Yale Researchers Use Laser Light To Remote Control Flies Scientists at Yale have genetically designed triggers in the brains of fruit flies that allow the flies' behavior to be controlled with laser light. In some experiments they altered how the flies jump, beat their wings and fly in an escape response. In others, they activated dopamine neurons that stimulated walking and affected the paths the flies followed. Loss of dopamine cell activity in humans underlies the movement disorder of Parkinson's disease. Why Are Some People Oblivious To The 'Sweaty'Smell Of A Locker Room? Some people are oblivious to the odor in the locker room after a game, while others wrinkle their noses at the slightest whiff of sweat. This difference is at least partly genetic.
