NewsBacterial energy model reveals how antimicrobial resistance (AMR) spreads in environment
Researchers analyzed how bacteria in aquatic environments distribute energy across diverse functions such as growth, biofilm formation, conjugative transfer of antimicrobial resistance genes and heavy‑metal tolerance, to clarify bacterial energy investment strategies.

NewsProbiotic living microneedles designed by interbacterial competition for accelerated infected wound healing
Probiotic therapy offers a promising strategy for chronic infected wound management. Inspired by bacterial competitive interactions, researchers developed a multifunctional microneedle (MN) platform to overcome the limitations of weak competitiveness and poor penetration across biofilm barriers.

NewsBiodegradable and conventional plastics shape very different antibiotic resistance risks in river microbiomes
Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river.

NewsA new ally against tooth decay: Arginine offers sweet relief
A new human clinical trial finds arginine can prevent caries due to bacterial plaques by reducing the acidity, altering the plaque structure and reducing harmful bacteria in the plaques.

NewsPresurgical vaccine may prevent orthopedic device infections
Researchers have developed a novel presurgical vaccine strategy that may prevent dangerous infections in patients receiving hip, knee, and other joint replacements, creating an injectable scaffold designed to stimulate the immune system.

NewsPlant extracts show promise in reducing human pathogen risks in agricultural soils
A new study has revealed that natural plant extracts can significantly lower the risks posed by human bacterial pathogens in manure amended agricultural soils. The eco friendly strategy disrupts the communication systems that bacteria use to coordinate harmful activities.

NewsNobel Prize-awarded material that punctures and kills bacteria
Bacteria that multiply on surfaces are a major headache in healthcare. Researchers have found a new weapon to fight these hotbeds of bacterial growth – metal-organic frameworks. These materials can physically impale, puncture and kill bacteria before they have time to attach to the surface.

NewsAcid rain may be training soil bacteria to become more deadly
Acid rain from fossil fuel pollution may be quietly training soil bacteria to become longer-lived, more transmissible, and more deadly, according to a new study that tracks how a notorious foodborne pathogen rapidly evolved under simulated acid deposition.

NewsMicroplastics pose a human health risk in more ways than one
A new study shows that microplastics in the natural environment are colonised by pathogenic and antimicrobial resistant bacteria. The study team calls for urgent action for waste management and strongly recommends wearing gloves when taking part in beach cleans.

NewsNew nanogel technology destroys drug-resistant bacteria in hours
A novel technology shows over 99.9% effectiveness against Pseudomonas aeruginosa (P. aeruginosa). It centres on a heteromultivalent nanogel: a flexible particle made by crosslinking polymers and adding sugar residues (galactose and fucose) alongside antimicrobial peptides.

NewsBacteriophage characterization provides platform for rational design
Researchers have described the bacteriophage Bas63 in unprecedented detail, supporting new mechanistic understanding of how these viruses function.

NewsSecrets of microbial motion: How bacteria swash, glide and shift gears to survive
Two new studies reveal surprising ways microbes move, with implications for human health and disease. The first shows that salmonella and E. coli can ’swash’ across moist surfaces even when their flagella are disabled, while the second probes the T9SS gearbox in flavobacteria.

NewsHarnessing solar energy for environmental cleanup: Iron mineral-bacterial biofilms degrade pollutants
Researchers offer a sustainable, efficient, and scalable method for addressing soil and groundwater pollution, opening new possibilities for clean-up strategies in diverse ecosystems. This process significantly enhances the degradation of antibiotics like tetracycline hydrochloride (TCH) and chloramphenicol (CPL).

NewsData-guided bioelectrodes pave way for greener remediation
There is an urgent need to develop data-driven strategies that can accelerate and scale up microbial dechlorination for contaminated environments. Researchers report a new machine learning framework that integrates experimental features with microbial biofilm data to optimize bioelectrodechlorination.

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.
-
NewsSoil bacteria and minerals form a natural ‘battery’ that breaks down antibiotics in the dark
Researchers have unveiled a surprising new way that soil microbes can use sunlight energy. The team developed a “bio-photovoltage soil-microbe battery” that can capture, store, and release solar energy to power the breakdown of antibiotic pollutants in the dark.

NewsResearchers wake up microbes trapped in permafrost for thousands of years
In a new study, a team of geologists and biologists resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years.

CareersSummer studentship: Amelia investigates how Streptococci aggregate with other oral bacteria
Amelia Rohim reports back on her AMI-sponsored summer studentship which focused on the investigation of inter-species aggregation between oral bacteria at the University of Michigan with Dr. Alexander Rickard.

NewsPlant-derived compound has antimicrobial and anti-inflammatory effects against periodontal disease
Morin-based powder, extracted from guava leaves, apple peel, and figs, can be slowly released with the help of polymers and serve as an alternative to antibiotics.

NewsCan the ‘good’ bacteria in your mouth act as probiotic cavity fighters?
Discovery of clumping molecules made by gene clusters in the oral microbiome may lead to ways to reengineer the microbes in plaque, a new study shows.
