass. But also we shouldn’t push people to be perfect the whole time. I think there is now also this flip side of this kind of longevity culture we’re in right now, in many ways. It’s this idea that you have to completely optimize your body at all times. You have to wake up every day and see how you slept and how your body’s recovered and be perfect, which is its own pressure, right? And that takes away from these ideas about the mental effects, your mental health on how your body ages. These things are, as we discussed, all connected. So I think there has to be a balance. We have to forgive ourselves for not being perfect. We have to try and understand and meet people where they’re at in terms of what they can do to intervene. But also this sense that it’s never too late actually. And so there are things you can do even really into advanced ages, which can change the trajectory of decline of your body.
Salamon: It seems that no matter how old people are, everybody has some kind of a tracker, whether it’s an Apple watch or a cellphone. I do try to motivate people by showing them the little heart that they can press. But I tell people, regardless of how old you are or want to be, what is important is that you get there healthy without a heart attack or a stroke. And that this can really be helped if you can get a certain number of steps. So you look at how much is your baseline steps, and if it’s 500 steps, try to double it. So to meet people where they’re at, but still to push people a little bit.
Mair: And I think to demystify some of those technologies for older adults, whether it’s those trackers or AI, increasingly, we are moving to a world where we have precision information and lots of data about ourselves. And that can be overwhelming, but it can also be incredible to make good decisions. And finding ways to get that into people’s psyche, who might be afraid of those technologies, helping them to use it to make good choices without feeling they’re a slave to their step number and their sleep score is really important.
“The group was particularly sociable. They tended to report more friends and family connections. That was the only thing that was common among all super-agers.”
Laine Perfas: Learning how to do new things challenges your brain in a healthy way to continue to stay young and nimble. So I was just thinking about listeners who might be like, “Oh, technology, another thing to learn.” It’s like, “Exactly. I think it could be good for you to learn how to use it.”
Mair: Absolutely.
Touroutoglou: Yeah, that’s what I was going to say. Anecdotally, talking with our participants, the super-agers say they really enjoy challenging themselves. They don’t want to sit in the background; they want to learn new things.
Laine Perfas: So if I am someone who’s looking to strengthen and maintain my cognitive abilities and physical function until much later in life, what are some things that I can do that I have agency over?
Salamon: I would say one thing for sure, which Will alluded to, is to stay within the normal weight. Because I agree, I think that being overweight is really a problem for the body, and once you slip into diabetes, that really does affect almost every organ.
Mair: I think one of the most underrated things, although increasingly getting more attention, is sleep and the power of sleep for how we age. Sleep is not just this kind of rest and recovery period. It’s an active process that your brain is using. As we all seek ways to optimize our aging, thinking about sleep, healthy diet, lowering your stress, not having chronic cortisol increases because you’re stressed the whole time, thinking about — maybe, it’s this idea that we used to try and just push to perform and achieve at our work and that meant we sacrifice many other things including spending time with our family, eating well, sleeping, exercising; so really prioritizing these kinds of pillars of healthy living, which really affect how our bodies age. And then I do think there’s real optimism. There are things and technologies coming online in the next 10 to 20 years or maybe sooner around the biology of aging, which will have really incredible effects on preventative medicine.
Touroutoglou: One of the questions we typically get at the clinic is: “How can I become a super-ager?” And in this day and age, we get the question, “How can I avoid the cognitive decline that typically comes with aging? How can I avoid Alzheimer’s disease?” And I’d like to mention a clinical trial that we are currently running at Mass General; our team is using innovative brain imaging techniques to really understand the inner workings from the cooperating brain. We have now identified the features of the super-aging brain that are linked to their youthful function. And we are applying these findings using an innovative technique called non-invasive brain stimulation. And by doing that, we hope to recreate the patterns of resilience that we found in super-agers by promoting neuroplasticity and by strengthening the connections between the neurons in the brain and between the brain regions that we found in super-agers to be related to their sharp memory. I am optimistic that we will be able to delay brain aging and reduce symptoms for Alzheimer’s disease.
Mair: There are things we can do as individuals, but you know, in case there are any policymakers out there, I think we also have to think about inequity in how our bodies age, right? One of the best predictors of healthy aging is wealth and education. And where you are born in Boston will really change the rate at which your body ages. And now, increasingly in the last two years with those molecular measures of biological aging that I talked about, we’ve shown that social inequities drive the rate of aging. And so I think yes, there are things we can do, but also from a public policy perspective, we can really think about what it is that’s leading to some areas of society to age more poorly. And that’s a combination of many of the things that we talked about, why the life expectancy gains that we saw in the last century in this country didn’t occur for all demographics, right? They occurred for different people in different ways, and some people’s life expectancy got worse. So there are things that you can do, but I think there are things we can do together as a community to try and understand why it is that where you are born in many ways, and the luck that life throws at you, to go back to luck, does change how your body ages. And that means that if we solve that problem for the fortunate, we can start to solve it for the less fortunate.

Jayne Anne Phillips recalls childhood visits to beauty shop in rural West Virginia hometown in new memoir
long read
Excerpted from “Small Town Girls: A Writer’s Memoir” by Jayne Anne Phillips, Bunting Fellow (now called Radcliffe Fellows) ’80-’81, by permission of Alfred A. Knopf, a division of Penguin Random House LLC.
Who first tells us what is beautiful? Definitions of beauty are handed down, like stories and myths, absorbed as expressions of a specific time and place. In writing a particular novel, I found myself setting several scenes in a small town beauty shop, similar to one I remember from my own childhood. Beauty shops of that era predated use of the word salon, and there were definitely no male hairdressers. The shops were women-owned and women-operated sanctums in which there were no males of any stripe, unless they were babies, or the loutish teenage sons of the female owners, who walked through purely to rifle the cash register.
Girls need sanctums. It’s probably no accident that a few of the girl characters in my fiction are 11-, 12-, 13-years-old — about the same age I was when my mother began taking me along to her weekly hair appointments. My incursions into the world of beauty were part of my mother’s campaign to get me to cut my long (in her view) scraggly hair, a prospect I continued to view with suspicion, but I grew fascinated with the beauty shop itself. I was invisible there, privy to conversations not usually conducted in my hearing. Lulled by the sounds of the machines, I feasted on trash magazines my mother would never have allowed me to peruse. All around me, women were submitting, being serviced and done to. They engaged in truly archetypal gossip, touching on their own deepest fears and desires, trotting out other people’s stories as parable and warning. Later they got washed. Quiet now, they lay back in their chairs, heads swallowed up by the deep, slotted sinks. I noticed how their legs fell slightly apart. Their hands relaxed. Uniformed girls massaged their scalps with careless efficiency, and the women closed their eyes. Their faces took on a somnolent wistfulness that almost scared me, and I looked away. I’d witnessed attitudes of such surrender only at the movies, in love scenes between men and women, and those, of course, weren’t real.
Women went to the beauty shop to be with other women, to engage in private rituals that supposedly had to do with men, yet the men were wholly absent. They were sometimes discussed, but never as objects of desire, not as the heroes or princes my friends and I expected to encounter, out there somewhere, far beyond the adolescent boys with whom we were forced to contend. Conversations between women here skipped all that and presupposed a middle passage I resisted contemplating. Nowhere in the talk could I detect the dark pulse of promise sex had already acquired for me, a pilgrim at the gates. Women at the beauty shop didn’t talk about sex or refer to their own hopes or traumas. They did talk about instances of seduction, other women who had strayed, but it was always wholly the woman’s story, as though the man and the smell and feel of him were incidental. There were stories of triumph: She finally told him to hit the road. or, I looked him right in the eye and said, ‘There are laws to protect me from men like you.’
Women who came weekly to this shop ranged in age into their 80s, but my mother and her friends must have been in their late 30s. Far younger than I am now, they’d been parents for close to 15 or 20 years and were veterans of what seemed generations of marriage. They referred often to their grandmothers, who seemed to have known one another, too. They knew the stories of those partnerships and misalliances, the childbirths and early deaths, the wayward siblings and how they grew, the musings about those who went away and didn’t come back: They never heard from him again, or, She took those kids and left before he got home from work. The stories presupposed years of friendship between women, nurtured in the shelter of church groups and odd clubs, each with its memberships and little gold pins, its small books of rules, its ceremonies. The society of the shop seemed to me a more egalitarian, less severe adult variation on the theme of girls’ secrets. What happened there became a grown-up version of my first understanding of secrecy — those moments when a favored child of my early life crooked a finger in my direction, whispered, I’ll tell you a secret, and put her mouth to my ear. The words might be indistinguishable from breath itself, from the sweaty hand on my neck, but it didn’t matter. Those secrets bore the scent of our coltish bodies, of weeds and bushes, an earthy smell. In the beauty shop, words did matter, and the smell was chemical. Women didn’t speak in whispers here — they didn’t have to; the story was communal.
Still, beauty shops were a double-edged sanctuary. Here we were initiated into womankind as it existed in our town, but we were also made to understand what hard work it was to be beautiful, or even presentable. How it never came naturally. I remember finally sitting in the chair that pumped up and down with a foot pedal, staring at myself in the mirror. May, the proprietor of the shop, stood on my right, and my mother stood on my left. They debated what to do with me.
Look how short her eyelashes are, May said.
Yes, mused my mother, I’m afraid she’ll always be a plain Jane.
How about a short cut? May said. It’ll help her hair thicken.
And so I emerged, ashamed, my long hair chopped off nearly above my ears, with a haircut called a pixie.
. . .
The painful thing about adolescence is that everything seems absolute, and the painful thing about adulthood is that nothing does. My mother identified with our hometown in every way: comfortable in groups, a housewife who raised three kids while teaching elementary school and taking graduate classes one at a time. Twice, she went to New York with women from her bridge club and saw two or three Broadway shows each trip: “My Fair Lady,” “Brigadoon,” “South Pacific.” She kept all her Playbills and played vinyl albums of show tunes, early in my childhood, on our upright cabinet Victrola, singing along: “I’m gonna wash that man right outa my hair …” She went to Europe with women friends from her church, to Oberammergau, for the German passion play held in a Bavarian town outside Munich. “It’s performed once every 10 years,” she said. “I’d better go now, while I’m healthy.” In her early 20s, she’d nursed her mother through a cancer death. My grandmother died at home, and my mother was so traumatized that she never expected to live a long life.
She was right. The year after my mother died, the college in our hometown, her alma mater, presented me with an honorary doctorate of arts. I’m sure the honor was instigated by my mother’s friends, in her memory, in recognition of my attempt to care for her in those years. Her friends knew how she’d struggled, that she’d lived with me the last year and died far from home. She’d accumulated enough credit hours for a doctorate but never wrote her dissertation. Accepting the degree, I hoped I was completing, in a way, one of several important tasks she’d had to leave undone. Her friends all attended the commencement ceremonies. Many were the same women I had known from years before, when their children were growing up and they met at the beauty shop. I don’t remember any of them bringing their daughters to wait for the hour-plus it took to get their hair done, but my mother was a bit of a pioneer then; in 1970, she became one of the first “respectable” divorced women in the town. Some of the other women in her circle had worked outside the home; most had not. Some were the wives of doctors or dentists or professors, women whose lives she perhaps considered easier than hers in some respects, yet she knew them all well enough to know their sorrows; they were all girlhood friends who had struggled side by side through some of the calamities of their adult lives. That struggle and bond are surely the beauty of women, and every detail is remembered. All the rest is fascinating dross.
Can we forgive women for thinking about beauty? Can we forgive our mothers for hoping we’ll be beautiful? Can we forgive one another for fanning out the hand of cards dealt us by our families, our hometowns, by the cultures in which we all exist? All the suppositions about ideals, about what looks good, about what we’re supposed to do, who we can be?
The summer I was 26, during the painful breakup of a love affair, I went home, fled home, actually, to see my mother. Her only sister was visiting her at the time. My aunt Peg was ill, and seeing her was part of my excuse for leaving the man in question. I’d been driving for 10 hours; I was sweaty and tired, wearing a black leotard and (still) jeans.
Did I tell you? my mother asked my aunt. Someone’s going to publish her book.
No kidding, my aunt mused. As I struggled in and out with my suitcase and bags of books, she asked me, Why is your stomach so flat?
I don’t know, I said.
I do, said my mother. You won’t be asking her that question after she’s had a few babies.
Well, my aunt answered, she looks wonderful. They ought to put her on television right now — it’s all downhill from here.
Thanks, Aunt Peg, I said.
Mark my words, she responded.
And so it was, and wasn’t. The beauty of a beginning is always easiest to appreciate: the start of emotion, the unlined face, the unsullied field of snow. The middle passage — the deepening, the acknowledgment of age, change, banality, and heartbreak — is another matter. These combined to become the atmosphere I remember, the rituals I didn’t understand, those Saturday afternoons in the beauty shop. Silent observer, I watched the women who were trimmed and permed and crimped. Were they there to be beautiful? To fail in some dream of themselves? I think they were there to be together. One afternoon a week in their buffeted lives, someone took care of them.
Philosophy helps us solve ‘big questions that matter,’ argues ‘Justice’ professor as he accepts Berggruen Prize
Samantha Laine Perfas

In 1996, political philosopher Michael Sandel predicted in “Democracy’s Discontent” that globalization would “banish ambiguity, shore up borders, harden the distinction between insiders and outsiders, and promise a politics to ‘take back our culture and take back our country,’ to ‘restore our sovereignty’ with a vengeance.”
Flashing forward to the extreme division we see today, these words have proven prophetic. What were the signs?
“At the time, I thought there was a lot of hubris,” and that legitimate concerns of community erosion were being ignored, Sandel said Monday as he received the Berggruen Prize for Philosophy & Culture, an annual award that recognizes top thinkers whose contributions have lasting intellectual and practical impact worldwide.
He was joined in conversation by Chrystia Freeland, the former deputy prime minister and minister of finance of Canada, who currently serves as economic adviser to the president of Ukraine and is the incoming chief executive officer of the Rhodes Trust.
Sandel, the Anne T. and Robert M. Bass Professor of Government, has written extensively on justice, democracy, bioethics, the moral limits of markets, and meritocracy. An online version of his popular Gen Ed “Justice” course has reached a global audience of tens of millions with lectures covering everything from taxation to free speech.
Sandel debating Ronald Reagan at his high school in 1971.
During the ceremony, Freeland and Sandel looked back on Sandel’s life and career, including his high school years in West Los Angeles. Even as a teenager, Sandel had a knack for challenging conventional wisdom. In 1971, he convinced Ronald Reagan, then governor of California, to debate him at his school — by strategically delivering six pounds of jellybeans to his home. He brought in a legal pad full of his toughest questions on the Vietnam War, the United Nations, and voting rights. Reagan responded respectfully and amiably.
At the end of the hour, Sandel wasn’t quite sure what had happened.
“He hadn’t persuaded us of his views, but he had somehow disarmed us, in part because he took us so seriously,” Sandel said of the experience. “And he listened, which is a lesson that I’ll always remember.”
His most recent book, “The Tyranny of Merit” argues that notions of personal success have led to a deeply polarized society.
“There’s an assumption that has tightened its hold on our public understanding of success, that those who’ve landed on top, that their success is their own doing,” Sandel said.
That’s simply not true, he said. Each of us is surrounded by teachers, family, peers, and environments that play a role in our success. Sandel said we should be cultivating in our youth two messages: work hard to develop talent but also acknowledge the luck you’ve received along the way.
This approach might offer a salve to current political fires, Sandel said. Often elites forget that most U.S. citizens do not have a college education, which many view as the ticket to “dignified work in a decent life.”
“That’s a recipe for anger and resentment, and the sense among many working people is that credentialed elites look down on them, and don’t respect their dignity or the work they do,” he said.
Capping the event, which took place at the Harvard Art Museums, Sandel said he is encouraged by the “hunger” of young people to engage in public debate and noted that philosophy plays a crucial role in our ability to solve problems.
“Many people think that philosophy resides in the heavens far beyond the world in which we live. I think that’s a mistake,” he said. “Philosophy belongs in the city where citizens gather and reason together and argue together about big questions that matter to their lives.”
The $1 million award given annually by the Los Angeles-based Berggruen Institute honors thinkers whose work has made a meaningful impact on a world rapidly transformed by social, technological, political, cultural, and economic change. Past laureates include Onora O’Neill, Martha Nussbaum, Ruth Bader Ginsburg, Paul Farmer, and Patricia Hill Collins.

Garber discusses threat to university-government partnership, AI, fighting bias on campus in talk at 92NY
Is the 21st-century United States sliding toward its own version of post-war European brain drain?
Harvard President Alan Garber said that there are uncomfortable parallels between America today and the era of European history marked by the flight of scientists abroad, particularly to the U.S., a period that damaged the continent as a global scientific power.
Garber’s warning came Monday during a discussion with Wall Street Journal Editor-in-Chief Emma Tucker. The event, “Universities, Democracy, and the American Future,” was held at 92NY in New York and focused on what the turmoil for U.S. universities in recent months means for the nation’s future.
Before the war, Garber said, German was the “lingua franca” of science. Post-war migration to the U.S. was at least part of the reason the nation’s research and discovery leapt ahead in the ensuing decades, he said.
A second reason, he said, was the unique financial partnership that arose between universities and the U.S. government.
In that partnership, the government offered significant financial support for research. Its success put the U.S. at the forefront of global scientific advances for decades, which in turn drew the best and brightest young minds from around the world here in a virtuous cycle.
The government’s recent assault on research universities, however, threatens to unravel that partnership and reverse the flow of talent. Cuts in funding and crackdowns on immigration over the last 15 months have opened the door for other nations to woo young scholars away from U.S. institutions, Garber told an audience of about 200.
“Since World War II, the nation’s universities have been both symbols and drivers of American leadership at home and abroad, engines of discovery, economic growth, and democratic vitality,” said Ken Wallach, a member of the board of directors of 92NY, formerly known as the 92nd Street Y, who introduced the event.
Federal funding is “not a gift. It is a payment for work being conducted at the request of the federal government.”
Alan Garber
“Today, these institutions and that leadership are under real strain, facing political polarization, public skepticism, financial pressures, and technological transformation. It is indeed a moment of profound change and consequence,” he said.
Garber pointed out that other countries have taken note.
“Other nations have looked at this, and they’re seeing opportunity, just as the U.S. did in the leadup to World War II,” he said. “And there are funds in Canada and in Europe to recruit American scientists, and China is doing everything it can to ensure that its most promising scholars who are in the United States go back to China.”
With the conflict over research funding ongoing, Tucker asked whether Harvard should just go it alone and refuse to take federal money.
Garber said that ending the university-government partnership would have wide-ranging implications not just for higher ed but for the nation.
Federal funding is “not a gift. We have to be very clear about that. It is a payment for work being conducted at the request of the federal government,” Garber said. “If we were to say we are not going to conduct research, we’ll give up federal funding, arguably we might be better off financially, but it would cut out a big part of our heart. This is what research universities do. But the damage is not just to the universities, the damage is to the country.”
Garber acknowledged that not all of the criticism from the administration was unfounded.
Antisemitism on campus went unacknowledged for too long, he said, which was confirmed by a task force he appointed.
That body, and a second examining anti-Muslim and anti-Palestinian bias, both reported back on ways to address the issue, through education, including changes to student orientation, better accommodation of religious practices, and rethinking instruction about the topics.
Though the task forces expected it to take years for the reforms to effect change, Garber said they’ve seen meaningful shifts on campus after just a year.
One area with few concrete answers concerns the impact of AI on both education and the world awaiting graduates. Universities will have to keep up with the pace of change, he said, and today’s students will have to adapt as AI transforms the way we work.
Despite all the challenges facing Harvard and other U.S. universities, Garber said he is excited about promising areas of research, such as quantum computing, statistics, and the life sciences, which appear to be on the cusp of major breakthroughs.
“I think our cause is just. I’m excited about what we can accomplish,” Garber said. “This is not about Harvard. It is about higher education, it is about the future of the country. I think we can be on a good path.”
He added: “I want to do my part, and I know the entire Harvard community wants to be part of making this a stronger country and a better world. That’s what keeps me going.”
What makes a good student Inner drive, integrity, open-mindedness among qualities highlighted by faculty
Inner drive, integrity, open-mindedness among qualities highlighted by faculty
Many of us spend years or even decades of our lives as students, and some of us are better at it than others. We asked professors and lecturers from around Harvard University to share the qualities and practices they notice in their best students. Get out a pen and paper: You’ll want to take notes.
Integrity matters
I’ve had the good fortune of working with many wonderful students in my time here. In my experience, the best students have had four qualities.
The first and most important is a genuine, deep, persistent curiosity that extends beyond the student’s core area of study. Curiosity like this is really a love of learning and discovery, in a very broad sense, and it gives students the motivation to keep going even when the material gets difficult, which it always eventually does. This expansive kind of curiosity also helps students make nontrivial connections that can lead to novel insights and breakthroughs.
The second is rigorous thinking, of the kind taught in a serious philosophy course. Students who can formulate their ideas as carefully reasoned arguments, from clearly stated premises to precisely argued conclusions, are not only more likely to understand what they’re doing, identify hidden assumptions, make new discoveries, and avoid making mistakes, but are better at teaching and communicating their ideas to others.
The third is integrity. My best students are honorable. They hold themselves to high moral standards, do their work honestly, and earn the trust and respect of their peers and colleagues. These students don’t cheat or take ethical shortcuts, especially the sorts of ethical shortcuts that don’t seem like a big deal or that seem widespread.
The fourth and last is knowing when what they’ve done is enough. It’s easy for curious, rigorous, honorable students to go down rabbit holes or never manage to finish projects. It’s difficult to develop a sense for when it’s time to conclude a project and move on to the next one — but it’s a crucial skill, and one well worth working on.
— Jacob Barandes, senior preceptor in physics and associated faculty in philosophy in the Faculty of Arts and Sciences
Process-oriented
One of the key skills you need as a medical student is prioritizing information. Often when medical students struggle, they are trying to remember everything. This comes from a place of deep caring, a commitment to their future patients. In these moments I try to talk with the students about the differences in how experts and novices process information. Novices first need to build scaffolding for the new information — they need to focus on the connections and bigger picture — before they can add all the details. Experts can take in details much more quickly. They already have a lot of knowledge to connect the new information with, so it “sticks” with much less effort. Building that scaffolding is hard, slow work, and it may feel like you are missing out in the moment. I encourage students to examine their relative “expert-novice status” on any topic and adapt their study strategies and expectations of themselves accordingly.
— Henrike C. Besche, director of education at the Harvard-MIT Program in Health Sciences and Technology
Drive defines them
The quality I’ve found most consistently in good students is inner drive. They don’t need an external push; they’re motivated by a genuine desire to understand rather than just to perform well on an assignment or exam. That kind of drive is hard to teach, but when it’s there, everything else tends to follow.
“They don’t need an external push; they’re motivated by a genuine desire to understand rather than just to perform well on an assignment or exam.”
Tied to that drive is genuine curiosity. Good students want to know how things work and why. They ask deeper questions and follow threads that go beyond what’s strictly required. That curiosity is what keeps them engaged when the work gets challenging — and in physics, it will get challenging. That’s where perseverance and resiliency become essential.
I like to draw a distinction between what it means to be a good student versus a good learner. I often see kids, even young ones, who have learned what’s expected of them in school and they aim to perform well in that context: They know how to be organized; they have beautiful binders; they get good grades. But too often these kids get to the end of high school, or maybe even college, and they’re asking, “What have I really learned?” Much of what they have learned doesn’t transfer to their lives beyond school.
Good learners, by contrast, are motivated by their passion for finding out. They are willing to take risks and work at “learning edges.” They don’t play it safe; they learn from both their successes and their failures. They’re mastery-oriented, which means they see intelligence as learnable, which it absolutely is. They have a purpose for what they want to do — the changes they want to create in the world — so they’re motivated to develop the skills they need to make those changes. Interestingly, sometimes they have a disregard for what it means to be a “good student” as they make choices in favor of their learning over grades, requirements, tests, etc.
In the work I do at the Next Level Lab, we encourage learners to be agentive, but beyond that, we teach people how to use their agency to leverage their contexts toward their best learning and performance. This includes looking for malleability, where possible, in their social, emotional, technological, cognitive, and physical environments. I have had students physically rearrange their workspaces to support their attention and perception. Often in schools, teachers are the ones creating contexts that are conducive to learning, but it’s the students who need to learn this. They’re not here to please their teachers. They need to do it for themselves.
— Tina Grotzer, faculty and principal research scientist in education at the Harvard Graduate School of Education
The right questions, on repeat
In law, as in the University more generally, we are teaching students to think about the world in a different way than they have before. We are teaching methods, perspectives, and techniques in addition to imparting detailed knowledge. The good students ask questions — and keep asking them. They see a phrase in a legal opinion, or hear something the professor has said, and want to know more. They are conscious that no matter how much they know, there are more questions to ask. And they see the project of university learning as not simply the validation of their preexisting political and ideological beliefs, nor the balancing of different ideological or political views in a stilted discussion, but rather, the shifting of one’s perspective. Good students work hard and persevere. They aren’t afraid to come see the professor at the end of class to say they don’t understand something. My students have gone on to be professors, big city mayors, members of Congress. But the ones I remember best, and who have impressed me the most, are the curious ones. They always want to know what they don’t know.
— Kenneth W. Mack, Lawrence D. Biele Professor of Law and affiliate professor of history at Harvard Law School
Seeing what others miss
The qualities I’ve noticed that support success in design begin with a sharpened attention and a willingness to commit to closely reading things in the world. The form of attention that I refer to enables students who possess it to pick up on details that others might miss. The capacity to lock in and sustain a close read of these pickups unfolds new details and questions that can be explored and advanced through iterative thinking, visualizing, and making — the methods of design.
Most importantly, these traits allow the student who wields them to first problem-set, and then to problem-solve — dual actions that define design. First: What is the right question to ask? Followed by: What material, scale, and making technique is best suited to exploring possible solutions to that question?
These traits can be cultivated with knowledge of their power and with practice — things that are regularly taught, talked about, and then put into play in the design studio.
— Megan Panzano, senior director of early design education and lecturer in architecture at the Harvard Graduate School of Design
Deep curiosity
There is an old story in medical education about what the professor tells their students on the first day of class: “Half of what we will be teaching you in the next four years will be found to be wrong in 20 years; the only problem is that we don’t know which half.” While this is probably not unique to medicine, the field continues to evolve at an incredible pace. Given the nature of medical practice, what kind of student do I want? What kind of student will make the best doctor not just on the day they graduate school, but decades later as well?
“What kind of student will make the best doctor not just on the day they graduate school, but decades later as well?”
For me, curiosity is the key ingredient. Curiosity to keep asking questions, to want to know not just what to do, but why one should do that. Curiosity about how things work. Why did the blood pressure fall? Why did the chest pain change? How is this shortness of breath different from what the patient experienced in the past? Not only is curiosity the key to understanding human biology, it is also the key to being a humanistic physician. One needs to be curious about the patient sitting before you. Who are you? What is important to you? How do we make a decision on your care that is consistent with your values?
Mix curiosity with the humility to admit that none of us has all the answers and the determination to always get better at your craft, and you have the right student.
— Richard M. Schwartzstein, Ellen and Melvin Gordon Distinguished Professor of Medicine and Medical Education, Harvard Medical School
Never indifferent
Each student is different, and so are their learning styles and study habits. The hallmark of a good student is a commitment to learning rather than solely achieving high grades. Good students demonstrate critical, analytical, and imaginative thinking. They abhor both laziness and indifference to learning. Such students are organized, prepared, and diligent, and they pay close attention in class. They consider alternative viewpoints while remaining open-minded, and are receptive to feedback without being defensive. Over time, good students develop a growth mindset, fostering healthy curiosity and a desire to acquire new knowledge. They reflect on the significance of mistakes, move beyond them, and extend grace to themselves. Good students recognize preparation and curiosity as essential virtues. They seek assistance promptly and use professors’ office hours effectively. Motivated by setting and achieving learning goals, good students are also good citizens because they contribute positively to the learning environment as responsible members of the academic community.
— Dehlia Umunna, clinical professor of law, Harvard Law School
Up for an argument
A good student is defined by a willingness to engage with perspectives different from their own. In government, we deal with questions that are often contested and rarely settled. The strongest students take disagreement seriously: They listen carefully, try to understand where others are coming from, and respond thoughtfully rather than reactively. They are open to revising their views when the evidence points them in a new direction, while still expressing their own arguments with clarity and respect.

