Book excerpt: "Goozner shows how drug innovation is driven by dedicated scientists intent on finding cures for diseases, not by pharmaceutical firms, whose bottom line often takes precedence over the advance of medicine. Stories of a university biochemist who spent twenty years searching for single blood protein that later became the best-selling biotech drug in the world, a government employee who discovered the causes for dozens of crippling genetic disorders, and the Department of Energy-funded research that made the Human Genome Project possible - these accounts illustrate how medical breakthroughs actually take place.".
