    To love and loathe the fox is a British condition."The fox is our apex predator, our most beautiful and clever killer. We have witnessed its wild touch, watched it slink by bins at night and been chilled by its high-pitched scream. And yet we long to stroke the tumbling cubs outside their tunnel homes and watch the vixen stalk the cornfield.There is something about foxes. They captivate us like no other species.Exploring a long and sometimes complicated relationship, The Wild Life of the Fox captures our love – and sometimes loathing – of this magnificent creature in vivid detail and lyrical prose.

    That collaboration would mark the dawn of modern science . . . and end in murder.Johannes Kepler changed forever our understanding of the universe with his three laws of planetary motion. He demolished the ancient model of planets moving in circular orbits and laid the foundation for the universal law of gravitation, setting physics on the course of revelation it follows to this day. Kepler was one of the greatest astronomers of all time. Yet if it hadn't been for the now lesser-known Tycho Brahe, the man for whom Kepler apprenticed, Kepler would be a mere footnote in today's science books. Brahe was the Imperial Mathematician at the court of the Holy Roman Emperor in Prague and the most famous astronomer of his era. He was one of the first great systematic empirical scientists and one of the earliest founders of the modern scientific method. His forty years of planetary observations—an unparalleled treasure of empirical data—contained the key to Kepler's historic breakthrough. But those observations would become available to Kepler only after Brahe's death. This groundbreaking history portrays the turbulent collaboration between these two astronomers at the turn of the seventeenth century and their shattering discoveries that would mark the transition from medieval to modern science. But that is only half the story. Based on recent forensic evidence (analyzed here for the first time) and original research into medieval and Renaissance alchemy—all buttressed by in-depth interviews with leading historians, scientists, and medical specialists—the authors have put together shocking and compelling evidence that Tycho Brahe did not die of natural causes, as has been believed for four hundred years. He was systematically poisoned—most likely by his assistant, Johannes Kepler. An epic tale of murder and scientific discovery, Heavenly Intrigue reveals the dark side of one of history’s most brilliant minds and tells the story of court politics, personal intrigue, and superstition that surrounded the protean invention of two great astronomers and their quest to find truth and beauty in the heavens above.

    Mt. Lockley, who observed rabbits in Wales over a 5 year period, shows that they have a complex community life little understood by the world in general. These vegetarian creatures posses both dignity and 'animality'; psychological factors play as large a part in shaping their lives as they do in ours. One finds, too, that their reputation for promiscuity and wanton reproduction is really undeserved. Lockley built an artificial warren with glass sides and several tracts of natural habitat-an open plain, a woodlot, a lushly vegetated savannah were enclosed and arranged for maximum ease of observation with minimum interference. This controlled rabbit colony was observed every day and night in every season and in all kinds of weather. In Lockley's account, rabbits emerge with characteristics and personalities of their own. The nicknames he gives them (Weary Willie, Timid Timothy, Bold Benjamin, for example) in no way lessen the objective and scientific accuracy of his findings. In fact, this touch of individuality reinforces the observation that rabbits are creatures with interests, wills, and preferences of their own. Female conservatism, scent setting or 'chinning' by dominant males, the ability of the female to absorb her fertilized embryo, the stress of subordinate status...and more, are revealed here.

      Everything—from biological life to inanimate systems—generates shape and structure and evolves in a sequence of ever-improving designs in order to facilitate flow. River basins, cardiovascular systems, and bolts of lightning are very efficient flow systems to move a current—of water, blood, or electricity. Likewise, the more complex architecture of animals evolve to cover greater distance per unit of useful energy, or increase their flow across the land. Such designs also appear in human organizations, like the hierarchical "flowcharts" or reporting structures in corporations and political bodies. All are governed by the same principle, known as the Constructal Law, and configure and reconfigure themselves over time to flow more efficiently. Written in an easy style that achieves clarity without sacrificing complexity, Design in Nature is a paradigm-shifting book that will fundamentally transform our understanding of the world around us.

    The book features case discussions, USMLE-style questions, and a USMLE-style practice exam.

    Natalie Angier probes the origins of language, Paul Raffaele describes a remote Amazonian tribe untouched by the modern world, and Frans B. M. de Waal explains what a new breed of economists is learning from monkeys. Drake Bennett profiles the creator of Ecstasy and more than two hundred other psychedelic compounds -- a man hailed by some as one of the twentieth century's most important scientists.Some of the selections reflect the news of the past year. Daniel C. Dennett questions the debate over intelligent design -- is evolution just a theory? --while Chris Mooney reports on how this debate almost tore one small town apart. John Hockenberry examines how blogs are transforming the twenty-first-century battlefield, Larry Cahill probes the new science uncovering male and female brain differences, Daniel Roth explains why the programmer who made it easy to pirate movies over the Internet is now being courted by Hollywood, and Charles C.

    Now there is a clear trail to the answer, and it leads through the dense jungle of quantum physics, Zen, and subjective experience, and arrives at an unexpected destination. In this tour-de-force of scientific investigation, Evan Harris Walker shows how the operation of bizarre yet actual properties of elementary particles support a new and exciting theory of reality, based on the principles of quantum physics-a theory that answers questions such as "What is the nature of consciousness, of will?" "What is the source of material reality?" and "What is God?"

    In The Dance of Life, developmental and stem-cell biologist Magdalena Zernicka-Goetz takes us to the front lines of efforts to understand the creation of a human life. She has spent two decades unraveling the mysteries of development, as a simple fertilized egg becomes a complex human being of forty trillion cells. Zernicka-Goetz's work is both incredibly practical and astonishingly vast: her groundbreaking experiments with mouse, human, and artificial embryo models give hope to how more women can sustain viable pregnancies. Set at the intersection of science's greatest powers and humanity's greatest concern, The Dance of Life is a revelatory account of the future of fertility -- and life itself.

    Cave paintings of the giant beasts hint at the profound role they played in early human culture-our Ice Age ancestors built igloo-shaped huts out of mammoth bones and even feasted on mammoth tongues. Eager to uncover more clues to this mystical prehistoric age, explorers since the time of Peter the Great have scoured Siberia for mammoth remains. Now a new generation of explorers has taken to the tundra. Armed with GPS, ground-penetrating radar, and Soviet-era military helicopters, they seek an elusive prize: a mammoth carcass that will help determine how the creature lived, how it died-and how it might be brought back to life.In this adventure-filled narrative, science writer Richard Stone follows two teams of explorers-one Russian/Japanese, the other a French-led consortium-as they battle bitter cold, high winds, supply shortages, and the deeply rooted superstitions of indigenous peoples who fear the consequences of awakening the "rat beneath the ice." Stone travels from St. Petersburg to the Arctic Circle, from the North Sea to high-tech Japanese laboratories, as he traces the sometimes-surreal quest of these intrepid scientists, whose work could well rewrite our planet's evolutionary history. A riveting tale of high-stakes adventure and scientific hubris, Mammoth is also an intellectual voyage through uncharted moral terrain, as we confront the promise and peril of resurrecting creatures from the deep past.
