In our unique genomes, every one of us carries the story of our species - births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away - until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has completely upended what we thought we knew about ourselves. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story - from 100,000 years ago to the present.

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites listeners to explore and learn from the elegantly simple lives of mosses.

In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.

Drawing on 40 years of research and a treasure trove of new information, Tesla: Wizard at War provides a comprehensive view of Tesla's discoveries, which continue to influence today's military technology and diplomatic strategies. One of the world's leading Tesla experts, Marc J. Seifer, offers new insight into the brilliant scientist's particle beam weapon (aka the "Death Ray") and explores his military negotiations with pivotal historical figures - including his links to Joseph Stalin, Vannevar Bush, General Andrew McNaughton, and Franklin Delano Roosevelt.

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

Starting in November 2013 in a forest in Rwanda, where a modest spring spouts a trickle of clear, cold water, Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the Nile. He followed the river for nine months, over 4,000 miles, through six nations - Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt - to the Mediterranean coast.

Over half a century ago, John Rowlands set out by canoe into the wilds of Canada to survey land for a timber company. After paddling alone for several days, he came upon "the lake of my boyhood dreams", which he named Cache Lake because there was stored the best that the north had to offer-timber for a cabin; fish, game, and berries to live on; and the peace and contentment he felt he could not live without.

Whether you live in a mountain cabin or a city loft, plant spirits present themselves to us everywhere. Since its first edition in 1995, Plant Spirit Medicine has passed among countless audiences drawn to indigenous spirituality and all things alive and green. In this updated edition, Eliot Cowan invites us to discover the healing power of plants - not merely their physical medicinal properties, but the deeper wisdom and gifts that they offer.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

The restoration agriculture system described in this award-winning book works! It is possible for humans to produce staple foods using perennial agricultural ecosystems that actually improve the quality of the environment. This can be done on a backyard, farm, or ranch scale and is needed right now - on a global scale. Restoration Agriculture explains how we can have all of the benefits of natural, perennial ecosystems and create agricultural systems that imitate nature in form and function while still providing for our food, building, fuel, and many other needs.

Evolutionary theory has long established that humans are animals: Modern Homo sapiens are primates who share an ancestor with monkeys and other great apes. Our genome is 98 percent identical to a chimpanzee's. And yet we think of ourselves as exceptional. Are we? In this original and entertaining tour of life on Earth, Adam Rutherford explores the profound paradox of the "human animal".

The epic true story of an extreme athlete, a stray dog, and how they found each other—now a major motion picture from Lionsgate starring Mark Walhberg and Simu Liu. When you're racing 435 miles through the jungles and mountains of South America, the last thing you need is a stray dog tagging along. But that's exactly what happened to Mikael Lindnord, captain of a Swedish adventure racing team, when he threw a scruffy but dignified mongrel a meatball one afternoon.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

Bob Lazar was a brilliant young physicist that found himself employed at a top-secret facility in the middle of the desert outside Las Vegas. Under the watchful eye of the government elite, he is tasked with understanding an exotic propulsion system being used by an advanced aerospace vehicle he is told came from outer space. The stressful work and long, odd hours start to wear on Bob and he becomes concerned for his safety. He tells his wife and a couple close friends about what he's doing in the desert, and his employers find out and are furious.

Managing people is difficult wherever you work. But in the tech industry, where management is also a technical discipline, the learning curve can be brutal - especially when there are few tools, texts, and frameworks to help you. In this practical guide, author Camille Fournier (tech lead turned CTO) takes you through each stage in the journey from engineer to technical manager.

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

To live in a pristine land unchanged by man... to roam a wilderness through which few other humans have passed... to choose an idyllic site, cut trees and build a log cabin... to be a self-sufficient craftsman, making what is needed from materials available... to be not at odds with the world but content with one's own thoughts and company. Thousands have had such dreams, but Richard Proenneke lived them.

In 1968, nine sailors set off on the most daring race ever held: to single-handedly circumnavigate the globe nonstop. It was a feat that had never been accomplished and one that would forever change the face of sailing. Ten months later, only one of the nine men would cross the finish line and earn fame, wealth, and glory. For the others, the reward was madness, failure, and death. In this extraordinary book, Peter Nichols chronicles a contest of the individual against the sea, waged at a time before cell phones and electronic positioning systems.
