    Thinking they had stumbled upon a murder victim, they reported their discovery to the police, who were baffled until they consulted the famous archaeologist P.V. Glob. Glob identified the body as that of a two-thousand-year-old man, ritually murdered and thrown in the bog as a sacrifice to the goddess of fertility. Written in the guise of a scientific detective story, this classic of archaeological history--a best-seller when it was published in England but out of print for many years--is a thoroughly engrossing and still reliable account of the religion, culture, and daily life of the European Iron Age. Includes 76 black-and-white photographs.

    Straight leg bones. Awkwardly contorted arm bones. On a hot summer day in 2005, Dr. Douglas Owsley of the Smithsonian Institution peered into an excavated grave, carefully examining the fragile skeleton that had been buried there for four hundred years. He was about fifteen years old when he died. And he was European, Owsley concluded. But how did he know? Just as forensic scientists use their knowledge of human remains to help solve crimes, they use similar skills to solve the mysteries of the long-ago past. Join author Sally M. Walker as she works alongside the scientists investigating colonial-era graves near Jamestown, Virginia, as well as other sites in Maryland. As you follow their investigations, she'll introduce you to what scientists believe are the lives of a teenage boy, a ship's captain, an indentured servant, a colonial official and his family, and an enslaved African girl. All are reaching beyond the grave to tell us their stories, which are written in bone.

    

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    Aspirin, the world's most widely used drug, is based on compounds originally extracted from the bark of a willow tree, and more than a quarter of medicines found on pharmacy shelves contain plant compounds. Now Western medicine, faced with health crises such as AIDS, Alzheimer's disease, and cancer, has begun to look to the healing plants used by indigenous peoples to develop powerful new medicines. Nowhere is the search more promising than in the Amazon, the world's largest tropical forest, home to a quarter of all botanical species on this planet—as well as hundreds of Indian tribes whose medicinal plants have never been studied by Western scientists. In Tales of a Shaman's Apprentice, ethnobotanist Mark J. Plotkin recounts his travels and studies with some of the most powerful Amazonian shamans, who taught him the plant lore their tribes have spent thousands of years gleaning from the rain forest.For more than a decade, Dr. Plotkin has raced against time to harvest and record new plants before the rain forests' fragile ecosystems succumb to overdevelopment—and before the Indians abandon their own culture and learning for the seductive appeal of Western material culture. Tales of a Shaman's Apprentice relates nine of the author's quests, taking the reader along on a wild odyssey as he participates in healing rituals; discovers the secret of curare, the lethal arrow poison that kills in minutes; tries the hallucinogenic snuff epena that enables the Indians to speak with their spirit world; and earns the respect and fellowship of the mysterious shamans as he proves that he shares both their endurance and their reverence for the rain forest. Mark Plotkin combines the Darwinian spirit of the great writer-explorers of the nineteenth century—curious, discursive, and rigorously scientific—with a very modern concern for the erosion of our environment and the vanishing culture of native peoples.

    These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    Many were fantastic, bizarre creatures that still capture our imagination: the super-predator Tyrannosaurus, the plate-backed Stegosaurus, and the long-necked, long-tailed Diplodocus. Dinosaurs: The Ultimate Guide to How They Lived taps into our enduring interest in dinosaurs, shedding new light on different dinosaur groups. Leading paleontology experts Darren Naish and Paul Barrett trace the evolution, anatomy, biology, ecology, behavior, and lifestyle of a variety of dinosaurs. They also remind us that dinosaurs are far from extinct: they present evidence supporting the evolution of dinosaurs to birds that exist today as approximately ten thousand different species. Throughout their narrative Naish and Barrett reveal state-of-the-art new findings shaping our understanding of dinosaurs. Readers will discover, for example, how the use of CT-scanning enables scientists to look inside dinosaur skulls, thus gaining new insight into their brains and sense organs. Dinosaurs is a must-have for all those wanting to keep up to date about these dynamic, complicated creatures.

    But in a world full of poisons, there was also an urgent practical need to name and recognize different plants, because most medicines were made from plant extracts.Anna Pavord takes us on a thrilling adventure into botanical history, traveling from Athens in the third century BC, through Constantinople, Venice, the medical school at Salerno to the universities of Pisa and Padua. The journey, traced here for the first time, involves the culture of Islam, the first expeditions to the Indies and the first settlers in the New World.In Athens, Aristotle's pupil Theophrastus was the first man ever to write a book about plants. How can we name, sort, and order them? He asked. The debate continues still, two thousand years later. Sumptuously illustrated in full colour, The Naming of Names gives a compelling insight into a world full of intrigue and intensely competitive egos.

    Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.

    Who fights off predators by spraying blood from its eyes? How does the slender, deep-sea gulper swallow prey twice its size? Who sucks out body fluids with its short, sharp mouthparts? Readers will learn everything they ever wanted to know about some of the scariest creatures on the planet.

    But only now, with modern resuscitation methods, are we beginning to see "Beyond Death's Door." Does death represent the end of this life or the beginning of another? Does anyone know what happens after death? Has anyone been there? What does it feel like? Is there evidence to support the biblical descriptions of hell? Anyone who has ever pondered these important questions will find new, fascinating food for thought in "Beyond Death's Door," a significant book by a leading heart specialist the recounts the experiences of individuals who have survived clinical death and returned to tell us about it.

    From Paddington Station a Great Western locomotive took me on a journey westwards from London further and further back into geological time, from the age of mammals to the age of trilobites...'So begins this enthralling exploration of time and place in which Richard Fortey peels away the top layer of the land to reveal the hidden landscape - the rocks which contain the story of distant events, which dictate not only the personality of the landscape, but the nature of the soil, the plants that grow in it and the regional characteristics of the buildings. We travel with him as our guide throughout the British Isles and as the rocks change so we learn to read the clues they contain: that Britain was once divided into two parts separated by an ocean, that Scottish malt whisky, Harris tweed, slate roofs and thatched cottages can be traced back to tumultuous events which took place many millions of years ago. The Hidden Landscape has become a classic in popular geology since its first publication in 1993. This new edition is fully updated and beautifully illustrated.

    Some past cultures even worshipped dolphins and condemned anyone who killed or wounded of them. Yet in recent decades, a paradox: on the one hand, we have discovered extraordinary depths of dolphin intelligence and their emotional lives, to the point of glimpsing their self-consciousness—on the other hand, in Japan, dolphins are slaughtered indiscriminately, and several nations keep them in cruel conditions.Diana Reiss is one of the world’s leading experts on dolphin intelligence who has helped lead the revolution in dolphin understanding for three decades. In addition, as an activist, she is a leading rescuer who helped inspire and served as an adviser for The Cove, and who continues to campaign against the annual Japanese slaughters. Here, she combines her science and activism to show us just how smart dolphins really are, and why we must stop mistreating them. Readers will be astonished at dolphins’ sonar capabilities; at their sophisticated, lifelong playfulness; at their emotional intelligence; and at their ability to bond with other species, including humans and even dogs! Her beloved companion dolphins, each with distinct personalities, create their own toys, type commands on a keyboard, tease and scold her playfully, and express their affection and delight. In Reiss’s most famous experiments, she used a mirror to prove that dolphins are self-aware, and even self-conscious. The Dolphin in the Mirror is both a scientific revelation and a emotional eye-opener, revealing one of the greatest intelligences on Earth.

    Lacking marketed products or substantial profit, the firm nonetheless saw its share price escalate from $35 to $89 in the first few minutes of trading, at that point the largest gain in stock market history. Coming at a time of economic recession and declining technological competitiveness in the United States, the event provoked banner headlines and ignited a period of speculative frenzy over biotechnology as a revolutionary means for creating new and better kinds of pharmaceuticals, untold profit, and a possible solution to national economic malaise. Drawing from an unparalleled collection of interviews with early biotech players, Sally Smith Hughes offers the first book-length history of this pioneering company, depicting Genentech’s improbable creation, precarious youth, and ascent to immense prosperity. Hughes provides intimate portraits of the people significant to Genentech’s science and business, including cofounders Herbert Boyer and Robert Swanson, and in doing so sheds new light on how personality affects the growth of science. By placing Genentech’s founders, followers, opponents, victims, and beneficiaries in context, Hughes also demonstrates how science interacts with commercial and legal interests and university research, and with government regulation, venture capital, and commercial profits. Integrating the scientific, the corporate, the contextual, and the personal, Genentech tells the story of biotechnology as it is not often told, as a risky and improbable entrepreneurial venture that had to overcome a number of powerful forces working against it.
