Terrestrials

Amy Ray (whose music you might know from the Indigo Girls) was on a walk in the Georgia woods with her seven dogs when she passed a tree branch and saw hundreds of tiny, white, fluffy creatures doing a synchronized stadium wave. She was mesmerized. Turns out, she was looking at woolly aphids - small, defenseless bugs who have somehow figured out how to survive everything the forest throws at them. Resident Bug Correspondent Dr. Sammy Ramsey explains how: from the army of ants fighting their battles, to their power to clone themselves over and over, to their sap-eating ways that make plants scream chemical SOS signals through the air! What starts as a story about a fuzzy bug turns into one about a secret harmony running through the whole forest. Plus, we try aphid poop honey! Special thanks to Amy Ray and Ozie, and to Dr. Sammy Ramsey, whose new documentary Secrets of the Bees from National Geographic is out now. Terrestrials was created by Lulu Miller with WNYC studios.

As one of the most famous cellists of all time, Yo-Yo Ma has spent a lot of time playing music inside. But a few years ago, he decided to take the cello out of the fancy concert halls and into nature, bringing our very own Producerbud Ana along for the ride! That brings us to humpback whales. Like Yo-Yo, humpbacks are musical. They communicate through melodies, clicks, grunts, whispers, and bellows. Human beings still don’t fully know what the whales are saying to each other, but for Yo-Yo it sounds just like cello music. So, he had a wild idea: What if he tried to communicate with whales using his cello? On a very windy December day, Producerbud Ana and Yo-Yo travel to Hawai'i and meet up with hula master, Snowbird Bento, who explains how she uses music to connect with the natural world. Then, they all board a legendary canoe called Hōkūleʻa with local fishermen, seafaring captains, and marine biologists, and Yo-Yo plays his cello, hoping the whales will hear the vibrations and maybe... respond? To find out what happens next, sit back, relax, and join Ana and Yo-Yo on an aquatic adventure. This was an episode from Our Common Nature, a seven-episode podcast series of Yo-Yo Ma’s musical journey around the country to places where people have deep connections to the Earth.

What do loons have to do with courage and community? In January, we received a letter from two sisters in Minnesota - Jude and Mo. They wrote to us because their city was experiencing a lot of unrest, with immigration agents arresting members of their community and protests ringing loud in the streets as people tried to protect their neighbors. And in the middle of it all, an unexpected symbol began appearing on storefronts, stickers, and even as tattoos: the black and white, migrating waterbird known as the loon. Jude and Mo were curious: why are loons a good symbol of standing strong in the face of adversity? Loon expert Dr. Walter Piper breaks down the incredible biology of the loon and helps us decode their mysterious calls; storyteller Hope Flanagan brings us Ojibwe tales of how the loon got its famous red eyes; and biologist Dr. Leonardo Chapa Vargas teaches us about loon migration, helping us expand our definition of home. We learn why these loud and eerie birds came to stand for something very powerful: the scrappy resilience of trying over and over again, no matter how many times you get knocked down. Huge thanks to Jude, Mo and their mom, Natalie, for writing in about loons. Reminder that you can also write in about any creature you’d like to see an episode on! Email us at terrestrials@wnyc.org.

How rested would you feel if you took 10,000 naps a day? Chinstrap Penguins in Antarctica spend their days taking MICRONAPS, each around 4 seconds long. To learn why, Lulu meets one (played by Songbud Alan), who explains how micronaps help them conserve energy and protect their babies from “sky pirates”! Then, in a badgermania, penguin scientists Dr. Eric Wagner and Dr. Dee Boersma answer your questions! Why are penguins black-and-white? Why is their poop pink? What might they dream about? And we learn that what may look like laziness… turns out to be an evolutionary superpower. Don’t sleep on these articles, maybe read them before your next nap: Read about chinstrap penguin naps here, and here, and here. Learn why penguin poop is pink and how it may be helping cool the climate! Read about how neurons help flush waste out of the brain during sleep.

Holes are full of a whole lot of nothin'. Pure, hollow emptiness. At least that’s what Songbud Alan thought before he fell down a rabbit hole of, well, HOLES! In honor of Groundhog Day, he takes Lulu to a fossil-filled pit behind a Chick-fil-A to dig up 66-million-year-old treasure, and deep down to an underwater hole where blobs of colorful microbes reveal a time when Earth’s days were only 6 hours long. We discover eyeless cave fish, fall into a sinkhole of Corvettes, and go house hunting for the perfect animal hole to cozy up in... which leads us to one of the coziest holes of all: a groundhog’s burrow.

