NewsNew study suggests RNA present on surfaces of leaves may shape microbial communities
Biologists have shown that the surfaces of plant leaves are coated with a diverse array of RNA molecules, suggersting this may play a role in shaping the microbial communities that inhabit them, potentially influencing plant health and interactions within their environment.

NewsMediterranean diet changes gut bacteria, boosting memory and cognition
A new study suggests the Mediterranean diet’s brain-boosting benefits may work by changing the balance of bacteria in the gut.

NewsThese bacteria perform a trick that could keep plants healthy
Researchers have shown that some types of soil bacteria can influence a plant’s balance of growth and defense. The bacteria produce an enzyme that can lower a plant’s immune activity and allow its roots to grow longer than they would otherwise.

NewsStudy uncovers how a new gut microbe drives the gut-lung axis
New findings highlight how a little-known member of the gut microbiome reshapes the lung immune environment to have both beneficial and detrimental effects on respiratory health.

NewsSeasonal flu vaccine study reveals host genetics’ role in vaccine response
Scientists have found that influenza subtype-bias is primarily driven by host genetics, particularly major histocompatibility complex (MHC) class-II polymorphisms, with prior exposure playing a secondary role.

NewsPotentially harmful bacteria slip through antimicrobial showerheads
Researchers report that antimicrobial silver-containing showerheads are no ’silver bullet’. In real-world showering conditions, most microbes aren’t exposed to the silver long enough to be killed.
-
NewsThe surprising role of gut infection in Alzheimer’s disease
A new study implicates link between a common virus and the disease, which travels from the gut to the brain and may be a target for antiviral treatments.
