When fruit flies are hungry, they become especially attuned to the scent of their next good meal, according to a report in the April 1st issue of Cell, a Cell Press publication. That sensory and behavioral shift can be traced to insulin and to a neuropeptide already familiar in humans for its effects on a brain region that controls appetite.
