A Genetically Engineered Fly That Can Smell Light

An anonymous reader writes "It sounds like a cool — if somewhat pointless — super-powered insect: a fly that can smell light! Researchers added a light-sensitive protein to a fruit fly's olfactory neurons, which caused the neurons to fire when the fly was exposed to a certain wavelength of blue light. Adding the protein specifically to neurons that respond to good smells, like bananas, makes for a light-seeking fly."
