How fruit flies chase invisible ribbons of smell to get to their source

Scientists studying fruit flies found that the insects navigate odor plumes by following invisible ribbons of scent through turbulent air, relying on directional sensing and memory to locate the source. Research published on this topic involved tracking how fruit flies respond to odor dispersal patterns rather than simply detecting individual scent molecules. The study demonstrated that fruit flies adjust their flight paths based on the direction and intensity of smell cues they encounter.
