Schlesinger Library’s scrapbook collection offers scholars insights into hidden stories, texture of everyday life in bygone eras

It might come as a surprise that scrapbooks — mundane, somewhat old-school arrangements of photographs, newspaper clippings, greeting cards, and other ephemera — are worth archiving. But the Radcliffe Institute’s Schlesinger Library houses more than 600 of them among its collections.

Scrapbooks can help researchers fill in gaps of history with insights into the lives of ordinary people — sometimes people for whom there is little or no public record. This aspect of the collections is particularly important for the Schlesinger as the country’s leading center for women’s history, because so much of it was thinly documented in official sources.

“Scrapbooks are unique because there never is one singular formula,” says Victor Betts, curator for collections on ethnicity and migration at the library. “They’re a great way to introduce and tell people about hidden and unknown histories.”

Jenny Gotwals, curator for gender and society, said the collection has drawn significant interest among students and scholars doing research for projects, papers and dissertations.

Last spring, Betts co-taught “Asian American Women’s History in the Schlesinger Library,” an embedded course for which students worked with the library’s primary source materials.

Paired with the course was Schlesinger’s recent exhibition, “Illuminate: Contextualizing Asian American Women’s Stories through the Archives,” curated by Betts, which brought to light many marginalized histories.

The exhibition featured a display about the history of Japanese American incarceration, showcasing pages from scrapbooks, autograph books, and photo albums. Each item offers a close look into the lives depicted on the page, lived experiences that are too often forgotten.

“There is an autograph book from Crystal City, one of the camps in Texas, with sketches and signatures and messages from various people who were incarcerated in camps, in English, Japanese, of course, and then Spanish,” Betts said. “Why is there Spanish in this autograph book? There were actually Japanese Latin Americans whose governments, in cooperation with the U.S. government, shipped them to Crystal City; that’s a part of history not a lot of people know about.”

Rooted in the recordkeeping tradition of family Bibles and commonplace notebooks,  scrapbooks have been around since the mid-19th century. Although the format has evolved somewhat over the centuries, few rules govern the contents of scrapbooks.

“The Schlesinger has traditionally called volumes that are just photos photo albums, and volumes that have multiple types of things scrapbooks,” explains Gotwals. But, “what can be in a scrapbook is anything.”

When considering scrapbooks for acquisition, Gotwals and her colleagues ask what can be learned from each item, what histories might be revealed or re-examined.

“Can we tell who made it? Are people [featured] named? Are there dates, titles, a menu from a restaurant? What is it that we can use to build a life story?”

Some scrapbooks and photo albums come to Schlesinger via donation as part of a larger collection, often from a notable source. Many others are one-offs, periodically from less well-known authors, purchased from rare book dealers who find them in thrift stores, estate sales — even dumpsters.

Sometimes, the most valuable insights gleaned from a collection involve what isn’t there.

The scrapbook of Maggie Neyland Chatman, for example, is dedicated to social events like cotillion programming, debutante balls, weddings, and funerals that her family attended between 1940 and 1965. One clipping Chatman saved shows her daughter and two peers, primly dressed and smiling. On the flip side is part of an article, the headline fully visible in bold type: “Is Malcolm X The Real Leader Of The Black Muslims?”

Though the family, who lived in San Francisco, was African American, Chatman’s scrapbook reflects little interest in the Civil Rights Movement — or the Nation of Islam, for that matter (in fact, there were some Christmas cards in the collection). Yet the wider historical backdrop was there nonetheless.

“What’s interesting about an archive isn’t always about what the person does,” says Gotwals. Just as illuminating, if not more, is the narrative they attempt to create.

“What do we make in our life, and what can we learn from it?” Gotwals said. And for researchers: “How do we build knowledge out of these primary sources?”

Archivists like Jess Purkis, librarian/archivist for digital programs at the Schlesinger, give researchers broader access to primary sources through digitization. Each scrapbook brings new challenges: brittle paper, disintegrating newsprint, envelopes pasted to the page with letters still inside.

“Scrapbooks are notoriously difficult [to digitize] because they are so layered,” Purkis said. “There might be a giant bow that’s covering up a bunch of stuff. There might be five greeting cards weighing the entire page down, and you can’t pick it up because it’s so heavy, you’re afraid it’s going to break the page.”

In circumstances like these — which, when it comes to scrapbooks, are extremely common — archivists and digitization assistants prepare materials to be imaged by technicians at Widener Library who use photography and large-format scanners to preserve the material.

The more complex the page, the more complex the instructions. In one project, Purkis had to request that a scrapbook with about 125 pages be imaged 404 times, asking technicians to “[photograph] it as many times as it takes to make visible all of the things on the page that might not be visible if there was just one shot.”

“One of my favorite parts of archiving is when the little foibles or the little bits of personality seep through the cracks of what is formally arranged,” Purkis said. “People are usually putting forth a specific version of themselves in their archives. That’s just human. But every once in a while, you come across something that someone has either kept, or scrawled something on the side of, that’s different.”

The official record can only do so much to describe the texture of a life at a specific point in time. “That’s where a scrapbook and a diary, and love letters come in,” Gotwals says. “They document an experience and a life.”

Berkman Klein researchers unveil new tool to verify identity, let users limit information they share, where it is stored

4 min read

In our increasingly online lives, convenience has come at a cost. 

The average person has more than 100 online accounts, and creating a new one often requires handing over personal information like an email address or a birthdate. 

Researchers at the Applied Social Media Lab at the Berkman Klein Center for Internet & Society say the current system puts your privacy at risk and makes you more vulnerable to identity theft, and they have a plan to fix it. 

As part of a digital identity symposium in April, engineers from ASML launched the Keyring wallet, an open-source identity verification tool. Rather than surrendering personal data to be stored in corporate databases, Keyring lets users keep their information on their mobiles and disclose only what is absolutely necessary to verify who you are. 

“Identity is actually deeply personal,” said ASML principal investigator James Mickens, Gordon McKay Professor of Computer Science at Harvard John A. Paulson School of Engineering and Applied Sciences. “Your age, your name, your location, your gender — all of these are inextricably tied to you as the user, not to some company or some particular piece of technology.” 

“We were handed a problem nobody had solved. We had no UX patterns, no templates, no precedent. And we built something that a real person can pick up and use in seconds.”

Nicole Brennan, senior UX designer

During the symposium, researchers described what they see as an increasingly insecure digital identity ecosystem. Meg Marco, senior director of ASML, said individuals have too much data spread out over too many accounts they don’t fully control. 

“This is important, not only because it is annoying. It is also insecure,” Marco said. She pointed to the 2022 breach of the password manager LastPass’s cloud database, in which hackers obtained copies of tens of millions of users’ encrypted data. 

Keyring, which was developed in collaboration with the Linux Foundation’s Decentralized Trust Graph Working Group, was designed around a user-owned identity wallet where users can share a specific but limited aspect of their identity. That might mean revealing age but not birth date or that they possess an account with a specific email provider without disclosing the username.

To use the wallet, users prove their identity through biometric data such as a fingerprint or face scan, which is only stored on the user’s cellphone. They can also add verifiable credentials like a digital version of a driver’s license or proof of employment. 

Keyring also supports verification of in-person connections without a company operating as an intermediary — for instance, two people who meet at a professional conference could securely verify their identities and confirm they met in person without handing over their data to a service like LinkedIn. 

Each securely verified connection contributes to what researchers call a decentralized trust graph: There is no centralized database of identity data, but each user can be sure of the credentials of everyone in their network. 

“Our hypothesis is that this type of trust graph can help address important challenges in social media, such as distinguishing people from AI agents, providing age assurance or determining the origin of certain content,” said principal engineer Brendan A. Miller.

Nicole Brennan, senior UX designer, said one of the main goals for Keyring ease of use. “We were handed a problem nobody had solved. We had no UX patterns, no templates, no precedent. And we built something that a real person can pick up and use in seconds,” she said.

According to Yajaira Gonzalez, a product leader at ASML, the technology’s main challenge is buy-in from institutions, governments, and corporations, because they would need to issue and recognize verified credentials. Without their participation, the system is limited to peer-to-peer or experimental use. 

“Incentives for all of these entities to join into this model are misaligned,” Gonzalez said, “because currently they do benefit a lot from owning and controlling your data, because at the end of the day, they monetize it.”

Gonzalez said there may be technological workarounds, but her main hope was for a grassroots movement demanding greater agency over user data.

Building useful quantum computers ‘in our direct line of sight’

Researchers say creation of startups suggests game-changing tech may be developing at faster pace than expected

7 min read

Mihir Bhaskar was a self-described “total nerd” in high school. He volunteered at a computer history museum and became obsessed with the hardware and how it all came to be: from abacuses to punch cards, vacuum tubes to personal computers.

“I was really fascinated with the history of computing, the development of the semiconductor and transistors and things like that,” said Bhaskar, who received his Ph.D. in physics from Harvard in 2021. 

Over the past decade, Bhaskar and other grad students, postdocs, and professors have made strides in developing quantum computing, work that one day may land their devices in a museum display. The pace of their progress has already fostered three startups, a sign the game-changing technology may be developing ahead of expectations, researchers say.

“I have never seen a science that is so ‘blue sky’ go out into the commercial sphere so quickly,” said Evelyn Hu, Tarr-Coyne Professor of Applied Physics and of Electrical Engineering. “Where are we now compared to where we thought we’d be in 2018? We are so much farther ahead than I think any of us could have imagined.”

One of the three startups, LightsynQ, was co-founded in 2024 by Bhaskar to commercialize his doctoral research in quantum networking. The company was acquired last year by publicly traded IonQ, where Bhaskar is now senior vice president for research and development.

Another, QuEra, was founded in 2018 by Mikhail Lukin, co-director of the Harvard Quantum Initiative in Science and Engineering, and Markus Greiner, George Vasmer Leverett Professor of Physics, with partners from Harvard and MIT. 

