Physiology: Mutant flies lack magnetic sense
François Rouyer1
Abstract
It seems that fruitflies can detect magnetic fields, but only if they are illuminated with blue light. Mutant flies reveal that a light-responsive receptor underpins this peculiar behaviour.
Animals detect various wavelengths of light, from ultraviolet to red, using photoreceptor proteins. One reason for doing this is to synchronize their circadian clocks with the day–night cycle.
