NewsEject! Bacteria discovered with the ability to jettison cells as a survival mechanism
Biologists have found that communities of bacteria are capable of ‘escape pod’ ejection strategies. They documented the biofilm ejection phenomenon for the first time while studying a bacterium known as hay bacillus (Bacillus subtilis).

NewsFighting the world’s deadliest infection with PAC-MAN and AI
Researchers have developed techniques that can speed up the search for better tuberculosis drugs. They first measure which chemical compounds are able to slip across the outer membrane and then use those measurements to predict other compounds that can get into the Mtb cell.

NewsGentian receives carbon through mycorrhizal fungi in addition to photosynthesis
Researchers have found that Gentiana squarrosa Ledeb. is partially mycoheterotrophic. The plant not only produces carbon through photosynthesis but also receives carbon through underground fungal networks.

NewsMicrobe-mapping project transforms entire university campus into a “living lab”
An innovative citizen science project is combining large-scale microbe sampling with metagenomics workshops and utilising the power of students to map out the varied microbiomes of the University of Milano-Bicocca’s campus - including those within the students themselves. Source: Giulia Ghisleni and Antonia Bruno Student sampling microbes from ...

NewsTuberculosis vaccine changes brain’s immune environment and Alzheimer’s biomarkers in older adults
A study shows that BCG vaccines can alter immune responses and amyloid-beta biomarkers in non-Alzheimer’s participants, which may help explain previously observed links to lower disease risk.

NewsResearchers identify a marine bacterial enzyme that opens a new route to build bioactive compound libraries
A research team has provided new insight into HapC, an enzyme from the marine bacterium Hahella chejuensis. They used modified short-chain versions of one key chemical building block and examined whether HapC could join them with another precursor to form new prodiginine compounds.

NewsHow psychological stress alters gut microbes and ages blood stem cells in mice
Psychological stress is recognized as a risk factor for certain health conditions. Researchers describe a mechanism in mice that explains this association: psychological stress speeds up aging-like changes in the body’s blood-forming stem cells in the bone marrow by altering the intestinal microbiota.

NewsPlant DNA harbours virus ‘fossils’ that reflect 300 million years of evolution
New research shows that Caulimoviridae viruses have infected an extremely wide range of vascular plant hosts, from lycophytes to flowering plants, revealing the existence of 35 previously undescribed taxonomic clusters in Caulimoviridae.

NewsThe broader a fungus’s diet, the better it kills insects and helps plants
Entomologists have discovered that a single underlying trait—metabolic breadth, or the range of nutrients a fungus can use—links its ability to kill insects, partner with plants and thrive in different ecological roles.

NewsA subtle difference offers insight into bacteria survival strategies
Researchers have discovered that Bacillus subtilis employs a different survival strategy to E coli, raising the question of whether other types of bacteria use alternative strategies, and how this might help researchers think differently about antibiotic tolerance.
