After graduating from college, Jennifer isn't sure what she wants to do with her life. She is drawn to the Appalachian Trail, a 2,175-mile footpath that stretches from Georgia to Maine. Though her friends and family think she's crazy, she sets out alone to hike the trail, hoping it will give her time to think about what she wants to do next. The next four months are the most physically and emotionally challenging of her life.

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.

Factfulness: The stress-reducing habit of carrying only opinions for which you have strong supporting facts. When asked simple questions about global trends - what percentage of the world's population live in poverty; why the world's population is increasing; how many girls finish school - we systematically get the answers wrong. In Factfulness, professor of international health and global TED phenomenon Hans Rosling, together with his two longtime collaborators, Anna and Ola, offers a radical new explanation of why this happens.

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

True stories of the most extreme wild animal attacks ever documented, told and explained by Wes Larson, a wildlife biologist and animal behavior expert. Wes is joined by his brother Jeff and their mutual friend Mike, and in each episode the three pour over the details of animals attacks and explain how listeners can avoid these kinds of dangerous encounters, and learn a new appreciation for the wild things of the world

The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

You wake up and feel a tickle in your throat. Your head hurts. You’re mildly annoyed as you get the kids ready for school and dress for work yourself. Meanwhile, an epic war is being fought, just below your skin. Millions are fighting and dying for you to be able to complain as you head out the door. So what, exactly, is your immune system? In Immune, Philipp Dettmer, the brains behind the most popular science channel on YouTube, takes listeners on a journey through the fortress of the human body and its defenses.

False Alarm will convince you that everything you think about climate change is wrong. It points the way toward making the world a vastly better, if slightly warmer, place for us all.

In the winter of 1952, New England was battered by the most brutal nor’easter in years. As the weather wreaked havoc on land, the freezing Atlantic became a wind-whipped zone of peril, setting the stage for one of the most heroic rescue stories ever lived. On February 18, while the storm raged, two oil tankers, the Pendleton and the Fort Mercer, were in the same horrifying predicament. Built with “dirty steel,” and not prepared to withstand such ferocious seas, both tankers split in two, leaving the dozens of men on board utterly at the Atlantic’s mercy.

In this fascinating foray into the centuries-old relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions," say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion, and access to space. Tyson and Lang call it a "curiously complicit" alliance.

In each episode, we bring you riveting interviews with individuals who have had encounters with the elusive Sasquatch. Each one of these stories will leave you wanting more. But that's not all. We go beyond the encounters and explore the realm of Bigfoot research from a critical thinking perspective.

These dedicated individuals use hard science and rigorous methodologies to investigate the existence of this legendary creature. Through thought-provoking discussions, we aim ...

Host Jack Luna covers the worlds darkest stories, while holding you close in an itchy blanket.

Off the beaten path, following unmarked trails, we are wired to explore. More than just a need to get outside, the search for the unknown is a primal urge that has shaped the history of our species and continues to mold our behavior in ways we are only beginning to understand. In fact, the latest neuroscience suggests that exploration in any form—whether it’s trying a new restaurant, changing careers, or deciding to run a marathon—is an essential ingredient of human life. Exploration, it turns out, isn’t merely a hobby—it’s our story.

Compact Farms is a guide for anyone dreaming of starting, expanding, or perfecting a profitable farming enterprise on five acres or less. The farm plans explain how to harness an area's water supply, orientation, and geography in order to maximize efficiency and productivity while minimizing effort. Profiles of well-known farmers such as Eliot Coleman and Jean-Martin Fortier show that farming on a small scale in any region, in both urban and rural settings, can provide enough income to turn the endeavor from hobby to career.

Section 3 develops the interface and interaction between we the people and our digital consciousness reality. It derives and explains the characteristics, origins, dynamics, and function of ego, love, and free will. It derives our larger purpose. Finally, Section 3 develops the psi uncertainty principle as it explains and interrelates psi phenomena, free will, love, consciousness evolution, reality, human purpose, entropy and physics.

In May 2016, Fort McMurray, the hub of Canada's petroleum industry and America's biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event but a shocking preview of what we must prepare for in a hotter, more flammable world.

While everything appears to be collapsing around us - ecodamage, genetic engineering, virulent diseases, water shortages, global famine, wars - we can still do something about it and create a world that will work for us and for our children's children. The inspiration for Leonardo DiCaprio's feature documentary movie The 11th Hour, The Last Hours of Ancient Sunlight details what is happening to our planet, the reasons for our culture's blind behavior, and how we can fix the problem.

On a spring evening in Montana, Brian Buckbee encounters an injured baby pigeon. Heartbroken after the loss of the love of his life and increasingly isolated by a mysterious illness that overtook him while trekking through Asia, Brian is unaware that this bird—who he names Two-Step—will change his life. Brian takes in Two-Step, and more injured birds, eventually transforming his home into a madcap bird rehabilitation and rescue center. As Brian and Two-Step grow closer, an unexpected kinship forms.

But when he arrived, Sherman was in such bad shape he could barely move, and his hair was coming out in clumps. Chris decided to undertake a radical rehabilitation program designed not only to heal Sherman's body but to heal his mind as well - and so Chris decided to teach Sherman how to run.
