NewsCopper-loaded starch nanoparticles can target bacteria in microbial communities
Researchers have developed copper-loaded starch nanoparticles that can be broken down by specific bacteria to release antibacterial copper molecules. They hope that these nanoparticles can be used to target biofilms, which account for 50-70% of healthcare-associated infections.

NewsNew vaccine strategy could help extend immunity against evolving viruses
Researchers have identified a possible way to make longer lasting vaccines for respiratory viruses like influenza and the coronavirus that causes COVID-19.

NewsVitamin D linked to immune response to gut microbiome in inflammatory bowel disease
Vitamin D supplementation may help shape how the immune system responds to gut bacteria in people with inflammatory bowel disease (IBD), according to a new study.

NewsWhen algae stop growing, bacteria start swarming
A new study describes how a recently identified species of marine bacteria targets diatoms based on growth phase and nutrient availability.

NewsStudy reveals how a live bacterial therapy reshapes the vaginal microbiome and identifies predictors of treatment success
A new study provides the most detailed picture yet of how a promising bacterial therapy works to prevent recurrent bacterial vaginosis (BV) and why it works better for some women than others.

NewsScientists studying bird flu in the air to protect people and agricultural operations
New research will investigate how nonthermal plasmas can render aerosols containing the virus that causes bird flu incapable of infecting humans and livestock. The approach exposes air to strong electric fields, temporarily creating free electrical charges that damage viruses.

NewsAging lung cells could be why COVID and flu are so dangerous to the elderly
Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers.

NewsFiber in whole wheat foods protects against gut inflammation in mice, study finds
Enriching the diet with wheat fiber protects mice against intestinal inflammation, according to a study. The finding helps explain why incidence of inflammatory bowel disease (IBD) has increased, and suggests eating whole wheat foods may reduce one’s risk of developing it.

NewsScientists identify new Fusarium species behind wheat disease outbreak in Ethiopia
New research provides new insights into the severe 2022 outbreak of Fusarium head blight in Ethiopia and identifies emerging fungal pathogens that could have broader implications for global wheat production.

NewsRNA-guided CRISPR system activates gene expression
In back-to-back studies, researchers report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing systems that merely find and cut DNA.

NewsFirst Chagas disease conference on US soil highlights a turning point in national awareness
For the first time, a conference dedicated to Chagas disease research will be held on U.S. soil, marking a significant and symbolic moment for researchers, clinicians and public health leaders working to boost awareness of the disease in this country.

NewsDramatic reduction in prescribing of hepatitis C antivirals may leave many curable patients untreated
A new study analyzed a large national prescription database to estimate hepatitis C treatment courses over time and trends by patient and prescriber characteristics from 2013–2025. Prescriptions rose rapidly after direct-acting antivirals first became available, peaking in 2015, but then declined sharply through 2025.

NewsSimple antiseptic can reduce newborn infections
A new Cochrane review finds that chlorhexidine likely cuts umbilical cord infection rates by about 29% in low- and middle-income countries, and may reduce newborn deaths.

NewsScientists combine algae and oyster shells for biodiesel born in the bayou
Researchers have developed an inexpensive way to make biodiesel from materials found along the banks of their Louisiana bayou: algae and oyster shells.
-
NewsScreening and preventive treatment program reduced tuberculosis incidence 83% among Tibetan children living in northern India
A study shows that significant reduction of tuberculosis (TB) transmission and burden (the total impact of health problems on a population) among schoolchildren in high-burden areas can be achieved using existing TB screening, treatment and follow-up protocols.

NewsCancer drug repurposed to treat drug-resistant herpes
Researchers have successfully repurposed an FDA-approved cancer drug, doxorubicin, to treat drug-resistant strains of herpes. A digital tool that combs through chemical compounds and flags those that may be effective against herpes infections, identified doxorubicin, a known anticancer drug.

NewsBiosensor detects early fungal outbreaks, advances plant biotechnology
A new biosensor detects the emerging presence of fungus on plants at the molecular level, paving the way for next-generation crop protection and the development of stress-tolerant plants.
-
NewsMapping the hidden gene highways of wastewater biofilms
A new study uncovers the hidden microbial connections within wastewater biofilms by combining Hi-C sequencing with multi-omics to directly map which phages and plasmids are associated with which microbial hosts.
-
NewsField-portable assays help scientists study and explore caves
A new study shows that field-portable assays are effective at identifying microbes directly in the field in real time, making it easier to study and explore caves. The researchers established a roadmap for thoroughly studying cave life, emphasizing the need to sample widely and from different materials.

NewsFluorescent imaging reveals how a global parasite develops, opening new paths for drug treatment
Researchers adapted a fluorescent imaging system typically used to study human cells, enabling real-time observation the parasite’s growth, a promising breakthrough against an organism that that infects both humans and animals.
