And certainly no one wants to overeat for years, become overweight, and end up with a high risk of diabetes or heart disease--yet two thirds of Americans do precisely that. Even though we know better, we often eat too much. Why does our behavior betray our own intentions to be lean and healthy? The problem, argues obesity and neuroscience researcher Stephan J. Guyenet, is not necessarily a lack of willpower or an incorrect understanding of what to eat. Rather, our appetites and food choices are led astray by ancient, instinctive brain circuits that play by the rules of a survival game that no longer exists. And these circuits don’t care about how you look in a bathing suit next summer.To make the case, The Hungry Brain takes readers on an eye-opening journey through cutting-edge neuroscience that has never before been available to a general audience. The Hungry Brain delivers profound insights into why the brain undermines our weight goals and transforms these insights into practical guidelines for eating well and staying slim. Along the way, it explores how the human brain works, revealing how this mysterious organ makes us who we are.

    Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: he starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.And so the first category of explanation is the neurobiological one. A behavior occurs--whether an example of humans at our best, worst, or somewhere in between. What went on in a person's brain a second before the behavior happened? Then Sapolsky pulls out to a slightly larger field of vision, a little earlier in time: What sight, sound, or smell caused the nervous system to produce that behavior? And then, what hormones acted hours to days earlier to change how responsive that individual is to the stimuli that triggered the nervous system? By now he has increased our field of vision so that we are thinking about neurobiology and the sensory world of our environment and endocrinology in trying to explain what happened.Sapolsky keeps going: How was that behavior influenced by structural changes in the nervous system over the preceding months, by that person's adolescence, childhood, fetal life, and then back to his or her genetic makeup? Finally, he expands the view to encompass factors larger than one individual. How did culture shape that individual's group, what ecological factors millennia old formed that culture? And on and on, back to evolutionary factors millions of years old.The result is one of the most dazzling tours d'horizon of the science of human behavior ever attempted, a majestic synthesis that harvests cutting-edge research across a range of disciplines to provide a subtle and nuanced perspective on why we ultimately do the things we do...for good and for ill. Sapolsky builds on this understanding to wrestle with some of our deepest and thorniest questions relating to tribalism and xenophobia, hierarchy and competition, morality and free will, and war and peace. Wise, humane, often very funny, Behave is a towering achievement, powerfully humanizing, and downright heroic in its own right.

    In Darwin Comes to Town, evolutionary biologist Menno Schilthuizen shows that evolution can in fact happen extremely quickly, and in the strangest of places: the heart of the city.Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating the evolution of the animals and plants around us. Cities are extreme environments and, in a world of adapt or die, the wildlife sharing these spaces with us is being forced to adopt fascinating new ways of surviving, and often thriving.--Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts.--Spiders in Vienna are adapting to build their webs near moth-attracting streetlights, while moths in some cities are developing a resistance to the lure of light bulbs.--Certain Puerto Rican city lizards are evolving feet that better grip surfaces like concrete.--Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heard over the din of traffic, while many pigeons have eschewed traveling “as the crow flies” in favor of following manmade roads.Darwin Comes to Town draws on these and other eye-popping examples to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward overpopulation might not take the rest of nature down with us.

    By weaving together their own research, interviews with pioneering scientists and Zach's trademark comics, the Weinersmiths investigate why these innovations are needed, how they would work, and what is standing in their way.

    Chanda Prescod-Weinstein shares her love for physics, from the Standard Model of Particle Physics and what lies beyond it, to the physics of melanin in skin, to the latest theories of dark matter — all with a new spin informed by history, politics, and the wisdom of Star Trek.One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly non-traditional, and grounded in Black feminist traditions.Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, sexism, and other dehumanizing systems. She lays out a bold new approach to science and society that begins with the belief that we all have a fundamental right to know and love the night sky. The Disordered Cosmos dreams into existence a world that allows everyone to tap into humanity’s wealth of knowledge about the wonders of the universe.

    In biology labs across the world, fruit flies are turning up answers to some of the basic questions of life. It's business as usual for the fly, which for generations has been defining biology's major landmarks. From genetics to development, behavior to aging, and evolution to the origin of species, the fruit fly has been a key player in some of the twentieth century's greatest biological discoveries.Techniques to pinpoint genes that play a role in human disease depend on genetic mapmaking principles first established with the fly. It was experiments on fruit flies that opened our eyes to the dangers of radiation to human health. In fact, everything from gene therapy to cloning to the Human Genome Project is built on the foundation of fruit fly research. Despite its many achievements, the fruit fly remains an unsung hero in the history of science. At last, here is a book that gives the fly its long overdue credit.In a highly original, witty, and irreverent style, Martin Brookes takes us through successive stages in the life cycle of the fly, each illustrating an important concept in biology. Some, such as the fundamentals of heredity, are well established; others, such as sexual warfare, learning, and memory, are still in their infancy. But whether flies are getting high on crack cocaine, enjoying the pleasures and pains of a boozy night out, being trained by punishment and reward, or struggling with insomnia, this book provides a glimpse of how one short life has informed almost every aspect of human existence. The result is a broad introduction to biology with insights into the practical realities of science.Often dismissed as irrelevant outside academic circles, the fruit fly, through this distinctive biography, will come to be recognized for what it really is: an icon of twentieth-century science and a window on our own biological world.

