Fruit Fly Fight Club
7 February 2014 10:00 am
To better understand aggressive behavior and its evolutionary roots, researchers recorded male fruit flies wrestling and examined their brains, The New York Times reports. They found males have special neurons that release a substance that causes them to become violent—but its production can be controlled by genetic manipulation to make the flies calm down or become angrier. The same chemical exists in humans and is known as “substance P,” and it may pave the way for a drug that curbs aggression.
