(And in case you're wondering, she shares how you can become a radical street librarian, too.) Hosted on Acast. See acast.com/privacy for more information.

If you ate bread this week (or cooked with salt and oil), you probably benefited from something millions miss out on: food fortification. Social entrepreneur Felix Brooks-church is on a mission to solve "hidden hunger" — malnutrition caused by a lack of nutrients — by fortifying everyday foods for regions of the world hit hardest by food insecurity. Laying out a pragmatic vision to improve food systems globally, he reminds us that hunger doesn’t always look like an empty plate. Hosted on Acast. See acast.com/privacy for more information.

Most of the technology powering life in Europe today — chatbots, the cloud, digital infrastructure — is owned by companies in the United States. Writer and curator Bruno Giussani makes the case that Europe's reliance on American technology has crossed the line from convenient to risky. His answer isn't to go it alone, but to build something the continent currently lacks: a real alternative, rooted in a different model. "Technology that does not spy on you — that should be Europe's digital difference,” he says. Hosted on Acast. See acast.com/privacy for more information.

What do radio personality Ira Glass, New York City mayor Zohran Mamdani, and your host Chris Duffy have in common? They all have practiced an unexpected skill that makes them more human—improv comedy. And they learned it from master improv teacher Rick Andrews. Rick joins Chris to discuss the life lessons they learn from giving up control and practicing how to “yes an” in conversations. They also modeled improv games such as “Alibi,” “7 Things,” “Fortunately and Unfortunately,” and more, so you can sprinkle some improvisational silliness to build better communication and trust in your work and personal life.

Over the course of hundreds of scuba dives, marine biologist Ayana Elizabeth Johnson fell in love -- with a fish. In this ode to parrotfish, she shares five reasons why these creatures are simply amazing (from their ability to poop white sand to make colorful "wardrobe changes") and shows what's at stake -- for us and them -- as climate change threatens the future of coral reefs.

What if we could hear nature's ultrasonic communication -- and talk back? From a bat's shrill speech to a peacock's infrasound mating call, conservation technology researcher Karen Bakker takes us through a sound bath of animal noises that are far outside humanity's range of hearing, demonstrating how artificial intelligence has translated the incredible complexity of nature's soundtrack. She asks us to consider the moral weight of such transformative technology and explores the futuristic opportunities presented for conservation, interspecies communication and more.(This episode originally aired in 2024.)

The ocean plays host to a peculiar party of wild, marine sex life that's perhaps quirkier (and kinkier) than you can fathom. But is human behavior interrupting these raunchy reproductive acts? Take a deep dive with marine biologist Marah J.
