Mummie del ghiaccio, delle cripte e delle catacombe, arrivate fino a noi dalle Ande alla Cina. I diversi processi di mummificazione, a cui sono stati sottoposti - per citare tre casi famosi - Ötzi, Tutankhamon, Evita Perón, ci permettono di affondare lo sguardo nelle condizioni di vita degli uomini del passato. Grazie ai metodi più avanzati della bioarcheologia molecolare, inoltre, si può far luce sulle patologie antiche e trarne informazioni importanti sull'evoluzione di alcune malattie del nostro tempo.

Vi går gennem hele livet i en og samme krop, og alligevel ved de fleste af os stort set intet om, hvordan vores krop fungerer, og hvad der sker inden i os. Dette gør den formidable videnskabsformidler Bill Bryson, forfatter til bl.a. bestselleren "En kort historie om næsten alt", noget ved. I "Kroppen - en guide for indehavere" tager han os med på en dybt fascinerende rejse fra top til tå og anskueliggør det vidunder, vores legeme er.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

On the Origin of Species (1859) by Charles Darwin is a work of scientific literature considered to be the foundation of evolutionary biology. The book introduced the theory that populations evolve over the course of generations through a process of natural selection, backed by a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The evidence was gathered on the Beagle expedition in the 1830s and the author’s subsequent findings from research, correspondence, and experimentation.

Nano Comes to Life opens a window onto the nanoscale - the infinitesimal realm of proteins and DNA where physics and cellular and molecular biology meet - and introduces listeners to the rapidly evolving nanotechnologies that are allowing us to manipulate the very building blocks of life. Sonia Contera gives an insider's perspective on this new frontier, revealing how nanotechnology enables a new kind of multidisciplinary science that is poised to give us control over our own biology, our health, and our lives.

We have lost the war on cancer. We spend $150 billion each year treating it, yet - a few innovations notwithstanding - a patient with cancer is as likely to die of it as one was 50 years ago. Most new drugs add mere months to one's life at agonizing physical and financial cost. In The First Cell, Azra Raza offers a searing account of how both medicine and our society (mis)treats cancer, how we can do better, and why we must.

First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive-making tools, for example, or using language - survived and flourished, replicating themselves in as many minds as possible.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

Of all the dietary and nutritional claims pitched to us, what can we believe? How does cinnamon affect your health? How splendid is Splenda? Should you buy farmed, wild, or canned food? What's fishy about fish-oil supplements? Will a diet of Twinkies and M&M's lead to weight loss? Water from a tap or from a plastic bottle - which should you choose, and which is better for the environment? Should you carry your groceries home in plastic or brown paper? We all have questions, and Dr. Joe Schwarcz has the answers, some of which will astonish you.

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.

In the best-selling, prize-winning A Short History of Nearly Everything Bill Bryson achieved the seemingly impossible by making the science of our world both understandable and entertaining to millions of people around the globe. Now he turns his attention inwards to explore the human body, how it functions and its remarkable ability to heal itself. Full of extraordinary facts and astonishing stories, The Body: A Guide for Occupants is a brilliant, often very funny attempt to understand the miracle of our physical and neurological makeup.

Comment à partir d'une toute petite cellule unique, est-il possible d'obtenir un organisme aussi complexe que celui d'un être vivant ? Par quel phénomène fascinant passe-t-on de l'embryon à l'Homme ? Ce sont ces interrogations qui ont accompagnées Nicole Le Douarin tout au long de son parcours scientifique. Cette grande biologiste française s'est notamment distinguée par ses travaux sur les chimères, ces êtres hybrides qu'elle a elle-même conçus en injectant des cellules de caille dans un embryon de poulet.

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.

Brigit Strawbridge Howard was shocked the day she realized she knew more about the French Revolution than she did about her native trees. And birds. And wildflowers. And bees. The thought stopped her — quite literally — in her tracks. But that day was also the start of a journey, one filled with silver birches and hairy-footed flower bees, skylarks, and rosebay willow herb, and the joy that comes with deepening one’s relationship with place.

We’re constantly seeking answers to these fundamental human questions, and now, science has the answers. The foods we enjoy, the people we love, the emotions we feel, and the beliefs we hold can all be traced back to our DNA, germs, and environment. This witty, colloquial book is popular science at its best, describing in everyday language how genetics, epigenetics, microbiology, and psychology work together to influence our personality and actions.

Microbiology for Dummies is your guide to understanding the fundamentals of this enormously-encompassing field. Whether your career plans include microbiology or another science or health specialty, you need to understand life at the cellular level before you can understand anything on the macro scale. Microbes are literally the foundation of all life, and they are everywhere. Microbiology for Dummies will help you understand them, appreciate them, and use them.

Naming Darwin's Black Box to the National Review's list of the 100 most important nonfiction works of the 20th century, George Gilder wrote that it "overthrows Darwin at the end of the 20th century in the same way that quantum theory overthrew Newton at the beginning". Discussing the book in the New Yorker in May 2005, H. Allen Orr said of Behe, "He is the most prominent of the small circle of scientists working on intelligent design, and his arguments are by far the best known."

David Quammen's book, The Song of the Dodo, is a brilliant, stirring work, breathtaking in its scope, far-reaching in its message - a crucial book in precarious times, which radically alters the way in which we understand the natural world and our place in that world. It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries.

Why was gin and tonic the cocktail of choice for British colonists in India and Africa? What does Starbucks have to thank for its global domination? What has protected the lives of popes for millennia? Why did Scotland surrender its sovereignty to England? What was George Washington's secret weapon during the American Revolution? The answer to all these questions, and many more, is the mosquito. Driven by surprising insights and fast-paced storytelling, The Mosquito is the extraordinary untold story of the mosquito’s reign through human history.

Perched on the exterior of our delicate and intricate bodies, the skin is our largest and fastest growing organ. We see it, touch it and live in it every day. It's a habitat for a mesmerisingly complex world of micro-organisms, its physical functions are vital to our health and indeed our survival, and it's crucial to our sense of identity. Yet how much do we really know about it? Through the lenses of science, sociology and history, Dr Monty Lyman leads us on a journey through the comedy, tragedy and exquisite humanity of our most underrated and overlooked organ.
