But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.

    According to this false-yet-familiar story, the divisions between men and women are in nature alone and not part of culture. Drawing on evolutionary science, psychology, neuroscience, endocrinology, and philosophy, Testosterone Rex disproves this ingrained myth and calls for a more equal society based on both sexes’ full human potential.

    Angier takes readers on a mesmerizing tour of female anatomy and physiology that explores everything from organs to orgasm, and delves into topics such as exercise, menopause, and the mysterious properties of breast milk.A self-proclaimed "scientific fantasia of womanhood." Woman ultimately challenges widely accepted Darwinian-based gender stereotypes. Angier shows how cultural biases have influenced research in evolutionary psychology (the study of the biological bases of behavior) and consequently led to dubious conclusions about "female nature." such as the idea that women are innately monogamous while men are natural philanderers.But Angier doesn't just point fingers; she offers optimistic alternatives and transcends feminist polemics with an enlightened subversiveness that makes for a joyful, fresh vision of womanhood. Woman is a seminal work that will endure as an essential read for anyone intersted in how biology affects who we are as women, as men, and as human beings.

    Can a person think herself to orgasm? Why doesn't Viagra help women-or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm-two of the most complex, delightful, and amazing scientific phenomena on earth-can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.

    is the first deep-dive investigation of a hazardous and illicit industry that has created a worldwide epidemic, ravaging communities and overwhelming and confounding government agencies that are challenged to combat it. "A whole new crop of chemicals is radically changing the recreational drug landscape," writes Ben Westhoff. "These are known as Novel Psychoactive Substances (NPS) and they include replacements for known drugs like heroin, cocaine, ecstasy, and marijuana. They are synthetic, made in a laboratory, and are much more potent than traditional drugs"--and all-too-often tragically lethal. Drugs like fentanyl, K2, and Spice--and those with arcane acronyms like 25i-NBOMe-- were all originally conceived in legitimate laboratories for proper scientific and medicinal purposes. Their formulas were then hijacked and manufactured by rogue chemists, largely in China, who change their molecular structures to stay ahead of the law, making the drugs' effects impossible to predict. Westhoff has infiltrated this shadowy world, becoming the first journalist to report from inside an illicit Chinese fentanyls lab and providing startling and original reporting on how China's vast chemical industry operates, and how the Chinese government subsidizes it. He tracks down the little-known scientists who invented these drugs and inadvertently killed thousands, as well as a mysterious drug baron who turned the law upside down in his home country of New Zealand. Poignantly, Westhoff chronicles the lives of addicted users and dealers, families of victims, law enforcement officers, and underground drug awareness organizers in the U.S. and Europe. Together they represent the shocking and riveting full anatomy of a calamity we are just beginning to understand. From its depths, as Westhoff relates, are emerging new strategies that may provide essential long-term solutions to the drug crisis that has affected so many.

    Teenage girls are taking courses of testosterone and disfiguring their bodies. Parents are undermined; experts are over-relied upon; dissenters in science and medicine are intimidated; free speech truckles under renewed attack; socialized medicine bears hidden consequences; and an intersectional era has arisen in which the desire to escape a dominant identity encourages individuals to take cover in victim groups. Every person who has ever had a skeptical thought about the sudden rush toward a non-binary future but been afraid to express it—this book is for you.

    Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    For two decades, historian Alice Dreger has led a life of extraordinary engagement, combining activist service to victims of unethical medical research with defense of scientists whose work has outraged identity politics activists. With spirit and wit, Dreger offers in Galileo’s Middle Finger an unforgettable vision of the importance of rigorous truth seeking in today’s America, where both the free press and free scholarly inquiry struggle under dire economic and political threats.This illuminating chronicle begins with Dreger’s own research into the treatment of people born intersex (once called hermaphrodites). Realization of the shocking surgical and ethical abuses conducted in the name of “normalizing” intersex children’s gender identities moved Dreger to become an internationally recognized patient rights’ activist. But even as the intersex rights movement succeeded, Dreger began to realize how some fellow progressive activists were employing lies and personal attacks to silence scientists whose data revealed uncomfortable truths about humans. In researching one such case, Dreger suddenly became the target of just these kinds of attacks.Troubled, she decided to try to understand more—to travel the country to ferret out the truth behind various controversies, to obtain a global view of the nature and costs of these battles. Galileo’s Middle Finger describes Dreger’s long and harrowing journeys between the two camps for which she felt equal empathy: social justice activists determined to win and researchers determined to put hard truths before comfort. Ultimately what emerges is a lesson about the intertwining of justice and of truth—and a lesson of the importance of responsible scholars and journalists to our fragile democracy.

