Radiolab for Kids

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...

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...

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...

The honeybee. The ever-important pollinator for our plants is disappearing. Some call it the silence of the bees, others call it colony collapse disorder. Dr. Sammy Ramsey, our official bug correspondent, wondered, could it be due to parasites? And if so, how do we catch all of them? This question takes Dr. Sammy to the heart of a jungle in Bangladesh to look for overlooked honeybees impervious to parasites. The only problem? He ca...

Middle schooler, Aanya, has an up-close encounter with a squirrel in the school yard, which leads her to an obsession with one of North America's most common critters. She tells host Lulu Miller all about the overlooked superpowers of squirrels, including one squirrel who lives way up in the Arctic, where the weather gets so cold the squirrels who live there drop their body temperatures down below freezing and somehow, miraculously...

As dead as they seem, tree stumps are hubs of life and relationships. From stumps to snags, deadwood provides habitat for rodents, falcons, insects, and even humans! Stumps hold together the forest floor, give hunting perches to birds of prey in flatlands, prevent erosion and the encroachment of invasive species, usher in sunlight, provide nutrients, can be wells of renewable fuel, and hold onto stories human beings might have forg...

In the game of life, every species is like an action figure. You got your dogs and your dung beetles, your bald eagles and your blueberries. And for a long time scientists believed it was pretty much impossible for those action figures to mix and make a new kind of action figure that was able to have its own babies (dog beetles? Baldberries? Nah). But, today we tell the story of a four-legged beast in Kentucky whose existence is up...

The ocean can be a scary place: the waves are so strong, the water so deep. But surfer and illustrator AJ Dungo tells the story of an earthling who figured out how to walk on water and literally defy the rules of gravity. If you want a big SPOILER, here it is: It’s only human for the season, the grandfather of modern-day surfing, Duke Kahanamoku. Duke’s great grandniece, Heather Kina’u Paoa tells us about what Duke’s life was reall...

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...

High above the banks of the Mississippi river, a nest holds the secret life of one of America’s most patriotic creatures. Their story puzzles scientists, reinforces indigenous wisdom, and wows audiences, all thanks to a park ranger named Ed, and a well-placed webcam. If you want to spoil the mystery, here ya go: it’s a bald eagle. Actually, it’s three bald eagles. A mama bird and daddies make a home together for over a decade and g...

A singing entomologist, Dr. Sammy Ramsey, and a biologist with a knack for inventing things, Dr. Paul Mireji, tell us about one of the most fearsome animals on our planet. If you want a SPOILER of what it is, read on: It sucks our blood, spreads diseases; it's the tsetse fly. Both Sammy and Paul were afraid of this creature, but share the story of what can be gained by looking close at what scares you. In the case of the tset...

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. 

The moon has disappeared. Ok, just kidding. Happy April Fool’s Day. But what if the moon actually vanished?

After songbud Alan saw a movie about stealing the moon, he wondered what would actually happen if the moon disappeared. He found the perfect person to talk to – Mika McKinnon who has a masters in disasters. We learn about eerie silences, ocean stench, hurricanes, and ecosystems in total flux. 

Also a whole new season of Terrest...

If someone calls you crabby, it’s not a compliment – they’re calling you grumpy, grouchy or snappy. But let’s reconsider this stain on the humble crab’s reputation. Look closely at a crab’s gnarled shell and you’ll see an incredible creature. Today, we bring you two very different crab stories. The first comes from former Radiolab producer Rachael Cusick about a woman who replicated the ocean to breed hermit crabs. Next, how crabs ...

St. Patricks day is coming up. People worldwide will wear leprechaun hats and celebrate the luck of the Irish. But what about the luck of lobsters? Today we have a story about the biggest, luckiest lobster we have ever heard of — Nick. As lobsters age, they keep growing bigger and bigger. They don’t wear out or get sick like most other creatures do. The most common way they die is through accidents.

One day a woman named Bonnie went...

When wildlife conservationist Alan Rabinowitz was a boy, he had a stutter. Strangely, his stutter vanished when he spoke to animals. One day, when his father took him to the Bronx Zoo, Alan saw a majestic jaguar and made a promise to it. He spent the rest of his life fulfilling that promise.
