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).

NewsPeople’s gut bacteria worse in areas with higher social deprivation
Living in a poorer neighbourhood in the UK could impact the make-up of your gut microbiome, potentially leading to worse health. New research found that people living in areas of higher social deprivation have a less diverse range of bacteria in their gut.

NewsScientists uncover mechanism used by three bacteria-killing viruses to target transporter
Biochemists have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria use to build their chain-mail-like cell wall. Using advanced tools, the scientists have determined the common mechanism used by three different bacteria-killing viruses to block MurJ from doing its job.

NewsScientists identify endangered natural pharmacy hidden in coral reefs
The magnitude of the potential loss of the “natural pharmacy” found in the coral microbiome is demonstrated by a new study which identified new microbial species in corals which have the ability to produce novel substances.

NewsScientists uncover how engineered biochar and microbes work together to boost plant-based cleanup of cadmium-polluted soils
A new study reveals how specially modified biochar can significantly improve the ability of willow trees to remove toxic cadmium from contaminated soils, offering a promising strategy for restoring polluted land in a sustainable way.

NewsEmerging class of antibiotics to tackle global tuberculosis crisis
Researchers investigated how three naturally occurring antibiotic compounds – ecumicin, ilamycin and cyclomarin – act on a vital protein degradation machine inside Mycobacterium tuberculosis, the bacterium that causes TB.

NewsMeningococcal B vaccination does not reduce gonorrhoea, trial results show
Contrary to existing evidence from observational studies, the meningococcal B vaccine (4CMenB) has no effect on preventing the acquisition of gonorrhoea, according to the results of the world’s largest randomised control trial (RCT) into possible efficacy.

NewsHidden architecture inside cellular droplets reveals new targets for cancer and neurodegeneration
Cells rely on biomolecular condensates to coordinate essential biological processes without surrounding membranes. Scientists long assumed condensates lacked internal organization and functioned as a simple liquid, but a new study has discovered that some are built from intricate networks of thread-like protein filaments.

NewsStudy finds no evidence of persistent tick-borne infection in people who link chronic illness to ticks
When researchers studied Norwegians who thought tick bites caused their chronic health problems, they found no objective evidence linking the symptoms to ticks. The same study finds that health problems reported by participants were associated with little physical activity and low labour force participation.

NewsA new ecological model highlights how fluctuating environments push microbes to work together
A new study explores why interdependence can be a winning move for microbial communities. It demonstrated that a mathematical model of how bacteria produce and share resources accurately predicted the outcome of experiments with living E. coli strains.