QuEra recently shipped its second commercial quantum computer — based on technology from their Harvard labs — to Japan’s National Institute of Advanced Industrial Science and Technology. 

The third, CavilinQ, launched in order to develop and commercialize another quantum networking technology, is taking initial steps into the market, having announced $8.8 million in seed funding.

Brandon Grinkemeyer, a postdoctoral fellow in physics and, with Shankar Menon, one of CavilinQ’s founders, said that quantum networking is important for the same reason that it is in classical computing. 

The ability to connect many processors together increases computational power and is what makes supercomputers so powerful. The same principle applies to quantum computing, he said, where networking quantum processors enables them to tackle problems that no single processor could handle alone.

“Connecting processors can offer fundamentally new functionality beyond just scaling up,” Grinkemeyer said. “It unlocks capabilities like quantum enhanced imaging and fully secure quantum computation.”

Quantum computers leverage the strange physics that rules in the atomic and subatomic quantum realm, where ones and zeroes — the bits that drive classical computing — become ones and zeros and every value in between.

In addition something called “quantum entanglement” means particles can influence each other even when separated by a great distance.

Harnessing these and other properties at work in the atomic realm has the potential to enable vastly more powerful computers, researchers say, with potentially revolutionary applications in drug discovery, finance, materials science, cryptography, exoplanet research, chemistry, and high-energy physics, among others. 

Hu is co-director of Harvard’s Quantum Initiative in Science and Engineering, from whose affiliated labs key developments have emerged.

Established in 2018, HQI researchers like Hu and Lukin, the Joshua and Beth Friedman University Professor, credit the entrepreneurial environment in and around Harvard with fostering research partnerships with industry, including Amazon Web Services, which in turn has encouraged the development of startups to promote and further develop advances in quantum computing and networking. 

Of particular importance, Lukin said, is improved fault tolerance, a recent advance out of his lab that reduces errors in calculation that are byproducts of the quantum forces at work. Those errors can cascade and render results unusable. 

The advance was reported late last year and has cleared a way for technology to leap beyond where many thought it would be at this stage.

“People initially thought that this sort of fault-tolerant, large-scale, quantum computers would be coming some time by the end of the next decade, and I think it’s quite likely that actually they will be here — at least in some form — by the end of this decade,” Lukin said. “So, we’re at least five, maybe 10 years ahead. And it’s really a lot of the work in the HQI that fueled that.”

“This is completely new technology. A quantum computer is different from any kind of classical computer that’s ever been built,” said Mikhail Lukin.

Bhaskar agreed that the technology has advanced faster than he expected and said that a key element has been industry support.

“I couldn’t have predicted this. I got into the field because I knew there was promise, but the pace of innovation, the pace of development, the pace of — honestly — capital going into the technology has far exceeded what I could have possibly imagined or dreamt of,” Bhaskar said. “I didn’t get into this space to be an entrepreneur, I got into this space because I was really interested in working on the fundamental computing information processing technology and the physics of it. That’s what I love to do.”

Harvard Chief Technology Development Officer Sam Liss said the advances and their early commercialization through startups are a product not just of the drive of the researchers involved and the support from their partners, but also the Greater Boston ecosystem, which he described as a “quantum hub.” 

“It’s an area of research with commercial potential, that’s one aspect of it,” Liss said. “It is a mindset and a culture of entrepreneurship within HQI, and it’s the ecosystem in which we reside. Boston is a quantum hub — this is an area of focus for the region — and that, along with the engagement of supporters and alumni, is making all the difference.”

Liss is also eager to see more quantum research projects evolve into startups, like QuEra, LightsynQ, and CavilinQ. The support and enthusiasm for quantum means that academic discoveries have the potential to become impactful ventures. 

The Harvard Grid Accelerator was created by the Office of Technology Development to do exactly that, offering funding, mentorship, industry connections, and support to help research in engineering and the physical sciences turn into startup companies. Recent support from the Grid Accelerator led to the launch of CavilinQ.

Researchers say some fields will obviously benefit from quantum computing, but some important, even revolutionary, applications may come in areas where they’re not anticipated.

“The transistor was invented in 1947 and initially nobody knew what major application would benefit from its use,” Hu said. “They knew it was important, but it was perhaps too early to identify the ‘killer apps.’ The initial applications were for hearing aids and then later transistor radios.”

While useful, neither of those had the society-shaping force of the computer revolution that was enabled by transistors, which are electronic switches present on modern microchips by the billions.

But those early devices served a useful function: They kicked off the new technology’s commercialization, which got people wondering what else they might be able to do. 

As with the transistor, Lukin said, we may not know until more quantum computers are out there, grinding away at problems, letting people see what they can do and begin to imagine new possibilities.

“This is completely new technology. A quantum computer is different from any kind of classical computer that’s ever been built,” Lukin said. “There are two key challenges in this field. One is building these quantum machines, and the other is using them. While a lot of hard work remains to be done, for the first time, building useful quantum machines is in our direct line of sight.”

The perils of seeking empathy from a chatbot

5 min read

It’s clear that artificial intelligence is changing everything, from the way we learn to the way we work. What’s far less clear is how AI’s insinuation into everyday life is changing the way we relate to each other in the non-digital world.

During a talk this week at the Barker Center, panelists discussed the rapid development of generative AI chatbots, like Claude and ChatGPT, and the ethical implications for how we communicate and connect as human beings.

The event, moderated by Eric Beerbohm, faculty director of the Edmond & Lily Safra Center for Ethics at Harvard, kicked off a series that will consider how AI is transforming both civil and uncivil disagreement.

The panel referenced a now-famous JAMA Internal Medicine article about patients perceiving AI responses to online health questions as more empathetic and accurate than those from human physicians.

Training AI chatbots to seem empathetic in order to boost engagement may be a smart business decision for tech firms, and may be preferred by users, but such constant reflexive validation comes at a cost, said Carissa Véliz, associate professor of philosophy at the Institute for Ethics in AI and a fellow at Hertford College at the University of Oxford.

Chatbots are “the ultimate bullshitters because they don’t care about anything, they’re not truth tracking, and they will say whatever human beings prefer.” The “empathy” as a design feature lulls users into thinking the chatbot understands them and has their best interests at heart when it does not, she said.

“There is no one there on the other side of the screen, there’s no one who cares about you,” said Véliz. “And even to call it empathic, I think, is a mistake. It’s a kind of simulation of empathy, which is very different.”

“There is no one there on the other side of the screen, there’s no one who cares about you.”

Carissa Véliz

The potential for distorted social and cognitive effects from chatbot use, particularly among children and teenagers, is worrisome, she said.

“I think it’s very healthy to experience the frustration of other people. If you’re boring, it’s good to know that you’re being boring. Yes, it’s painful, but it’s valuable feedback,” she said.

Panelists agreed that perpetual validation can lead to an overreliance on AI for emotional support and stunt the development of critical thinking skills, as well as prompt users to hold everyone to the “infinitely patient and sycophantic standards” of chatbots.

“One of the advantages of talking to another human being is that, annoyingly, they disagree with you and they push back, and they don’t see things the same way as you do. That’s very frustrating and incredibly healthy because it grounds you to reality,” she said.

Since ChatGPT’s introduction in fall 2022, chatbots have greatly advanced in sophistication and accuracy, especially in medical diagnostics and laboratory research, said Jonathan Zittrain, George Bemis Professor of International Law at Harvard Law School, a professor of computer science at John A. Paulson School of Engineering and Applied Sciences, and professor of public policy at Harvard Kennedy School.

However, much like antibiotics that may be helpful in the moment, there’s a real danger that the easy availability of medical chatbots can be socially corrosive and instigate a much larger, society-wide problem if we are over-reliant on them, he said.

“It is the poor man’s version of artisanal contact with a human being, and it will provide a crutch so that we never have to provide” real human-to-human interaction, said Zittrain, who is also the faculty director of the Berkman Klein Center for Internet and Society.

Not only do people lose the therapeutic value of personal contact when a medical chatbot is in charge, but it becomes much more difficult to hold anyone accountable when something goes wrong, Véliz noted.

Algorithms, especially on social media, are often used as a barrier to minimize a technology company’s accountability, so it’s important that the question of who’s responsible for a chatbot’s faulty diagnosis or mishandling of treatment gets answered, she said.

Zittrain said while today’s AI chatbots present some risks of diminished interpersonal connection, they also offer immense promise that we shouldn’t simply turn away from out of fear or skepticism.

“I just I think we need to be really gimlet-eyed about just how far functionally these things have come, even if what has gotten them the most distance lately has been parlor tricks strung together,” he said.

If humans could tweak chatbots so they aligned with their long-term goals and helped them stay on track, Zittrain asked, “Would you turn that down, especially in a world where as soon as you leave this building, or if you’re on your phone right now, you’re getting importuned on all corners by people appealing to your momentary impulses?”

Rather than extinguishing our taste for cultural artifacts like books and art, the ubiquity of AI may instead remind us of their value, said Véliz.

“I think that when we look at AI, one of the things that becomes more salient is the beauty and richness and resources of everything that’s not AI — all of the richness of the analog world,” she said.

“No matter how good AI becomes, it will never be analog, and no matter how digital we become, we will never be completely digital. The richness of the natural world, of the cultural world, of paintings, of coffee shops, of bars, of universities, is something that I think we should cherish a lot more and that becomes brighter in light of AI.”

Gift from the Troper Wojcicki Foundation honors the late technology executive Susan Wojcicki

To honor the legacy of the late Susan Wojcicki ’90, a trailblazing technology leader and former CEO of YouTube, Harvard dedicated the Susan Wojcicki Library at the Science and Engineering Complex earlier this spring. The event brought together President Alan Garber, other University leaders, faculty, students, and the Troper Wojcicki family.

