It was just another day on the job for 53-year-old Richard Phillips, captain of the Maersk Alabama, a United States-flagged cargo ship that was carrying, among other things, food and agricultural materials for the World Food Program. That all changed when armed Somali pirates boarded the ship.

It is autumn 1941, and a German U-boat commander and his crew set out on yet another hazardous patrol in the Battle of the Atlantic. Over the coming weeks they must brave the stormy waters of the Atlantic in their mission to seek out and destroy British supply ships. But the tide is beginning to turn against the Germans in the war for the North Atlantic. Their targets now travel in convoys, fiercely guarded by Royal Navy destroyers, and when contact is finally made the hunters rapidly become the hunted.

The pioneering advocate of wilderness preservation, John Muir (1838-1914) was influential in the creation of many national parks.

It was 13 October 1972. Uruguayan Air Force Flight 571, carrying a team of young rugby players, their families and friends, took off for the very last time. A deadly miscalculation saw F571 crash directly into the Andean mountains to devastating consequences: the body of the plane broke violently into two, its floor torn to smithereens; seats flew out of the air taking passengers with them. In the weeks that followed, the remaining people who were on board - the society of the snow - emerged to fight a dire, gruelling battle for survival.

For 13 years, 22 series and 175 shows, Richard Porter was script editor of Top Gear, from the first faltering pilot episode in 2002 until the very last show presented by Jeremy Clarkson, Richard Hammond and James May in 2015. Along the way they destroyed cars, sparked diplomatic incidents, set fire to caravans, almost killed one of the presenters, and somehow transformed Top Gear from a shabby BBC Two motoring show into an Emmy-winning, record-breaking, planet-straddling behemoth.

As a Yale School of Medicine physician, the New York Times best-selling author of Every Patient Tells a Story, and an inspiration and adviser for the hit Fox TV drama, House, M.D., Lisa Sanders has seen it all. And yet, she is often confounded by the cases she describes in her column: unexpected collections of symptoms that she and other physicians struggle to diagnose. Dr. Sanders shows how making the right diagnosis requires expertise, painstaking procedure, and sometimes a little luck.

In Underland, Robert Macfarlane takes us on a journey into the worlds beneath our feet. From the ice-blue depths of Greenland's glaciers to the underground networks by which trees communicate, from Bronze Age burial chambers to the rock art of remote Arctic sea caves, this is a deep-time voyage into the planet's past and future.

Episodes are ...

The world today is undergoing the most rapid environmental transformation in human history—from climate change to deforestation. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are closely studying trees and their biology to understand how and why trees function individually and collectively in the ways they do. In Twelve Trees, Daniel Lewis, curator and historian at one of the world’s most renowned research libraries, travels the world to learn about these trees in their habitats.

On September 11, 1999, humanity made a monumental discovery in the vastness of space. Scientists uncovered an asteroid of immense scientific importance—a colossal celestial entity. As massive as an aircraft carrier and towering as high as the iconic Empire State Building, this cosmic titan was later named Bennu. Remarkable for much more than its size, Bennu belonged to a rare breed of asteroids capable of revealing the essence of life itself. But just as Bennu became a beacon of promise, researchers identified a grave danger.

From the New York Times bestselling author of Midnight in Chernobyl comes the definitive, dramatic, minute-by-minute story of the Challenger disaster, based on fascinating in-depth reporting and new archival research—a riveting history that flows like a thriller.

The father of cognitive neuroscience and author of Human offers a provocative argument against the common belief that our lives are wholly determined by physical processes and we are therefore not responsible for our actions.

In his groundbreaking book The Biology of Belief, Dr. Bruce Lipton outlined the evidence that our thoughts are just as important as our genes in controlling our health and evolution. As the emerging science of epigenetics shows, our beliefs and choices can control our biology down to a cellular level. According to Dr. Lipton, this startling scientific insight suggests a major evolutionary shift for the human species is on the horizon.

Raging ambition. Towering egos. Competition under a veneer of courtesy. Heroic effort combined with plagiarism, theft, exaggeration, and fraud. This was the state of bird study in eastern North America during the early 1800s, as a handful of intrepid men raced to find the last few birds that were still unknown to science. The most famous name in the bird world was John James Audubon, who painted spectacular portraits of birds. But although his images were beautiful, creating art was not his main goal. Instead, he aimed to illustrate (and write about) as many different species as possible.

Why are some people so quick to recover from a setback while others wallow in despair? Why are some people so highly attuned to others that they seem psychic, while other people put both feet in it over and over again? Why are some people always up and others always down? In this hotly anticipated book, award-winning, pioneering neuroscientist Richard J. Davidson answers these questions by offering an entirely new model of our emotions - their origins, their power, and their malleability.

We've all seen the happiness on the face of a child while playing in the school yard. Or the blissful abandon of a golden retriever racing across a lawn. This is the joy of play. By definition, play is purposeless, all-consuming, and fun. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. We are designed by nature to flourish through play.

Jacques Ellul’s The Technological Society has become a classic in its field, laying the groundwork for all other studies of technology and society that have followed. Ellul offers a penetrating analysis of our technological civilization, showing how technology - which began innocuously enough as a servant of humankind - threatens to overthrow humanity itself in its ongoing creation of an environment that meets its own ends. No conversation about the dangers of technology and its unavoidable effects on society can begin without a careful listening of this book.

General Chuck Yeager was the greatest test pilot of them all - the first man to fly faster than the speed of sound...the World War II flying ace who shot down a Messerschmitt jet with a prop-driven P-51 Mustang...the hero who defined a certain quality that all hotshot fly-boys of the postwar era aimed to achieve: the right stuff. Now he tells his whole incredible life story with the same “wide-open, full throttle” approach that has marked his astonishing career.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.
