Bacteria and archaea use protein filament systems to organize cellular processes in time and space. Filaments can act as static scaffolds or as dynamic motors. In some cases, these filament systems ...

The distribution of prokaryotic abundance (PA), respiratory activity (ETS), heterotrophic production (PHP), and suspended particulate (POM) and dissolved (DOM) organic matter was determined in the ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

New insights have been gained from the most comprehensive tree of prokaryotic life assembled to date, report scientists. Bacteria were the original masters of their domain, having Earth to themselves ...
