Best-selling author Mary Roach returns with a new adventure to the invisible realm we carry around inside. Roach takes us down the hatch on an unforgettable tour. The alimentary canal is classic Mary Roach terrain: The questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars. Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? How much can you eat before your stomach bursts?

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.

The study of sexual physiology has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, "The funniest science writer in the country", devoted the past two years to stepping behind those doors. In Bonk, Roach shows us how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.

Filled to the brim with far-out facts, this wickedly informative narrative from the author of National Geographic's popular Gory Details blog takes us on a fascinating journey through an astonishing new reality. Blending humor and journalism in the tradition of Mary Roach, acclaimed science reporter Erika Engelhaupt investigates the gross, strange, and morbid absurdities of our bodies and our universe.  

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.

Of all the things humans rely on plants for - sustenance, beauty, medicine, fragrance, flavor, fiber - surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable.

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. Best-selling 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.

Hi! I’m Seth! I was asked to describe my audiobook, Yearbook for websites and shit like that, so...here it goes!!! Yearbook is a collection of true stories that I desperately hope are just funny at worst, and life-changingly amazing at best. (I understand that it’s likely the former, which is a fancy “book” way of saying “the first one.”) I talk about my grandparents, doing stand-up comedy as a teenager, bar mitzvahs, and Jewish summer camp, and tell way more stories about doing drugs than my mother would like.

“How we interact with animals has preoccupied philosophers, poets, and naturalists for ages,” writes Susan Orlean. Since the age of six, when Orlean wrote and illustrated a book called Herbert the Near-Sighted Pigeon, she’s been drawn to stories about how we live with animals, and how they abide by us. Now, in On Animals, she examines animal-human relationships through the compelling tales she has written over the course of her celebrated career.

The Anthropocene is the current geologic age, in which humans have profoundly reshaped the planet and its biodiversity. In this remarkable symphony of essays adapted and expanded from his groundbreaking podcast, best-selling author John Green reviews different facets of the human-centered planet on a five-star scale - from the QWERTY keyboard and sunsets to Canada geese and Penguins of Madagascar.

A trailblazing account of human history, challenging our most fundamental assumptions about social evolution - from the development of agriculture and cities to the emergence of "the state", political violence, and social inequality - and revealing new possibilities for human emancipation.

A grand, devastating portrait of three generations of the Sackler family, famed for their philanthropy, whose fortune was built by Valium and whose reputation was destroyed by OxyContin. From the prize-winning and best-selling author of Say Nothing.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve. 

In Four Lost Cities, acclaimed science journalist Annalee Newitz takes listeners on an entertaining and mind-bending adventure into the deep history of urban life. Investigating across the centuries and around the world, Newitz explores the rise and fall of four ancient cities, each the center of a sophisticated civilization: the Neolithic site of Çatalhöyük in Central Turkey, the Roman vacation town of Pompeii in Italy, the medieval megacity of Angkor in Cambodia, and the indigenous metropolis Cahokia, which stood beside the Mississippi River where East St. Louis is today.
