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.

An award-winning physician and scientist makes the game-changing case that genetic females are stronger than males at every stage of life. Here are some facts: Women live longer than men. They have stronger immune systems. They're better at fighting cancer and surviving famine and even see the world in a wider variety of colours. They are simply stronger than men at every stage of life. Why is this? And why are we taught the opposite?

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

Oxford Case Histories in Infection and Microbiology contains over 45 well structured cases, providing comprehensive coverage of the diagnostic and management dilemmas in clinical microbiology and infectious diseases. Each case comprises of a brief patient history with relevant clinical examination findings, thus insuring the listener is aware of how to confirm a diagnosis rapidly, with reference throughout to laboratory techniques, advice on therapy, epidemiological features, and areas which can be controversial.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

Emmy Award - winning filmmaker, writer, and naturalist Joe Hutto has done it again. Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

Antibiotics are powerful drugs that can prevent and treat infections, but they are becoming less effective as a result of drug resistance. Resistance develops because the bacteria that antibiotics target can evolve ways to defend themselves against these drugs. When antibiotics fail, there is very little else to prevent an infection from spreading. Unnecessary use of antibiotics in both humans and animals accelerates the evolution of drug-resistant bacteria, with potentially catastrophic personal and global consequences.

Every one of us contains a billion times more atoms than all the grains of sand in the earth’s deserts. If you weigh 150 pounds, you’ve got enough carbon to make 25 pounds of charcoal, enough salt to fill a saltshaker, enough chlorine to disinfect several backyard swimming pools, and enough iron to forge a 3-inch nail. But how did these elements combine to make us human?

Though you may not be able to see them with the naked eye, parasites inhabit our everyday lives. From headlice to bird droppings, litterboxes to unfiltered water, you have brushed up against the most common way of life on our planet. In this unique book, John Janovy Jr., one of the world's preeminent experts on parasites, reveals what can humans learn from the most reviled yet misunderstood animals on Earth: lice, tapeworms, flukes, and maggots that can eat a lizard from the inside, and how these lessons help us negotiate our own complicated world.

Could humans unknowingly be a part of a larger superorganism—one with its own motivations and goals, one that is alive, and conscious, and has the power to shape the future of our species? This is the fascinating theory from author and futurist Byron Reese, who calls this human superorganism “Agora.” In We Are Agora, Reese starts by asking the question, “What is life and how did it form?” From there, he looks at how multicellular life came about, how consciousness emerged, and how other superorganisms in nature have formed.

For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography.

Now in audio - a fascinating work of popular science from a world-renowned expert on mosquitoes and a prize-winning reporter. In this lively and comprehensive portrait of the mosquito, its role in history, and its threat to mankind, Spielman and D'Antonio take a mosquito's-eye view of nature and man. They show us how mosquitoes breed, live, mate, and die and introduce us to their enemies, both natural and man-made.

For most of us, the only thing we know about flies is that they're annoying, and our usual reaction is to try to kill them. In Super Fly, the myth-busting biologist Jonathan Balcombe shows the order Diptera in all of its diversity, illustrating the essential role that flies play in every ecosystem in the world as pollinators, waste-disposers, predators, and food source; and how flies continue to reshape our understanding of evolution.

An eye-opening look into why our bodies work - or don’t - the way they do. From blurry vision to crooked teeth, ACLs (anterior cruciate ligaments) that tear at alarming rates and spines that seem to spend a lifetime falling apart, it’s surprising that human beings have beaten the odds as a species. After all, we’re the only survivors on our branch of the tree of life. In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us from where we inherited our adaptable, achy, brilliant bodies in the process of evolution.

Topics explored in this dialogue include: how you can address the greatest challenge of our times, the role of the arts in deep ecology, how the shift from linear thinking to systems thinking in the sciences affects us now and in the future, understanding the complexity of living systems and life itself, why creativity is the driving force of evolution, what religion and deep ecology have in common, what's really behind the information age, and the mathematics of complexity.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

Like Solomon with his magic ring, famed Austrian ethologist Konrad Lorenz was a gifted student of the animal world. King Solomon's Ring, which brought him worldwide recognition, is a delightful collection of observations and insights into the lives of our furry and feathered friends, from our familiar furry companions to water shrews and jackdaws. A must listen for any animal lover.

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.
