Fruit fly's response to starvation could help control human appetites

Biologists have identified the molecular mechanisms triggered by starvation in fruit flies that enhance the nervous system's response to smell, allowing these insects and presumably vertebrates -- including humans -- to become more efficient and voracious foragers when hungry. Their discovery of the neural changes that control odor-driven food searches in flies could provide a new way to potentially regulate human appetite.
