Worth
6d ago01:11:58Summary readyThis 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
2w ago00:46:17Summary readyFor 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 Special thanks to Ethan Hein for the use of his remix of Mozart's Piano Concerto No. 21. Plus, Doris Pierce, and Dan and Alice Hadley.

Summary
The Bad Show
3w ago01:06:38Summary readyWith 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?
4w ago00:42:48Summary readyIn 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 2400:19:50Summary readyFor 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.

We first learned about the magical world of the canopy from this beautiful video. It features Korena Mafune’s research up in the treetops, as well as the people who have dedicated their lives to saving what’s left of the old growth forests. We highly recommend checking it out!

The Resistance of a Cow
Apr 1700:51:03Summary readyThere’s something rotten in the cows of Denmark. And Minnesota. And Wisconsin. And Idaho. What could cause a previously thriving herd of majestic dairy cattle to stop drinking water and start drinking … urine? A Danish farmer calls a special investigator, who takes one look at his farm and nopes the heck out of there, refusing to return, citing “bad energy” coming from something nearby … a big building covered in Viking runes. It’s not magic. It’s an invisible force that’s far more common. And yet deeply mysterious. This episode plunges producers Matt Kielty and Simon Adler knee-deep in a decades-old dairy farm controversy, rooted in a fundamental suspicion of the invisible streams of electrons that keep our world humming.

The Builders
Apr 1000:30:00Summary readyIn an episode first aired back in 2025 on our sister show, Terrestrials, we take you on a musical journey all about beavers. Few mammals have a bigger positive impact on the planet than the beaver. With its bright orange buck teeth, the creature is an expert engineer that brings life wherever it waddles and even fights fires. Our story begins in the Bronx river, once known as the “open sewer” of New York City. After some humans decide to clean it up, we meet one of the river’s residents - José the beaver. We learn about the US government parachuting beavers out of planes into the mountains. And finally head to California where we discover how one beaver family saved acres of land from burning. Special thanks to author Ben Goldfarb, Christian Murphy from the Bronx River Alliance and Dr. Emily Fairfax. Terrestrials was created by Lulu Miller with WNYC Studios. This episode was produced by Ana González and sound-designed by Mira Burt-Wintonick. Our team includes Alan Goffinski, Joe Plourde and Tanya Chawla. Fact checking was by Diane Kelly.

Life in a Barrel
Apr 300:54:42Summary readyThis week, in an episode we first aired in 2022, we flip the Disney story of life on its head thanks to a barrel of seawater, a 1970s era computer, and underwater geysers. It’s the chaos of life. Latif, Lulu, and our Senior Producer Matt Kielty were all sitting on their own little stories until they got thrown into the studio, and had their cherished beliefs about the shape of life put on a collision course. From an accidental study of sea creatures, to the ambitions of Stephen J Gould, to an undercooked theory that captured the world’s imagination, we undo the seeming order of the living world and try to make some music out of the wreckage. (Bonus: Learn how Francis Crick really thought life got started on this planet).

Antibiotic Apocalypse
Mar 2701:01:07Summary readyDoctor and special correspondent Avir Mitra takes Executive Editor Soren Wheeler, plus a live studio audience, on a journey from the operating room to inside the body to the farm to the sewers and back again—searching for answers to an alarming threat to humanity’s existence as we know it: antibiotic resistance in bacteria.

Staph Retreat
Mar 2000:31:34Summary readyA strange brew that's hard to resist, even for a modern day microbe. In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives. But in this episode, originally released in 2015, we follow an odd couple, of a sort, to a storied land of elves and dragons. There, they uncover a 1,000-year-old secret that makes us reconsider our most basic assumptions about human progress and wonder: what if the only way forward is backward? Special thanks to Steve Diggle, Professor Roberta Frank, Alexandra Reider and Justin Park (our Old English readers), Gene Murrow from Gotham Early Music Scene, Marcia Young for her performance on the medieval harp and Collin Monro of Tadcaster and the rest of the Barony of Iron Bog. Can’t get enough of that sweet, sweet antibiotic resistance content? Then you’ll be over the moon about next week’s release. It’s the podcast cut of our most recent installment of our live show series called Viscera. This one features executive editor Soren Wheeler and Avir Mitra, and it’s all about how our millenia's-long war against bacteria came to a tipping point in this modern age.
