In animals, cryptochrome proteins are thought to be the detectors of the Earth's magnetic field, but humans have not been shown to posess mangetosensing capabilities. Foleyet al. demonstrate that the human cryptochrome protein, CRY2, when expressed in Drosophila melanogastercan mediate magnetoreception in a light-dependent manner.
