Noisy circadian clocks in Anabaena, coupled by cell-cell communication, display high spatio-temporal coherence and can be robustly described by incorporating demographic noise in a theoretical model of coupled clock arrays.

Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.

Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

A ménàge à trois introduces extra DNA only to plant embryos, thus skipping endosperm-induced seed hybridization barriers.

A gene that codes for a transcription factor that is involved in lipid and carbohydrate metabolism also has a role in the regulation of circadian rhythms.

The first epigenetic clock for rats was developed and revealed to reflect phenotypic aging and captured the effects of longevity interventions.

The temperature-sensitive protein CIRBP contributes to the effect of sleep loss on the molecular circadian clock.

Cyclin-dependent kinase 5 regulates the circadian clock involving phosphorylation of the PER2 protein.

A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.

RNA sequencing reveals the finer details of circadian variation in the mammalian master pacemaker over 24 hours, which suggests that transcriptional timing influences clock resetting mechanisms.