    And yet, until very recently, scientists believed our brains were fully developed from childhood on. Now, thanks to imaging technology that enables us to look inside the living human brain at all ages, we know that this isn't so. Professor Sarah-Jayne Blakemore, one of the world's leading researchers into adolescent neurology, explains precisely what is going on in the complex and fascinating brains of teenagers--namely that the brain goes on developing and changing right through adolescence--with profound implications for the adults these young people will become.Drawing from cutting-edge research, including her own, Blakemore shows:How an adolescent brain differs from those of children and adultsWhy problem-free kids can turn into challenging teensWhat drives the excessive risk-taking and all-consuming relationships common among teenagersAnd why many mental illnesses--depression, addiction, schizophrenia--present during these formative yearsBlakemore's discoveries have transformed our understanding of the teenage mind, with consequences for law, education policy and practice, and, most of all, parents.

    Pigeons have been worshipped as fertility goddesses and used as crucial communicators in war by every major historical superpower from ancient Egypt to the United States, saving thousands of lives. Yet, without just cause, they are reviled today as “rats of the sky.” How did we come to misunderstand one of mankind’s most helpful and steadfast companions? Author Andrew D. Blechman traveled across the United States and Europe to meet with pigeon fanciers and pigeon haters in a quest to chronicle the pigeon’s transformation from beloved friend to feathered outlaw. Pigeons captures a Brooklyn man’s quest to win the Main Event (the pigeon world’s equivalent of the Kentucky Derby), as well as a pigeon shoot where entrants pay $150 to shoot live pigeons. Blechman tracks down Mike Tyson, the nation’s most famous pigeon lover, and he sheds light on a radical “pro-pigeon underground” in New York City. In Pigeons , Blechman tells for the first time the remarkable story behind this seemingly unremarkable bird.

    Chemistry professor and syndicated Washington Post food columnist Robert L. Wolke provides over 100 reliable and witty explanations, while debunking misconceptions and helping you to see through confusing advertising and labeling.

    But what happens when we take animal alteration a step further, engineering a cat that glows green under ultraviolet light or cloning the beloved family Labrador? Science has given us a whole new toolbox for tinkering with life. How are we using it?In Frankenstein's Cat, the journalist Emily Anthes takes us from petri dish to pet store as she explores how biotechnology is shaping the future of our furry and feathered friends. As she ventures from bucolic barnyards to a "frozen zoo" where scientists are storing DNA from the planet's most exotic creatures, she discovers how we can use cloning to protect endangered species, craft prosthetics to save injured animals, and employ genetic engineering to supply farms with disease-resistant livestock. Along the way, we meet some of the animals that are ushering in this astonishing age of enhancement, including sensor-wearing seals, cyborg beetles, a bionic bulldog, and the world's first cloned cat.Through her encounters with scientists, conservationists, ethicists, and entrepreneurs, Anthes reveals that while some of our interventions may be trivial (behold: the GloFish), others could improve the lives of many species-including our own. So what does biotechnology really mean for the world's wild things? And what do our brave new beasts tell us about ourselves?With keen insight and her trademark spunk, Anthes highlights both the peril and the promise of our scientific superpowers, taking us on an adventure into a world where our grandest science fiction fantasies are fast becoming reality.

    They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one. How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions, revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility, sexual development—potentially including the increase in gender fluidity—and general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies, Count Down is “staggering in its findings” (Erin Brockovich, The Guardian) and “will serve as an awakening” (The New York Times Book Review).

    Mara Altman's volatile and apprehensive relationship with her body has led her to wonder about a lot of stuff over the years. Like, who decided that women shouldn't have body hair? And how sweaty is too sweaty? Also, why is breast cleavage sexy but camel toe revolting? Isn't it all just cleavage? These questions and others like them have led to the comforting and sometimes smelly revelations that constitute Gross Anatomy, an essay collection about what it's like to operate the bags of meat we call our bodies.Divided into two sections, "The Top Half" and "The Bottom Half," with cartoons scattered throughout, Altman's book takes the reader on a wild and relatable journey from head to toe—as she attempts to strike up a peace accord with our grody bits.With a combination of personal anecdotes and fascinating research, Gross Anatomy holds up a magnifying glass to our beliefs, practices, biases, and body parts and shows us the naked truth: that there is greatness in our grossness.

    

    The renowned biologist Daniel Chamovitz builds on the original edition to present an intriguing look at how plants themselves experience the world—from the colors they see to the schedules they keep, and now, what they do in fact hear and how they are able to taste. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers a greater understanding of their place in nature.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.
