Julia Child and physicist Philip Morrison once cooked up (and sampled) "primordial soup," a mixture of ingredients said to be the materials from which life sprang on Earth. How accurate is this notion? David Deamer studies how some molecules self-assemble into order, and has developed new theories about how life evolved from components on Earth. We’ll talk with him, do hands-on experiments, and watch vintage footage of Julia Child tasting the soup. Guests: David Deamer, Director, UC Berkeley SETI Program, and Karen Kalumuk, Exploratorium staff scientist.

Dr. Walter Gilbert, a physicist who turned to molecular biology in 1960, won the Nobel prize in chemistry in 1980 for determining the base sequences of DNA. His recent research has concentrated on the structure of genes and the evolution of DNA sequences. In this Webcast, Dr Gilbert tells us how physicists have helped drive discoveries in molecular biology, and the relationship between private and university research efforts.
