  • The Sweetest Thing
    Sep 18 2026
    “What is the sweetest thing in the world?” After co-host Latif Nasser’s sons ask him this deceptively simple question, he goes on a quest to find it. Is it a West African Katemfe berry? Or an industrial sugar substitute cooked up in a lab? Or an ingredient hiding in plain sight in all of our pantries? A simple mystery that will make you question what sweetness even is, how our tongues (and other body parts you wouldn’t expect) determine what we like, and how far you would go to taste something sweeter than anyone has ever experienced. Thank you to Latif’s sons for indulging us, to Nicola Twilley and Cynthia Graber at Gastropod, to Anni Laffitte, Nazli Parvizi at Museum of Food and Drink, to food icons Claire Saffitz and Sam Seneveratne who did a live show version of this episode with us at the Tribeca Festival. And thank you to Davy Gardner and his wonderful team of audio folks at the Tribeca Festival.Thank you to Jialin Deng who composed the song that was our ‘sonic seasoning’. And to Laura Rickman and everyone else at Columbia University’s Mortimer B Zuckerman Mind Brain Behavior Institute for hosting us.

    When Kelley Benham and her husband Tom French finally got pregnant, after many attempts and a good deal of technological help, everything was perfect. Until it wasn't. Their story raises questions that, until recently, no parent had to face… and that are still nearly impossible to answer.

    This hour, which we first released in 2013, we spend the entire episode on the story of Kelley and Tom, whose daughter was born at 23 weeks and 6 days, roughly halfway to full term. Their story contains an entire universe of questions about the lines between life and death, reflex and will, and the confusing tug of war between two basic moral touchstones: doing no harm...and doing everything in our power to help. Kelley has written about her experience in a brilliant series of articles in the Tampa Bay Times.

  • 60 Words
    Sep 4 2026

    We’re coming up on the 25th anniversary of the 9/11 attacks, and it had us thinking about an episode we produced in 2014. It’s the story of one sentence, written in the hours after September 11th, 2001, that has led to the longest war in U.S. history. We examine how just 60 words of legal language have blurred the line between war and peace.

    In the hours after the attacks of Sept. 11, 2001, a lawyer sat down in front of a computer and started writing a legal justification for taking action against those responsible. The language that he drafted and that President George W. Bush signed into law—called the Authorization for Use of Military Force (AUMF)—has at its heart one single sentence, 60 words long. Over the last decade, those 60 words have become the legal foundation for the "war on terror." In this collaboration with BuzzFeed, reporter Gregory Johnsen tells us the story of how this has come to be one of the most important, confusing, troubling sentences of the last two decades. We go into the meetings that took place in the chaotic days just after 9/11, speak with Congresswoman Barbara Lee and former Congressman Ron Dellums about the vote on the AUMF. We hear from former White House and State Department lawyers John Bellinger & Harold Koh. We learn how this legal language unleashed Guantanamo, Navy Seal raids and drone strikes. And we speak with journalist Daniel Klaidman, legal expert Benjamin Wittes and Virginia Senator Tim Kaine about how these words came to be interpreted, and what they mean for the future of war and peace.
