For resetting circadian rhythms, neural cooperation is key

Fruit flies are pretty predictable when it comes to scheduling their days, with peaks of activity at dawn and dusk and rest times in between. Now, researchers reporting in the Cell Press journal Cell Reports on April 17 have found that the clusters of brain cells responsible for each of those activity peaks -- known as the morning and evening oscillators, respectively -- don't work alone. For flies' internal clocks to follow the sun, cooperation is key.
