News Lack of dietary iron may impair immune cells’ ability to fight influenza
New research suggests that a lack of dietary iron can negatively affect the ability of immune cells to respond to viral infection in the lungs. In mice with dietary iron deficiency and influenza, immune cells struggled to produce a key signal needed to fight viruses and did not regain this ability.

NewsNobel Prize-awarded material that punctures and kills bacteria
Bacteria that multiply on surfaces are a major headache in healthcare. Researchers have found a new weapon to fight these hotbeds of bacterial growth – metal-organic frameworks. These materials can physically impale, puncture and kill bacteria before they have time to attach to the surface.

NewsBird flu viruses are resistant to fever, making them a major threat to humans
Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body’s ways of stopping viruses in their tracks, according to new research.

NewsMicroplastics disrupt gut microbiome and fermentation in farm animals
Microplastics, tiny plastic particles pervasive in agricultural environments, interact with and disrupt the microbial ecosystem in the rumen – the first stomach chamber of cattle, reveals an international study.

NewsMetabolites produced in the intestine play a central role in controlling obesity and diabetes
A study has identified a group of metabolites that travel from the intestine to the liver and then to the heart, where they are pumped throughout the body. These metabolites play an important role in controlling metabolic pathways in the liver and insulin sensitivity.

NewsAcid rain may be training soil bacteria to become more deadly
Acid rain from fossil fuel pollution may be quietly training soil bacteria to become longer-lived, more transmissible, and more deadly, according to a new study that tracks how a notorious foodborne pathogen rapidly evolved under simulated acid deposition.

NewsCuring hepatitis C can rebalance immunity in Indonesians living with HIV
A new study provides the first longitudinal immunological data on HIV/HCV-coinfected individuals in Southeast Asia, underscoring the importance of early hepatitis C treatment to prevent long-term immune and liver complications.

NewsMichigan cherry farmers find a surprising food safety ally: falcons
By shooing cherry-pecking birds away, kestrels also keep them from contaminating crops with their droppings, a new study shows. Kestrels were associated with a 3-fold reduction in droppings spotted on branches.

NewsFestive cheer: Soaked raisins ferment to turn water into wine
Scientists have discovered that soaking sun-dried raisins in water is a successful method of creating wine. It was thought that ancient wine production relied on the natural fermentation process of storing crushed grapes in jars, but Saccharomyces cerevisiae rarely colonizes grape skins.
