The scent of a single chemical can turn peaceful, happy fruit flies into flying fists of fury.
For the first time, scientists have found a rage-inducing pheromone and the neuron that detects it in fruit flies. The research, detailed in the journal Nature, could help explain everything from bar fights to species-wide population control.
"Not only did we identify the pheromone that leads to aggression and its neuron," said David Anderson, a scientist at Cal Tech and co-author of the Nature study, "but we were able to manipulate the ability of the flies to increase aggression."
For the most part, fruit flies are a peaceful species. Give a group of flies a piece of food, and they graze peacefully. Give them some land, and they usually share the territory without incident.
