Cells possess internal ~24 hr or circadian clocks that synchronize physiological processes with daily cycles of light and nutrient availability. In this issue, Asher et al. (2010) find that PARP-1 (poly(ADP-ribose) polymerase 1) modifies components of the clock machinery in response to feeding, providing a mechanism for how metabolic rhythms coordinate with circadian rhythms.
