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.

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.

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?

What’s to be done about a jaywalking moose? A bear caught breaking and entering? A murderous tree? Three hundred years ago, animals that broke the law would be assigned legal representation and put on trial. These days, as New York Times best-selling author Mary Roach discovers, the answers are best found not in jurisprudence but in science: the curious science of human-wildlife conflict, a discipline at the crossroads of human behavior and wildlife biology. 

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.  

Just two months before the September 11 terrorist attacks, Dr. Judy Melinek began her training as a New York City forensic pathologist. With her husband and their toddler holding down the home front, Judy threw herself into the fascinating world of death investigation-performing autopsies, investigating death scenes, and counseling grieving relatives. Working Stiff chronicles Judy's two years of training, taking listeners behind the police tape of some of the most harrowing deaths in the Big Apple.

Fascinated by our pervasive terror of dead bodies, mortician Caitlin Doughty set out to discover how other cultures care for their dead. In rural Indonesia, she observes a man clean and dress his grandfather's mummified body. Grandpa's mummy has lived in the family home for two years, where the family has maintained a warm and respectful relationship. She meets Bolivian natitas (cigarette-smoking, wish-granting human skulls) and introduces us to a Japanese kotsuage.

Most people want to avoid thinking about death, but Caitlin Doughty - a 20-something with a degree in medieval history and a flair for the macabre - took a job at a crematory, turning morbid curiosity into her life’s work. With an original voice that combines fearless curiosity and mordant wit, Caitlin tells an unusual coming-of-age story full of bizarre encounters, gallows humor, and vivid characters (both living and very dead).

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.

In Will My Cat Eat My Eyeballs?, Doughty blends her mortician’s knowledge of the body and the intriguing history behind common misconceptions about corpses to offer factual, hilarious, and candid answers to 35 distinctive questions posed by her youngest fans. In her inimitable voice, Doughty details lore and science of what happens to, and inside, our bodies after we die. Why do corpses groan? What causes bodies to turn colors during decomposition? And why do hair and nails appear longer after death?

With poignant insight and humor, Frank Vertosick, Jr., MD, describes some of the greatest challenges of his career, including a six-week-old infant with a tumor in her brain, a young man struck down in his prime by paraplegia, and a minister with a .22-caliber bullet lodged in his skull. Told through intimate portraits of Vertosick's patients and unsparing-yet-fascinatingly detailed descriptions of surgical procedures, When the Air Hits Your Brain illuminates both the mysteries of the mind and the realities of the operating room.

Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

Using the most common postmortem process as the backbone of the narrative, The Chick and the Dead takes the listener through the process of an autopsy while also describing the history and changing cultures of our relationship with the dead. The book is full of vivid insight into what happens to our bodies in the end. Each chapter considers an aspect of an autopsy alongside an aspect of Carla's own life and work and touches on some of the more controversial aspects of our feelings toward death.

The emergence of strange new diseases is a frightening problem that seems to be getting worse. In this age of speedy travel, it threatens a worldwide pandemic. We hear news reports of Ebola, SARS, AIDS, and something called Hendra killing horses and people in Australia - but those reports miss the big truth that such phenomena are part of a single pattern. The bugs that transmit these diseases share one thing: they originate in wild animals and pass to humans by a process called spillover. David Quammen tracks this subject around the world.

Bill Bryson and his family live in a Victorian parsonage in a part of England where nothing of any great significance has happened since the Romans decamped. Yet one day, he began to consider how very little he knew about the ordinary things of life as he found it in that comfortable home. To remedy this, he formed the idea of journeying about his house from room to room to “write a history of the world without leaving home.”
