Si todos debemos movernos para sobrevivir, vale la pena preguntarse: ¿qué factores de nuestro entorno nos impulsan a movernos y cuáles, por el contrario, nos detienen? ¿Por qué algunas personas tienen la oportunidad de moverse hacia donde quieren y otras no? ¿Por qué ciertas sociedades evolucionan y otras no? Para responder a estas interrogantes, los autores del libro estudiaron los códigos culturales y el comportamiento Bio-Lógico de 71 países para desarrollar un índice de que permite medir la movilidad social dentro de estas sociedades.Andrés Roemer y Clotaire Rapaille señalan que las culturas más exitosas son aquellas que han sabido preservar los mejores aspectos de su tradición, al mismo tiempo que han estado dispuestas a innovar y buscar nuevos horizontes. Se trata de sociedades abiertas al cambio y sin temor al statu quo. Otra clave del éxito evolutivo de las sociedades es el equilibrio entre el aspecto biológico (determinado por cuatro factores: supervivencia, sexo, seguridad y superación) y el aspecto cultural. El reto, concluyen los autores, es aprender a armonizar nuestros instintos (nuestro cerebro reptiliano) con nuestras emociones (nuestro cerebro límbico) y nuestra lógica (el neocórtex).ENGLISH DESCRIPTION If we all know we must move to survive, shouldn’t we ask ourselves which factors in our environment propel us and which halt us? Why do certain societies evolve while others don’t? In this book, Andrés Roemer and Clotaire Rapaille point out that the most successful cultures are those that are not afraid of the status quo: they have learned to preserve the best qualities of their traditions while being open to innovation and to uncovering new horizons. Another key to the success of these societies is the equilibrium between biological and the cultural aspects. The challenge is to harmonize our instincts, our emotions, and our logic.

    It presents positioning and projection information in an easy-to-read, bulleted format on one side of the page spread, with corresponding positioning photos, radiographic images and anatomical drawings on the other side. Expert content covers pathology, geriatric and pediatric patient populations, survey information, and 100 new positioning photographs for the latest in radiographic positioning. The 6th edition contains a new chapter on digital imaging, and digital imaging information is incorporated where appropriate throughout the book. New photographs and redrawn illustrations create a consistent, visual appearance throughout the book.- Characterized by a clear, easy-to-follow organization that features one projection per page. Positioning and projection information is presented in an easy-to-read bulleted format on the left side of the page, and positioning photos, radiographic images and anatomical drawings are aligned on the right. This show and tell style helps students visualize anatomy and understand positioning.- Includes about 200 of the most commonly requested projections. Competency in performing these projections is necessary for all entry-level practitioners. By contrast, Merrill's Atlas includes over 400 projections and much more information on advanced imaging.- Critique Radiographs provide the basis of classroom or lab discussion. The WB/LM contains questions specific to these radiographs.- Pathologic Indications in appropriate chapters - Introducing pathology with positioning helps students understand the whole patient and improves their ability to produce radiographs that make diagnosis easy for the physician.- Pediatric Applications in appropriate chapters prepare technologists to deal competently with the special needs of their pediatric patients.- Geriatric Applications in appropriate chapters - Important information for technologists to understand the varying needs of their patient base.- Alternative Modalities or procedures inform students of which projections can better demonstrate certain anatomical parts or pathology, or which may be necessary if patient is unable to cooperate fully.- Radiographic Criteria on positioning pages help students develop a routine for evaluating radiographic quality.- Pathology Demonstrated provides students with a larger frame of reference, and therefore a greater understanding, of each projectionA new chapter on digital imaging discusses basic principles, applications, and image quality - digital imaging information essential for making appropriate positioning adjustments - to ensure readers are prepared to encounter new technology in clinical practice.Content updates include a totally new section on surgical radiography, new sections in all chapters on digital imaging considerations, an expanded section on bone densitometry, and a new introduction to positron emission tomography (PET).Updated and revised chapters cover angiography and interventional procedures, and computed tomography.More than 150 new positioning photos, in addition to many updated images, complement the new material.

    But in Tomatoland, which is based on his James Beard Award-winning article, "The Price of Tomatoes," investigative food journalist Barry Estabrook reveals the huge human and environmental cost of the $5 billion fresh tomato industry. Fields are sprayed with more than one hundred different herbicides and pesticides. Tomatoes are picked hard and green and artificially gassed until their skins acquire a marketable hue. Modern plant breeding has tripled yields, but has also produced fruits with dramatically reduced amounts of calcium, vitamin A, and vitamin C, and tomatoes that have fourteen times more sodium than the tomatoes our parents enjoyed. The relentless drive for low costs has fostered a thriving modern-day slave trade in the United States. How have we come to this point?   Estabrook traces the supermarket tomato from its birthplace in the deserts of Peru to the impoverished town of Immokalee, Florida, a.k.a. the tomato capital of the United States. He visits the laboratories of seedsmen trying to develop varieties that can withstand the rigors of agribusiness and still taste like a garden tomato, and then moves on to commercial growers who operate on tens of thousands of acres, and eventually to a hillside field in Pennsylvania, where he meets an obsessed farmer who produces delectable tomatoes for the nation's top restaurants.Throughout Tomatoland, Estabrook presents a who's who cast of characters in the tomato industry: the avuncular octogenarian whose conglomerate grows one out of every eight tomatoes eaten in the United States; the ex-Marine who heads the group that dictates the size, color, and shape of every tomato shipped out of Florida; the U.S. attorney who has doggedly prosecuted human traffickers for the past decade; and the Guatemalan peasant who came north to earn money for his parents' medical bills and found himself enslaved for two years.Tomatoland reads like a suspenseful whodunit as well as an expose of today's agribusiness systems and the price we pay as a society when we take taste and thought out of our food purchases.