Named in her memory through a $20 million gift from the Troper Wojcicki Foundation, the library’s location — at the heart of the complex — is designed as a space to foster cross-disciplinary exchange and collaboration. The gift also provides flexible discretionary funding to the John A. Paulson School of Engineering and Applied Sciences to support early-stage faculty research, graduate students, and investments in computing and laboratory resources, fueling work in areas such as artificial intelligence; climate, energy, and sustainability; and engineering solutions that improve human health.

At the dedication, Garber reflected on Wojcicki’s ties to Harvard and the significance of the Troper Wojcicki Foundation’s gift.

“I can’t imagine a more fitting expression of [Susan’s] connection to the University and her commitment to changing and improving lives and making a difference in the world,” he said.

This gift builds on Wojcicki and her husband, Dennis Troper’s, legacy of philanthropic support across Harvard, which includes seed grant funding for the Salata Institute for Climate and Sustainability, fellowships through the Harvard Data Science Initiative, and graduate fellowships in computer science at SEAS.

He noted that the Troper Wojcicki Foundation’s support will help students and faculty at the complex and across SEAS address some of the greatest challenges facing society today. “We are so deeply grateful to you, Dennis, and to the entire Troper Wojcicki family,” Garber said.

“Here, Susan’s legacy will be visible to future generations of students who will use this space to solve problems, collaborate, and develop the skills they need to become the next generation of leaders in science and technology,” said dean of the Harvard John A. Paulson School of Engineering and Applied Sciences David Parkes. “I want to thank Dennis and the Troper Wojcicki family very much for their transformational support of the work we do and the community we foster here at [SEAS].”

University Librarian Martha Whitehead underscored the importance of this legacy. “The Susan Wojcicki Library, like Susan herself, is a connector,” said Whitehead. “Situated in the middle of the SEAS community, it serves as a doorway into the world’s largest academic library and collections that will spark new ideas and fuel innovation.”

Wojcicki graduated from Harvard College with a concentration in history and literature, but her time at Harvard was marked by a curiosity that extended beyond any single field. She worked in Widener Library as an undergraduate and, as a senior, enrolled in “Introduction to Computer Science” — the only humanities concentrator in the class. Her instinct to cross disciplinary lines would define both her career and her vision for what technology could make possible. At Google and YouTube, she rose to become one of the industry’s most influential leaders, guided by a conviction that great ideas emerge at the intersection of different ways of thinking. She was also known for recognizing the promise of new ideas and creating pathways for opportunity.

Wojcicki remained closely connected to the University throughout her life, serving on the Global Advisory Council, the Committee on University Resources, and the University Task Force on Science and Engineering. Her service reflected a longstanding commitment to bringing people together across areas of expertise and expanding opportunity for the next generation.

In his remarks, Troper shared his reflections on Wojcicki, their life together, and why the library is such a fitting place to bear her name.

“It is so moving that this space is now the Susan Wojcicki Library. May this library be a sanctuary for the bold, a lab for the curious, and serve as a reminder to every student here that no matter what your major is, you have the power to change the world.”

Retired SCOTUS justice says path to less polarization runs through the classroom

Retired Supreme Court Justice Stephen Breyer argued that civic education could help reduce polarization and strengthen citizenship during a forum at the Ed School last month.

“We are in sort of a period where people seem to be arguing quite a lot and disagreeing,” Breyer, who is now Byrne Professor of Administrative Law and Process at Harvard Law School, said in a conversation with Martin West, academic dean and Henry Lee Shattuck Professor of Education, on April 21. “I think in the longer run, the only possible solution is to restore 12th-grade civics.”

Breyer, who served on the court from 1994 to 2022, spoke about his own civic education in San Francisco public schools, which helped spark his interest in public service and taught him the value of civic participation in a democratic government.

“We used to get in a bus and go to Sacramento,” said Breyer. “We’d see the legislature in session, and we’d have ‘Youth in Government Day,’ where everybody took on the position of somebody in San Francisco’s government, so that the kids knew by the time they graduated that they’d better participate in that government — that it’s their government.”

Throughout his career, Breyer has highlighted the role of public education, among other institutions, in strengthening democracy. His books include “Making Our Democracy Work: A Judge’s View.” In 2021, he wrote an 8-1 decision supporting student free speech off-campus, arguing that “America’s public schools are the nurseries of democracy.”

When asked about the role of the Supreme Court in civic education, Breyer said that justices should write in a clear way to ensure that citizens understand both the complexities and the practical impact of a ruling. To underline his point, he recalled a meeting between the Dalai Lama, the exiled spiritual leader of Tibetan Buddhism, and several Supreme Court justices.

“When the Dalai Lama came to the Supreme Court … he asked, ‘What do you do when you have to decide a case that is under the law but immoral?’ We all said, ‘Well, you try to prevent that …’ And if you actually can’t prevent it because it is in the law, you do your best to explain it.”

When asked for advice on how to foster constructive dialogue, Breyer brought up his service as chief counsel of the U.S. Senate Judiciary Committee in the 1970s — specifically the example set by the committee’s chair, Sen. Ted Kennedy.

Kennedy, a Democrat, sought to reach across the aisle, said Breyer, paraphrasing the senator’s message to his staff when it was time to negotiate with Republicans: “Go talk to them, but don’t talk too much. Listen. If you listen long enough, very often, not always, but very often, they will say something that you genuinely agree with.”

Breyer praised the work of several foundations and organizations that are promoting civic education among middle- and high-school students. He noted his own work with the University of Pennsylvania’s Annenberg Classroom, which offers free lessons on the Constitution and the Supreme Court.

He said that he remains optimistic about young people’s efforts to participate in civic life and pursue careers in public service.

“They’re interested in what they might do to cure some of these problems in front of us,” he said. “And it’s the look in their eyes that makes me optimistic.”

The award, through the Harvard & the Legacy of Slavery Initiative, will strengthen research capacity at 15 schools

4 min read

Harvard has announced a three-year, $1.05 million grant to the Association of Historically Black Colleges and Universities Research Institutions (AHRI), a new coalition of 15 HBCUs working to enhance their collective research, innovation, and impact.

The grant, made through Harvard & the Legacy of Slavery (H&LS) Initiative, will support research infrastructure and technical assistance at these schools as they build research capacity and seek to achieve R1 status — the highest research designation offered to United States universities — under the Carnegie Classification of Institutions of Higher Education. Harvard’s Office of the Vice Provost for Research (OVPR) will provide technical support.

“Through this three-year grant to AHRI, the H&LS Initiative is deepening our commitment to developing enduring partnerships with HBCUs,” said Sara Naomi Bleich, vice provost for special projects at Harvard. “We are honored to leverage our expertise in research infrastructure and capacity-building to help further HBCU research excellence.”

The new funding strengthens Harvard’s commitment to building partnerships at HBCUs, while enhancing their ability to attract top research talent and funding that come with R1 research classification. Howard University is the first HBCU to have earned an R1 designation and is currently the only partner institution in AHRI with that designation.

The grant directly implements Recommendation Three from the 2022 Report of the Presidential Committee on Harvard & the Legacy of Slavery, which called on the University to forge lasting connections with HBCUs.

“The launch of AHRI represents an important inflection point for HBCU research institutions. The 15 universities in this coalition collectively account for 50 percent of all competitively awarded federal research funding among HBCUs — underscoring the scale and strength of our research, doctoral education, and innovation,” said Tomikia P. LeGrande, president of Prairie View A&M University and vice chair of AHRI. “As Carnegie-classified institutions spanning R2 and R1 designations, we are aligning that strength through AHRI to amplify impact, accelerate discovery, and define the future of research while firmly establishing HBCUs as central to that future.”

“AHRI marks a new chapter in the HBCU research landscape,” said Ruth Simmons, senior adviser to the president on HBCU engagement at Harvard and president emerita of Smith College, Brown University, and Prairie View A&M University. In 2024, Simmons and Bleich began talking about ways Harvard could support advancing research capacity at HBCUs. “This association brings institutions that have too often worked in isolation into sustained collaboration with one another and with the country’s leading research universities. Harvard’s partnership with AHRI offers a powerful model of a more forward-looking approach to higher education.”

Along with the OVPR, Harvard’s Office for Sponsored Programs (OSP) will provide technical assistance and guidance in designing and strengthening research administration and compliance infrastructure across AHRI member institutions. This will include participating in the inaugural AHRI symposium, hosting HBCU administrative staff at Harvard, and assistance with lifecycle grants administration and compliance.

AHRI formally launched April 29, at Howard University in Washington, D.C., with a national press conference and inaugural symposium, “Expanding the Research Mission of HBCUs.”

Beyond the new AHRI grant, the H&LS Initiative also supports the next generation of HBCU leaders through Harvard’s Seminar for New Presidents leadership program, which provides a collaborative cohort learning model for HBCU and non-HBCU presidents. Additionally, the H&LS Initiative supports capacity building through the HBCU Digital Library Trust, which has engaged more than 90 HBCUs in digitizing high-priority collections on a single platform and providing professional development programs. The initiative also funds research opportunities like the Du Bois Scholars Program, a summer research internship at Harvard University for undergraduate students from 21 research-intensive HBCUs.

‘Harvard Thinking’: Why we love dogs — and they love us back

long read

In podcast, experts break down evolution and biology of this special relationship

Nearly half of all American households include a dog, according to Pew Research. That same survey found that most pet owners, especially dog owners, consider their pets to be part of the family. How did dogs go from being wild animals to our best friends?

“Scientists think that dogs probably domesticated themselves. Nobody really knows for sure, but the current thinking is that there were probably wolves that were hanging around human settlements tens of thousands of years ago, and the wolves that were less afraid of humans and could make humans less afraid of them were able to obtain survival benefits,” said Erin Hecht, director of The Canine Brains Project in the Department of Human Evolutionary Biology.

