This pioneering account sets out to understand the structure of the human brain - the place where mind meets matter. Until recently, the left hemisphere of our brain has been seen as the "rational" side, the superior partner to the right. But is this distinction true? Drawing on a vast body of experimental research, Iain McGilchrist argues while our left brain makes for a wonderful servant, it is a very poor master.

EMS 20/20 is podcast hosted by two experienced Paramedics. Spencer Oliver and Christopher Pfingsten discuss real calls run by real responders and pull out the lessons you won't find in a text book. This podcast is aimed at Paramedic students, seasoned Paramedics looking to refresh, or any one interested in a deeper dive into pre-hospital health care.

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.

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.

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.

Now settled into the sleepy Yorkshire village of Darrowby, and married to Helen the farmer's daughter, James Herriot thinks he's finally got himself sorted. But life as a vet in the 1930s was never going to be easy. Quite aside from his unpredictable colleagues, brothers Siegfried and Tristan Farnon, he must contend with new-fangled medical techniques, delivering calves after far too much home-made wine, and a grudge-holding dog called Magnus who never forgets. And then, with Britain on the verge of war, James faces a decision that could separate him from Darrowby – and Helen – for ever . . .

In this illuminating book, brain scientist and horsewoman Janet Jones describes human and equine brains working together. Using plain language, she explores the differences and similarities between equine and human ways of negotiating the world. Mental abilities—like seeing, learning, fearing, trusting, and focusing—are discussed from both human and horse perspectives. Throughout, true stories of horses and handlers attempting to understand each other—sometimes successfully, sometimes not—help to illustrate the principles.

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.

Through clear-eyed essays and vibrant conversations, infused with data and poetry, Ayana Elizabeth Johnson guides us through solutions and possibilities at the nexus of science, policy, culture, and justice. Visionary farmers and financiers, architects and advocates, help us conjure a flourishing future, one worth the effort it will take—from every one of us, with whatever we have to offer—to create.

We may believe that we are the masters of our fates, but in reality, we are at the mercy of hundreds of trillions of single-celled organisms that exert control over every aspect of how our minds and bodies function. These are the diverse species of microbes that work together synergistically to communicate with each other and with every system in our bodies. You are your microbiome’s home, and it wants to take care of you, but first you have to protect it. In Gut Check, Dr. Steven Gundry reveals the emerging science proving that Hippocrates was right—all disease begins in the gut.

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

In 1929 Stalin launched his policy of agricultural collectivization - in effect a second Russian Revolution - which forced millions of peasants off their land and onto collective farms. The result was a catastrophic famine, the most lethal in European history. At least five million people died between 1931 and 1933 in the USSR. But instead of sending relief, the Soviet state made use of the catastrophe to rid itself of a political problem.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

How does the brain—a three-pound wrinkly mass—give rise to intelligence and conscious experience? Was Freud right that we are all plagued by forbidden sexual desires? What is the function of emotions such as disgust, gratitude, and shame? Renowned psychologist Paul Bloom answers these questions and many more in Psych, his riveting new book about the science of the mind.

CBC Radio's Quirks and Quarks covers the quirks of the expanding universe to the quarks within a single atom... and everything in between.

In Dirt to Soil, Gabe Brown tells the story of his ranch's amazing journey and offers a wealth of innovative solutions to our most pressing and complex contemporary agricultural challenge - restoring the soil. The Brown’s Ranch model, developed over 20 years of experimentation and refinement, focuses on regenerating resources by continuously enhancing the living biology in the soil.

Stephen Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet - including climate change, the threat of nuclear war, and the development of artificial intelligence - he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history.
