But molecules, such as water and sugar, are not alive. So how do our cells--assemblies of otherwise "dead" molecules--come to life, and together constitute a living being? In "Life's Ratchet," physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. The complex molecules of our cells can rightfully be called "molecular machines," or "nanobots"; these machines, unlike any other, work autonomously to create order out of chaos. Tiny electrical motors turn electrical voltage into motion, tiny factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city--an unfathomable, complex collection of molecular worker bees working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. We are essentially giant assemblies of interacting nanoscale machines; machines more amazing than can be found in any science fiction novel. Incredibly, the molecular machines in our cells function without a mysterious "life force," nor do they violate any natural laws. Scientists can now prove that life is not supernatural, and that it can be fully understood in the context of science. Part history, part cutting-edge science, part philosophy, "Life's Ratchet" takes us from ancient Greece to the laboratories of modern nanotechnology to tell the story of our quest for the machinery of life.

    If you read one book on human origins, this should be it' Ian Morris, author of Why the West Rules - For Now 'The who, what, where, when and how of human evolution, from one of the world's experts on the dating of prehistoric fossils' Steve Brusatte, author of The Rise and Fall of the Dinosaurs50,000 years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements - in radiocarbon dating and ancient DNA, for example - that allowed each of these discoveries to be made, enabling us to be more accurate in our predictions about not just how long ago these other humans lived, but how they lived, interacted and live on in our genes today. This is the story of us, told for the first time with its full cast of characters.'The application of new genetic science to pre-history is analogous to how the telescope transformed astronomy. Tom Higham brings us to the frontier of recent discoveries with a book that is both gripping and fun' Paul Collier, author of The Bottom Billion'This exciting book shows that we now have a revolutionary new tool for reconstructing the human past: DNA from minute pieces of tooth and bone, and even from the dirt on the floor of caves' David Abulafia, author of The Boundless Sea'The remarkable new science of palaeoanthropology, from lab bench to trench' Rebecca Wragg Sykes, author of Kindred'Higham's thrilling account makes readers feel as if they were participating themselves in the extraordinary series of events that in the last few years has revealed our long-lost cousins' David Reich, author of Who We Are and How We Got Here'A brilliant distillation of the ideas and discoveries revolutionising our understanding of human evolution' Chris Gosden, author of The History of Magic

    This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human.In The Deep History of Ourselves LeDoux argues that the key to understanding all human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single cell organisms had to solve the same problems we and our cells have to solve today in order to survive and thrive. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enchanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

    The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity. Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his laboratory at Cornell and in the field in Uruguay, Australia, Panama, Europe and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs, this book makes readers participants in the grand adventure of discovery on a scale infinitesimally small and infinitely surprising.

    But if you cannot smell, does the rose lose its sweetness?The first and definitive book on the psychology of smell, The Scent of Desire traces the importance of smell in our lives, from nourishment to procreation to our relationships with the people closest to us and the world at large. Smell was the very first sense to evolve and is located in the same part of the brain that processes emotion, memory, and motivation. To our ancestors, the sense of smell wasn't just important, it was crucial to existence and it remains so today. Our emotional, physical, even sexual lives are profoundly shaped by both our reactions to and interpretations of different smells.Why do some people like a certain smell and others hate it? Is smell personal or cultural? How does smell affect our choices and our daily lives? Rachel Herz explores these questions and examines the role smell plays in our lives, and how this most essential of senses is imperative to our physical and emotional well-being. Herz investigates how our sense of smell functions, examines what purpose it serves, and shows how inextricably it is linked to our survival. She introduces us to people who have lost their ability to smell and shows how their experiences confirm this sense's importance by illuminating the traumatic effect its loss has on the quality of day-to-day living. Herz illustrates how profoundly scent and the sense of smell affect our daily lives with numerous examples and personal accounts based on her years of research.The wonders of our sense of smell are all explored in a compelling and engaging manner, from emotions and memory to aromatherapy and pheromones. For anyone who has ever wondered about human nature or been curious about the secrets of both the body and the mind, The Scent of Desire is a fascinating, down-to-earth tour of the psychology and biology of our most neglected sense, the sense of smell.

    The aim of a course in real analysis should be to challenge and improve mathematical intuition rather than to verify it. The philosophy of this book is to focus attention on questions which give analysis its inherent fascination.

    Mankind's battle to stay alive and healthy for as long as possible is our oldest, most universal struggle. With his characteristic wit and vastly informed historical scope, Roy Porter examines the war fought between disease and doctors on the battleground of the flesh from ancient times to the present. He explores the many ingenious ways in which we have attempted to overcome disease through the ages: the changing role of doctors, from ancient healers, apothecaries, and blood-letters to today's professionals; the array of drugs, from Ayurvedic remedies to the launch of Viagra; the advances in surgery, from amputations performed by barbers without anesthetic to today's sophisticated transplants; and the transformation of hospitals from Christian places of convalescence to modern medical powerhouses. Cleverly illustrated with historic line drawings, the chronic ailments of humanity provide vivid anecdotes for Porter's enlightening story of medicine's efforts to prevail over a formidable and ever-changing adversary.
