NewsNew studies reveal how Clostridioides difficile behaves inside the body
Researchers studying C. diff at multiple levels, from how individual bacterial cells behave inside the gut to the molecular switches that help them survive and spread, are revealing hidden vulnerabilities.

NewsNew compound stops common complications after intestinal surgery
Researchers have synthesized and tested a new compound in mice that shows promise in protecting the liver from damage and improving nutrient absorption after small bowel resection. They also found that the drug works only on the gastrointestinal tract.

NewsScientists engineer ‘living eye drop’ to support corneal healing
A proof-of-concept study demonstrates that the harmless eye-dwelling microbe Corynebacterium mastitidis can be genetically modified to secrete an anti-inflammatory therapeutic that promotes healing following corneal injury in a mouse model.

NewsHow microbes protect the lungs against allergies
A study has revealed that microbes protect the lungs from subsequently developing allergies and asthma. This long-term protection is “memorized” not by immune system cells but by fibroblasts, structural cells in the lungs.

News Natural dye produced by Amazonian fungus can be used in cosmetics
A red extract made from Talaromyces amestolkiae was tested in the bases of potential products, including face cream, shampoo, and gel sticks, for its antioxidant and antibacterial properties.

NewsStudy reveals how gut bacteria and diet can reprogram fat to burn more energy
A new study shows that a low‑protein diet activates a precise set of gut microbes that send chemical signals throughout the body, prompting fat tissue to burn energy instead of storing it. The findings uncover a previously unknown biological pathway linking diet, the gut microbiome and metabolic health.

NewsNitrous oxide, a product of fertilizer use, may harm some soil bacteria
While some nitrous oxide is produced naturally at the plant root, agricultural practices can increase its levels. While it has long been believed that nitrous oxide doesn’t meaningfully interact with living organisms, a new paper shows that it may in fact shape microbial communities.

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.
-
NewsScientists develop shape-shifting scaffold that fights infection and rebuilds bone
Scientists have developed a body-temperature–responsive, 3D-printed shape-memory scaffold coated with a metal–polyphenol network to treat infectious bone defects. It is designed to adapt to irregular bone defects while providing antibacterial activity, immune regulation, and osteogenic support.

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.

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.
-
NewsChemically ‘stapled’ peptides used to target difficult-to-treat cancers
Researchers have developed a new technology that uses bacteria to build, chemically stabilise, and test millions of potential drug molecules inside living cells. The bacteria produce vast libraries of peptide molecules, and chemically stabilise them into defined shapes while they are being tested inside the cell.

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.

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.

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.

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.
