    Dozens of examples in innumeracy show us how it affects not only personal economics and travel plans, but explains mis-chosen mates, inappropriate drug-testing, and the allure of pseudo-science.

    Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since. Drawing fascinating examples from every field of biology, he paved the way for a serious re-evaluation of evolution. He also introduced the concept of self-reproducing ideas, or memes, which (seemingly) use humans exclusively for their propagation. If we are puppets, he says, at least we can try to understand our strings.

    It also had an unexpected effect on its author: Orenstein realized that talking about girls is only half the conversation. Boys are subject to the same cultural forces as girls—steeped in the same distorted media images and binary stereotypes of female sexiness and toxic masculinity—which equally affect how they navigate sexual and emotional relationships. In Boys & Sex, Peggy Orenstein dives back into the lives of young people to once again give voice to the unspoken, revealing how young men understand and negotiate the new rules of physical and emotional intimacy.Drawing on comprehensive interviews with young men, psychologists, academics, and experts in the field, Boys & Sex dissects so-called locker room talk; how the word “hilarious” robs boys of empathy; pornography as the new sex education; boys’ understanding of hookup culture and consent; and their experience as both victims and perpetrators of sexual violence. By surfacing young men’s experience in all its complexity, Orenstein is able to unravel the hidden truths, hard lessons, and important realities of young male sexuality in today’s world. The result is a provocative and paradigm-shifting work that offers a much-needed vision of how boys can truly move forward as better men.

    Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

    Heralded by Publishers Weekly as one of the best science books of the year, it is a provocative and deeply engaging book that elucidates the ties between a woman's experience of her vagina and her sense of self; her impulses, dreams, and courage; and her role in love and in society in completely new and revelatory ways sure to provoke impassioned conversation.A brilliant and nuanced synthesis of physiology, history, and cultural criticism, Vagina: A New Biography explores the physical, political, and spiritual implications of this startling series of new scientific breakthroughs for women and for society as a whole, from a writer whose conviction and keen intelligence have propelled her works to the tops of bestseller lists, and firmly into the realms of modern classics.

    Gould's brilliant, funny, engaging prose dissects the motivations behind those who would judge intelligence, and hence worth, by cranial size, convolutions, or score on extremely narrow tests. How did scientists decide that intelligence was unipolar and quantifiable? Why did the standard keep changing over time? Gould's answer is clear and simple: power maintains itself. European men of the 19th century, even before Darwin, saw themselves as the pinnacle of creation and sought to prove this assertion through hard measurement. When one measure was found to place members of some "inferior" group such as women or Southeast Asians over the supposedly rightful champions, it would be discarded and replaced with a new, more comfortable measure. The 20th-century obsession with numbers led to the institutionalization of IQ testing and subsequent assignment to work (and rewards) commensurate with the score, shown by Gould to be not simply misguided--for surely intelligence is multifactorial--but also regressive, creating a feedback loop rewarding the rich and powerful. The revised edition includes a scathing critique of Herrnstein and Murray's The Bell Curve, taking them to task for rehashing old arguments to exploit a new political wave of uncaring belt tightening. It might not make you any smarter, but The Mismeasure of Man will certainly make you think.--Rob LightnerThis edition is revised and expanded, with a new introduction

    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.

    She invites us to explore the paradoxical union of domesticity and sexual desire, and explains what it takes to bring lust home.In her 20 years of clinical experience, Perel has treated hundreds of couples whose home lives are empty of passion. They describe relationships that are open and loving, yet sexually dull. What is going on?In this explosively original book, Perel explains that our cultural penchant for equality, togetherness, and absolute candor is antithetical to erotic desire for both men and women. Sexual excitement doesn't always play by the rules of good citizenship. It is politically incorrect. It thrives on power plays, unfair advantages, and the space between self and other. More exciting, playful, even poetic sex is possible, but first we must kick egalitarian ideals and emotional housekeeping out of our bedrooms.While Mating in Captivity shows why the domestic realm can feel like a cage, Perel's take on bedroom dynamics promises to liberate, enchant, and provoke. Flinging the doors open on erotic life and domesticity, she invites us to put the "X" back in sex.©2006 Esther Perel (P)2006 HarperCollins Publishers

    When Dr Ben Goldacre saw someone on daytime TV dipping her feet in an 'Aqua Detox' footbath, releasing her toxins into the water, turning it brown, he thought he'd try the same at home. 'Like some kind of Johnny Ball cum Witchfinder General', using his girlfriend's Barbie doll, he gently passed an electrical current through the warm salt water. It turned brown. In his words: 'before my very eyes, the world's first Detox Barbie was sat, with her feet in a pool of brown sludge, purged of a weekend's immorality.' Dr Ben Goldacre is the author of the Bad Science column in the Guardian. His book is about all the 'bad science' we are constantly bombarded with in the media and in advertising. At a time when science is used to prove everything and nothing, everyone has their own 'bad science' moments from the useless pie-chart on the back of cereal packets to the use of the word 'visibly' in cosmetics ads.

    As swiftly as it came, it disappeared, leaving no trace. Over the four decades since, Ebola has emerged sporadically, each time to devastating effect. It can kill up to 90 percent of its victims. In between these outbreaks, it is untraceable, hiding deep in the jungle. The search is on to find Ebola’s elusive host animal. And until we find it, Ebola will continue to strike. Acclaimed science writer and explorer David Quammen first came near the virus while he was traveling in the jungles of Gabon, accompanied by local men whose village had been devastated by a recent outbreak. Here he tells the story of Ebola—its past, present, and its unknowable future.Extracted from Spillover by David Quammen, updated and with additional material.

    Among those included are the woman who had blood tests done because she was convinced that "not wanting sex" was a sign of serious illness, and the man who grew up in an evangelical household and did everything "right," only to realize after marriage that his experience of sexuality had never been the same as that of others. Also represented are disabled aces, aces of color, non-gender-conforming aces questioning whether their asexuality is a reaction against stereotypes, and aces who don't want romantic relationships asking how our society can make room for them.

    Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, skewers the enduring myth that the pursuit of beauty is a learned behavior.Etcoff puts forth that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism, but instead is in our biology. It's an essential and ineradicable part of human nature that is revered and ferociously pursued in nearly every civilizatoin--and for good reason. Those features to which we are most attracted are often signals of fertility and fecundity. When seen in the context of a Darwinian struggle for survival, our sometimes extreme attempts to attain beauty--both to become beautiful ourselves and to acquire an attractive partner--become understandable. Moreover, if we come to understand how the desire for beauty is innate, then we can begin to work in our interests, and not soley for the interests of our genetic tendencies.
