This text has invited more than 4 million students into the study of this dynamic and essential discipline.The authors have restructured each chapter around a conceptual framework of five or six big ideas. An Overview draws students in and sets the stage for the rest of the chapter, each numbered Concept Head announces the beginning of a new concept, and Concept Check questions at the end of each chapter encourage students to assess their mastery of a given concept. New Inquiry Figures focus students on the experimental process, and new Research Method Figures illustrate important techniques in biology. Each chapter ends with a Scientific Inquiry Question that asks students to apply scientific investigation skills to the content of the chapter.

    Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences.Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren't found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of Sao Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe.Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is.Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again.

    There really are no ultimate authority figures-no one has the secret and there is no place to look up the definitive answers to our questions (not even Google). But, by thinking skeptically and logically, we can combat sloppy reasoning, bad arguments and superstitious thinking. It's difficult, and takes a lot of vigilance, but it's worth the effort.In this tie-in to their incredibly popular "The Skeptics Guide to the Universe" podcast, Steven Novella, MD along with "Skeptical Rogues" Bob Novella, Cara Santa Maria, Jay Novella, and Evan Bernstein will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies and conspiracy theories (Anti-vaccines, homeopathy, UFO sightings, etc.) They'll help us try to make sense of what seems like an increasingly crazy world using powerful tools like science and philosophy. THE SKEPTICS' GUIDE TO THE UNIVERSE is your guide through this maze of modern life. It covers essential critical thinking skills, as well as giving insight into how your brain works and how to avoid common pitfalls in thinking. They discuss the difference between science and pseudoscience, how to recognize common science news tropes, how to discuss conspiracy theories with that crazy coworker of yours, and how to apply all of this to everyday life.So, are you ready to join them on an epic scientific quest, one that has taken us from huddling in dark caves to stepping foot on the Moon? (Yes, we really did that.) Like all adventures, this one is foremost a journey of self discovery. The monsters you will slay and challenges you will face are mostly constructs of your own mind. With the SKEPTIC'S GUIDE TO THE UNIVERSE, we can do this together.

    But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

    The result of thorough research, keen insight, and unassailable common sense, Good Calories, Bad Calories immediately stirred controversy and acclaim among academics, journalists, and writers alike. Michael Pollan heralded it as “a vitally important book, destined to change the way we think about food.” Building upon this critical work in Good Calories, Bad Calories and presenting fresh evidence for his claim, Taubes now revisits the urgent question of what’s making us fat—and how we can change—in this exciting new book. Persuasive, straightforward, and practical, Why We Get Fat makes Taubes’s crucial argument newly accessible to a wider audience.Taubes reveals the bad nutritional science of the last century, none more damaging or misguided than the “calories-in, calories-out” model of why we get fat, and the good science that has been ignored, especially regarding insulin’s regulation of our fat tissue. He also answers the most persistent questions: Why are some people thin and others fat? What roles do exercise and genetics play in our weight? What foods should we eat, and what foods should we avoid? Packed with essential information and concluding with an easy-to-follow diet, Why We Get Fat is an invaluable key in our understanding of an international epidemic and a guide to what each of us can do about it.

    Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. Those in cows and termites digest the plants they eat. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squids with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. I Contain Multitudes is the story of these extraordinary partnerships, between the creatures we are familiar with and those we are not. It reveals how we humans are disrupting these partnerships and how we might manipulate them for our own good. It will change both our view of nature and our sense of where we belong in it.

    An exposé of the psychiatric profession’s bible from a leading psychotherapist, The Book of Woe reveals the deeply flawed process by which mental disorders are invented and uninvented—and why increasing numbers of therapy patients are being declared mentally ill.

    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.

