NewsHIV infections would increase by 10% average if CDC funding for HIV testing ends, study predicts
Researchers used a computer model to quantify the effect of funding cuts for HIV testing. They estimate that HIV infections could increase an average of 10% in 18 U.S. states if this funding is interrupted or ended.

NewsBacteria incorporate forever chemicals into cell membrane molecules
New research shows that bacteria incorporate polyfluoroalkyl carboxylates—a type of Per- and Polyfluoroalkyl Substances (PFASs)—into the molecules that make up their cell membranes.

NewsInuit recommendations to address high rates of tuberculosis in Nunavik, Quebec
Tuberculosis rates for Inuit living in Nunavik, the Inuit lands in northern Quebec, are 1,000 times greater than among non-foreign-born Quebeckers, and underresourcing of local health care adds to hardship from the disease, found new research.

NewsA new mouse model of virus-driven liver cancer may open the door to better diagnosis and treatments
Researchers have created the first mouse model in which chronic viral infection progresses to liver cancer, closely mirroring what happens in people with hepatitis C.

NewsNovel treatment protocol targets the deadliest cases of C. difficile infection
A new study demonstrated that fecal microbiota transplantation (FMT) can rapidly reverse systemic inflammation and improve survival in patients with fulminant Clostridioides difficile infection.

NewsA world within the leaves: Sign up for our fascinating free webinar
A single tree can harbour hundreds of species - yet few people will realise that some of those species live within the very leaves themselves. A fascinating free webinar will explore the fascinating world of fungal communities that live inside leaves.

NewsHigh‑fat diets linked to rapid decline in protective gut immune cells
In a preclinical study, researchers found that even short-term exposure to high levels of dietary fat results in a quick and selective loss of critical gut immune cells called ILC3s, promoting intestinal permeability and inflammation.

NewsVanderbilt Center for Antibody Therapeutics signs agreement to develop anti-measles antibody treatment
The Vanderbilt Center for Antibody Therapeutics has signed an option agreement with Saravir Biopharma Inc. for the company to develop human monoclonal antibodies isolated in the laboratory of James Crowe Jr., MD, for the treatment and prevention of measles.

NewsMillions-of-years-old insect symbioses are surprisingly fragile
An introduced bacterium displaces the sawtoothed grain beetle’s symbiotic partner, leading to the complete collapse of a previously stable symbiosis within a few generations.

NewsOregano, rosemary and ‘time’: Long-term swine study shows natural-compound benefits
In a rare long-term public study that compared the effects of phytochemicals from rosemary and oregano with antibiotic growth promoters, animal scientists found that the natural agents given to weaned pigs supported favorable gut health and growth performance later in their lives.

NewsScientists warn antibacterial soaps and wipes can fuel antimicrobial resistance
An international team of scientists is warning that everyday antibacterial soaps, wipes, sprays, and other “germ‑killing” products are quietly contributing to the global rise of antimicrobial resistance (AMR) while providing no added health benefit for most consumer uses.

NewsCommon virus plus mono associated with increased risk of MS
Having the disease infectious mononucleosis, often called mono, caused by the Epstein-Barr virus is associated with an increased risk of developing multiple sclerosis (MS), according to a study.

NewsClimate change may produce ‘fast-food’ phytoplankton
Scientists report that as sea surface temperatures rise over the next century, phytoplankton in polar regions will adapt to be less rich in proteins, heavier in carbohydrates, and lower in nutrients overall.

NewsThe tumor microbiota: A new frontier in cancer biology
A new study synthesizes evidence from different types of tumors, particularly those characterized by low microbial biomass, where conclusions require particularly rigorous validation. By outlining a roadmap of experimental and analytical standards, this work provides the basis for more robust research.

NewsScientists develop therapeutic, nasally delivered DNA vaccine for tuberculosis
Research shows the vaccine — in combination with drug therapy — accelerated a relapse-free TB cure in mice, improved activity of a drug-resistant TB regimen and stimulated immune responses in nonhuman primates.

NewsUnexpected potential bacterial symbiosis found in fungus that causes angular leaf spot
Scientists have uncovered an unexpected microbial relationship that could help explain differences in the severity of a major disease affecting common beans. The discovery sheds light on how the pathogen evolves and may point to new strategies.

NewsMissing gut bacteria may prevent some people with celiac disease from fully benefiting from high-fiber supplements or diets
Many people with celiac disease are advised to eat more fibre to support digestion and manage symptoms, either through diet or prescribed fibre supplements. New research shows that the benefits of that fibre may depend on whether the right bacteria are present in the gut to break it down.
