The influence of environmental noise on circadian gene expression in Drosophila

Circadian rhythm is an important biological signal that regulates many behavior, physiology or cellular processes. This work find light noise can apparently influence the rhythm regularity but the rhythm period is relatively stable to it. The noise can play a constructive role to minimize its destructive effect on the rhythm regularity. There is always a worst noise intensity that the regularity is the most dramatically destroyed, however, even stronger noise can counterintuitively minimize this destructive effect.