‘Dark Frontier’ author details life in one of Earth’s harshest environments and quest to carve out ‘national parks’ of the oceans

Home to translucent shrimp living in sulfurous vents, methane-eating microbes, and corals older than the Egyptian pyramids, the deep sea is among the Earth’s most extreme environments. It’s also under threat — from climate change, resource extraction, and overfishing, said Jeffrey Marlow, a biologist and the author of the new book “The Dark Frontier: Unlocking the Secrets of the Deep Sea.”
“It’s very easy to destroy these environments, and they take a very long time to come back, if they ever do,” he said.
Marlow, an assistant professor of biology at Boston University, completed postdoctoral research at Harvard’s Girguis Lab, where he researched the strange ways deep-sea microbes sustain themselves in incredibly harsh environments. During that research, he also served as a scientific adviser to the United Nations working group behind the Agreement on Marine Biological Diversity of Areas Beyond National Jurisdiction, commonly known as the High Seas Treaty, which took force this January.
In this interview, edited for length and clarity, Marlow shared what it’s like to venture thousands of meters below sea level, and to bring what he learned there to the halls of international power.
If you’ve got thalassophobia, this research-backed quiz is not for you.
Quiz
What is it like to visit the deep sea in a submersible?
It’s definitely a bizarre experience. On one hand, you’re visiting an enormous realm of geology and biology — all of the processes that occur in the deep sea are grand in scale. But on the other hand, the experience of being there is very small. You’re in this tiny little sphere. The headlights of the submersible only illuminate so much.
But what that does is it draws your focus to the tiny details. You aren’t looking at the huge cliffs around you; you’re looking at these little worms and these rocks with weird things on them, these little gas bubbles that might be coming out. It’s bizarre to be going through so much space to get to a place where perhaps no human has ever been and then focus on the minutia.
What are some of the more unusual creatures who make their homes in the extreme environments of the deep sea?
One of my favorites are the microbes that eat methane at methane seeps. They’re cool for a couple of reasons. Firstly, they turn methane, which is a strong greenhouse gas, into rock, which is just an amazing transformation metabolically, and also obviously important for our greenhouse gas budget. Secondly, they require a symbiosis. The process of using methane as an energy source without oxygen is not energetically possible on its own; it requires other microbes that breathe sulfate, to make up the difference. It’s only through symbiosis that the entire process is possible.
“We’re coming to understand more and more that life is interconnected, especially in extreme environments where there’s barely enough energy to survive on.”
Another of my favorites is a type of microbe called Oceanospirillales, which is also a symbiote. They live inside of Osedax, these fluffy worms that eat whale bones. After the flesh is gone from these whale skeletons, all that’s left are bones that have some juicy lipids deep inside. But they’re hard to get to. These microbes are able to break down some of the really hard molecules of a bone and feed it to the worm.
These are just two examples of deep-sea symbiosis. We’re coming to understand more and more that life is interconnected, especially in extreme environments where there’s barely enough energy to survive on. You often have to partner with another species to get by.
You’ve been involved with efforts to preserve marine biodiversity at the international level. How are you seeing deep-sea environments impacted by humans today?
The most obvious impact is trash, which you’ll find here and there in the deep sea. We’re also starting to see chemical changes. For instance, a study that came out a few years ago compared a type of plankton that was collected during the [1872-1876] Challenger expedition with the same type of plankton today and found that their carbonate shells are up to 76 percent thinner as a direct result of ocean acidification.
Beyond that, we’re seeing humans interact with the deep sea around resource use, both through oil drilling, which isn’t new, and deep-sea mining, which may be ramping up in the coming years. As humans, we tend to see our environment as a place to acquire resources, and the deep sea is kind of the next frontier of that perspective just as much as it is for scientific discovery.
Can you explain a bit about your work on the U.N. High Seas Treaty?
For several years, I’ve served as a co-lead of the Biodiversity Beyond National Jurisdiction working group for the Deep Ocean Stewardship Initiative, an NGO founded by scientists that was granted official access to attend and contribute to the U.N. process.
As a scientist, I felt at times that the process was quite slow. I came to learn that that was by design. They were really aiming for a treaty by consensus: It’s not that everyone is entirely happy with every word of the agreement, but rather that no one is extremely unhappy with it.
What emerged, in my view, is an amazing framework. Everyone in that room agreed, essentially, that the area beyond national jurisdiction is an important realm worthy of regulation and protection. The details are what matter, and they’ll be worked out in the coming years — and will probably always be updated as we learn more, and as we put things into practice and see what works.
The treaty creates a path for the creation of Marine Protected Areas. How will those work, and are there areas you’d like to see protected?
This would be a fundamentally new thing. I’m excited that we as a global community can put some places in the oceans aside for protection in the same way we put aside national parks on land.
“I’m excited that we as a global community can put some places in the oceans aside for protection in the same way we put aside national parks on land.”
I’d really like to see the Lost City hydrothermal vent system in the Atlantic Ocean protected. Most hydrothermal vents are very hot, and they spew acidic and metal-rich fluids into the sea. But the Lost City is different. It’s alkaline, and it’s a little bit cooler. It has some properties that make a compelling analog for where life originated on earth.
There’s also the Sargasso Sea, a big raft of sargassum seaweed that, through the confluence of ocean currents, is rather static in the Mid-Atlantic, off the coast of Bermuda. It has a lot of endemic species that could be at risk from overfishing and pollution.
I’m not an absolutist: We need our materials and resources from somewhere, and there’s likely a world in which getting things from the deep sea is the least impactful way to do it. But there’s still so much we don’t know about these ecosystems. I think there’s value in building a proverbial fence around some parts of our planet as long as we possibly can to preserve nature in its most pristine state.
At a more macro level, the treaty also changed the principles we apply to our engagement with the oceans, is that right?
Yes. Interestingly, what held it up to the very last minute was a debate between the principle of “freedom of the high seas” and the principle of the oceans as the “common heritage of humankind.”
Traditionally, we thought of the seas as a limitless frontier; there was no indication that any of the ocean’s natural resources were going to run out. That framework of the freedom of the high seas made intuitive sense: There was plenty for everyone, so who cares if I go and get what I need?
But as we’ve learned more about the limits and repercussions of resource acquisition, that regime needed to change. The treaty is now guided by both the principle of the common heritage of mankind and by the freedom of the high seas.
We do need a common language and a common framework to use these resources collectively. Whether or not that really happens remains to be seen, but it’s inspiring that the global community came together to come up with something that might chart the path forward.
When Egyptians made blueArt Museums workshop explores 1st synthesized pigment, examines its legacy
Art Museums workshop explores 1st synthesized pigment, examines its legacy
The very earliest pigments, like those used in prehistoric cave paintings, were made from ground-up earth minerals and organic materials like charcoal.
The ancient Egyptians made a major breakthrough in becoming the first to synthesize a pigment, paving the way for the eventual creation of thousands of others, to the delight of artists, manufacturers, hobbyists, and other consumers.
In a recent Materials Lab workshop at Harvard Art Museums, conservators gave a hands-on crash course in creating the first synthetic pigment — known as Egyptian blue — while also exploring its legacy.
Lisa Barro holds a pair of night vision goggles, which allow the viewer to see where Egyptian blue pigment has been used on artworks.
“Pigments are everywhere. You can find them in dry media, like pastels, crayons. They’re in papers, they’re in photographs, they can be in plastics,” said Lisa Barro ’97, an adjunct professor in art history at NYU, who helped lead the workshop. “Egyptian blue was the earliest synthetic pigment, made around 3100 B.C.”
The vibrant blue was the product of advances in Egyptian pyrotechnology that allowed silica, copper, calcium, and sodium salt to be combined at a high heat. It was a cheaper alternative to rare, mined lapis lazuli and went on to become a favorite among artists for centuries.
How can scholars be certain that what they’re looking at is Egyptian blue? During the workshop Barro, along with conservator Carolyn Riccardelli of the Metropolitan Museum of Art, utilized a novel technique known as visible-induced luminescence imaging, or VIL.
This is how it works: Researchers examine a piece illuminated by visible light using a device equipped with infrared detection technology (often an infrared camera or night vision gear). Areas containing Egyptian blue appear to be almost glowing amid the otherwise black-and-white VIL image.
“So if you use a put a special filter on your camera, to block the reflected visible light, you can see this luminescence,” Barro said.
Before VIL imaging was developed by Giovanni Verri in 2007, Barro said, detecting Egyptian blue would require an invasive process of analyzing samples for their unique chemical profile. Egyptian blue has a distinct crystalline structure that differentiates it from other similar materials, such as Egyptian faience.
“Every year, there are new discoveries about Egyptian blue, and our understanding of the chemistry is evolving, and our ability to detect it keeps improving,” she said.
Researchers have also found Egyptian blue to be useful in providing insights into ancient civilizations.
Recently, researchers from MIT made a new discovery in Pompeii that a small blue room preserved by the eruption of Mount Vesuvius in the first century A.D. was actually a fresco wall painted with Egyptian blue.
Scientists were able to calculate the amount of Egyptian blue used on the walls, observe the quality of the decoration, and conclude the home’s owners were likely among Pompeii’s elite.
“When I was here as a student I learned that the end date for using Egyptian blue was around 900 A.D.,” Barro said. “That is not true. With this new imaging technique the dates keep stretching, and we keep finding new samples of Egyptian blue.”
Barro (right) demonstrates working with Egyptian blue pigment.
Also in the last decade, researchers have discovered Egyptian blue in Italian renaissance works — including in Raphael’s Roman frescoes at the Villa Farnesina.
Harvard Art Museums is home to the Forbes Pigment Collection, a collection of historical pigments compiled between about 1910 and 1944 by the director of the Fogg Art Museum. While not open to the general public, the pigments are available to view through the Conservation and Art Materials Encyclopedia Online (CAMEO) database here.
Harvard leaders salute National Security FellowsGarber, Allison, O'Sullivan speak to strong ties between University and military, thank cohort for impact on campus life, students
Garber, Allison, O'Sullivan speak to strong ties between University and military, thank cohort for impact on campus life, students
The enduring connection between Harvard and the U.S. military owes not just to the service of thousands of students and graduates through the decades but also to shared values, President Alan Garber said on Tuesday.
Garber, together with leaders at the Kennedy School and the Belfer Center, spoke at a reception at Loeb House for this year’s National Security Fellows, a dozen active-duty officers holding the ranks of lieutenant colonel, commander, and colonel. The fellows spent the academic year taking classes, leading seminars, and participating in working groups on topics ranging from the future of diplomacy to atomic power and weapons.
“We are very, very deeply connected with the military,” Garber said. “Harvard students and alumni have served going back to King Philip’s War, in 1675, before there was a United States. It’s not only a reflection of the age of Harvard — it’s a reflection of common values. There’s so much we stand for in common, and a lot of it has to do with service and service to the country, which can take many different forms.”
Garber, an M.D. who practiced 25 years in a VA hospital, said that his clinical work exposed him not only to his patients’ experiences, but also to their character.

“It was one of the most meaningful experiences in my life,” he said. “I treated veterans who served during wartime from World War II right up until I left in 2011, and their stories were remarkable. Stories of courage, stories of learning how to work together and what it meant to be part of a team.”
The National Security Fellowships were founded 42 years ago by Graham Allison, Douglas Dillon Professor of Government and former Kennedy School dean, and the late Ernest May. The program is among the School’s earliest executive education initiatives.
“This program is a crown jewel in so many ways, bringing people of accomplishment and experience into our environment, where we hope you learn from us and we certainly learn from you,” Garber said, adding: “I want to thank you for spending your time with us.”
Harvard’s president was joined by Allison and Meghan O’Sullivan, director of the Belfer Center for Science and International Affairs, which hosts the program, in thanking the fellows for their service to the country and for their contributions to the University community since they arrived in the fall. Fellows bring a unique perspective to Harvard, O’Sullivan said.
“We are a place where we value the bridge between practice and ideas and scholarship, and you personify that,” said O’Sullivan, who served as deputy national security adviser during the George W. Bush administration. “We talk a lot about national security, strategy, and grand strategy, and you’ve actually lived it. You’ve made decisions under pressure. When you step into our classrooms or our common rooms, you are bringing a commodity that is highly prized.”
O’Sullivan, the Kirkpatrick Professor of the Practice of International Affairs, said that she routinely asks graduates about the most powerful moments in their time at the Kennedy School, and that they regularly point to interactions with service members.
“More than half of our students are from other countries and they never imagined they would meet somebody in the U.S. military, they never imagined they would become friends with someone in the U.S. military,” she said. “Suddenly, they’re in a position where, when they hear about the U.S. military, they’re going to think of your faces, personifying one of our greatest institutions in a way that is absolutely priceless — for them and for our country.”
Allison noted that Harvard has 18 Medal of Honor recipients, more than any other educational institution outside of the service academies. The names of hundreds of the University’s war dead adorn the walls of Memorial Hall, which records Union soldiers who fell in the Civil War, and Memorial Church, which was built to honor the dead of World War I and now also includes service members who died in World War II, the Korean War, and Vietnam.
Several speakers described the moment as bittersweet, including Eric Rosenbach, director of the fellowship and a senior lecturer of public policy at the Kennedy School. The reception marked the approaching end of the program for current fellows as well as an upcoming pause in bringing new National Security Fellows to campus. The government announced in February that it would end professional military education, fellowship, and certificate programs with Harvard and other Ivy League schools.
Speakers described the change as a hiatus, however, rather than the program’s termination. They also encouraged current fellows to stay in touch, both with one another and with faculty associated with the program. This year’s cohort will join a network of more than 800 National Security Fellows who have come through the program since its start in 1984.
“You are part of our fabric,” O’Sullivan said. “You will be part of our fabric when you leave these doors.”
When is it time to dissent?Legal, constitutional scholar suggests looking to judges’ practices for wider lessons
Legal, constitutional scholar suggests looking to judges’ practices for wider lessons
Liz Mineo
Harvard Staff Writer

Calling this “an age of dissent,” legal and constitutional historian Marco Basile urged aspiring lawyers to learn to deal with the complexities of disagreement in the practice of law and in life.
“Both as lawyers and as persons of faith, not just blind followers, we will inevitably wrestle with questions of whether to disagree and how to do so productively,” said Basile, assistant professor at Boston College Law School, during a talk sponsored by the Catholic Law Students Association at Harvard Law School.
Dissent is inherent to our legal system, but also to faith, said Basile ’08, J.D. ’15, Ph.D. ’16. While law is about disputes and disagreements, faith becomes richer by probing and questioning rather than blindly accepting institutional precepts, he said.
Basile served as a clerk for Justice Ruth Bader Ginsburg on the U.S. Supreme Court and Judges David Barron and Paul Watford on the federal courts of appeals. He urged Basile’s students to look for lessons in both law and religion on how and when to dissent.
“There is a lot we can actually learn from judicial dissent about how to navigate that challenge,” said Basile.
It is done for different reasons and can take various forms, he said. For instance, Justices William Brennan Jr. and Thurgood Marshall dissented in every death penalty case that came before them.
“Normally judges don’t do that,” said Basile, “but in death penalty cases, Brennan and Marshall dissented over and over again. It was a matter of integrity.”
Judges can also manifest their disagreement in hopes of influencing the majority opinion or persuading other institutions of a different view.
An example of that is Justice Ruth B. Ginsburg’s 2007 dissent in Ledbetter v. Goodyear Tire and Rubber Company, he said. In that case, the majority found Title VII of the Civil Rights Act of 1964 imposed a strict 180-day limit for bringing workplace discrimination lawsuits. Ginsburg argued Congress should amend the law as its deadline was too restrictive and unfair.
“Of all her dissents, the one Justice Ginsburg was most proud of is Ledbetter,” said Basile. “She wrote it for Congress. She asked Congress to fix it, and, in that instance, Congress did it like almost immediately.”
When judges dissent, they can also do it in an attempt to correct errors out of concern for the “verdict of history.”
“Sometimes, judges are trying to correct something by writing to the future, to a future generation, or in a very particular sense, for the court of history,” said Basile.
Ultimately, the big question when it comes to dissent is knowing when to do it, said Basile.
Lawyers should be mindful of the costs and consequences in time and resources of taking opposition — and the possibility of being incorrect.
“You might be wrong, and the fact that most of your colleagues disagree with you is often an indication that you might be wrong,” said Basile. “You have to balance powerful reasons for disagreement with some quite serious costs to dissenting.”
A practicing Catholic, Basile said he relies on his faith to decide when to let something slide and when to speak up.
He said he finds inspiration in the story of Nicodemus, a biblical figure who appears in the Gospel of John, as an example of someone who wrestled with doubts and found resolution by confronting them directly without fear or favor.
“We live in an age of dissent and disagreement, and it’s worth asking these big questions,” said Basile. “When it comes to the deeper question of dissent: ‘How do I know what to do?’ I’m inviting you to think of your faith, from whatever tradition, as a really important resource … It can be valuable practice for developing your conscience or your inner life … and enabling you to know when and how to speak up or stay silent or walk out, whether you confront this problem in a law office or a church or a nation.”

