What makes us react or feel the way we do? If you have ever asked yourself this question, then let John Medina take you on a tour of the fascinations and frustrations involved in the quest to understand the biological basis of human behavior. By describing the gap that exists between a human behavior and a human gene, this fascinating book seeks both to clarify and debunk ideas about the genetic roots of behavior, from the genes of divorce to the tendency to eat chocolate. Using Dante's The Divine Comedy as an organizing framework, The Genetic Inferno explains each of the Seven Deadly Sins, but in terms of twentieth-century genes and brains. Written by a practising research scientist, this book is not for biologists, but for literature majors, business people, parents, and anyone interested in how our genes work to make us behave the way we do.

A few gray hairs and a couple of wrinkles are often the first visible signs of aging on our bodies. For most of us, however, aging remains largely a mystery. We can only wonder why we have to age and what casualty of age hovers nearby. Written in everyday language, The Clock of Ages takes us on a tour of the aging human body--all from a research scientist's point of view. From the deliberate creation of organisms that live three times their natural span to the isolation of genes that may allow humans to do the same, The Clock of Ages also examines the latest discoveries in geriatric genetics. Sprinkled throughout the pages are descriptions of the aging of many historical figures, such as Florence Nightingale, Jane Austen, Billy the Kid, Napoleon, and Casanova. These stories underscore the common bond of senescence that unites us all. The Clock of Ages tells us why.
