Using Linux and lasers, researchers can now control the minds of fruit flies

Imagine you’re a fruit fly, sniffing your way to your next feast of overripe produce. Suddenly, out of the blue you become engulfed in indigo light. Immediately you forget about the fruit, instead landing, and through no natural impulse of your own, begin singing and dancing your little insect heart out. No, your little insect self hasn’t been abducted by aliens. Instead, you’ve just become the newest test subject of the very real Dr. Andrew Straw.
