Mass spectrometry has potential as a tool for ecological studies and bioprospecting of natural products from marine cyanobacteria and algae.

Cyanobacteria cope with both predictable day/night changes and natural fluctuations in light during the day by adjusting the expression dynamics of circadian-clock-controlled genes via a network of transcriptional regulators.

The cyanobacterial core clock tracks midday regardless of day length, which can be understood in terms of a model for how the environment alters the clock limit cycle.

The cells of a cyanobacterium act as spherical micro-lenses, allowing the cell to see a light source and move towards it.

Systems level modeling of cyanobacterial mechanism for concentrating carbon dioxide shows optimal organization and enzymatic activity for enhanced carbon fixation.

Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

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.
