Indeed, the expeditions of both Back (1837) and Ross (1849) were forced to retreat because of the rapacious illness that stalked their ships. The authors make the case that this illness was due to the crews’ overwhelming reliance on a new technology: tinned foods. This not only exposed the seamen to lead, an insidious poison, but also left them vulnerable to scurvy.The revised "Frozen in Time" will also update the research outlined in the original edition, and will introduce independent confirmation of Dr. Beattie’s lead hypothesis, along with corroboration of his discovery of physical evidence for both scurvy and cannibalism. In addition, the book includes a new introduction written by Margaret Atwood, who has long been fascinated by the role of the Franklin Expedition in Canada’s literary conscience.Includes never before seen photographs from the exhumations on Beechey Island and rarely seen historical illustrations.

    It enabled us to migrate out of Africa and to spread as far as Alaska and Australia. Every day, we put one foot in front of the other―yet how many of us know how we do that, or appreciate the advantages it gives us?Neuroscientist Shane O’Mara invites us to marvel at the benefits walking confers on our bodies and brains. From walking’s evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting- edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our “inner GPS” system. Walking, in turn, spurs our imaginations and boosts our moods. In Praise of Walking illuminates the joys, health benefits, and mechanics of walking―and reminds us to get out of our chairs and discover a happier, healthier, more creative self.

    Developing technology promises closeness. Sometimes it delivers, but much of our modern life leaves us less connected with people and more connected to simulations of them.In Alone Together, MIT technology and society professor Sherry Turkle explores the power of our new tools and toys to dramatically alter our social lives. It’s a nuanced exploration of what we are looking for—and sacrificing—in a world of electronic companions and social networking tools, and an argument that, despite the hand-waving of today’s self-described prophets of the future, it will be the next generation who will chart the path between isolation and connectivity.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.

    At once lyrical and scientific, Why We Run shows Heinrich's signature blend of biology, anthropology, psychology, and philosophy, infused with his passion to discover how and why we can achieve superhuman abilities.

    But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.

    The barriers to what we can know about our distant relatives have been falling as a result of scientific advance, such as decoding the genomes of humans and Neanderthals, and bringing together different perspectives to answer common questions. These collaborations have brought new knowledge and suggested fresh concepts to examine. The results have shaken the old certainties.The results are profound; not just for the study of the past but for appreciating why we conduct our social lives in ways, and at scales, that are familiar to all of us. But such basic familiarity raises a dilemma. When surrounded by the myriad technical and cultural innovations that support our global, urbanized lifestyles we can lose sight of the small social worlds we actually inhabit and that can be traced deep into our ancestry. So why do we need art, religion, music, kinship, myths, and all the other facets of our over-active imaginations if the reality of our effective social worlds is set by a limit of some one hundred and fifty partners (Dunbar’s number) made of family, friends, and useful acquaintances? How could such a social community lead to a city the size of London or a country as large as China? Do we really carry our hominin past into our human present? It is these small worlds, and the link they allow to the study of the past that forms the central point in this book.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.
