Cyanobacteria and diatoms assimilate some of the organic sulfur produced by other phytoplankton and thus prevent its release to the atmosphere where it would otherwise influence climate.

Centrosomal proteins are important for cell cycle progression, but their role does not require their presence in the centrosome itself.

Morphology is strikingly at odds with molecular data for classification of cellular slime molds, suggesting that a full revision of their phylogeny is needed.
