The zinc finger protein ZBTB20 is a morning and evening activity gating factor in mice.

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.

The circadian clock in the model plant organism Arabidopsis thaliana is best described as a highly connected network made up of clock-regulated activators and repressors of transcription, rather than two coupled, repressor-based feedback loops.

Blood-borne factors contribute to changes in the circadian transcriptome with age.

Acetylation of the circadian transcription factor BMAL1 by the acetyltransferase TIP60 is crucial for recruitment of the pause release factors to clock gene promoters and productive elongation of these genes.

Functional imaging and circuit mapping in the Drosophila brain identifies neuropils where sleep-promoting and arousal-promoting neuronal networks converge.

The neuronal calcium sensor Neurocalcin regulates sleep and arousal thresholds during the night in Drosophila.

A multiomic study reveals the role of ZFHX3 transcription factor in daily timekeeping with a combination of transcription factor and histone ChIP-seq and time-resolved RNA-seq in the mammalian central clock.

In zombie fruit flies, Entomophthora muscae-elicited summiting behavior is mediated by blood-borne factors and the host circadian-neurosecretory network.

The circadian clock of Synechococcus elongatus PCC7942 schedules the activity of the transcription factor RpaA, which controls key events in carbon metabolism that contribute to cell fitness in conditions mimicking the natural environment.
