Biological rhythms: Clocks for all times

The development and harmonious functioning of an organism depend on the exquisite coordination of myriad intertwined biological processes. As illustrated by this issue of Current Biology devoted to the ‘biology of time’, temporal organization plays crucial roles in coordinating dynamic phenomena as diverse as progression through the cell cycle, the processing of information, adaptation to the periodic environment, and the response to extracellular or intracellular signals. Here I will focus on one of the most conspicuous manifestations of temporal organization, that which takes the form of rhythmic behavior.
