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.

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.

In the misty Puerto Rican El Yunque rainforest, coquí frogs no larger than your thumb fill the air with their distinctive two-note song: “co-quí, co-quí.” They alternate routines—one night singing to attract potential mates, the next hunting to fuel up for tomorrow’s performance. In this episode, we follow a singer and a hunter amid the vibrant nighttime chorus.

The Huberman Lab podcast is hosted by Andrew Huberman, Ph.D., a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioral sciences at Stanford School of Medicine. The podcast discusses neuroscience and science-based tools, including how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health, as well as existing and emerging tools for measuring and changing how our nervous system works. Huberman has made numerous significant contributions to the fields of brain development, brain ...

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.

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.

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.

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.

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.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

In this first volume of his memoirs, then-newly-qualified vet James Herriot arrives in the small Yorkshire village of Darrowby, and he has no idea what to expect. How will he get on with his new boss? The local farmers? And what will the animals think?

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.

One of the greatest scientific feats of our era is the astonishing progress made in understanding biology-the intricate machinery of life-a progress to which the period we are living in right now has contributed the most.As you read these words, researchers are delving ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative products that are already changing the world.
