most successful group of animals inhabiting every corner of the world, have offered a clue to scientists on how to cope with stress. They have discovered that fruit flies use a hormone called corazonin to counteract stress and restore their internal balance. When they are starving or dehydrated, flies use up their energy stores to forage and feed to maintain their internal stable state. These actions are coordinated by corazonin, which also helps flies counteract oxidants. It does this by acting on the fly's liverlike fat body.
