Birds Have a Mysterious 'Quantum Sense'. For The First Time, Scientists Saw It in Action
Seeing our world through the eyes of a migratory bird would be a rather spooky experience. Something about their visual system allows them to 'see' our planet's magnetic field, a clever trick of quantum physics, and biochemistry that helps them nav