In this episode of “Harvard Thinking,” host Samantha Laine Perfas explores the special relationship between humans and dogs. In addition to Hecht, she is joined by Alice Hoffman, author of “The Best Dog in the World: Essays on Love,” and Elizabeth Frates, an associate professor at the T.H. Chan School of Public Health and Harvard Medical School, who explains how some dogs even act as “lifestyle coaches” for their owners.

Erin Hecht: There’s sort of a tongue-in-cheek idea that dogs are psychological parasites, that they’ve evolved to hack our psychology and worm their way into our emotions and take over the types of psychological urges that we would normally invest in a human social partner. So I think, they maybe trick us, in a way, into thinking of them almost like little people.

Laine Perfas: Most U.S. families are pet owners, with just under half the population owning a dog, and in the vast majority of the cases, the owner thinks of the animal as a member of the family. The love goes both ways. Dogs depend on us for their survival, just as humans benefit from their presence. Research shows that having a furry companion is good for us physically, emotionally, some might even say spiritually. Why is that?

Welcome to “Harvard Thinking,” a podcast where the life of the mind meets everyday life. Today I’m joined by:

Alice Hoffman: Alice Hoffman. I am a novelist and also an alum from the Divinity School.

Laine Perfas: She’s published dozens of works of fiction, including the bestselling “Practical Magic” series. She most recently edited the nonfiction anthology, “The Best Dog in the World: Essays on Love,” which features the stories of various authors and their dogs. Then:

Elizabeth Frates: Dr. Beth Frates. I am an associate professor, part-time, at Harvard Medical School and the immediate past president of the American College of Lifestyle Medicine.

Laine Perfas: She spearheaded the Harvard Medical School special health report, “Get Healthy, Get a Dog.” And finally:

Hecht: Erin Hecht. I’m an associate professor at Harvard University.

Laine Perfas: She directs the Canine Brains Project, which seeks to better understand why canine minds and brains work the way they do.

And I’m your host, Samantha Laine Perfas. I’m a writer for The Harvard Gazette. Today we’ll look at the science of dogs and why having a furry companion can be so beneficial to our wellbeing.

 How did dogs go from being wild animals to our best friends?

Hecht: Scientists think that dogs probably domesticated themselves. Nobody really knows for sure, but the current thinking is that there were probably wolves that were hanging around human settlements tens of thousands of years ago, and the wolves that were less afraid of humans and could make humans less afraid of them were able to obtain survival benefits in the form of scrapped food and maybe shelter. So then, gradually over time, we had this population of wolves that gradually turned themselves into dogs and were living around people. And that’s actually how most of the dogs on the planet live now: not inside human households as pets, but just around. They’re called village dogs.

“There’s sort of a tongue-in-cheek idea that dogs are psychological parasites, that they’ve evolved to hack our psychology and worm their way into our emotions … and maybe trick us in a way into thinking of them almost like little people.”

Hoffman: It’s interesting because I have a new dog and she’s a Tibetan terrier. And when I finally did research to try to understand why, I’ll be walking her, and she’ll leap into some strange man’s arms, that they were village dogs. They were raised as village dogs. They weren’t connected to one person, but to the entire village. That’s who she is. I’m not used to that, but in my further research, I found that they also make very good support dogs and therapy dogs because they’re so friendly and because they don’t have stranger fear; she never barks when someone comes to the door. She’s really a village dog, but I don’t have a village, really. So I think I’m going to change my life to suit my dog.

Frates: I find that so fascinating, Alice, because what we find in the research around lifestyle behaviors and pet owners or dog owners is that the human in the relationship prioritizes the dog. For example, I must go out and exercise my dog. Now we know that humans need 150 minutes of moderate-intensity physical activity each week, and humans are much more motivated to do such when the human believes the furry friend needs this. And even in terms of when a human is thinking about nutrition, many people are thinking about the preservatives in their dog’s food and the quality of the dog food as well as thinking about their food. Their behaviors around food and what they believe to be healthy, they want to do for their dog.

Laine Perfas: You could make the argument that initially, dogs benefited the most from being around humans. But as we have seen, it’s this true symbiotic relationship. So I wanted to talk a little bit about the ways that we see the benefits for dogs. And then what is it for humans that we are also benefiting from this relationship?

Hecht: I could talk about the benefits for dogs. They are truly adapted to live in the human world. They cannot exist out in the wild without us. I guess maybe an exception is dingoes: They have adapted to live out in the wild, but they really are an exception. Dogs have to live with people. They have to live in a human environment, and they need us as social partners. We are their primary social partners. They bond to people. They treat humans like conspecifics, like members of their family. And research has shown that when dogs and humans interact, both members of that pair release oxytocin in their brains, which is a hormone that’s involved in social bonding. It potentiates the action of dopamine in your brain, which is a feel-good reward hormone. And it also inhibits stress chemicals in your brain. So it makes you feel good, and it also helps you not feel bad. So if a dog has a bond with a person, just the presence of that person can help buffer negative experiences for the dog. And the reverse is true also for the person. The presence of that dog can help buffer negative experiences for the person. And that effect is so real that dogs can actually function as health aides for people who have PTSD or anxiety disorders.

Hoffman: I feel like in my life, in my personal life, that I was always closest to the dog. That was my primary relationship. I grew up in a very dysfunctional family. I felt like I didn’t have a family: I had the dog. And it’s always been like that for me, that my main relationship has been with the dog, probably why I’m divorced, but anyway, that’s another story. But now that I have this other dog, that we are not each other’s primaries, I’ve felt more stress than I have a freedom from anxiety. And I realize, as Beth was saying, “I have to change my life to suit this dog.” And in a way, it maybe is what I need because it’s opening my life to other people. I feel like maybe it’s meant to be that it’s not just me and a dog sitting in a room together crying, that maybe this dog is leading me to other places.

Frates: I found my first dog, who was a goldendoodle named Reese. I got her with my family when my kids were young. I was afraid of dogs. When I was a child, a neighborhood Doberman was with us at a skate park. I was with the dog’s owner child, and we were skateboarding tandem together, and we were a little bit out of control and going a little crazy. Probably going to crash. And the Doberman grabbed me with its teeth on the shoulder. I viewed this, as a child, as the dog biting me and was petrified of dogs thereafter. Now, being a dog person, I see this whole scenario and I say, “Oh, the Doberman was trying to save me and its owner from potential disaster.” My husband loves dogs, is a dog whisperer, and finally convinced me to agree to getting this dog Reese, the goldendoodle. And what I want to share in terms of personality and a dog helping us was that at the time I was the mom of two young boys, was working. I also had older parents. There was a lot going on, and I wasn’t very social, even though I love people. I love people. I love my friends, but I was really hunkering down and just getting by, just doing what I needed to do for cooking, cleaning, parenting, work. And then I got Reese and, just as I said earlier, she needs to go out for a walk. So I would go out for a walk in the neighborhood. Suddenly I had 20 new friends. I was suddenly invited to dinner parties and dog play dates and events that the ladies in the neighborhood were having. I made so many new friends and became so much more social because of Reese.

“When I think about a dog now, I think about them as a lifestyle medicine coach because one of our pillars is physical activity. Another pillar is stress reduction. And then we have the pillar of social connection.”

Laine Perfas: One thing, Beth, you mentioned in your response was the personality of dogs. Are there dogs or dog breeds that are more naturally friendly, more intuitive, or more aggressive? How do their genetics versus their environment affect how they behave around us?

Hecht: This is something that scientists have been really interested in for a long time, and it’s been a difficult thing to study because it’s tricky to separate the genetics from the environment, because those things tend to not be randomly distributed. Certain types of people end up liking certain types of dogs. If you’re a really athletic person, you might like a dog that’s super athletic, and certain types of breeds are more athletic. And then you wind up with dogs that have personality traits that kind of go along with an active lifestyle. But all that is to say, there are breed differences in behavior and personality. You can trace them to variants in the genome that we know are related to similar aspects of personality in humans. But breed doesn’t determine everything. Genes don’t determine everything. You might think of it as a breed sets a range where personality might fall into for a particular dog, and then the dog’s environment and upbringing and a little bit of random chance kind of sets where that particular dog is going to land within that range.

Frates: I also think this is good to know for anyone who’s listening to this and thinking, I really need to get a dog for my health. I think it was 2016, soon after I got my first dog, my colleagues tapped me for this Harvard special health report on “Get Healthy, Get a Dog.” I dove into all this literature on how the dog does in fact help us as the human to attain the physical activity guidelines, which I mentioned. And then there’s now guidelines on nature, recommendations to get out in nature for 120 minutes per week. The dog absolutely helps us with that. When I think about a dog now, I think about them as a lifestyle medicine coach because one of our pillars is physical activity. Another pillar is stress reduction. And then we have the pillar of social connection, which we’ve talked about a little bit in terms of feeling connected, as Alice was saying to the dog itself. And then I mentioned how my dog Reese helped me socially connect outside my own home. So this dog can help us in many of our lifestyle behaviors, and also is a real mindfulness instructor. The dog is just living in this moment. Happy to be outside. Smelling everything in the present, right now, right here. Really living with its five senses.

Laine Perfas: Who should not get a dog?

Frates: Dogs come with a lot of responsibility. They take a lot of time to love. You need to love that dog and treat that dog like a real member of your family. You really do need to have time. And not everyone can afford a dog. There are vet appointments, there’s food, there’s time out of work that you need to spend with the dog. I love dogs and I do believe they’re great for our health. And again, there’s data that shows people who own dogs tend to have lower blood pressures, tend to also have lower cholesterol levels, even. This is likely all due to the movement that they’re encouraged to get and the stress resiliency. Yes, dogs are wonderful for health, but we also have to think about what responsibilities come with that dog. And perhaps piggybacking on the breed, and also researching the breed, and does that breed match your lifestyle.