Staff Art Show puts hundreds of Harvard staffers’ talents on display

Not all staffers at Harvard get the chance to flex their creative talents as part of their everyday work. So, Harvard launched the annual Staff Art Show in 2020 to give employees a forum for artistic expression. The seventh iteration of the multimedia exhibit displays the work of 215 artists in three locations across campus — Longwood’s Countway Library (through June 5), Cambridge’s Smith Campus Center (through May 4), and Allston’s Harvard Ed Portal Crossings Gallery (April 16-May 14). Here we profile three artists in just a small sample of the talent on display this year.
Curatorial Assistant II, Harvard University Herbaria
“Forest Floor,” botanically dyed fabric, embroidery thread, cyanotypes, and branch
Kaye draws inspiration for her art from her day job at the Herbaria. Harvard’s collection of pressed, dried plant specimens, she stresses, is not only a great resource for research but also for the “historic, beautiful specimens that really cross the boundary between art and science.”
Kaye is currently digitizing the Herbaria’s extensive records of pressed plants, which means she is essentially photographing centuries’ worth of samples to make them accessible to researchers and the public globally.
“Forest Floor” incorporates the skills she’s learned along the way, using cyanotypes — photographic blueprints — of items found during a sojourn in Vermont, such as leaves, flowers, and the wing of a luna moth. To continue the connection with nature, she made subtly colored dyes using such plant material as sumac flowers and onion skins and added embroidery knots to lift the flowers of a yarrow plant off the fabric surface. “I wanted to figure out ways to make it a little more 3D, and I thought using the botanically dyed embroidery thread was an interesting way to do it.”
This is the second Harvard Staff Art Show for Kaye, whose textile art is on view at the Smith Center’s 10th-floor Riverview Commons.
The graduate of New York’s School of Visual Arts said her Harvard job stems — so to speak — from her vocation: “I started using plants in my artwork, and then after graduating I decided I wanted to learn more about plants.”
Looking to “find ways to have an artistic practice that didn’t create a lot of waste,” Kaye settled on using plants and other found material. That has also prompted her in her work toward a master’s degree in sustainability through the Harvard Extension School.
Along the way, Kaye is also planning more textile art inspired by her job, in particular one piece that maps out plant species in Vermont.
“I want to continue to integrate art and science, but this time, bring my own research into it,” she said. “I want viewers to feel connected to nature and reflect on the importance of biodiversity. I also hope this piece highlights the value of using natural and sustainable materials.”
Srinivasan was attracted to art and medicine for similar reasons. In some ways, said the artist, printmaking may have influenced her to choose surgery as a medical specialty.
Linocuts like “Panacea,” as well as the woodblock prints she also creates, involve carving into linoleum to make a plate that is then inked to produce a print.
“Within medicine, I wanted that left-brain, right-brain analytical, problem-solving component that comes with any medical specialty,” said Srinivasan, who studied studio art as an undergraduate and came to medicine through the FlexMed program at the Icahn School of Medicine at Mount Sinai in New York, which encourages creative students to bring their talent to medicine. “But I also really wanted that physical component as well.”
Citing the “state of flow that you find when you’re challenged both intellectually and physically,” Srinivasan explained, “I really love working with my hands, and I wanted something very tactile in medicine. Surgery was exactly that for me.”
The second of Srinivasan’s prints to be shown in a Harvard staff art show, “Panacea” makes visual some of the issues she sees in public health today, particularly what she calls the proliferation of “anti-intellectual and anti-evidenced-based practices.” With a throng of hungry mouths reaching for a spoon of what is labeled apple cider vinegar, she challenges the idea that social media knows better than the medical profession how to treat disease while sympathizing with the desperation of people who have been led to distrust established science.
It’s a topic that came home to her while watching “Apple Cider Vinegar,” a Netflix series about a so-called “wellness influencer” who claimed near-miraculous powers for the kitchen staple. “The idea that apple cider vinegar or any other sort of dietary or wellness activity could cure cancer without the help of evidence-based medical treatment was really infuriating to me,” she said.
“But I also think learning to connect with people emotionally with my artwork has allowed me to be more empathetic and understanding with patients.”
Srinivasan, whose print is on view in the Longwood show, is currently working with the Visual Arts in Healthcare Program at Brigham and Women’s Hospital and pursuing an M.F.A. at Rhode Island School of Design. For this surgeon/printmaker, art and medicine “really do work hand in hand,” she said. “There really isn’t one without the other.
“Working on a wood block or working on a linoleum plate is akin physically to surgical dissection and the operating room,” she said. “But I also think learning to connect with people emotionally with my artwork has allowed me to be more empathetic and understanding with patients.”
Beauty meets utility: ‘Art doesn’t have to sit on a pedestal’
Director of Design and Fabrication Instruction, SEAS
Double cage lamp, metal
First-time Harvard staff art show participant Sekoll knows how to make things. As director of design and fabrication instruction, he teaches students how to create the machinery for their experiments and oversees one of the SEAS machine shops. But the teacher, who has earned a master’s degree from the Academy of Art University, where he primarily concentrated on sculpture, sees the connection to art, such as his elegant Art Deco-like lamp, as essential.
“I like working with my hands,” said Sekoll, whose double cage lamp will be on view in Allston. “I like working with tools and equipment. I’ve loved working in metal my whole life, whether it was jewelry or it was in a machine shop.”
That led him to his current job: “When I was getting my master’s degree, I got really into industrial design,” he said, citing the beauty and precision of the work.
Along the way, he discovered a passion for teaching. “I love passing on the skill sets to the next generation,” he said. “When you see their eyes brighten up and they go, ‘Oh, wow, I just made this,’ and you see how excited they get, I get that same thrill.”
For Sekoll, who also creates metal vessels that require precision measurements to seal correctly, the thrill of learning never ends. “Sometimes I just like to get a piece of metal and start playing around with it,” he said.
These days, he is focusing on how best to use tools such as the machine shop’s 3D printers, a learning process that allows him to explore for both his job and his art: “I’d like to spend a little bit more time developing my own skill sets beyond where I am now.” As he does so, he noted, “You’re learning about the machine, you’re learning new features of the machine, but you’re also making something at the same time.”
For Sekoll, the distinction between what he does during office hours and what he does on his own time is basically nonexistent. His three-piece lamp, for example, is functional. That doesn’t diminish its artistic value.
“I started with fine artwork and then got into more functional work,” he said. “For me, art doesn’t have to sit on a pedestal. Art doesn’t have to be a painting on a wall.”
‘Alcoholic’Term conjures outdated stereotypes about an illness that afflicts 28 million Americans, says expert
Term conjures outdated stereotypes about an illness that afflicts 28 million Americans, says expert
A series about meanings
People just aren’t drinking the way they used to.
“As recently as the late 1990s or early 2000s, 85 percent or more of high school seniors said they drank in the past year. Now that number is down to about 42 percent,” said Kathryn McHugh, a Harvard Medical School associate professor of psychology at McLean Hospital and the director of the McLean Hospital Stress, Anxiety, and Substance Abuse Laboratory. “Those are whopping changes in effectively less than a generation.”
Despite those promising trends, alcohol remains a major public health concern, McHugh said. About 28 million Americans had alcohol use disorder in 2024.
McHugh’s lab focuses on the intersection of substance use and anxiety. She says even as Americans’ relationship to drinking has changed, so has the clinical understanding of alcohol use disorder, or, to use the outdated term, alcoholism.
For the latest installment of “One Word Answer,” we asked McHugh to explain the shifting paradigm that reframes addiction as an illness like any other.
The term “alcoholic” harkens back to an old model of substance use that sees it as a permanent feature of your personality or even a moral weakness. The term was used in the 1950s and ‘60s, in very early diagnostic systems for psychiatric disorders, when we didn’t even have a way of measuring it. Decades of research later, we now have a much better understanding of alcohol problems, how to measure them, and how to treat them effectively.
As our understanding of the illness has evolved, so too has our terminology. Over that time, there’s been a big push away from “alcoholism” as a stigmatizing term that implies the illness is a feature of the person’s identity or personality. Starting in the 1980s, the term was changed to either alcohol abuse or alcohol dependence, and more recently, in 2013, it was changed again to alcohol use disorder.
But that said, there are a lot of people who find it helpful, given the significant impact the disorder has had on their life, to identify as “alcoholic.” It’s an interesting push-pull from the perspective of stigma: We’ve really moved away from the term as a field, but there are some people who find it powerful as individuals.
Historically, there was this idea that once you cross a certain threshold, once you’re “an alcoholic,” abstinence is the only option. But the data just doesn’t support that. There are many different paths.
There are some people who do spend many years in and out of treatment, who spend much of their lives struggling with this illness despite wanting so badly to be sober. And there are people who are able to reduce their alcohol consumption to a lower level where it’s not causing any problems. There are also people who decide to be sober for the rest of their lives and are able to make and sustain that change. One thing researchers are very focused on now is how to personalize treatment to meet the needs of each person and to help them safely reach whatever their goal might be, from reducing harm to fully abstaining from alcohol.
Similarly to how we thought of addiction as a personality trait, there used to be a theory that the type of drug a person used mattered a lot; that if someone was struggling with pain, they might seek out opioids, or if they were struggling with anxiety, they might misuse an anxiety medication or alcohol. But that idea falls apart too, as people often will seek out whatever escape might be available.
Some key variables are distress — how low is their mood, how high is their anxiety? — but also how they interpret that distress. If someone is feeling very intolerant of their anxiety, they’re more likely to want to escape it. It’s that sense of, “I can’t handle this feeling, I need to get rid of it” that can put people down a path towards substance use or even just avoidance of daily activities. That drive for escape can lead people to any number of behaviors that provide a “quick fix,” whether it’s alcohol, other drugs, unhealthy foods, or even phone use or social media. Any of these behaviors can cause problems if they’re relied on too much.
I encourage my patients to be on the lookout for the markers of distress intolerance. If you notice yourself thinking things like, “I can’t handle this; I just don’t want to feel this way anymore,” it’s a good sign you’re in that mode and at risk of making an unhealthy decision to try to escape what you’re feeling.
Practice sitting with distress. You can get better at letting yourself sit with boredom or anxiety or pain or tiredness, especially just by noticing it without judging it and without evaluating it in any way. It’s just, “This is how I’m feeling; I don’t have to do anything about it.” You can think of it as buying yourself time to make a good decision.
I’m encouraged by the new cohort of people who are drinking less, and by the thoughtfulness I see around drinking as just another health behavior we need to be mindful of, like getting enough sleep and getting exercise. But there are still millions of people who suffer from alcohol use disorder, and there are more deaths attributable to alcohol in the U.S. than there are to drug overdose. This is still a major public health issue that harms a lot of people, a lot of families, and still needs a lot of attention.
Expanding the fight against heart diseaseSpecialist welcomes shift to more aggressive recommendations
Specialist welcomes shift to more aggressive recommendations
U.S. medical organizations are looking to reduce deaths caused by heart disease, the nation’s No. 1 killer, with new guidelines that reframe prevention as a lifelong battle that begins with testing in childhood.
The changes were made in clinical practice guidelines issued last month by the American Heart Association, the American College of Cardiology, and several other professional organizations.
In this edited conversation, Romit Bhattacharya, a Harvard Medical School instructor of medicine at Mass General and associate director of the hospital’s Cardiac Lifestyle Program, discusses the relevant science, the potential impact of new treatment thresholds, and more.
How different are these guidelines from the 2018 recommendations?
They’ve done a fantastic job and now integrate the newest data from the last 10 years, incorporating information that cardiologists have been using for some time.
The big changes are the formal integration of coronary artery calcium scoring, the formal integration of polygenic risk scoring, the explicit recommendation for Lp(a) screening, and a more formal involvement of apolipoprotein B as a risk measure. These guidelines also call out special populations that might benefit from additional care: individuals with obesity and diabetes, individuals with chronic kidney disease, individuals with hypertensive disorders of pregnancy and other reproductive risk factors, individuals with high genetic risk, and individuals of high-risk ancestries — including South Asian and Filipino individuals, who are now explicitly named — among other groups. This is an attempt to move toward more holistic care based on an understanding of the risk that most people encounter, and then to address, in a more personalized fashion, groups that are at additional high risk.
Some of these new measures, including Lp(a) and coronary artery calcium, might be unfamiliar to patients. What do they tell us that we didn’t know before?
Apolipoprotein B and Lp(a) are additional types of cholesterol — or ways of measuring cholesterol that help us to refine risk. We’ve discovered that Lp(a) is a cousin of the LDL-C molecule and is atherogenic, meaning it leads to the development of atherosclerosis. It’s about six times stickier than LDL, but thankfully it isn’t very high in most people. Lp(a) is, however, elevated in 20 percent of the population and that elevation causes increased cardiovascular risk. Unfortunately, it’s inherited. You can’t eat healthier to lower it, you can’t exercise it away, or stop smoking to make it go down. But when I check Lp(a), it helps me see when I should lower my treatment thresholds and treat you more aggressively to improve your prevention outcome. We have multiple new therapeutics in clinical trials that will help patients with high Lp(a) reduce their risk. And if I can tell you that you have high Lp(a), then you are empowered to make better decisions about your health — eat better, exercise more, etc.
“If someone is 35 today, I want to know what their arteries are likely to look like at 65, not just in the next decade. ”
Are treatment thresholds lower than they were in the past?
Yes, and the mechanism is worth explaining. The old risk calculator — the pooled cohort equations — was overpredicting risk by roughly 40 to 50 percent for many patients. The new guidelines switch to a better-calibrated tool called the PREVENT calculator, trained on more than 3 million contemporary Americans, and lower the treatment threshold accordingly: the old cutoff was a 5 percent predicted 10-year risk; the new one is 3 percent.
This doesn’t mean that everyone above 3 percent automatically goes on medication — that’s where the conversation starts. Someone who comes in at 4 or 5 percent might find that targeted lifestyle changes — improving their diet, exercising regularly, losing weight, quitting smoking, getting better sleep — bring that number down on their own, without ever needing a pill. That’s actually the ideal outcome. Your doctor will weigh all of this alongside your family history and other test results before recommending treatment.
For an individual patient these numbers can sound abstract, but at a population level, this recalibration matters. And crucially, PREVENT also predicts 30-year risk, which is the time horizon where prevention really pays off. If someone is 35 today, I want to know what their arteries are likely to look like at 65, not just in the next decade. We have the most power to prevent disease if we think about 20 or 30 years, where even moderate interventions can dramatically change the trajectory of someone’s health.
And the guidelines call for testing at a much younger age, right?
Yes. The guidelines now recommend that risk assessment starts at 30 — not 40 or 50 — and that for adults in their 30s with elevated cholesterol and sufficient predicted risk, pharmacotherapy is on the table. That’s a meaningful shift. The Cholesterol Treatment Trialists’ Collaborative — a massive pooled analysis of statin trials — showed that the absolute benefit of lowering LDL accumulates over time, which means earlier treatment translates to a much larger lifetime reduction in risk. The old message was, “You’re in your 20s. Don’t worry about it until you’re 50.” But cardiovascular disease doesn’t work that way. The investments you make early pay the biggest dividends, and by the time you’re 50 or 60, you’re playing catch-up.
Separately from that, in children, these guidelines recommend early testing to improve diagnosis of genetic conditions — like heterozygous familial cholesterolemia, which affects roughly one in 250 people and carries a two- to fourfold higher lifetime risk of heart disease, yet remains undiagnosed in up to 90 percent of those affected. Universal lipid screening is now recommended at ages 9 to 11, and cascade screening — testing close relatives of someone already identified — can start as early as age 2. The window matters because family history alone misses up to half of cases, and the earlier you catch it, the more lifetime risk you can take off the table.
“Close to 80 percent of cardiovascular disease is preventable through lifestyle and behavior change.”
Has the lack of a long-term approach been part of the reason it’s been so hard to knock down cardiovascular disease as a leading killer?
That’s a big element. Close to 80 percent of cardiovascular disease is preventable through lifestyle and behavior change. And these guidelines aren’t just for individuals, they’re for society: municipal governments, federal governments, and policymakers. They should be reading and thinking: “How can I support my population in a way that makes it easy to live this healthy life?” Americans are dealing with so much right now: extra jobs, the gig economy, taking care of kids, etc. I see in my clinic that people are struggling. When I say, “and also exercise two hours a week, and eat this, and cook your food at home” — that’s too much. We should think about how we can support our patients and our colleagues and our friends to make healthy decisions so that they don’t have to read the guidelines to know what to do.
My father had a coronary bypass years ago. How would have these guidelines helped him?
Sometimes we check in on someone’s health and a few months or a few years later, they have a heart attack and say, “I went to my doctor and everything looked good. How could this have happened?” That happens because we used to diagnose coronary artery disease only when someone came in with a heart attack or they had to have a stent or bypass surgery.
Imagine instead if you’re middle age and your doctor says that you may be in the intermediate risk class and suggests a coronary calcium scan to see what your arteries look like. The new guidelines have specified that when there’s any calcium present, you should be treated with preventive medication to lower your heart attack risk. And if calcium starts ticking up, we get aggressive and we treat you as if you’ve already had a heart attack. We want to lower your cholesterol to the floor and improve all your other risk factors. If your father had known about his coronary calcium years before his bypass, he may have been able to be on preventive medications and may never have had the procedure.

Tech, data policy expert says concerns legitimate over rising power rates, water use, environmental issues amid mushrooming growth
Liz Mineo
Harvard Staff Writer

Data centers, which house computer systems that help train AI models, are blanketing the country, a boom fueled by surging interest in AI and state tax breaks.
More than 4,000 are already in operation, mostly in Virginia, Texas, and California, and 3,000 more are being planned or under construction.
Data center developers and tech giants argue the projects benefit communities by creating new jobs and boosting local economic development through increased property tax revenue and future business opportunities. They also note that infrastructure must grow if the nation wants to remain a global AI power.
But publicopposition is mounting over the large water and electricity demands and other strains that data centers, often the size of warehouses, place on communities, according to a recent poll by the Pew Research Center.
In this interview, which has been edited for length and clarity, Ben Green, assistant professor in the University of Michigan School of Information and Public Policy and a faculty associate at the Berkman Klein Center for Internet & Society, discusses the impact of data centers on communities, the factors behind their rapid expansion, and the potential for regulation.
Residents are increasingly pushing back against plans to build data centers in or near their communities. Are their concerns legitimate or exaggerated?
The public broadly is quite negative about data centers. Overall, their concerns are very legitimate.
The public is concerned about rising electricity rates caused by data centers. They are concerned about the enormous water use that data centers require. They’re concerned about public handouts in the form of tax breaks that are going to data center developers, and they’re also aware that data centers don’t bring meaningful economic development, especially in the form of jobs.
I think the public is quite right to be concerned about data centers. My research and other research have shown that these are a bad deal for communities on the local level.
“I think the public is quite right to be concerned about data centers.”
It’s been impressive just how well communities have organized around this, how educated they have gotten about the topic, and how many of these projects they have been able to stop. It’s a sort of David and Goliath fight; local communities are pushing back against some of the wealthiest companies in the world.
Certainly not every effort is successful. Sometimes, the wealth and power of these companies win out. But many data center projects have been blocked by local resistance, and many municipalities have passed moratoria that pause data center development.
How much water and electricity do data centers require on average?
The standard definition of a hyperscale data center is that it is more than 10,000 square feet with more than 5,000 servers. But even that is way below the current standard of the data centers that are being built today.
Just a few miles from where I live in Ann Arbor there is a big project, part of OpenAI’s Stargate Project in Saline Township, Michigan, where the plan is for it to be over 2 million square feet and use 1.4 gigawatts of energy. That is equivalent to the energy use of a million households.
What is important here is not just the scale of an individual data center, but also the number of data centers that are being developed at rapid pace across the country, which is fueling a massive expansion in energy and water demand.
Estimates suggest that within a couple of years, the electricity needed for data centers is going to be around 10 to 15 percent of total nationwide electricity demand. This means that the data center boom is putting severe strain on efforts to move the country toward renewable energy sources, often by prolonging the use of fossil fuel plants that had been slated for closure.
Data center developers claim they bring jobs to local communities. What’s your take on that?
It’s a significant false promise of these data centers. Developers say this because they know that it is attractive to policymakers; they come asking the state to give them benefits in the form of tax breaks, reduced regulations, or special zoning permissions in exchange for job creation.
That also allows data center developers to play into this idea of spreading the aura of the tech economy and Silicon Valley across the country by saying, “We can bring a taste of Silicon Valley to Michigan or Ohio or Colorado.”
“It’s a significant false promise of these data centers.”
In practice, this is not what happens. The construction of data centers requires work because these are large construction projects, but that lasts a year or two; sometimes that labor is local and unionized, and sometimes that labor is trade professionals who come in from other states.
Once the data center is up and running, it requires very few people, often just 20 to 50 staff members, because it’s not an office for software developers, product managers, or marketing experts. It is a warehouse of servers.
Do tax revenues and other community benefits outweigh the downsides of data center expansion?
Unfortunately, there’s just very little economic development that plays out on the local level.
There is some tax revenue, but even that is reduced because of tax break policies. Over the last year, Virginia and Georgia have given up more than a billion dollars’ worth of revenue as a result of tax breaks. That’s money that is being handed back to the industry rather than going into public funds that could pay for infrastructure, schools, or healthcare.
Also, there are not beneficial ripple effects like you might see with other industries. Living within a stone’s throw of a data center does not mean that you are getting better or faster or cheaper access to these technologies.
Communities in both blue and red states have pushed back against data centers. Why is this an issue that unites communities regardless of their political leanings?
Data centers are becoming an important issue in local, state, and potentially federal elections because it is an important subject for voters. They can really feel how data centers affect their lives in ways that are tangible and concrete.
And it’s causing some interesting realignments and potential for bipartisan coalitions because it’s not a simple left or right issue. Liberals and people on the left are concerned for environmental reasons and distrust in AI companies, but many conservatives are upset about data centers too.
This introduces a sort of wild-card effect into future elections where being critical of data centers is a big winning issue for candidates. That played out in November in some Virginia and Georgia elections and is a hot topic for candidates campaigning right now, such as in the Michigan Senate primaries.
What policy recommendations are needed to address the expansion of data centers?
Regulation is definitely necessary. One important action is to repeal tax breaks for data center developers because they are incentivizing further data center development and are making it a further bad deal for communities.
A large number of projects are happening because states have passed tax breaks to incentivize data center development. About 35 states now have these tax breaks in place as part of their recruitment pitch.
There are many other considerations.
First, transparency needs to be a bare minimum requirement. There’s an amazing amount of obscurity in data center development right now. Contracts are secretive, and when they are made public, there are huge redactions, and policymakers are signing nondisclosure agreements. There should be early and consistent transparency about what’s being proposed and what the terms of these deals are.
There should be rate protections for consumers with clear contract provisions such that the cost of upgrading the utility infrastructure to service a hyperscale data center doesn’t get passed on to consumers like you and me, which has been happening consistently across the country.
If you live near data centers, your electricity bills are going up, often by a factor of two or more. There should also be a stronger voice for communities in determining whether to welcome data centers, and under what conditions.
One final piece is the need to think about broader planning on how much total water and electricity demand from data centers a state or a region or utility jurisdiction can handle. It’s one thing to say that a state can handle one hyperscale data center, but quite another for that state to be welcoming dozens of such facilities.
We have to make sure that we’re not sacrificing climate goals just for the sake of building more data centers or building data centers faster. We should not be allowing the desire among the tech industry for rapid data center development to push renewable energy goals to the wayside.
How forgiving can improve well-beingNew study of residents of 22 nations finds psychological, pro-social, character changes
They found a connection between regular acts of forgiveness and a rise in the sense of psychological, more than physical, well-being and pro-social and character changes.
“We did find evidence of psychological effects, like happiness, and mental-health-related things like depression,” said Richard Cowden, an IQSS research scientist and lead author of the study. “But we also found, in some cases, stronger associations for character and pro-social behavior outcomes like gratitude and an orientation to promote good. I thought that was interesting: Forgiveness is a pathway to building character and other aspects of one’s volitional life.”
The work was published in January in the journal npj | Mental Health Research and builds on results from the program’s initial survey, released in 2024, which examined the distribution of forgiveness in those nations, which represent between 50 percent and 60 percent of the global population.
The first survey established baseline values for the survey nations and included questions about childhood to illuminate predictors of forgiveness. The second wave, conducted a year later, allows researchers to examine potential effects over time, Cowden said.
The survey was designed to evaluate levels of forgiveness as a practice and personal characteristic rather than a single discrete act, asking, “How often have you forgiven those who have hurt you?”
“I would characterize this as a measure of dispositional forgivingness, which is the tendency to forgive others across time and situations, the habitual practice of forgiveness,” Cowden said. “It’s capturing more of a disposition than a state-like quality.”
Data from the third yearly survey have already come in and await analysis. In addition, researchers are gathering data for the fourth wave, Cowden said. Five annual surveys are planned.
Cowden said the results so far are multilayered and complex.
High levels of forgiveness appear to be a national or cultural attribute of some nations, like South Africa. Other countries, like Japan and Turkey, displayed lower levels.
While the research generally indicated an association between higher forgiveness and greater well-being a year later, the strength of the association varied country to country and in some cases was counterintuitive, requiring a closer look at local circumstances.
For example, South Africa, Cowden said, had high national forgiveness but somewhat weaker associations with well-being about a year later. With high rates of poverty and crime, that could be a case of local circumstances overriding a broader trend.
Similarly, nations with high rates of forgiveness may also have cultures that encourage the behavior, so its benefits potentially could be tamped down because it is widely expected.
“You find more consistent evidence of associations in some countries across the outcomes than others,” Cowden said. “Part of the beauty of the study is that it is trying to consider culture and context.”
Cowden said the overall association, drawn from the results of different nations for 56 well-being variables, was not strong but not trivial either, particularly when considering its impacts at a population level.
The study seeks a deeper understanding of something that cultures and religious traditions have valued as a moral virtue for thousands of years, Cowden said.
Though forgiveness is commonly practiced, we don’t fully understand either its personal impacts or its global contours, he said.
“We’re social beings, and we don’t exist well without social relationships, and if relationships are part of what it means to be human, we’re inevitably going to experience hurts along the way because nobody is perfect.”
Cowden described forgiveness as a “muscle we can build” through practice, and that would be relatively simple to deploy as an intervention under appropriate conditions.
He cited a study published in 2024 that tested the effectiveness of a self-directed forgiveness workbook, based on the widely studied REACH forgiveness model. The three-hour resource was given to people in South Africa, Hong Kong, Colombia, Indonesia, and Ukraine. Respondents reported improved forgiveness, anxiety, depression, and overall well-being.
“If everybody who had unresolved hurts were to experience more forgiveness, the population-level benefits to health and well-being could be quite substantial,” Cowden said.
William Paul, 94Memorial Minute — Faculty of Arts and Sciences
At a meeting of the Faculty of Arts and Sciences on April 7, 2026, the following tribute to the life and service of the late William Paul was spread upon the permanent records of the Faculty.
Born: March 31, 1926 Died: May 11, 2020
William Paul, Mallinckrodt Professor of Applied Physics and Professor of Physics, Emeritus, spent almost his entire career at Harvard, where he was one of the pioneers of experimental solid state physics, with many contributions in the areas of high pressure and semiconductor physics.
Paul was born on March 31, 1926, in Deskford, Scotland. He attended the University of Aberdeen, where he obtained an M.A. in Mathematics and Natural Philosophy in 1946 and a Ph.D. in 1951. The next year, he came to Harvard on a Carnegie Fellowship, attracted by the high-pressure laboratory of Nobelist P. W. Bridgman, where he wanted to test his ideas regarding the effect of volume changes on the electronic structure and optical properties of crystals. His success led to steady appointments as Lecturer, Assistant Professor, and Associate Professor of Solid State Physics in what was then the Division of Engineering and Applied Physics (DEAP). In 1963, he was appointed Gordon McKay Professor of Applied Physics, this at a time when promotions to tenure within the ranks were rare. Between 1991 and his retirement in 2000, he was Mallinckrodt Professor of Applied Physics, with a joint appointment as Professor of Physics.
Paul was a resourceful experimentalist, who brought key innovations to the high pressure field. He developed, for example, strong, flexible steel tubing to bring pressurized fluid into a cell, which made it possible to place the cell in a confined space, such as a low-temperature dewar for measurements. His 1963 book, “Solids Under Pressure,” is widely known in the field. The synthesis of his work on the pressure dependence of the energy gap between electronic states in semiconductors became known as “Paul’s Law,” which states that, for different semiconductors, that dependence is the same at the same points in the Brillouin zone.
In the early 1970s, Paul’s research interest turned to the amorphous semiconductors silicon and germanium, which, at the time, showed promise as inexpensive photovoltaic materials because they could be deposited as thin films from the vapor. Initially, there were concerns that these materials could not be doped because the aliovalent dopant atoms were thought to occur in their natural, non-tetrahedral coordination in the random silicon network. Furthermore, it was feared that the dangling bonds in the network would create an unacceptably high density of states in the energy gap. Paul was one of the pioneers who showed how these problems could be overcome: by depositing the silicon in the presence of hydrogen, the dangling bonds could be tied up, and, by supplying sufficient dopants, a usable fraction could be incorporated with the desired tetrahedral coordination.
When solid state physics emerged as a field in the post-war years, the lack of enthusiasm in many physics departments at that time for this new discipline led to the establishment of more welcoming “applied physics” departments at several major U.S. universities, often as part of their engineering schools. At Harvard, its home was the DEAP, led by Dean Harvey Brooks, a prominent theoretician in the field, who brought in Paul as one of the founding experimentalists. Paul advised more than 40 Ph.D. students and helped establish a strong graduate course curriculum in solid state physics. For several years, he directed the Materials Research Laboratory, which organized multidisciplinary research in materials and provided central research equipment, such as electron microscopes.
Paul stood out as a very articulate colleague who was not shy to voice his opinions and who was well respected for his insistence on precision, due process, and fairness. He could be counted on to speak up at the meetings of the Faculty of Arts and Sciences — and to bring solid figures to support his remarks. He spoke on over 30 topics at these meetings, ranging from student discipline to faculty retirement.
Paul, his wife Barbara (Babs), and their children, David and Fiona, lived in Lexington for many years, where Babs, or “Madame Paul,” was a beloved French teacher in the public schools. In retirement, Paul revived his interest in the theater, staging and directing plays at his retirement community in Bedford.
Paul died on May 11, 2020, during the early months of the COVID-19 pandemic, at the age of 94.

