How many of you know what abalone is? It's a small to large-size sea snail that's quite a delicacy and used in many dishes. The abalone shell can be quite beautiful but, as discovered and presented by Angela Belcher, it can also be quite powerful. Via TedTalksDirector:
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. At TEDxCaltech, she shows us how it's done.
