North Ronaldsay sheep have been roaming the shores of a Scottish isle for centuries. They outnumber people there by more than twenty to one. While most sheep graze in fields, the North Ronaldsay are a breed apart: they forage seaweed on the rocky beach. In this episode, we follow a lamb as she crosses the island’s ancient stone dyke and sees the ocean for the first time.

No running water, no car, no electricity or any of the things it powers: the internet, phone, washing machine, radio, or light bulb. Just a wooden cabin, on a smallholding, by the edge of a stand of spruce. The Way Home is a modern-day Walden - an honest and lyrical account of a remarkable life lived in nature without modern technology. Mark Boyle, author of The Moneyless Man, explores the hard-won joys of building a home with his bare hands, learning to make fire, collecting water from the stream, foraging, and fishing.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

Welcome to our voyage of discovery. In this series we’ll be travelling to many hard to reach places. Some hidden from view entirely: deep waters, high skies, the vastness of space. We’ll fly with a bee across a summer meadow all the way into her hive. Dive deep into the ocean to visit the miraculous Black Smokers. And we’ll even travel on the inside of a water molecule before it turns into a hailstone. We’re on an extraordinary audio journey of imagination – to learn something fascinating about our world and gently relax or fall asleep along the way.

Reality is not what it seems. Not fixed. Not silent. Not separate from the one who observes it. Quantum experiments reveal seams in the world… places where information appears without traveling… where outcomes wait for attention… where time behaves like something far more flexible than a river. These seams form a doorway. A narrow line where darkness gives way to light… where the familiar dissolves into the possible… where a question becomes the beginning of understanding. This book does not claim answers. It offers a key. If you have ever sensed something beneath the surface… Step closer.

From the author of Apocalyptic Planet, an unsparing, vivid, revelatory travelogue through prehistory that traces the arrival of the First People in North America 20,000 years ago and the artifacts that enable us to imagine their lives and fates. This book upends our notions of where these people came from and who they were.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed that it did - and in doing so, put at risk everything we know about the fundamental laws of the universe. Leonard Susskind and Gerard 't Hooft realized the threat and responded with a counterattack that changed the course of physics.

The Little Ice Age tells the story of the turbulent, unpredictable, and often very cold years of modern European history, how climate altered historical events, and what they mean in the context of today’s global warming.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

When she first went to sea in April of 1961, the US nuclear submarine Thresher was the most advanced submarine at sea, built specifically to hunt and kill Soviet submarines. In The Death of the USS Thresher, renowned naval and intelligence consultant Norman Polmar recounts the dramatic circumstances surrounding her implosion, which killed all 129 men onboard in history's first loss of a nuclear submarine.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

The atom, the big bang, DNA, natural selection - all are ideas that have revolutionized science; and all were dismissed out of hand when they first appeared. The surprises haven't stopped in recent years, and in At the Edge of Uncertainty, best-selling author Michael Brooks investigates the new wave of radical insights that are shaping the future of scientific discovery.

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.

In this exquisitely written book, Robert Macfarlane sets off from his Cambridge, England, home to follow the ancient tracks, holloways, drove roads, and sea paths that crisscross both the British landscape and its waters and territories beyond. The result is an immersive, enthralling exploration of the ghosts and voices that haunt old paths, of the stories our tracks keep and tell, and of pilgrimage and ritual. Told in Macfarlane’s distinctive voice, The Old Ways folds together natural history, cartography, geology, archaeology, and literature.

The author was drawn into the United States Army through ROTC, and he went through training to fly helicopters in combat over Vietnam. His experiences are notable because he flew both Huey “Slicks” and Huey “Gunships”: the former on defense as he flew troops into battle, and the latter on offense as he took the battle to the enemy. Through this book, the author relives his experiences flying and fighting, with special attention given to his and other pilots’ day-to-day lives.

Inside our heads we carry around an infinite and endlessly unfolding map of the world. Navigation is one of the most ancient neural abilities we have - older than language. In Dark and Magical Places, Christopher Kemp embarks on a journey to discover the remarkable extent of what our minds can do.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.
