In 40 years, Earth's population will reach 10 billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups - Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin.

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

Cette série réalisée il y a plusieurs années à Radio Canada International était intitulée: Les grandes familles Amérindiennes d’Amérique du Nord. Aujourd’hui, la langue et les usages ont évolué et on ne parle plus d’Amérindiens mais d’Autochtones, de Premières nations, d’Inuit et de Métis. Cette série de chroniques avec Serge Bouchard, anthropologue et spécialiste des peuples autochtones, nous emmène à la découverte des grandes familles autochtones d’Amérique du Nord.

Dieu existe-t-il ? Comment l'Univers a-t-il commencé ? Y a-t-il de la vie intelligente ailleurs ? Peut-on prévoir l'avenir ? Qu'y a-t-il à l'intérieur d'un trou noir ? Peut-on voyager dans le temps ? L'espèce humaine pourra-t-elle survivre sur la Terre ? Faut-il coloniser l'espace ? Serons-nous dépassés par l'intelligence artificielle ? Que nous réserve l'avenir ? Telles sont quelques-unes des grandes questions que Stephen Hawking éclaire dans ce livre audio auquel il a travaillé jusqu'à sa mort.

What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed that it did - and in doing so, put at risk everything we know about the fundamental laws of the universe. Leonard Susskind and Gerard 't Hooft realized the threat and responded with a counterattack that changed the course of physics.

Drs. Brock and Fernette Eide use their impressive backgrounds in neurology and education to debunk the standard deficit-based approach to dyslexia. People typically define "dyslexia" as a reading and spelling disorder. But through published research studies, clinical observations, and interviews with dyslexic individuals, the Eides prove that these challenges are not dyslexia's main features but are instead trade-offs resulting from a different pattern of brain organization and information processing that has powerful advantages.

What is consciousness? Why are we here? Where did it all come from - the laws of nature, the stars, the universe? Humans have been asking these questions forever, but science hasn't succeeded in providing many answers - until now. In The Grand Biocentric Design, Robert Lanza, one of Time magazine's "100 Most Influential People", is joined by theoretical physicist Matej Pavšic and astronomer Bob Berman to shed light on the big picture that has long eluded philosophers and scientists alike.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

New hope for those suffering from conditions like depression, anxiety, bipolar disorder, addictions, PTSD, ADHD, and more. Though incidence of these conditions is skyrocketing, for the past four decades standard treatment hasn’t much changed, and success rates in treating them have barely improved, either. Meanwhile, the stigma of the “mental illness” label - damaging and devastating on its own - can often prevent sufferers from getting the help they need. Brain specialist and best-selling author Dr. Daniel Amen aims to change all that.

Quantum theory is weird. As Niels Bohr said, if you aren’t shocked by quantum theory, you don’t really understand it. For most people, quantum theory is synonymous with mysterious, impenetrable science. And in fact for many years it was equally baffling for scientists themselves. In this tour de force of science history, Manjit Kumar gives a dramatic and superbly written account of this fundamental scientific revolution.

This book will explore whether we can successfully align our politics with climate science and the conditions under which it may be possible to act boldly. Canada’s WWII experience, Klein contends, provides a reminder that we have mobilized in common cause and retooled our economy in a few short years.

A groundbreaking guide to the surprising source of good health. Genetics and lifestyle are thought to be the two most important determinants of good health. But that is not the whole story. We have a second genome, our gut bacteria, that sets the dial on our bodies. Unlike our DNA, we can influence the gut bacteria, or microbiota, to optimize all aspects of our health. In The Good Gut, noted Stanford researchers Justin and Erica Sonnenburg investigate how the trillions of microbes that reside in our gastrointestinal tract help define us.

It’s become common to tell kids that they’re going to die from climate change. We are constantly bombarded by doomsday headlines that tell us the soil won’t be able to support crops, fish will vanish from our oceans, and that we should reconsider having children.

The United States spends an excess $1.5 trillion annually on health care compared to other wealthy countries—yet the amount of time that Americans live in good health ranks a lowly 68th in the world. At the heart of the problem is Big Pharma, which funds most clinical trials and therefore controls the research agenda, withholds the real data from those trials as corporate secrets, and shapes most of the information relied upon by health care professionals.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.

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."

Ancient Aliens explores the controversial theory that extraterrestrials have visited Earth for millions of years. From the age of the dinosaurs to ancient Egypt, from early cave drawings to continued mass sightings in the US, each episode in this hit HISTORY series gives historic depth to the questions, speculations, provocative controversies, first-hand accounts and grounded theories surrounding this age-old debate. Did intelligent beings from outer space visit Earth thousands of years ago?

One grey dismal day, Janine Marsh was on a trip to northern France to pick up some cheap wine. She returned to England a few hours later having put in an offer on a rundown old barn in the rural Seven Valleys area of Pas de Calais. This was not something she'd expected or planned for. Janine eventually gave up her job in London to move with her husband to live the good life in France. Or so she hoped. While getting to grips with the locals and la vie Française, and renovating her dilapidated new house, a building lacking the comforts of mains drainage, heating, or proper rooms.

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.