Where do animals come from? That's something people have been trying to explain for thousands of years. And for a while, scientists and philosophers believed that any ol' person could create creatures if they just had the right recipe. A touch of sand, maybe a drop of blood and POOF: you could create life. That idea was believed to be true for generations until one brave scientist decided to look more closely at an unlikely bug and change the course of science forever. Lulu calls up our biology correspondent, Dr. Avir Mitra, to solve this ancient mystery. Terrestrials was created by Lulu Miller with WNYC.

Sloths are the slowest mammals on Earth. How can a creature that moves so slowly survive in a world that moves so fast? Zoologist Lucy Cooke helps us rethink everything we know about sloths and their slowness. We follow a sloth named Nacho from a rainforest to a nightclub, trek deep into mangrove swamps to find a rare pygmy sloth and uncover the secret that allows sloths to evade even the deadliest predators. Hint: it has to do with a special kind of invisibility. For more, check out Lucy’s A Little Book of Sloth and her sloth calendar! Terrestrials was created by Lulu Miller with WNYC.

What is a rainbow? An optical illusion? Or a thing out there in the world? For centuries, cultures around the world believed that rainbows were bridges - pathways to gods and to the afterlife. Then in 1665, during a plague, a young Isaac Newton made a discovery that changed everything : sunlight is made of many colors. He counted 7. But artists, poets and curious children weren’t convinced. How could a rainbow only have seven colors? Their skepticism led to a far stranger discovery that would revolutionize how we understand the universe. - In the end, we learn that rainbows are kind of a bridge - between our outer and inner worlds. Science writer Philip Ball helps us follow the rainbow’s story, plus Songbud and the Youth Pride Chorus of New York City turn it all into a magical musical. To learn more about the history of color, read Dr. Ball’s book Bright Earth. Special thanks to Philip Ball, the Youth Pride Chorus of NYC, Nicholas Sienkiewicz and Rashad Chambers.

This Halloween, we’re going to the dark side. Deep in the darkest tropical forests, some of the world’s most elusive bats hang upside down in their winged sleeping bags. On a quest to find one of these flying mammals, Producerbud Ana ventures into a Puerto Rican forest and the back corridors of the American Museum of Natural History with Dr. Angelo Soto-Centeno. Why? Because while they may be scary and look kinda like Dracula, with their sharp fangs and beady eyes, these bats hold something crucial for humanity - the ability to repair entire ecosystems after some of the most destructive hurricanes ever.

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 country and then… everyone forgot about them. Until one day, a third grader from Indiana stumbled on a tree with a strange plaque: "Moon Tree." This discovery set off a cascading search for all the trees that visited the moon across the United States. Science writer, and our very own factchecker, Natalie Middleton tells us the tale. We’re holding a Moon Tree contest! Send us a drawing of what you imagine a Moon Tree to look like. Submit here.

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 beavers out of planes into the mountains. And finally head to California where we discover how one beaver family saved acres of land from burning.

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 blood became indispensable for modern medicine.

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 some reason it always felt gross to her. So as an extreme challenge, we’re taking a closer look at clam chowder to see if it can become wondrous. Ana and Alan break down each ingredient - milk, potatoes, and finally clams - with a concoction of stories and guests. Then, if she’s convinced of clam chowder’s magic, Lulu will try clam chowder for the first time in her life. You can watch a full video taping of this episode here. Listen if you love clam chowder, but especially if you’re a chowda doubta. Special thanks to scientist Rachel Hutchison from the Woods Hole Oceanographic Sea Grant for all of her clam knowledge and WBUR’s CitySpace for hosting this event. Hope to see you in New York City!

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 flexible they can eat almost anything and live everywhere from open prairies to city streets, where they lurk unseen like urban ghosts. Conservation scientist Christine Willkinson, or scrappy naturalist, tells us why a coyote’s scrappiness is its greatest superpower. In a world that rewards specialists, coyotes make a case for generalists - the ones not spectacular at any one thing, but just okay at everything. Plus, to find these ghosts in her own city, Lulu goes on an urban coyote hunt.

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, disrupting not only their sleep but their precious ecosystems. Listen as Ana explores how different islands can view these frogs so differently, and how, despite all of our human efforts, they won’t stop singing. Special thanks to evolutionary biologist Ana Longo and professor Noelani Puniwai for telling us about coquí frogs. Watch a coquí frog perform its call. Listen to Puerto Rican sleep sounds.