Laine Perfas: I wanted to pick up on something you said about how important it is to treat dogs as if they’re a member of our family. I think sometimes with animals, we assign a lot of human characteristics to them. We want them to be like us. What do we know about their actual emotional depth and capabilities compared to humans?

Hecht: So first of all, I think dogs absolutely have emotions. They have an inner life. They experience the world, they have an awareness. But I think we shouldn’t assume that their emotions are identical to ours or that they experience the world the same way that we do. And some emotions that we experience might have a little bit of cognitive complexity that doesn’t exactly map onto what dogs experience. One example might be jealousy. I think, when humans experience jealousy, we have some sort of complex understanding of somebody having something that we don’t have and what it would be like if we had it and why it’s not fair that we don’t have it. There are a lot of layers going on there. If you have a dog, you’ve probably had an experience where it feels like your dog is jealous, either of another dog getting something that your dog’s not getting, or you’re giving attention to another dog and your dog starts to get upset or something like that. So it starts to seem like your dog is jealous. I would guess that your dog is experiencing something like jealousy, but their internal awareness probably doesn’t have all of the layers of complexity that we have. But things like love and fear and happiness and joy, curiosity, playfulness, I think they have all of that.

Hoffman: I have a book that’s an anthology, and 14 fantastic writers like Amy Tan and Isabel Allende and Roxane Gay all wrote about their own experiences with dogs. It was so interesting to hear about other people’s most intimate relationships with their dogs. And I felt like most of these people, I knew. I knew their writing and I knew them. But I got to know them in a different way when they wrote about their dogs because it was a certain kind of intimacy and depth that I had never seen before. And it was just a different way of knowing them to know how they felt, what their relationship was with their dog. I think you’re so right in that we assume that they’re feeling certain things that we are feeling, but it’s pretty hard not to assume that when you’re so close to them; you’re living in such an intimate space with this other creature.

Hecht: Our minds are built to understand human minds really on a fundamental level. And I think dogs have probably evolved to tap into that. There’s sort of a tongue-in-cheek idea that dogs are psychological parasites, that they’ve evolved to hack our psychology and worm their way into our emotions and take over the types of psychological urges that we would normally invest in a human social partner. So I think they maybe trick us in a way into thinking of them almost like little people. And that probably helps them integrate into human families. But I wonder if, in some ways, it could also hurt them. If we don’t also keep in mind that they’re not humans and they have some different needs than humans do that we also have to account for.

Hoffman: Yeah, my current dog does not feel like a human. And I think that’s part of the reason I have a little bit of trouble relating with her. And she’ll do things like sit in a darkened corner staring, and I’m thinking like, “What is she seeing that I’m not seeing?” We’re like in two different worlds. I do feel that with her.

Laine Perfas: Alice, are there any essays from your book that stood out to you regarding people’s different relationships with their dogs?

Hoffman: One that I love is by Roxane Gay, and she said she didn’t grow up with dogs. Haitian families don’t usually have dogs. They’re like village dogs in Haiti. And her wife wanted to get this dog and was a dog person, and they got this dog, and Roxane felt that the dog didn’t like her. And she was then very upset and depressed that the dog didn’t like her. By the end of the essay, she is that dog’s person. And things just completely changed. But there were several things. Jodi Picoult also has an essay about a dog that really didn’t like anybody, and she had several dogs. So it was like, it was interesting to see how it’s not all the same, where you just get this dog and you just love each other, that these relationships are all so different.

Frates: In our family, it seemed that our dog, Reese — by the way, she lived a beautiful life of 12 years, and now we have Athena, who is a German shepherd, a very different dog. But using the example of Reese, the goldendoodle, when the boys were younger, and for me as an adult, middle-aged woman, it seemed that with Reese, she was the unconditional love that everybody wants and needs at times. And I know, as a lifestyle medicine expert, physician, coach, listening is key to any relationship. I believe that Reese had this capacity to sit at attention and listen to me, to my kids, almost like a little lifestyle coach, and almost respond with empathy, it seemed to me. Reese could behave in a way that led us all to feel she loved us so much and understood us and would even lick you right when you were sensitive or if you were crying. She would come to you, actually reach for you and sit by you, maybe even sit on your foot when you were upset, near crying, not even yet having tears.

Laine Perfas: I grew up with dogs. I am currently a cat owner, but growing up with dogs, I’ve got to say it was only when one of our dogs died that I ever saw my dad cry. My brother, very stoic, but will weep at movies where the dog dies to the point where he won’t even watch them anymore. Dogs have this capacity to bring our emotions to the surface in a way that seems special.

“When we get a dog, we know, unless we’re a certain age, you know that you’re going to probably outlive your dog, and there’s something just tragic from the beginning about that.”

Hoffman: I think part of it is that they don’t live long enough, and so there’s always something kind of tragic about that. There’s one essay in the book that I did by Emily Henry, who’s a wonderful writer, and she starts her essay with, “The dog dies in this. Before we go any further, you should know that.” When we get a dog, we know, unless we’re a certain age, you know that you’re going to probably outlive your dog, and there’s something just tragic from the beginning about that.

Frates: I think losing a dog is really a challenge for many people. It certainly was for me. It was my first dog. So I’m an adult woman, and I didn’t understand the depth of the grief, losing a dog. And I will say that I was thinking, I don’t think I can do this again. That’s important for people to understand when they want to get a dog, and get a dog with a family that has children — because my children, it was also hard for them. But I wouldn’t change it. I wouldn’t not get Reese, no.

Hoffman: I know that when my dog passed away, Shelby, which was about a year ago, and we were extremely close, we were together every moment. She was my soul sister and very special to me. And afterwards, I joined a grief group, and people were so deeply in grief that oh, I couldn’t bear it. Also what was interesting, none of them had replaced the animal that they had lost. And I rushed to replace, which was a mistake. I now realize why these people hadn’t: They needed a long time to grieve, and I think sometimes people, and myself included, don’t really understand how long it takes to get over something like this. So I left the group that night, but I wish I had stayed. I think I was too afraid of their grief.

Hecht: Alice, I think you hit on something I wasn’t quite sure how to put into words. I wonder if there’s this layer to human relationships that is complicated. It involves language and rationalizations and all this complexity — and with dogs, it’s just really simple and emotional and raw. And maybe that’s why losing a dog is really hard. And why dogs can just get right to your emotions in a way that sometimes people can’t.

Laine Perfas: People are complicated, like you said, Erin, and I wonder if there is something about dogs that does provide that space that is a little bit more accessible to people. We’ve learned so much about dogs and the ways that they have affected and changed us. What are we still hoping to learn about dogs, both dogs themselves, but also the relationship they have with humans?

Hecht: For me, one of the things that I hope that we’ll learn that our lab is working on right now is how to help dogs that have experienced trauma. Dogs that have experienced stressful events early in their life, just like people, often have lingering challenges, emotional and social challenges, for years to come. People who have dogs that have these kinds of challenges often struggle a lot to try to deal with things like separation anxiety or reactivity or tearing up the couch when the person leaves the house, that type of stuff. We have some treatments, but they’re not great. We have seen from some research in our lab that it seems like different breeds of dogs have different levels of sensitivity to early life stress. Some breeds seem to have pretty low sensitivity to early life stress. So lucky them, they can go through difficult things and be resilient and bounce back. And other breeds seem to have pretty high sensitivity, so they’re more likely to be more impacted. What this tells us is that there’s probably some genetic underpinning, some genes that we could identify that are either conferring resilience or sensitivity. If we could identify those genes and the biological pathways that they’re involved in, that might lead us to treatments. So that’s something that we’re working on now, and we’re actually enrolling dogs that have experienced early life stress and that have behavior challenges as a result. So if there’s anybody out there that has this type of dog that’s within driving distance of Harvard, we’d love to study them.

people with their dogs

Frates: I think on the medical side, perhaps people have heard that dogs can sense diabetes and can be helpful for patients who have diabetes in detection of their hypoglycemic episodes. I think that better understanding how a dog could help a human manage, even, seizures. Some dogs can help with seizure management. I’ve seen studies with migraines and narcolepsy. So how can the dog use its special capabilities to help the human manage some chronic conditions that can be really debilitating? That research is ongoing, and it’s powerful. It lets the dogs do a tremendous job to help their own humans. Now, I’m giving some sort of human qualities to the dog, but I feel that the dog would feel value and also feel perhaps pride and be happy to be able to help in this way, because surely they know when their owner is suffering.

Hecht: Yeah, that’s really interesting that you mentioned that. Our lab is actually also studying these service dogs and medical detection dogs. I absolutely agree with what you say. I think that this bond between the dog and their handler is really crucial, and I think that most handlers would agree that their dog cares about them and wants to help them when they’re in trouble. A surprising thing that many people don’t know is that about half of the dogs that go through training to have these types of really specialized working roles, they don’t make it through training. It’s a really high bar to pass to have these really challenging working roles. The organizations that are breeding and training these dogs, they’re really struggling because they’re providing these dogs for the people that need them at either low cost or often no cost. They’re struggling to provide the number of dogs that are needed, with a large number of dogs washing out. As a result, there are often multi-year waiting lists to get a dog of this type. So one of the things we’re working on in our lab is to try to figure out what’s going on in the brains of the dogs that are doing a good job, and can we use that information to help these organizations produce more dogs more quickly and more efficiently?

Laine Perfas: Does anyone have any advice for someone who doesn’t have a dog but is thinking about getting a dog?

Hecht: You could foster a dog, or you could go to your local humane society and volunteer to walk dogs and see how you like that. Get a little practice run before you commit fully, so that way you can make sure that it’s really something you want to do before you take it on.

