Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives?male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon?s golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon?s Steed brings to life an aquatic treasure.Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon?s Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses? unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a ?keystone? species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

    Anderson. Working from Frank Herbert's own notes, the acclaimed authors reveal the chapter of the Dune saga most eagerly anticipated by readers: the Butlerian Jihad.Throughout the Dune novels, Frank Herbert frequently referred to the war in which humans wrested their freedom from "thinking machines." In Dune: The Butlerian Jihad, Brian Herbert and Kevin J. Anderson bring to life the story of that war, a tale previously seen only in tantalizing hints and clues. Finally, we see how Serena Butler's passionate grief ignites the struggle that will liberate humans from their machine masters; here is the amazing tale of the Zensunni Wanderers, who escape bondage to flee to the desert world where they will declare themselves the Free Men of Dune. And here is the backward, nearly forgotten planet of Arrakis, where traders have discovered the remarkable properties of the spice melange. . . . Dune: The Machine Crusade More than two decades have passed since the events chronicled in Dune: The Butlerian Jihad. The crusade against thinking robots has ground on for years, but the forces led by Serena Butler and Irbis Ginjo have made only slight gains; the human worlds grow weary of war, of the bloody, inconclusive swing from victory to defeat.The fearsome cymeks, led by Agamemnon, hatch new plots to regain their lost power from Omnius--as their numbers dwindle and time begins to run out. The fighters of Ginaz, led by Jool Noret, forge themselves into an elite warrior class, a weapon against the machine-dominated worlds. Aurelius Venport and Norma Cenva are on the verge of the most important discovery in human history-a way to "fold" space and travel instantaneously to any place in the galaxy.And on the faraway, nearly worthless planet of Arrakis, Selim Wormrider and his band of outlaws take the first steps to making themselves the feared fighters who will change the course of history: the Fremen.Here is the unrivaled imaginative power that has put Brian Herbert and Kevin Anderson on bestseller lists everywhere and earned them the high regard of readers around the globe. The fantastic saga of Dune continues in Dune: The Machine Crusade. Dune: The Battle of Corrin It has been fifty-six hard years since the events of Dune: The Machine Crusade. Following the death of Serena Butler, the bloodiest decades of the Jihad take place. Synchronized Worlds and Unallied Planets are liberated one by one, and at long last, after years of victory, the human worlds begin to hope that the end of the centuries-long conflict with the thinking machines is finally in sight.Unfortunately, Omnius has one last, deadly card to play. In a last-ditch effort to destroy humankind, virulent plagues are let loose throughout the galaxy, decimating the populations of whole planets . . . and once again, the tide of the titanic struggle shifts against the warriors of the human race. At last, the war that has lasted many lifetimes will be decided in the apocalyptic Battle of Corrin.In the greatest battle in science fiction history, human and machine face off one last time. . . . And on the desert planet of Arrakis, the legendary Fremen of Dune become the feared fighting force to be discovered by Paul Muad'Dib in Frank Herbert's classic, Dune.

    Dave Williams, one of Canada’s most accomplished astronauts.I had dreamt about becoming an astronaut from the time I watched Alan Shepard launch on the first American sub-orbital flight on May 5, 1961. Eleven days before my seventh birthday, I committed to a new goal: one day, I would fly in outer space. Dr. Dave has led the sort of life that most people only dream of. He has set records for spacewalking. He has lived undersea for weeks at a time. He has saved lives as an emergency doctor, launched into the stratosphere twice, and performed surgery in zero gravity. But if you ask him how he became so accomplished, he’ll say: “I’m just a curious kid from Saskatchewan.” Curious indeed. Dr. Dave never lost his desire to explore nor his fascination with the world. Whether he was exploring the woods behind his childhood home or floating in space at the end of the Canadarm, Dave tried to see every moment of his life as filled with beauty and meaning. He learned to scuba dive at only twelve years old, became a doctor despite academic struggles as an undergraduate, and overcame stiff odds and fierce competition to join the ranks of the astronauts he had idolized as a child. There were setbacks and challenges along the way—the loss of friends in the Columbia disaster, a cancer diagnosis that nearly prevented him from returning to space—but through it all, Dave never lost sight of his goal. And when he finally had the chance to fly among the stars, he came to realize that although the destination can be spectacular, it’s the journey that truly matters. In Defying Limits, Dave shares the events that have defined his life, showing us that whether we’re gravity-defying astronauts or earth-bound terrestrials, we can all live an infinite, fulfilled life by relishing the value and importance of each moment. The greatest fear that we all face is not the fear of dying, but the fear of never having lived. Each of us is greater than we believe. And, together, we can exceed our limits to soar farther and higher than we ever imagined.

