This Halloween, we’re going to the dark side. Deep in the darkest tropical forests, some of the world’s most elusive bats hang upside down in their winged sleeping bags. On a quest to find one of these flying mammals, Producerbud Ana ventures into a Puerto Rican forest and the back corridors of the American Museum of Natural History with Dr. Angelo Soto-Centeno. Why? Because while they may be scary and look kinda like Dracula, with their sharp fangs and beady eyes, these bats hold something crucial for humanity - the ability to repair entire ecosystems after some of the most destructive hurricanes ever. 

Terrestrials was created by Lulu Miller with WNYC studios. This episode was produced and reported by Ana González with sound design by Mira Burt-Wintonick. Our Executive Producer is Sarah Sandbach. Our team also includes Alan Goffinski, Tanya Chawla and Joe Plourde. Factchecking was by Emily Krieger.

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