Does vinyl sound better?You don’t have to be a purist to say yes. You might just be ‘album oriented.’
A series of random questions answered by Harvard experts.
Robert Wood is the Harry Lewis and Marlyn McGrath Professor of Engineering and Applied Sciences at the Harvard John A. Paulson School of Engineering and Applied Sciences. His courses include “How Music Works: Engineering the Acoustical World.”
From a purely mechanistic perspective, a vinyl record has information encoded in the meanders of each groove in the record. The needle physically interacts with those grooves, and the resulting needle motion is converted to a proportional electrical signal. It is therefore possible to generate a signal path — from the mechanical grooves to an electrical signal that is then amplified and used to drive a speaker that is entirely analog.
When we convert an analog signal to a digital representation, we take a continuous signal and chop it up into small “slices” that are compatible with storage in a CD, computer, etc. When we play this now-digital audio file back, we reconstruct the original signal, but since we are starting from a digital version the signal is not as smooth as the original; there are subtle discontinuities that could add unwanted artifacts into the audio. If these are prominent enough, and if there is insufficient correction (i.e., smoothing), these jumps could sound choppy and could add subtle but harsh high-frequency noise.
That is the primary argument supporting the audiophile’s claim that vinyl is better. And there is certainly truth to that. But that “purity” is debatable for several reasons.
First, modern digital audio systems are extremely good at reproducing audio signals that are imperceptible from their analog counterparts to all but the sharpest ears. As I describe in my class, even CD-quality audio nearly covers the dynamic range and bandwidth of human hearing. And there are higher-fidelity audio formats — e.g., “super-audio CDs” — that can, theoretically, exceed our human ability to tell analog from digital.
Also, with digital music I can create arbitrary playlists and even mashups of multiple songs. There is nearly infinite freedom with digital music, including suggestion systems that help expand our musical palette and discover new artists and genres. Vinyl records are far less portable and flexible. Cassettes were a successful attempt to achieve portability and some flexibility but could not match the audio quality of vinyl or CDs.
All of this is, of course, highly subjective. The convenience of digital music is hard to beat, but there is something to be said for the warmth and feel and even the pops and cracks from dirt and debris on the surface of a record. And there are other, more subtle benefits to listening to music on vinyl. The most important, to me, is the fact that once I put on a record, I am locked into that record. That is, it is far less convenient to skip tracks than it is with CDs or other digital formats, so I am forced to listen to the album as an album instead of a collection of songs I can shuffle. As a fan of album-oriented music, this is very important to me and arguably something that has diminished in the digital music age.

Known unknownsThe questions that keep scientists up at night
Decades of research have brought us cures for once-untreatable diseases and insights about the farthest reaches of the galaxy. But from evolutionary biology to physics, mathematics to genomics, major unanswered questions keep even the most advanced researchers up at night. We asked some of Harvard’s leading thinkers to tell us what they still don’t know, and what the answers could mean for humanity.
Click on the questions below to learn more.
There are a lot of good ideas floating around about the conditions necessary for life to develop, said Peter Girguis, professor of organismic and evolutionary biology in the Faculty of Arts and Sciences and co-director of the Harvard Microbial Sciences Initiative.
What’s not known — and perhaps not provable — is whether life began on Earth, or if it arrived here from somewhere else. It’s an idea known as panspermia.
It’s a “far out” hypothesis Girguis acknowledged, and one that makes a lot of scientists uncomfortable. It’s theoretically possible that some proto-microbe or bacterial spore hitched a ride to Earth on a meteorite billions of years ago. But science requires reproducibility, and with a data point of one, it’s difficult to prove either way.
“We’re running into the very edges of our ability to use science to address some of these questions,” he said.
Without a time machine, it’s unlikely we’ll prove panspermia one way or the other. But the broader question — whether life exists beyond Earth — is perhaps easier to tackle. In September, NASA reported that a Mars rover discovered chemical compounds that could be evidence of microbial life from billions of years before. It’s the closest sign to date of life on other worlds, but it’s far from a smoking gun.
“I can’t assert that life exists on another planet because I have no data to support that,” Girguis said. “But as a curious and open-minded person, I would strongly argue that I have no scientific data to refute that, either. So if we’re talking about life elsewhere in the solar system or in the universe, I personally lean towards, ‘Yeah, maybe.’”
Also interested in the question of life’s origin is David Kring, the 2025-2026 Edward, Frances, and Shirley B. Daniels Fellow at the Harvard Radcliffe Institute and a principal scientist at the Lunar and Planetary Institute of the Universities Space Research Association.
Kring is a principal author of the impact origin of life hypothesis, which suggests that heavy asteroid bombardment about 4 billion years ago created hydrothermal environments rich in the kinds of chemicals that could lead to life. His team found the remnants of a microbial ecosystem in a hydrothermal system beneath the floor of the Chicxulub impact crater in Mexico.
But, he said, it’s one of several reasonable hypotheses.
“I don’t champion the idea. That’s a notion in science that I find offensive: It means you no longer have an open mind. I just want to know what the right answer is; whatever nature did is going to be interesting.”
Between about 4.4 and 3.8 billion years ago, Earth and other inner solar system planets experienced a period of bombardment heavy enough, in some cases, to vaporize entire oceans. The impacts would have churned the Earth’s crust and created subsurface hydrothermal systems and chemical environments conducive to early life.
Unfortunately, Kring explained, “That period in Earth history is largely erased from the geologic record on our planet.” But there may be another way to get some answers: The same asteroids that bombarded Earth also did a number on the moon.
“By collecting samples of impact craters or impact basins on the moon, we can determine their age and the types of asteroids or comets hitting the Earth-moon system,” Kring said. “Because those impacts jettisoned pieces of early Earth toward the moon, we also have an opportunity, if our minds are open to it, to find bits and pieces of early Earth history there.” Kring has his eye on NASA’s 2028 Artemis IV mission, which is expected to send a crew to the surface of the moon for the first time in more than 50 years.
The incidence of colorectal cancer among people under 50 has been rising by about 2 percent per year since the 1990s, and it is now the leading cause of cancer-related death among that age group.
“The risk factors you may have heard of — obesity, sedentary behavior, ultra-processed foods — are associated with a higher risk of developing colorectal cancer under the age of 50. But I’m not sure those factors fully account for the rise,” said Ng, Harvard Medical School professor of medicine and director of the Young-Onset Colorectal Cancer Center at the Dana-Farber Cancer Institute.
“Obesity has been by far the leading hypothesis, but I and most of my colleagues will tell you that most of our patients are not obese,” she went on. “In fact, many are triathletes and marathon runners. They eat organic. There are no lifestyle factors that could explain why they ended up diagnosed with, unfortunately, Stage 4 colorectal cancer.”
Ng suspects the answer may lie in some combination of environmental and other factors that change the microbiome and the immune system, which surveil against cancer, in ways researchers still don’t understand.
Her team is also studying whether the tumors they see in younger people are different from those in older adults.
“Young people get more treatment and more surgery; they tolerate treatment better and they’re healthier to begin with. But their survival is not necessarily better than that of somebody in their 70s. Why is that? Answering that question could lead to targeted treatment options specifically for younger patients.”
Finding the answers, she said, will require the collaboration of cancer centers and scientists around the world in a variety of disciplines. “We just don’t have any other choice if we want to accelerate the pace of discovery.”
For Thomas Fel, the field of artificial intelligence is full of unanswered questions: How have we built something we don’t understand? What, or how, does AI think? How do we make sure AI doesn’t destroy us? And can we control something we don’t understand?
Fel, a former research fellow at the Kempner Institute and current research affiliate in the Department of Psychology, says the field is still articulating the right way to ask the questions, let alone answer them.
“This is not like understanding a clock or any other system that was built by humans,” Fel said. “This is kind of like reverse-engineering a brain that we accidentally built.”
As AI bots get better at inferring context, building websites, and even chatting among themselves on their own social networks, it gets harder to think of them only as token-predicting machines. However, Fel said, referencing the infamous Chinese Room Argument, “Syntactic manipulation doesn’t entail semantic understanding.” Or, in other words, bots could act conscious, seem conscious, and tell us they’re conscious, all without actually being conscious.
“Right now, we don’t have a theory of consciousness that can definitely say what is and isn’t consciousness,” Fel said. “So the crazy thing is, we might be building conscious machines and not even know it.”
Of course, Fel added, AI doesn’t need to be conscious to be dangerous.
“If it really is, as we think, a really smart system able to distribute itself efficiently, then we can easily imagine having some kind of a bad, bad experience. And the worst thing is, it wouldn’t even be intentional.”
In the AI industry, the subfield of AI focused on making sure the technology acts in humanity’s best interest is known as alignment. To some, the question of AI consciousness is separate from the question of alignment. But Fel doesn’t think that’s right. “Meaningful alignment,” he said, “is fundamentally precarious without a comprehensive understanding of the agency we are attempting to direct.”
Melanie Wood thinks of prime numbers as the fundamental building blocks of integers: They’re to math what elements are to chemists.
“Water is two hydrogen atoms and an oxygen; to me, that’s just like 12 is two times two times three,” she said.
But where chemists have more or less filled out the periodic table of elements (though whether or not heavier elements can be synthesized is another unanswered question), the list of prime numbers is infinite. It’s also random: The distribution of prime numbers among all natural numbers doesn’t follow any regular pattern.
“We can tell you how many primes there are in the first 100 numbers, and then the first million numbers, and up and up, until it’s too big to compute on a computer,” said Wood, the William Caspar Graustein Professor of Mathematics at FAS. But identifying a rule that’s always true remains one of the great unsolved problems in math — in fact, this problem, dubbed the Riemann hypothesis, is one of the six as-yet-unsolved Millennium Prize Problems, with $1 million on the line for the mathematician who cracks it.
“We have all the evidence in the world for the Riemann hypothesis, but we don’t know how to prove it,” Wood said. “We just don’t have any good idea how to proceed.”
Menopause — the end of women’s menstrual cycle and fertility — comes on like a domino effect. Spurred by the gradual loss of function of the ovarian follicles, the menstrual cycle becomes irregular, and the level of estrogen, which is made in the ovaries, fluctuates and progressively declines. Body composition changes, accompanied by changes in cholesterol and blood sugar levels, brain fog, and memory lapses.
For decades, researchers have been exploring whether raising the level of estrogen and related hormones with hormone therapy can slow those physiological changes — and the chronic conditions that can follow.
“Two-thirds of Alzheimer’s disease patients are women, and heart disease is the leading killer of women, especially after menopause” said JoAnn Manson, chief of preventive medicine and the Harvard Medical School Michael and Lee Bell Professor of Women’s Health at Brigham and Women’s Hospital. “So it’s a very natural question to ask: Can estrogen be used to delay the biological aging that occurs? Can it, essentially, preserve health and delay chronic disease?”
Since 1993, Manson has been one of the leading researchers with the Women’s Health Initiative, a landmark study that, among other things, investigated the benefits and risks of hormone therapy in the prevention of chronic disease. But it studied the most common formulation of hormone therapy at the time, oral conjugated estrogens with and without a progestin, not the contemporary “bioidentical” formulation delivered transdermally.
Hormone therapy has been used since the 1940s to help manage menopause symptoms, Manson explained. However, a medical trend started in the 1980s to prescribe hormone treatment to prevent heart disease, stroke, and cognitive decline — all without clinical trials to show whether it was a good idea.
“We really needed the Women’s Health Initiative randomized trials, and they did provide important answers,” Manson said.
The WHI found that younger women closer to the onset of menopause tended to benefit more from hormone therapy than women who were distant from menopause, and that the therapy might be protective against heart disease in younger women. But surprisingly, the WHI also found that there could be serious consequences from the oral hormone therapies available at the time, especially when started later in menopause.
The oral hormone therapy formulations used in the WHI are infrequently prescribed now.
“Contemporary formulations of hormone therapy have never been tested in large-scale randomized trials to understand their effects on clinical outcomes,” Manson said. “That means we need the next-generation large trial to answer the big question — what is the role of hormone therapy in healthy aging? — but this time with the formulations matched more closely to women’s natural hormones and started earlier. This will provide key information relevant to women now and for many generations to come.”
Manson and her colleagues are planning a new large-scale clinical trial to help find the answer.
For the last 780,000 years, the Earth’s magnetic north pole has hovered somewhere around the Arctic Ocean. But episodically, due in part to the chaotic movements of molten metals in the Earth’s liquid outer core, the magnetic polarity reverses.
Paleomagnetic records show that the Earth’s polarity has reversed hundreds of times in the planet’s history. Sometimes, reversals last tens of millions of years; sometimes, only tens of thousands. Planetary scientists don’t have a great handle on why the timelines vary so greatly.
“You can construct computer simulations of the Earth’s core that produce outwardly similar behavior,” explained Roger Fu, professor of Earth and planetary sciences in the Faculty of Arts and Sciences. “But the best supercomputers would still take many decades to really get close to a truly realistic answer.
“We don’t know exactly what would happen if the field reversed, because this hasn’t happened since we’ve been tracking it,” he continued. But models suggest power lines might burn out, satellites would go down, and animals that rely on Earth’s magnetic field for navigation might become confused.
Luckily, reversals take tens of thousands of years, so we should have plenty of time to adjust. “This is mainly a curiosity-driven question,” Fu said. “But people go back and forth on whether the magnetic field is or is not important for life, and this question gets at that.”
To predict how technological advances will impact the labor market, Lawrence Katz has always seen economic theory as a better guide than the fantastic or dystopian visions of science fiction. But when it comes to artificial intelligence, he’s not so sure.
“One view is that economic theory and our historical experience is the way to understand AI. But maybe science fiction writers — and philosophers — who have thought a lot about what it means to be human may be very insightful going forward.”
Katz, the Elisabeth Allison Professor of Economics in the Faculty of Arts and Sciences, is closely watching the impact of AI on jobs, which as of now, he says, is unknowable.
“We’re still in the early stages of seeing what artificial intelligence can do,” he said, “although it’s moving very rapidly.”
Some employers, including Amazon, Meta, and the payments firm Block, have blamed recent or planned layoffs on productivity gains attributed to AI. One Goldman Sachs analysis found AI could automate tasks that make up 25 percent of all work hours.
But the link between the automation of certain tasks and the layoff of a given employee is far from clear, Katz said.
“Most jobs are not one task. So a lot of the open questions are: How does a job get rebundled or recharacterized when some of it gets automated?”
Katz is most worried about entry-level jobs, where young workers got paid to do “grunt work” while learning the tacit knowledge necessary to advance in their fields. Indeed, labor market conditions have worsened for recent college grads, with unemployment ticking up from 5.3 percent in the third quarter of 2025 to 5.7 percent in the fourth quarter.
“New pathways to work, possibly with internships or cooperative education more integrated with traditional college courses, may be necessary to help get workers started on more fruitful career pathways,” he said.
One of the longstanding questions in quantum physics is what’s called the measurement problem: why different rules of physics apply depending on the presence or the absence of an observer. The classic thought experiment is “Schrödinger’s cat,” a creature somehow both alive and dead until somebody opens the box to check.
“Do observers have some kind of magical power to change the rule, so the cat snaps into being either alive or dead but not some blend of alive and dead?” asked Jacob Barandes, a senior preceptor in physics and associated faculty in philosophy at FAS.
Experiments have shown that the act of observation can change the thing being observed; even the order in which one observes certain properties can change the object’s other properties. Other experiments have shown that in some cases, the behavior of two particles can exhibit strange statistical correlations despite the particles being very far apart.
It’s a frustrating conundrum for those of us who live in the world of Newtonian physics, where the rules of gravity and mass are doggedly consistent.
The first proposed solution was the Copenhagen interpretation, Barandes said. That theory proposed a cutoff: Very small things made out of just a few atoms or subatomic particles might behave according to quantum rules, while anything larger behaved according to the rules of classical physics.
But, he added, “Most physicists don’t think there is a line; it would lead to all sorts of questions, like, what if it’s one atom too few? It does seem a little arbitrary.”
A later theory, decoherence, gets a lot closer, Barandes said. Decoherence argues that quantum systems lose their quantum behaviors due to interactions with other molecules and systems. Some in the field consider the measurement problem solved. Barandes doesn’t buy it: “Decoherence doesn’t explain how we get one outcome over the others,” he said.
“I don’t know if this is a problem that’s solvable; I don’t know if it can be solved by an experiment. I don’t know whether solving it would require changing how we think about quantum theory in some more profound way.”
But, he added, the solution may just as well be sociological as physical.
“A variety of questions at the foundation of quantum physics were branded as unscientific, uninteresting, and unworthy of attention by many people in the scientific community, to the extent that working on them in a serious way was actively harmful to a person’s career,” Barandes said. “Much of the work on these problems came from people working on them on the side or in secret, with basically no money.”
That work has already led to major advancements in the field, and to practical applications like quantum cryptography and computing. Just imagine, Barandes said, what would be possible with more investment in the field.
Are your bathroom habits normal?In new book, doctor addresses everything you wanted to know but were afraid to ask
In new book, doctor addresses everything you wanted to know but were afraid to ask
Alvin Powell
Harvard Staff Writer
8 min read
When you’re an expert on the gut, you’re used to conversations others might shy away from. So a book on pooping and what can go wrong in the process is on brand for Trisha Pasricha, a second-generation gastroenterologist whose childhood was marked by matter-of-fact directness.
In her new book, “You’ve Been Pooping All Wrong: How to Make Your Bowel Movements a Joy,” the Harvard Medical School assistant professor of medicine at Beth Israel Deaconess Medical Center shares her sometimes humorous perspective on normal and abnormal bathroom habits. In this edited conversation, Pasricha — who also is the director of research for the Institute for Gut-Brain Research at BIDMC and writes The Washington Post’s “Ask a Doctor” column — discussed emerging knowledge that may illuminate poorly understood conditions like irritable bowel syndrome, the damage a doctor’s doubt can do to patients, and her optimism about her fast-changing field.
In addition to your clinical and research work, you author The Washington Post’s “Ask a Doctor” column. Did that help in writing this book?
Yes, every time we write about gut health it vastly outperforms any other health topic. Even an embarrassing topic like fecal incontinence or farting would do well. That tension is partly why I wrote the book. I think people want good, accurate information and want it without having to make eye contact with their doctor. And we want people to engage early, especially in this age of early onset colorectal cancer.
It seems like you went through some effort to find the right words. Is it poop? Is it a bowel movement? How did you settle on your language?
A dash of humor helps when you’re talking about something that makes people feel ashamed and vulnerable. Medical school trained me to say “bowel movement,” then I started shadowing a gastroenterologist who would go on to become a mentor for me. A patient came in — a younger guy, college-age — and my mentor’s opening line was, “So, tell me about your poop.” The patient had been awkward and nervous, but as soon as my mentor said that, the whole atmosphere changed. I thought, “This is what I should be doing.” This person immediately opened up. He was relieved, and he told the doctor exactly what was going on.
With our reluctance to talk about it, do people really know what normal is?
I don’t think so. When I was starting out on my own, people would tell me about their specific problem, but if you gave them the chance to step back, what they were really curious about was the basics. How many times a day is normal? What colors are normal? How mushy or soft or hard is stool supposed to be? I worry that when people don’t know what normal is, especially what normal for them is, how will they know when something is abnormal?
“I hope it’s validating to people who have ever felt that they haven’t been believed that there’s a whole world of scientists and doctors who are working on this problem.”
You point out that there’s wide variety within the “normal” range. What should people look out for?
It’s not just once a day or bust. The range of normal is going between once every three days and three times a day. You can live a full, healthy life anywhere in that range and be fine. What’s important is when there’s a change. If you are somebody who generally goes two or three times a day and now you’re going every other day, even though that is somebody else’s normal pattern, this is a change for you. And colors are important. It’s not always a healthy shade of brown. When you see red, when you see maroon, when you see something black, tarry, sticky, it’s important that you don’t just brush it off. Let your doctor know about it the day it happened.
What are specific conditions these changes might be signaling?
There are lots of different diseases that start in the gut. And there are a lot of gut conditions that may or may not get a diagnosis or a name but are causing you trouble. Most urgent is cancer, but there are other things that cause bleeding and pain, like inflammatory bowel disease. Diverticuli can bleed, hemorrhoids can bleed. There are also things that probably won’t kill you but are difficult to live with. There’s irritable bowel syndrome and other causes of constipation and chronic diarrhea. And there are people who have GI issues, but no diagnosis: Three out of four people can’t poop in public and one in three can’t go to the bathroom on vacation.
Is this a field that’s advancing rapidly?
Definitely. Neurogastroenterology is the most exciting field in GI, though I’m obviously biased. For the longest time we weren’t getting deep enough into the enteric nervous system, into those deep muscle layers of the gastrointestinal tract. So, for about a century, what we were studying was how the brain influenced the gut and what we could observe with our naked eye about its effects on the gut. But now that we’re more and more able to look at those neurons and cellular changes, the whole field is exploding. Every few years there’s a profound breakthrough that upends everything we’ve learned.
Is the new understanding of the gut-brain connection both cutting-edge and misunderstood, even within the medical profession?
That’s exactly right. One of the most common diseases of our specialty, irritable bowel syndrome, is probably one of the most common disorders in all of medicine. It affects 15 percent of the population and yet is poorly understood by the public and by a lot of doctors because these advances are new enough to have happened after many of them got out of medical school. We haven’t done a fantastic job disseminating that knowledge to people outside neuro GI. That was one of the other reasons I wanted to write this book, to make sure people knew everything that I knew about irritable bowel syndrome and how the gut’s communicating with the brain. Because if you don’t know the data, it can sound really fringe.
Some of the stories you tell, particularly about your interactions with your father — you have to trust the patient — seem like important messages for other doctors to hear.
That was a lesson that stuck with me for life. It’s why I decided to end the book on that note. I recognize that we doctors struggle when we don’t know the answers. It’s hard to be a doctor whose patient is suffering. Not only do you not have a treatment for their suffering, but you don’t even understand where the pain is coming from. So I hope the book shifts our thinking when tests come back normal in a patient with IBS. Instead of simply saying, “You need antidepressants,” we change the way we talk to them. We accept that they have abnormalities even though they’re not being captured by the test. That’s when the conversation changes and trust between doctor and patient is transformed. It’s powerful and may point you toward making the right referral or thinking outside the box for medications that you wouldn’t have thought of before.
Is not believing patients a big problem in medicine? It’s cited by IBS sufferers quite a bit and I’ve heard the same thing about long COVID.
I think about this all the time. It’s not just irritable bowel syndrome, although irritable bowel syndrome is a big part of long COVID. It’s other conditions like migraines. All the brain scans and blood tests are negative and yet they’re living with this difficult condition. They feel dismissed. We are taught in medicine to think algorithmically: Here are the set of abnormalities, here’s the pattern, put that puzzle together. When you feel like there are no pieces to put together because there’s no clue you can latch onto, it’s easier to say this is in the patient’s head rather than it’s something that we might not be capturing yet. But we will start to capture those things in tests in the next 15 years and suddenly we’re going to stop telling people “This is all in your head” simply because we’ll see it.
What are the main takeaways for readers of this book?
I hope people walk away from it feeling reassured, feeling like, “You know what? I’m not weird or abnormal. There are a lot of people dealing with exactly the same thing I’m dealing with.” I hope, too, that they feel reassured by the practical tips I give for the day-to-day problems that more people suffer from than we might know because we don’t ask about it, don’t talk about it. I also hope it’s validating to people who have ever felt dismissed or felt that they haven’t been believed, that there’s a whole world of scientists and doctors who are working on this problem.
Time has not been kind to VHSAs tech turns 50, preservationists race to save material stored on vanishing format. Methods include … baking?
As tech turns 50, preservationists race to save material stored on vanishing format. Methods include … baking?
Before streaming, before Blu-ray, and before DVDs, the VHS videocassette was the king of video. First launched in Japan in 1976, the format, short for Video Home System, was easy to use, compatible with any television, and affordable.
After winning the battle for dominance with the Betamax cassette, the VHS ushered in an era of amateur filmmaking, home movie collections, and video store rentals. Recognizing the value of the new format, Harvard curators quickly began amassing materials on VHS. Though no single tally of Harvard’s VHS holdings exists, a 2018 count of audiovisual material says the figure is likely in the tens of thousands.
But 50 years after its launch, the technology is all but obsolete. The cassettes’ magnetic tape degrades over time, putting curators, archivists, and conservators in a race against the clock to salvage as much as they can before it’s too late.
In a climate-controlled storage vault, Joanne Donovan recently rifled through stacked cardboard boxes and pulled out a VHS tape titled “Honoring the Wisdom of Experience,” dated Nov. 11, 1995. The tape is part of the papers of Louisa Pinkham Howe, a sociologist and psychotherapist who, among other achievements, testified in Brown v. Board of Education that racial segregation was psychologically damaging to children.
The tape has not yet been digitized.
“Digitization is very much a priority, considering how ephemeral this format is,” said Donovan, lead archivist for visual materials and recorded sound collections at the Harvard Radcliffe Institute’s Schlesinger Library. “There’s not as much information available about the history of women, and women of color in particular. There’s a risk of it being lost.”

