How much control do we truly have over our brain health? In this episode, Professor Kelly Lambert, a pioneer in the field of behaviorceuticals, discusses how environmental enrichment and positive anticipation physically reshape the brain.  Drawing on her celebrated research—including the world-famous "rat driving" studies—Professor Lambert discusses what we can learn about brain health from wild animals, the dangers of living in what she calls “brain bubbles,” and examines the critical role of authentic experience in building emotional resilience. She also offers a unique perspective on how small behavioral shifts can serve as powerful alternatives to traditional pharmaceuticals for improving mood and cognitive function.

The Phi Beta Kappa Book Awards are presented annually to three outstanding scholarly books published in the United States.  The 2025 winners are Charles King for his book Every Valley: The Desperate Lives and Troubled Times That Made Handel's Messiah; Stefanos Geroulanos for his book The Invention of Prehistory: Empire, Violence, and Our Obsession with Human Origins; and Ayana Elizabeth Johnson for her book What If We Get It Right? Visions of Climate Futures.  This year, the Book Awards Dinner was held in person in Williamsburg, VA in December 2025, where two of the three scholars discussed the impetus behind their books and the motives that keep them sleepless—and engaged—in liberal arts and sciences.

In this episode, Fred Lawrence speaks with Geraldo Cadava, Professor of History at Northwestern University and author of The Hispanic Republican. Cadava takes us from the childhood experiences that shaped his interest in complex identities—moving between the affluent suburbs of Irvine and the borderlands of Tucson—to his scholarly work on the contradictory nature of Latino identity. He shares the compelling story of his Panamanian-born grandfather, a veteran and copper miner whose partisan evolution from a Ronald Reagan voter to a staunch Republican demonstrates how individual political reasons can lead to deep ideological shifts. Cadava also previews his upcoming, ambitious project of writing a book encompassing the past 500-year history of Latinos, A Thousand Bridges, which argues that Latinos have historically been both victims and agents of empire.

In this episode, Fred Lawrence speaks with Ingrid Daubechies, James B. Duke Distinguished Professor Emerita of Mathematics at Duke University and a National Medal of Science recipient. Daubechies takes us from her childhood fascination with calculating multiples to her groundbreaking work on wavelets—mathematical building blocks that have revolutionized image and signal analysis. She talks about how her research helped the FBI compress millions of fingerprints, analyze seismograms, and even distinguish authentic Van Gogh paintings from forgeries. She also tells the story behind the whimsical Mathemalchemy Project, a collaborative art installation that celebrates the pure joy and creativity of mathematics.

In this episode, Fred Lawrence speaks with Professor Daniel Hungerman, a professor of economics at the University of Notre Dame. Hungerman discusses his unique academic journey, which led him to specialize in the economics of religious and charitable organizations.

In this episode, evolutionary biologist Douglas Emlen joins Fred Lawrence in a conversation about his research on extreme animal weapons— from the horns of a rhinoceros beetle to elk antlers. He discusses his family's scientific legacy, his early reluctance to follow in their footsteps, and how his childhood experiences in Kenya influenced his path. In his award-winning book, Animal Weapons: The Evolution of Battle, Emlen also explores the parallels between animal and human arms races. His interdisciplinary work connects biological evolution with military history, shedding light on the forces that drive the escalation of weapons in both human societies and nature.

For a lot of Americans, geography is just a middle school subject or a trivia night category at their neighborhood bar. But for Professor Kendra McSweeney, the “invisible field” of geography is a way to understand the relationship between people and their environment, from adaptation to climate change to how the drug trade impacts biodiverse forests in Colombia. In this episode, McSweeney highlights how her dynamic career as an academic has taken her from Canada to eastern Honduras, and talks about the thought process behind lectures such as “Viewing Political Ecology Through the Lens of the Tree of Heaven,” an enlightening take on the so-called invasive tree that is providing crucial shade in neighborhoods in the US.
