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.

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.

The most fatal virus known to science, rabies kills nearly 100 percent of its victims once the infection takes root in the brain. From Greek myths to zombie flicks, from the laboratory heroics of Louis Pasteur to the contemporary search for a lifesaving treatment, Rabid is a fresh, fascinating, and often wildly entertaining look at one of mankind’s oldest and most fearsome foes.

Gut Reactions by chemist Simon Quellen Field shows us how our bodies react to food and the environment, and how our brain affects what and how much we eat, and in turn, is affected by what we eat. It shows why some diets work for some people but not for others, based on genetics, previous weight history, brain chemistry, environmental cues, and social pressures. It explores how dozens of hormones affect hunger and satiety and interact with the brain and the gut to regulate feeding behavior.

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.

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.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

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.

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

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.

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.

Coyote America is both an environmental and a deep natural history of the coyote. It traces both the five-million-year-long biological story of an animal that has become the "wolf" in our backyards and its cultural evolution from a preeminent spot in Native American religions to the hapless foil of the Road Runner. A deeply American tale, the story of the coyote in the American West and beyond is a sort of Manifest Destiny in reverse.

A revolutionary approach to the techniques of working with horses, by a renowned instructor. In Horses Never Lie, renowned horse trainer Mark Rashid challenges the conventional wisdom of "alpha leadership" and teaches the listener to become a "passive leader" - a counterpart to the kind of horse other members of a herd choose to associate with and to follow. Applying Rashid’s principles and techniques helps cultivate horse personalities that are responsive and dependable regardless of the rider.

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.

A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century. In 2013, Lee Berger, a National Geographic explorer-in-residence, heard of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators - men and women small and adventurous enough to be able to squeeze through eight-inch tunnels to reach a sunless cave forty feet underground. It worked.

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.

I hate every wave of the ocean', the seasick Charles Darwin wrote to his family during his five-year voyage on the H.M.S. Beagle. It was this world-wide journey, however, that launched the scientists career.

In A Good Horse Is Never a Bad Color, Mark Rashid continues to share his talent for training horses through communication rather than force. Rashid uses humorous, feel-good stories to relate his techniques of teaching horses by examining their view of the world. This book is a must-have for compassionate horse trainers and owners. Tales of Arabs, appaloosas, and paints - mistrusted and mistreated because of their breed - will give listeners a new perspective on these breeds and others.
