(EMBL/P. Riedinger) Protein In The Human Retina Can 'Sense' Magnetic Fields. Researchers say that a protein expressed in the human retina, human cryptochrome 2 protein (hCRY2), can sense magnetic fields when implanted into Drosophila, leading to an interesting topic in sensory biology; perhaps humans have an innate magnetic sense.
Migratory birds and sea turtles do, and that ability to sense the Earth's magnetic field is how they navigate long-distance voyages during migration. In many migratory animals, the light-sensitive chemical reactions in the flavoprotein cryptochrome (CRY) are thought to play an important role in the ability to sense the Earth's magnetic field.