    From distressed small communities in Central Appalachia to wealthy suburbs; from disparate cities to once-idyllic farm towns; it's a heartbreaking trajectory that illustrates how this national crisis has persisted for so long and become so firmly entrenched. Beginning with a single dealer who lands in a small Virginia town and sets about turning high school football stars into heroin overdose statistics, Macy endeavors to answer a grieving mother's question-why her only son died-and comes away with a harrowing story of greed and need. From the introduction of OxyContin in 1996, Macy parses how America embraced a medical culture where overtreatment with painkillers became the norm. In some of the same distressed communities featured in her bestselling book Factory Man, the unemployed use painkillers both to numb the pain of joblessness and pay their bills, while privileged teens trade pills in cul-de-sacs, and even high school standouts fall prey to prostitution, jail, and death.Through unsparing, yet deeply human portraits of the families and first responders struggling to ameliorate this epidemic, each facet of the crisis comes into focus. In these politically fragmented times, Beth Macy shows, astonishingly, that the only thing that unites Americans across geographic and class lines is opioid drug abuse. But in a country unable to provide basic healthcare for all, Macy still finds reason to hope-and signs of the spirit and tenacity necessary in those facing addiction to build a better future for themselves and their families.

    In addition to offering a clear-eyed explanation of the root causes of this insidious and entrenched bias and laying out its effects, she suggests concrete steps we can take to cure it.

    Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins.With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come.

    They’re also fearful about opening up a dialogue. Not Orenstein. A contributing writer to the New York Times Magazine and the New York Times best-selling author of books like Cinderella Ate My Daughter, Orenstein spoke to psychologists, academics, and other experts in the field and yes, 70 young women, to offer an in-depth picture of “girls and sex” today.

    Jonathan Eig's masterful narrative revolves around four principal characters: the fiery feminist Margaret Sanger, who was a champion of birth control in her campaign for the rights of women but neglected her own children in pursuit of free love; the beautiful Katharine McCormick, who owed her fortune to her wealthy husband, the son of the founder of International Harvester and a schizophrenic; the visionary scientist Gregory Pincus, who was dismissed by Harvard in the 1930s as a result of his experimentation with in vitro fertilization but who, after he was approached by Sanger and McCormick, grew obsessed with the idea of inventing a drug that could stop ovulation; and the telegenic John Rock, a Catholic doctor from Boston who battled his own church to become an enormously effective advocate in the effort to win public approval for the drug that would be marketed by Searle as Enovid.Spanning the years from Sanger’s heady Greenwich Village days in the early twentieth century to trial tests in Puerto Rico in the 1950s to the cusp of the sexual revolution in the 1960s, this is a grand story of radical feminist politics, scientific ingenuity, establishment opposition, and, ultimately, a sea change in social attitudes. Brilliantly researched and briskly written, The Birth of the Pill is gripping social, cultural, and scientific history.

    She finds that you cannot immunize your child, or yourself, from the world.In this bold, fascinating book, Biss investigates the metaphors and myths surrounding our conception of immunity and its implications for the individual and the social body. As she hears more and more fears about vaccines, Biss researches what they mean for her own child, her immediate community, America, and the world, both historically and in the present moment. She extends a conversation with other mothers to meditations on Voltaire's Candide, Bram Stoker's Dracula, Rachel Carson's Silent Spring, Susan Sontag's AIDS and Its Metaphors, and beyond.On Immunity is a moving account of how we are all interconnected-our bodies and our fates.
