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.

NewsTestosterone increases severity of bacterial skin infections
Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study is the first to reveal testosterone, present at higher levels in males, as a key driver of infection.

NewsUltrasound-activated ‘nanoagents’ kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug‑delivery capsules – carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound.

News10 Years, 70% shift: Wastewater upgrades quietly transform river microbiomes
Researchers investigated how the upgrade of a WWTP influenced nitrogen-cycling microorganisms and DNA viruses in its receiving river. The research compared the river whose WWTP was upgraded during the study period against the river whose upgrade occurred prior to the study.

NewsCell-free DNA offers early warning for bloodstream infections in kids with leukemia
Researchers show that microbial cell-free DNA sequencing can predict bloodstream infections in children with leukemia days before the symptoms appear. Plasma microbial cell-free DNA sequencing (mcfDNA-Seq) offer a potential approach to protecting vulnerable patients by allowing treatment to start before the patient gets sick.

NewsAkkermansia muciniphila PROBIO therapy promotes arginine biosynthesis and reverses reproductive impairments in polycystic ovary syndrome rats
A research study investigated the therapeutic potential of Akkermansia muciniphila PROBIO (AP) in a dehydroepiandrosterone-induced PCOS rat model, revealing significant improvements in reproductive and metabolic parameters through modulation of gut microbiota and enhancement of arginine biosynthesis.

NewsMicrobes unlock a hidden natural source of mercury emissions from ‘stable’ minerals
A new study reports a previously overlooked natural mechanism that could contribute substantially to global mercury emissions. Researchers show that chemolithoautotrophic microbes can use mercury sulfide nanominerals as an energy source and, in the process, release volatile Hg0 into the air.

NewsScientists develop new gut health measure that tracks disease
Scientists have found that healthy and diseased digestive systems behave like two distinct ecological states, driven not by individual microbes but by how entire bacterial communities compete and cooperate.
-
NewsNanoplastics can interact with Salmonella to affect food safety, study shows
Researchers investigating what happens when nanoplastics (polystyrene) interact with Salmonella discovered an increased expression of virulence-related genes. The bacteria also formed thicker biofilms, which indicates they are becoming more virulent.

NewsBacterial cellulose as a sustainable vehicle for the controlled release of nisin and mandelic acid: A clean beauty-based approach for acne treatment
A new study developed a bacterial cellulose-based delivery system loaded with nisin and mandelic acid, targeting acne treatment. Bacterial cellulose, derived from Komagataebacter xylinus, served as a biocompatible, biodegradable matrix to control the release of bioactive compounds.

NewsTrust your gut to heal your brain
Researchers have found that short-term antibiotic treatment significantly reduced neuroinflammation and neurodegeneration following traumatic brain injury (TBI) by altering the gut microbiome in animal models.

NewsFe₃O₄@mPEG-Ag nanoparticles: a new frontier in combating antibiotic resistance
A collaborative study introduces Fe₃O₄@mPEG-Ag nanoparticles (NPs) as a groundbreaking non-antibiotic strategy to combat drug-resistant bacteria, offering the antibacterial properties of silver (Ag) with the stability and biocompatibility of magnetite (Fe₃O₄) modified by methoxy poly(ethylene glycol) (mPEG).
