Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    Not so anymore. All but exterminated, these predators of the not-too-distant past have been reduced to minor players of the modern era. And what of it? Wildlife journalist William Stolzenburg follows in the wake of nature's topmost carnivores, and finds chaos in their absence.From the brazen mobs of deer and marauding raccoons of backyard America to streamsides of Yellowstone National Park crushed by massive herds of elk; from urchin-scoured reefs in the North Pacific to ant-devoured islands in Venezuela, Stolzenburg leads a startling tour through bizarre, impoverished landscapes of pest and plague. For anyone who has seldom given thought to the meat-eating beasts so recently missing from the web of life, here is a world of reason to think again.

    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.

    She introduces you to an African gray parrot named Alex, a bonobo named Kanzi, and a border collie named Betsy. Each of these animals tells us something interesting about the way they perceive and manipulate their world. The article also looks at what scientists are learning about the intelligence of dolphins and crows, beyond mere communication.   In “Almost Human,” Mary Roach takes us to the savannahs of Senegal to meet a group of 34 chimpanzees, whose behavior and social structures have given scientists some important clues about the nature of their communication and intelligence.   In “The Genius of Swarms,” Peter Miller looks at the collective behavior of ants, bees, and other insects for what they can tell us about social organization and how sometimes intelligence lies outside of the individual brain. This article served as the basis for his book, The Smart Swarm: How Understanding Flocks, Schools, and Colonies Can Make Us Better at Communicating, Decision Making, and Getting Things Done.

    Though the process obeyed all the rules of chemistry and physics, the details of that original event pose as deep a mystery as any facing science. How did non-living chemicals become alive? While the question is (deceivingly) simple, the answers are unquestionably complex. Science inevitably plays a key role in any discussion of life's origins, dealing less with the question of why life appeared on Earth than with where, when, and how it emerged on the blasted, barren face of our primitive planet. Astrobiologist Robert Hazen has spent many years dealing with the fundamental questions of life's genesis. As an active research scientist, he is down deep in all the messy details that science has to offer on the subject, tracing the inexorable sequence of events that led to the complicated interactions of carbonbased molecules. As he takes us through the astounding process of emergence, we are witness to the first tentative steps toward life?from the unfathomable abundance of carbon biomolecules synthesized in the black vacuum of space to the surface of the Earth to deep within our planet's restless crust. We are privy to the breathtaking drama that rapidly unfolds as life prevails. The theory of emergence is poised to answer a multitude of questions?even as it raises the possibility that natural processes exist beyond what we now know, perhaps beyond what we even comprehend. Genesis tells the tale of transforming scientific advances in our quest for life's origins. Written with grace, beauty, and authority, it goes directly to the heart of who we are and why we are here.

    Like humans, orcas are highly social and depend on their families, but Luna found himself desperately alone. So he tried to make contact with people. He begged for attention at boats and docks. He looked soulfully into people's eyes. He wanted to have his tongue rubbed. When someone whistled at him, he squeaked and whistled back. People fell in love with him, but the government decided that being friendly with Luna was bad for him, and tried to keep him away from humans. Policemen arrested people for rubbing Luna's nose. Fines were levied. Undaunted, Luna refused to give up his search for connection and people went out to meet him, like smugglers carrying friendship through the dark. But does friendship work between species? People who loved Luna couldn't agree on how to help him. Conflict came to Nootka Sound. The government built a huge net. The First Nations' members brought out their canoes. Nothing went as planned, and the ensuing events caught everyone by surprise and challenged the very nature of that special and mysterious bond we humans call friendship. The Lost Whale celebrates the life of a smart, friendly, determined, transcendent being from the sea who appeared among us like a promise out of the blue: that the greatest secrets in life are still to be discovered.

    There an odd and amiable band of nature lovers devote themselves to observing and protecting the park's rich wildlife. When a pair of red-tailed hawks builds a nest atop a Fifth Avenue apartment house across the street from the model-boat pond, Marie Winn and her fellow "Regulars" are soon transformed into obsessed hawkwatchers. The hilarious and occasionally heartbreaking saga of Pale Male and his mate as they struggle to raise a family in their unprecedented nest site, and the affectionate portrait of the humans who fall under their spell will delight and inspire readers for years to come.

    While focusing on dinosaurs it also uses them to convey other aspects of the natural sciences, including fundamental concepts in evolutionary biology, physiology, life history, and systematics. Considerable attention is devoted the nature of science itself: what it is, what it is not, and how science can be used to investigate particular kinds of questions. Dinosaurs is unique because it fills a gap between the glossy, fact-driven dinosaur books and the higher-level academic books, addressing the paleontology of dinosaurs exactly as professionals in the field do.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

    To the philosophical the  earth is eternal, while the human race -- presumptive  keeper of the world's history -- is a mere speck  in the rich stream of life. It is known that  nothing upon Earth is forever; geography, climate, and  plant and animal life are all subject to radical  change. On five occasions in the past, catastrophic  natural events have caused mass extinctions on  Earth. But today humans stand alone, in dubious  distinction, among Earth's species: Homo  Sapiens possesses the ability to destroy  entire species at will, to trigger the sixth  extinction in the history of life. In The Sixth  Extinction, Richard Leakey and Roger Lewin  consider how the grand sprawl of human life is  inexorably wreaking havoc around the world. The  authors of Origins and  Origins Reconsidered, unimpeachable  authorities on the human fossil record, turn their  attention to the most uncharted anthropological territory  of all: the future, and man's role in defining it.  According to Leakey and Lewin, man and his  surrounding species are end products of history and  chance. Now, however, humans have the unique  opportunity to recognize their influence on the global  ecosystem, and consciously steer the outcome in order  to avoid triggering an unimaginable upheaval.From the Hardcover edition.
