#Cyanobacterial blooms are becoming more frequent and severe as a result of climate change, according to the Charles River Watershed Association.

“Excess #phosphorus from stormwater runoff and warmer temperatures cause cyanobacteria populations to explode into a toxic bloom,
releasing dangerous #cyanotoxins that threaten public health,
are fatal to pets,
and are harmful to the ecosystem,” according to the association.

The source of #paleozoic (hemi-) #pelagic calcareous #mud (before the rise modern pelagic calcifiers) has been bugging me, again, recently.
I have seen arguments for calcification of #cyanobacterial filaments, calcareous #dinoflagellates, breakdown of thin-walled fossils, and I'm not negating #abiotic sources.

Does anyone have any thoughts on the topic?

Researchers report the high-res structure of a little-known cyanobacterial virus

A research team at the Hong Kong University of Science and Technology (HKUST) has outlined the high-resolution structure of a little-known virus, improving our understanding of viral infection, which could pave the way for more accurate predictions of climate change.

Examining the role of 'blind dating' in bacteria evolution

Proteins are the key players for virtually all molecular processes within the cell. To fulfill their diverse functions, they have to interact with other proteins. Such protein-protein interactions are mediated by highly complementary surfaces, which typically involve many amino acids that are positioned precisely to produce a tight, specific fit between two proteins. However, comparatively little is known about how such interactions are created during evolution.