Joanne Donovan shows a storage area where VHS tapes are kept at Schlesinger Library.
The Schlesinger, which collects materials related to the lives of American women, holds about 5,000 VHS tapes. According to Donovan, only about a quarter of the collection is available digitally.
Lately, when videos come back from being digitized, they’re often “snowy,” a sign that the tape was too degraded for a clear capture.
The VHS era — the mid-1970s through the late ’90s — saw a huge transformation in culture, Donovan explained, and much of it was documented on VHS’ Mylar tape. The Schlesinger’s VHS holdings include materials from the women’s music movement; oral histories; recordings of luminaries such as chef Julia Child, lawyer Florynce Kennedy, and poet June Jordan; and training videos from Lamaze International and the National Organization of Women.
Elsewhere at Harvard, many items in the Busch-Reisinger Museum’s VHS collection come from Joseph Beuys, a German artist and theorist known for embracing new media.

“Beuys in particular was part of a generation of artists who saw the videocassette as a kind of democratizing medium,” said Lynette Roth, Daimler Curator of the Busch-Reisinger Museum. “It was a way to make art more accessible and less elitist compared with traditional media, like painting, for example.”
But ironically, video art often languished in museum archives.
“You can’t really use the videocassette; you’ll wear it out. So these artworks were underrepresented in our galleries,” Roth said.
To finally make good on Beuys’ egalitarian vision, Susan Costello, the conservator of objects and sculpture for the Harvard Art Museums, is overseeing a project digitizing analog media, including VHS tapes.
“You would think it’s pretty easy: You just box everything up and send them over to be digitized. But it’s actually quite a lot of work,” said Costello. “The curatorial department had to put values on all of them, because they’re works of art. We needed detailed condition reports before they left the building so we knew if anything happened to them. Some of the items needed new casing made for them to make it safe to ship them.”
“You would think it’s pretty easy: You just box everything up and send them over to be digitized. But it’s actually quite a lot of work.”

In May of last year, professional art movers loaded about 70 pieces of analog media into a climate-controlled truck and brought them to Harvard Library’s Media Preservation Lab.
There, head of media preservation Kaylie Ackerman, senior time-based media conservator Melanie Meents, and their teams are racing against the clock to preserve the contents of the fragile plastic cases.
One problem: sticky shed syndrome. Instead of spooling smoothly off the reel, some poorly preserved tape adheres to the layer below it.
“If you just play the tape, you start ripping oxide off it, which erases the tape in the most heinous way possible,” Ackerman explained.
The solution is remarkably low-tech: baking. Using special laboratory ovens that are capable of holding a constant steady temperature, Ackerman bakes VHS tapes at 125 to 130 degrees Fahrenheit for up to five days.
“If you can bake the tape at a particular temperature for a particular amount of time, you can temporarily re-cure the material for long enough to get a good preservation transfer,” she said. It’s a high-stakes gamble: There might only be one chance to read the tape before it’s too degraded to try again.
“The reason we digitize it is that otherwise it would just disappear,” she continued. “These are things that support scholarship, that support research, teaching, and learning throughout the University. It’s important for Harvard to not only have the material, but preserve it, so that in 150 years a new scholar can still work with it as a primary resource.”
Demystifying migraine‘It’s not an imagined headache, and it’s not a mild condition,’ says Michael Moskowitz, Brain Prize recipient for his dogma-defying research
About 15 percent of people worldwide suffer from migraine, a neurological condition that can cause headache, nausea, visual disturbances, and sensitivity to light and sound.
The condition is also undertreated and poorly understood, says Michael A. Moskowitz, Harvard Medical School professor of neurology at Mass General. Moskowitz has made multiple discoveries that have revolutionized thinking about the condition, deepened knowledge about why some treatments work, and led to new treatments that are available and prescribed now.
Moskowitz’s interest in neurology began early. At 14, he worked as a messenger in a hospital for patients with chronic neurological diseases near his family’s home in New York City, and was shocked by what he saw. “I could not comprehend how the brain could so easily betray the body,” he said.
When he began his career in the early 1970s, migraine was still poorly understood. Images of the brains of patients came back totally normal: On paper, there was nothing wrong.
“When I first started in the field, many people believed that migraine was a psychological problem,” said Moskowitz. “But it’s not an imagined headache, and it’s not a mild condition.”
His first step, when he was a postdoctoral fellow and junior faculty in the Harvard-MIT Program in Health Sciences and Technology, an inter-institutional collaboration between Harvard University, Harvard Medical School, and MIT, was to dive into the literature.
“I don’t know how many nickels I dropped in the Xerox machine at the Countway Library, but quite a few,” he said.
“When I first started in the field, many people believed that migraine was a psychological problem.”
He found that no scientist had yet mapped the nerves carrying sensation from the circle of Willis, a network of arteries in the innermost layer of the meninges that supply blood to the brain. The brain itself doesn’t register pain, but the meninges, the brain’s three-layered covering, do. It seemed a promising place to start.
So using a novel polymer-based technology developed in partnership with MIT chemical engineer Robert Langer, Moskowitz showed that nerve fibers that wrap around the circle of Willis travel back to the brain via the trigeminal nerve, which also carries sensation from the forehead, where headaches are often felt. His lab then found that these nerves contain and release neuropeptides, setting up a cascade that causes meningeal inflammation and other harmful effects.
It was a stark departure from the previous belief about migraine, which was that the condition was purely caused by the dilation of blood vessels.
In later research, Moskowitz demonstrated that classical migraine drugs called ergots and triptans acted in a completely different and unexpected way than had been assumed: Rather than constricting blood vessels, the drugs blocked those harmful neuropeptides from being released from nerve fibers in the first place.
“That changed 100 years of dogma about how the ergots worked,” Moskowitz said. It also led to a new class of drugs that blocked neuropeptide release without vessel constriction In addition, it led to the development of drugs and antibodies that block the action of CGRP, a major neuropeptide in this pathway; those drugs are still in use today. Other neuropeptides discovered through his research are providing promising leads for future migraine therapies, said Moskowitz, who in 2021 received the Brain Prize for his contributions to migraine research.
Building on the breakthrough, his lab began to look for the trigger that caused the release of peptides in the first place. They identified cortical spreading depression, a slow-moving tsunami of electrical and chemical changes in the brain. As the wave progresses, it can trigger migraine’s varied symptoms. For example, the migraine’s classic visual aura occurs as the chemical and electrical changes move through the brain’s visual cortex.
Moskowitz’s research is also focused on the study of stroke and its potential neurovascular targets. In 2024, he and his chief collaborator, Matthias Nahrendorf, an HMS professor of radiology at Mass General, were awarded a Javits Award, a prestigious seven-year research grant, from the National Institutes of Health. Along with another collaborator, Charles Lin, an HMS professor of dermatology at Mass General, they are following up on new discoveries showing that the skull bone marrow and its blood-forming inflammatory cells contribute to the health of the meninges. The findings could impact a variety of neurological diseases, including stroke, Alzheimer’s disease, and multiple sclerosis.
“My research has been 98 percent funded by the NIH over the course of my career,” Moskowitz said, expressing gratitude for the federal partnership that allowed bench-to-bedside medicine to flourish. “I can say with great confidence that if it weren’t for the NIH, we definitely wouldn’t have these new migraine drugs that block headaches.”
Is a more perfect union still possible?Faust, Buttigieg, and Glaude look at past, present of nation’s divides

Faust, Buttigieg, and Glaude look at past, present of nation’s divides
During a talk Monday evening at Harvard Kennedy School, a panel of American history scholars and political analysts discussed the forces of the present and the past animating the country’s divisive political climate and whether there remains a path to a more perfect union.
Drew Faust, a Civil War historian and president emerita of Harvard, and Eddie S. Glaude Jr., a scholar of African American studies and religion at Princeton, said in many respects the schism in today’s U.S., which often feels like a loosening confederation of Red and Blue states, can be traced back to the North/South divide over slavery during the Civil War.
In fact, social scientists and economists have noted the persistence of political and economic differences that remain between former Union and Confederate states.
While there is much ideological and sociological overlap, Glaude cautioned against leaning too heavily on that geographic dichotomy to fully explain the current partisan rift because it “overburden[s] the South” and “feeds the myth that the moral problem resides there, as opposed to in the heart of the nation.”
“If we’re going to get to a good place again … it’s going to be because people do something and decide that union matters and that we want to be a nation that is unified.”

The discussion was the first in a new series recognizing the country’s 250th anniversary and the need for “straight talk” during “hard times,” said Jill Lepore, David Woods Kemper Professor of American History at Harvard and a New Yorker staff writer, who is moderating the series.
A second event, on April 13, will feature Mitt Romney, who was formerly a U.S. senator of Utah, governor of Massachusetts, and the Republican nominee for president in 2012.
The nation’s history “doesn’t have to be destiny,” said Pete Buttigieg ’04, who served as U.S. secretary of transportation during the Biden administration and mayor of South Bend, Ind., from 2012–2020. He’s currently a visiting fellow at the Institute of Politics and a Hauser Leader at the Center for Public Leadership.
“We’re actually in one of those rare moments which, for all of the pain and the pathology of being an American right now, could also be an incredibly fertile moment for different patterns, different coalitions, and perhaps a very different electoral map in the near future,” he said.
Whatever comes next, that future has to be truly different, Buttigieg said.
“If there’s one thing I’m preaching right now, it’s that our job as a country and the job of my political party is not to somehow take power, find all the bits and pieces of everything they smashed, remember how it used to look, tape it all back together and serve up the world as it looked in 2022 — because that’s not going to work,” he said.
The panel considered the range of generational, socioeconomic, and educational factors that can improve or worsen divisions and how it’s important to not only think and talk about ways to bridge those gaps, but to take action to make it happen.
“Union doesn’t just come automatically. We’ve had to struggle for union” since the earliest days of the nation’s history, said Faust.
“And so, if we’re going to get to a good place again … it’s going to be because people do something and decide that union matters and that we want to be a nation that is unified,” she said.
Institutions such as universities and the U.S. military still play key roles nurturing union by gathering people from different places, with different values, beliefs, and experiences to live and work together toward a common purpose, Faust and Buttigieg said.
The group was asked whether they thought it was still possible to salvage the term “union” given the divisiveness of our politics and social media’s power to fuel it.
Glaude said that it can be done, but it will require deep reflection about the obligations we have to each other as Americans and what it will take to renew a commitment to working together toward a greater common good.
“What we’ve witnessed over the last 50-plus years is an evisceration of any robust notion of the public good. We’ve become self-interested persons in pursuit of our own aims and ends, in competition and rivalry with each other,” he said.
“What does it mean for us to imagine ourselves differently? That’s not going to come from politicians. It’s not going to come from prophets who were anointed from on high. It is going to come from us, understanding our role.”

In her latest book, “Frog and Other Essays,” Anne Fadiman ’75 writes about topics ranging from a dead pet frog to her attachment to an old printer. The literary essayist, journalist, and editor, who is also a professor and writer in residence at Yale, recently spoke to the Gazette about themes in her new collection, a summer stint at Harvard Magazine that helped her hone her craft, how students can become better writers in a month, and AI’s impact on education and literature. The following interview has been edited for clarity and length.
Your parents were both writers. Could you talk about your family’s influence on your love for books and words?
My parents had about 7,000 books between them, but they rarely pressed books on us. They simply told us that we had free range. So, my brother and I were always taking down books that were over our heads and trying them out. My father later wrote about how much he hated children’s books that had short words and talked down to their readers. He said the only way to enlarge a rubber band is to stretch it, and he believed the same goes for children — that they should always be reading things that are a little too hard. As for words, I’ve always loved them. Other families play games with balls; the Fadimans played games with words.
How did Harvard help you become a writer?
Harvard had no creative nonfiction classes when I was there in the early ’70s. I took a couple of fiction classes, and the main thing they taught me was that I shouldn’t be a fiction writer. But I had two mentors at Harvard Magazine (called the Harvard Alumni Bulletin until 1973): editor John Bethell, who is now in his 90s and to whom I’m still very close, and managing editor Kit Reed, who died in 2017. I did an independent study with them. If it hadn’t been for those two, particularly John Bethell, who’s the best editor and best writing teacher I’ve ever had, I doubt my career would have unfolded in the same way.
When I worked at Harvard Magazine the summer after my junior year, John had me write for every department, including sports and obituaries. During the day I’d write what I thought was a work of genius, and then, after hours, John and I would sit together and go over it line by line. And I would realize, “Oh, well, it’s possible that this is not a work of genius.” But it can get better. Today I use that same form of teaching with my own students, sitting with them and going over their work line by line. John’s teaching made me a better writer on the sentence level. That’s something most young journalists never get from their editors.
Early in your career, you wrote reported magazine articles, and now you write mostly essays. What drew you to essays?
Until I was middle-aged, everything that I published was reportorial nonfiction, and everything since then has been essays or memoir, which isn’t to say that I won’t ever return to reportorial nonfiction. I had never published an essay in my life until age 41, when I was stuck in bed during a problem pregnancy and couldn’t do any reporting. I discovered that the essay was a form to which I was well suited — one I love to read, and one I still love to write.
Essays were more or less invented in the 16th century by Michel de Montaigne, who was also the mayor of Bordeaux. He called them “essays,” from the French “essayer” — to try, to attempt. They were about very personal subjects like kidney stones, drunkenness, and fear. Nobody had read anything like them before. In my case, I had never thought I was sufficiently interesting to write about, but I found that the essay form, particularly a subset of the personal essay called the familiar essay, is ideal for me because I love research. The familiar essay is framed by the author’s experience, but it’s also about a topic.
Your latest book includes essays about a dead pet frog, your struggles with Zoom, an old printer, and the periodical The South Polar Times, among others. What do you hope readers take away from these essays?
After I read from “Frog and Other Essays” at a bookstore recently, an audience member asked why I wrote about apparently trivial topics when there were so many difficult things happening in the world. Here is one answer. The South Polar Times was a magazine that circulated among the men on two early Antarctic expeditions led by the British explorer Robert Falcon Scott at the very beginning of the 20th century. These men were facing terrible risks, and Scott decided a periodical published during the months without sunlight might prevent them from getting cabin fever and remind them of the aspects of the world and their lives back home that were funny or beautiful or tender. It was hand-typed by one of the explorers once a month and circulated like a sacred text among men of all different ranks. That’s what kept their spirits going; that’s what they needed when they were facing death. We need beauty, wit, and attention to small things even more when we have to face large, painful things.
“I often start an essay in a place as small as possible and then let it open up.”
I often start an essay in a place as small as possible and then let it open up. My essay about my stubborn refusal to get rid of my obsolete old printer eventually leads into a discussion of growing old and how people my age are worried about becoming obsolete ourselves. I hope readers will take from these essays the notion that large things can come from small things, and that they should never feel their own lives are trivial.
You’ve been teaching nonfiction writing at Yale for 21 years. What advice can you offer to aspiring writers?
Ask yourself, “What am I trying to say?” and make sure that everything in the piece you’re writing answers that question. Then cut out everything that doesn’t.
If you want to become a better writer in a month, I suggest you spend that time not writing but reading the complete works of E.B. White. If you read those works all day every day, that would take you about two weeks, and then you could read them all over again. Simply by osmosis, the beauty and clarity of White’s sentence structure would penetrate your brain. I feel sure you’d be a better writer at the end of the experiment.
Finally, are you concerned that AI might pose a threat to writers?
I think AI is a terrible threat, not only to creativity but to ethics. It turns honest students into cheaters simply because they see everybody else cheating, and because it makes cheating so easy. It’s a well-greased slide. You ask ChatGPT to suggest a synonym for a word or phrase, using it in a perfectly honest way as an online thesaurus. But then it will say, “May I draft a sentence for you? May I draft a paragraph? Why don’t you tell me your main points so that I can draft the whole essay?” And down the slope you go. AI is going to change both education and literature. I think it’s going to be like B.C. and A.D. B.C. is about to end: the period during which all books were actually written by humans.
I can’t say that AI has affected my own writing classes at Yale. Like most of my colleagues, I get to choose my students from a large pool of applicants. They’re the students whose voices interest me, but they’re also the ones who are most motivated to learn how to write better. They don’t want to do less work; they want to do extra work. So far, I haven’t been able to sniff out even one AI-written sentence. The day that starts to happen will be the day I quit my job and the day my heart gets broken.
Powell issues a warning on U.S. debtCurrent trends ‘not sustainable,’ says Fed chair, whose conversation with Harvard undergrads also touched on inflation, impact of war, independent decision-making
Current trends ‘not sustainable,’ says Fed chair, whose conversation with Harvard undergrads also touched on inflation, impact of war, independent decision-making
Federal Reserve Chairman Jerome Powell expressed confidence in the “resilience” of the U.S. financial system during a visit to Harvard on Monday and said that the Fed will take a “wait-and-see” approach to the economic impact of the Iran war.
Powell spoke at Sanders Theatre with undergraduates in “Principles of Economics,” a macroeconomics course co-taught by Jason Furman, Aetna Professor of the Practice of Economic Policy at the Kennedy School and in the Department of Economics, and David Laibson, Robert I. Goldman Professor of Economics. Laibson moderated the talk.
Powell said that the Fed remains committed to its target inflation rate of 2 percent even against headwinds created by U.S.-imposed tariffs and the conflict in Iran. The Federal Open Market Committee thought the goal was within reach in late 2024 when U.S. growth was at 2.5 percent, 12-month inflation was just above 2 percent, and the labor market was essentially at full employment. These data followed a period of serious recession worries among many economists.
“I would call that a soft landing,” Powell said.
Nominated to serve as Fed chair by President Trump in late 2017, Powell was nominated a second time by President Biden in 2021. His term officially ends in May, but he has said that he will remain as chair until his successor has been approved by the Senate.
Historically, the Fed tends not to react when oil and gas prices rise because energy supply shocks are often short-lived, so the central bank will “wait and see” how Iran-related oil prices affect the broader economy and will monitor inflation expectations “very, very carefully” before making any policy adjustments, Powell said.
He expressed deeper concerns about the nation’s balance sheet. Our $39 trillion debt is not the real problem, he said; it’s that the current path Congress is on — spending more than the U.S. is taking in — is “not sustainable.”
“The country has to get back to ensuring that the economy is growing fast enough to keep pace with spending,” he said.
“It will not end well if we don’t do something fairly soon,” Powell warned.
On emerging threats, Powell said that the Fed has taken significant measures to fortify the U.S. financial system against outsized risks and credit losses like those that fueled the 2008 global financial crisis.
“We have a hugely resilient financial system,” he said.
With the financial sector constantly evolving, what the country needs from the Fed is “vigilance,” not the elimination of all risk, Powell said. “You just need to always know that there’s another thing coming.”
The Federal Open Market Committee is monitoring private credit markets “super carefully,” he said, but at the moment sees no systemic threat to the nation’s financial stability.
Asked by a student about the Fed’s view of employment, Powell acknowledged a tough labor market for younger people. But given U.S. dynamism and growth since World War II, he urged students to be optimistic about the medium- and longer-term economic outlook and to become comfortable and proficient with AI.
Though Powell did not comment on Trump’s nominee for Fed chair, Kevin Warsh, he did make a case for the importance of Fed independence and rejected the idea of partisan motives in the central bank’s policymaking.
“We’re not trying to work against any politician or any administration, but we have to be careful to stick to what we’re doing,” he said, adding: “The Fed is not a perfect institution. What we do is very challenging, highly uncertain, but it’s a great American institution and I’m very proud to work with the people I work with.”
Many observers have warned that any effort to interfere with the Fed’s traditional independence from politics would threaten significant harm to the financial system and to the country. “It’s very hard to build great democratic institutions and much easier to bring them down,” Powell said.
The ascent of usAnthropologist traces split between Homo sapiens and Neanderthals, other human forms
Anthropologist traces split between Homo sapiens and Neanderthals, other human forms
The triumph of Homo sapiens over Neanderthals, a huge step in human evolution, was not the clearcut event that paleontologists have long believed.
More likely, it was the result of continued interactions — and even some interbreeding — with modern humans resulting from just one surviving group.
At a Peabody Museum event March 25, Professor Jean-Jacques Hublin drew on cutting-edge research in archaeology, paleogenetics, and paleoproteonomics to examine that transition in Eurasia, tracing the processes that during the Paleolithic period gradually transformed a world of multiple human forms into one inhabited by a single surviving lineage.
Speaking as part of the Hallam L. Movius, Jr. Lecture Series, Hublin, professor at the Collège de France (Paris) and emeritus professor at the Max Planck Society, began by referring to the work of the series namesake, a groundbreaking archaeologist who focused on the Paleolithic.
It was Movius, Hublin said, who first pointed out that the tools — or “industries” — left behind by the different groups hinted at the distribution of these populations.
“If you look at the evolution of paleolithic industries throughout the Old World, you have very different stories depending on what part of the world you are,” he said.
Neanderthals and Homo sapiens were quite distinct species, Hublin explained.
For example, although they were likely only separated 800,000 to a million years ago, the skulls and jawbones of these hominins are more markedly different from each other than those of chimpanzees and bonobos, which separated one and a half million years ago.
The two hominin species also, at least initially, lived in different areas, with Neanderthals primarily living in a moderate climate swath that stretched across Europe into Asia, and Homo sapiens living in Africa, before they migrated north in a series of moves.
They were not the only early hominins.
“More than 40,000 years ago, you had all these different hominins existing,” Hublin said. In Eurasia, for instance, two sister groups, the Neanderthals and the Denisovans, apparently coexisted.
“So we have a divide between an African world where our species evolve and a Eurasian world where the Denisovans and the Neanderthals evolve. And at some point, our species replaced all the others,” said Hublin, calling that event, “the most spectacular event in hominin evolution of the last million years and arguably the most important event of the whole human evolution.”
That event was likely the result of a long history of interactions.
“We know from ancient DNA that there were already contacts probably more than 250,000 or 300,000 years ago,” said Hublin.
The proof, he said, lies in the genome of Neanderthals who came after this period, which contain mitochondrial DNA, a part of the genome of the African people, ancestors of present-day humans. This DNA, he said, is transmitted through maternal lineages, suggesting some interbreeding between species.
This “hybridizing,” or inter-species mating, is now seen as something that happened several times rather than as a one-time occurrence.
Such genetic evidence has countered older theories that postulated that “you have modern humans coming into Europe, moving as a wave, replacing them.” he said. “Reality is more complex.”
Another way to trace these two groups is through their technology. He said hand-held cutting tools, created by chipping away at stone to form sharp edges, are distinctive to their users, and he illustrated the point with a series of slides.
Digs associated with European Neanderthals, for example, are characterized by “shapeless flakes,” according to Hublin. But in areas populated by Homo sapiens, sharpened stones were increasingly focused on a tip, possibly enabling users to put them on the end of a stick or other projectile, making a spear for hunting.
“This prevalence of points and projectiles is something that we see already in Africa before the spread of these hominins into Western Eurasia,” he said.
Some European sites, however, have turned up similarly sophisticated tools. Originally, archaeologists had theorized that Neanderthals had developed these independently, even simultaneously with Homo sapiens. However, newly found Homo sapiens teeth at these sites link the better tools to incursions by our ancestors earlier than had been previously known.
This work was enabled by a new technology developed at the University of York in the United Kingdom. The technology extracts collagen from bone fragments, from which a protein fragment known as a peptide is extracted.
Using a mass spectrometer, which “basically measures the size of this fragment,” said Hublin, researchers can identify differences that are specific to each species.
These findings show that populations of Neanderthals and Homo sapiens coexisted in Europe for thousands of years, perhaps as early as 55,000 to 53,000 years ago, probably separated by topical barriers — mountains, for example.
And while some groups intermingled, given the DNA evidence, other groups likely had more hostile interactions, as indicated by the presence of Homo sapiens bone fragments in the piles of refuse.
The result is a much more complex picture of our origins than had been believed.
“We have exchanges between the two groups at the gate of Africa. We have this integration of mitochondrial DNA microsomes that existed in the past. More recently, we had an integration of Neanderthal DNA into the genome of present-day humans outside of Africa,” he said. “So most people in this room have about 2 percent DNA of Neanderthal origin.”

