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.

The Ellipsis Manual is the kind of book that used to be locked away deep in a vault underground, far away from the prying eyes of those who could misuse its power.

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.

The practice of what is commonly known as hatha yoga is but one of eight branches of the body of knowledge that is yoga. Yoga is a sophisticated system of self-empowerment that is capable of harnessing and activating inner energies in such a way that your body and mind function at their optimal capacity. It is a means to create inner situations exactly the way you want them, turning you into the architect of your own joy. A yogi lives life in this expansive state, and in this transformative book Sadhguru tells the story of his own awakening.

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.

Bill Bryson once again proves himself to be an incomparable companion as he guides us through the human body - how it functions, its remarkable ability to heal itself, and (unfortunately) the ways it can fail. Full of extraordinary facts (your body made a million red blood cells since you started reading this) and irresistible Bryson-esque anecdotes, The Body will lead you to a deeper understanding of the miracle that is life in general and you in particular. As Bill Bryson writes, "We pass our existence within this wobble of flesh and yet take it almost entirely for granted."

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.

Why is Miami…Miami? What does the heartbreaking fate of the cheetah tell us about the way we raise our children? Why do Ivy League schools care so much about sports? What is the Magic Third, and what does it mean for racial harmony? In this provocative new work, Malcolm Gladwell returns for the first time in twenty-five years to the subject of social epidemics and tipping points, this time with the aim of explaining the dark side of contagious phenomena.

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.

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.

We may believe that we are the masters of our fates, but in reality, we are at the mercy of hundreds of trillions of single-celled organisms that exert control over every aspect of how our minds and bodies function. These are the diverse species of microbes that work together synergistically to communicate with each other and with every system in our bodies. You are your microbiome’s home, and it wants to take care of you, but first you have to protect it. In Gut Check, Dr. Steven Gundry reveals the emerging science proving that Hippocrates was right—all disease begins in the gut.

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.

Have you ever wondered what makes every heartbeat, every thought, and every movement possible? Meet your mitochondria—tiny but mighty organelles that are the true engines of life. These organelles are popularly known as the “powerhouses of the cell,” but new research shows that the mitochondria do more than just convert food into energy—they’re orchestrators of critical functions that keep you healthy and alive.

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.

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.

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.

Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

Dr. Mark Cucuzzella explains the simple mechanics of how our bodies have evolved and adapted to run. Despite our natural ability and our human need to run, each year more than half of all runners suffer injuries. Pain and discouragement inevitably follow. Cucuzzella's book outlines the proven, practical techniques to avoid injury and reach the goal of personal fitness and overall health.
