From an expert in pulmonary medicine, the story of our extraordinary lungs, the organ that both explains our origins and holds the keys to our future as a species.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy, and morality by virtue of our genes? What if our behavior actually makes us apes? What kind of apes are we?

Journalist Jeff Bercovici spent extensive time with professional and Olympic athletes, coaches, and doctors to find how today's sports superstars seemed to be able to defy the limits of physical aging that inevitably sideline their competitors. Through fascinating profiles and first-person anecdotes, Bercovici illuminates the science and strategies extending the careers of elite older athletes, uncovers the latest advances in fields from nutrition to brain science to virtual reality, and offers empowering insights about how the rest of us can find peak performance at any age.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

For two thousand years, cadavers have been involved in science's boldest strides and weirdest undertakings. They've tested France's first guillotines, ridden the NASA Space Shuttle, been crucified in a Parisian laboratory to test the authenticity of the Shroud of Turin, and helped solve the mystery of TWA Flight 800. For every new surgical procedure, from heart transplants to gender reassignment surgery, cadavers have been there alongside surgeons, making history in their quiet way.

Thought of as the seat of our soul, then as a mysteriously animated object, the heart is still more a mystery than it is understood. Why do most animals only get one billion beats? (And how did modern humans get to over two billion - effectively letting us live out two lives?) Why are sufferers of gingivitis more likely to have heart attacks? And what does it really feel like to touch your own heart, or to have someone else's beating inside your chest?

In the vein of Randall Munroe’s What If? and perfect for fans of Neil deGrasse Tyson’s Astrophysics for People in a Hurry, Leah Elson’s There Are No Stupid Questions … in Science covers biology, chemistry, physics, human physiology, and space—providing easy-to-understand, delightfully cheeky answers to over one hundred common questions, from the age-old, to the ridiculous, to the sublime.

An illuminating, authoritative, and in-depth examination of the fascinating science behind pain that “combines a career’s worth of expertise with a long history of pain treatment” (GQ) - from one of the internationally leading doctors in pain management.

Science is a force for good in the world—at least usually. But sometimes, when obsession gets the better of scientists, they twist a noble pursuit into something sinister. Under this spell, knowledge isn’t everything, it’s the only thing—no matter the cost. Bestselling author Sam Kean tells the true story of what happens when unfettered ambition pushes otherwise rational men and women to cross the line in the name of science, trampling ethical boundaries and often committing crimes in the process.

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.

Author Brian Switek is a charming and enthusiastic osteological raconteur. In this natural and cultural history of bone, he explains where our skeletons came from, what they do inside us, and what others can learn about us when these wondrous assemblies of mineral and protein are all we've left behind.

With its trillions of connections, the human brain is more beautiful and complex than anything we could ever build, but it’s far from perfect: our memory is unreliable; we can’t multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but.

That the average adult spends 50 to 70 percent of their day sitting is no surprise to anyone who works in an office environment. But few realize the health consequences they are suffering as a result of modernity's increasingly sedentary lifestyle, or the effects it has had on society at large. In Get Up!, health expert James A. Levine's original scientific research shows that today's chair-based world, where we no longer use our bodies as they evolved to be used, is having negativeconsequences on our health.

From blurry vision to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's a curious thing that human beings have beaten the odds as a species. After all, we're the only survivors on our branch of the tree of life. Why is it that human mothers have such a life-endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our achy, brilliant bodies in the process of evolution.

For centuries, poets and philosophers extolled the benefits of a walk in the woods: Beethoven drew inspiration from rocks and trees; Wordsworth composed while tromping over the heath; Nikola Tesla conceived the electric motor while visiting a park. Intrigued by our storied renewal in the natural world, Florence Williams sets out to uncover the science behind nature's positive effects on the brain.

An exploration, both personal and deeply reported, of how we learn to eat in today's toxic food culture. When her newborn daughter stopped eating after a medical crisis, Virginia Sole-Smith spent two years teaching her how to feel safe around food again - and in the process, realized just how many of us are struggling to do the same thing.

Stark narrates a series of outdoor adventure stories in which thrill can cross the line into mortal peril. Each death or brush with death is at once a suspense story, a cautionary tale, and a medical thriller. He describes what goes through the mind of a cross-country skier as his body temperature plummets - apathy at 91 degrees, stupor at 90 - and explores the physiology of a snowboarder trying not to panic as he consumes the tiny pocket of air trapped around his face under thousands of pounds of snow.

For almost 40 years, How to Choose the Sex of Your Baby has been the standard reference for couples trying to increase their chances of having the son or daughter they hope for. In this new edition of their classic book, Dr. Shettles and David Rorvik provide authoritative scientific studies and compelling anecdotal evidence demonstrating that the Shettles method continues to produce results unmatched by any other method. Dozens of testimonials confirm its ease of use and rate of success.

Physiological constraints confine our bodies to less than one-fifth of the earth's surface. Beyond that fraction lie the extremes. What happens when we go to them? Dr. Kenneth Kamler has spent years observing exactly what happens. A vice president of the legendary Explorers Club, he has climbed, dived, sledded, floated, and trekked through some of the most treacherous and remote regions in the world. A consultant for NASA, Yale University, and the National Geographic Society, he has explored undersea caves, crossed the frozen Antarctic wastelands, and more.

In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon's office, where she learns about the importance of cup size in Texas, to the laboratory, where she discovers the presence of environmental toxins in her own breast milk.
