NewsFrom gut to lung: A microbial signal that strengthens early immune defense
Researchers report that a gut microbiota–derived metabolite can directly shape immune responses in bacterial pneumonia. Using a Klebsiella pneumoniae infection model, the team demonstrated that butyric acid restores the function of CX3CR1-positive natural killer cells.

NewsHow periodontitis-linked bacteria accelerate osteoporosis-like bone loss through the gut
Researchers reveal that salivary bacteria from gum disease alter gut metabolism, driving osteoclast activity and systemic bone loss. They analyzed salivary microbiota from individuals with advanced periodontitis and compared them with samples from periodontally healthy donors.

NewsGut microbiome connected with heart disease precursor
Before the onset of cardiovascular disease symptoms, people often develop dyslipidemia, or abnormal levels of lipids in the blood. Microbiologists have identified microbial taxa more likely to be found in people with dyslipidemia than in people with healthy levels of cholesterol and triglycerides.

NewsAntibacterial coatings with short-term effect may fail over longer periods of time
Researchers have shown that antibacterial coatings which initially appear highly effective at destroying bacteria may lose their performance over time. Therefore, long-term testing is essential for developing the best antibacterial materials.

NewsTargeting the gut–lung microbiome to reduce infections in severe pancreatitis
Researchers report new clinical evidence that a fungal probiotic may reduce hospital-acquired infections in patients with severe acute pancreatitis. Patients receiving Saccharomyces boulardii alongside standard enteral nutrition experienced significantly fewer infections than those receiving nutrition alone.

NewsResearchers identify ‘neuroimmune signature’ that can predict viral hepatitis complications
A network of genes linked to the nervous and immune systems can predict cancer risk and even explain symptoms such as fatigue and depression resulting from viral hepatitis infection.

NewsBacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. A new study shows for the first time how gut bacteria break down parts of an allergenic food and influence how a person reacts to peanuts.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.

NewsProlonged drought linked to instability in key nitrogen-cycling microbes in Connecticut salt marsh
A prolonged drought in southeastern Connecticut reduced the stability of microorganisms responsible for a critical step in the nitrogen cycle in a coastal salt marsh, according to new research.

NewsUnderground fungal map of the world’s oldest, slowest-growing rainforest trees can boost the resilience of Earth’s long-term carbon sinks
Protecting and conserving old trees will protect hundreds, if not thousands, of mycorrhizal and other fungal species that inhabit soils around these giants, each of which play a role we might not fully understand in keeping these forests healthy and resilient.

NewsResearchers find a gentler way to treat aggressive gum disease
Researchers have discovered that the primary bacterium driving gum disease carries an internal “genetic brake” that controls its own aggression. By locking this brake in place, future treatments could silence the pathogen while leaving beneficial bacteria untouched.

NewsBiodegradable mulch isn’t disappearing as expected, new study warns
Scientists investigated how soybean roots influence the degradation of PBAT microplastics in soil. They tracked both polymer loss and monomer accumulation over a full 70-day plant growth cycle, revealing size-dependent and condition-specific rhizosphere effects.

NewsEditing for timing, not overdrive: A new genetic route to fire blight resistance in apple
Fire blight remains one of the most destructive bacterial diseases threatening global apple production. A new study identifies a family of inducible lectin genes, MdAGGs, as critical components of apple immune defense and demonstrates that their precise activation timing is key to effective resistance.

NewsA common CRISPR platform enables comparative studies of multicellularity in social amoebae
Researchers have established a CRISPR genome editing technique that enables comparative analysis of the evolution of multicellularity across different species of social amoebas (cellular slime molds). Until now, genetic studies had been largely restricted to a single model species.

NewsAncient symbiosis between plants and fungi: Important insights for sustainable agriculture
Almost all plants live in close symbiosis with so-called mycorrhizal fungi – an important symbiosis for absorbing essential nutrients. Scientists have discovered that this mycorrhizal symbiosis is very sensitive to imbalances of certain nutrients in the soil.

NewsTiny plastics, green solutions: How algae could help clean polluted waters
A new review examines how algae interact with microplastics in aquatic systems. Importantly, it highlights how their biological interactions could be harnessed to mitigate microplastic pollution, offering new perspectives for sustainable aquatic environmental management.

NewsDiisobutyl phthalate at environmental concentration promotes conjugative transfer of antibiotic resistance genes
Researchers investigating the ecological safety risks posed by dibutyl phthalate (DBP), in aquatic environments found it significantly increased conjugative transfer frequency in both intragenus (E. coli DH5α to E. coli HB101) and intergenus (E. coli DH5α to B. subtilis WB100N) systems.

NewsToxic algal bloom takes heavy toll on mental health
The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.

NewsBig and small dogs both impact indoor air quality - just differently
An initial study reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.

NewsLife forms can planet hop on asteroid debris – and survive
The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact, a study shows. It means microorganisms can survive more extreme conditions than previously thought, including launch across space after major impacts.
