Radiolab for Kids

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 bea...

Over a billion lightyears ago, in the darkness of outer space, a collision of black holes sent out a fleet of invisible waves that were headed right toward planet Earth. The waves were so powerful they could ripple spacetime but most people on Earth didn't believe the waves were real. SPOILER ALERT: The waves are called gravitational waves and…they are real! Astrophysicist Dr. Wanda Díaz Merced tells the story of what happened when...

Pizza is one of the world’s most beloved foods. But as much as we love the way it tastes, the secrets of its ingredients are even yummier to discover. We explore the surprising sounds tomatoes make when they’re stressed, how wheat became integral to human survival and how mold is sometimes... delicious?  This episode also features live tap-dancing, mind-melting cheese facts and what might be the Songbud’s catchiest song yet.

Special...

We’re back with an episode from the Radiolab archive. Horseshoe crabs have been around for a long time. They outlived the dinosaurs, survived all mass extinctions and witnessed the sprouting of the Earth’s first trees. The secret to their longevity? Their baby blue blood. Which has been saving both their lives and ours. 

Lulu and Radiolab co-host, Latif Nasser,  head to one of these bleeding facilities to learn how horseshoe crab bl...

A color-changing creature many people assumed to be brainless outsmarts his human captors. SPOILER: The creature is an octopus! Author Sy Montgomery tells the story of one octopus named Inky who makes us question who we consider intelligent (and kissable) in the animal kingdom. 

Learn about the storytellers, listen to music, and dig deeper into the stories you hear on Terrestrials...

Today, we splash into the Hudson River Park with our Songbud to meet all kinds of crabs. With Siddartha and Carrie from  the Hudson River Park, Alan puts on waterproof rubber overalls, gets his hands dirty in the river and dives into the secret lives of Hudson crabs.

Plus, CRAB WEEK is going on right now in New York City! It’s an annual shell-ebration that highlights the crabs of the Hudson River. Scuttle by for crabtastic activitie...

Today we’re bringing you a live episode we taped in Boston. It’s about clam chowder. We’re sharing it now because we’re doing ANOTHER LIVE SHOW at Little Island in NYC on August 6th + 7th - and that one’s about PIZZA! The show’s free. There will be pizza. Join if you’re in NYC (or make this the reason you visit). Check out all of our other performances here.

Lulu is a Bostonian who has never had clam chowder. Read that again. For so...

The Greenland shark is ugly. Its eyes look cloudy and dead. Its snout and fins are stubby. Its meat is poisonous. And that may be part of why most people have overlooked these sharks for so long. But there was a rumor circulating among Greenland villagers that this deepsea dweller could survive for centuries. Scientist John Steffensen went on a hunt to see if this was true and discovered that the Greenland shark can live for more t...

We’re doing a bunch of LIVE SHOWS at Little Island in NYC on August 6th-7th. For free. Come join! Check out all of our performances here.

Today we’re bringing you an episode we taped LIVE at The Greene Space at WNYC. In a room filled with all types of critters — scorpions, hissing cockroaches, a tarantula named Isabel and our main star… the jumping spider. Entomologist and bug lover Dr. Sebastian Echeverri tells us all about his lov...

On the outskirts of the Nevada desert, a young dog named Hades jumped his fence and ran away from home. His family lost hope, until one night, they saw Hades on the news. For almost seven months, he had been sleeping, eating and howling with a pack of coyotes.

We usually view coyotes as vicious, bloodthirsty beasts. But turns out, they can be pretty friendly. They form unlikely alliances with other animals all the time. They’re so f...

Coquí frogs are synonymous with Puerto Rican identity. Residents of the island doze off to the high-pitched calls of coquís from dusk to dawn. There are even playlists of hours of coquí calls that lull listeners to sleep. 

That’s why ProducerBud Ana, a proud Puerto Rican, was confused when she saw a poster calling for the eradication of coquí frogs at a Hawaiian airport. Turns out, residents of Hawaiʻi see coquís as a nuisance, disr...

Today we bring you a story stranger than fiction. In 2006, paleobiologist Natalia Rybczynski took a helicopter to a remote Arctic island near the North Pole, spending her afternoons scavenging for ancient treasures on the ground. One day, she found something the size of a potato chip. Turns out, it was a three and a half million year old chunk of bone. SPOILER ALERT BELOW.

Keep reading if you’re okay with us spoiling the surprise.

Farts. Trouser trumpets. Sulfur squeaks. Or toots, as Lulu insists on calling them. Smelly bubbles of air we don’t like to talk about. But Songbud Alan and Producerbud Ana are not ones to shy away from the stinky sidelines of science. 

First, they take us to a concert hall to meet a FARTchestra and hear how behind some of the world’s greatest works of art lies the power of farts. Next Dr. Juan Pablo Zhenlio takes us through the ecos...

Rats have a bad reputation. They’ve been called evil, terrifying and wicked. The lowliest and most abominable of creatures. Songbud Alan felt the same way until he heard of one rat from Tanzania named Magawa. We meet Pendo, Magawa’s human friend and trainer, who wanted to train Magawa for a battlefield of sorts. A battle to save human lives. 

You see, some countries have explosive landmines placed there during war. When the war is o...

Terrestrials returns Thursday, April 17th with a brand-new season!

This spring, we’re diving into the wonderfully weird. Get ready to meet some of the fiercest, strangest creatures on Earth—from Hawaiian jungle goblins to New York City’s elusive sewer beasts to nine-foot-tall misunderstood snow monsters. When we take a closer look at the creatures we usually fear, we often discover a little magic, wonder, even friendship!

Join host L...

On January 29, in places like China, Malaysia, Korea and Chinatowns across the globe, dragons will rise in the form of massive puppets. Today we bring you a special Terrestrials episode on dragons to understand what they have to do with the New Year, what the dragon myth means, and explore the tiny chance that dragons could have ever been real. 

First, we meet Mr. Lu Dajie, one of China's most renowned dragon dancers, who tells us a...

Artist Ashley (Ash) Eliza Williams was so shy growing up that they found it hard to speak to people.  Instead, they withdrew from the world of humans and found comfort in the forest, where they spent hours exploring, scavenging, and collecting — eventually discovering lichen. They began painting portraits of lichen’s wild, colorful, and fuzzy shapes.

 In time, Ash learned that lichen is actually a composite organism, a mixture of tw...

Have you ever seen an island on a lake? On an island? On a lake? On another island? Josh Calder has. Working in a dusty room of a library, he first saw one on a map, and has been fascinated with these “recursive islands” ever since. Song bud Alan Goffinski takes us on a wild journey into these secret bullseyes hiding all over planet Earth. We learn from ecologist Elba Montes why recursive islands breed species found nowhere else on...

BLAST OFF! NASA just sent a spacecraft to Europa, one of Jupiter's moons, and on the side of that spacecraft, they included a poem. Not just any poem — a poem by U.S. Poet Laureate Ada Limón. A poem that’s supposed to represent all of humanity to the universe. No biggie. 

Host Lulu Miller opens up the floor to kids from all over the country to ask Limón and NASA scientist Cynthia Phillips questions about the mission, outer space, po...