In podcast, experts discuss factors fueling housing crisis — from overregulation to NIMBYism — and how to fix it
Last year, home prices surged to nearly five times the median income. It’s no wonder that increasing numbers of middle-class Americans feel like the dream of owning their own home is out of reach.
“When you have robust demand to live in a place that then collides against a relatively fixed supply of housing, you are going to end up having high prices,” said Edward Glaeser, an award-winning urban economist and the Fred and Eleanor Glimp Professor of Economics.
Political solutions can be tricky given the competing interests of housing haves and have-nots, says Jason Furman, the Aetna Professor of the Practice of Economic Policy at Harvard Kennedy School and former chair of the Council of Economic Advisers under the Obama administration. Yet some states have responded creatively to the crisis, according to Amy Tomasso, a director of the nonprofit Ivory Innovations and former research fellow at the Joint Center for Housing Studies.
In this episode of “Harvard Thinking,” host Samantha Laine Perfas talks with Glaeser, Furman, and Tomasso about factors driving the housing crisis — and their prescriptions for fixing it.
Edward Glaeser: The people who own their homes? The rise in housing prices isn’t a problem for them. It’s an increase in the price of their most valuable asset, and they’re benefiting from this stuff. But it’s the outsiders who pay the price.
Samantha Laine Perfas: Homeownership has played a central role in the American concept of wealth and stability, but the dream is feeling more and more unattainable for many middle-class Americans. Last year, home prices surged to nearly five times the median income. Yet the pace of new housing builds — which could create more affordability — remains slow. So if existing homes feel out of reach and there aren’t enough new homes being built, what does that mean for the people hoping to buy?
Welcome to “Harvard Thinking,” a podcast where the life of the mind meets everyday life. Today I’m joined by.
Glaeser: I’m Ed Glaeser. I’m the Fred and Eleanor Glimp Professor of Economics in the Department of Economics in the Faculty of Arts and Sciences.
Laine Perfas: He is an award-winning urban economist and has written hundreds of papers on cities and infrastructure. Then:
Amy Tomasso: I am Amy Tomasso. I’m the vice president of policy and partnerships at Ivory Innovations.
Laine Perfas: Ivory Innovations is a University of Utah-based nonprofit that seeks to catalyze innovation in housing affordability. Amy studied at Harvard’s Graduate School of Design and was a research fellow at the Joint Center for Housing Studies. She holds a master’s from Harvard. And finally:
Jason Furman: Jason Furman. I’m the Aetna Professor of the Practice of Economic Policy at Harvard Kennedy School.
Laine Perfas: He’s also a professor in the economics department and served as chair of the Council of Economic Advisers under the Obama administration.
And I’m your host Samantha Laine Perfas, a writer for The Harvard Gazette. Today we’ll talk about homeownership and how the housing market affects the economy, our communities, and people’s pursuit of the American dream.
I’m going to start with a question that could be the only question for this whole episode: Why is it so difficult to buy a home right now, specifically in high-demand areas?
Glaeser: You don’t go wrong starting out with supply and demand, right? When you have robust demand to live in a place that then collides against a relatively fixed supply of housing, you are going to end up having high prices. First, the supply of new houses dried up in places like Boston and New York and coastal California, and increasingly places that used to be superstars of production — like Atlanta, Georgia, Phoenix, Miami — became places in which building has also radically slowed down. An increasingly large swath of America has faced a housing supply that has been straitjacketed. And the upshot is housing costs far more than it should.
Tomasso: A short answer I would give to why it’s so hard to buy a home is that it’s hard to build a home. This isn’t a new story. Housing starts have declined over the last 30 years. While we’re in an acute housing crisis now, it’s been in the works for quite some time and estimates show that we’re around 2 to 4 million homes short of where we need to be in the U.S. There’s this perfect storm of contributing factors: the overlapping regulations; demand has created high home prices; we’re also seeing high interest rates, high insurance premiums, and property taxes. All of this amounts to the lowest levels of home-buying since the mid-’90s.
Furman: I want to pick up on the high interest rates that Amy just mentioned. The fact that the United States is running the largest budget deficit of any of the rich countries in the world — it now has a debt equal to the size of our economy — you may wonder why should that matter for housing? It drives up interest rates. When interest rates go up, it affects both supply and demand. If you’re trying to build houses as a builder, it’s harder for you to borrow money when you’re competing with the federal government. And, of course, it also affects the demand side, which is mortgage rates today are 6 percent. For some people whose memory goes way back, 6 percent sounds like a bargain, but compared to anything you could get from roughly the financial crisis to 2022, 6 percent is a pretty expensive mortgage. You have the federal deficit and debt at least in part to thank for that higher mortgage rate.
Glaeser: Let me echo the supply side of that as well. Boston has many thousands of apartments that have been officially allowed by the city but have not pulled their permits because you have to pay a 1 percent charge to pull your permits. They’re just sitting there because of rising interest rates. The builders, of even these units that have been approved by the city, aren’t willing to go ahead because of the rise in interest rates.
Laine Perfas: OK, so just to be clear, supply equals available homes. Demand equals the people who are wanting to buy those homes.
“You have the federal deficit and debt at least in part to thank for that higher mortgage rate.”
Glaeser: Supply is two things: Supply is both the stock of homes, but it’s also the flow of new homes that are coming in the market. And when we say that the supply is way down, we don’t actually mean that the number of homes is smaller now than it was 25 years ago. We mean that the supply of new homes is radically down and you’ve had a decrease in the amount of new building. To give you an idea of the sort of size of units involved, if we had built between 2000-2020, the same rate that we built between 1980 and 2000, America would have 15 million more homes. That’s how a change in the flow of housing can relate to the change in the stock.
Furman: I wanted to get in a wrinkle about the demand side too, which gets a little bit complicated, which is: Who needs a home? If you are a couple and you have children, you probably need a home. There are a lot of — potentially millions of — pent-up households. The non-technical term for a pent-up household is the adult child living in your basement. Those are people who, in a different environment, might be in their own housing unit but because it’s so expensive and unavailable, they’re staying at home and in your basement. There are all these different concepts and ways of measuring housing shortages but an important part of it isn’t just the person who needs a house. It’s the person who temporarily has given up, has found something else, but in a different world, they probably would be out of their parents’ basement.
Glaeser: Another layer of that is what I call this real estate gridlock, where people are in homes that are not calibrated to their stage of life or their preferences. And we see this a lot with older adults where they’re in maybe too-large homes, but they’re locked into these below-market mortgage rates and they’re disincentivized to sell; also because there aren’t smaller, more age-appropriate options to age-in-place on the market. This kind of missing middle we talk about of duplexes, triplexes, smaller-home types.
Laine Perfas: So just thinking about my situation, I’m married with two young kids living in Boston and trying to even think about buying a home just feels impossible. It’s something we laugh about and we’re like, maybe someday. But I know a lot of people in my demographic who are in the same boat, and there’s this constant debate about whether you just need to suck it up and put all your finances into buying a home or if you should keep renting and just accept that you’re going to be renting forever. It brings me to a question that I’ve had, which is: Is it so bad to rent? Why is it that we have this fixation on homeownership?
Glaeser: No, it’s not bad to rent. It’s important that America have plenty of available rental property. The problem is that — as you know probably better than I do — renting is also pretty darn expensive. The old rule was if you expect to be in the same unit for about seven years, that’s when it made sense for you to switch into owning. Whereas if you expect to be moving around every two or three years, that’s when you should be renting — you should be basing it on that, not on anything else. But as I think about younger people, the way that I think about this is, it relates to a view of the world that Mancur Olson had 45 years ago when he described “The Rise and Decline of Nations” and he described a world in which, in stable societies, insiders figure out how to work the system so that outsiders pay the price. Now, when I read this in the 1980s, I thought, maybe that’s kind of California and New York City, but that’s not most of America where you can still find your future, where they’re still building. Forty years later I think he was incredibly prescient because in fact, the people who own their homes, the rise in housing prices isn’t a problem for them. It’s an increase in the price of their most valuable asset, and they’re benefiting from this stuff. But it’s the outsiders who pay the price. And what’s tragic about the web of local land-use regulations that weigh everything down and make it so difficult for younger people to buy stuff is: America should be a country, as Boston should be a city, for outsiders. And yet we’ve become a place in which insiders get to make the rules and outsiders don’t have a room at the table.
Furman: And that’s one reason the politics are so tricky. If you had a vote on whether the poverty rate would go up or down, I think everyone would say down. If you were to vote on whether GDP would go up or down, everyone would vote up. If you have a vote on whether house prices should go up or down, all of a sudden as a politician, you want to promise one group of people that house prices are going up, you want to promise other people that house prices are becoming more affordable, aka house prices are going down, and unfortunately you can’t really have both of those going on at once.
Tomasso: Speaking as a fellow renter, it’s something I hear a lot among my friends as well, that they could rent something nicer than they can buy right now. And the last few years have seen this multifamily rental housing boom. The reality is that two-thirds of home equity in this country is held by people over 55. There’s a huge skew toward the equity-building potential that comes from homeownership. But at the same time, 50 percent of renters in 2023 were cost-burdened. There’s still a huge issue on affordable rental units. And with cuts to federal funding, especially toward lower-income units, it’s a huge problem.
“NIMBYism, I think ultimately comes down to this fear of change. And the thing is, communities are always changing and they’re growing.”
Laine Perfas: I wanted to go back to something, that was brought up, the idea of insiders versus outsiders. When I was looking into this a theme that comes up often is NIMBYism, Not in My Backyard, and how that attitude can affect regulation and new housing builds. How does that play a role in what we’re seeing?
Glaeser: I first started working on this issue about 25 years ago because Harvard was going to build a contemporary art museum on the banks of the Charles, which Renzo Piano, the Pritzker Prize-winning architect was going to design. There were like three guys whose view of the river this would block, and they managed to get 75 signatures which basically stopped the whole thing. This was amazing to me that a very small number of people could block — not a housing project — but a project that presumably would yield both cultural and economic benefits for all of Cambridge. And this is what NIMBYism is in action — you’ve got your thing, and we’ve created a system in which anyone who abuts can shut down almost anything, with certain modest exceptions, and that yields decisions which run very much against either the needs of the whole metropolitan area or the wider needs of people who aren’t at the table. And part of the problem with the young people who might move into Boston — they’re not at the table at all.
Furman: It also raises the issue of what level of government you work on this issue on. I first started actively working on this when I was chair of the Council of Economic Advisers under President Obama, sitting there in the White House reading papers written by Ed Glaeser and his co-authors. This insider-outsider dynamic really depends on the scale at which you’re doing it. If the people who are making the decision are the people on that block, they’re going to definitely decide against building that because they’re the ones whose views are blocked. If it’s all of Cambridge, maybe you build the art museum, maybe you don’t. If it’s all of Massachusetts, now you have 6 million people who can come to the art museum. At the federal level, all of a sudden you have a much, much broader set of people that benefit. I do think local communities making choices — there’s something important to that, but the political dynamic gets very distorted. If you look here in Massachusetts, the MBTA Communities Act was important because it said, rather than each place deciding whether to build more dense housing, if you wanted to get money to be part of the transit network — and basically most of Eastern Massachusetts is on the transit network — you must build density. And what that said is it passed a law at the level of a state. So if you build more density in Cambridge, it might benefit people who would move to Cambridge from Somerville or Everett or some other place. And rather than just letting Cambridge fully make that decision at the state level, you are letting everyone in the state who might benefit.
Tomasso: NIMBYism, I think ultimately comes down to this fear of change: of property values declining, of infrastructure burdens. And the thing is, communities are always changing and they’re growing. And right now with the affordability crisis across the country, communities are sometimes regressing. When teachers, when small business owners, when grocery store employees can’t live in the community, what kind of community is it changing into? And so I think framing it around that, and just getting practical, is what I found to be the best antidote to NIMBYism.
Laine Perfas: It is interesting to think about how the housing market affects so many things that we don’t always realize are connected. Are there other examples of the ways that the housing crisis is affecting the day-to-day life of local communities and their economies?
Glaeser: Let’s go through the different ways we think that the slowdown in building has changed America. If you look at people who are 35 or 40 in 1983, a lot of them had housing equity. Thirty years later, they don’t. Whereas if you look at people who are 65 to 75, in 1983, not a lot of them had $2 million worth of housing equity. Now, a bunch more of them do, right? You’ve seen a transfer in wealth from the poor to the rich. Two: America is less productive as a country because we don’t build in our most productive places. And so because we don’t allow large amounts of building in Silicon Valley, because we don’t allow large amounts of building outside of New York, and now we don’t even allow it in areas of Miami or Phoenix or Seattle, we are less productive as a country. Third: We are actually worse at carbon emissions than we otherwise would be. If you think about where in America would be the greenest places to locate housing, just greenest intrinsically, it’s coastal California — not because of any environmental regulations, but because of a Mediterranean climate, that means you have to do much less heating in the winter and much less cooling in the summer. If you rank, metropolitan areas by their carbon footprint, adjusting for income and average family size, the cleanest ones are all in coastal California and they’re the most heavily regulated parts of the country. And so these rules are actually making America and the world a dirtier place. We have much less upward mobility, right? The places that are most heavily regulated are also the places where Raj Chetty and his co-authors have identified the most ability to turn poor children into middle-income adults. And so we’ve created a country that is fundamentally more fixed and fundamentally more unjust because of this. We’ve created a country with more housing price volatility. What you see in places where housing supply is relatively elastic is, as housing goes through the cycle, prices stay relatively flat, and it’s the supply of new homes that takes up the slack. By contrast, in places that are more restricted in terms of building, that’s where you see the largest price swings. And it’s precisely that which got us to places like the global financial crisis 20 years ago. When you turn off this crucial market and you stop its ability to flexibly respond, you just end up with an America that’s much less productive, much less fair, much less open, much less green, and much less safe against all sorts of fluctuations.
Laine Perfas: Given the tensions that we’re seeing between the inequity in homeownership and just the unaffordability across the board, it seems that that would be a perfect place for innovation to happen, for creative minds to come together and think of creative solutions. What is preventing that from happening?
Furman: I actually think that is happening. We’ve talked a lot about interests. Some people have an interest in prices going up. Some people have an interest in prices going down. Some have an interest in stopping building. Some don’t. Ideas also matter. The research that Ed has done for decades has persuaded a lot of people. When I was in the White House, it persuaded me and it changed some of the policies that President Obama did. But on this issue, it’s also become a cultural movement. There’s NIMBYs, but there’s also YIMBYs: Yes in My Backyard. Some of them have read all sorts of papers. Some of them maybe just read the book “Abundance” by Ezra Klein and Derek Thompson that popularized a lot of these ideas, but it’s become almost a cultural attitude. The solutions themselves are not that difficult. It’s make it easier to build, make it easier to get a permit, have fewer restrictions on how high you can build, have fewer restrictions on parking. None of that is complicated. But understanding just how beneficial that is for not just the immediate issue at hand, which is affordability, but as Ed was talking about before, for economic growth, for opportunity for mobility in a way that gets people excited and motivated. There’s a lot of interest here. I’ve spent a lot of time over the last decade in despair about how slow the progress has been. Recently progress has speeded up quite a lot and ideas and research and its translation really deserves a lot of the credit for that happening.
“In the U.S. every little community has its own rules. And everything is bespoke. If building is going to be bespoke, it’s not going to be highly productive.”
Tomasso: I would totally agree with what Jason just said, that actually there are brilliant solutions and really creative minds working on this. At Ivory Innovations, we’re a nonprofit dedicated to finding and then deploying the best solutions, the most innovative solutions, to housing affordability across the country. It’s a privilege every day to get to see some of these innovations in places like South Bend, Indiana, who created a pre-approved plan set to make it much easier to build missing middle infill housing. That means getting a townhome or a duplex approved and permitted in as little as a day. Or we’re seeing lower offsite construction methods coming online. Also there’s a role for AI and technology, especially in the permitting and feasibility side of things; we’re seeing the coolest and brightest minds and I love talking to them. The challenge is deploying these more widely, especially these context-sensitive solutions. But I will say that I’m actually filled with so much optimism.
Laine Perfas: Jason, we touched on this earlier, but are there other issues that more construction might help solve as well?
Furman: In the United States right now, we have a problem where the percentage of men between the age of 25 and 54 who are working has been declining for 60 years. There are a lot of people who think we can solve this with manufacturing jobs, but the problem is technology means we have fewer and fewer manufacturing jobs each year. Moreover, if you look at it, construction jobs pay more than manufacturing. This has an important angle, not just for people buying homes, but for people looking for jobs, looking for work. These are high-paid good jobs. And just to be clear, I wouldn’t do a make work program where people go out and build houses we don’t need, just to have jobs, but it’s like a double dividend. We actually really do desperately need these houses. We’re getting in the way of building them, and if we stopped getting in the way of building them, we’d also have more jobs for a population that has a harder and harder time figuring out where it will find work with the economic changes and dislocations that we’ve experienced.
Glaeser: On one level it’s incredibly exciting to be at this moment, which people do care about this issue. I want to add just a slight note of caution though, which is let’s face it, we haven’t solved the problem. And the prices are going up, not down. The policy interest and the nonprofit interest is great, but we’re still fighting against the fact that it’s actually getting harder to build in many parts of America. We’re fighting against the fact that technological productivity in this industry has gone backwards for the last 50 years. What local regulation does is it doesn’t just make it harder to build, it makes it harder to build big projects, and so you kill off scale economies from that. It’s very hard when the firms that are making houses have seven people, and they’re making one house at a time. It’s very hard to get them to invest in the kind of research and development technology that happens in normal firms to make things going forward. I’m struck at the difference between America and Japan. Japan also has local zoning, but they have nine nationwide zones. Nine. Any place that has that zone has the same rules. And so they have a thriving prefabricated housing industry precisely because you know that if your house works in Zone A, it’s going to work in Zone A everywhere in Japan. And so that’s a sort of better model in terms of taking advantage of scale economies. Yet, as we know, in the U.S. every little community has its own rules, its own thing. And everything is bespoke. If building is going to be bespoke, it’s not going to be highly productive and it’s not going to see its productivity grow.
Furman: The other caution I inject is recently the good ideas to deal with this problem have grown in attention and interest. The bad ideas to deal with the problem have also grown in attention and interest. Probably the single worst idea is rent control. The Swedish economist Assar Lindbeck once said, in many cases, rent control appears to be the most efficient technique presently known to destroy a city except for bombing. And the logic of that is very clear. When you lower the price of rent, you end up with less building. It’s the exact opposite of increasing supply. It’s decreasing supply. You often end up with a random set of people in terms of who gets lucky and gets that lower rent and who doesn’t. So rent control — temporary is bad, permanent is even worse. That idea has also grown at the same time that the supply ideas that we’re also excited about have grown.
Glaeser: Let me also echo the earlier comment about having a set of insiders who live in inappropriate housing. We find this very much in rent control as well. We see people who are staying in their units, three-bedroom apartments on the upper west side of Manhattan, long after their kids or their spouse is alive; they’re staying in the unit because they can’t sell it. It’s a rent-controlled unit. And so they’re stuck there in place. So this misallocation of person-to-unit is also a big deal with rent control.
Tomasso: I’m curious, Ed, across your career, as you’ve seen, maybe we could say like kick the can down the road a bit, is there something that does give you hope, especially recently, maybe since the pandemic as the housing crisis has intensified?
Glaeser: I think you’re giving me a lot of hope right now, Amy. I’m fundamentally optimistic and as long as we both remember what’s happened over the last 70 years, and we also remember Jason’s warning that there also are bad ideas, I’m with you. We have a chance to do something good, and let’s be hopeful about that.
Laine Perfas: One thing I wanted to spend a little time talking about is most of the conversation has focused on the densely populated areas in which there’s high demand. I’m wondering if there’s a reason why we haven’t made more efforts to incentivize moving out of those high-demand areas. Are there efforts in place to try to make the densely populated areas a little less densely populated?
Glaeser: Yeah, I think the federal government should be neutral about space on these issues. I think it’s a glory of America that we have lots of different density levels, and there’s no sense in which I think that everyone should live in one particular type of area. But there’s a lot to like about dense living. It tends to be relatively low carbon. It tends to have lots of upsides in terms of productivity. Typically as the density in the metropolitan area doubles, per capita incomes go up by about 6 percent. I think having a national policy which pushes away from density feels like a mistake to me, especially since we already have policies to pay for highways. That basically is a large-scale subsidy for people to use our highways, which is also a subsidy for low-density living. Plus, whatever tax benefits we give toward homeownership, that tends to load away from cities and away from dense living.
Laine Perfas: Just to make sure I’m understanding you, you think being in densely populated areas is good.
Glaeser: As someone who wrote a book titled: “The Triumph of the City: How Our Greatest Invention Makes Us…” happier and all sorts of other things …
Laine Perfas: Well, that’s neither here nor there, Ed.
Glaeser: I’m certainly associated with that view. I certainly don’t believe that the federal government should be artificially inducing people to move to cities, but I don’t think the federal government should be artificially inducing people to move away from cities, certainly not more than they already are. And the subsidy of transportation infrastructure that enables lower-density living is already a sort of significant subsidy to lower-density living.
Tomasso: I would add also some of the states that have had the most progressive land-use reforms are actually quite rural. Maine and Montana come to mind. Montana passed sweeping statewide land-use reform called the Montana Miracle because it was so surprising, thanks in part to the governor’s bipartisan taskforce. In Montana there’s 14, basically, menu of options for cities to reform their land use, everything from increasing ADU’s to decreasing lot size. However, it applies to cities greater than 70,000 people. And there are a few other restrictions. It shows that again, there’s this calibration. Same thing in Maine, single-family zoning essentially ended statewide. But while there’s great promise for maybe adding an ADU, accessory dwelling unit, on a 10-acre lot in rural Maine and creating an opportunity for some intergenerational living, the reality is that the infrastructure needs are still quite great in these rural places where maybe there’s not town water, town sewer, maybe there’s not a town. It just doesn’t always create, again, the more affordable, attainable housing. However, in the cases of Maine and Montana, there’s a lot of opportunity for local alignment and local context around how these land-use changes are shaped. And I think there’s a lot of promise there.
Laine Perfas: Earlier in the conversation we talked a little bit about interest rates. I wanted to talk more about how they affect people’s decisions, whether or not to pursue buying a home and not just the interest rate of the moment, but the fact that it could change suddenly.
Furman: I remember a lot of friends of mine in 2022 and 2023, younger friends who needed to buy houses, were saying, “Hey, the mortgage rate is really high. I’m just going to wait a year or two for the mortgage rate to come down, and then I’m going to buy the house.” And I actually told them, “You know what? There are a lot of reasons interest rates are higher. I’m not so sure that if you wait a year or two, you’re going to get any better deal. You might even get a worse deal.” I’ve given all sorts of people advice that ex post didn’t work out. That was, I think, pretty good. So interest rates are high now. For a while we thought it was just because they were trying to fight inflation with the Federal Reserve. Inflation has come down some; it’s not all the way down. But even with the Federal Reserve cutting its interest rates, the interest rates that homeowners actually borrow at haven’t come down very much. Now, as you’re making a choice, the interest rate might discourage you from buying. But then it leads more people into renting and drives up the cost of renting too. So for any individual, you want to take that interest rate into account in making choices, but it’s not like the problem is solved by us collectively shifting over to renting because the market as a whole ends up suffering for it too.
Glaeser: Just since you’re looking for individual advice, a couple of things on timing your housing market purchase. There’s a lot of volatility in housing prices. And so if you know you’re going to buy, you’re going to buy sometime in the next three years, you probably don’t want to delay because you think you’re going to time something on interest rates that’s going to be smart because you’re adding in lots of extra risks to what the price is going to be by delaying. And that’s probably a bad thing if you know you’re going to buy or not. Whereas delaying because you think you’re going to market time is unlikely to be wise, delaying because you want to be picky about getting a lower price? That’s actually probably smart. Whether or not you are selling your home or buying your home, you don’t want to let your real estate agent push you into moving today as opposed to giving it another six weeks to find a better price product. And so those are all sort of things which are the received wisdom of the real estate economics community around timing your purchase.
Laine Perfas: While we’re on the topic of advice, is there any other advice that people should be thinking about if they are thinking about taking the plunge into homeownership or maybe already own a home, but are looking to sell and buy a different home?
Tomasso: We’re seeing a lot of new models that are changing the landscape of homeownership. Co-buying is increasingly popular. There are platforms that are helping with joint homeownership. Fractional paths to homeownership. And also community land trust is a different model where the land is owned by the land trust, so greatly decreases the overall cost of the home. These are just a few of many — but they’re providing paths to homeownership that are more attainable. They might take longer. They might look a little different, but they’re getting to the same end result. And then the other thing I love is the potential for missing middle infill housing, especially for owning part of a home, owning a unit in a triplex or a duplex, renting out the others and that as a path to equity-building over time.
Glaeser: I will give one piece of advice that I think I’ve had for 20 years, which is, yes, owning a home is an investment unquestionably, but you fundamentally shouldn’t count on getting outsized returns from that investment. And that investment can go up as well as down. And you should be buying a home because you want it as the stage on which you will play out your life. And you should be buying it because it is a fit for what you are and the way that you want to live your existence. You should not think as investors did in 2005 and 2006, that “Oh boy, I’m going to get rich by buying houses.” So just be smart about it. Be smart about thinking about the level of house that you can afford. Think about all of the costs that are going to go on. People typically underestimate lots of different pain points about neighborhoods and I think often they overestimate the niceness of a shiny new structure relative to the fact that this place adds an extra eight minutes every time you want to go to the supermarket. Just think about all the pain points that might not be obvious. And remember, you are in a market where you’re dealing with people, particularly your agent who’s trying to make a sale. And that doesn’t make them bad people, that makes them normal people. But you want to be aware that there’s a person who’s trying to get you to make a sale. So be smart about that psychologically.
Laine Perfas: So this is my last question and I’d love for each of you to answer it: When you dream about a future that has cracked this housing nut, what do you see?
Furman: Personally, just a greater degree of freedom for people to be able to live out their dreams and live their lives. And that freedom, for the most part, involves government to stop restricting the freedom to build larger things, build where people want, and build where people want to live. And so there’s all sorts of places where I’m in favor of more government regulation. In fact, in general, there have been probably more debates where I’ve been on the pro-regulatory side than anti-regulatory side. but this is a place where regulations are really not about protecting the average American. They are about protecting a small group at the expense of others. And so less regulation, more freedom is, for me, the ultimate goal in terms of housing and letting people live out and fulfill their dreams.
Tomasso: I’m an urban planner at heart, so while, yes, we need 2 to 4 million homes by different estimates, I also think a lot about where those homes are located, how they’re accessed from a transit perspective, and who is welcome there. And so my vision for, let’s say, 20 years for housing is really more comprehensive of walkable, livable neighborhoods that are amenity-rich, that are built with climate resiliency and durability in mind, and also that are mixed-income and community-oriented. And while, yes, of course there’s a policy side of things — there’s the more flexibility, streamlining, and the rules around how housing gets built — if I could wave a magic wand, I would change land-use from majority-zoned for single-family-only homes in the country to majority-zoned for multifamily duplexes, townhouses, even cottage clusters. My ultimate vision is really around community and housing as a really important element, but not the only element of community.
Glaeser: I guess I dream of a case in which a young family like yours can come to any metropolitan area in America and find a reasonable place to live that you’re excited by, where you can send your kids to reasonable schools and you’re not spending 50 percent of your income on dealing with your housing. I guess that’s what we’re dreaming about. I want to highlight something that’s fundamentally different between the planner or the architect’s perspective and the economist, which is, fundamentally, we believe in the virtues of choices. I think it is a glory of America that we have different types of communities, and I think there needs to be more, right? I want to see more experimentation, I want to see more different types. I just think we should be open to lots of different types of building and open to the genius that so often exists in American spaces that will find ways for families of the future to find the life that they dream of.

