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.

    Millions of children are busy with projects to save the Earth. But we all would be more effective at resolving today's pressing environmental issues if we had a clearer understanding of the ecological principles behind them. With this lively guide to the essentials of ecology, Ernest Callenbach provides a pocket-sized introduction to the wonderful complexity of life on Earth—and our part in it.Callenbach uses everyday, nontechnical language to explain sixty basic ecological concepts. These brief, information-packed entries are arranged alphabetically and amply cross-referenced. Thus the reader can move freely around a dynamic network of ideas, gaining easy access to the new thinking that scientists, environmentalists, politicians, government officials, business people, and concerned citizens everywhere are using to seek a sustainable future for humanity.As timely as today's news, Ecology includes current findings on the microscopic beings that first made plant and animal life possible and now regulate global temperature and oxygen levels—a dramatic new story of the intricate interconnections of all life on Earth. Finally we have a book that equips us to take informed personal and political action with the ecological wisdom needed for the twenty-first century.

    A spellbinding look into the natural world's most fascinating and baffling phenomena, with illustrated explanations of rainbows, meteors, sunsets, hurricanes, the northern lights, and dozens of other curiosities of the sky.

    He travels east in search of his brother, moving on foot against the great push to the west. Driven back over and over again on his journey through vast expanses, Håkan meets naturalists, criminals, religious fanatics, Indians, and lawmen, and his exploits turn him into a legend. Díaz defies the conventions of historical fiction and genre (travel narratives, the bildungsroman, nature writing, the Western), offering a probing look at the stereotypes that populate our past and a portrait of radical foreignness.At first, it was a contest, but in time the beasts understood that, with an embrace and the slightest push, they had to lie down on their side and stay until Håkan got up. He did this each time he thought he spied someone on the circular horizon. Had Håkan and his animals ever been spotted, the distant travelers would have taken the vanishing silhouettes for a mirage. But there were no such travelers—the moving shadows he saw almost every day in the distance were illusions. With the double intention of getting away from the trail and the cold, he had traveled south for days.Hernán Díaz is the author of Borges, Between History and Eternity (Bloomsbury 2012), managing editor of RHM, and associate director of the Hispanic Institute at Columbia University. He lives in New York.

    Tirelessly trekking across miles of the Thames’ muddy shores, where others only see the detritus of city life, Maiklem unearths evidence of England’s captivating, if sometimes murky, history—with some objects dating back to 43 AD, when London was but an outpost of the Roman Empire. From medieval mail worn by warriors on English battlefields to nineteenth-century glass marbles mass-produced for the nation’s first soda bottles, Maiklem deduces the historical significance of these artifacts with the quirky enthusiasm and sharp-sightedness of a twenty-first century Sherlock Holmes.Seamlessly interweaving reflections from her own life with meditations on the art of wandering, Maiklem ultimately delivers—for Anglophiles and history lovers alike—a memorable treatise on the objects we leave in our wake, and the stories they can reveal if only we take a moment to look.

    Illustrated throughout with detailed photographs and illustrations, and using clear, easy-to-follow text, The Practical Astronomer takes you on a step-by-step journey from the basics of what can be seen with the naked eye, to how you can view more distant objects such as the planets of the solar system, and even galaxies far, far away-all in your own backyard.

    Soon the Camp Fire was upon them, gobbling an acre a second. Less than two hours after it ignited, residents were trapped in flames, cremated in their homes and cars. By the next morning, eighty-five people were dead.San Francisco Chronicle reporter Lizzie Johnson was there as the town of Paradise burned. She saw the smoldering rubble of a historic covered bridge and the beloved Black Bear Diner, and she stayed long afterward, visiting shelters, hotels, and makeshift camps. Drawing on years of on-the-ground reporting and reams of public records, including 911 calls and testimony from a grand jury investigation, Johnson provides a minute-by-minute account of the Camp Fire, following residents and first responders as they fight to save themselves and their town. We see a young mother fleeing with her newborn; a school bus full of children in search of an escape route; and a group of paramedics, patients, and nurses trapped in a cul-de-sac, fending off the fire with rakes and hoses.Johnson documents the unfolding tragedy with empathy and nuance. But she also investigates the root causes, from runaway climate change to a deeply flawed alert system to Pacific Gas and Electric's decades-long neglect of critical infrastructure. A cautionary tale for a new era of megafires, Paradise is the gripping story of a town wiped off the map and the determination of its people to rise again.

    Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders.

    How has the climate changed in the past?How is it changing now?How do we know?And what kind of a future do we want to create?

    After months of grueling travel, the 81 men, women and children would be trapped for a brutal winter with little food and only primitive shelter. The conclusion is known: by spring of the next year, the Donner Party was synonymous with the most harrowing extremes of human survival. But until now, the full story of what happened, what it tells us about human nature and about America's westward expansion, remained shrouded in myth.Drawing on fresh archaeological evidence, recent research on topics ranging from survival rates to snowfall totals, and heartbreaking letters and diaries made public by descendants a century-and-a-half after the tragedy, Ethan Rarick offers an intimate portrait of the Donner party and their unimaginable ordeal: a mother who must divide her family, a little girl who shines with courage, a devoted wife who refuses to abandon her husband, a man who risks his life merely to keep his word. But Rarick resists both the gruesomely sensationalist accounts of the Donner party as well as later attempts to turn the survivors into archetypal pioneer heroes. The Donner Party, Rarick writes, is a story of hard decisions that were neither heroic nor villainous. Often, the emigrants displayed a more realistic and typically human mixture of generosity and selfishness, an alloy born of necessity.A fast-paced, heart-wrenching, clear-eyed narrative history, A Desperate Hope casts new light on one of America's most horrific encounters between the dream of a better life and the harsh realities such dreams so often must confront.

    Terrifying photographs of mile-high dust storms, along with firsthand accounts by more than two dozen eyewitnesses, bring to life this heart-wrenching catastrophe, when a combination of drought, wind, and poor farming practices turned millions of acres of the Great Plains into a wasteland, killing crops and livestock, threatening the lives of small children, burying homesteaders' hopes under huge dunes of dirt. Burns and Duncan collected more than 300 mesmerizing photographs, some never before published, scoured private letters, government reports, and newspaper articles, and conducted in-depth interviews to produce a document that may likely be the last recorded testimony of the generation who lived through this defining decade.

    Unlikely Friendships tells one story after another of animals who, with nothing else in common, bond in the most unexpected ways and thrive on the warmth, closeness, and trust that come with being true friends.Imagine a predator cuddling its prey. Or a bird befriending a mammal. Or a fish poking its nose out of the water to nuzzle a dog. Or a massive gorilla - the one named Koko, famous for her ability to communicate in sign language - embracing a tiny kitten.Science writer Jennifer S. Holland narrates each story, and also offers insights into these relationships. Sometimes there are plausible scientific explanations: an orphan seeking comfort from an older animal; an adult yearning for a younger creature to nurture. Consider the lioness who befriended and protected a baby oryx - unexpected, but not inexplicable. Sometimes a friendship is about need, as in the case of the blind Lab and her "seeing-eye" cat. B ut sometimes it's just a lovely mystery. How else can one explain the story of Owen the hippo and Mzee the tortoise, two notoriously surly creatures who became bosom buddies?Each story reveals the true power of friendship and, to some degree, the many forms of "love" that seem to exist in the animal kingdom. Yes, scientists might scoff at that notion, but readers may feel a little differently about the world after they finish this book.
