NewsA high-fat diet may impair response to infection
A new study in The Journal of Immunology reveals how a high-fat diet may impair the immune system’s ability to respond to infection by impacting the function of neutrophils, one of the first immune cells to respond to bacteria or viruses. The study demonstrated that male mice fed a high-fat ...

NewsNew model predicts how bacteria navigate obstacles to spread
A scientist has developed the first analytical model for predicting how bacteria spread in environments filled with obstacles. This model will help inform strategies for curbing bacterial infections or for designing better drug delivery.

NewsNature’s warriors: How rice plants detect and defend against viral invaders
A groundbreaking study uncovers a molecular mechanism by which rice cells perceive viral infections and initiate antiviral response, which significantly contributes to understanding of virus-host interactions for further disease resistance breeding.

NewsGatekeeping barriers manage communications between plants and bacteria
For over a century, the Casparian strip has been known as the root’s doorman, controlling what enters the plant. But a new study reveals it has a second job: regulating the delicate metabolic trade between plants and bacteria.

NewsUnknown microorganisms used marble and limestone as a habitat
Research work has revealed unusual structures that are probably due to the activity of an unknown microbiological life form. Unusually small burrows, i.e., tiny tubes that run through the rock in a parallel arrangement from top to bottom, were discovered in marble and limestone of the desert areas of Namibia, Oman, and Saudi Arabia.

NewsTeam finds regional, age-related trends in exposure to drug-resistant pathogen
A study from 10 US states found drug-resistant Campylobacter jejuni infections were highest in the 20-39 age group and that quinolone-resistant C. jejuni infections increased from 22.6% of those tested in 2013 to 33.54% in 2019. It identified regional differences in C. jejuni resistance to quinolones and six other classes of antibiotics.

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.
