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.

A riveting exploration of how microbes are transforming the way we see nature and ourselves - and could revolutionize agriculture and medicine. Prepare to set aside what you think you know about yourself and microbes. Good health - for people and for plants - depends on Earth's smallest creatures. The Hidden Half of Nature tells the story of our tangled relationship with microbes and their potential to revolutionize agriculture and medicine, from garden to gut.

We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life, supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and the humble peppercorn drove the Age of Discovery, so did coffee beans help fuel the Enlightenment and cottonseed help spark the Industrial Revolution. And from the fall of Rome to the Arab Spring, the fate of nations continues to hinge on the seeds of a Middle Eastern grass known as wheat.

Despite advances in health care, infectious microbes continue to be a formidable adversary to scientists and doctors. Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.

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.

At once elegant and riveting, Sync tells the story of the dawn of a new science. Steven Strogatz, a leading mathematician in the fields of chaos and complexity theory, explains how enormous systems can synchronize themselves, from the electrons in a superconductor to the pacemaker cells in our hearts. He shows that although these phenomena might seem unrelated on the surface, at a deeper level there is a connection, forged by the unifying power of mathematics.

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.

A moving collection of fishing stories by one of America’s legendary outdoor writers. Throughout his career, Harry Middleton contributed hundreds of stories, essays, and book reviews to some of the most respected periodicals, including the New York Times, Sports Illustrated, Gray’s Sporting Journal, Field & Stream, Country Journal, Smithsonian, and Sierra, among others.

Edward O. Wilson has distilled sixty years of teaching into a book for students, young and old. Reflecting on his coming-of-age in the South as a Boy Scout and a lover of ants and butterflies, Wilson threads these twenty-one letters, each richly illustrated, with autobiographical anecdotes that illuminate his career - both his successes and his failures - and his motivations for becoming a biologist.

De plus en plus, des percées déroutantes redéfinissent la biologie. Le fondateur de la chaîne YouTube DirtyBiology s'en fait l'écho et propose des informations impertinentes et instructives sur les gènes, la vie ou l'évolution.

Smell is the most emotional and evocative of our senses: it can bring back memories faster and with more immediacy than a photograph - so why is it so little understood? Armed with a hungry curiosity and a willingness to self-experiment, author Barney Shaw goes in search of the hidden meanings of smells. Using plain words to describe what he finds, he investigates the chemistry, psychology, history and future of this underappreciated sense.

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.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

Our basic right to healthy food is at risk. What can we do? Written in an astute, engaging style, armed with examples from her own homesteading lifestyle, small farmer Nicole Faires' Food Confidential gives you the tools to fight the intangible battles as well as the practical ones.

This science classic by Paul de Kruif chronicles the pioneering bacteriological work of the first scientists to see and learn from the microscopic world. Paul de Kruif's Microbe Hunters is a timeless dramatization of the scientists, bacteriologists, doctors, and medical technicians who discovered microbes and invented the vaccines to counter them.

Feathers are an evolutionary marvel: Aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?

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.

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

We all learn at least one language as children. But what does it take to learn six languages...or seventy? In Babel No More, Michael Erard, "a monolingual with benefits," sets out on a quest to meet language superlearners and make sense of their mental powers. On the way he uncovers the secrets of historical figures like Italian cardinal Giuseppe Mezzofanti, who was said to speak seventy-two languages; Emil Krebs, a pugnacious German diplomat, who spoke sixty-eight languages; and Lomb Kat, a Hungarian who taught herself Russian by reading Russian romance novels.
