Math Vs Machine
In less than four years, mathematician Steve Strogatz watched AI go from flailing at basic arithmetic to solving problems that baffle the world’s best mathematicians. In September of 2026, Open AI announced it had solved a Millennium Prize Problem, one of math’s highest achievements. In short,...

A 4-Track Mind
In this short episode, first aired in 2011, a neurologist issues a dare to a ragtime piano player and a famous conductor. When the two men face off in an fMRI machine, the challenge is so unimaginably difficult that one man instantly gives up. But the other achieves a musical feat that ought to…

Grass Apes
When you think about grass, what do you think of? Pool parties? Suburbs? Allergies? What about: human history? It turns out, unassuming grass, which exists on every continent, has an epic story to tell. One of transforming the planet, and … us. From what we eat, to how our body might be shaped…

The Sweetest Thing
“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...

23 Weeks 6 Days
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...

60 Words
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…

Dolly Parton's America: Sad Ass Songs
The world lost a legend recently, and we wanted in some small way to pay tribute to the great Dolly Parton. So we’re playing you an episode from a series we had a small part in back in 2017, Dolly Parton’s America. The series kicked off with a simple question: How did the queen of the boob joke...

Patient Zero
The greatest mysteries have a shadowy figure at the center—someone who sets things in motion and holds the key to how the story unfolds. In epidemiology, this central character is known as Patient Zero—the case at the heart of an outbreak. This hour, Radiolab digs up an episode we first produced…

Nigel and the Real Gannet
In 2016, Chris Bell, a ranger with New Zealand’s Department of Conservation, was the sole human inhabitant of a small island off the west coast of the country, called Mana Island. He was there to take care of the island’s fragile and recovering ecosystem, including a colony of Australasian…

Red Herring
It was the early '80s, the height of the Cold War, when something strange began happening off the coast of Sweden. The navy reported a mysterious sound deep below the surface of the ocean. Again, and again, and again they would hear it near their secret military bases, in their harbors, and up…

The Shoe Thrower
When no one seems to be listening, how far do you go to be heard? In December 2008, George W. Bush made a surprise visit to Baghdad for a press conference. And at the very end of his remarks, a shoe came flying past his head. It was “the shoe heard around the world,” and countless jokes and memes...
-
Return of Alpha Gal
Several years ago, in 2016, we told a story about Amy Pearl. For as long as she could remember, Amy loved meat in all its glorious cuts and marbled flavors. And then one day, for seemingly no reason, her body wouldn’t tolerate it. No steaks. No brisket. No weenies. It made no sense: why couldn’t...
-
Neither Confirm Nor Deny
In an episode we first ran back in 2014, we explore how a sunken nuclear submarine, a crazy billionaire, and a mechanical claw gave birth to a phrase that has hounded journalists and lawyers for 40 years and embodies the tension between the public’s desire for transparency and the government’s…

The Holy Shiver
Lauren Brown gets goosebumps. A lot. Sometimes several times a day. When her partner, writer Carmen Maria Machado, noticed it...she couldn't stop thinking about it. Why does she get them in so many different situations? What’s happening in her body and what does it mean? We take that question and...
-
Atomic Artifacts
Back in the 1950s, facing the threat of nuclear annihilation, federal officials sat down and pondered what American life would actually look like after an atomic attack. They faced a slew of practical questions like: Who would count the dead and where would they build the refugee camps? But they...
-
The Gondolier
Back in 2017, reporters Kristen Clark and David Conrad came to us with a story that dug into the difficult and often dark places discrimination creates. We start in Venice, Italy, where they meet gondolier Alex Hai. On the winding canals in the hidden parts of Venice, we learn about the nearly...

This is Your Brain on Hormones
After reading something that said her menstrual cycle changes her brain each month, Senior Correspondent Molly Webster goes on a reporting mission to see if that’s true, and, if so, how. This journey into sex hormones and the brain involves females and males, and exacting self-experimentation. It...

Bonus: Wild Animal Dads from Terrestrials
In honor of Father's Day, here is a family friendly bonus episode from our kids' podcast Terrestrials. What does it really mean to be a dad? In the animal world, fathers have long been painted as aggressive or absent. At best providers and protectors, but certainly not caregivers. And yet for…

Oliver Sipple
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…

This American Roach
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,...
-
Worth
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...
-
Your Friendly Neighborhood Hookworms
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...

The Bad Show
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...

What is a Pig Worth?
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…

Forests on Forests
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 Resistance of a Cow
There’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 Builders
In 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...
-
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...
-
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:...
-
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...
-
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...
-
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...
-
Black Box
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...

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…

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…

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...
-
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...
-
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...
-
The Punchline
This episode, first aired in 2019, brings you the story of John Scott, the professional hockey player that every fan loved to hate. A tough guy. A brawler. A goon.

Brain Balls

Moon Trees
In 1971, a red-headed, tree-loving astronaut named Stu ‘Smokey’ Roosa was asked to take something to the moon with him. Of all things, he chose to take a canister of 500 tree seeds. After orbiting the moon 34 times, the seeds made it back to Earth. NASA decided to plant the seeds all across the...
-
Fertility Cliff
As she -- and her friends — approached the age of 35, senior correspondent Molly Webster kept hearing a phrase over and over: “fertility cliff.” It was a short-hand term to describe what she was told would happen to her fertility after she turned 35 — that is, it would drop off. Suddenly…

The Good Show
The standard view of evolution is that living things are shaped by cold-hearted competition. And there is no doubt that today's plants and animals carry the genetic legacy of ancestors who fought fiercely to survive and reproduce. But in this hour that we first broadcast back in 2010, we wonder...
-
The Alien in the Room
It’s faster than a speeding bullet. It’s smarter than a polymath genius. It’s everywhere but it’s invisible. It’s artificial intelligence. But what actually is it? Today we ask this simple question and explore why it’s so damn hard to answer. Special thanks to Stephanie Yin and the New York...

Shell Game: Minimum Viable Company
A year ago we brought you a show called Shell Game where a journalist named Evan Ratliff made an AI copy of himself. Now on season 2 of the show, Evan’s using AI to do more than just mimic himself — he’s starting a company staffed entirely by AI agents, and making a podcast about the experience....

The Wubi Effect
When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason…