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation. Or, for that matter, whether flamingos are really real.

    The name dinosaur was coined in 1842 by an English anatomist Richard Owen, a highly ambitious, machiavellian schemer and villain of Deborah Cadbury's The Dinosaur Hunters: A True Story of Scientific Rivalry and the Discovery of the Prehistoric World. Her hero is Gideon Mantell, a practising doctor, who found and first described many of the bones of the beasts that subsequently became known as dinosaurs. Full of quotes from contemporary sources, The Dinosaur Hunters brilliantly evokes the Dickensian world of early Victorian science and society. From Mary Anning, the self-taught fossil hunter of Lyme Regis to the academic and deeply eccentric Dean Buckland of Oxford University, the story tells of reputations made and lost as self-help, self-promotion, over-wheening pride, folly and social climbing all played their part in the emerging story of the geological past. The dinosaurs, although central to the story, are also a vehicle for the much larger, more interesting and important story about the struggle to understand the meaning of fossils and what they tell us about prehistory. Deborah Cadbury, an award-winning TV science producer and acclaimed author of The Feminisation of Nature has thoroughly researched her topic and steeped herself in the intricacies of the scientific debates of the time. With black and white illustrations, extensive notes, a bibliography and index, the result is one of the best popular science histories. --Douglas Palmer.

    What they don't know is that without algae, none of us would exist. There are as many algae on Earth as stars in the universe, and they have been essential to life on our planet for eons. Algae created the Earth we know today, with its oxygen-rich atmosphere, abundant oceans, and coral reefs. Crude oil is made of dead algae, and algae are the ancestors of all plants. Today, seaweed production is a multi-billion dollar industry, with algae hard at work to make your sushi, chocolate milk, beer, paint, toothpaste, shampoo, and so much more. In Slime we'll meet the algae innovators working toward a sustainable future: from seaweed farmers in South Korea, to scientists using it to clean the dead zones in our waterways, to the entrepreneurs fighting to bring algae fuel and plastics to market. With a multitude of lively, surprising science and history, Ruth Kassinger takes listeners on an around-the-world, behind-the-scenes, and into-the-kitchen tour. Whether you thought algae was just the gunk in your fish tank or you eat seaweed with your oatmeal, Slime will delight and amaze with its stories of the good, the bad, and the up-and-coming.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    Details from cell structure and genetics, to immunology and pathogenicity, to taxonomy and phylogeny are covered. Also, based on recent taxonomic advances in RNA analysis, a new organization also makes this the first text to be divided by the three cell domains--Bacteria, Archaea, and Eukaryotes.

    

    If animals could talk, we would ask them to recall their own ancestries, in particular the secrets as to how they avoided almost inevitable annihilation in the face of daily assaults by predators, climactic cataclysms, deadly infections and innate diseases.In Tears of the Cheetah, medical geneticist and conservationist Stephen J. O'Brien narrates fast-moving science adventure stories that explore the mysteries of survival among the earth's most endangered and beloved wildlife. Here we uncover the secret histories of exotic species such as Indonesian orangutans, humpback whales, and the imperiled cheetah-the world's fastest animal which nonetheless cannot escape its own genetic weaknesses.Among these genetic detective stories we also discover how the Serengeti lions have lived with FIV (the feline version of HIV), where giant pandas really come from, how bold genetic action pulled the Florida panther from the edge of extinction, how the survivors of the medieval Black Death passed on a genetic gift to their descendents, and how mapping the genome of the domestic cat solved a murder case in Canada.With each riveting account of animal resilience and adaptation, a remarkable parallel in human medicine is drawn, adding yet another rationale for species conservation-mining their genomes for cures to our own fatal diseases. Tears of the Cheetah offers a fascinating glimpse of the insight gained when geneticists venutre into the wild.

    Mankind's battle to stay alive and healthy for as long as possible is our oldest, most universal struggle. With his characteristic wit and vastly informed historical scope, Roy Porter examines the war fought between disease and doctors on the battleground of the flesh from ancient times to the present. He explores the many ingenious ways in which we have attempted to overcome disease through the ages: the changing role of doctors, from ancient healers, apothecaries, and blood-letters to today's professionals; the array of drugs, from Ayurvedic remedies to the launch of Viagra; the advances in surgery, from amputations performed by barbers without anesthetic to today's sophisticated transplants; and the transformation of hospitals from Christian places of convalescence to modern medical powerhouses. Cleverly illustrated with historic line drawings, the chronic ailments of humanity provide vivid anecdotes for Porter's enlightening story of medicine's efforts to prevail over a formidable and ever-changing adversary.
