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?

In an attempt to find out, Mary Roach brings her tireless curiosity to bear on an array of contemporary and historical soul-searchers: scientists, schemers, engineers, mediums, all trying to prove (or disprove) that life goes on after we die. She begins the journey in rural India with a reincarnation researcher and ends up in a University of Virginia operating room where cardiologists have installed equipment near the ceiling to study out-of-body near-death experiences.

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.

Follow New York Times best-selling author Mary Roach - but be careful not to trip - as she weaves through personal anecdotes and everyday musings riddled with her uncanny wit and amazingly analytical eye. These essays, which found a well-deserved home within the pages of Reader's Digest as the column "My Planet," detail the inner workings of hypochondriacs, hoarders, and compulsive cheapskates. (Did we mention neurotic interior designers and professional list makers?) For Roach, humor is hidden in the most unlikely places, which means that nothing is off limits.

Dame Sue Black is an internationally renowned forensic anthropologist and human anatomist. She has lived her life eye to eye with the Grim Reaper, and she writes vividly about it in this book, which is part primer on the basics of identifying human remains, part frank memoir of a woman whose first paying job as a schoolgirl was to apprentice in a butcher shop, and part no-nonsense but deeply humane introduction to the reality of death in our lives. It is a treat for CSI junkies, murder mystery and thriller fans, and anyone seeking a clear-eyed guide to a subject that touches us all.

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).

The story of poison is the story of power. For centuries, royal families have feared the gut-roiling, vomit-inducing agony of a little something added to their food or wine by an enemy. To avoid poison, they depended on tasters, unicorn horns, and antidotes tested on condemned prisoners. Servants licked the royal family's spoons, tried on their underpants, and tested their chamber pots. Ironically, royals terrified of poison were unknowingly poisoning themselves daily with their cosmetics, medications, and filthy living conditions.

What won't we try in our quest for perfect health, beauty, and the fountain of youth? Well, just imagine a time when doctors prescribed morphine for crying infants. When liquefied gold was touted as immortality in a glass. And when strychnine - yes, that strychnine, the one used in rat poison - was dosed like Viagra. Looking back with fascination, horror, and not a little dash of dark, knowing humor, Quackery recounts the lively, at times unbelievable, history of medical misfires and malpractices. 

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

In Sweden, hundreds of refugee children fall into a state that resembles sleep for months or years at a time. In Le Roy, a town in upstate New York, teenage girls develop involuntary twitches and seizures that spread like a conta­gion. In the US Embassy in Cuba, employees experience headaches and memory loss after hearing strange noises during the night. These are only a few of the many sus­pected culture-bound psychosomatic syndromes - specific sets of symptoms that exist in a particular culture or environment - that affect people throughout the world. 

In her memoir All That Remains, internationally renowned forensic anthropologist and human anatomist Dame Sue Black recounted her life lived eye to eye with the Grim Reaper. During the course of it, she offered a primer on the basics of identifying human remains, plenty of insights into the fascinating processes of death, and a sober, compassionate understanding of its inescapable presence in our existence. Now in this book, Black builds on that memoir, taking us on a guided tour of the human skeleton and explaining how each person's life history is revealed in their bones.

By the end of 19th century, food manufacturers had rushed to embrace the rise of industrial chemistry and were knowingly selling harmful products. Unchecked by government regulation, basic safety, or even labelling requirements, they put profit before health. Then, In 1883, Dr. Harvey Washington Wiley, a chemistry professor from Purdue University, was named chief chemist of the agriculture department, and the agency began methodically investigating food and drink fraud, even conducting shocking human tests on groups of young men who came to be known as, "The Poison Squad".

A puzzling series of dental explosions beginning in the 19th century is just one of many strange tales that have long lain undiscovered in the pages of old medical journals. Award-winning medical historian Thomas Morris delivers one of the most remarkable, cringe-inducing collections of stories ever assembled.
