The range of environments in which people can survive is extensive, yet most of the natural world cannot support human life. The Biology of Human Survival identifies the key determinants of life or death in extreme environments from a physiologist's perspective, integrating modern concepts of stress, tolerance, and adaptation into explanations of life under Nature's most austere conditions. The book examines how individuals survive when faced with extremes of immersion, heat, cold or altitude, emphasizing the body's recognition of stress and the brain's role in optimizing physiological function in order to provide time to escape or to adapt. In illustrating how human biology adapts to extremes, the book also explains how we learn to cope by blending behavior and biology, first by trial and error, then by rigorous scientific observation, and finally by technological innovation. The book describes life-support technology and how it enables humans to enter once unendurable realm, from the depths of the ocean to the upper reaches of the atmosphere and beyond. Finally, it explores the role that advanced technology might play in special environments of the future, such as long journeys into space.

A Publishers Weekly Best Book of 2014 This revelatory tour de force by an acclaimed and internationally bestselling science writer upends our understanding of “survival of the fittest”—and invites us all to think and act more altruistically The phrase “survival of the fittest” conjures an image of the most cutthroat individuals rising to the top. But Stefan Klein, author of the #1 international bestseller The Science of Happiness, makes the startling assertion that altruism is the key to lasting personal and societal success. In fact, altruism defines us: Natural selection favored those early humans who cooperated in groups, and with survival more assured, our altruistic ancestors were free to devote brainpower to developing intelligence, language, and culture—our very humanity. Klein’s groundbreaking findings lead him to a vexing question: If we’re really hard-wired to act for one another’s benefit, why aren’t we all getting along? He believes we’ve learned to mistrust our instincts because success is so often attributed to selfish ambition, and with an extraordinary array of material—current research on genetics and the brain, economics, social psychology, behavioral and anthropological experiments, history, and modern culture—he makes the case that generosity for its own sake remains the best way to thrive.

'The peacock's tail makes me sick!' said Charles Darwin. That's because the theory of evolution as adaptation can't explain why nature is so beautiful. It took the concept of sexual selection for Darwin to explain that, a process that has more to do with aesthetic taste than adaptive fitness. Survival of the Beautiful is a revolutionary new examination of the interplay of beauty, art, and culture in evolution. Taking inspiration from Darwin's observation that animals have a natural aesthetic sense, philosopher and musician David Rothenberg probes why animals, humans included, have an innate appreciation for beauty - and why nature is, indeed, beautiful.

Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted book offers a new, holistic way of thinking about energy and water—a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure the continuing sustainability of both. Michael Webber, a leader and teacher in the field of energy technology and policy, explains how energy and water supplies are linked and how problems in either can be crippling for the other. He shows that current population growth, economic growth, climate change, and short-sighted policies are likely to make things worse. Yet, Webber asserts, more integrated planning with long-term sustainability in mind can avert such a daunting future. Combining anecdotes and personal stories with insights into the latest science of energy and water, he identifies a hopeful path toward wise long-range water-energy decisions and a more reliable and abundant future for humanity.

Seeking to reenergize Americans' passion for the space program, the value of further exploration of the Moon, and the importance of human beings on the final frontier, Claude A. Piantadosi presents a rich history of American space exploration and its major achievements. He emphasizes the importance of reclaiming national command of our manned program and continuing our unmanned space missions, and he stresses the many adventures that still await us in the unfolding universe. Acknowledging space exploration's practical and financial obstacles, Piantadosi challenges us to revitalize American leadership in space exploration in order to reap its scientific bounty. Piantadosi explains why space exploration, a captivating story of ambition, invention, and discovery, is also increasingly difficult and why space experts always seem to disagree. He argues that the future of the space program requires merging the practicalities of exploration with the constraints of human biology. Space science deals with the unknown, and the margin (and budget) for error is small. Lethal near-vacuum conditions, deadly cosmic radiation, microgravity, vast distances, and highly scattered resources remain immense physical problems. To forge ahead, America needs to develop affordable space transportation and flexible exploration strategies based in sound science. Piantadosi closes with suggestions for accomplishing these goals, combining his healthy skepticism as a scientist with an unshakable belief in space's untapped—and wholly worthwhile—potential.

From the first unicellular life on Earth, living things have had the capacity tosense heat and cold and to avoid extreme temperatures. With the development of a bigger brain and aconstant body temperature, mammals were able to change their habitats. The interplay betweenbehavior, body temperature, and ambient temperature may have played a crucial role in humanevolution. In this book Carl Gisolfi and Francisco Mora tell the evolutionary story of the brain andthermoregulation, with an emphasis on modern humans. The book first traces thestory of the brain throughout evolution and shows how the control of body temperature as a survivalmechanism was achieved. It then goes on to discuss the mechanisms of our environmental independence,why a body temperature of 37° C (only five degrees from death) is essential for humans and howthis narrow temperature range is defended. It describes how we cope with environmental extremes, thefunction of fevers, and why thermoregulation is best understood through a combination ofphysiological and cognitive approaches. It also addresses such questions as "Can we cool the brain?"and "Is the elevation in brain temperature (a hot brain) the reason we stop exercising?"

In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How? As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference. It’s a frightening prospect, as each of the Earth’s past major disasters—from meteor strikes to bombardment by cosmic radiation—resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation—humans have, more than once, narrowly avoided extinction just during the last million years—but every single time a few creatures survived, evolving to adapt to the harshest of conditions. This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death. Newitz’s remarkable and fascinating journey through the science of mass extinctions is a powerful argument about human ingenuity and our ability to change. In a world populated by doomsday preppers and media commentators obsessively forecasting our demise, Scatter, Adapt, and Remember is a compelling voice of hope. It leads us away from apocalyptic thinking into a future where we live to build a better world—on this planet and perhaps on others. Readers of this book will be equipped scientifically, intellectually, and emotionally to face whatever the future holds.
