Thought of as the seat of our soul, then as a mysteriously animated object, the heart is still more a mystery than it is understood. Why do most animals only get one billion beats? (And how did modern humans get to over two billion - effectively letting us live out two lives?) Why are sufferers of gingivitis more likely to have heart attacks? And what does it really feel like to touch your own heart, or to have someone else's beating inside your chest?

Although vital to our well-being and even to our success as a species, the physical sense of balance has never attained the same recognition as sight, hearing, touch, smell, or taste. Now, with an epidemic of debilitating falls sweeping America's aging population, the time is ripe for a lively and illuminating tour of the human body's most exquisitely intricate and least understood faculty.

Expand your memory, concentration, energy, and learning ability with this 4-step holistic program which helps your brain perform at optimum mental ability. Dr. Dharma Singh Khalsa's Brain Longevity Program uses complementary medicine from Eastern and Western traditions, along with nutritional therapy, stress management, exercise therapy, and pharmacology, to reduce the effects of "normal" brain aging.

Spotting a face in a crowd is so easy, you take it for granted. But how you do it is one of science's great mysteries. And vision is involved with so much of everything your brain does. Explaining how it works reveals more than just how you see. In We Know It When We See It, Harvard neuroscientist Richard Masland tackles vital questions about how the brain processes information - how it perceives, learns, and remembers - through a careful study of the inner life of the eye.

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.

A natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements Even when the floors are sparkling clean and the house seems silent, our domestic domain is wild beyond imagination. In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

This lively and informative exploration of the heart offers a perfect mix of medical fact and amusing anecdote. A prospective cardiologist and former paramedic - as well as one of Germany's most successful science-slammers - von Borstel relates his own experiences to provide a personal insight into the human side of heart medicine while clearly explaining the science behind cardiac disease and healthcare for the heart.

With its trillions of connections, the human brain is more beautiful and complex than anything we could ever build, but it’s far from perfect: our memory is unreliable; we can’t multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but.

Over the past 200 years, human life expectancy has approximately doubled. Yet we face soaring worldwide rates of obesity, diabetes, high blood pressure, mental illness, heart disease, and stroke. In his fascinating new book, Dr. Lee Goldman presents a radical explanation: The key protective traits that once ensured our species' survival are now the leading global causes of illness and death.

As a health-care journalist, Kate Pickert knew the emotional highs and lows of medical treatment well - but always from a distance, through the stories of her subjects. That is, until she was unexpectedly diagnosed with an aggressive type of breast cancer at the age of 35. As she underwent more than a year of treatment, Pickert realized that the popular understanding of breast care in America bears little resemblance to the experiences of today's patients and the rapidly changing science designed to save their lives.

The human body is like an exceedingly well-fortified castle, defended by billions of soldiers - some live for less than a day, others remember battles for decades, but all are essential in protecting us from disease. This hidden army is our immune system, and without it we could not survive the eternal war between us and our microscopic enemies. Immune explores the incredible arsenal that lives within us - how it knows what to attack and what to defend and how it kills everything from the common cold to the plague bacterium.

What happens when we accept that everything we feel and think stems not from an immaterial spirit but from electrical and chemical activity in our brains? In this thought-provoking narrative - drawn from professional expertise as well as personal life experiences - trailblazing neurophilosopher Patricia S. Churchland grounds the philosophy of mind in the essential ingredients of biology. She reflects with humor on how she came to harmonize science and philosophy, the mind and the brain, abstract ideals and daily life.

The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs' clinic to the present.

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 gives the human brain the creative ability that defines us all as individuals? Although the silicon version is hard on its heels, the brain remains the most remarkable computer in existence. Leading us through cognitive theory, neuroscience and Darwinian evolution with his trademark wit and wisdom, Michael Corballis explains what we know - and don't know - about our minds. How do we know if we’re really the top dogs in brain power?

From the creators of the wildly popular and seriously scientific YouTube channel AsapSCIENCE comes entertaining, irreverent, and totally accessible answers to the questions you never got to ask in science class.

In Cracking the Aging Code, theoretical biologist Josh Mitteldorf and award-winning writer and ecological philosopher Dorion Sagan reveal that evolution and aging are even more complex and breathtaking than we originally thought. Using meticulous multidisciplinary science as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that "just happens", nor is it the result of wear and tear or a genetic inevitability.

Take a "fantastic voyage" through the whorls and curves of the human brain, no miniaturization required. Learn everything from how quickly you can possibly think (and that left-handed people think faster) to why being bad feels so good (yes, there's a biochemical explanation).
