How did the Harvard PhD experience influence W.E.B. Du Bois, the man who would become one of the leading Black activists and intellectuals of the 20th century? And what connections did he make in the vibrant Black community outside of campus? Join us as we explore these questions in the first of a two-part conversation with New York University professor and National Humanities Medal recipient David Levering Lewis, winner of the Pulitzer Prize for his two-volume biography of W.E.B. Du Bois.

As states around the country face off in a contest of Gerrymandering, what is the future of voting rights in the United States? Will the Supreme Court nullify what’s left of the landmark Voting Rights Act of 1965? How will accelerating climate change effect US politics? And what might happen in the all-important election of 2028? Harvard's Frank G. Thomson Professor of Government Stephen Ansolabehere, PhD '89, an expert in public opinion and elections and a consultant for the CBS News Election Decision Desk, recently joined Dean Emma Dench of the Harvard Kenneth C. Griffin Graduate School of Arts and Sciences to address these and other questions in a discussion of elections, energy, and the public mood.

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.
