Far from preparing them for fulfilling relationships, viewing an endless stream of porn videos led to unexpected symptoms. Perhaps most surprisingly, for the first time in history erectile dysfunction was becoming a significant problem for young men. This led to one of the largest informal experiments in the history of science. Tens of thousands of people have tried abstaining from sexually stimulating material in a process they call ‘rebooting’. Many of them reported startling changes, from improved concentration and elevated mood to a greater capacity for real-life intimacy. Gary Wilson has listened to the stories of those who have tried giving up internet porn and related them to an account of how the reward system of the brain interacts with its environment. And now a growing body of research in neuroscience is confirming what these pioneers have discovered for themselves – internet pornography can be seriously addictive and damaging. In Your Brain on Porn Wilson provides a concise introduction to the phenomenon of internet porn addiction that draws on both first-person accounts and the findings of cognitive neuroscience. In a voice that is generous and humane, he also offers advice for those who want to stop using internet pornography. The publication of Your Brain on Porn is a landmark in our attempts to understand, and remain balanced in, a world where addiction is big business.

    Entering a room with stainless-steel tables topped by corpses in body bags is shocking no matter how long you've prepared yourself, but a strange thing happened when Montross met her cadaver. Instead of being disgusted by her, she was utterly intrigued-intrigued by the person the woman once was, humbled by the sacrifice she had made in donating her body to science, fascinated by the strange, unsettling beauty of the human form. They called her Eve. This is the story of Montross and Eve-the student and the subject-and the surprising relationship that grew between them. Body of Work is a mesmerizing, rarely seen glimpse into the day-to-day life of a medical student-yet one that follows naturally in the footsteps of recent highly successful literary renderings of the mysteries of medicine such as Atul Gawande's Complications: A Surgeon's Notes on an Imperfect Science. Christine Montross was a poet long before she became a doctor and brings an uncommon perspective to the emotional difficulty of the first year of medical school-the dispiriting task of remaining clinical and detached while in the anatomy lab and the struggle with the line you've crossed by violating another's body once you leave it. Montross was so affected by her experience with Eve that she undertook to learn more about the history of cadavers and the study of anatomy. She visited an autopsy lab in Ireland and the University of Padua in Italy where Vesalius, a forefather of anatomy, once studied; she learned about body snatchers and grave-robbers and anatomists who practiced their work on live criminals. Her disturbing, often entertaining anecdotes enrich this exquisitely crafted memoir, endowing an eerie beauty to the world of a doctor-in-training. Body of Work is an unforgettable examination of the mysteries of the human body and a remarkable look at our relationship with both the living and the dead.

    Gut, an international bestseller, gives the alimentary canal its long-overdue moment in the spotlight. With quirky charm, rising science star Giulia Enders explains the gut’s magic, answering questions like: Why does acid reflux happen? What’s really up with gluten and lactose intolerance? How does the gut affect obesity and mood? Communication between the gut and the brain is one of the fastest-growing areas of medical research—on par with stem-cell research. Our gut reactions, we learn, are intimately connected with our physical and mental well-being. Enders’s beguiling manifesto will make you finally listen to those butterflies in your stomach: they’re trying to tell you something important.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    Why We Get Sick compels readers to reexamine the age-old attitudes toward sickness. Line drawings.

    Bloating. Cramps. Acne. Aches. Moodiness. Messiness. No wonder we call it The Curse! For many, it’s not just an inconvenience—it’s a colossal life disruption, forcing them to miss work, school, appointments, or dates.We’ve been encouraged to medicate away common period problems with birth control and ibuprofen, and just survive the mood swings as best we can.

When you learn to decode your period (or lack thereof), you’ll be able to recognize the underlying hormone imbalances causing your period problems and know how to fix them naturally with Jardim’s proven six-week protocol to resolve even the most challenging hormone imbalances and menstruation issues.Joining the ranks of books by Jolene Brighten, Sara Gottfried, and Aviva Romm, Nicole Jardim’s Fix Your Period is essential for women plagued by PMS, irregular, painful, or heavy periods, PCOS, Endometriosis, or fibroids—and for anyone who wants to take charge of her hormonal health—and regain control of her life—naturally.

    It was a profoundly transporting experience, and it inspired her to embark on a two-year global adventure to explore the nature of these remarkable beings and their complex relationship to humanity. Casey examines the career of the controversial John Lilly, the pioneer of modern dolphin studies whose work eventually led him down some very strange paths. She visits a community in Hawaii whose adherents believe dolphins are the key to spiritual enlightenment, travels to Ireland, where a dolphin named as “the world’s most loyal animal” has delighted tourists and locals for decades with his friendly antics, and consults with the world’s leading marine researchers, whose sense of wonder inspired by the dolphins they study increases the more they discover.Yet there is a dark side to our relationship with dolphins. They are the stars of a global multibillion-dollar captivity industry, whose money has fueled a sinister and lucrative trade in which dolphins are captured violently, then shipped and kept in brutal conditions. Casey’s investigation into this cruel underground takes her to the harrowing epicenter of the trade in the Solomon Islands, and to the Japanese town of Taiji, made famous by the Oscar-winning documentary The Cove, where she chronicles the annual slaughter and sale of dolphins in its narrow bay.Casey ends her narrative on the island of Crete, where millennia-old frescoes and artwork document the great Minoan civilization, a culture which lived in harmony with dolphins, and whose example shows the way to a more enlightened coexistence with the natural world.

