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.

NewsNew study reveals spleen-to-lung neutrophil axis orchestrates antiviral defense
Single-cell spatial mapping uncovers the spleen as a critical reservoir for lung neutrophils during respiratory viral infection, according to a new study.

NewsPromising active substance against hepatitis E identified
A drug that is already in clinical trials against hepatitis C virus can also prevent hepatitis E virus from replicating An international research team has filtered bemnifosbuvir, a nucleotide/nucleoside analogue, out of a library of active substances.

NewsBiochar particle size found to shape disease control in crops
Researchers have discovered that the particle size of biochar determines how effectively and how long it can suppress soil-borne pathogens, offering new insights for sustainable agriculture.

NewsWhole-genome sequencing is a powerful tool that can pick up on genetic signatures for antimicrobial resistance in UTIs: research
New research to be presented at MLSFF26 reveals whole-genome sequencing as a powerful tool that can distinguish between antibiotic-resistant and susceptible strains of urinary tract pathogens by identifying the specific genetic signatures that confer resistance.

NewsNeanderthals may have used birch tar for its anti-bacterial properties
Scientists extracted tar from modern birch tree bark, specifically targeting species known from Neanderthal sites. When exposed to different strains of bacteria, all tar samples were found to be effective at hindering the growth of Staphylococcus bacteria known to cause wound infections.

NewsDigital early warning systems essential as old diseases like cholera resurge in global crisis zones
A new critical analysis examines how the convergence of climate change, economic collapse, and conflict is bringing back a preventable disease once thought to be under control.

NewsFrequent infections in nursery help toddlers build up immune systems
Young children who attend nursery get sick more often than those who don’t, but they will go on to have fewer illnesses during early school years, finds a new review of evidence by a group of parent-scientists.

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.

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.

NewsScientists discover a bacterium that protects against long Covid
Scientists have discovered the key role played by a bacterium, Dolosigranulum pigrum, that is naturally present in the respiratory microbiome. When present in greater numbers, these bacteria are associated with a reduction in the persistence of symptoms characteristic of long Covid.

NewsInappropriate antibiotic use for COVID-19 is linked to resistance
Taking azithromycin for as little as one day triggers antibiotic resistance in the respiratory tract, according to a first-of-its kind look by scientists at the changes that occur in the microbiome of hospitalized patients who were treated for COVID-19.

NewsStudy maps how tuberculosis bacteria power themselves
A new study provides the first detailed 3D structure of a protein called EtfD, which the bacterium Mycobacterium tuberculosis uses to extract energy from lipids (fats), along with the first laboratory test capable of directly measuring its activity.

NewsLemongrass essential oil may target bacteria even more effectively than conventional antibiotics, research suggests
Lemongrass essential oil can be even more effective than traditional antibiotics against some Streptococcus bacteria under certain conditions, new research to be presented at MLSFF26 has found.

NewsWhat factors influence likelihood and severity of Ebola outbreaks?
Two new papers looked at factors that contribute to how Ebola outbreaks begin and how severe they become. This Q&A looks at how the results could inform public health interventions to prevent pathogen emergence or slow the spread of Ebola and other infectious diseases.

NewsSurface treatment of wood may keep harmful bacteria at bay
A recent study suggests that bacteria thrive more readily on untreated than treated wood surfaces. The finding has implications for hygiene in both homes and public spaces.
