The Blau Lab published a paper in the September issue of PLOS Biology in which they described how clocks in individual neurons synchronize with each other for a coherent internal timer. They found this is a surprisingly active process, requiring distinct signals at dusk and dawn for full synchrony. Synchronized circadian clocks are important for normal sleep/wake cycles - at least in Drosophila.
This work was also reported in the New York Times.
