Important and provocative, The Undead examines why even with the tools of advanced technology, what we think of as life and death, consciousness and nonconsciousness, is not exactly clear - and how this problem has been further complicated by the business of organ harvesting.

We are all familiar with the idea that machines are powered by electricity, but perhaps not so aware that this is also true for ourselves. "The Spark of Life" is a spectacular account of the body electric, showing how, from before conception to the last breath we draw, electrical signals in our cells are essential to everything we think and do. These signals are produced by some amazing proteins that sit at the forefront of current scientific research - the ion channels. They are found in every cell in Earth and they govern every aspect of our lives, from consciousness to sexual attraction, fighting infection, our ability to see and hear, and the beating of our hearts.

Eye of the Albatross takes us soaring to locales where whales, sea turtles, penguins, and shearwaters flourish in their own quotidian rhythms. Carl Safina’s guide and inspiration is an albatross he calls Amelia, whose life and far-flung flights he describes in fascinating detail. Interwoven with recollections of whalers and famous explorers, Eye of the Albatross probes the unmistakable environmental impact of the encounters between man and marine life.

An astonishing transformation over the last 20,000 years has seen our planet changed from a frigid wasteland into the temperate world within which our civilization has grown and thrived. This dynamic episode in our planet's history, right at the close of the Ice Age, saw not only a huge temperature hike but also the Earth's crust bouncing and bending in response to the melting of the great ice sheets and the filling of the ocean basins - dramatic geophysical events that triggered earthquakes, spawned tsunamis, and provoked a series of eruptions from the world's volcanoes.

Written by award-winning science writer John Emsley, this informative and highly enjoyable book explains the what, the why and the wherefore of the elements. Arranged alphabetically, from Actinium to Zirconium, it is a complete guide to all the elements that are currently known, with more extensive coverage of those we encounter in our everyday life. The entry on each element reveals where it came from, what role it may have in the human body, the foods that contain it, how it was discovered, its role in human health, the uses and misuses to which it is put, and its environmental role.

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness - or chance - plays in evolution.

In this book, Prusiner tells the remarkable story of his discovery of prions - infectious proteins that replicate and cause disease but surprisingly contain no genetic material - and reveals how superb and meticulous science is actually practiced with talented teams of researchers who persevere. He recounts the frustrations and rewards of years of research and offers fascinating portraits of his peers as they raced to discover the causes of fatal brain diseases.

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.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

Perhaps more than any other scientist of our century, Edward O. Wilson has scrutinized animals in their natural settings, tweezing out the dynamics of their social organization, their relationship with their environments, and their behavior, not only for what it tells us about the animals themselves, but for what it can tell us about human nature and our own behavior. He has brought the fascinating and sometimes surprising results of these studies to general readers through a remarkable collection of books.

In Cool, the neuroscientist and philosopher Steven Quartz and the political scientist Anette Asp bring together the latest findings in brain science, economics, and evolutionary biology to form a provocative theory of consumerism, revealing how the brain's "social calculator" and an instinct to rebel are the crucial missing links in understanding the motivations behind our spending habits.

A tiny mutation on the X chromosome can shape a family’s history. Passed down from a “carrier” parent to a child, fragile X syndrome is the most common inherited cause of intellectual disability and autism. Beyond that—and a rarity among genetic disorders—some fragile X carriers not only transmit the mutation, but also experience related conditions themselves.

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.

Que se passe-t-il dans notre cerveau lorsque nous passons de vie à trépas ? Pourquoi son activité persiste-t-elle parfois ? Et qu'est-ce que mourir, au fond ? Aussi étrange que cela paraisse, les frontières de la mort restent mal définies. Et pour cause : depuis la résurrection d'une pendue en 1650 et les électrisations de cadavres menées par Galvani, elles n'ont cessé d'être repoussées. Aujourd'hui, les nouveaux docteurs Frankenstein envisageraient même de greffer un corps pour prolonger la vie...

Qui aurait imaginé, il y a vingt ans à peine, qu'un smartphone saurait reconnaître un visage ou qu'on guérirait l'hémophilie par thérapie génique? Que des robots pilotés depuis la Terre sillonneraient la planète rouge ou qu'on verrait le cerveau en action grâce à l'IRM? Les révolutions scientifiques bouleversent notre quotidien sans que nous en ayons toujours conscience : c'est à ce récit exaltant que nous invite ce livre audio.

A shocking expose of the reckless proliferation of bioweapon research and development facilities across the U.S. - and the threat this poses to everyday Americans. Battling a new generation of corporate giants and uncovering threats right in our own backyard, Kenneth King’s Germs Gone Wild reveals the massive expansion of America’s biodefense research labs and the culture of deception surrounding hundreds of facilities that have opened since 9/11.

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

Nous sommes constamment entourés de vie : abondante, diverse et extraordinaire, elle ne cesse de nous surprendre. Mais savons-nous réellement ce que signifie être en vie ? Sir Paul Nurse, lauréat du prix Nobel de médecine 2001, a passé sa carrière à répondre à cette interrogation. Dans cet ouvrage, il offre une plongée fascinante au cœur des grands concepts qui fondent la science du vivant.
