Limelight

Interesting stuff, among the things posted on Drudge - zapping fruit flies with mind-controlling lasers. Orwell would be impressed:
Using the lasers to stimulate specific brain cells, researchers say they were able to make the flies jump, walk, flap their wings and fly.

Even headless flies took flight when researchers stimulated the correct neurons, according to the study, published in the April 7 issue of the journal Cell.

Scientists say the study could ultimately help identify the cells associated with psychiatric disorders, overeating and aggressiveness.

Biologists have long known that an electrical stimulus can trigger muscle response, but this approach used focused beams of light to stimulate neurons that would have been impossible to study using electrodes.
