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.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell--and what the origin of life some four billion years ago can tell us about the process of technological innovation today.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life, supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and the humble peppercorn drove the Age of Discovery, so did coffee beans help fuel the Enlightenment and cottonseed help spark the Industrial Revolution. And from the fall of Rome to the Arab Spring, the fate of nations continues to hinge on the seeds of a Middle Eastern grass known as wheat.

From batting averages and political polls to game shows and medical research, the real-world application of statistics continues to grow by leaps and bounds. How can we catch schools that cheat on standardized tests? How does Netflix know which movies you'll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

In Mycophilia, accomplished food writer and cookbook author Eugenia Bone examines the role of fungi as exotic delicacy, curative, poison, and hallucinogen, and ultimately discovers that a greater understanding of fungi is key to facing many challenges of the 21st century.

The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system.

Emily Dickinson and Charles Darwin were born at a time when the science of studying the natural world was known as natural philosophy, a pastime for poets, priests, and schoolgirls. The world began to change in the 1830s, while Darwin was exploring the Pacific aboard the Beagle and Dickinson was a student in Amherst, Massachusetts. Poetry and science started to grow apart, and modern thinkers challenged the old orthodoxies, offering thrilling new perspectives that suddenly felt radical—and too dangerous for women.

For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems.

Sailing by yourself, out of sight of land, can be invigorating and terrifying, compelling and tedious—and sometimes all of the above in one morning. But it is also a wide expanse of time in which to think. Sailing Alone tells the story of some of the remarkable people who, over the last four centuries, have spent weeks and months, moving slowly over the world's largest laboratory: a capricious and startling place in which to observe oneself, the weather, the stars, and countless sea creatures, from the tiniest to the most massive and threatening.

As early as 1530, reports of El Dorado, a city of gold in the South American interior, beckoned to European explorers. Whether there was any truth to the stories remained to be seen, but the allure of unimaginable riches was enough to ensnare dozens of would-be heroes and glory hounds in the desperate hunt. Among them was Sir Walter Raleigh: ambitious courtier, confidant to Queen Elizabeth, and, before long, El Dorado fanatic.