    It could be an oddball researcher’s genius insight, a catalyzing moment in geopolitical history, a new breakthrough technology, or an unexpected but welcome side effect discovered during clinical trials. Piece together these stories, as Thomas Hager does in this remarkable, century-spanning history, and you can trace the evolution of our culture and the practice of medicine.  ​Beginning with opium, the “joy plant,” which has been used for 10,000 years, Hager tells a captivating story of medicine. His subjects include the largely forgotten female pioneer who introduced smallpox inoculation to Britain, the infamous knockout drops, the first antibiotic, which saved countless lives, the first antipsychotic, which helped empty public mental hospitals, Viagra, statins, and the new frontier of monoclonal antibodies. This is a deep, wide-ranging, and wildly entertaining book.

    It is a waste product and a commodity pricier than oil. It can save lives and transmit deadly infections. Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquity, the few tablespoons of blood discharged by 800 million women are still regarded as taboo; menstruation is perhaps the single most demonized biological event.Rose George, author of The Big Necessity, is renowned for her intrepid work on topics that are invisible but vitally important. In Nine Pints, she takes us from ancient practices of bloodletting to modern “hemovigilance” teams that track blood-borne diseases. She introduces Janet Vaughan, who set up the world’s first system of mass blood donation during the Blitz, and Arunachalam Muruganantham, known as “Menstrual Man” for his work on sanitary pads for developing countries. She probes the lucrative business of plasma transfusions, in which the U.S. is known as the “OPEC of plasma.” And she looks to the future, as researchers seek to bring synthetic blood to a hospital near you.Spanning science and politics, stories and global epidemics, Nine Pints reveals our life's blood in an entirely new light.

    In Beloved Beasts, acclaimed science journalist Michelle Nijhuis traces the movement’s history: from early battles to save charismatic species such as the American bison and bald eagle to today’s global effort to defend life on a larger scale.She describes the vital role of scientists and activists such as Aldo Leopold and Rachel Carson as well as lesser-known figures in conservation history; she reveals the origins of vital organizations like the Audubon Society and the World Wildlife Fund; she explores current efforts to protect species such as the whooping crane and the black rhinoceros; and she confronts the darker side of conservation, long shadowed by racism and colonialism.As the destruction of other species continues and the effects of climate change escalate, Beloved Beasts charts the ways conservation is becoming a movement for the protection of all species—including our own.

    Recent progress in genetic manipulations and calorie-restricted diets in laboratory animals hold forth the promise that someday science will enable us to exert total control over our own biological aging.Nearly all scientists who study the biology of aging agree that we will someday be able to substantially slow down the aging process, extending our productive, youthful lives. Dr. Aubrey de Grey is perhaps the most bullish of all such researchers. As has been reported in media outlets ranging from 60 Minutes to The New York Times, Dr. de Grey believes that the key biomedical technology required to eliminate aging-derived debilitation and death entirely--technology that would not only slow but periodically reverse age-related physiological decay, leaving us biologically young into an indefinite future--is now within reach.In Ending Aging, Dr. de Grey and his research assistant Michael Rae describe the details of this biotechnology. They explain that the aging of the human body, just like the aging of man-made machines, results from an accumulation of various types of damage.  As with man-made machines, this damage can periodically be repaired, leading to indefinite extension of the machine's fully functional lifetime, just as is routinely done with classic cars.  We already know what types of damage accumulate in the human body, and we are moving rapidly toward the comprehensive development of technologies to remove that damage.  By demystifying aging and its postponement for the nonspecialist reader, de Grey and Rae systematically dismantle the fatalist presumption that aging will forever defeat the efforts of medical science.

    Women have been giving birth for millennia, so why is it that every culture—and every generation—seems to have its own ideas about the best way to get a baby born? Among the topics that Tina Cassidy looks at are: why birth can be so difficult (blame our ability to walk on two legs, for instance), where women deliver, how the perception of midwives has changed (they were once burned as witches), the lives of some famous obstetricians, and the many ways childbirth has been deadly (lots of blame to go around). Birth is full of quirky details, startling facts, and tales both humorous and disturbing—from men disguised as women to get into delivery rooms to a news flash about a woman giving herself a C-section. From Jessica Mitford’s seminal The American Way of Death to Mary Roach’s Stiff, we’ve witnessed how millions of readers are fascinated by what happens at the end of life. Here is the riveting true story of how it begins.
