Genetics Health

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or tainted families and anticipating the outcomes of their marriages.

Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. For some, there has never been a happier food era than today: a time of unusual herbs, farmers' markets, and internet recipe swaps.

Do you live with a chronic, debilitating, yet invisible condition? You may feel isolated, out of step, judged, lonely, or misunderstood - and that's on top of dealing with your actual illness. Take heart. You are not alone, although sometimes it can feel that way. Written by a blogger who suffers from an invisible chronic illness, Surviving and Thriving with an Invisible Chronic Illness offers peer-to-peer support to help you stay sane, be your own advocate, and get back to living your life. This compelling guide is written for anyone suffering with an illness no one can see.

In Survival of the Prettiest, Nancy Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, argues that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism - it's in our biology.

Tribalism is one of the most complex and ancient evolutionary forces; it gave us the capacity for cooperation and competition, and allowed us to navigate increasingly complex social landscapes. It is so powerful that it can predict our behavior even better than race, class, gender, or religion. But in our vast modern world, has this blessing become a curse? Our Tribal Future explores a central paradox of our species: how altruism, community, kindness, and genocide are all driven by the same core adaptation.

The desire for dignity is universal and powerful. It is a motivating force behind all human interaction - in families, in communities, in the business world, and in relationships at the international level. When dignity is violated, the response is likely to involve aggression, even violence, hatred, and vengeance. On the other hand, when people treat one another with dignity, they become more connected and are able to create more meaningful relationships.

A Sick Life chronicles Tionne's journey from a childhood spent in and out of the hospital, told she wouldn't live to see 30 or have children, to becoming the superstar musician who is still living out her life's dream of performing. For the first time, Tionne will tell her full life story - the diagnosis, the tumultuous rise to fame, the life in the spotlight, and the hard-fought advocacy work.

Contrary to conventional wisdom, chronic disease is not genetically predetermined but results from a mismatch between our genes and environment and lifestyle. What we call a "disease" is the outcome of an imbalance in one or more of the seven core physiological processes. Leveraging a lifetime on the cutting edge of research and practice, Dr. Jeffrey S. Bland lays out a road map for good health by helping us understand these processes and the root causes of chronic illness.

In this captivating book, neuroscientist Shane O'Mara invites us to marvel at the benefits walking confers on our bodies and brains, and to appreciate the advantages of this uniquely human skill. From walking's evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting-edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our "inner GPS" system.

Throughout history, even as daily life has exhibited calm and tolerance, war has never been far away, and even within societies, violence can be a threat. The Goodness Paradox gives a new and powerful argument for how and why this uncanny combination of peacefulness and violence crystallized after our ancestors acquired language in Africa a quarter of a million years ago.

Breakthroughs in genetics present us with a promise and a predicament. The promise is that we will soon be able to treat and prevent a host of debilitating diseases. The predicament is that our newfound genetic knowledge may enable us to manipulate our nature - to enhance our genetic traits and those of our children. Although most people find at least some forms of genetic engineering disquieting, it is not easy to articulate why.

In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are "nasty, brutish, and short," why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy.

Did you know women walk more, eat less, socialize more, meet more men, dance more, and flirt more when they're ovulating? Or that PMS may have evolved to get rid of boyfriends with unfit sperm? Behind the "fickle" differences in what women find sexy about men, or what they like to wear, there's a hidden adaptive intelligence shaped over eons. Rather than making women irrational - as the conventional and irredeemably sexist wisdom goes - the female hormonal cycle has been exquisitely fine-tuned to give women the advantages they needed to succeed in our ancestral environments, and perhaps also today.

The scientific evidence behind why maintaining a lifestyle more like that of our ancestors will restore our health and well-being. In Go Wild, Harvard Medical School Professor John Ratey, MD, and journalist Richard Manning reveal that although civilization has rapidly evolved, our bodies have not kept pace.

Control is a book about what geneticist Adam Rutherford calls “a defining idea of the twentieth century.” Inspired by Darwin’s ideas about evolution, eugenics arose in Victorian England as a theory for improving the British population, and quickly spread to America. With disarming wit and scientific precision, Rutherford explains why eugenics still figures prominently in the twenty-first century, despite its genocidal past. And he confronts insidious recurring questions, revealing the intellectual bankruptcy of the idea, and the scientific impossibility of its realization.

A compelling memoir by ABC News correspondent James Longman in which he discusses mental illness and trauma in families, what the latest genetic science is telling us, and how to not only persevere but thrive.

Around 250,000 people have had their genomes sequenced, and scientists expect that number to rise to one billion by 2025. Professor Steven J. Heine argues that the first thing we will do on receiving our DNA test results is to misinterpret them completely. Despite breathless (often lightly researched) media coverage about newly discovered "cancer" or "divorce" or "IQ" genes, the prospect of a DNA test forecasting how your life is going to turn out is vanishingly small.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

In Sleepyhead, science writer Henry Nicholls uses his own experience with chronic narcolepsy as a gateway to better understanding the cryptic, curious, and relatively uncharted world of sleep disorders. Charming, eye-opening, and deeply humanizing, Sleepyhead will help us all uncover the secrets of a good night's sleep.
