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.

From the cup of coffee that jump-starts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit...except for inducing intoxication.

This engaging memoir reveals the true story of the Search for ExtraterrestrialIntelligence (SETI), and discloses what we may very soon discover. Chronicling the program’s history with insight and humor, SETI senior astronomer Seth Shostak assures us that if there is sentient life in the universe, we are within decades of picking up its signal.

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.

For many of us, the buzzing of a bee elicits panic. But the next time you hear that low droning sound, look closer: the bee has navigated to this particular spot for a reason using a fascinating set of tools. What a Bee Knows: Exploring the Thoughts, Memories, and Personalities of Bees invites us to follow bees' mysterious paths and experience their alien world.

For many of us, the great scientific discoveries of the modern age—the Big Bang, evolution, quantum physics, relativity—point to an existence that is bleak, devoid of meaning, pointless. But in The Sacred Depths of Nature, eminent biologist Ursula Goodenough shows us that the scientific world view need not be a source of despair. Indeed, it can be a wellspring of solace and hope. This volume reconciles the modern scientific understanding of reality with our timeless spiritual yearnings for reverence and continuity.

As dramatic as The Double Helix and as absorbing as The Soul of a New Machine, Natural Obsessions explores the advanced reaches of molecular biology, the nature of the human cell, and the genes that control cancer. It unforgettably portrays some of the best young scientists in the world, the rewards and discouragements of scientific research, and the very process of scientific inquiry.

With breathtaking clarity, Compost Science for Gardeners demystifies composting practices and helps listeners determine the best technique for their unique situation. This comprehensive science-based book is your key to building healthier soil and growing better plants.

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration.

Insects might make us recoil in repugnance, but they also manufacture - or make possible in other ways - many of the things we take for granted in our daily lives. When we bite into a shiny apple, listen to the resonant notes of a violin, try on the latest fashions, receive a dental implant, or get a manicure, we are mingling with the by-products of their everyday lives.

Wenn Biologen bei Freunden zum Essen eingeladen sind, müssen sie immer wieder die ganz existentiellen Fragen beantworten - manchmal auch die intimen und die ekligen. Was bezweckt eine Nachtigall, wenn sie singt? Haben Goldfische einen Penis? Wird man krank, wenn man am Biofilm im Kühlschrank leckt? In diesem Original Podcast leisten eine in allen Lebenslagen erfahrene marine Mikrobiologin und ein Experte für Amphibien und Reptilien erste Info-Hilfe, zusammen mit einem Journalisten, der eine unschlagbare Begeisterung für alles Lebendige hat.

When a good friend with a severe illness wrote, asking if he might have his “green burial” at Bernd Heinrich’s hunting camp in Maine, it inspired the acclaimed biologist to investigate a subject that had long fascinated him. How exactly does the animal world deal with the flip side of the life cycle? And what are the lessons, ecological to spiritual, raised by a close look at how the animal world renews itself?

This download showcases some of the most exquisite sounds that can be heard in the natural world, from the rich, melodious songs of the Blackbird, Pied Butcherbird and Nightingale that are full of complexity, ingenuity and perfectly arranged phrases, to the breathtaking compositions of the Skylark, Albert's Lyrebird and White-rumped Shama, and the rhythmical variations on a theme from the Chiming Wedgebill and White-browed Robin-chat.

Choosing a profession begins with imagining yourself in a career. Now New York Times best-selling author Virginia Morell dives into the adventures of a marine biologist team, allowing a much needed, in-depth look into the field. Becoming a Marine Biologist explores how successful marine biologists curated their careers and what they suggest to young people today who feel called to protect our oceans by studying the sea and its inhabitants.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species.

Fruit flies, silverfish, dandelions, and crabgrass are the bane of many people and the target of numerous chemical and physical eradication efforts. In this compelling reassessment of the relationship between humans and the natural world, John Hainze - an entomologist and former pesticide developer - considers the fascinating and bizarre history of how these so-called invasive or unwanted pests and weeds have co-evolved with humanity and highlights the benefits of a greater respect and moral consideration toward these organisms.
