A wonderful new video from the World Science Festival was uploaded 2 days ago. Titled "Quantum Biology and the Hidden Nature of Nature." With Seth Lloyd, Thorsten Ritz and Paul Davis. If you've got an hour and a half, I highly suggest watching this video. Some of the topics covered include how birds use quantum mechanics for navigation, and how plants use it in photosynthesis.