    In movies, in novels, in comic strips, and on television, we’ve all seen dinosaurs—or at least somebody’s educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur, without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on Jurassic Park, and a pioneer in bringing paleontology into the twenty-first century, teams up with the editor of The New York Times’s Science Times section to reveal exactly what’s in store. In the 1980s, Horner began using CAT scans to look inside fossilized dinosaur eggs, and he and his colleagues have been delving deeper ever since. At North Carolina State University, Mary Schweitzer has extracted fossil molecules—proteins that survived 68 million years—from a Tyrannosaurus rex fossil excavated by Horner. These proteins show that T. rex and the modern chicken are kissing cousins. At McGill University, Hans Larsson is manipulating a chicken embryo to awaken the dinosaur within: starting by growing a tail and eventually prompting it to grow the forelimbs of a dinosaur. All of this is happening without changing a single gene. This incredible research is leading to discoveries and applications so profound they’re scary in the power they confer on humanity. How to Build a Dinosaur is a tour of the hot rocky deserts and air-conditioned laboratories at the forefront of this scientific revolution.

    And with good reason. Our biology is set up to work in partnership with the sun. From our sleep cycles to our immune systems and our mental health, access to sunlight is crucial for living a happy and fulfilling life. New research suggests that our sun exposure over a lifetime - even before we were born - may shape our risk of developing a range of different illnesses, from depression to diabetes. Bursting with cutting-edge science and eye-opening advice, Chasing the Sun explores the extraordinary significance of sunlight - from ancient solstice celebrations to modern sleep labs, and from the unexpected health benefits of sun exposure to what the Amish know about sleep that the rest of us don't. As more of us move into light-polluted cities, spending our days in dim offices and our evenings watching brightly lit screens, we are in danger of losing something vital: our connection to the star that gave us life. It's a loss that could have far-reaching consequences that we're only just beginning to grasp.

    Uranium is both productive (nuclear power) and destructive (nuclear bombs); iron is the bloody weapon of war, but also the economic tool of peace; our desire for alluring gold is the foundation of global trade, but has also led to the death of millions. John Browne, CEO of British Petroleum (BP) for twelve years, vividly describes how seven elements are shaping the world around us, for better and for worse.Combining history, science, and politics, Seven Elements takes you on a present-day adventure of human passion and innovation. This journey is far from over: we continue to find surprising new uses for these seven elements. In this narrative of discovery, readers will come to understand how titanium pervades modern consumer society, how natural gas is transforming the global energy sector, and how an innovative new form of carbon could be starting a technology revolution.

    New 'Consolidation' sections and questions designed to provide a link between GCSE and A-level feature in the text.At the end of each section there are many questions - ideal for consolidation and revision - mainly from past A-level examination papers. Over 15 of these past-paper questions have been added in the Fourth Edition. Answers are included.

