    In the midst of all this death, a bizarre disease appeared in Europe. Eventually known as encephalitis lethargica, or sleeping sickness, it would spread across the world, leaving millions dead or locked in institutions. Then, in 1927, it would disappear as suddenly as it had arrived-or so the doctors at first thought. Asleep, set in 1920s and '30s New York, follows a group of neurologists through hospitals and insane asylums as they try to solve this worldwide epidemic. The symptoms could include not only unending sleep but dangerous insomnia, facial tics, catatonia, Parkinson's, and even violent insanity. Molly Caldwell Crosby, acclaimed author of The American Plague, explores the frightening history of this forgotten disease- and details the frantic effort to conquer it before it strikes again.

    But I was getting there. I wanted the world to know that all of this pain I had been feeling…that it was related to my vagina. Thus, Vagina Problems was born. It was a cutesy name. It was my way of taking this pain and saying, “Whatever. I’m here. I have it. It sucks. Let’s talk about it.”In April 2014, Deputy Editorial Director at BuzzFeed Lara Parker opened up to the world in an article on the website: she suffers from endometriosis. And beyond that? She let the whole world know that she wasn’t having any sex, as sex was excruciatingly painful. Less than a year before, she received not only the diagnosis of endometriosis, but also a diagnosis of pelvic floor dysfunction, vulvodynia, vaginismus, and vulvar vestibulitis. Combined, these debilitating conditions have wreaked havoc on her life, causing excruciating pain throughout her body since she was fourteen years old. These are her Vagina Problems. It was five years before Lara learned what was happening to her body. Five years of doctors insisting she just had “bad period cramps,” or implying her pain was psychological. Shamed and stigmatized, Lara fought back against a medical community biased against women and discovered that the ignorance of many doctors about women’s anatomy was damaging more than just her own life. One in ten women have endometriosis and it takes an average of seven years before they receive an accurate diagnosis—or any relief from this incurable illness’ chronic pain. With candid revelations about her vaginal physical therapy, dating as a straight woman without penetrative sex, coping with painful seizures while at the office, diet and wardrobe malfunctions when your vagina hurts all the time, and the depression and anxiety of feeling unloved, Lara tackles it all in Vagina Problems: Endometriosis, Painful Sex, and Other Taboo Topics with courage, wit, love, and a determination to live her best life."

    They aren't sexually attracted to anyone, and they consider it a sexual orientation—like gay, straight, or bisexual.Asexuality is the invisible orientation. Most people believe that "everyone" wants sex, that "everyone" understands what it means to be attracted to other people, and that "everyone" wants to date and mate. But that's where asexual people are left out—they don't find other people sexually attractive, and if and when they say so, they are very rarely treated as though that's okay.When an asexual person comes out, alarming reactions regularly follow; loved ones fear that an asexual person is sick, or psychologically warped, or suffering from abuse. Critics confront asexual people with accusations of following a fad, hiding homosexuality, or making excuses for romantic failures. And all of this contributes to a discouraging master narrative: there is no such thing as "asexual." Being an asexual person is a lie or an illness, and it needs to be fixed.In The Invisible Orientation, Julie Sondra Decker outlines what asexuality is, counters misconceptions, provides resources, and puts asexual people's experiences in context as they move through a very sexualized world. It includes information for asexual people to help understand their orientation and what it means for their relationships, as well as tips and facts for those who want to understand their asexual friends and loved ones.

    It’s almost as much fun, and needs less energy.” — Peter Macinnis, author of 100 Discoveries: The Greatest Breakthroughs in History "How Sex Works manages to inject science writing with the prurient thrill of a gossip rag." —O magazineMedical maverick and New York Times bestselling author of Survival of the Sickest Dr. Sharon Moalem presents an insightful and engaging voyage through the surprising history and evolution of sexual reproduction.

     For his groundbreaking sexual research, Alfred Kinsey and his team interviewed 18,000 people, relying on them to honestly report their most intimate experiences. Using the Internet, the neuroscientists Ogas and Gaddam quietly observed the raw sexual behaviors of half a billion people. By combining their observations with neuroscience and animal research, these two young neuroscientists finally answer the long-disputed question: what do people really like? Ogas and Gaddam's findings are transforming the way scientists and therapists think about sexual desire. In their startling book, Ogas and Gaddam analyze a "billion wicked thoughts" on the Internet: a billion Web searches, a million individual search histories, a million erotic stories, a half-million erotic videos, a million Web sites, millions of online personal ads, and many other enormous sources of sexual data in order to understand the true differences between male and female desires, including: ?Men and women have hardwired sexual cues analogous to our hardwired tastes-there are sexual versions of sweet, sour, salty, savory, and bitter. But men and women are wired with different sets of cues. ?The male sexual brain resembles a reckless hunter, while the female sexual brain resembles a cautious detective agency. ?Men form their sexual interests during adolescence and rarely change. Women's sexual interests are plastic and change frequently. ?The male sexual brain is an "or gate": A single stimulus can arouse it. The female sexual brain is an "and gate": It requires many simultaneous stimuli to arouse it. ?When it comes to sexual arousal, men prefer overweight women to underweight women, and a significant number of men seek out erotic images of women in their 40s, 50s, and 60s. ?Women enjoy writing and sharing erotic stories with other women. The fastest growing genre of erotic stories for women are stories about two heterosexual men having sex. ?Though the male sexual brain is much more different from the female sexual brain than is commonly believed, the sexual brain of gay men is virtually identical to that of straight men. Featuring cutting-edge, jaw-dropping science, this wildly entertaining and controversial book helps readers understand their partner's sexual desires with a depth of knowledge unavailable from any other source. Its fascinating and occasionally disturbing findings will rock our modern understanding of sexuality, just as Kinsey's reports did sixty years ago.

    In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. In the tradition of Jared Diamond’s Guns, Germs, and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

    This was the world of medicine when Thomas Dent Mütter began his trailblazing career as a plastic surgeon in Philadelphia during the middle of the nineteenth century.Although he died at just forty-eight, Mütter was an audacious medical innovator who pioneered the use of ether as anesthesia, the sterilization of surgical tools, and a compassion-based vision for helping the severely deformed, which clashed spectacularly with the sentiments of his time.   Brilliant, outspoken, and brazenly handsome, Mütter was flamboyant in every aspect of his life. He wore pink silk suits to perform surgery, added an umlaut to his last name just because he could, and amassed an immense collection of medical oddities that would later form the basis of Philadelphia’s Mütter Museum. Cristin O’Keefe Aptowicz chronicles how Mütter’s efforts helped establish Philadelphia as a global mecca for medical innovation—despite intense resistance from his numerous rivals.
