Behavior Wakeful Smells in the Morning
It is hard to sleep late when your household is up and about at the crack of dawn. Such social influences are seen in other animals, but how are these signals communicated? Levine et al. have examined mixed Drosophila populations of wild-type (rhythmic) and short-period (arrhythmic) flies and found that arrhythmic flies destabilize the rhythms of wild-type flies. The information seems to be communicated by chemosensory cues: flies that lack the ability to sense chemical signals ignored their neighbors' activity.
