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.

    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.

    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.

    Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities. . . .But, Zimmer writes, "Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are--our appearance, our height, our penchants--in inconceivably subtle ways." Heredity isn't just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors--using a word that once referred to kingdoms and estates--but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer's lucid exposition and storytelling, this resounding tour de force delivers it. Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world's best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.

    From the world’s most painful hornet, to the flies that transmit deadly diseases, to millipedes that stop traffic, to the “bookworms” that devour libraries, to the Japanese beetles munching on your roses, Wicked Bugs delves into the extraordinary powers of many-legged creatures. With wit, style, and exacting research, Stewart has uncovered the most terrifying and titillating stories of bugs gone wild. It’s an A to Z of insect enemies, interspersed with sections that explore bugs with kinky sex lives (“She’s Just Not That Into You”), creatures lurking in the cupboard (“Fear No Weevil”), insects eating your tomatoes (“Gardener’s Dirty Dozen”), and phobias that feed our (sometimes) irrational responses to bugs (“Have No Fear”). Intricate and strangely beautiful etchings and drawings by Briony Morrow-Cribbs capture diabolical bugs of all shapes and sizes in this mixture of history, science, murder, and intrigue that begins—but doesn’t end—in your own backyard.

    So where is it? Well, for reasons this book makes crystal clear, that pill will never exist—but as a result of the research that’s gone into it, scientists in the last few years have learned more about how women’s sexuality works than we ever thought possible, and Come as You Are explains it all.The first lesson in this essential, transformative book by Dr. Emily Nagoski is that every woman has her own unique sexuality, like a fingerprint, and that women vary more than men in our anatomy, our sexual response mechanisms, and the way our bodies respond to the sexual world. So we never need to judge ourselves based on others’ experiences. Because women vary, and that’s normal.Second lesson: sex happens in a context. And all the complications of everyday life influence the context surrounding a woman’s arousal, desire, and orgasm. Cutting-edge research across multiple disciplines tells us that the most important factor for women in creating and sustaining a fulfilling sex life, is not what you do in bed or how you do it, but how you feel about it. Which means that stress, mood, trust, and body image are not peripheral factors in a woman’s sexual wellbeing; they are central to it. Once you understand these factors, and how to influence them, you can create for yourself better sex and more profound pleasure than you ever thought possible.And Emily Nagoski can prove it.

    Before humans ruled the earth, there were wolves. Once abundant in North America, these majestic creatures were hunted to near extinction in the lower 48 states by the 1920s. But in recent decades, conservationists have brought wolves back to the Rockies, igniting a battle over the very soul of the West.With novelistic detail, Nate Blakeslee tells the gripping story of one of these wolves, O-Six, a charismatic alpha female named for the year of her birth. Uncommonly powerful, with gray fur and faint black ovals around each eye, O-Six is a kind and merciful leader, a fiercely intelligent fighter, and a doting mother. She is beloved by wolf watchers, particularly renowned naturalist Rick McIntyre, and becomes something of a social media star, with followers around the world.But as she raises her pups and protects her pack, O-Six is challenged on all fronts: by hunters, who compete with wolves for the elk they both prize; by cattle ranchers who are losing livestock and have the ear of politicians; and by other Yellowstone wolves who are vying for control of the park’s stunningly beautiful Lamar Valley.These forces collide in American Wolf, a riveting multi-generational saga of hardship and triumph that tells a larger story about the ongoing cultural clash in the West—between those fighting for a vanishing way of life and those committed to restoring one of the country’s most iconic landscapes.

    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.

    Rather, this is a drop in the ocean, a paddle in the shallow end of sex history, but I hope you will get pleasantly wet nonetheless.The act of sex has not changed since people first worked out what went where, but the ways in which society dictates how sex is culturally understood and performed have varied significantly through the ages. Humans are the only creatures that stigmatise particular sexual practices, and sex remains a deeply divisive issue around the world. Attitudes will change and grow – hopefully for the better – but sex will never be free of stigma or shame unless we acknowledge where it has come from.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    According to revolutionary new research, some birds rival primates and even humans in their remarkable forms of intelligence. In The Genius of Birds, acclaimed author Jennifer Ackerman explores their newly discovered brilliance and how it came about. As she travels around the world to the most cutting-edge frontiers of research, Ackerman not only tells the story of the recently uncovered genius of birds but also delves deeply into the latest findings about the bird brain itself that are shifting our view of what it means to be intelligent. At once personal yet scientific, richly informative and beautifully written, The Genius of Birds celebrates the triumphs of these surprising and fiercely intelligent creatures.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    In The Violinist's Thumb, he explores the wonders of the magical building block of life: DNA.There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists. Kean's vibrant storytelling makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.

    Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. Those in cows and termites digest the plants they eat. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squids with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. I Contain Multitudes is the story of these extraordinary partnerships, between the creatures we are familiar with and those we are not. It reveals how we humans are disrupting these partnerships and how we might manipulate them for our own good. It will change both our view of nature and our sense of where we belong in it.
