Over the past decade neuroscience has uncovered a wealth of new information about our senses and how they serve as our gateway to the world. This splendidly accessible book explores the most intriguing findings of this research. With infectious enthusiasm, Rob DeSalle illuminates not only how we see, hear, smell, touch, taste, maintain balance, feel pain, and rely on other less familiar senses, but also how these senses shape our perception of the world aesthetically, artistically, and musically.

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.

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.

Nos pasamos toda una vida con un solo cuerpo y casi no sabemos cómo funciona. Desde los genes hasta nuestra capacidad de hablar, pasando por nuestras constantes adaptaciones al medio y los riesgos que corremos, este libro nos descubre que nuestro microcosmos es un verdadero milagro, lleno de prodigios y de secretos asombrosos. Explicar el cuerpo humano en toda su integridad, y hacerlo para todos los públicos, solo está al alcance de un autor como Bill Bryson.

Human bone is versatile and entirely unique: It repairs itself without scarring, it's lightweight but responds to stresses, and it's durable enough to survive for millennia. In Bones, orthopedic surgeon Roy A. Meals explores and extols this amazing material that both supports and records vertebrate life.

How is it that a baboon and a blob of slime mould instinctively know what to eat for optimal health, balancing their protein, fat and carb intake in perfect proportions? In new, groundbreaking research that is transforming our understanding of nutrition, animals from locusts to lions and yes, humans too, demonstrate the remarkable science behind appetite.

Adaptable takes us on a tour of the human body. In each chapter, we learn how our bodies navigate an uncertain world: how we grow and mature; how our brains develop and learn; how our hearts, lungs, and digestive systems deliver oxygen and nutrients; how we manage toxins, temperature, and water balance; how we move and reproduce; how our immune system keeps invaders at bay; and how we age and decline. Along the way, we learn how to take care of our remarkable bodies, and that the universe of healthy lifestyles is vast (we don’t need the latest fad diet or cleanse!).

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

With so much variation that can be handed down genetically, for better or worse, the way we understand our biology holds huge importance for how we understand our world and one another, including the biggest questions of our day, such as social inequality. Eye-opening and profound, Adaptable is a revolutionary reappraisal of an overlooked science.

A comprehensive guide to everything one needs to know about the male reproductive system.

We like to think of ourselves as highly evolved creatures. But if we are evolution's greatest creation, why are we so badly designed? We have retinas that face backward, the stump of a tail, and way too many bones in our wrists. We must find vitamins and nutrients in our diets that other animals simply make for themselves. Millions of us can't reproduce successfully without help from modern science. We have nerves that take bizarre paths, muscles that attach to nothing, and lymph nodes that do more harm than good. And that's just the beginning of the story.
