Vor 100.000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70.000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens.

Why do women live longer than men? Why do women have menopause? Why are women more likely to get Alzheimer’s? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? And does the female brain really exist? In Eve, Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex.

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.

Bacteria form a fundamental branch of life. They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease.

For decades, biology has been dominated by the study of genetic information. Information is important, but it is only part of what makes us alive. Our inheritance also includes our living metabolic network, a flame passed from generation to generation, right back to the origin of life. In Transformer, biochemist Nick Lane reveals a scientific renaissance that is hiding in plain sight-how the same simple chemistry gives rise to life and causes our demise.

A fascinating tour of creatures from the surface to the deepest ocean floor: How Far the Light Reaches invites us to envision wilder, grander, and more abundant possibilities for the way we live. Conservation journalist Sabrina Imbler discovers that some of the most radical models of family, community, and care can be found in the sea, from gelatinous chains that are both individual organisms and colonies of clones to deep-sea crabs that have no need for the sun, nourished instead by the chemicals and heat throbbing from the core of the Earth.

Genetic engineering expert Dr Alina Chan and renowned science writer Matt Ridley examine the origins of SARS-CoV-2, the virus responsible for COVID-19, using their formidable skills to scrutinise arguments and rigorously analyse the sprawling data. Viral is a fascinating account that takes in pangolins, horseshoe bats, internet sleuths and misleading scientific papers. It details the evidence and investigates hypotheses for the virus origin, chief among them a potential laboratory leak or a natural spillover.

We harbor roughly the same number of microbes as we have cells. This complex ecosystem is crucial to our health, affecting many processes including immunity, child development, and bone density regulation. Research in this area has exploded, and in this audiobook, we highlight some of the most exciting work on how the microbiome develops, its influence on brain and behavior, and implications in both contributing to and treating various disorders.

Under the Sea Wind is a classic wilderness adventure to which all nature writing is compared. The hero of Under the Sea Wind is soon seen to be life itself, that quicksilver prize granted, for a brief time only, to the clever and the fortunate.

Promising treatments now in more than 35,000 clinical trials could have dramatic impacts on cancer, autoimmune diseases, organ replacement, heart disease, and even aging itself. These treatments, which are saving the lives of patients in the trials, will soon be rolled to the medical community at large. The key to these breakthroughs is the use of living cells as medicine instead of traditional drugs. Research has found that our bodies are virtual treasure troves of adult cells that act as agents of remarkable healing and repair.

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites listeners to explore and learn from the elegantly simple lives of mosses.

From birthdays to birth rates to how we perceive the passing of time, mathematical patterns shape our lives. But for those of us who left math behind in high school, the numbers and figures hurled at us as we go about our days can sometimes leave us scratching our heads, feeling as if we're fumbling through a mathematical minefield.

The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.

Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts.

With all the advances in science in the last century, why are there still so many infectious diseases? Why haven’t we found cures for difficult cancers? Why hasn’t any major progress been made in the treatment of mental illness? And how do we intend to stop, and not only that but reverse, global warming and the climate crisis? In Saved by Science, scientist Mark Poznansky examines the many crises facing humanity while encouraging us with the promise of an emerging solution: synthetic biology.

The question of how and why organisms age has teased scientists for centuries. There are myriad competing theories, from the idea that ageing is a simple wear and tear process, like the rusting of a car, to the belief that ageing and death are genetically programmed and controlled. In fact, there is no clearly defined limit to life and no single, predictable program playing itself out: different things are happening within and between tissues, and each system or organ accumulates damage at its own pace, according to the kind of insults imposed on it by daily living.

In Cracking the Aging Code, theoretical biologist Josh Mitteldorf and award-winning writer and ecological philosopher Dorion Sagan reveal that evolution and aging are even more complex and breathtaking than we originally thought. Using meticulous multidisciplinary science as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that "just happens", nor is it the result of wear and tear or a genetic inevitability.

In all animals, mating is a deal. But few creatures behave as if sex is a simple transaction. Many treat it with reverence, suspicion, angst and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an exhausting and sometimes deadly ritual called a ‘lek’. To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers.

In this glorious celebration of the night, New York Times bestselling nature writer Leigh Ann Henion invites us to leave our well-lit homes, step outside, and embrace the dark as a profoundly beautiful part of the world we inhabit. Because no matter where we live, we are surrounded by animals that rise with the moon, and blooms that reveal themselves as light fades. Henion explores her home region of Appalachia, where she attends a synchronous firefly event in Tennessee, a bat outing in Alabama, and a moth festival in Ohio.
