Resilient circadian oscillator revealed in individual cyanobacteria
Article Abstract:
Circadian rhythms and their stability in unicellular cyanobacteria Synechoccocus elongatus are studied. Studies indicate that the oscillators are having a strong temporal stability with a correlation time of several months and this stability seems to be ensured by the intracellular biochemical network, because the interactions between oscillators in different cells seem to be negligible.

Circadian clocks limited by noise
Article Abstract:
Circadian rhythms are used by many organisms to anticipate changes in the environment. A circadian network is shown to oscillate in the presence of stochastic bio-chemical noise, and it is proposed that the ability to resist such perturbations places strict limits on the oscillation mechanisms underlying circadian periodicity.

As time glows by in bacteria
Article Abstract:
Cyanobacteria also known as blue-green algae, is a new model system for the analysis of circadian rhythms in single cells. Results indicate that these 'simple' bacteria have circadian systems that are stable in the face of the cell division, intracellular noise and altered metabolic conditions that occur as a colony grows.
