NewsMolecular bodyguard helps infections persist
Researchers have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective shield for bacterial genes — and points to new strategies for fighting persistent infections.

NewsEarth’s oxygen boom: a fresh perspective for a billion-year-old problem
A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life.

NewsHow microbial strain variations influence neurobehavior
Microbial single nucleotide variations influence host cognitive behavior by regulating metabolism, a new study of merino sheep reveals.

NewsStudy finds HEPA purifiers alone may not be enough to reduce viral exposure in schools
In a secondary analysis of a study of 200 classrooms, researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.

NewsPoultry growers: Have you checked your water lines lately?
Water quality could impact the kind of microbial populations in poultry drinking water lines and lead to the buildup of a biofilm that can harbor pathogenic bacteria like Salmonella, according to a new study.

NewsProtein condensates determine a cell’s fate, yeast study reveals
To ensure they have all the information they need, molecules from throughout a cell gather and form aggregates that can have different consistencies: regions called “condensates”. Researchers have discovered how condensates contribute to cellular information exchange in yeast cells.

NewsResearchers uncover hidden plant–microbe strategy that boosts crop growth under nutrient stress
Scientists discovered that when soil microbes compete with each other in the rhizosphere, they release a well-known compound called glutathione. This compound enhances plant growth under sulphur-deficient conditions.

NewsBiochar and plants join forces to clean up polluted soils and boost ecosystem recovery
A review explores how combining biochar with rhizoremediation, a nature-based process that uses plant roots and beneficial microbes to break down pollutants, can greatly enhance soil restoration. Biochar acts as both a catalyst and a habitat for microbes.

NewsInspection confirmed mould damage in schools does not increase students’ risk of developing asthma
A recent study found that mould damage in school buildings does not increase the risk of asthma among students. The study included 110 Finnish primary and secondary schools, and the health of 30,000 students was tracked using national health registers over a 16-year period.

NewsMore than a feeling: Could a healthier gut improve mental health?
A new review finds strong causal evidence that gut microbes can change brain chemistry, stress responses and behaviours in animal models; and evidence that probiotics, diet changes, and faecal microbiota transplants improve mood and anxiety.

NewsNew global burden of disease study: Mortality declines, youth deaths rise, widening health inequities
The world faces an emerging crisis of higher death rates in adolescents and young adults in North America and Latin America due to suicide and drug and alcohol consumption, and in sub-Saharan Africa due to infectious diseases and unintentional injuries.

NewsParasite paparazzi take millions of photos of secret malaria proteins
Using millions of microscope images magnified up to 130,000 times, researchers have unraveled the structure of two key proteins in the malaria parasite. With this knowledge, scientists are developing new vaccines that block the transmission of parasites via mosquitoes.

NewsSlime mold metabolites are a promising, eco-friendly repellent of root-knot nematodes
A team of researchers has discovered 14 compounds secreted by slime molds that repel root-knot nematodes (RKNs) - worm-like parasites of the genus Meloidogyne - and could be the source of new, non-toxic anti-RKN pesticides.

NewsRare bacterium ‘plays dead’ to evade detection in NASA clean rooms
A rare novel bacterium found in an unexpected environment may be evading detection by “playing dead”. Discovered in NASA spacecraft assembly clean rooms, Tersicoccus phoenicis could have major implications for planetary protection and clean room sterilization practices.

NewsScientists discover regulatory pathway behind cyanobacteria’s carbon-fixing factories
A new study illuminates a key regulatory pathway between cyanobacteria’s light-harvesting systems and the inner compartments where carbon fixation happens, helping us to understand how cyanobacteria balance their energy demands.

NewsLittle-known strep bacteria behind growing number of severe infections
An under-recognised strep bacterium is causing a growing number of serious infections in Australia, with First Nations Australians disproportionately affected, according to new research.

NewsWastewater plants produce twice as much greenhouse gases as officially estimated
Wastewater plants emit about twice as much greenhouse gas as previously believed, according to a new study. Collectively sewer plants produced 1.9 times the nitrous oxide gas estimated by the Environmental Protection Agency and 2.4 times the methane.

NewsResearch team with the latest Nobel Prize laureate reveals regulatory immune cell precursors disrupted in severe COVID-19
A research team joined by Professor Shimon Sakaguchi – the latest Nobel Laureate in Physiology or Medicine – has identified a subset of immune cells called precursor T follicular regulatory cells (preTfr) that play a critical role in preventing autoantibody production.

News1,000-year-old gut microbiome revealed for young man who lived in pre-Hispanic Mexico
Analysis of preserved feces and intestinal tissue has revealed specific types of bacteria that were present in the microbiome of a young adult man who lived in Mexico about 1,000 years ago, prior to Spanish colonization.

NewsDeadwood-decomposing fungi feed germinating orchids
Deadwood-decomposing fungi feed germinating orchids, providing the carbon their tiny seeds don’t have. The finding not only closes a gap in our understanding of wild orchid ecology but also uncovers an important carbon flux in the ecosystem.
