Episode notes
In this episode, first aired in 2014, we examine three very different kinds of black boxes—spaces where we know what’s going in, we know what’s coming out, but can’t see what happens in-between. From the darkest parts of metamorphosis to a sixty-year-old secret among magicians, and the nature of consciousness itself, we shine some light on three questions. But for each, we contend with an answerless space, leaving just enough room for the mystery and magic, always wondering what’s inside the Black Box.

Life in a Barrel
This 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…

Antibiotic Apocalypse
Doctor 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. This live show, performed in New York City and also in Little Rock, Arkansas, is part of a series we’re doing with Avir that we are calling “Viscera.” Each event is a conversation that takes the audience on a journey into a quirk or question or mystery inside of us, and…

Staph Retreat
A 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,…

Return of the Screwworms
If a species is horrible enough, do we have the right to kill it forever? Seventy years ago, a nightmare parasite feasted on the live flesh of warm-blooded creatures in North America: the screwworm. That is, until a young scientist named Edward F. Knipling discovered a crucial screwworm weakness and hatched a sweeping project to wipe them out. Knipling’s seemingly zany plan to spray screwworms out of planes all over the continent— with US taxpayer money— succeeded, becoming one of humanity’s biggest environmental interventions ever. Today, screwworms have been gone so long that none of us in…

Snail Sex Tape
In this episode, we consider a creature we often don’t think much about—the snail. And not just snails, but their sex lives. Which, as it turns out, is epic. There is persuasion and subterfuge, spaghetti penises and co-copulation. And this very surprising habit—erm kink—of making tiny arrows (actually!) and stabbing each other with them. Known as a “love dart,” these limestone daggers aren’t just a strange trick of nature—they have a deep evolutionary purpose. Special thanks to Menno Schilthuizen and Aaron Chase.EPISODE CREDITS: Hosted by - Molly WebsterReported by - Molly WebsterProduced by…

Gray's Donation
Before he was even born, Sarah and Ross Gray knew that their son Thomas wouldn’t live long. But as they let go of him, they made a decision that reverberated through a world that they never bothered to think about. Years later, after a couple of awkward phone calls, they go on a quest and manage to meet the people and places for whom Thomas’ short life was an altogether different kind of gift. We originally made this story back in 2015, but we wanted to play it again because we love that it brings a view of science that is redemptive, tender, and unexpected. Since we first released this…

Time is Honey
In the early 2000s, Sunil Nakrani felt stuck. Back then, websites crashed all the time. When Sunil noticed this, he decided he was going to fix the internet. But after nearly a year of studying the architecture of the web, he was no closer to an answer. In desperation, Sunil sent out a raft of cold emails to engineering professors. He hoped someone, anyone, could help him figure this out. Eventually, he learned that the internet could only be fixed if he paid attention to the humble honeybee. This is the story of the Honeybee Algorithm: How tech used honeybees to build the internet as we…

Kleptotherms
In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems. We first ran this episode in 2021: Five stories that run the gamut from snakes to stars. We start out underwater, with a species of snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Fahrenheit is a sound marker of health. Reported by - Lulu Miller…

Song of the Cerebellum
One spring evening in 2024, a science journalist named Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back of her brain called the cerebellum. A couple weeks later, her doctors took a bit of it out, assuring her it was just helping her with motor coordination — she might be a bit clumsy for a while, but she’d still be herself. But afterwards, she didn't feel like herself. So she dove into the dusty basement of the brain (and brain science) to figure out why. What Rachel found was a burgeoning new frontier in neuroscience. We learn…

You and Me and Mr. Self-Esteem
Most of us spend some part of our lives feeling bad about ourselves and wanting to feel better. But this preoccupation is a surprisingly new one in the history of the world, and can largely be traced back to one man: a rumpled, convertible-driving California state representative named John Vasconcellos who helped spark a movement that took over schools, board rooms, and social-service offices across America in the 1990s. This week, we look at the rise and fall of the self-esteem movement and ask: is it possible to raise your self-esteem? And is trying to do so even a good idea? Special…
