How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well. News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us. Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

"A lucid, thought-provoking account of the case for 'nature' as a determinant of personality."—Peter D. Kramer, Author of Listening to Prozac and Should You Leave? Nowhere is the nature-nurture controversy being more arduously tested than in the labs of world-renowned molecular scientist Dean Hamer, whose cutting-edge research has indisputably linked specific genes to behavioral traits, such as anxiety, thrill-seeking, and homosexuality. The culmination of that research is this provocative book, Living with Our Genes. In it, Dr. Hamer reveals that much of our behavior—how much we eat and weigh, whether we drink or use drugs, how often we have sex—is heavily influenced by genes. His findings help explain why one brother becomes a Wall Street trader, while his sibling remains content as a librarian, or why some people like to bungee-jump, while others prefer Scrabble. Dr. Hamer also sheds light on some of the most compelling and vexing aspects of personality, such as shyness, aggression, depression, and intelligence. In the tradition of the bestselling book Listening to Prozac, Living with Our Genes is the first comprehensive investigation of the crucial link between our DNA and our behavior. "Compulsive reading, reminiscent of Jared Diamond, from a scientist who knows his stuff and communicates it well."—Kirkus Reviews "A pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. Accessible . . . provocative."—Time "Absolutely terrific! I couldn't put it down."—Professor Robert Plomin, Social, Genetic & Developmental Psychiatry Research Center, Institute of Psychiatry

Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.

Get the low-down on genetics with easy-to-understand terms and clear explanations. From interpreting dominant and recessive genes to learning about mutations, this book shows the different factors that can determine a person's DNA.

Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.

Program discusses the Human Genome Project, the science behind it, and the ethical, legal and social issues raised by the project.
