NewsGut microbiota and the gut–brain axis: Mechanisms and therapeutic hopes for brain diseases
A new study looks at the gut–brain axis (GBA), a sophisticated bidirectional communication network that integrates neural, immune, endocrine, and metabolic pathways to govern brain function and systemic homeostasis.

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.

NewsReplicating bacteria DNA relies on accordionlike folds to separate
A new study deepens our understanding of what bacterial cells use to separate their DNA during replication, since they do not rely on external structures like human cells do.

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.

NewsKorean live microbes survey finds less inflammation from consuming fermented foods
A new study that analyzed South Korean health data to determine whether live microbe intake from fermented foods like kimchi is associated with certain health indicators, found a link between increased consumption of live microbe-rich foods and lower systemic inflammation.

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.

NewsKimchi-derived probiotic found to promote binding and excretion of intestinal nanoplastics
Scientists have announced that a lactic acid bacterium isolated from kimchi can help promote the removal of nanoplastics from the body by binding to them in the intestine.

NewsWeaning, more than a change of food: It shapes a life-long, healthy gut
According to a team of researchers, weaning or switching from milk to solid food in early life doesn’t just change what babies eat, it helps reprogram the gut’s immune defenses to mount faster and stronger responses that can last into adulthood.

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.

NewsDiet determines the bacteria present in microbial gardens cultivated by ants
Researchers studying leafcutter ants have demonstrated how bacteria in the colonies respond to different diets provided by ants to the fungi they cultivate. The study paves the way for a better understanding of how colonies function and may lead to the discovery of new molecules for biotechnological use.

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.

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.

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.
-
NewsNew drug candidate extremely effective against H. pylori bacterium
Researchers have discovered that metronidazole targets two central protective proteins of Helicobacter pylori: an enzyme responsible for detoxifying harmful reactive oxygen species and a protein that repairs damaged proteins.
-
NewsScientists uncover how HPV-positive cancers hide from the immune system — and how to make them visible again
A new study solves a major mystery in cancer immunology by uncovering how HPV hides cancer cells from the immune system by using MARCHF8 to destroy MHC-I, which serves as a warning flag for the immune system.
-
NewsBiochar’s climate benefits may reverse over time in acidic soils, new study finds
A study reveals that biochar can both decrease and increase emissions of nitrous oxide, a potent greenhouse gas, depending on how long it has been in the soil. The findings highlight the importance of considering long-term impacts when evaluating climate solutions.

NewsA newly identified disease of corn and sorghum may be mistaken for iron deficiency
A newly identified bacterial disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem.
-
NewsLong-term biochar use reshapes soil carbon storage through microbial pathways
A new long-term study reveals that biochar, a carbon-rich material derived from crop residues, can significantly enhance soil carbon storage, but its effectiveness depends strongly on land use and soil type.

NewsFantastic fungi found with ability to freeze water
An international group of researchers has discovered the identity of fungal proteins that can catalyze ice formation at high subzero temperatures. One potential application of this discovery could be to engineer weather.