    It can be slipped into a drink, smeared onto the tip of an arrow or the handle of a door, even filtered through the air we breathe. But how exactly do these poisons work to break our bodies down, and what can we learn from the damage they inflict?In a blend of popular science, medical history, and true crime, Dr. Neil Bradbury explores the morbidly captivating method of murder from a cellular level. Alongside real-life accounts of murderers and their crimes—some notorious, some forgotten, some still unsolved—are the stories of the poisons involved: eleven molecules of death that work their way through the human body and, paradoxically, illuminate the way in which our bodies function.Drawn from historical records and current news headlines, A Taste for Poison weaves together the tales of spurned lovers, shady scientists, medical professionals and political assassins to show how the precise systems of the body can be impaired to lethal effect through the use of poison. From the deadly origins of the gin & tonic cocktail to the arsenic-laced wallpaper in Napoleon’s bedroom.

    When this classic work was first published in 1975, it created a new discipline and started a tumultuous round in the age-old nature versus nurture debate. Although voted by officers and fellows of the international Animal Behavior Society the most important book on animal behavior of all time, Sociobiology is probably more widely known as the object of bitter attacks by social scientists and other scholars who opposed its claim that human social behavior, indeed human nature, has a biological foundation. The controversy surrounding the publication of the book reverberates to the present day.In the introduction to this Twenty-Fifth Anniversary Edition, Edward O. Wilson shows how research in human genetics and neuroscience has strengthened the case for a biological understanding of human nature. Human sociobiology, now often called evolutionary psychology, has in the last quarter of a century emerged as its own field of study, drawing on theory and data from both biology and the social sciences.For its still fresh and beautifully illustrated descriptions of animal societies, and its importance as a crucial step forward in the understanding of human beings, this anniversary edition of Sociobiology: The New Synthesis will be welcomed by a new generation of students and scholars in all branches of learning.

    Weed. Bud. Whatever you choose to call it, it’s been a health aid, comfort, and life-enhancer for humankind for more than three thousand years. But while cannabis is used by hundreds of millions of people around the world, more than a century of prohibition has resulted in confusion about its status: Is it healthy? Is it medicinal? Will it make you crazy?In this fun, illuminating book, cannabis journalist Amanda Siebert delves deep into the latest research to separate marijuana fact from fiction, revealing ten evidence-based ways this potent little plant can improve your life. She speaks with some of the world’s top researchers, medical professionals, and consultants to answer questions such as: Can cannabis help you get a full night’s sleep? Does it aid in exercise and weight loss? Can it really cure cancer? She also offers practical advice for enjoying its benefits, including easy-to-follow, step-by-step instructions for consumption and dosage, as well as examples of real people who have used this drug to enhance their lives. Cannabis, it turns out, could be life-changing: it can enrich any diet, slow down aging, and even spice things up in the bedroom.

    For two decades, historian Alice Dreger has led a life of extraordinary engagement, combining activist service to victims of unethical medical research with defense of scientists whose work has outraged identity politics activists. With spirit and wit, Dreger offers in Galileo’s Middle Finger an unforgettable vision of the importance of rigorous truth seeking in today’s America, where both the free press and free scholarly inquiry struggle under dire economic and political threats.This illuminating chronicle begins with Dreger’s own research into the treatment of people born intersex (once called hermaphrodites). Realization of the shocking surgical and ethical abuses conducted in the name of “normalizing” intersex children’s gender identities moved Dreger to become an internationally recognized patient rights’ activist. But even as the intersex rights movement succeeded, Dreger began to realize how some fellow progressive activists were employing lies and personal attacks to silence scientists whose data revealed uncomfortable truths about humans. In researching one such case, Dreger suddenly became the target of just these kinds of attacks.Troubled, she decided to try to understand more—to travel the country to ferret out the truth behind various controversies, to obtain a global view of the nature and costs of these battles. Galileo’s Middle Finger describes Dreger’s long and harrowing journeys between the two camps for which she felt equal empathy: social justice activists determined to win and researchers determined to put hard truths before comfort. Ultimately what emerges is a lesson about the intertwining of justice and of truth—and a lesson of the importance of responsible scholars and journalists to our fragile democracy.
