Iron-rich immune cells in the liver may act as sensors for magnetic fields, serving as an internal compass. Scientists have long known that migrating birds and homing pigeons navigate in part by sensing the Earth’s magnetic fields, especially at night or in overcast conditions when visual landmarks or sunshine…
