It began with plutonium, the first element ever manufactured in quantity by humans. Fearing that the Germans would be the first to weaponize the atom, the United States marshaled brilliant minds and seemingly inexhaustible bodies to find a way to create a nuclear chain reaction of inconceivable explosive power. In a matter of months, the Hanford nuclear facility was built to produce and weaponize the enigmatic and deadly new material that would fuel atomic bombs.

How do you make a change in your life when the tools you used to rely on start letting you down? Whether we’re struggling with a problem, a bad habit, or life in general, we often think we need to “tough it out” or “try harder.” But when we do that, our brains double down on the patterns that got us stuck in the first place. Fortunately, the science of sensation provides the key.

In Social, renowned psychologist Matthew Lieberman explores groundbreaking research in social neuroscience, revealing that our need to connect with other people is even more fundamental, more basic, than our need for food or shelter. Because of this, our brain uses its spare time to learn about the social world-other people and our relation to them.

A belief in free will touches nearly everything that human beings value. It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion.

Surveying the 20-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics.

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.

Jeff Tarrant was fascinated by the paranormal as a child but then his training as a neuropsychologist turned him into a hardcore skeptic. If something could not be reliably and consistently demonstrated in the laboratory, then it wasn’t real. These rigid ideas were gradually worn away as he repeatedly witnessed and experienced things that simply should not be possible—telekenesis, clairvoyance, telepathy, mediumship, energy healing, and more. This book follows his journey of studying, interviewing, and testing a wide variety of mediums, psychics, and healers.

Most of us have instinctive evidence the world is ending - balmy December days, face-to-face conversation replaced with heads-to-screens zomboidism, a world at constant war, a political system in disarray. We hear some myths and lies so frequently that they feel like truths: Civilization is humankind’s greatest accomplishment. Progress is undeniable. Count your blessings. You’re lucky to be alive here and now. Civilized to Death counters the idea that progress is inherently good, arguing that the "progress" defining our age is analogous to an advancing disease.

As a graduate student exploring the rain forests of Australia, Meg Lowman realized that she couldn’t monitor her beloved leaves using any of the usual methods. So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.”

V. S. Ramachandran is at the forefront of his field - so much so that Richard Dawkins dubbed him the "Marco Polo of neuroscience". Now, in a major new work, Ramachandran sets his sights on the mystery of human uniqueness. Taking us to the frontiers of neurology, he reveals what baffling and extreme case studies can teach us about normal brain function and how it evolved.
