    He was a passionate Welsh patriot, but also an outspoken critic of his countrymen. His poems are an expression of his lifelong argument with himself, of his insistent search for God. In them he grapples with ideas of Welshness, with issues of technology, pollution, the decline of culture. He wrote too about love, about landscape, nature and birds. His is an urgent, prophetic and unique voice.

    He tells of the large science-steeped family who fostered his early fascination with chemistry. There follow his years at boarding school where, though unhappy, he developed the intellectual curiosity that would shape his later life. And we hear of his return to London, an emotionally bereft ten-year-old who found solace in his passion for learning. Uncle Tungsten radiates all the delight and wonder of a boy’s adventures, and is an unforgettable portrait of an extraordinary young mind.

    Each volume’s series editor selects notable works from hundreds of magazines, journals, and websites. A special guest editor, a leading writer in the field, then chooses the best twenty or so pieces to publish. This unique system has made the Best American series the most respected—and most popular—of its kind. The Best American Science and Nature Writing 2011 includes Atul Gawande, Jonathan Franzen, Deborah Blum, Malcolm Gladwell, Oliver Sacks, Jon Mooallem, Jon Cohen, Luke Dittrich, and others

    In this groundbreaking analysis, over thirty of the most popular treatments—acupuncture, homeopathy, aromatherapy, reflexology, chiropractic, and herbal medicines—are examined for their benefits and potential dangers. Questions answered include: What works and what doesn't? What are the secrets, and what are the lies? Who can you trust, and who is ripping you off? Can science decide what is best, or do the old wives' tales really tap into ancient, superior wisdom?In their scrutiny of alternative and complementary cures, authors Simon Singh and Edzard Ernst also strive to reassert the primacy of the scientific method as a means for determining public health practice and policy.

    Using his own research and experiences throughout the world, Lieberman recounts without jargon how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion.Exercised is entertaining and enlightening but also constructive. As our increasingly sedentary lifestyles have contributed to skyrocketing rates of obesity and diseases such as diabetes, Lieberman audaciously argues that to become more active we need to do more than medicalize and commodify exercise.Drawing on insights from evolutionary biology and anthropology, Lieberman suggests how we can make exercise more enjoyable, rather than shaming and blaming people for avoiding it. He also tackles the question of whether you can exercise too much, even as he explains why exercise can reduce our vulnerability to the diseases mostly likely to make us sick and kill us.

    In this book, Francisco J. Ayala—an evolutionary biologist, member of the National Academy of Sciences, and winner of the National Medal of Science and the Templeton Prize—cuts to the chase in a daring attempt to address, in nontechnical language, six perennial questions about evolution:• Am I a Monkey?• Why Is Evolution a Theory?• What Is DNA?• Do All Scientists Accept Evolution?• How Did Life Begin?• Can One Believe in Evolution and God?This to-the-point book answers each of these questions with force. Ayala's occasionally biting essays refuse to lend credence to disingenuous ideas and arguments. He lays out the basic science that underlies evolutionary theory, explains how the process works, and soundly makes the case for why evolution is not a threat to religion.Brief, incisive, topical, authoritative, Am I a Monkey? will take you a day to read and a lifetime to ponder.

    When temperatures drop below 56°F, tin crumbles into powder. Were the soldiers of the Grande Armée acutee fatally weakened by cold because the buttons of their uniforms fell apart? How different our world might be if tin did not disintegrate at low temperatures and the French had continued their eastward expansion! This fascinating book tells the stories of seventeen molecules that, like the tin of those buttons, greatly influenced the course of history. These molecules provided the impetus for early exploration and made possible the ensuing voyages of discovery. They resulted in grand feats of engineering and spurred advances in medicine; lie behind changes in gender roles, in law, and in the environment; and have determined what we today eat, drink, and wear. Showing how a change as small as the position of an atom can lead to enormous differences in the properties of a substance, the authors reveal the astonishing chemical connections among seemingly unrelated events. Napoleon's Buttons offers a novel way to understand how our contemporary world works and how our civilization has been shaped over time.