‘Truth is rarely found in echo chambers’Faculty, staff, and students explore what it takes to connect across difference at Community and Campus Life forum
Faculty, staff, and students explore what it takes to connect across difference at Community and Campus Life forum
Most people find disagreeing unpleasant and try to avoid it. But sometimes it’s necessary and can lead to better solutions, or at least a more productive exchange of ideas. The question is: how to remain receptive and avoid the pitfalls of anger and defensiveness?
Faculty, staff, students, and administrators explored this predicament over three days of virtual and in-person lectures and workshops at a March 23-25 Community and Campus Life forum, “Leading With Community.”
“I want each of us to leave with at least one concrete practice that you will try to do differently in your corner of Harvard, in your own lives, or in the world,” said Sherri Ann Charleston, chief community and campus life officer, on the forum’s second day. “You’re going to have a chance to lean in, to hear from your colleagues, to engage in conversation, to try new approaches to building connection across differences.”
President Alan Garber said building skills to work through disagreement is about more than self-improvement. It also speaks to the University’s central mission, noting that “sustaining our academic excellence and nurturing our campus culture are not separate goals.”

“Truth is rarely found in echo chambers,” he said. “Many of the most profound breakthroughs in our understanding of the world and of humanity did not come from consensus. It came from individuals who dared to challenge orthodoxy … If we hope to continue making profound breakthroughs, we must have a community culture that genuinely welcomes the expression of a wide range of views, rooted in different backgrounds, interests, and beliefs.”
Helping the audience develop practical strategies for dealing with diverse views was Julia Minson, professor of policy at the Harvard Kennedy School and a behavioral scientist whose first book, “How to Disagree Better,” was released on March 24, the day she spoke.
Minson began her talk by pointing out an inherent tension.
“There is a huge behavioral science literature that says disagreement is good for us, right? When we are really thoughtfully engaged with opposing perspectives, we make better decisions,” she said. When multiple perspectives are taken into account at once, companies are better at forecasting future events and retaining employees. Conflicts are less likely to spiral out of control.
“When we are really thoughtfully engaged with opposing perspectives, we make better decisions.”

“On the other hand, we hate it, and we try hard to avoid it,” Minson said. “Most regular people tend to not want to engage with views that are dramatically different from their own.”
Throughout her talk, Minson debunked common ideas about disagreement.
For example, when we talk to someone who belongs to a group whose views are in opposition to our own, we tend to believe that person’s views are much more extreme than they actually are. We also believe their views are more simplistic, and we overestimate that person’s level of animosity towards us.
Minson provided some strategies for having more productive disagreements based on her research.
People tend to put a lot of emphasis on their mindset or body language when entering a difficult conversation, but the person on the other side often fails to register — or misinterprets — those cues, she said.
Instead, her research found specific tactics that make the other person feel more respected and heard. A good way to remember them, she said, is to think of the acronym H.E.A.R.: hedge your claims, emphasize agreement, acknowledge other perspectives, and reframe to the positive.
When it came to having better conversations, Minson encouraged attendees to pay less attention to projecting the correct feelings or cues and more to implementing these concrete behaviors.
“It’s relatively easy to train, because we’re not talking about years of therapy,” she said. “We’re talking about: ‘Memorize these words.’”
She broke the audience into groups of three, each with one person assigned to be difficult, another asked to be unfailingly accommodating, and a third to keep track of how many H.E.A.R. phrases the accommodating people used in response to their disagreeable interlocutors.
At the end of the exercise, one attendee said that as hard as she tried to instigate, her partner’s unflinching receptivity and search for common ground made it difficult to remain contentious.
It’s not a rare outcome, Minson said. With some practice, anyone can defuse acrimonious conversations and create reasonable ones instead.

It’s no longer necessary to know how to code to design a website or an app. Describe in plain English what the program should do, and an AI agent will do its best to enact the vision — a process termed “vibe coding.” The end result may have plenty of limitations, but it will be far more advanced than what someone without fairly significant technical skills could produce.
Among those exploring the new practice is Karen Brennan, Timothy E. Wirth Professor of Practice in Learning Technologies at the Harvard Graduate School of Education, who taught a six-week course on vibe coding beginning late last fall. In this edited interview, Brennan details what she tells students and insights she’s gained about what our future with AI may look like.
What is vibe coding, and what was your first experience with it?
Vibe coding is creating software with the assistance of AI — and specifically, creating software where you don’t necessarily understand the code that’s being produced. (“Vibe coding” is a term popularized by computer researcher Andrej Karpathy in February 2025.)
Responsibility for understanding the underlying code differentiates professional software development, which is also increasingly AI-assisted, from vibe coding. As a term, vibe coding can be positive or pejorative, either celebrating the freedom from having to understand code or underscoring the risks of setting aside that responsibility.
My first experience with vibe coding was in December 2024. Through a Harvard Initiative for Learning & Teaching-funded research project, I had been studying how students were using generative AI in self-directed projects, and one of the students introduced me to v0 (an AI-powered tool for building web applications and sites).
When I later needed to build a website for the same research project, I used v0 to build it. I was amazed by how quickly I was able to create the site and by the quality of what was created.
You’ve taught a course on vibe coding, with no prior experience with AI or coding required. What was your hope for the course, and how did it turn out?
My doctoral student Jacob Wolf and I designed a six-week course about vibe coding that we taught in late fall last year, which was supported by a phenomenal teaching team. Our hope for the course was to explore this particular sociotechnological moment, where anyone can (in theory) create software in collaboration with AI.
The central question motivating the course was: How do we think about AI as a creative partner? We had a different theme each week (build something that tells a story, that makes your life easier, that invites play, etc.) and tried different vibe coding tools each week (e.g., Replit, Figma Make, Claude Code).
“The central question motivating the course was: How do we think about AI as a creative partner?”
The course was explicitly not about building professional software; we were focused on experimenting with new creative possibilities.
An important part of the course design for us was pairing hands-on creation with a critical perspective. Each week we read one classic text from computer science (to remind ourselves that people have been thinking about the opportunities and challenges of AI for several decades) and one more contemporary critical piece (to defend against AI hype).
We asked students to put their hands-on experiences and the readings in conversation with each other in a culminating position portfolio. Now that they’ve had all of these experiences, how do they feel about creating with AI? What do they want to say about it?
I loved the experience — both for what our students were able to create and critique and for having the opportunity myself to create together with the students. Ninety-two students participated and based on the course evaluations and our meetings with them, students appreciated both the opportunity to build things for themselves and the critical frameworks we brought to that work.
This was a giant experiment, and as with any first-run course there were many things we were figuring out in real time, especially given ongoing technology changes. But I feel that the positive feedback we received from students affirmed that it isn’t too soon to try teaching this in a university setting at a school of education.
What are some of the promises and limitations of vibe coding?
The core promise for me is democratization of creation. Vibe coding makes the production of software, the output of code, accessible to more people. You can have an idea and realize that idea without having a degree in computer science or hiring a team of developers. And so it is changing the economics of experimentation: to understand a thing, you often have to build a thing, and now you can build that thing very quickly. That rapid iteration and tinkering is one pathway to generating more ideas and unlocking creativity.
Being at a school of education, there’s also a learning dimension that I find exciting. Even though vibe coding can be a way of avoiding CS content knowledge, many of these tools create opportunities for you to inspect and examine the implementation, the code. You can peek under the hood!
And you can also ask the AI to explain what you’ve created together at whatever level of detail you feel most comfortable with, from a more technical explanation to asking it to explain it to you like you’re a first grader.
There are, of course, a number of limitations. Environmental impact and cost were two of many concerns we grappled with. And as a creator, you are limited by your ability to express your ideas in natural language. Students with CS knowledge or design backgrounds can go further because they can more explicitly describe what they’re hoping for.
We saw students get stuck in frustrated loops: prompting AI for something, AI producing something not quite right or something that felt generic, and then students being unable to fully articulate the problem and what to change. Vibe coding privileges people who are strong verbal communicators, which is an important equity consideration.
How does vibe coding differ from conventional software engineering?
Vibe coding is wonderful for quick prototyping and personal projects, which professional software engineers also do.
But I think a major difference concerns responsibility. When I think about my own preparation in computer science, there were very good reasons we were required to take courses on the social impacts and ethics of computing. Vibe coders don’t typically need to concern themselves with the same types of questions that professional software engineering teams are considering, such as reliability, safety, security, and maintainability.
“Vibe coding is often optimized for how much wow can I get in the next hour, rather than for the quality of what’s created or for the people who might depend on it.”
Vibe coding is often optimized for how much wow can I get in the next hour, rather than for the quality of what’s created or for the people who might depend on it.
As someone with a background in computer science, how does your experience with vibe coding differ from someone who has never coded before?
Content knowledge has its advantages! You might have a different sense of what is possible to create. You can more explicitly describe what you’re hoping to create and more easily recognize when something has gone awry and how to fix it. I think there are also habits of mind cultivated through the discipline (i.e., persistence and willingness to iterate) that feel especially helpful when vibe coding.
But more than the differences, what I noticed in the course was how much we had in common, no matter one’s prior experience and expertise. There is something profoundly joyful about having an idea, bringing it into the world, and sharing it with others — and experiencing that surprise and delight together.
How do you see vibe coding evolving moving forward?
I hope that more people have opportunities to experience vibe coding, creatively expressing themselves and opening up new opportunities for learning. I especially hope that we’ll see it more in schools, though there will be challenges due to cost, resistance from lack of familiarity, and understandable concerns about potential impacts on cognition and critical thinking.
Vibe coding doesn’t exist in a vacuum — its uptake in schools (and beyond) will be shaped as much by politics, policy, and people as by the technology itself.
I think the central practices we develop when vibe coding — thinking creatively about what we want to make, composing and iterating on prompts, critically evaluating what is produced — are going to become central life practices. Maybe it’s less “vibe coding” and more “vibe everything.”
If the technologies that surround us will be able to do an almost limitless number of things for us, and we just have to know how to ask, then being able to imagine possibilities, express clearly what we want to see in the world, review what we create, and iterate, will be incredibly helpful capabilities for all of us to develop.
A world-shifting moment (literally)Geoscientists track when Earth went from ‘just another planet’ to ‘something very special’
Geoscientists track when Earth went from ‘just another planet’ to ‘something very special’
The history of the Earth is written on the great tablets of tectonic plates.
The motions of plates shaped land masses, formed oceans, and created the varied climates and habitats that set the stage for evolution and the diversity of life.
But this grand drama begins with a deep mystery: Just when did the continental and oceanic plates begin to drift? Did the lithosphere begin to move soon after the formation of the Earth 4.5 billion years ago or only in the last billion years?
A new study by Harvard geoscientists shows the oldest-yet direct evidence of plate movement about 3.5 billion years ago. In a study published recently in Science, the team showed that plate movements — though not necessarily the modern type — shaped the early history of our planet.
“There has been a huge range of ages suggested for timing,” said lead author Alec Brenner, Ph.D. ’24, who conducted the research in the Department of Earth and Planetary Sciences in the Kenneth C. Griffin Graduate School of Arts and Sciences. “With this study, we’re able to say 3.5 billion years ago, we can see plates moving around on the Earth surface.”
The new revelations came from some of the oldest well-preserved rocks in the world, the Pilbara Craton in Western Australia, which contains formations from the Archean Eon, a period from 4 to 2.5 billion years ago when the Earth was hosting early microbial life and under bombardment by astronomical objects. The Pilbara area contains evidence of some of the earliest known life, stromatolites and microbialite rocks deposited by single-celled organisms such as cyanobacteria.
A team led by Professor of Earth and Planetary Science Roger Fu has been conducting research in East Pilbara since 2017. Fu specializes in paleomagnetism, a branch of geophysics that examines changes in the Earth’s magnetic fields to reconstruct the early history of the planet. Last year, the team published a paper about an ancient meteor impact at the same site.
In addition to revealing the properties of the Earth’s magnetic field, paleomagnetism can also be used to track the motions of plates. By analyzing the magnetic signals of ancient mineral grains, the researchers can infer the orientation and latitude of the rocks at the time of formation — thus using the ancient samples like paleo GPS units.
“Almost everything unique about the Earth has something to do with plate tectonics at some level.”
Roger Fu
“Almost everything unique about the Earth has something to do with plate tectonics at some level,” said Fu. “At some point, the Earth went from something not that special, just another planet in the solar system with similar materials, to something very special. A very strong suspicion is that plate tectonics started Earth down this divergent track.”
In the new study, the researchers analyzed more than 900 rock samples collected from more than 100 sites scattered across an area called the North Pole Dome.
They extracted cylindrical samples, or “cores,” using an electric drill with a hollow bit and diamond teeth, kept cool by a hand-pump garden sprayer. Afterward the position of the sample was precisely recorded with an instrument inserted into the hole containing a compass and goniometer (a device for measuring angles).
Back at Harvard, the cores were sliced into sections like cookies, lined up on trays, and placed in a magnetometer, a machine that can measure magnetic signals 100,000 times fainter than a compass needle. The samples were repeatedly measured while being heated to progressively hotter temperatures up to 590 degrees Celsius until the magnetite minerals lost their magnetization. The step-by-step heating allows researchers to isolate magnetic signals from different periods in the rock’s history. All told, the analysis took about two years.
“We took a really big gamble,” said Brenner, now a postdoc at Yale. “Demagnetizing thousands of cores takes years. And boy, did it pay off! These results were beyond our wildest dreams.”
In ferromagnetic minerals, the orientation of the electrons serves like a compass needle pointing toward the magnetic pole. The electron orientation also provides hints about the position on the 3D globe relative to the magnetic pole when the rock formed, providing an indication of latitude.

