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. Read Alan Rabinowitz’s picture book: “A Boy and a Jaguar.” Radiolab was created by Jad Abumrad and is edited by Soren Wheeler. Lulu Miller and Latif Nasser are our co-hosts.

Next week is Valentine’s Day, but instead of talking about falling in love, we’re going to talk about falling cats and barrels. First, writer David Quammen tells us about a strange observation: cats are falling out of buildings in New York City. When a cat falls from less than five stories or more than nine stories, it usually survives. But when it falls from between five and nine stories, it suffers serious injury. Why? Physics has the answer. Then we meet Annie Taylor, the first person who went over Niagara falls in a barrel.

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.

Deep in the ocean lives a creature that can survive for centuries: the Greenland shark. But scientists discovered that the secret to their longevity comes at a cost — missing out on the best parts of life.

The honeybee. The ever-important pollinator for our plants is disappearing. Our official bug correspondent, Dr. Sammy Ramsey, takes us to the heart of a jungle in Bangladesh to learn how the most overlooked bees could possibly save all the honey bees in the world.

Middle schooler, Aanya, tells us her tale of an up-close encounter with a squirrel in the school yard, which turns into an obsession that leads her to learn about the arctic ground squirrel — the world’s only mammal that can drop its body below freezing and survive in a braindead state for weeks.

As dead as they seem, tree stumps are hubs of life and interrelationships. Scottish author, artist, and lover of tree stumps, Dr. Amanda Thomson, leads host Lulu Miller on a “tour de stumps,” a journey across space and time to learn about some of the most magical stumps on the planet. We learn how these overlooked dead things actually sustain the living.

A whole new season of Terrestrials is coming to the Radiolab for Kids feed! Enjoy a sneak peak of the people, places and creatures who have life-changing secrets to share.

Today on Radiolab for Kids, we eavesdrop on the world of animals. We bring you a story of two clever humans decoding the sonic cacophony of two clever animals in nature — Diana monkeys and prairie dogs. Both researchers decipher the “words” these animals are using to communicate to figure out what they talk about.

Today’s episode asks how scientists see the world. We bring you two stories — one about a math guy and a bug guy. First, how the math guy, or one of our country's greatest mathematicians, Steven Strogatz, first became enchanted with math as a kid. Then, a story about a human developing a soft corner (literally) for a fly that lived in his scalp — the botfly. Evolutionary biologist Jerry Coyne went on a research trip to Costa Rica and returned home with a botfly feeding on his flesh. His friend Sarah Rogerson was a little less charmed, and they both were surprised by the creature that ultimately emerged from his head.

The summer olympics are in full swing. Humans are racing against other humans from all across the globe. But you know the one race they don’t have? The one where a human competes against a horse. Radiolab for Kids is back with one of our favorite Radiolab animal episodes of all time where we head to that race in the desert of Arizona. Turns out it has everything to do with what gives us humans… our humanity. Also our butts.

Is there such thing as a good cage? Happy gorillas, deft landscape architects and neurologists show us that there just might be. We go back to the late 1970s to relive the moment when zoos began to change—literally the moment that the modern zoo was born, as embodied by a few tentative steps of a gorilla named Kiki.

The Terrestrials team is delighted to announce we’re coming back to the Radiolab for Kids feed! We’ve been traveling the globe in search of the strangeness right here on Earth. And we’ll be sharing a whole new batch of stories – and songs – in September.

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 upending scientific beliefs. If you want a big fat SPOILER, here it is: the creature in question is a mule! After almost 20 years of living her life as a hybrid (a mix between a horse and a donkey), believed to be incapable of having babies, Peanut the mule shocked the world by doing the impossible. Peanut’s owners, Teresa and Jerry Smothers, tell us the story of her life. Evolutionary biologist Dr. Molly Schumer explains how scientists’ understanding of hybrids has changed dramatically over the course of Peanut’s lifetime. And no mule episode would be complete without a cowboy-hatted mule packer leading us deep into the rocky trails of the American West on muleback to explain why mules are the best of both worlds of their parents.

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 really like. We learn about the physics of surfing, and how surfing is an escape, not just on a spiritual level, but a physical one too. Finally, we learn how Duke’s story of learning to conquer the waves while remaining true to his Hawaiian heritage inspired AJ to get through one of the hardest times of his life.  TW: this episode deals with the loss of a loved one and grief.

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 they hit Earth in 2015 and how scientists came to learn to use senses beyond eyesight to detect the waves. We also learn from Dr. Stavros Katsanevas about the building of a giant gravitational wave catcher called “The Interferometer.” This episode also explores how to persist in the face of doubt as we learn Wanda's tale of going blind and learning how to listen to the stars.

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.

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.

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.