Frates: I like that idea. Maybe dog-sitting for someone who has a dog, living a little bit with a dog could be helpful. Even going to a park, a dog park with a dog owner. Because I found that very overwhelming as the dog owner that was afraid of dogs and is new to dogs and came to the dog park with all the dogs jumping and everything happening. Having some experience with those dog-owner activities may be fun and also helpful. Reading a book about dogs, what it takes to care for a dog, what a responsibility it truly is, and are you ready for that emotionally, financially, family-wise. Also just doing a little bit of research on breeds, or if you want to go for a shelter, I would say researching how to be the best dog parent of a dog who’s come from a shelter whose background you don’t know, maybe preparing for that.

Hoffman: I agree so much with Erin and Beth. I think, like a lot of things, part of it is luck. It’s like falling in love, and you just never know what’s going to happen. You’re just going to have to wish for the best. It takes a lot out of you. It’s a huge commitment. Sometimes it works out, sometimes it doesn’t. But you’re in it. And so I think it makes you work harder to have a really great relationship that is going to be maybe one of the most important relationships in your life.

Laine Perfas: Thank you all for this really great conversation.

Hecht: Thank you very much.

Frates: Thank you.

Hoffman: Thanks.

Call for ‘historical truth’ in our narrative of Nazi defeat

Call for ‘historical truth’ in our narrative of Nazi defeat  

Jochen Hellbeck wants the West to acknowledge the Soviet role in stopping Hitler

6 min read

On this side of the Atlantic, World War II can appear in the popular imagination as a contest between liberal democracies and totalitarian empires.

That narrative, shaped largely by Cold War enmity between Washington and Moscow, tends to overlook the unimaginable sacrifices of the Soviet Union and its people, roughly one in seven of whom died in the conflict. 

So, though it covered familiar names and dates, Jochen Hellbeck’s lecture on campus last Thursday carried an unusual charge.

Hellbeck, a German-born historian who now teaches at Rutgers University, has spent his career using archives to relocate the center of the European war to points well east of Normandy — specifically, to the collision between Nazi Germany and the Soviet Union.

By the numbers, that shouldn’t be controversial. As they invaded the U.S.S.R. in the summer of 1941, Germany and its European Axis allies opened the bloodiest theater of war in human history. 

All told, the Soviets counted roughly 26 million dead — more than half of them civilians lost to starvation, siege, and several years of clockwork atrocities. Three out of four of the Third Reich’s own 5.3 million military fatalities came in the East. And the defeat at Stalingrad in February 1943 marked a turning point in the German war strategy.

Hellbeck’s latest book, “World Enemy No. 1,” goes further, arguing for the central role of anti-Soviet sentiment in what he called the “Nazi designs for mass extermination.” 

To be clear, Hellbeck doesn’t dispute the Nazis’ virulent anti-Semitism. But he notes that from Hitler’s earliest days as a political figure, that hostility was often intermingled with a violent hatred of the Soviets, captured most succinctly in the party’s stock phrase: “Judeo-Bolshevism.”

“World Enemy No. 1” has proven controversial, Hellbeck acknowledged — most of all in his native land.

When an early edition of the book appeared in German, the reception was icy. Hellbeck recalls being told that “the established history of the Holocaust, as Germans understand it, must not be overturned.” 

He is of two minds about that reaction. As a historian, “There’s always excitement, to see that you touched a nerve,” he said. “But then not to have a chance to discuss it, in those rooms, is disappointing.”

In any case, his revision aims not to overturn a narrative, he said, but to widen the frame around that war’s infernal final years.

“Traditionally, we have understood the Holocaust as derived purely from anti-Semitic venom — and of course, that was a very central element,” Hellbeck told his audience at the Center for Middle Eastern Studies.  

“I’m just adding a political dimension to that — that is, the Nazis’ anti-Communism — and arguing that the drive to exterminate came during the conflict with a Communist enemy who was coded as Jewish.”

Hellbeck came to Harvard to deliver the 11th annual lecture in memory of Hilda B. Silverman (Radcliffe ’60), a longtime peace activist and University affiliate, who died in 2008.

The lectures touch on issues that were near to Silverman’s heart, including the Holocaust and the ways it still shapes our politics and culture.

Sara Roy, CMES affiliate and chair of the lecture committee, said that Hellbeck clearly fits the mold. By giving voice to the human beings who lived under Stalin and helped defeat Hitler, he has “contributed greatly to a more capacious and humane understanding,” even of geopolitical adversaries.

Hellbeck spent much of his lecture resurfacing the Nazi regime’s enduring obsession with defeating Communism.

As early as 1921, Hitler, still a regional figure, alleged that “400 Soviet commissars of Jewish nationality” lived well while millions of citizens suffered in poverty.

Once the Nazis took power 12 years later, German citizens were treated to a battery of anti-Soviet propaganda and traveling shows, including the 1936 exhibition that gave Hellbeck’s book its title. 

With lurid posters and slogans, “They taught Germans that Bolshevism was evil and bestial … that it was the work of Jews who are the most monstrous and menacing in their Soviet Communist incarnation,” Hellbeck told his audience. “And these shows drew millions of German spectators, including young boys who would later fight as soldiers at the Eastern Front.”

It was on that front that Nazi mass extermination began in earnest. Before death camps came the “Holocaust by bullets,” mass shootings committed by so-called Einsatzgruppen in the occupied territories of the U.S.S.R. 

That campaign’s targets were described in one context as “politically and racially unacceptable elements.” It would leave millions of Jews, but also Communist party officials and Soviet intellectuals, dead in mass graves across Eastern Europe.

Images and stories — some factual, some exaggerated — of Soviet brutality were circulated in the Nazi press. And Hellbeck argues that acts of resistance by European Communists during Nazi occupation allowed the German regime to win consent for its mass killing: by redefining Jews not just as racial “others,” but as “Stalin’s auxiliaries” — enemies within.

While it might not be surprising that Nazi anti-Bolshevism was downplayed while Western countries were embarking on their own long anti-Soviet struggle, Hellbeck noted that his work is aimed at a historical “lacuna” that has endured to the present day.

“In 2019, the European Union passed a resolution … to essentially indict Nazi Germany and the Soviet Union as equivalent totalitarian powers,” he said.

He argued that that measure dishonors the memory of millions of Russians, Ukrainians, and Belarusians who, during Nazi occupation, came to see even the brutal Stalin regime as the lesser of two evils.

That made even this provocative book worth writing, Hellbeck said. 

He closed his lecture with “a plea for an honest reckoning with the past.” His argument for may “run up against the desire of Western leaders to portray their countries as the leading victors … [or] appears to play into the hands of the Russian president, who invokes the Soviet contribution to victory over Nazism as a justification for his current war against Ukraine.”

“That the Soviet Union played such a central role in the Nazis’ deadly designs is an inconvenient truth in today’s world,” Hellbeck said. “But historical truth is not subject to negotiation, and historians must not yield to the political pressures of the present day. Only then can the writing of history become a basis of meaningful discussion and dialogue in tomorrow’s world.”

Mount Everest

Experienced mountaineer, researcher fell short of summiting, but his work has helped make climbers safer

Climbing Mount Everest is getting safer, a new study shows, though the world’s highest peak remains dangerous enough that almost one in 100 who try it don’t make it home.

The work, led by Paul Firth, an experienced mountaineer and associate professor of anesthesia at Harvard Medical School and Massachusetts General Hospital, builds upon his earlier research into high-altitude deaths on the mountain since the first recorded summit attempt, George Mallory’s expedition of 1921.

Firth and colleagues want to better understand what happens to the human body at high elevations to guide efforts to make climbing safer. That initial research, published in 2009, found that cerebral edema likely played a role in many more high-altitude deaths than was previously understood.

The condition develops in regions of low oxygen like Everest’s “death zone” above 26,200 feet, or five miles up. Fluid leaks into the brain, causing headaches, extreme fatigue, coordination problems, and impaired judgment, any one of which presents a hazard in conditions where a single mistake can cost your life.

“Contrary to perceptions and media reports, things are actually safer now, but still very dangerous,” Firth said.

“Contrary to perceptions and media reports, things are actually safer now, but still very dangerous.”

The current research, published in The Journal of Physiology in late April, showed that death rates during climbing expeditions fell by half between the initial period — 1921 to 2006 — and more recent years, 2007 to 2024, with the mortality rate falling from 1.4 percent to 0.7 percent.

Firth and colleagues credited a number of changes in recent years with lowering the death rate.

Most attempts today occur along known, standard routes, which feature fixed ropes. In addition, weather forecasting has improved greatly, as have communication systems, allowing much freer flow of information about what awaits higher up on the mountain.

And advances in logistics, clothing, nutrition, hydration, and oxygen delivery systems have each lowered the risk to climbers from cold, hunger, thirst, and thin air.

“The data are that fewer people are involved in falls, and fewer people are getting isolated, left behind, and dying alone,” Firth said. “We speculate that teamwork has improved and that everything being roped the whole way has helped markedly, but there are many other things that could have contributed which we weren’t able to measure.”

Climbing Everest has always been a life-threatening endeavor.

The first recorded summit was by Tenzing Norgay and Edmund Hillary in 1953. Other parties had not been so successful.

Two died on the first expedition in 1921, though their deaths were en route to the mountain. An avalanche claimed the lives of seven porters on the second expedition in 1922.

Four died in the third attempt, in 1924, including George Mallory and Andrew Irvine, who disappeared on the first known attempt to reach the summit and whose remains were only found in recent decades.

A total of 426 have died in Everest expeditions as of 2024.

According to the current work, a portion of which was funded by the MGH Anesthesia Department, just over half of the deaths occurred in the “death zone.” The air at the summit holds just a third of the oxygen at sea level.

Firth said that most deaths now occur on good-weather days due to lack of oxygen and the extreme cold at that altitude. Improved forecasting has reduced losses directly related to bad weather.

