The challenge of scaling the highest mountain, exploring the deepest ocean, crossing the hottest desert, or swimming in near-freezing water is irresistible to many people. Life at the Extremes is an engrossing exploration of what happens to our bodies in these seemingly uninhabitable environments. Frances Ashcroft weaves stories of extraordinary feats of endurance with historical material and the latest scientific findings as she investigates the limits of human survival and the remarkable adaptations that enable us to withstand extreme conditions.What causes mountain sickness? How is it possible to reach the top of Everest without supplementary oxygen, when passengers in an airplane that depressurized at the same altitude would lose consciousness in seconds? Why do divers get the bends but sperm whales do not? How long you can survive immersion in freezing water? Why don't penguins get frostbite? Will men always be faster runners than women? How far into deep space can a body travel?As she considers these questions, Ashcroft introduces a cast of extraordinary scientific personalities—inventors and explorers who have charted the limits of human survival. She describes many intriguing experiments and shows how scientific knowledge has enabled us to venture toward and beyond ever greater limits. Life at the Extremes also considers what happens when athletes push their bodies to the edge, and tells of the remarkable adaptations that enable some organisms to live in boiling water, in highly acidic lakes, or deep in the middle of rocks.Anyone who flies in an airplane, sails the high seas, goes skiing or walking in the mountains, or simply weathers subzero winters or sweltering summers will be captivated by this book. Full of scientific information, beautifully written, and packed with many fascinating digressions, Life at the Extremes lures us to the very edge of human survival.

Ashcroft, Frances

Biological Sciences

University of California Pre

A lively exploration of the surprising role that electricity plays in our bodies. What happens during a heart attack? Can someone really die of fright? What is death, anyway? How does electroshock treatment affect the brain? What is consciousness? The answers to these questions lie in the electrical signals constantly traveling through our bodies, driving our thoughts, our movements, and even the beating of our hearts. The history of how scientists discovered the role of electricity in the human body is a colorful one, filled with extraordinary personalities, fierce debates, and brilliant experiments. Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric. 50 illustrations

We are all familiar with the idea that machines are powered by electricity, but perhaps not so aware that this is also true for ourselves. "The Spark of Life" is a spectacular account of the body electric, showing how, from before conception to the last breath we draw, electrical signals in our cells are essential to everything we think and do. These signals are produced by some amazing proteins that sit at the forefront of current scientific research - the ion channels. They are found in every cell in Earth and they govern every aspect of our lives, from consciousness to sexual attraction, fighting infection, our ability to see and hear, and the beating of our hearts. Ion channels are truly the 'spark of life'. Award-winning physiologist Frances Ashcroft weaves real-life stories with the latest scientific findings to explain the fundamental role of ion channels in our bodies. What happens when you have a heart attack? Why does an electric eel not shock itself? Can someone really die of fright? Why does Viagra turn the world blue? How do cocaine, LSD and morphine work? Why do chilli peppers taste hot? How do vampire bats sense their prey? Was Mary Shelley right when she inferred that electricity is the 'Spark of Life? Frances Ashcroft explains all this and more with wit and clarity. She introduces a cast of extraordinary personalities whose work has charted the links between molecule and mind over the centuries. She recounts the scientific detective stories involved in the development of our ideas about animal electricity, and shows how these are intimately entwined with our understanding of electricity itself. And she describes how the latest advances have led to the identification, and in some cases the cure, of a new class of disease. Anyone who has ever wondered about what makes us human will find this book a revelation.
