These are the very same behaviors that typify good soldiering and foster a sense of belonging among troops, whether they’re fighting on the front lines or engaged in non-combat activities away from the action. Drawing from history, psychology, and anthropology, bestselling author Sebastian Junger shows us just how at odds the structure of modern society is with our tribal instincts, arguing that the difficulties many veterans face upon returning home from war do not stem entirely from the trauma they’ve suffered, but also from the individualist societies they must reintegrate into.A 2011 study by the Canadian Forces and Statistics Canada reveals that 78 percent of military suicides from 1972 to the end of 2006 involved veterans. Though these numbers present an implicit call to action, the government is only just taking steps now to address the problems veterans face when they return home. But can the government ever truly eliminate the challenges faced by returning veterans? Or is the problem deeper, woven into the very fabric of our modern existence? Perhaps our circumstances are not so bleak, and simply understanding that beneath our modern guises we all belong to one tribe or another would help us face not just the problems of our nation but of our individual lives as well.Well-researched and compellingly written, this timely look at how veterans react to coming home will reconceive our approach to veteran’s affairs and help us to repair our current social dynamic.

    Indeed, these tiny structures inside our cells are important beyond imagining. Without mitochondria, we would have no cell suicide, no sculpting of embryonic shape, no sexes, no menopause, no aging.In this fascinating and thought-provoking book, Nick Lane brings together the latest research in this exciting field to show how our growing insight into mitochondria has shed light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. These findings are of fundamental importance, both in understanding life on Earth, but also in controlling our own illnesses, and delaying our degeneration and death. Readers learn that two billion years ago, mitochondria were probably bacteria living independent lives and that their capture within larger cells was a turning point in the evolution of life, enabling the development of complex organisms. Lane describes how mitochondria have their own DNA and that its genes mutate much faster than those in the nucleus. This high mutation rate lies behind our aging and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer. We also discover that mitochondrial DNA is passed down almost exclusively via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to "Mitochondrial Eve," giving us vital information about our evolutionary history.Written by Nick Lane, a rising star in popular science, Power, Sex, Suicide is the first book for general readers on the nature and function of these tiny, yet fascinating structures.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.

    Through a series of entertaining, bite-sized chapters that combine anthropological insight with cutting-edge science, we gain fresh perspectives into our first hominin ancestors and ways to challenge perceptions about the traditional progression of evolution. With Lee as our guide, we discover that we indeed have always been a species of continuous change.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. Our scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers.Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly—some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it.Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    It was in search of the fabled Spice Islands and their cloves that Magellan charted the first circumnavigation of the globe. Vasco da Gama sailed the dangerous waters around Africa to India on a quest for Christians--and spices. Columbus sought gold and pepper but found the New World. By the time these fifteenth- and sixteenth-century explorers set sail, the aromas of these savory, seductive seeds and powders had tempted the palates and imaginations of Europe for centuries. "Spice: The History of a Temptation "is a history of the spice trade told not in the conventional narrative of politics and economics, nor of conquest and colonization, but through the intimate human impulses that inspired and drove it. Here is an exploration of the centuries-old desire for spice in food, in medicine, in magic, in religion, and in sex--and of the allure of forbidden fruit lingering in the scents of cinnamon, pepper, ginger, nutmeg, mace, and clove. We follow spices back through time, through history, myth, archaeology, and literature. We see spices in all their diversity, lauded as love potions and aphrodisiacs, as panaceas and defenses against the plague. We journey from religious rituals in which spices were employed to dispel demons and summon gods to prodigies of gluttony both fantastical and real. We see spices as a luxury for a medieval king's ostentation, as a mummy's deodorant, as the last word in haute cuisine. Through examining the temptations of spice we follow in the trails of the spice seekers leading from the deserts of ancient Syria to thrill-seekers on the Internet. We discover howspice became one of the first and most enduring links between Asia and Europe. We see in the pepper we use so casually the relic of a tradition linking us to the appetites of Rome, Elizabethan England, and the pharaohs. And we capture the pleasure of spice not only at the table but in every part of life. "Spice "is a delight to be savored.

