Today's kids have adopted sedentary lifestyles filled with television, video games, and computer screens. But more and more, studies show that children need "rough and tumble" outdoor play in order to develop their sensory, motor, and executive functions. Disturbingly, a lack of movement has been shown to lead to a number of health and cognitive difficulties, such as attention deficit/hyperactivity disorder (ADHD), emotion regulation and sensory processing issues, and aggressiveness at school recess break.

Learn a road map to healthy soil and revitalized food systems for powerfully addressing these times of challenge. This audiobook equips producers with knowledge, skills, and insights to regenerate ecosystem health and grow farm/ranch profits. Globally recognized soil advocate and agroecologist Nicole Masters delivers the solution to rewind the clock on this increasingly critical soil crisis in her first book For the Love of Soil. She argues we can no longer treat soil like dirt.

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.

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.

John T. Cacioppo's groundbreaking research topples one of the pillars of modern medicine and psychology: the focus on the individual as the unit of inquiry. By employing brain scans, monitoring blood pressure, and analyzing immune function, he demonstrates the overpowering influence of social context - a factor so strong that it can alter DNA replication.

We have never had so much information at our fingertips and yet most of us don’t know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check—because before we can tackle problems effectively, we must understand the facts.

Grunt tackles the science behind some of a soldier's most challenging adversaries - panic, exhaustion, heat, noise - and introduces us to the scientists who seek to conquer them. Mary Roach dodges hostile fire with the U.S. Marine Corps Paintball Team as part of a study on hearing loss and survivability in combat. She visits the fashion design studio of U.S. Army Natick Labs and learns why a zipper is a problem for a sniper.

Il est arrivé le 15 mai 1779 à l'École royale militaire de Brienne. Il n'a pas encore dix ans et parle à peine le français... Il va rester cinq ans dans cette école, sans la quitter un seul jour, sans revoir sa famille. Vingt ans plus tard, cet enfant sera le général Napoléon, maître de cette France ou il n'a d'abord été qu'un étranger. Quel caractère, quelle volonté, quel courage, quelle énergie, quelle imagination, quelle démesure, quelle puissance de rêve, quel sens des situations, quel génie il a fallu à l'enfant arraché à son milieu pour devenir le héros d'une nation !

A magnificently reported and soulfully crafted exploration of the human immune system - the key to health and wellness, life and death. An epic, first-of-its-kind audiobook, entwining leading-edge scientific discovery with the intimate stories of four individual lives, by the Pulitzer Prize-winning New York Times journalist.

A little over 100 years ago, East Africa was terra incognita to most whites: a land largely unmapped, sparsely settled by Europeans, and teeming with wildlife. It was the hunter-adventurer's paradise, and by the early 20th century, a small, lionhearted clan of explorers and big-game hunters began leading safaris there for money.

Regarded as one of the brightest young scientists of his generation, Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world as well as a thought experiment about the very idea of scientific knowledge itself.

As Indigenous scientist and author of Braiding Sweetgrass Robin Wall Kimmerer harvests serviceberries alongside the birds, she considers the ethic of reciprocity that lies at the heart of the gift economy. How, she asks, can we learn from Indigenous wisdom and the plant world to reimagine what we value most? Our economy is rooted in scarcity, competition, and the hoarding of resources, and we have surrendered our values to a system that actively harms what we love. Meanwhile, the serviceberry’s relationship with the natural world is an embodiment of reciprocity.

Few perspectives epitomize the sheer drama and sacrifice of combat more perfectly than those of the fighter pilots of World War II. As romanticized as any soldier in history, the World War II fighter pilot was viewed as larger than life: a dashing soul waging war amongst the clouds. In the 65-plus years since the Allied victory, stories of these pilots' heroics have never been in short supply. But what about their adversaries - the highly skilled German aviators who pushed the Allies to the very brink of defeat?

Worlds in Collision - written in a brilliant, easily understandable, and entertaining style and full to the brim with precise information-can be considered one of the most important and most challenging books in the history of science. Not without reason was this book found open on Einstein's desk after his death. For all those who have ever wondered about the evolution of the earth, the history of mankind, traditions, religions, mythology or just the world as it is today, Worlds in Collision is an absolute must-listen!

The American public's introduction to nuclear technology was manifested in destruction and death. With Hiroshima and the Cold War still ringing in our ears, our perception of all things nuclear is seen through the lens of weapons development. Nuclear power is full of mind-bending theories, deep secrets, and the misdirection of public consciousness - some deliberate, some accidental. The result of this fixation on bombs and fallout is that the development of a non-polluting, renewable energy source stands frozen in time.

Not since the atomic bomb has a technology so alarmed its inventors that they warned the world about its use. Not, that is, until the spring of 2015, when biologist Jennifer Doudna called for a worldwide moratorium on the use of the new gene-editing tool CRISPR - a revolutionary new technology that she helped create - to make heritable changes in human embryos.

Nothing in the universe is more complex than life. Throughout the skies, in oceans, and across lands, life is endlessly on the move. In its myriad forms—from cells to human beings, social structures, and ecosystems—life is open-ended, evolving, unpredictable, yet adaptive and self-sustaining. Complexity theory addresses the mysteries that animate science, philosophy, and metaphysics: how this teeming array of existence, from the infinitesimal to the infinite, is in fact a seamless living whole and what our place, as conscious beings, is within it.

Arguably the most significant scientific discovery of the new century, the mapping of the 23 pairs of chromosomes that make up the human genome raises almost as many questions as it answers - questions that will profoundly impact the way we think about disease, about longevity, and about free will. Questions that will affect the rest of your life. Matt Ridley here probes the scientific, philosophical, and moral issues arising as a result of the mapping of the genome.

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.

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.
