This is a clear, vivid text with charts and maps showing the positions of the constellations the year round.

    An x-ray microscope would do the trick, or since we're dreaming, perhaps an Asimov-style nanosubmarine (unfortunately, neither is currently feasible). Think of the wonders we could witness firsthand: antibodies atta- ing a virus, electrical signals racing down nerve fibers, proteins building new strands of DNA. Many of the questions puzzling the current cadre of sci- tists would be answered at a glance. But the nanoscale world of molecules is separated from our everyday world of experience by a daunting million-fold difference in size, so the world of molecules is completely invisible. I created the illustrations in this book to help bridge this gulf and allow us to see the molecular structure of cells, if not directly, then in an artistic rendition. I have included two types of illustrations with this goal in mind: watercolor paintings which magnify a small portion of a living cell by one million times, showing the arrangement of molecules inside, and comput- generated pictures, which show the atomic details of individual molecules. In this second edition of The Machinery of Life, these illustrations are presented in full color, and they incorporate many of the exciting scientific advances of the 15 years since the first edition.

    Why do living things and physical phenomena take the forms they do? Analyzing the mathematical and physical aspects of biological processes, this historic work, first published in 1917, has become renowned as well for the poetry of is descriptions.

    The mosquito has become resistant to DDT; malaria is on the rise; although tapeworms rarely turn up any longer in the most lovingly prepared New York City gefilte fish, a worm may inhabit your sashimi; some strains of gonorrhea actually thrive on penicillin; there is even a parasite for the higher tax brackets—the "nymph of Nantucket"; and there are new ailments—legionnaire's disease, Lassa fever, and new strains of influenza.In the long run, one might bet on the insects and the germs. Meanwhile Dr. Robert Desowitz has written a delightful and instructive book.

    Get ready to unthink what you thought you knew and journey into the deep, dark depths of the Jurassic.The discovery of the first feathered dinosaur in China in 1996 sent shockwaves through the palaeontological world. Were the feathers part of a complex mating ritual, or a stepping stone in the evolution of flight? And just how closely related is T. rex to a chicken? Award-winning journalist John Pickrell reveals how dinosaurs developed flight and became the birds in our backyards. He delves into the latest discoveries in China, the US, Europe and uncovers a thriving black market in fossils and infighting between dinosaur hunters, plus the controversial plan to use a chicken to bring dinosaurs back from the dead.

    In biology labs across the world, fruit flies are turning up answers to some of the basic questions of life. It's business as usual for the fly, which for generations has been defining biology's major landmarks. From genetics to development, behavior to aging, and evolution to the origin of species, the fruit fly has been a key player in some of the twentieth century's greatest biological discoveries.Techniques to pinpoint genes that play a role in human disease depend on genetic mapmaking principles first established with the fly. It was experiments on fruit flies that opened our eyes to the dangers of radiation to human health. In fact, everything from gene therapy to cloning to the Human Genome Project is built on the foundation of fruit fly research. Despite its many achievements, the fruit fly remains an unsung hero in the history of science. At last, here is a book that gives the fly its long overdue credit.In a highly original, witty, and irreverent style, Martin Brookes takes us through successive stages in the life cycle of the fly, each illustrating an important concept in biology. Some, such as the fundamentals of heredity, are well established; others, such as sexual warfare, learning, and memory, are still in their infancy. But whether flies are getting high on crack cocaine, enjoying the pleasures and pains of a boozy night out, being trained by punishment and reward, or struggling with insomnia, this book provides a glimpse of how one short life has informed almost every aspect of human existence. The result is a broad introduction to biology with insights into the practical realities of science.Often dismissed as irrelevant outside academic circles, the fruit fly, through this distinctive biography, will come to be recognized for what it really is: an icon of twentieth-century science and a window on our own biological world.

    In this beautiful new one-volume edition, modern readers are introduced to one of the best nature writers of the last century. More than one hundred of the original illustrations by Paul Landacre highlight the eloquent and entertaining accounts of American trees. As we read Peattie's descriptions, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly.Here you'll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.

    Author David Helvarg takes the reader on both a geographic and literary journey along the 1,100-mile Pacific coastline, from the Oregon border to the San Diego/Tijuana international border fence and out into its whale-, seal-, and shark-rich offshore seamounts, rock isles, and kelp forests.Part history, part travelogue, part love letter, The Golden Shore tells the story of California’s majestic coastline and ocean. Helvarg captures the spirit of the Californian coast, its mythic place in American culture, and its role in a state whose ongoing natural disasters and unremitting sense of renewal are intimately linked to its deep connection with an ever-changing sea.

    From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food.Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

    Like Jared Diamond's Guns, Germs and Steel, Mapping Human History is a groundbreaking synthesis of science and history. Drawing on a wide range of sources, including the latest genetic research, linguistic evidence, and archaeological findings, Olson reveals the surprising unity among modern humans and "demonstrates just how naive some of our ideas about our human ancestry have been" (Discover).Olson offers a genealogy of all humanity, explaining, for instance, why everyone can claim Julius Caesar and Confucius as forebears. Olson also provides startling new perspectives on the invention of agriculture, the peopling of the Americas, the origins of language, the history of the Jews, and more. An engaging and lucid account, Mapping Human History will forever change how we think about ourselves and our relations with others.

    As the wolves hunted and killed the island’s moose, a young graduate student named Dave Mech began research that would unlock the mystery of one of nature’s most revered (and reviled) animals—and eventually became an internationally renowned and respected wolf expert. This is the story of those early years.Wolf Island recounts three extraordinary summers and winters Mech spent on the isolated outpost of Isle Royale National Park, tracking and observing wolves and moose on foot and by airplane—and upending the common misperception of wolves as destructive killers of insatiable appetite. Mech sets the scene with one of his most thrilling encounters: witnessing an aerial view of a spectacular hunt, then venturing by snowshoe (against the pilot’s warning) to photograph the pack of hungry wolves at their kill. Wolf Island owes as much to the spirit of adventure as to the impetus of scientific curiosity. Written with science and outdoor writer Greg Breining, who recorded hours of interviews with Mech and had access to his journals and field notes from those years, the book captures the immediacy of scientific fieldwork in all its triumphs and frustrations. It takes us back to the beginning of a classic environmental study that continues today, spanning nearly sixty years—research and experiences that would transform one of the most despised creatures on Earth into an icon of wilderness and ecological health.
