How Birds See Earth's Magnetic Field ⚡ экспресс
Original: "Quantum modeling of radical pair magnetic sensor based on electric dipole moment"
In birds' retinas, a protein called cryptochrome converts light and magnetic fields into an electrical signal, letting them see direction.

A bird's eye hides a compass—not a needle, but a protein that turns magnetic fields into electricity. This discovery will enable tiny sensors for navigation without GPS.
🎯 This same protein is present in human eyes too, but in us it only regulates biological clocks, and we don't sense magnetic fields.
