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.Read more:Jerry Coyne, Why Evolution Is TrueThis episode was produced by Amanda Aronczyk and Jad Abumrad. Radiolab was created by Jad Abumrad and is edited by Soren Wheeler.

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.In this episode, Reporter Heather Radke and Producer Matt Kielty talk to researchers who followed the butt from our ancient beginnings through millions of years of evolution, all the way to today, out to a valley in Arizona, where our butts are put to the ultimate test. Check out Heather's book Butts - A Backstory Special thanks to Michelle Legro.

Radiolab for kids is back! Is there such a 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. That story, told by zoo director David Hancocks, architect Grant Jones, and gorilla keeper Violet Sunde. Also check out:Marina Belozerskaya's book The Medici GiraffeRadiolab is produced by Jad Abumrad.

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. Learn about the storytellers, listen to music, and dig deeper into the stories you hear on Terrestrials with activities you can do at home or in the classroom on our website, Terrestrialspodcast.org.  Watch the interferometer come to life, disco style, and find even MORE original Terrestrials fun on our Youtube.

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.