The new work highlights the increased popularity of climbing in recent decades, with 1,921 summits through the 85 years up to 2006, and 9,823 summits in the 18 years since.

Though the mortality rate has fallen, climbers still die almost yearly on the mountain, and many years have seen multiple lives lost.

One such year was 2004, when seven people died on Everest, several during a day when Firth himself was leading a small expedition to the top.

Luckily, Firth’s interest in the physiological effects of high-altitude climbing had primed him to recognize warning signs after his oxygen equipment malfunctioned. He started to fall behind, so he called a halt and brought the group together.

He sent one climber up with adequate oxygen while Firth and the others continued down.

There were no deaths among his team and the climber sent on the second push made it to the top without incident — the first Norwegian woman to summit Everest.

The study highlighted disparities between deaths of climbers and the native sherpas who provide professional porter and guide services.

Three-quarters of deaths among climbers occur high on the mountain, on “summit day” — the last push to the top — or on the way down. The vast majority of sherpa deaths, by contrast, happen lower on the mountain, as they prepare the route for their clients.

Firth was disappointed at not having summited, but he has no doubt now that turning around was the right decision, one reinforced by the deaths on the mountain that day and by his research since.

He’s also content that his two studies of Everest deaths have contributed significantly to the climbing community.

“To me, actually doing the study gave me more of a sense of achievement than climbing Everest,” Firth said. “This was my, ‘Hey, I didn’t climb Everest, but I did the study instead.’ It’s my personal Everest in research.”

Presidential dreams can wait. For now, she can’t stop painting.

4 min read

When Daniela Solis took an art class junior year, ‘it felt like time stopped.’

A collection of features and graduate profiles covering Harvard’s 375th Commencement.

Inspired by the trailblazing female politicians of her native Costa Rica, which elected its second woman president earlier this year, Daniela Solis ’26 arrived at Harvard with a dream to run for office.

“I’ve always wanted to become president since I was a little kid,” said Solis. “I always wanted to study government to serve my country better.”

Then an arts class in her junior year opened her eyes to an entirely new calling she never would have predicted.

“What I experienced doing art was something I had never experienced before,” Solis said. “When I was painting, it felt like time stopped. Nothing else exists.”

The government concentrator with a secondary in Theater, Dance & Media said that after graduation she plans to pursue a master’s degree in fine arts. Politics is still on her horizon, she said, but studying the arts has made her a more well-rounded person better equipped to lead others.

“I have been able to find myself through art,” said Solis. “I had never expected that I would become an artist. I have learned that every day gives you the opportunity to change and be a better version of yourself.”

“I have been able to find myself through art.”

Daniela Solis

Karthik Pandian, associate professor in the Department of Art, Film, and Visual Studies, taught the class that made Solis fall in love with art. He said Soltis stood out from the beginning for her “openness” to the “process-driven ways of making art” and her “commitment” to creativity.

Many students, Pandian said, approach assignments with an eye toward the professor’s goals to get a good grade. But in his class, he said, assignments are open-ended, and students are encouraged to be open to serendipity, which can be frustrating to some.

“With Daniela, I got the sense that she was seeking a space like this throughout her studies at Harvard,” said Pandian, “and when she found it in the studio in the Carpenter Center, she leapt through the portal, so to speak, into her own very deep well of creativity and embraced the unknown. She constantly surprised me throughout the semester.”

Since taking Pandian’s class — in which students use materials such as cardboard, charcoal, and found objects to create art — Solis has produced more than 40 pieces. She sometimes spends five hours a day working on art projects. This past winter, she painted a mural in her high school in Costa Rica’s capital, San Jose. On her website Her Reset, which displays some of her work, she writes that “art [is] a way of expanding consciousness and returning to what is most authentic within us.”

Solis’ ability to embrace a path she hadn’t foreseen when she first arrived at Harvard can be traced back to the example set by her mother. “She inspired me to be myself, and to care for others. I learned that even when no one is looking at you, you should always choose to do what’s right.”

A single parent, Solis’ mother worked as a real estate agent to provide for her daughter and secure her a good education at a small private high school in San Jose, while also getting involved in local politics. Influenced by her mother, but also by her country’s female politicians, Solis dreamed of running for office. A country of 5.2 million people, Costa Rica has had two female presidents: Laura Chinchilla in 2010, and Laura Fernández Delgado, who was elected in February. At present, female lawmakers represent the majority in Costa Rica’s legislative assembly.

For Pandian, Solis’ felicitous encounter with art is an example for all students. Many professors lament that students spend their undergraduate years preparing for a career path and a high-paying job after graduation, instead of exploring the humanities, the arts, and social sciences.

“There are many ways that you can make an impact in this world, not just through the most clear and visible forms of power,” said Pandian. “Through art, culture and transformation of consciousness, we can do great things as well.”

Historic collab: Harvard’s Glee Club, Fisk’s Jubilee Singers

Two of nation’s most storied collegiate choirs join to share, perform in Nashville

4 min read

Both are among America’s most storied collegiate choral groups.

Harvard Glee Club, the nation’s oldest (1858), helped establish the university choir as a fixture at U.S. institutions of higher education. The Fisk Jubilee Singers (1871) have garnered national and global fame over the decades, pioneering choral versions of African American spirituals, preserving and presenting the unique tradition to new audiences.

Members of the Harvard group say it once had been club lore that theirs was the nation’s first collegiate choir to tour internationally. That is until they discovered Fisk, which first toured Europe in 1873 (and performed for Queen Victoria), had beaten them by about 50 years.

Oddly enough, until this past spring break, the two groups had never shared a stage over the past 155 years.

“These are two of the oldest choirs in the United States, and two choirs that, I think it’s safe to say, have a bit of historical significance, but they’ve never performed together,” said Andrew Clark, director of choral activities and senior lecturer on music at Harvard. “This has always seemed like an omission, or an opportunity that was worth exploring.”

The Harvard Glee Club and The Fisk Jubilee Singers preforming Due Glory by Braxton Shelley.

The performance highlighted a two-day gathering of the groups on Fisk University’s campus in Nashville, as part of the Glee Club’s March 13-21 tour across the American South.

G. Preston Wilson Jr., assistant professor of music at Fisk and director of the Jubilee Singers, emphasized the importance of having two days for the groups to work with one another — especially given the Singers’ typically hectic touring schedule.

“It’s usually concert, concert, rehearsal, concert, and we don’t get to exist as musicians together,” said Wilson ahead of the collaboration. “But we’re going to have time for the students to just engage and eat and have conversation. … That’s what makes our performances meaningful. We can sing notes on the page all day long, but what are we doing after that?”

The visit included a “choral share,” when both ensembles got a chance to work under the other ensemble’s conductor.

Preston McNulty Socha, a College sophomore and this year’s tour manager, said he and other members of the club were inspired by the cohesiveness of the Jubilee Singers, who often perform without a conductor or musical accompaniment.

“They all look around, and they’re so deeply connected to each other,” he said. “Almost every person is both a soloist, a conductor, and a member of the team at the same time.”

“They all look around, and they’re so deeply connected to each other.”

He called their rehearsals together a mindset shift. While he said he came in thinking of ensemble singing as slotting into a preformed puzzle, it was different with the Fisk singers.

“It was very much — this is my piece; I’ve embodied this piece. This piece is now a part of me,” he said. “And I have this active ownership and potential to really steward and find the direction or inform where the piece is going.”

At the standing-room-only concert at Spero Dei Church in Nashville, the groups performed individual programs and two numbers together: “Witness,” a spiritual arranged by Jack Halloran, and “Due Glory,” composed by Braxton Shelley, a Yale professor.

Shelley, who formerly taught at Harvard and is a minister and performer, joined the chorus during the performance — with his close friend Wilson soloing.

Wilson, a former member of the Jubilee Singers, said he was excited about the Glee Club collaboration.

“I just want to make sure the people know who the Jubilee Singers are in perpetuity — not just because you read about it in a book,” he said. “Come to our concert, visit our campus, take a tour of our campus, and learn about just how wonderful Fisk is and the Jubilee Singers are. Doing this collaboration with Harvard helps that cause.”

The performance is one of several collaborations between the Glee Club and prominent HBCUs over the past few years. These include a 2022 festival weekend collaboration with The Aeolians of Oakwood University, who performed with the Glee Club and The Kuumba Singers of Harvard College in Sanders Theatre.

It’s Clark’s hope that the Jubilee Singers can soon spend a week at Harvard, as the Aeolians did.

Wilson says he’s ready to go.

“Send the invitation and the welcome wagon,” Wilson said, “and I’ll be up there.”


A lost archive of Black history

Deborah Willis’ career as a photographer, curator, and historian began with a question she had as a college student: Where are the Black photographers?

While enrolled at the Philadelphia College of Art, Willis found that Black photographers were rarely included in history books. Black people, too, were under-represented in images — often included only when the photos displayed their struggle or subjugation.

“I knew there was a lot missing,” Willis said at a recent ArtsThursday event at the Hutchins Center for African & African American Research. “I was encouraged by [curator and professor] Anne Tucker to continue thinking about it and continue working.”

“I knew there was a lot missing.”

Deborah Willis

Willis, the University Professor of Photography & Imaging and Social & Cultural Analysis at NYU, attempted to fill that gap in her 2000 book “Reflections in Black,” a landmark collection of photography celebrating a wide spectrum of African American life from 1840 through the 20th century.

Twenty-five years later, Willis discussed the anniversary edition of the collection before a Harvard audience, delving into her personal history and that of Black photography in the U.S.

One theme of Willis’ talk was the painstaking process of collecting and archiving photographs. Many photos included in Willis’ original and updated book had been hidden or undeveloped before her efforts. Some were held by the relatives of photographers who had passed away. Others emerged unexpectedly from archives, where they had been lost.

