Book Description
Living with the Stars tells the fascinating story of what truly makes the human body. The body that is with us all our lives is always changing. We are quite literally not who we were years, weeks, or even days ago: our cells die and are replaced by new ones at an astonishing pace. The entire body continually rebuilds itself, time and again, using the food and water that flow through us as fuel and as construction material. What persists over time is not fixed but merely a pattern in flux. We rebuild using elements captured from our surroundings, and are thereby connected to animals and plants around us, and to the bacteria within us that help digest them, and to geological processes such as continental drift and volcanism here on Earth. We are also intimately linked to the Sun's nuclear furnace and to the solar wind, to collisions with asteroids and to the cycles of the birth of stars and their deaths in cataclysmic supernovae, and ultimately to the beginning of the universe. Our bodies are made of the burned out embers of stars that were released into the galaxy in massive explosions billions of years ago, mixed with atoms that formed only recently as ultrafast rays slammed into Earth's atmosphere. All of that is not just remote history but part of us now: our human body is inseparable from nature all around us and intertwined with the history of the universe.

Book Description
Whether you're a polar bear giving birth to cubs in an Arctic winter, a camel going days without water in the desert heat, or merely a suburbanite without air conditioning in a heat wave, your comfort and even survival depend on how well you adapt to extreme temperatures. In this entertaining and illuminating book, biopsychologist Mark Blumberg explores the many ways that temperature rules the lives of all animals (including us). He moves from the physical principles that govern the flow of heat in and out of our bodies to the many complex evolutionary devices animals use to exploit those principles for their own benefit. In the process Blumberg tells wonderful stories of evolutionary and scientific ingenuity--how penguins withstand Antarctic winters by huddling together by the thousands, how vulnerable embryos of many species are to extremes of temperature during their development, why people survive hour-long drowning accidents in winter but not in summer, how certain plants generate heat (the skunk cabbage enough to melt snow around it). We also hear of systems gone awry--how desert species given too much water can drink themselves into bloated immobility, why anorexics often complain of feeling cold, and why you can't sleep if the room is too hot or too cold. After reading this book, you'll never look at a thermostat in quite the same way again. Table of Contents: Introduction 1. Temperature: A User's Guide 2. Behave Yourself 3. Then Bake at 98.6°F for 400,000 Minutes 4. Everything in Its Place 5. Cold New World 6. Fever All through the Night 7. The Heat of Passion 8. Livin' off the Fat 9. The Light Goes Out Epilogue Bibliography Acknowledgments Index Reviews of this book: There's a little twinkle in Mark Blumberg's eye as he explains the role of temperature in life on Earth, that essential gleam that makes books about science successful and appealing...His writing is clear, a fine balance of explanation, example and ideas. --Susan Salter Reynolds, Los Angeles Times Book Review Reviews of this book: The need to maintain body temperature within a narrow range is the biggest single influence on physiology and behaviour, as Mark Blumberg explains in this little gem of a book, Body Heat...Blumberg describes the exquisite mechanisms developed by different species to generate, conserve or lose body heat. --John Bonner, New Scientist Reviews of this book: This is one of those books that leaves you for a few heady days in possession of a new key to all mysteries. Written entertainingly for a popular audience, the book argues that the evolved behaviour and physical characteristics of most creatures, from the tiniest nematode worm to the largest whale, is governed by the need to maintain a comfortable body temperature. --Emma Crichton-Miller, The Telegraph Reviews of this book: Blumberg...presents a thoroughly interesting book on body temperature and its many influences, loaded with a marvelously broad range of topics related to the biology of body temperature. From structural adaptations, such as ear size, circulatory patterns, and body shape that have evolved to help maintain body temperature, to psychological effects of temperature, the physiology of fevers, and even sexual-thermal metaphors used in everyday conversation. A host of fascinating aspects of how species respond to temperature changes are also discussed...Body Heat is great reading, certain to produce an enlightened appreciation for how body temperature control is critical for all organisms. --M. A. Palladino, Choice Reviews of this book: Mark S. Blumberg, in Body Heat, also takes the role of temperature in human affairs onto a global stage, but his metaphors, languages and conclusions are neither biblical nor prophetic. Instead he wants to remind us just how narrow our margins of tolerance are against that ultimate enemy: cold...Blumberg loves his subject, is convinced of its importance, and he wants to put across the intrinsic interest of temperature physiology to a larger audience. He retains a light touch--and because he is an active researcher in his own right, is able to bring new information and new insights to his pages. --Jonathan Kingdon, Times Literary Supplement This book is a real treat. Mark Blumberg takes something we normally hardly think about, and makes it into a fascinating topic, with colorful examples from fields as disparate as etymology and entomology. You probably will be repeating many of the stories he tells to those around you, as you discover why a fever may be good for you, or how babies generate their own heat, or how eating disorders interact with body temperature problems. It's entertaining, interesting, and great fun. --Michael Leon, University of California, Irvine This is an engaging enchilada of a book, wrapping up cold feet, a warm heart, hot sex, and chili peppers, for easy digestion by the general science consumer. Delicious! --Bernd Heinrich, University of Vermont, and author of The Hot-Blooded Insects: Strategies and Mechanisms of Thermoregulation

Book Description
For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made--up until this point, inadvertently--to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence. Without minimizing the challenges of the next century, Grinspoon suggests that our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective. Our species has surmounted the threat of extinction before, thanks to our innate ingenuity and ability to adapt, and there's every reason to believe we can do so again. Our challenge now is to awaken to our role as a force of planetary change, and to grow into this task. We must become graceful planetary engineers, conscious shapers of our environment and caretakers of Earth's biosphere. This is a perspective that begs us to ask not just what future do we want to avoid, but what do we seek to build? What kind of world do we want? Are humans the worst thing or the best thing to ever happen to our planet? Today we stand at a pivotal juncture, and the answer will depend on the choices we make.

Book Description
The acclaimed author of Einstein’s Dreams tackles "big questions like the origin of the universe and the nature of consciousness ... in an entertaining and easily digestible way” (Wall Street Journal) with a collection of meditative essays on the possibilities—and impossibilities—of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom The Washington Post has called “the poet laureate of science writers,” explores these questions and more—from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the Big Bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves.

Book Description
A New York Times-bestselling author explains how the physical world shaped the history of our species When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human. From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.
