Suitable for students who have little prior scientific knowledge, this book presents basic botanical principles and includes sufficient information for some shorter introductory botany courses open to both majors and nonmajors.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    It is written to impart a sense of intellectual history of biochemistry, an understanding of the tools and approaches used to solve biochemical puzzles, and a hint of the excitement that accompanies new discoveries. This edition has been thoroughly updated to reflect the most recent advances in biochemistry, particularly in the areas of genomics and structural biology. A new chapter focuses on cytoskeletal and motor proteins, currently one of the most active areas of research in biochemistry.

    With personal anecdotes, a well-written narrative, and clear examples, Human Natures is a major work of synthesis and scholarship as well as a valuable primer on genetics and evolution that makes complex scientific concepts accessible to lay readers.

    In this little book Welsh writer and artist David Wade paints a picture of one of the most elusive and pervasive concepts known to man.

    The attacks have come not only from traditional conservatives but increasingly from the postmodern left. In this essay, Stephen Hicks presents and dissects the philosophical arguments made by the postmoderns for speech restrictions and responds with a vigorous and updated liberal case for free speech.

    It combines the latest findings from the field of neuroscience with expert text and state-of-the-art illustrations and imaging techniques to provide an incomparable insight into every facet of the brain. Layer by layer, it reveals the fascinating details of this remarkable structure, covering all the key anatomy and delving into the inner workings of the mind, unlocking its many mysteries, and helping you to understand what's going on in those millions of little gray and white cells.Tricky concepts are illustrated and explained with clarity and precision, as The Human Brain Book looks at how the brain sends messages to the rest of the body, how we think and feel, how we perform unconscious actions (for example breathing), explores the nature of genius, asks why we behave the way we do, explains how we see and hear things, and how and why we dream. Physical and psychological disorders affecting the brain and nervous system are clearly illustrated and summarized in easy-to-understand terms.The unique DVD brings the subject to life with interactive elements. These include a clickable model of the brain's structure that allows the user to zoom in and discover deeper layers of detail, while complex processes, such as the journey of a nerve impulse, are broken down and simplified through intuitive animations.

    Featuring more than 600 color illustrations, this is a treasure trove of fun and fascination for the entire family.

    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.

    Created primarily for medical and premedical students, 'Neuroscience' emphasizes the structure of the nervous system, the correlation of structure and function, and the structure/function relationships particularly pertinent to the practice of medicine.

    Suitable for one- or two-semester courses, this text features illustrations and photos, traditional organization, and comprehensive coverage.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    The text is divided into three parts: the problems posed for anthropology by universals; six important studies that have forced anthropologists to rethink; and the distinctions between linguistic, cultural and social universals.

    These are exactly the conditions that millions of baby boomers are diagnosed (or already contend) with daily. Now Never Too Late to Go Vegan offers insight and practical guidance for everyone over 50 who is seeking the benefits of a plant-rich vegan diet.Authors Adams, Breitman and Messina who bring close to 75 years of vegan living to this book cover the health advantages of minimally processed vegetables, legumes, fruit, and whole grains for those 50 and older, including greater energy and vitality and more time to enjoy life. And recognizing that going vegan includes adapting one s diet but also one s life more broadly, they also explore the effects of going vegan on relationships, caregiving responsibilities, matters of the spirit, and more. Never Too Late to Go Vegan also includes 75 delicious, easy vegan recipes that meet the nutritional needs of older eaters.

    Now a world-famous theoretical physicist with hundreds of scientific articles and several books of popular science to his credit, he felt it was time to connect with nature in less theoretical ways. After seeing a fly-fishing class on the Dartmouth College green, he decided to learn to fly-fish, a hobby, he says, that teaches humility. In The Simple Beauty of the Unexpected, Gleiser travels the world to scientific conferences, fishing wherever he goes. At each stop, he ponders how in the myriad ways physics informs the act of fishing; how, in its turn, fishing serves as a lens into nature’s inner workings; and how science engages with questions of meaning and spirituality, inspiring a sense of mystery and awe of the not yet known. Personal and engaging, The Simple Beauty of the Unexpected is a scientist’s tribute to nature, an affirmation of humanity’s deep connection with and debt to Earth, and an exploration of the meaning of existence, from atom to trout to cosmos.
