A Breakthrough in Studying Diseases of the Brain
Chronic traumatic encephalopathy, or CTE, is a neurodegenerative disease linked to repeated head injuries. It has been found in professional athletes, soldiers, and others who have experienced years of those traumas. New research from Harvard Griffin GSAS alumni Chanthia Ma and Guanlan Dong may help us better understand this condition. Their study looks at the smallest units of brain biology—individual neurons—and finds surprising clues written in the DNA itself. Using single-cell genome sequencing, they discovered that neurons in people with CTE carry distinctive patterns of genetic damage—patterns that may overlap with those seen in Alzheimer’s disease. In this episode of Colloquy, Ma discusses how her work not only sheds light on how brain trauma leads to long-term decline but also hints at possible shared mechanisms across different neurodegenerative conditions.

“Was the American Revolution a Civil War?” and Other Thorny Questions about the Nation’s Founding
Us against the redcoats. That's how we often think of the American Revolution. In Ken Burns’ latest film, scheduled to drop later this month on PBS, the acclaimed documentarian takes on that simplistic notion of the nation's founding and many others. The revolution was actually a civil war, Burns says, one that pitted Americans, including indigenous and Black folk, against each other as much as the British. So, what were the divisions among the inhabitants of the British colonies and their neighbors? How did they flare into war? How did a fledgling nation with no central government or standing army defeat the world’s largest empire? And what were the contributions of indigenous and Black people and women? Philip C. Mead, PhD ’12, former chief historian and head curator of the Museum of the American Revolution in Philadelphia, weighs in.

In the Snare of the Devil: What Really Caused the Salem Witch Crisis
“How long have you been in the snare of the devil?” That was the lose‑lose question asked of those—mostly women—accused of witchcraft in Essex County, where Salem Village was located, in 1692. According to the Cornell University historian Mary Beth Norton, PhD ’69, however, it was the accusers, rather than their targets, who were in the thrall of something powerful. In her 2002 Ambassador Award–winning book In the Devil’s Snare, Norton says that the Salem witchcraft crisis was driven not by a demonic force, but rather by the trauma of the nearby wars with New England’s Indigenous populations—conflicts that had been raging for many years and had left an indelible mark on many refugees who fled to towns on the North Shore of Massachusetts.

What Happens When Your Brain Goes to the Supermarket and Other Stories of Human Adaptability
We all want to live as long and as well as possible. Diet and exercise are crucial, but how can we make sense of the flood of information, which sometimes seems to contradict itself? More importantly, how can we adapt the information in ways that work for us as individuals?Know thyself, answers Duke University Professor Herman Pontzer, PhD ’06. Every body has a story, he asserts in his new book, Adaptable. So does every part of our body. The main characters are our organs and systems. The themes and plot are a mishmash of genes and our environment. The result is an astonishing amount of diversity across humanity, united by our common ability to adapt over time and place. Pontzer says that a deeper understanding of how our bodies evolved and how that process shapes our biology can help us better take charge of our health.

Living Tombs: Toward a Fluid Understanding of Architectural Space
2025 Harvard Horizons Scholar Sergio Alarcón Robledo explores ancient Egyptian architecture through an interdisciplinary approach that sits at the crossroads of archaeology, Egyptology, and architecture. By inquiring about the sensorial experiences of the past, the PhD student in Near Eastern languages and civilizations at the Harvard Kenneth C. Griffin Graduate School of Arts and Sciences seeks to understand why ancient funerary structures changed and evolved into monumental buildings. Collaborating with experts from Stanford University, Alarcón Robledo employed acoustic analysis to unravel how these ancient spaces would have shaped sound and, consequently, the human interactions that took place within them.