By analyzing a series of rocks spanning 30 million years just after 3.5 billion years ago, they found that part of the East Pilbara formation shifted in latitude from 53 degrees to 77 degrees — a drift of tens of centimeters annually over several million years — and rotated clockwise by more than 90 degrees. Within about 10 million years, the motion slowed, followed by a period of little motion.
To compare this movement with Archaean sites elsewhere, the researchers examined a contemporary site in South Africa, the Barberton Greenstone Belt. Previous paleomagnetic studies showed that the latter was located near the equator and nearly stationary during the same time interval. Apparently the two distant regions had different patterns of drift.
In the modern world, the North American and Eurasian plates are moving away from each other by about 2.5 centimeters, or 1 inch, per year.
Lids, ‘dynamo action,’ and more
It remains an open question when and how the Earth took on its current form of plate tectonics, which geophysicists call an “active lid.” Various theories posit that the early Earth had a “stagnant lid” (a single unbroken global plate), a “sluggish lid” (slowly moving plates), or “episodic lid” (plates moving sporadically). The new study rules out a stagnant lid but cannot distinguish which model of plate movement was most likely; the Fu team is pursuing additional studies to answer this question.
“We’re seeing motion of tectonic plates, which requires that there were boundaries between those plates and that the lithosphere wasn’t some big, unbroken shell across the globe, as a lot of people have argued before,” said Brenner. “Instead, it was segmented into different pieces that could move with respect to each other.”
The team also discovered the oldest-known case of a geomagnetic reversal — a phenomenon in which the magnetic field of the planet occasionally flipped. After a reversal, a compass needle would point south instead of north.
This phenomenon is believed to be governed by the “dynamo action” involving the convection of molten iron in the Earth core that produces electrical currents and magnetic fields. The last reversal occurred about 780,000 years ago.
Fu said the new evidence suggests that 3.5 billion years ago, reversals occurred less frequently than in more recent history. “It’s not by itself conclusive, but it suggests that maybe the dynamo was in a slightly different regime than today.”
Writing us back from the brinkResearcher shares insights on letters exchanged by Kennedy and Khrushchev during Cuban Missile Crisis.
Researcher shares insights on letters exchanged by Kennedy and Khrushchev during Cuban Missile Crisis
For Dmitry Yakushkin, the Cuban Missile Crisis of 1962, a confrontation that brought the U.S. and the Soviet Union to the brink of nuclear war, remains an ideal case study of conflict resolution.
Yakushkin, who worked as press secretary for Russian President Boris Yeltsin from 1998 to 2000, spoke Wednesday at the Davis Center about the lessons of the crisis, sharing highlights from his upcoming book based on negotiations between President John F. Kennedy and Soviet leader Nikita Khrushchev.
The two leaders exchanged 10 letters during the 13-day confrontation, from Oct. 16 to 28, including a six-page dispatch from Khrushchev to Kennedy. The crisis ended when the Soviets agreed to remove missiles from Cuba in exchange for a U.S. promise not to invade the island and a secret pledge from Washington to remove U.S. missiles from Turkey.
“We’re talking about political leaders who were moved by an enormous sense of responsibility and fear for the world,” said Yakushkin, whose book was born out of a course on conflict resolution that he now teaches at the University of Tel Aviv. “Their interaction proves that you can talk yourself out of everything if you put in the effort … It’s better to start talking than firing because after firing, it will be much more difficult, in some cases, maybe even impossible, to talk.”
“We’re talking about political leaders who were moved by an enormous sense of responsibility and fear for the world.”
In the moment, Khrushchev sought to maintain the image of a strongman, said Yakushkin, but the Soviet leader would later share his worries for the fate of humanity in books written by his son Sergei. For his part, Kennedy had been vocal about his hope to prevent a nuclear war.
“Mankind must put an end to war — or war will put an end to mankind,” he said in a 1961 speech before the United Nations.
It would be months before the U.S. and the Soviets would sign a hotline agreement, in June 1963; as the crisis unfolded, no direct line of communication existed between the two countries.
Nikita Khrushchev and John F. Kennedy.
“It sounds crazy for a modern audience, right?” Yakushkin said. “Time was precious, and yet they couldn’t call each other.”
To further complicate matters, Kennedy and Khrushchev had to deal with the seven-hour time difference between Moscow and Washington, as well as the delay created by the need to translate their correspondence. Yakushkin noted a possible silver lining: The circumstances of the negotiations may have prevented a quick reaction from either superpower, which could have escalated the crisis to a point of no return.
In studying the letters between Kennedy and Khrushchev, Yakushkin found parallels between the two leaders despite their different backgrounds and ideologies. Both had war experience — Khrushchev served as a political commissar during World War II, while Kennedy fought in it — and both lost loved ones to the conflict. And both leaders were curious about the world beyond the demands of their offices, Yakushkin said. The letters contain comments about family and vacations and are marked by a common humanity, which might have played a role in the resolution of the crisis.
“Both Kennedy and Khrushchev were the products of different societies, and yet they shared a lot of things in common,” said Yakushkin. “In their letters, they revealed themselves as human beings.”
He added: “Everything pushed them … not to resolve the crisis and somehow, they managed to do it … In terms of world politics, that may seem simplistic, naïve, or sentimental, but in today’s atmosphere, for me, the human factor is important. Even in decisions like starting a war or sending troops, the human factor in each person is very important, and that’s what, for me, was precious in this story.”
Two new Corporation membersSylvia Mathews Burwell and Michael S. Chae to join governing board

Sylvia Mathews Burwell ’87 and Michael S. Chae ’90 will join the Harvard Corporation as its two newest members, the University announced Tuesday.
Burwell, formerly the president of American University, secretary of the U.S. Department of Health and Human Services, and director of the Office of Management and Budget, has served in a variety of leadership and advisory roles across government, philanthropy, and higher education. She is currently president of the Board of Overseers until her term expires in May.
In a message to the Harvard community, President Alan M. Garber and Senior Fellow Penny Pritzker noted Burwell’s dedication as an alumna and her deep knowledge of the University.
“Sylvia is known for her integrity, thoughtfulness, and data-informed decision-making, as well as her ability to engage constructively with stakeholders across political and ideological lines,” said Garber and Pritzker.
A widely respected leader in global finance and investments, Chae is vice chairman and chief financial officer of Blackstone, the world’s largest alternative asset management firm. He also serves on the board of the Harvard Management Company.
“A deeply devoted alumnus, [Chae] has supported undergraduate financial aid and the work of the economics and government departments, as well as other significant University initiatives,” said Garber and Pritzker.
“An expert in the management of complex financial institutions with deep knowledge of corporate governance, Michael is widely respected for his collegiality, humility, and rigor.”
In accordance with the University’s charter, Burwell and Chae were elected Monday by the Corporation to become Fellows of Harvard College, with the consent of the University’s Board of Overseers.
Both will begin their service on July 1, filling two of three vacancies arising when Kenneth I. Chenault and Karen Gordon Mills conclude their service at the end of June and following the departure of Biddy Martin, who completed her service earlier this year.
Garber and Pritzker shared their appreciation for the three departing members of the Corporation, noting the ways in which their “pragmatic and principled counsel have helped to guide the University during an extraordinarily tumultuous period.”
“We are grateful to them — and to our colleagues past and present — for all of their work to ensure that Harvard continues to thrive,” they said.
Sylvia Mathews Burwell
Burwell’s career has been marked by a consistent focus on expanding opportunity and strengthening institutions that serve the public good. A native of Hinton, West Virginia, she graduated from Harvard College with a concentration in government and went on to study philosophy, politics, and economics at the University of Oxford as a Rhodes Scholar.
As the 15th president of American University, she helped shape a university-wide strategy for teaching, research, and community engagement, led a major fundraising campaign in support of that work, and guided the institution through the disruptions of the pandemic, balancing health and safety while maintaining academic continuity and student support.
As secretary of Health and Human Services from 2014 to 2017, Burwell oversaw a vast portfolio that included major public health agencies and programs affecting hundreds of millions of Americans, from health insurance coverage to medical research and food and drug safety. She had previously served as director of the Office of Management and Budget, where she was responsible for developing the federal budget and helped negotiate a bipartisan budget agreement following the 2013 government shutdown. Colleagues across these roles have praised her command of detail, calm leadership under pressure, and her ability to build trust among diverse stakeholders.
Burwell also held senior posts at two of the world’s largest philanthropic foundations. At the Bill & Melinda Gates Foundation, she played key roles in both operational leadership and global development efforts aimed at improving health and reducing poverty. She later led the Walmart Foundation, directing philanthropic initiatives focused on strengthening communities, improving economic mobility, and supporting sustainability initiatives.
A member of the Board of Overseers since 2023 and its president since 2025, Burwell also serves on a range of boards and advisory groups in the health, policy, and corporate sectors.
“I am honored to have the opportunity to serve Harvard, an institution that has changed the lives of so many through excellence in its core mission of teaching and research,” said Burwell. “From my upbringing in a small town in West Virginia as a second-generation Greek immigrant to my professional roles, I have personally seen the life-changing impact Harvard offers to people here at home and around the world. Pursuing my educational dreams at Harvard prepared me for life’s opportunities, adventures, and challenges, as it continues to do for so many students today.
“Harvard’s research saves lives and makes vital progress on conditions from diabetes to dementia. I humbly look forward to working with my colleagues to support President Garber, the faculty, and the staff in delivering on that core mission with excellence and with the values of free inquiry, viewpoint diversity, academic exploration, and respect and belonging for all members of our community. I hope to be a part of taking that mission and those values into a better future for society that is both challenged and changing.”
Michael S. Chae
During his nearly three decades at Blackstone, Chae has helped steer the firm’s evolution into the world’s largest alternative asset management firm. As vice chairman and chief financial officer, he oversees the firm’s financial strategy and plays a key role in shaping its long-term direction. He is a member of Blackstone’s management and operating committees and many of its investment committees, giving him broad insight into the firm’s activities across businesses and regions.
Earlier in his Blackstone career, Chae held a series of senior positions in the private equity business, including responsibility for international private equity, leadership of Asia Pacific private equity based in Hong Kong, and as a senior partner in the U.S. private equity business. He has led or overseen numerous investments and has worked closely with portfolio company boards and management teams on strategy, performance, and governance — experience that has underscored his focus on building resilient enterprises and sustaining long-term value.
A magna cum laude graduate of Harvard College, where he concentrated in history, he later earned a master’s degree in international relations from Cambridge University and a J.D. from Yale Law School, where he served as managing editor of the Yale Law Journal.
He has remained an active Harvard supporter and adviser. In addition to serving on the board of the Harvard Management Company, he is a member of the Faculty of Arts and Sciences Dean’s Council and the Committee on University Resources, and has supported undergraduate financial aid and academic initiatives in the social sciences.
Chae’s commitment to education and opportunity extends beyond Harvard. He serves on the board of the Robin Hood Foundation, a leading anti-poverty organization in New York City, and has held governance roles at several educational institutions, including chairing the board of the Lawrenceville School. At Yale Law School, he and his wife, Alexa, established the Chae Initiative in Private Sector Leadership. He also serves on the board of the Asia Society and as a member of the Council on Foreign Relations.
“I am honored to serve an institution that means so much to me, at a time when it faces both historic challenges and opportunities,” said Chae. “Harvard’s mission of excellence in learning and research has never been more vital, as is the importance of fostering and protecting a culture of academic freedom and intellectual diversity.
“I look forward to working with the University’s leadership and the Corporation’s members to help Harvard fulfill this critical mission.”
The Harvard Corporation, formally named the President and Fellows of Harvard College, was chartered in 1650 and exercises fiduciary responsibility with regard to the University’s academic, financial, and physical resources, and overall well-being. Chaired by the president, the 13-member Corporation is one of Harvard’s two governing boards. Members of Harvard’s other governing board, the Board of Overseers, are elected by holders of Harvard degrees.
‘Old’Rethinking what it means to age as humans live longer and healthier
Rethinking what it means to age as humans live longer and healthier

A series about meanings
An American born in 2024 can expect to live to 79. That’s up 0.6 years from 2023 and the longest life expectancy in U.S. history.
But living longer and living well are not the same thing. About 93 percent of the nation’s 58 million adults over 65 live with at least one chronic health condition, such as hypertension, high cholesterol, arthritis, or diabetes. After age 55, about 42 percent of Americans go on to develop dementia.
Despite that, an increasingly visible cohort of older Americans aren’t just living longer. They’re also extending their healthspans, the years of life free from age-related illness or cognitive decline. In doing so, they’re creating new models for what it means to age well and challenging some of the oldest cultural assumptions about the last third of life.
For the latest installment of “One Word Answer,” a series focused on connotations, we asked three scholars to dive into “old.”
A historical view of frailty
When Maud Jansen was completing clinical rotations, she found herself troubled by the way some physicians spoke about older patients, as though certain outcomes were forgone conclusions before treatment had even begun.
She recalled a team of doctors discussing an elderly woman with a hip fracture and a stroke. One doctor remarked, “Well, she’ll go to rehab and wither away.”
“It’s thorny, because in a way we have to accept that people get older and might have bad outcomes,” Jansen said. “But then again, are we sure?”
“It’s thorny, because in a way we have to accept that people get older and might have bad outcomes. But then again, are we sure?”
Maud Jansen
Now an M.D.-Ph.D. candidate in Harvard’s Department of the History of Science, Jansen studies frailty — an umbrella term that emerged in the 1980s to describe a set of symptoms, such as hip fractures, incontinence, and delirium, that are common among older adults, and to which older adults are uniquely susceptible because of the cumulative effects of aging. Jansen examines the longer history of medical care for these conditions to understand how assumptions about old age shaped care and medical responsibility for bad outcomes.
Before the 19th century, the dominant view of aging was one of inexorable decay, she explained. Older patients, considered incurable and therefore unworthy of treatments, might be sent to almshouses. A hip fracture was frequently fatal, less from the injury itself than from what followed: prolonged immobility, infection, or neglect.
“What I’m finding as I’m researching these conditions of frailty is that the cultural understanding of people as frail can, and did, naturalize bad outcomes as inevitable. In this way, beliefs about frailty foreclosed the possibility of effective intervention or improvements to care.”
The 20th century brought new frameworks. The Great Depression and the passage of Social Security in the 1930s gave rise to concepts like retirement and the “golden years” — the idea that old age might be a distinct and important phase of life. In 1969, the word “ageism” entered the lexicon to describe discrimination against older adults. A year later, a Philadelphia woman named Maggie Kuhn founded the advocacy group that became known as the Gray Panthers to challenge the idea that it was normal for older adults to simply withdraw from society.
Today, Jansen is delighted by depictions of seniors living active and engaged lives, like older adult influencers sharing their passions for fashion or fitness, or TV shows like Netflix’s “Grace and Frankie.”
“It’s a great thing that older adults are more robust into later life. But then the question becomes, what do you do with it? Has society really carved out good roles for them? I think that’s an ongoing question.”
Luck, lifestyle, and privilege
Jeanne Louise Calment, who died in 1997 at age 122, is the oldest person in history whose age has been verified. Scientists generally accept her age range, 120 to 125, as a hard upper limit — at least for now.
“The median is getting higher and higher while the maximum does not shift,” said William Mair, professor of molecular metabolism at the Harvard T.H. Chan School of Public Health.
Humans could expect to live for 35 years for most of our evolutionary history. It wasn’t until interventions like clean drinking water and antibiotics that we lived long enough to develop chronic age-related health conditions. Now, Mair said, researchers are focused on helping more people get closer to Calment’s age and get there with their health intact.
“Some people have incredible health — centenarians, or people who are super active into their late 90s. That’s not just luck,” said Mair. “Whether it’s optimism or social engagement or nutrition, we can begin to bring these things together and see how they do it.”
The biology of exceptional aging is increasingly legible. Researchers can now measure what they call biological age, which is distinct from chronological age, using markers of DNA damage, metabolic function, and cellular health. Older adults who age well often show the biological profile of someone significantly younger: say, a 95-year-old with the cellular profile of a 75-year-old.
Diet, exercise, sleep, and social connections all appear to influence the rate at which the body ages. So do income, education, and even ZIP code.
In Boston, Mair pointed out, a recent report found a 23-year difference in life expectancy between the neighborhoods of Back Bay and Roxbury, which are barely two miles apart. It’s a stunning gulf, but it’s also an improvement: In 2007, the discrepancy was 33 years.
“Aging is something that you can speed up and slow down through policy, through drugs and genetics, through things like exercise and healthy food,” Mair said. “It doesn’t mean we can all live to 150, but it does mean that there are things we can do.”
Fighting the urge to retreat
Long before patients with Alzheimer’s disease show signs of cognitive decline, they often display behavioral changes, says Nancy Donovan, a Harvard Medical School associate professor of psychiatry at Brigham and Women’s Hospital and the director of the Neuropsychiatry of Aging Research Group. Those symptoms can include irritability, anxiety, sleep disturbances, and a loss of motivation.
This can create a cycle, she said, both for people with Alzheimer’s and for adults with the usual slumps in stamina and strength that accompany even robust older age. Older adults who begin to feel the early effects of cognitive and physical decline often respond by pulling back from the work and social engagements that structured their days.
“People start to decline, and then they withdraw,” Donovan said. “But those things we do in our everyday life actually support our ongoing cognition and healthy aging. Disengagement may precipitate further decline.”
“Disengagement may precipitate further decline.”

The psychological challenges of later life are daunting. Older adults face the loss of friends and loved ones. They must learn to rely on others for care. And they must reconstruct a sense of purpose uncoupled from their professional identities.
“One does have to respond to these various threats to well-being, with the help of your social network and your resources,” she said. “We’re getting inundated with advice for healthy physical aging and healthy cognitive aging, but not healthy psychological aging. What supports a positive psychological transition towards the end of life?”
Donovan’s prescription is an echo of groups like the Gray Panthers. She encourages older adults to fight the urge to retreat. “Amp up your exercise. Pay more attention to your health behaviors. Stay curious and engaged in the world.”
But at age 69, Donovan knows from personal experience that there is something uniquely positive about aging, too. She and her peers are traveling the world, trying new things, and investing in their hobbies. “You can appreciate your life better from the perspective of values and meaning, and this can guide you into late life.
“We’re relishing this period of freedom,” she added. “Many of us have parents who have passed away, so our major caretaking responsibilities have ended. If you still have your health, it’s a peak phase. The years before 75 or 80 can be the best time of life.”
‘Best college tradition anywhere’Smurf-blue hair, chain-mail suits, vuvuzelas, and bagpipes abound as students flood Yard for annual raucous rite of Housing Day

Smurf-blue hair, chain-mail suits, vuvuzelas, and bagpipes abound as students flood Yard for annual raucous rite of Housing Day
On any other day, junior Hugh Mackay’s blasting bagpipes would have been less than welcome outside Hollis dorm so early in the morning.
On any other day, Economics Professor David Laibson might have raised eyebrows prancing in front of University Hall with smurf-blue hair and Mardi Gras beads.
And on any other day, Xavier Ayala-Vermont ’27, attired in an inflatable lion suit, would have been doomed had he summited the statue of John Harvard in the Yard waving a Winthrop House flag — right in front of the Harvard University Police.
But this was no ordinary morning.
Friday was Housing Day, the joyful annual tradition in which students from the 12 College Houses stream into the Yard in a raucous show of pride before splitting up to storm the adjacent first-year dorms and welcome those students with the housing assignments that will shape their residential life over the next three years.
So Mackay’s bagpipes barely registered over the din — bullhorns and Bluetooth speakers, cowbells and clapping — emanating from the west side of University Hall.
Ayala-Vermont got a steadying hand and even a fist bump from the HUPD.
And Laibson, co-faculty dean of Lowell House, whooped it up with his arms in the air, basking in the sort of cheers — “DAV-ID! LAIB-SON!” — that might otherwise greet a Celtics power forward.
“This is a wonderful day for the students to show their spirit and kind of shed the super-academic, super-intense [persona] and just really be fun College students enjoying a little healthy competition,” said Nina Zipser, Laibson’s wife and fellow Lowell House faculty dean, straining over the reggaeton classic “Gasolina” and the bang of a chalk-bomb party popper, which released a plume of yellow dust over the crowd.
Zipser, who also serves as dean for faculty affairs and planning in the Faculty of Arts and Sciences, applied the dye to Laibson before they marched over at 7 a.m. in “a big blue mass” with the Lowell crowd, finding Kirklandians — typically first to the statue — and Winthrop House residents, having pulled overnight statue-side shifts.
Lowell claimed the southwest stairs of nearby University Hall, with some students wielding swords and wearing chain-mail suits with the “Blue Man” House crest, others attired in flannel Lowell pajama pants.
“This is what spirit in your University and your House is all about,” said Danoff Dean of Harvard College David Deming, ostensibly dispassionate (though he betrayed his roots as a former Kirkland faculty dean by bringing bagels to the Kirkland students by the statue at 7:15).
Students rush into a first-year dorm room to announce what House the student will be living in for the next three years.

“It’s not really about the House itself. It’s the sense of community that it builds, the things you do together with your friends,” Deming said. “You don’t get this from having some big corporate dorm where everybody lives or from living off-campus.”
When Adams House arrived, sophomore Tess Straw blitzed the yard in her own crimson-and-gold scarf and a long military dress coat loaned by the House.
The braided-gold epaulets and brass buttons of the outerwear, however, suggested that Straw’s version of John Adams had left the Continental Congress to lead a marching band or perhaps invade Prussia.
“This is fun itself, but it’s a totally different experience to be inside all these housing buildings around us right now, listening to this, knowing your House is going to come get you,” she said, drawing festive Adams-insignia acorns on the ground using a condiment bottle of dyed chalk dust.
As her fellow students hurled slogans back and forth, Straw’s friend Arthur Tao bounded over in a green bodysuit, Leverett House T-shirt, and light-up bunny ears — the rabbit mascot inspired by the hares on the Leverett House shield. The two greeted one another with smiles and goodwill.
Just then, the Mather crew stormed the Yard.
Tao raised a green vuvuzela and blasted the plastic horn in their direction with take-that might, before shrugging it off. “I know Leverett’s the best,” he said.
Regardless of the House, he added, “It’s really cool to see the School come together as a community, because that’s not always common.”
To foster more of that spirit, Housing Day was moved from the Thursday before spring break to the Friday after to relieve the stress of conflicting with midterms and to scaffold more events into a “Spirit Week” without having everyone immediately depart.
That meant not just the late-night food trucks on Thursday and the customary new-House welcome dinner Friday night, but also a dodgeball tournament followed by the second annual “Johnnies” on Saturday. The Oscars-style ceremony honors the best student-made Housing Day music videos, with winners taking home coveted John Harvard statuettes.
In this case the University founder eschews his traditional seated pose to celebrate, as the tagline notes, “videos so good John Harvard stands up for them,” said Harvard College Dean of Students Thomas Dunne, a veteran of several institutions, deeming Housing Day “the best college tradition anywhere.”
Shortly before 8:20 a.m., students started storming the dorms, and soon first-years were converging on the grass to compare notes, hugging and shouting things like, “You got Adams too?! Yeah, baby!”
First-year Olukayode Ekundare wore a big smile.
He had watched the scene from up high in Hollis with friends since 6 a.m. and was thrilled when the upperclassmen finally burst in — “jumping up and down, playing music, bang-bang-bang on the door.”
He was happy to get Currier — but had to dash. It was just past 9, and he was late for a lecture.
