Bioluminescence

Did you happen to read the article that came out last week about the discovery that people glow in visible light in really low levels? I found it so interesting. I've had a fascination since childhood with animals that can glow. They say we can't see humans glow with our own eyes but I beg to differ. When I'm with certain people I swear I can see them glow.

Here is a great video of glowing fish. c.
