'''Birds, turtles, butterflies and other animals migrate''' with the help of the compasses built into their bodies. Little is known about the mechanistic nature of these compasses, and to fill the gap in knowledge, theoretical biophysicists Drs. Schulten and Solov'yov describe a nanomechanism within the birds' retina tissue, inside the rod cells, inside cryptochrome proteins known to process blue light for entraining circadian cycles, but now perhaps also deserving to be known as the seat of these organism's ability to sense magnetic fields<ref>doi:10.1529/biophysj.106.097139</ref>.
