This true-life wilderness survival epic recounts 17-year-old Alex Messenger's near-lethal encounter with a grizzly bear during a canoe trip in the Canadian tundra. The story follows Alex and his five companions as they paddle north through harrowing rapids and stunning terrain. Twenty-nine days into the trip, while out hiking alone, Alex is attacked by a barren-ground grizzly. Left for dead, he wakes to find that his summer adventure has become a struggle to stay alive.

Imagine a world without bees, butterflies, and flowering plants. That was Earth 125 million years ago. Turn back the clock 400 million years, and there were no trees. At 450 million years in the past, even the earliest insects had not yet developed. And looking back 500 million years, the land was devoid of life, which at that time flourished in a profusion of strange forms in the oceans. These and other major turning points are the amazing story of evolution.

Every culture is a unique answer to a fundamental question: What does it mean to be human and alive? In The Wayfinders, renowned anthropologist, winner of the prestigious Samuel Johnson Prize, and National Geographic Explorer-in-Residence Wade Davis leads us on a thrilling journey to celebrate the wisdom of the world's indigenous cultures.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

How is it possible for the disciplines of cosmology, geology, anthropology, biology, and history to fit together? These 48 lectures answer that question by weaving a single story from accounts of the past developed by a variety of scholarly disciplines. The result is a story stretching from the origins of the universe to the present day and beyond, in which human history is seen as part of the history of our Earth and biosphere, and the Earth's history, in turn, is seen as part of the history of the universe.

Where do we come from? How did our ancestors settle this planet? How did the great historic civilizations of the world develop? How does a past so shadowy that it has to be painstakingly reconstructed from fragmentary, largely unwritten records nonetheless make us who and what we are?

These 36 lectures bring you the answers that the latest scientific and archaeological research and theorizing suggest about human origins, how populations developed, and the ways in which civilizations spread throughout the globe.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

A revolutionary approach to the techniques of working with horses, by a renowned instructor. In Horses Never Lie, renowned horse trainer Mark Rashid challenges the conventional wisdom of "alpha leadership" and teaches the listener to become a "passive leader" - a counterpart to the kind of horse other members of a herd choose to associate with and to follow. Applying Rashid’s principles and techniques helps cultivate horse personalities that are responsive and dependable regardless of the rider.

Social connection is as essential for our health and happiness as a balanced diet and regular exercise. It reduces our risk of stroke, heart disease, and Alzheimer's. It enhances our creativity and adds years to our life span. Yet many of us struggle to form strong and meaningful bonds—and the problem lies not with our personalities but with a series of cognitive biases that stop us from fulfilling our social potential. In The Laws of Connection, David Robson describes the psychological barriers that lead us to keep others at a distance and offers evidence-based strategies to overcome them.

There is no one better qualified than Jared Diamond - renowned expert in the fields of physiology and evolutionary biology and award-winning author - to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

Un son, une note, une mélodie et voilà...le cerveau en effervescence. Mais pourquoi certains airs arrivent-ils à nous tirer des larmes, à nous donner la chair de poule, à nous enthousiasmer ou à nous faire danser? Journaliste scientifique aguerri, Michel Rochon nous entraîne dans une exploration fascinante du cerveau musical. Il nous révèle les plus récentes découvertes en intelligence artificielle, en neuropsychologie, en linguistique et même en mathématiques qui nous font comprendre autrement les harmonies sonores.

Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.

"I had never planned to become a savanna baboon when I grew up; instead, I had always assumed I would become a mountain gorilla," writes Robert Sapolsky in this witty and riveting chronicle of a scientist's coming-of-age in remote Africa. An exhilarating account of Sapolsky's twenty-one-year study of a troop of rambunctious baboons in Kenya, A Primate's Memoir interweaves serious scientific observations with wry commentary about the challenges and pleasures of living in the wilds of the Serengeti-for man and beast alike.

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".

Dish up the red meat, eggs, and whole milk! In this well-researched and captivating narrative, veteran food writer Nina Teicholz proves how everything we've been told about fat is wrong. For decades, Americans have cut back on red meat and dairy products full of "bad" saturated fats. We obediently complied with nutritional guidelines to eat "heart healthy" fats found in olive oil, fish, and nuts, and followed a Mediterranean diet heavy on fruits, vegetables, and grains. Yet the nation's health has declined. What is going on?

We use DNA routinely - to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. But what, exactly is DNA, the self-replicating material present in nearly all living organisms?

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.

Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.

Since it was first published in 2005, Ray Kurzweil's The Singularity Is Near and its vision of the future have been influential in spawning a worldwide movement with millions of followers, hundreds of books, major films, and thousands of articles. During the succeeding decade, many of Kurzweil's predictions about technological advancements have been borne out, and their viability has become familiar to the public through such now commonplace concepts. In this entirely new book Ray Kurzweil brings a fresh perspective to advances in the singularity.
