## Resource

Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. In her talk, she shows us how it's done. (Filmed at TEDxCaltech.)Talk by Angela Belcher. Learn more about your ad choices. Visit megaphone.fm/adchoices
