A cosmologist's guide to the end of the universe | Katie Mack and Debbie Millman

Irish musician and songwriter Wallis Bird received her first guitar at six months old and has been chasing music ever since. After her TED2026 performance of three genre-bending original songs, Wallis sat down with TED music curator Anna Bulbrook – a musician herself – to talk about the cosmic energy she taps into on stage, and what drives her songwriting. Their conversation explores her lifelong pull toward music, the stories hidden inside her songs, and how creativity can heal. It's woven through Wallis's electrifying, deeply moving performance, as she sings about joy, grief, social struggle, and what it takes to use music to bring people together, even when the world gives you every reason to look away.To learn more about Wallis and her music, visit www.wallisbird.com.

Rainn Wilson was a late bloomer: he landed the role of Dwight Schrute on The Office after over a decade of struggling as an actor. But success didn’t solve all of his problems -- and it even created some new ones. In this live conversation for the Authors@Wharton series, Adam asks Rainn about his unlikely journey to stardom and how it led him into exploring the insights that philosophy, psychology, and the world’s great spiritual traditions can offer on modern life’s existential questions. They also discuss Rainn’s favorite moments from The Office and do some improv when Dunder Mifflin invites a certain organizational psychologist to talk to Dwight.

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.
