  • On the Media: American Emergency
    Jun 12 2026

    A little while back, our friends over at On the Media released a gripping and immersive reporting series about FEMA, the agency that is supposed to be there for all of us in the wake of disaster. In American Emergency (https://zpr.io/MtrUmJU3yEMW), OTM investigates how the agency tasked with saving America became distrusted, despised… and defunded.

    Today we talk to On the Media co-host Micah Loewinger about how this project came out, what reporting went into making it happen, and play a couple of fun and truly surprising bits of the story that the OTM team uncovered. And it’s a story that highlights the ideal and promise of good government, right alongside the frustration with bureaucracy and mismanagement, and of course the undercurrent of profound mistrust in governmental power.

    As natural disasters are getting more extreme and less predictable, this series makes sense of that tangle, and provides a prescient peek into FEMA’s future.

    Special thanks to On the Media. To hear Micah in person, talking more about the complex history of FEMA, join him on June 24th at WNYC's The Greene Space (https://wnyc.org/events/otm-fema).

  • Oliver Sipple
    Jun 5 2026

    One morning, Oliver Sipple went out for a walk. A couple hours later, to his own surprise, he saved the life of the President of the United States. In a story we reported back in 2017, we explain how in the days that followed, Sipple’s split-second act of heroism turned into a rationale for making his personal life into political opportunity. What happens next makes us wonder what a moment, or a movement, or a whole society can demand of one person. And how much is too much?

    Through newly unearthed archival tape, we hear Sipple himself grapple with some of the most vexing topics of his day and ours - privacy, identity, the freedom of the press - not to mention the bonds of family and friendship.

    Special thanks to Jerry Pritikin, Michael Yamashita, Stan Smith, Duffy Jennings; Ann Dolan, Megan Filly and Ginale Harris at the Superior Court of San Francisco; Leah Gracik, Karyn Hunt, Jesse Hamlin, The San Francisco Bay Area Television Archive, Mike Amico, Jennifer Vanasco and Joey Plaster.

  • This American Roach
    May 29 2026

    A couple summers ago, Radiolab reporter Alex Neason got out of the shower and almost stepped on her worst nightmare: an American Cockroach. It was flipped onto its back, struggling, and for a split second, Alex swears she felt the spiny tickle of its legs on the underside of her bare foot. And, like every other time she has come into contact with a roach, this sent her into a debilitating spiral of fear, anger, and disgust.

    This week, Alex tries to understand what might be behind her fear, in the hopes she can overcome it. And in doing so, Alex learns more about these so-called pests than she could have ever wanted to.

  • Worth
    May 22 2026

    This episode makes three earnest, possibly foolhardy, attempts to put a price on the priceless. We figure out the dollar value for an accidental death, another day of life, and the work of bats and bees as we try to keep our careful calculations from falling apart in the face of the realities of life, and love, and loss.

    In this story you’ll hear references to some of the issues that were on our minds when it first came out in 2014: wars in the middle east, drug costs and health care practices. Even as the exact shapes of these issues have evolved over the past dozen years, we feel the underlying questions are relevant and timeless: What is life worth? What about the earth?

  • Your Friendly Neighborhood Hookworms
    May 15 2026

    For most of human history, people went about their daily lives with a worm or two (or fifty) in their guts. Only in the past century, with pharmaceuticals and sanitation practices, have we made significant strides towards deworming the whole of humanity. And that’s typically been thought of as a good thing, because having too many worms in your body can–quite literally–suck the life out of you.

    But is it possible to have… too few worms? Science wonders if deworming ourselves has actually led to an increase in certain chronic diseases. On this episode, we dive into Necator americanus, a.k.a. the American Hookworm, and its mysterious relationship with each of us.

    We trace the hookworm’s 118-year journey from a demonized economic depressant, to its use as a desperate D.I.Y. immunosuppressant, to its potential as a medical treatment for a number of chronic diseases, everything from asthma to MS.

    We’re bringing back two stories from our 2009 episode Parasites plus new research on hookworms and autoimmune diseases, reported by Molly Webster

  • The Bad Show
    May 8 2026

    With all of the black-and-white moralizing in our world today, we decided to bring back an old show from 2011 about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us.

    Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why?

  • What is a Pig Worth?
    May 1 2026

    In 2017, Wayne Hsiung and a crew of animal rights activists from Direct Action Everywhere broke into a Utah pig farm run by Smithfield Foods, one of the largest pork distributors in the world. They were there to capture video of what they say were thousands of mistreated and abused animals kept in tiny metal cages barely bigger than their bodies. As they were leaving, they took two sick piglets out with them.

    Prosecutors in Utah charged Wayne with burglary and theft. What came next was the court battle that he wanted all along. During his trial, Wayne made a truly bizarre argument that forced the jury, and all of us, to stare straight at our complicated, sometimes uncomfortable relationship with animals. This week on the show, we grapple with the impossible question at the center of it: What is the value of a piglet?

    Special thanks to Kim Nederveen Pieterse, Nathan Peereboom, Jo Eidman, Sam Kozloff, Rachel Gross, Alex Allaux, and Joan Schaffner.

  • Forests on Forests
    Apr 24 2026

    For much of history, tree canopies were pretty much completely ignored by science. It was as if researchers said collectively, "It's just going to be empty up there, and we've got our hands full studying the trees down here! So why bother?"

    But then around the mid-1980s, a few ecologists around the world got curious and started making their way up into the treetops using any means necessary (ropes, cranes, hot air dirigibles) to document all they could find. It didn't take long for them to realize not only was the forest canopy not empty, it was absolutely filled to the brim with life. You've heard of treehouses? How about tree gardens?!

    This week, we bring you a story we first released in 2022. We journey up into the sky and discover forests above the forest. We learn about the secret powers of these sky gardens from ecologist Korena Mafune, and we follow Nalini Nadkarni as she makes a ground-breaking discovery that changes how we understand what trees are capable of.

    P.S. This episode is a layer cake of arboreal surprises (including the reappearance of a certain retired host.