    In The Poisoner's Handbook Blum draws from highly original research to track the fascinating, perilous days when a pair of forensic scientists began their trailblazing chemical detective work, fighting to end an era when untraceable poisons offered an easy path to the perfect crime. Drama unfolds case by case as the heroes of The Poisoner's Handbook—chief medical examiner Charles Norris and toxicologist Alexander Gettler—investigate a family mysteriously stricken bald, Barnum and Bailey's Famous Blue Man, factory workers with crumbling bones, a diner serving poisoned pies, and many others. Each case presents a deadly new puzzle and Norris and Gettler work with a creativity that rivals that of the most imaginative murderer, creating revolutionary experiments to tease out even the wiliest compounds from human tissue. Yet in the tricky game of toxins, even science can't always be trusted, as proven when one of Gettler's experiments erroneously sets free a suburban housewife later nicknamed "America's Lucretia Borgia" to continue her nefarious work. From the vantage of Norris and Gettler's laboratory in the infamous Bellevue Hospital it becomes clear that killers aren't the only toxic threat to New Yorkers. Modern life has created a kind of poison playground, and danger lurks around every corner. Automobiles choke the city streets with carbon monoxide; potent compounds, such as morphine, can be found on store shelves in products ranging from pesticides to cosmetics. Prohibition incites a chemist's war between bootleggers and government chemists while in Gotham's crowded speakeasies each round of cocktails becomes a game of Russian roulette. Norris and Gettler triumph over seemingly unbeatable odds to become the pioneers of forensic chemistry and the gatekeepers of justice during a remarkably deadly time. A beguiling concoction that is equal parts true crime, twentieth-century history, and science thriller, The Poisoner's Handbook is a page-turning account of a forgotten New York.

    It's ever-present. Without it, you would die in minutes. And it has an epic story to tell.In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation.Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

    You might even be worried that these lapses in memory could be an early sign of Alzheimer's or dementia. In reality, for the vast majority of us, these examples of forgetting are completely normal. Why? Because while memory is amazing, it is far from perfect. Our brains aren't designed to remember every name we hear, plan we make, or day we experience. Just because your memory sometimes fails doesn't mean it's broken or succumbing to disease. Forgetting is actually part of being human. In Remember, neuroscientist and acclaimed novelist Lisa Genova delves into how memories are made and how we retrieve them. You'll learn whether forgotten memories are temporarily inaccessible or erased forever and why some memories are built to exist for only a few seconds (like a passcode) while others can last a lifetime (your wedding day). You'll come to appreciate the clear distinction between normal forgetting (where you parked your car) and forgetting due to Alzheimer's (that you own a car). And you'll see how memory is profoundly impacted by meaning, emotion, sleep, stress, and context. Once you understand the language of memory and how it functions, its incredible strengths and maddening weaknesses, its natural vulnerabilities and potential superpowers, you can both vastly improve your ability to remember and feel less rattled when you inevitably forget. You can set educated expectations for your memory, and in doing so, create a better relationship with it. You don't have to fear it anymore. And that can be life-changing.

    But as she began reading scholarly works in an attempt to grasp the microbiology, she quickly realized she couldn't do it alone. That’s why she went back to school in middle age, to study Ecology, Evolution, and Environmental Biology at Columbia University. Her college experience was in equal parts challenging, humbling, and hilarious. The material was daunting, not only because she had spent her life convinced it was beyond her comprehension (a conviction many people share about science), but also because microbes are so different from the organisms we can see. She initially found it difficult to understand creatures that evolve so fast they can become another species in a matter of weeks, that can share genes by touching, that bridge the nonliving and living spheres of life. But despite her academic trials, Bone realized all life, from a mushroom to a maestro, are microbial in essence. Indeed, life itself is a vast conspiracy of microbes.This popular science book takes the layman on a broad survey of the role of microbes in nature and shows how different the world is with a microbial point of view.
