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.

NewsWhy some people naturally control HIV even after stopping therapy — and how we can leverage that to treat others
New research offers a path toward life without daily HIV pills, suggesting a common diabetes pill could help achieve long-term remission.

NewsSmart wound dressing delivers antibiotics on-demand, accelerating healing and reducing resistance
Biomedical engineers have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound. The material could help rapidly clear wound infections to accelerate healing while reducing the unnecessary use of antibiotics.

NewsReplicating bacteria DNA relies on accordionlike folds to separate
A new study deepens our understanding of what bacterial cells use to separate their DNA during replication, since they do not rely on external structures like human cells do.

NewsKorean live microbes survey finds less inflammation from consuming fermented foods
A new study that analyzed South Korean health data to determine whether live microbe intake from fermented foods like kimchi is associated with certain health indicators, found a link between increased consumption of live microbe-rich foods and lower systemic inflammation.

NewsWeaning, more than a change of food: It shapes a life-long, healthy gut
According to a team of researchers, weaning or switching from milk to solid food in early life doesn’t just change what babies eat, it helps reprogram the gut’s immune defenses to mount faster and stronger responses that can last into adulthood.

NewsFood scientists develop new antimicrobial for cleaning and sanitizing dry-food processing equipment
New research describes a novel chemical mixture for sanitation in low-moisture environments. Scientists found that a formulation containing cyclomethicone combined with vinegar-based acetic acid was the most effective against Salmonella and Cronobacter bacteria.

NewsMulti-strain probiotic therapy shows promise in preventing bacterial vaginosis recurrence
A global team of experts has identified a promising new approach to prevent recurrence of bacterial vaginosis (BV). In a phase 1 randomized clinical trial, researchers found that a short course of a multi-strain probiotic restored protective bacteria to the vagina, significantly reducing disease recurrence.

NewsStudy shows breath test can confirm bacterial infection
A study shows how molecules that are only broken down by infecting bacteria, and not by gut bacteria, can be used to confirm infection. By enriching these molecules with a naturally occurring carbon isotope, the researchers found that carbon dioxide produced when they break down is easily detected in a breath test.

NewsTarget behind cancer drug shown to help fight influenza in mice
A protein already targeted by FDA-approved cancer drugs may also help the body fight influenza. A study found that Programmed Death-Ligand 1 (PD-L1), best known for helping tumors evade immune attack, instead helped immunocompromised mice clear flu-infected lung cells and survive infection.

NewsScientists uncover how HPV-positive cancers hide from the immune system — and how to make them visible again
A new study solves a major mystery in cancer immunology by uncovering how HPV hides cancer cells from the immune system by using MARCHF8 to destroy MHC-I, which serves as a warning flag for the immune system.

NewsPrototype breath tests spot bacterial infections in minutes
Researchers have adapted the long-used breath test for Helicobacter pylori, a bacterium that causes a common stomach infection, expanding the technology’s capabilities to detect a broader range of bacterial infections.
