Fun Fact
Quantum bird compass: European robins can only use their built-in magnetic compass when blue light is shining in their eyes.
Glossary
cryptochrome (noun)
A class of light-sensitive flavoproteins found in plants and animals that regulate various biological processes. In 2000, physicist Thorsten Ritz proposed that European robins use this retinal protein for geomagnetic navigation.
