The study of sexual physiology has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, "The funniest science writer in the country", devoted the past two years to stepping behind those doors. In Bonk, Roach shows us how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.

Why do women live longer than men? Why do women have menopause? Why are women more likely to get Alzheimer’s? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? And does the female brain really exist? In Eve, Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex.

The extraordinary Siddhartha Mukherjee has written a biography of the gene as deft, brilliant, and illuminating as his extraordinarily successful biography of cancer. Weaving science, social history, and personal narrative to tell us the story of one of the most important conceptual breakthroughs of modern times, Mukherjee animates the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices.

We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Works presents captivating new ideas and surprising answers to questions about contraception, fertility, circumcision, menopause, STDs, homosexuality, orgasms, and more. This is an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.

A list of the attributes that define a mammal is a ragbag of things - fur, live birth, three bones in the middle ear, a brain whose two halves are robustly joined together.... But this curious collection of features contain the roots of all the biology that makes us what we are: monkeys with massive brains who parent extensively, enjoy sport and think lots. Which is to say, what makes us mammals makes us human.

More than 90 percent of sexually active women have only been given a very limited amount of information about how birth control works, often right at the beginning when they start their first pill or patch. Not all of us enjoy biology lessons, and figuring out the complexities of hormones, cycles, and our bodies can feel a little too much. But it doesn’t need to be rocket science. Getting a better insight into how your body really works can empower you and open up choices and possibilities so that you make the best decisions for yourself. After all, this is your body!

A riveting investigation of the myriad ways that parasites control how other creatures - including humans - think, feel, and act. These tiny organisms can live only inside another animal, and, as McAuliffe reveals, they have many evolutionary motives for manipulating their host's behavior. Far more often than appreciated, these puppeteers orchestrate the interplay between predator and prey.

The story of evolution as you’ve never heard it before. What’s the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Menno Schilthuizen invites listeners to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles.

What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee.

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or "gene editing". Using this approach, scientists can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago.

In his first best seller, The End of Illness, David Agus revealed how to add vibrant years to your life by knowing the real facts of health. In this book he builds on that theme by showing why this is the luckiest time yet to be alive, giving you the keys to the new kingdom of wellness. Medicine is undergoing rapid change. In the old world, you followed general principles, and doctors treated you based on broad, one-size-fits-all solutions.

Here are some facts: Women live longer than men. They have stronger immune systems. They're better at fighting cancer and surviving famine, and even see the world in a wider variety of colors. They are simply stronger than men at every stage of life. Why is this? And why are we taught the opposite? To find out, Dr. Sharon Moalem drew on his own medical experiences - treating premature babies in the neonatal intensive care unit; recruiting the elderly for neurogenetic studies; and more - and tried to understand why in every instance men were consistently less likely to thrive.

How did a deadly genetic disease help our ancestors survive the bubonic plagues of Europe? Was diabetes evolution's response to the last Ice Age? Will a visit to the tanning salon help bring down your cholesterol? Why do we age? Why are some people immune to HIV? Can your genes be turned on or off? Survival of the Sickest reveals the answers to these and many other questions as it unravels the amazing connections between evolution, disease, and human health today.

Lurking in our homes, hiding in our offices, and polluting the air we breathe is something sinister. Something we’ve turned a blind eye to for far too long. Dr. Leonardo Trasande, a pediatrician, professor, and world-renowned researcher, tells the story of how our everyday surroundings are making us sicker, fatter, and poorer. Through a blend of narrative, scientific detective work, and concrete information about the connections between chemicals and disease, he reveals what we can do to protect ourselves and our families in the short-term, and how we can help bring the change we deserve.

Why are conditions like autism, asthma, obesity, and allergies exploding at unprecedented rates? Why are we living longer, getting smarter, having far fewer kids? If Darwin were alive today, how would he explain this new world?

An Epidemic of Absence asks what will happen in developing countries, which, as they become more affluent, have already seen an uptick in allergic disease: Will India end up more allergic than Europe? Velasquez-Manoff also details a controversial underground movement that has coalesced around the treatment of immune-mediated disorders with parasites. Against much of his better judgment, he joins these do-it-yourselfers and reports his surprising results.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

In Missing Microbes, Dr. Martin J. Blaser invites us into the wilds of the human microbiome, where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the health and equilibrium of our body. Now this invisible eden is being irrevocably damaged by some of our most revered medical advances-antibiotics-threatening the extinction of our irreplaceable microbes with terrible health consequences.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

Over a decade ago, as the Human Genome Project completed its mapping of the entire human genome, hopes ran high that we would rapidly be able to use our knowledge of human genes to tackle many inherited diseases, and understand what makes us unique among animals. But things didn't turn out that way.

A scientific and medical revolution has crept up on us, based on study after study, from hundreds of laboratories around the world. It is no longer just a theoretical shift: every one of us will be touched by it, and many of us already have been. The meaning of disease, our understanding of the human body, and crucial decisions about what we all need to know and what choices we make about our health are at stake. Welcome to the new world of personalized medicine.

In this landmark book of popular science, Daniel E. Lieberman - chair of the department of human evolutionary biology at Harvard University and a leader in the field - gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease.
