NewsCholera vaccine completes phase 1 trial
A clinical trial shows promising results for PanChol, a single-dose oral vaccine aimed at the up to 4 million annual cholera cases worldwide.

NewsSub-lethal water disinfection may accelerate the spread of antibiotic resistance
A new study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.
-
NewsSome antibodies outmaneuver germs from sticking to cells
Researchers have uncovered several new mechanisms by which antibodies block E. coli bacteria that cause urinary tract infections from attaching to bladder cells. Once E. coli bacteria get a strong grip, they can be difficult to flush out.

NewsNew study uncovers how rice viruses manipulate plant defenses to protect insect vectors
Rather than passively “hitchhiking” within insect vectors, rice viruses actively manipulate plant defense pathways to protect their insect carriers.

NewsRibosomal engineering creates ‘super-probiotic’ bacteria
Using ribosome engineering (RE), researchers introduced mutations affecting the protein synthesis mechanism of probiotic Lacticaseibacillus rhamnosus GG (LGG). These mutant LGGs exhibit altered surface protein expression, including increased presentation of so-called “moonlighting proteins.”

NewsFrom sediment to surface: How invisible plumes trigger harmful algal blooms
A new study shows that algal blooms can begin days earlier than previously recognized, originating from chlorophyll-rich plumes rising from lake sediments before any surface discoloration appears.

NewsPlant-derived phenolic acids revive the power of tetracycline against drug-resistant bacteria
A study demonstrates that plant-derived phenolic acids can act as powerful antibiotic adjuvants by restoring and enhancing tetracycline efficacy against multidrug-resistant bacteria through multi-target disruption of key resistance mechanisms.

NewsViruses in wastewater: Silent drivers of pollution removal and antibiotic resistance
New findings suggest that current monitoring strategies, which rely heavily on bacterial indicators alone, may miss critical viral-driven risks and opportunities for safer wastewater reuse.
-
NewsCRISPR discovery could lead to single diagnostic test for COVID, flu, RSV
Researchers report newly discovered details about the Cas12a3 immune system that precisely targets transfer RNA in invading pathogens, without destroying host cells.
-
NewsStudy identifies a molecular switch that controls transitions between single-celled and multicellular forms
How did multicellular life evolve from single cells? Researchers have identified genes in marine yeast that may help answer this fundamental question.
-
NewsFatal infection risk in newborns may increase when this bacteria and fungus mix
A new study reveals that when Streptococcus agalactiae (GBS) interacts with Candida albicans, GBS is more likely to spread disease and become harder to treat in newborns. Infection by both microbes reduces the effectiveness of existing GBS treatments.
-
NewsDiscovery could lead to new treatments for drug-resistant fungal infections
Researchers have identified a molecule that may help turn the tide on fungal infections — butyrolactol A, a chemical compound that targets a deadly, disease-causing fungi called Cryptococcus neoformans.
-
NewsInternational experts connect infections and aging through cellular senescence
Researchers propose the concept of infection-driven senescence (IDS) to describe the phenomenon in which microbial agents, beyond viruses, can trigger cellular senescence in host cells.
-
NewsResearchers eye goal of turning garden and crop waste into plastics
A research team will combine eco-friendly and application-oriented approaches to develop a cost-effective, energy-efficient technology for making innovative plastics based on polybutylene succinate (PBS) which are made entirely out of organic waste.

NewsScience army mobilizes to map US soil microbiome
A small army of researchers are working to catalog the vast and largely unknown soil microbiome of the United States. The project, one of the biggest microbiome studies ever attempted, has already resulted in the discovery of more than 1,000 new strains of bacteria and never-before-seen microbes.

NewsNew clinical standards strengthen antimicrobial stewardship in tuberculosis care
An international panel of experts from 32 countries has presented specific antimicrobial stewardship standards for TB care for the first time.

NewsNew evidence reveals Streptococcus anginosus drives gastric cancer development
A recent study has revealed a novel cancer-promoting mechanism of Streptococcus anginosus. The research shows that methionine metabolites produced by this bacterium can significantly contribute to the development of gastric cancer.

NewsNew database to target chronic UTIs – a long-overlooked condition that may begin in childhood
A new database targeting chronic urinary tract infections (UTIs) – a long-overlooked condition that may begin in childhood – is set to help researchers uncover why millions of women and girls worldwide suffer from infections that defy treatment and stump microbiologists.

NewsHow the parasite that ‘gave up sex’ found more hosts – and why its victory won’t last
A study has revealed a genetic shortcut that may help Giardia duodenalis and many other parasites jump to new hosts at the cost of long-term survival. The findings may also help explain how parasites evolve drug resistance.

NewsRice genes matter more than domestication in shaping plant microbiomes
A new study reveals that the specific genetic identity of a rice plant plays a stronger role than whether it is wild or domesticated in determining which microbes it hosts and how those microbes function.
