Conventional wisdom dictates that our genetic destiny is fixed at conception. But Dr. Moalem's groundbreaking book shows us that the human genome is far more fluid and fascinating than your ninth grade biology teacher ever imagined. By bringing us to the bedside of his unique and complex patients, he masterfully demonstrates what rare genetic conditions can teach us all about our own health and well-being.
When are we responsible for our own actions, and when are we in the grip of biological forces beyond our control? This intriguing question is the scientific province of behavioral biology, a field that explores interactions among the brain, mind, body, and environment that have a surprising influence on how we behave—from the people we fall in love with, to the intensity of our spiritual lives, to the degree of our aggressive impulses. In short, it is the study of how our brains make us the individuals that we are.
One of the greatest scientific feats of our era is the astonishing progress made in understanding the intricate machinery of life. We are living in the most productive phase so far in this quest, as researchers delve ever deeper into the workings of living systems, turning their discoveries into new medical treatments, improved methods of growing food, and innovative new products.
We use it routinely to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. What is this powerful mystery? It is DNA—deoxyribonucleic acid, the self-replicating material present in nearly all living organisms. Award-winning teacher, author, and cancer researcher Dr. David Sadava unlocks its mysteries in his new course, Understanding Genetics: DNA, Genes, and Their Real-World Applications. He guides us through decades of scientific discovery and the weighty implications for us, as individuals and as a society.
