“ Ritz and colleagues previously identified a molecule called cryptochrome, which is found in the nerves of avian eyes, as a candidate for controlling birds’ ability to sense magnetic fields. … When the wayward electron returns to its original molecule, any change it has picked up in its spin sparks a chemical signal that some scientists believe allows birds to see magnetic fields as a pattern of colors.

Dude, I gotta get me some of that cryptochrome. I wanna see magnetic fields as a pattern of colors!