    To shape debates over health care, energy policy, space travel, and other vital issues, ordinary citizens must engage directly with research rather than relying on pundits’ and politicians’ interpretations. Otherwise, fringe opinions that have been discredited in the scientific community can take hold in the public imagination. At the same time, scientists must understand their roles as communicators and ambassadors as well as researchers.Rees not only diagnoses this central problem but also explains how scientists and the general public can deploy a global, long-term perspective to address the new challenges we face. In the process, he reveals critical shortcomings in our current system—for example, the tendency to be overly anxious about minor hazards while underrating the risk of potential catastrophes. Offering a strikingly clear portrait of the future of science, Rees tackles such diverse topics as the human brain, the possibility that humans will colonize other planets, and the existence of extraterrestrial life in order to distinguish between what scientists can hope to discover and what will always lie beyond our grasp.A fresh perspective on science’s significance and potential, From Here to Infinity will inspire and enlighten.

    Did you know that the peacock mantis shrimp has the most powerful punch on Earth? That vampire spiders are attracted to your smelly socks? That the lesser water boatman is the loudest animal in the world and its instrument is its own penis? Or that concave-eared frogs have a secret language that only males can hear? From the mother-eating black-lace weaver spiders to Texas horned lizards that can shoot jets of poisonous blood from their eyes, this book from fearless science blogger Becky Crew will introduce you to a menagerie of the world’s weirdest animals.

    But Beyond Earth does not offer another wide-eyed technology fantasy: instead it is grounded not only in the human capacity for invention and the appeal of adventure but also in the bureaucratic, political, and scientific realities that present obstacles to space travel - realities that have hampered NASA's efforts ever since the Challenger fiasco. In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.

    A place 200 million years in the making.Long ago, our planet had only one gigantic land mass. Then something monumental happened. That supercontinent ruptured and seven different worlds were born. Each of those worlds - or continents - evolved, and continues to evolve, its own way of life. From the jungle of the Congo or the majestic Himalayas to the densely populated wilds of Europe or the comparatively isolated Australasia, Seven Worlds, One Planet explores the natural wonders that give each of our continents its distinct character. Following the animals that have made these iconic environments their home, it discovers spectacular wildlife stories that reveal what makes each of these seven worlds unique. With a foreword by Sir David Attenborough and over 250 breathtaking images, including stills from the BBC Natural History Unit’s spectacular footage, Seven Worlds, One Planet is a stunning exploration of the planet, and the worlds within it, that we call home.

    

    A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. First Steps examines how walking upright helped us rise above all over species on this planet.First Steps includes an eight-page color photo insert.

    Presidents John F. Kennedy and Lyndon Johnson utilized the space program as an agent for social change, using federal equal employment opportunity laws to open workplaces at NASA and NASA contractors to African Americans while creating thousands of research and technology jobs in the Deep South to ameliorate poverty. 'We Could Not Fail' tells the inspiring, largely unknown story of how shooting for the stars helped to overcome segregation on earth.Richard Paul and Steven Moss profile 10 pioneer African American space workers whose stories illustrate the role NASA and the space program played in promoting civil rights. They recount how these technicians, mathematicians, engineers, and an astronaut candidate surmounted barriers to move, in some cases literally, from the cotton fields to the launching pad. The authors vividly describe what it was like to be the sole African American in a NASA work group and how these brave and determined men also helped to transform Southern society by integrating colleges, patenting new inventions, holding elective offices, as well as reviving and governing defunct towns. Adding new names to the roster of civil rights heroes and a new chapter to the story of space exploration, 'We Could Not Fail' demonstrates how African Americans broke the color barrier by competing successfully at the highest level of American intellectual and technological achievement.©2015 Richard Paul and Steven Moss (P)2019 Audible, Inc

    Cabinet of Curiosities is a lavishly illustrated introduction to the wonders of natural history and the joys of being an amateur scientist and collector. Nature writer Gordon Grice, who started his first cabinet of curiosities at age six when he found a skunk’s skull, explains how scientists classify all living things through the Linnaeus system; how to tell real gold from fool’s gold; how to preserve butterflies, crab shells, feathers, a robin’s egg, spider specimens, and honeycombs; how to identify seashells; the difference between antlers and horns; how to read animal tracks. And then, what to do with your specimens, including how to build a cabinet of curiosities out of common household objects, like a desk organizer or a box for fishing tackle.
