Biomedical enhancements, he writes, can make us smarter, have better memories, be stronger, quicker, have more stamina, live much longer, be more resistant to disease and to the frailties of aging, and enjoy richer emotional lives. They can even improve our character, or at least strengthen our powers of self-control. In spite of the benefits that biomedical enhancements may bring, many people instinctively reject them. Some worry that we will lose something important-our appreciation for what we have or what makes human beings distinctively valuable. To think clearly about enhancement, Buchanan argues, we have to acknowledge that nature is a mixed bag and that our species has many design flaws. We should be open to the possibility of becoming better than human, while never underestimating the risk that our attempts to improve may backfire.

    With expanded coverage of ethics, analysis processes, and approaches, authors Catherine Marshall and Gretchen B. Rossman, have updated this highly popular text to reflect the advances and challenges presented by provocative developments and new applications since the previous edition.

    What is it like to try to heal the body when the mind is under attack? In this book, Dr. Allan Ropper and Brian Burrell take the reader behind the scenes at Harvard Medical School's neurology unit to show how a seasoned diagnostician faces down bizarre, life-altering afflictions. Like Alice in Wonderland, Dr. Ropper inhabits a world where absurdities abound:• A figure skater whose body has become a ticking time-bomb • A salesman who drives around and around a traffic rotary, unable to get off • A college quarterback who can't stop calling the same play • A child molester who, after falling on the ice, is left with a brain that is very much dead inside a body that is very much alive • A mother of two young girls, diagnosed with ALS, who has to decide whether a life locked inside her own head is worth livingHow does one begin to treat such cases, to counsel people whose lives may be changed forever? How does one train the next generation of clinicians to deal with the moral and medical aspects of brain disease? Dr. Ropper and his colleague answer these questions by taking the reader into a rarified world where lives and minds hang in the balance.

    Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also be used by forensic scientists to identify individuals in crime. Slack also explores issues such as the role of genetic heritability and IQ as well as the changes that occur in the genes of populations during evolution. An ideal guide for anyone curious about what genes are and how genetics can be put to use, this Very Short Introduction demonstrates the ways in which the gene concept has been understood and used by molecular biologists, population biologists, and social scientists around the world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

    Now, in this much anticipated book, he documents the science and the politics that has led to the pandemic of chronic disease over the last 30 years.In the late 1970s when the government mandated we get the fat out of our food, the food industry responded by pouring more sugar in. The result has been a perfect storm, disastrously altering our biochemistry and driving our eating habits out of our control.To help us lose weight and recover our health, Lustig presents personal strategies to readjust the key hormones that regulate hunger, reward, and stress; and societal strategies to improve the health of the next generation. Compelling, controversial, and completely based in science, Fat Chance debunks the widely held notion to prove “a calorie is NOT a calorie”, and takes that science to its logical conclusion to improve health worldwide.
