Nobel Laureate Flexes Artistic Muscle

Nobel Laureate Walter Gilbert — lauded for his contributions to DNA sequencing — "now works with a computer and camera instead of test tubes and chemicals," according to Sara Appel-Lennon at La Jolla Light. Gilbert, now an accomplished digital photographer, has put on 29 solo exhibitions over the last eight years. He told the weekly that "science and art unleash creative impulses — a desire to find new things about the world. Both require risk and experimentation. Both scientists and artists enjoy seeking what's new and different." Gilbert will exhibit his artwork on Sept. 4 as part of Art San Diego.