    These three Great Untruths are part of a larger philosophy that sees young people as fragile creatures who must be protected and supervised by adults. But despite the good intentions of the adults who impart them, the Great Untruths are harming kids by teaching them the opposite of ancient wisdom and the opposite of modern psychological findings on grit, growth, and antifragility. The result is rising rates of depression and anxiety, along with endless stories of college campuses torn apart by moralistic divisions and mutual recriminations. This is a book about how we got here. First Amendment expert Greg Lukianoff and social psychologist Jonathan Haidt take us on a tour of the social trends stretching back to the 1980s that have produced the confusion and conflict on campus today, including the loss of unsupervised play time and the birth of social media, all during a time of rising political polarization. This is a book about how to fix the mess. The culture of “safety” and its intolerance of opposing viewpoints has left many young people anxious and unprepared for adult life, with devastating consequences for them, for their parents, for the companies that will soon hire them, and for a democracy that is already pushed to the brink of violence over its growing political divisions. Lukianoff and Haidt offer a comprehensive set of reforms that will strengthen young people and institutions, allowing us all to reap the benefits of diversity, including viewpoint diversity. This is a book for anyone who is confused by what’s happening on college campuses today, or has children, or is concerned about the growing inability of Americans to live and work and cooperate across party lines.

    Once he started a family, the moral dimensions of food became increasingly important.Faced with the prospect of being unable to explain why we eat some animals and not others, Foer set out to explore the origins of many eating traditions and the fictions involved with creating them. Traveling to the darkest corners of our dining habits, Foer raises the unspoken question behind every fish we eat, every chicken we fry, and every burger we grill.Part memoir and part investigative report, Eating Animals is a book that, in the words of the Los Angeles Times, places Jonathan Safran Foer "at the table with our greatest philosophers."

    As we reel from the latest horror . . . " So begins a new epilogue, illustrating how Columbine became the template for nearly two decades of "spectacle murders." It is a false script, seized upon by a generation of new killers. In the wake of Newtown, Aurora, and Virginia Tech, the imperative to understand the crime that sparked this plague grows more urgent every year.What really happened April 20, 1999? The horror left an indelible stamp on the American psyche, but most of what we "know" is wrong. It wasn't about jocks, Goths, or the Trench Coat Mafia. Dave Cullen was one of the first reporters on scene, and spent ten years on this book-widely recognized as the definitive account. With a keen investigative eye and psychological acumen, he draws on mountains of evidence, insight from the world's leading forensic psychologists, and the killers' own words and drawings-several reproduced in a new appendix. Cullen paints raw portraits of two polar opposite killers. They contrast starkly with the flashes of resilience and redemption among the survivors.

    As the mosquito transformed the landscapes of civilization, humans were unwittingly required to respond to its piercing impact and universal projection of power.The mosquito has determined the fates of empires and nations, razed and crippled economies, and decided the outcome of pivotal wars, killing nearly half of humanity along the way. She (only females bite) has dispatched an estimated 52 billion people from a total of 108 billion throughout our relatively brief existence. As the greatest purveyor of extermination we have ever known, she has played a greater role in shaping our human story than any other living thing with which we share our global village.Imagine for a moment a world without deadly mosquitoes, or any mosquitoes, for that matter? Our history and the world we know, or think we know, would be completely unrecognizable.Driven by surprising insights and fast-paced storytelling, The Mosquito is the extraordinary untold story of the mosquito's reign through human history and her indelible impact on our modern world order.

    He explores the history of places, like Vienna of 1900, Renaissance Florence, ancient Athens, Song Dynasty Hangzhou, and Silicon Valley, to show how certain urban settings are conducive to ingenuity. And, with his trademark insightful humor, he walks the same paths as the geniuses who flourished in these settings to see if the spirit of what inspired figures like Socrates, Michelangelo, and Leonardo remains. In these places, Weiner asks, “What was in the air, and can we bottle it?”
