How does stress affect the prefrontal cortex? In this episode of the YJBM podcast, host Delyar Khosroabadi speaks with Dr. Amy Arnsten, Albert E. Kent Professor of Neuroscience and Professor of Psychology. Dr. Arnsten shares the experience that sparked her interest in neuroscience, her journey as an undergraduate creating the first neuroscience major at Brown University, and what drew her to study the prefrontal cortex. She discusses dynamic network connectivity, the mechanism of action of guanfacine, and why prefrontal deficits begin to appear in middle age. Dr. Arnsten also offers fascinating insights on how exercise and a healthy diet can benefit the prefrontal cortex.

From tiny cowries to giant clams, seashells have gripped human imaginations since time immemorial. In her magnificent new book, The Sound of the Sea, journalist Cynthia Barnett tells the epic history of humanity’s interactions with shells and the soft-bodied animals who make them. These stories of how we have treasured, traded, plundered, and coveted shells reveal much about who we are and who we’ve been, both good and bad. Barnett’s deep research ranges from the awe-inspiring “great cities of shell” of the Calusa people in Florida, to the use of cowrie shells as currency in the Atlantic slave trade, to the decimation of mollusk populations due to climate change and over-harvesting. In this episode, we speak with Barnett about what she describes as our “world of shell,” what shells can tell us about our past, how they have shaped our present, and how the future of shells and their animal makers is tied to our own.

In “Beloved Beasts: Fighting for Life in an Age of Extinction,” science journalist Michelle Nijhuis chronicles the history of the wildlife conservation movement through the stories of the extraordinary people — both legendary experts and passionate amateurs — who shaped its evolution and expanding ambitions. Nijhuis introduces us to the Swedish scientists who devised the system of naming and grouping species that endures today, the rebel taxidermist who led the fight to save the American bison from extinction, the New York City socialite who demanded that the Audubon Society stop ignoring the gunning down of game birds by sportsmen, and more. These inspiring, dogged, and often flawed characters transformed both the ecological communities and ideas that we inherited. In this episode, we speak with Nijhuis about what we can learn from the stories of conservationists and their efforts to protect the wild animals that they loved, and the possibilities within a more equitable, inclusive fight to defend life.

Are plants intelligent? Can they think? Can they hear, see, feel, smell and taste? Throughout history, most Western philosophers and scientists answered those questions with a resounding “no.” Plants have long been treated as passive, inanimate objects that form the backdrop to our active lives, rather than highly sensitive organisms with intelligence and agency of their own. But on the cutting edge of modern science, this orthodoxy is being questioned by a group of daring and imaginative scientists — including our guest, Monica Gagliano — who think that plants are radically more sophisticated and sensitive than we’ve been giving them credit for. Gagliano pioneered the field of “plant bioacoustics,” the study of sounds produced by and affecting plants. The results of her groundbreaking experiments suggest that plants may perceive, solve problems, remember, and learn via mechanisms that differ from our own. In this episode, we speak with Gagliano about the profound implications of her discoveries and how listening to plants changed her understanding of the world.

Nonhuman beings, and the passionate people who study them, animate Ed Yong’s vast, award-winning and kaleidoscopically varied body of journalism. His vivid stories explore the lives of scientists, the origins of life, social policy, whale hearts, the sixth extinction, the individuals we lose when a species vanishes or populations shrink, and the communities of tiny microbial beings that make us ourselves. To be at all, Yong demonstrates, is to be in partnership with other animals. In this episode, we speak with Yong about the wonders and burdens of telling stories about the animal world.

Ever wonder what it takes to produce an award-winning food podcast? At a live event with us, Gastropod co-hosts Cynthia Graber & Nicola Twilley share about their fascinating journey using science and history to tell stories about food. In the conversation, the two cover everything from the twists and turns of some of their episodes, to the place of their podcast in food media (spoiler: what does Gastropod have in common with a frozen pizza documentary?). Plus, notes on communicating science well, and an audience Q&A with tips for aspiring food writers.

To keep up with Cynthia & Nicola’s work, subscribe to Gastropod on Apple Podcasts, Spotify, or wherever you get your podcasts, and follow @gastropodcast on Twitter and Instagram. Their latest episode on the ghost foods of generations past will leave you hungry for more!

Chewing the Fat is a podcast from the Yale Sustainable Food Program. We cover people making change in the complex world of food and agriculture. We’re home to brilliant minds: activists, academics, chefs, entrepreneurs, farmers, journalists, policymakers, and scientists (to name a few!). Taken together, their work represents a reimagining of mainstream food movements, challenging myths and tropes as well as inspiring new ways of collaborating.

The podcast is an aural accompaniment to our on-campus Chewing the Fat speaker series, aiming to broaden our content beyond New Haven. Episodes are released every two weeks, featuring interviews, storytelling and more.

On the farm, in the classroom, and around the world, the Yale Sustainable Food Program (YSFP) grows food-literate leaders. We create opportunities for students to experience food, agriculture, and sustainability as integral parts of their education and everyday lives.