She began by showing a picture that a friend had noticed at a memorial service. It showed a large crowd at the funeral of pianist and composer Duke Ellington. In the front, holding a camera, was a young Willis. No one had noticed for decades.

Willis described her experience at the event, held at St. John’s Cathedral in New York City. “Of course, I lost my camera and the negative, so I have no record,” Willis said. “This is why it means so much to see this here.”

Showing off pictures of her childhood home, Willis described her upbringing in North Philadelphia. She spent countless hours in her mother’s beauty shop, where women from the neighborhood gathered to talk. “They shared moments of disappointment in their lives, but they also shared moments of love,” she said. “Mom’s place was a secure, safe place for them.”

Her father was a policeman, tailor, interior decorator, amateur photographer, and a World War II veteran who used the GI Bill to study “everything that he could to create a life for his family.”

Willis showed one of the first photographs that she ever took — a Christmas scene that featured her doll, Susie. Later she presented one of her early undergraduate photos — depicting couples, grandmothers, and mothers looking out the windows of an apartment building. “I have been photographing homes for a long time,” Willis said, “and I’m really connecting to the idea of what it meant for us to acknowledge our communities.”

The photographs Willis showed, many of which feature in her collection, often reflected similar themes: love, the family, home — sentiments that she hoped to represent in African American visual history.

Unearthing them was often difficult. She recalled hearing about one notable exhibition whose photos seemed to have been lost. When she visited the Library of Congress to search for them, she was told that there was no information available. She continued the research anyway, until, one day, a librarian called and said she had found 350 photographs of Black communities produced by African American photographer Thomas Askew of Atlanta.

In another instance, the daughter of photographer Richard Roberts, who took pictures of South Carolina’s Black middle class, told Willis how the family had saved glass plate negatives of her father’s work in the crawl space of the house for many years.

Other photos Willis showed, like one of a few young girls outside an ice cream parlor, provided an alternative vision of African American life in the 1960s, typically dominated by photos of strife and protest. “We had an opportunity to see that young girls were part of the marches,” said Willis, “but they’re also having this casual afternoon, eating ice cream and sharing their moments with their stockings on after church.”

After the presentation, Sarah Lewis, John L. Loeb Associate Professor of the Humanities and associate professor of African and African American Studies, lauded Willis for demonstrating the “importance of collaboration for the entire field.”

“You have created the world in which I teach from, that we are living in,” Lewis said. “It just moves me so much.”

As for Willis, she says her work uncovering lost history continues.

Just recently, she found new photos of aviator Bessie Coleman from the Hooks Brothers commercial photography studio in Memphis.

“So we can imagine that there are all of these photographs in somebody’s cabinet, and in cards, and in family albums. The families who are holding on to these images will unpack more and more each time.”

When a fictional character becomes too real

Why Catherine Lacey can’t avoid ‘terrifying’ disclosures on the page and every story feels like her last

4 min read

For Catherine Lacey, fiction is a vehicle for discovering personal truths.

“When I start trying to make choices about what to reveal or conceal, it just doesn’t work,” the author said in a recent “Writers Speak” event hosted by Harvard’s Mahindra Humanities Center. “When I try to keep [the personal] out, it gets in anyway, or the book will refuse to be written.”

Lacey’s critically acclaimed debut novel “Nobody Is Ever Missing” provides an early example of the writer putting herself in her prose, even subconsciously. In the story, the main character loses her adopted sister to suicide. Between her finishing the book and its publication, Lacey’s stepsister died as a result of substance use — something the author couldn’t have predicted but nonetheless grappled with on the page, she said.  

“I didn’t have an adopted sister, I didn’t know anybody that had killed themselves, but my stepsister died by suicide — is the simplest way to describe it — after I had finished the book, and it was something that had been present in my life for about five years before,” she said. “It was present in the family and something everybody knew that they didn’t want to know. And I think those are the kinds of things that come out in fiction when a voice starts to feel like — ‘This is me, but it’s not me’ — and it does feel authentic, but I don’t know where it’s coming from.”

Especially as a young writer, Lacey noted, it wasn’t easy to bring a narrator to life. Now, she said, she knows that when her writing strikes an emotional chord, she’s doing something right.

“It’s terrifying for something to possess a voice,” she said. “It’s terrifying to have disclosures on a page. That even though they’re through a fictional character, it somehow reflects something about you that maybe you don’t even want to expose.”

Even still, Lacey said, she sometimes isn’t cognizant of how much of herself she reveals through her characters.

“I don’t tend to know what the book is about until it’s about to come out, and then a couple months before I realize it’s generally way more personal than I would have thought,” she said. “And if I had been the person in charge of making decisions about what we’re going to write about, what parts of ourselves are going to go in this book, I wouldn’t have put any of them in.”

The short story, in Lacey’s view, is the purest means of letting a narrative come together organically. Her first collection of stories, “Certain American States,” was released in 2018, and “My Stalkers” is forthcoming in 2027.

“When I hear poets talk about writing poems, this is like when you hear flowers talk about being flowers or something … it’s like something happens to them,” Lacey said. “And I think the story is the closest I can get to something happening to me.”

When the characters in a story or the scenes click for Lacey, it’s a quick process from start to finish: “It’s all I can think about for a week or two or three weeks, or however long it takes.”

The characters in “Rate Your Happiness,” published earlier this month in The New Yorker, were bouncing around in her brain for years, she said, waiting for the right threads to connect them. When the scene came to her, all the pieces fell into place.

“There’s just something about suddenly being like, ‘Oh, that’s the thing that I needed,’ that once that was in, I knew that was going to be part of the story — it just spawns everything else,” she said.

But the rush of seeing a story come to life never lasts for long,

“Every time I finish a story, I’ve been like, ‘That might be the last one I ever have,’ because it never really feels like anything else is going to feel like that,” she said. “It’s the magic that helps me not feel like I have a job.”


What to make of ‘AI psychosis’?

What to make of ‘AI psychosis’?

‘Until we know what the term really means, we can’t even begin to understand what’s happening.’

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 role in 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 new walking tour connects all those buildings, Martin noted.

“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 up

Gene therapy yields lasting gains for patients with inherited deafness: ‘How well it worked is really amazing.’

5 min read

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 West

Megan Kate Nelson’s new book challenges myths of American frontier, finds more diverse, complex saga

5 min read

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

5 min read

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.”

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 & 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.”

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?”

Single-minded pursuit of profit can get firms in trouble. Same thing with AI.

Researchers see lesson for lawmakers, executives as systems asked to run business, maximize gain resort to unethical, fraudulent tactics

5 min read

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.

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 court

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

6 min read

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.

Annual 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.

A group of cybersecurity experts were recently brought together for a Berkman Klein Center for Internet and Society discussion, during which all agreed that it’s high time for business and government leaders to regulate the tech — before it’s too late.

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.”

Moreover, cybercriminals have made alarming progress in phishing attacks over recent months, using AI to fine-tune targets and craft messages.

“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.”

“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.”

Across multiple national studies, HSDM researchers found that 24.7 million people live in dental care shortage areas and that 49.3 million U.S. adults lack public transit access to a dental clinic. The studies also found that access to specialty care is even more uneven: more than 98 percent of dental specialists practice in urban areas, leaving many rural communities with limited or no nearby specialty services.

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.

“Where you live can determine whether you receive timely treatment — or end up in the emergency room.”

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.”

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 truth

Psychedelics and the search for truth

Legal scholar sees common interests with law, religion, humanities

5 min read

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.” 

The annual Psychedelics Intersections Conference is a collaboration among the Center for the Study of World Religions at Harvard Divinity School; the Mahindra Humanities Center at the Faculty of Arts and Sciences; and the Petrie-Flom Center for Health Law Policy, Biotechnology, and Bioethics at Harvard Law School.

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.

‘She took those kids and left before he got home from work.’

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.

Small Town Girls book cover.

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 

4 min read

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.

Michael Sandel and Ronald Reagan debate 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.”

“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.”

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.

Cora Dvorkin, professor of physics in the FAS


Passion and purpose

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

8 min read

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. 


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.

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, an independent conservator and guest lecturer at NYU’s IFA, holds a pair of night vision goggles up to artwork in the Harvard Art Museums. The goggles 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.

Barro and Riccardelli showed examples of VIL imaging of works containing Egyptian blue in Harvard galleries: a Persian relief from the fifth century B.C., a foot panel from an Egyptian coffin, a composite funerary portrait of a man from Roman Egypt, and a cylinder seal with imagery of an archer shooting a winged bull.

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.”

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.

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

4 min read

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.

Two years later, Congress did so, passing the Lily Ledbetter Fair Pay Act.

“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

7 min read

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.


Fabricating a forest

Sydney Kaye

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.”


Hands-on, in art and medicine

Maya Lakshmi Srinivasan
General Surgery Resident, Harvard Medical School

“Panacea,” linocut on paper

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’

David Sekoll
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 disease

Specialist 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.


Why are communities pushing back against data centers?

Tech, data policy expert says concerns legitimate over rising power rates, water use, environmental issues amid mushrooming growth

Why are communities pushing back against data centers?

Tech, data policy expert says concerns legitimate over rising power rates, water use, environmental issues amid mushrooming growth

8 min read

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 public opposition 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-being

New study of residents of 22 nations finds psychological, pro-social, character changes

4 min read

Can forgiving someone today leave you with an improved sense of well-being a year from now? A new study of residents of 22 countries says yes.

The caveat, though, is that the size of the impact varies by nation, as does its nature.

Researchers with the Human Flourishing Program at Harvard’s Institute for Quantitative Social Science enrolled more than 200,000 participants to complete annual surveys about forgiveness practices and 56 measures of well-being one year later.

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, 94

Memorial Minute — Faculty of Arts and Sciences

4 min read

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.’

3 min read

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.

The 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. 

Kimmie Ng wants to know why. 

“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.
