“A rich sensory trip . . . this indispensable guide to all things smelly is as good as it gets.” —Sunday Telegraph One man's passion for perfume leads him to explore one of the most intriguing scientific mysteries: What makes one molecule smell of garlic while another smells of rose? In...

Who are we, and how did we get here? These are two of the most fundamental and far-reaching questions facing scientists and cosmologists alike and have rested at the center of human intellectual endeavor since its beginning. They are questions that stretch across numerous disciplines. Philosophy, theology, evolutionary biology, and mathematics are just some of the fields looking to explain the emergence of human life.

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.

My First Summer in the Sierra is based on a diary Muir kept while tending sheep in Yosemite country and is filled with the author’s awe for the “divine, enduring, unwasteable wealth” of the natural world. It remains a classic of environmental literature and continues to inspire people.

The Conservation Essentials Collection brings together six classics of American nature writing, wilderness reflection, and early conservation thought. Together these works trace a line from personal communion with nature to the broader conservation ethic that helped shape modern environmental thought.

A thoughtful, illuminating rumination on the life lessons we can take from those who work the land and the millennia of wisdom they draw upon when they go about their day, 'making a living by turning light and time into money'. As with his previous bestsellers, John Connell skilfully synthesises...

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.

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.  

Quantum theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.

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.

When John and Jean Silverwood, both experienced sailors, decided to give their four children a taste of life on the high seas, they hoped the trip would offer important learning experiences - not only about the natural world but about the beauty of human life stripped down to its essence, far from civilization. But the adventure that awaited them would surpass anything they could have imagined.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Essayist. Preservationist. Mountain man. Inventor. John Muir may be California’s best-known icon. A literary naturalist and founder of the Sierra Club and Yosemite National Park, Muir left his legacy on the landscape and on paper. But the celebrity of John Muir does not tell the whole story. In Essential Muir, for the first time, Muir's selected writings include those that show his ecological vision without ignoring his racism, providing a more complete portrait of the man.

Un relato asombroso de un incendio forestal colosal y una exploración panorámica de la relación rápidamente cambiante entre el fuego y la humanidad. En mayo de 2016, Fort McMurray, el centro neurálgico de la industria petrolera canadiense y el mayor proveedor extranjero de Estados Unidos, fue arrasado por un incendio forestal. La catástrofe, valorada en miles de millones de dólares, derritió vehículos, convirtió barrios enteros en bombas incendiarias y expulsó a 88.000 personas de sus hogares en una sola tarde.

Can the mind be explained by what we know about the brain? Is a person’s being determined by their body alone or by their mind and body as separate elements? In this incisive and engaging book, Wilder Penfield, whose work pioneered such research, shares insights into these and other questions, providing an in-depth look at the function of the brain and its relationship to the action of the mind.

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.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws. 

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.

When Robert F. Kennedy, Jr. broke from the Democratic Party and joined forces with Donald Trump, it shocked the political establishment and ignited a movement no one saw coming. Out of that moment came MAHA—Make America Healthy Again—a bipartisan revolution uniting farmers and homesteaders, conservatives and progressives, skeptics and visionaries around a shared mission: healthier food, stronger communities, and freedom from the grip of Big Pharma and Big Ag.

In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. Lead researcher Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so. Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid.
