Kids will discover how their voice box works, how many bones they have, how thousands of "tasters" on their tongues help them distinguish flavors, how the DNA in their cells is different from everyone else's, and so much more. Filled with astonishing details, this head-to-toe survey of the body is fascinating to read and fun to color!

    It remains an elementary and non-mathematical introduction to molecular spectroscopy that emphasizes the overall unity of the subject and offers a pictorial perception rather than a mathematical description of the principles of spectroscopy.

    

    The culprit--so necessary and yet the source of such upheaval--is the X chromosome, and this is its story. An enlightening and entertaining tour of the cultural and natural history of this intriguing member of the genome, "The X in Sex" traces the journey toward our current understanding of the nature of X. From its chance discovery in the nineteenth century to the promise and implications of ongoing research, David Bainbridge shows how the X evolved and where it and its counterpart Y are going, how it helps assign developing human babies their sex--and maybe even their sexuality--and how it affects our lives in infinitely complex and subtle ways. X offers cures for disease, challenges our cultural, ethical, and scientific assumptions about maleness and femaleness, and has even reshaped our views of human evolution and human nature.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    On trial for murder, she prayed for a miracle. And she got one, sort of: a deadlocked jury. A mistrial meant going through the ordeal all over again, but at least she'd have more time to prove her innocence. And now handsome police officer Dan Ryan was on her side, determined to find evidence that would clear her name. But Laurel didn't even know what to look for, or who would want her husband dead. Until Dan took her back to the scene of the crime. . .where a killer was waiting.

    Its unique 'Frontiers' chapters cover materials science, nanotechnology, catalysis, and biological inorganic chemistry, and have been fully updated to reflect advances in these key areas of contemporary research and industrial application.

    It was originally published in 1986.

    Revised to reflect the latest research in the field, this book emphasizes the relationships and concepts that link cell and tissue structures with their functions. A bonus image library CD-ROM featuring all the photos and illustrations from the text with "zoom in" and "zoom out" capability is also included.

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation. Or, for that matter, whether flamingos are really real.

    Her experiences are a must-read for anyone who loves the untamed nature and wondrous beauty of Maine's north woods and the unique spirit of those who lived there. In the 1930s, in spite of being warned that remote Churchill Depot was "no place for a woman," the remarkable Helen Hamlin set off at age twenty to teach school at the isolated lumber camp at the headwaters of the Allagash River. She eventually married a game warden and moved deeper into the wilderness. In her book, Hamlin captures that time in her life, complete with the trappers, foresters, lumbermen, woods folk, wild animals, and natural splendor that she found at Umsaskis Lake and then at Nine Mile Bridge on the St. John River.

    Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.
