Genetics, says sociologist Barbara Katz Rothman, isn't just a science. It's a way of thinking, an ideology. She joins us today on Focus to discuss some of the controversial topics at the forefront of the field and how she addresses them in her recent book The Book of Life: A Personal Guide to Race, Normality, and the Implications of the Human Genome Project.
At the start of the last century, the average life span was just 45 years. Today the average for women is 79 and for men 72. What brought about this change? Can we expect even greater gains in human longevity? Today on Focus, we'll talk with researchers S. Jay Olshansky and Bruce Carnes on how to live as long as possible.
Today on Focus, we'll look at the people and technology involved in the effort to decode human DNA. The quest became a race between a private venture and a government-sponsored team—but now the leaders have jointly announced that the code has been cracked. But many questions remain unanswered, and today's guest on Focus will try to tackle some of them. Kevin Davies is the founding editor of Nature Genetics and author of Cracking the Genome.
