Die packende Biografie eines Mannes, der über 10.000 Stunden unter Wasser verbracht, Tauchboote und ein Unterwasserhaus gebaut, verschüttete Schätze aus Brunnen und Meeren geborgen und den Quastenflosser und andere faszinierende Lebensformen erforscht hat: Hans Frickes Buch ist abenteuerliche Tauchgeschichte, lebendiger Forschungsbericht, Ökothriller - und eine poetische Liebeserklärung an die Unterwasserwelt. Als er 11 Jahre alt ist, bastelt er sich aus Feuerlöscher und Gasmaske eine Tauchausrüstung,

Genomics has transformed the biological sciences. From epidemiology and medicine to evolution and forensics, the ability to determine an organism's complete genetic makeup has changed the way science is done and the questions that can be asked of it. John Archibald explores the science of genomics and its rapidly expanding toolbox. Archibald tells us how the field of genomics is on the cusp of another quantum leap; the implications for science and society are profound.

Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

Hace 13.000 años la evolución de las distintas sociedades humanas comenzó a tomar rumbos diferentes. La temprana domesticación de animales y el cultivo de plantas silvestres en el Creciente Fértil, China, Mesoamérica y otras zonas geográficas otorgó una ventaja inicial a sus habitantes. Sin embargo, los orígenes localizados de la agricultura y la ganadería son solo una parte de la explicación de los diferentes destinos. Las sociedades que superaron esta fase de cazadores-recolectores se encontraron con más probabilidades de desarrollo, supervivencia y poder bélico.

Trying to understand our human origins has always been a fundamental part of who we are. Today, with the help of dramatic archaeological discoveries and groundbreaking advancements in technology and scientific understanding, we are closer than we've ever been to learning the true story. In recent decades, it has been the science of paleoanthropology that has led the investigation, helping us make sense of this controversial subject and providing us with a richer understanding of our origins.

Few fish are as beloved, or as obsessed over, as the American shad. Although shad spend most of their lives in salt water, they enter rivers by the hundreds of thousands in the spring and swim upstream heroic distances in order to spawn, then return to the ocean.

What scientific concept would improve everybody's cognitive toolkit? This is the question John Brockman, publisher of Edge.org, posed to the world's most influential thinkers. Their visionary answers flow from the frontiers of psychology, philosophy, economics, physics, sociology, and more. Surprising and enlightening, these insights will revolutionize the way you think about yourself and the world.

Geneticists like David Reich have made astounding advances in the field of genomics, which is proving to be as important as archaeology, linguistics, and written records as a means to understand our ancestry. In Who We Are and How We Got Here, Reich allows listeners to discover how the human genome provides not only all the information a human embryo needs to develop but also the hidden story of our species.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.

50 Things to Know About Birds in New York: Encountering Beautiful Species in the Empire State by John Duffy offers a unique approach to learning about the birds of New York. Most books on the subject provide a list of species’ identification marks, sounds, and typical habitats. Books about visiting New York might include places to go birdwatching.

Once again, John Gierach tells the world why the pastime of fly-fishing makes so much sense—except when it doesn't. In sparkling prose, with more than a touch of humor, he recalls the joys of landing that trout he's been watching for the last hour—and then losing an even fatter one a little later. Joy and frustration mix in Gierach's latest appreciation of the fly-fishing life as he takes us from his home waters on the Front Range of the Rockies in Colorado to fishing meccas all over North America.

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.

In All Fishermen Are Liars, Gierach travels around North America seeking out quintessential fishing experiences, whether it's at a busy stream or a secluded lake hidden amid snow-capped mountains. He talks about the art of fly-tying and the quest for the perfect steelhead fly ("The Nuclear Option"), about fishing in the Presidential Pools previously fished by the elder George Bush, and the importance of traveling with like-minded companions when caught in a soaking rain.

A month by month handbook for foraging in the woods, fields and seashores of Great Britain. Look out of your window, walk down a country path or go to the beach in Great Britain and you are sure to see many wild species that you can take home and eat. From dandelions in spring to sloe berries in autumn, via wild garlic, samphire, chanterelles and even grasshoppers, our countryside is full of edible delights in any season.

John Parrington draws on the latest research on the human brain to show how it differs strikingly from those of other animals in its structure and function at a molecular and cellular level. And he argues that this 'shift', enlarging the brain, giving it greater flexibility and enabling higher functions such as imagination, was driven by tool use, but especially by the development of one remarkable tool - language.

With his inimitable combination of wit and wisdom, John Gierach once again celebrates the fly-fishing life in Standing in a River Waving a Stick and notes its benefits as a sport, philosophical pursuit, even therapy: "The solution to any problem-work, love, money, whatever-is to go fishing, and the worse the problem, the longer the trip should be." After all, fly-fishing does teach important life lessons, says Gierach-about solitude, patience, perspective, humor, and the sublime coffee break.

John Gierach is known for his witty, trenchant observations about fly-fishing. In A Fly Rod of Your Own, Gierach once again takes us into his world and scrutinizes the art of fly-fishing. He travels to remote fishing locations where the airport is not much bigger than a garage and a flight might be held up because a passenger is running late. He sings the praises of the skilled pilots who fly to remote fishing lodges in tricky locations and bad weather.

In clear, concise language, Professor Young explains the basic categories of cells and tissues and then delves into their specialized functions, whether it be for muscle cells and nervous tissue or the cells of reproductive organs and the highly unusual entities known as "extreme" cells. Finally, Professor Young wraps up the lectures with a topic of universal interest-the death and aging of cells.

America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation's ships and houses, barns, and bridges. Yet this popularity came at a cost: by the end of the nineteenth century, clear cutting had decimated much of America's white pine forests. In White Pine, ecologist and writer John Pastor takes listeners on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal.
