In pursuit of these things, it is undeterred by emotion, fear, or morality. Dopamine is the source of our every urge, that little bit of biology that makes an ambitious business professional sacrifice everything in pursuit of success, or that drives a satisfied spouse to risk it all for the thrill of someone new. Simply put, it is why we seek and succeed; it is why we discover and prosper. Yet, at the same time, it’s why we gamble and squander. From dopamine’s point of view, it’s not the having that matters. It’s getting something—anything—that’s new. From this understanding—the difference between possessing something versus anticipating it—we can understand in a revolutionary new way why we behave as we do in love, business, addiction, politics, religion – and we can even predict those behaviors in ourselves and others. In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and why the brains of liberals and conservatives really are different.

    He is one of the foremost figures of contemporary neuroscience, and his decades-long quest to understand the inner workings of the brain’s memory machine has begun to pay off. Award-winning journalist Terry McDermott spent nearly two years observing Lynch at work and now gives us a fascinating and dramatic account of daily life in his lab—the highs and lows, the drudgery and eureka moments, the agonizing failures. He provides detailed, lucid explanations of the cutting-edge science that enabled Lynch to reveal the inner workings of the molecular machine that manufactures memory. After establishing the building blocks, Lynch then set his sights on uncovering the complicated structure of memory as it is stored across many neurons. Adding practical significance to his groundbreaking work, Lynch discovered a class of drugs that could fix the memory machine when it breaks, drugs that would enhance brain function during the memory process and that hold out the possibility of cures for a wide range of neurological conditions, including Alzheimer’s disease, Parkinson’s disease, and attention deficit hyperactivity disorder. Here is an essential story of science, scientists, and scientific achievement—galvanizing in the telling and thrilling in its far-reaching implications.

    Crisscrossing the continent, Flannery shows us how the destiny of this extraordinary creature is inseparable from the environment that created it. Along the way he uses encounters with ancient aboriginal cultures and eccentric fossil hunters, farmers and scientists, kangaroo advocates and kangaroo hunters, to explore how Australia’s deserts and rainforests have shaped human responses to the continent -- and how kangaroos have evolved to handle the resulting challenges. Ultimately, Chasing Kangaroos is a smart yet utterly readable synthesis of memoir, travel, natural history, and evolutionary science -- and further proof of Flannery’s “offhand interdisciplinary brilliance” ( Entertainment Weekly ).

    The mind-body problem cannot be confined to the relation between animal minds and animal bodies. If materialism cannot accommodate consciousness and other mind-related aspects of reality, then we must abandon a purely materialist understanding of nature in general, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. No such explanation is available, and the physical sciences, including molecular biology, cannot be expected to provide one. The book explores these problems through a general treatment of the obstacles to reductionism, with more specific application to the phenomena of consciousness, cognition, and value. The conclusion is that physics cannot be the theory of everything.

    But philosopher and cognitive scientist Andy Clark sees it differently. Cyborgs, he writes, are not something to be feared--we already are cyborgs. In Natural-Born Cyborgs, Clark argues that what makes humans so different from other species is our capacity to fully incorporate tools and supporting cultural practices into our existence. Technology as simple as writing on a sketchpad, as familiar as Google or a cellular phone, and as potentially revolutionary as mind-extending neural implants--all exploit our brains' astonishingly plastic nature. Our minds are primed to seek out and incorporate non-biological resources, so that we actually think and feel through our best technologies. Drawing on his expertise in cognitive science, Clark demonstrates that our sense of self and of physical presence can be expanded to a remarkable extent, placing the long-existing telephone and the emerging technology of telepresence on the same continuum. He explores ways in which we have adapted our lives to make use of technology (the measurement of time, for example, has wrought enormous changes in human existence), as well as ways in which increasingly fluid technologies can adapt to individual users during normal use. Bio-technological unions, Clark argues, are evolving with a speed never seen before in history. As we enter an age of wearable computers, sensory augmentation, wireless devices, intelligent environments, thought-controlled prosthetics, and rapid-fire information search and retrieval, the line between the user and her tools grows thinner day by day. This double whammy of plastic brains and increasingly responsive and well-fitted tools creates an unprecedented opportunity for ever-closer kinds of human-machine merger, he writes, arguing that such a merger is entirely natural. A stunning new look at the human brain and the human self, Natural Born Cyborgs reveals how our technology is indeed inseparable from who we are and how we think.

    Contrasting the views of medical science with those of ordinary women from diverse social and economic backgrounds, anthropologist Emily Martin presents unique fieldwork on American culture and uncovers the metaphors of economy and alienation that pervade women's imaging of themselves and their bodies. A new preface examines some of the latest medical ideas about women's reproductive cycles.
