There are millions of species of bacteria and archaea on Earth, remarkably little is known about most of them. Now, researchers have mined the genomes of thousands of microorganisms preserved at the RIKEN BioResource Research Center (BRC) to find organisms that may be capable of capturing CO2. BRC, located in Tsukuba—one of Japan's largest centers of scientific research—is a unique, world-class research facility. https://phys.org/news/2026-09-microbial-dark-yields-potential-carbon.html Cell & Microbiology Thu, 03 Sep 2026 11:40:09 EDT news707649132 Communication between cells in plants, animals and humans takes place via specialized connecting structures. An international team led by biologists from Heinrich Heine University Düsseldorf (HHU) and involving the University of Tübingen has now discovered that the regulation of very similar structures was already present in multicellular bacteria, implying that it must have originated much earlier in the course of evolution. In their paper published in The EMBO Journal, the researchers describe how the exchange of calcium plays a central role in bacteria, just as it does in humans. https://phys.org/news/2026-08-ancient-bacteria-intercellular-communication-humans.html Evolution Mon, 31 Aug 2026 19:00:05 EDT news707406962 Salty water flowing through Antarctica's Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin, according to a paper published in Nature Geoscience.

It turns out the viruses most busy at night were not infecting bacteria that perform photosynthesis, which are among the types of bacteria known to be infected by viruses. Instead, these overnight viral hosts were microbes that focus on consumption of other organic matter because they can't produce their own food. https://phys.org/news/2026-03-glimpse-viral-dark-sargasso-sea.html Ecology Tue, 31 Mar 2026 15:00:07 EDT news694179001 Marine fouling triggers ongoing economic losses for the global shipping industry through detrimental effects on structures and vessels—but tests by Flinders University researchers on a new type of anti-foul coating reveal a solution that is not detrimental to the environment. https://phys.org/news/2025-12-eco-friendly-solution-marine-fouling.html Analytical Chemistry Mon, 15 Dec 2025 11:35:25 EST news685020902 Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, revealing how this essential mitochondrial enzyme degrades RNA through an elegant base-flipping mechanism. https://phys.org/news/2025-12-mitochondrial-enzyme-atomic-reveals-rna.html Cell & Microbiology Wed, 10 Dec 2025 16:32:19 EST news684606715 A research team led by Prof. Sun Chaomin from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has unveiled the crucial role of viruses in deep-sea carbon cycling and microbial community structure.
