In this groundbreaking analysis, over thirty of the most popular treatments—acupuncture, homeopathy, aromatherapy, reflexology, chiropractic, and herbal medicines—are examined for their benefits and potential dangers. Questions answered include: What works and what doesn't? What are the secrets, and what are the lies? Who can you trust, and who is ripping you off? Can science decide what is best, or do the old wives' tales really tap into ancient, superior wisdom?In their scrutiny of alternative and complementary cures, authors Simon Singh and Edzard Ernst also strive to reassert the primacy of the scientific method as a means for determining public health practice and policy.

    Here, Michael Tomasello proposes a complementary theory of human uniqueness, focused on development. Building on the seminal ideas of Vygotsky, his data-driven model explains how those things that make us most human are constructed during the first years of a child's life.Tomasello assembles nearly three decades of experimental work with chimpanzees, bonobos, and human children to propose a new framework for psychological growth between birth and seven years of age. He identifies eight pathways that starkly differentiate humans from their closest primate relatives: social cognition, communication, cultural learning, cooperative thinking, collaboration, prosociality, social norms, and moral identity. In each of these, great apes possess rudimentary abilities. But then, Tomasello argues, the maturation of humans' evolved capacities for shared intentionality transform these abilities--through the new forms of sociocultural interaction they enable--into uniquely human cognition and sociality. The first step occurs around nine months, with the emergence of joint intentionality, exercised mostly with caregiving adults. The second step occurs around three years, with the emergence of collective intentionality involving both authoritative adults, who convey cultural knowledge, and coequal peers, who elicit collaboration and communication. Finally, by age six or seven, children become responsible for self-regulating their beliefs and actions so that they comport with cultural norms.Becoming Human places human sociocultural activity within the framework of modern evolutionary theory, and shows how biology creates the conditions under which culture does its work.

    By 15,000 BC, humans had migratedfrom northeastern Asia across the frozen Beringland bridge to the Americas. When the world warmed up and the last Ice Age came to an end,the Bering Strait refilled with water, dividing America from Eurasia. This division—with two great populations on Earth, each unaware of theater—continued until Christopher Columbus voyaged to the New World in the fifteenth century.The Great Divide compares the development of human kind in the Old World and the New between 15,000 BC and AD 1500. Watson identifies three major differences between the two worlds—climate, domesticable mammals, and hallucinogenic plants—that combined to produce very different trajectories of civilization in the two hemispheres. Combining the most up-to-date knowledge in archaeology, anthropology, geology, meteorology, cosmology, and mythology, this unprecedented, masterful study offers uniquely revealing insight into what it means to be human.

    In Tales from the Underground, Cornell ecologist David Wolfe takes us on a tour through current scientific knowledge of the subterranean world. We follow the progress of discovery from Charles Darwin's experiments with earthworms, to Lewis and Clark's first encounter with prairie dogs, to the use of new genetic tools that are revealing an astonishingly rich ecosystem beneath our feet. Wolfe plunges us deep into the earth's rocky crust, where life may have begun-a world devoid of oxygen and light but safe from asteroid bombardment. Primitive microbes found there are turning our notion of the evolutionary tree of life on its head: amazingly, they represent perhaps a full third of earth's genetic diversity. As Wolfe explains, creatures of the soil can work for us, by providing important pharmaceuticals and recycling the essential elements of life, or against us, by spreading disease and contributing to global climate change. The future of our species may well depend on how we manage our living soil resources. Tales from the Underground will forever alter our appreciation of the natural world around-and beneath-us.

    He deflates the myths surrounding scientists -- invincibility, superiority, and genius; instead, he argues that it is common sense and an inquiring mind that are essential to the makeup of a scientist. He delivers many wry observations on how to choose a research topic, how to get along wih collaborators and older scientists and administrators, how (and how not) to present a scientific paper, and how to cope with culturally "superior" specialists in the arts and humanities.

    The Los Angeles Times has listed it among the one hundred most influential books published in the last quarter century, Outside Magazine has included it in a survey of books that changed our world, and it has been called the Book of Genesis for environmentalists. Now a fourth edition of this highly regarded work is available, with a new preface and epilogue in which Nash explores the future of wilderness and reflects on its ethical and biocentric relevance.
