NewsRice resists change: Study reveals viral tools for probing gene function fall short
Researchers tested two popular viral vectors - barley stripe mosaic virus (BSMV) and foxtail mosaic virus (FoMV) - to see if they could temporarily switch genes on or off in rice (Oryza sativa). They found no evidence that these virus-enabled reverse genetics (VERG) techniques work in rice.

NewsHuman ‘mini-noses’ help understand why RSV infections are more severe in children than in adults
Why does RSV affect babies more severely? To better understand the cellular reasons behind this age-related difference, researchers compared infant and adult human nose organoids, also called mini-noses, regarding their susceptibility and response to infection.

NewsReceptors in mammary glands make livestock and humans inviting hosts for avian flu
A new study shows that the mammary glands of several other production animals besides cows – including pigs, sheep, goats, beef cattle and alpacas – are biologically suitable to harbor avian influenza, due to high levels of sialic acids.

NewsNew review reveals how microbial communities accelerate the global spread of antibiotic resistance
A new scientific review has uncovered how complex microbial communities, including those in the human gut and the natural environment, act as powerful engines that drive the evolution and spread of antimicrobial resistance.

NewsIncreased risk of severe bacterial infection after high teenage BMI
High BMI and poor physical fitness during later adolescence increase the risk of both contracting and dying from sepsis and other severe bacterial infections in adulthood, according to a study.

NewsHow polyphenol-rich diets promote healthy aging through microbiome and metabolome modulation
New findings suggest that polyphenol-rich diets can serve as a simple, safe, and effective nutritional strategy to counteract inflammation and support healthy aging.

NewsEverolimus alleviates ulcerative colitis via inflammation suppression and microbiota remodeling
A new study reveals how targeting the CLEC4E receptor and reshaping the gut metabolite axis offers a promising therapeutic avenue for inflammatory bowel disease.

NewsHorseshoe crab fossil reveals early mass-burial event and ancient microbial attack
A remarkably preserved horseshoe crab fossil from North America offers rare insight into some of the earliest known cases of animal disease in a Late Carboniferous swamp – more than 300 million years before the age of dinosaurs.

NewsParasitic fungus may have emerged 18 million years before the ants with which it lives today
An analysis of 309 strains indicates that the genus Escovopsis emerged 56.9 million years ago, but only began interacting with today’s mutualistic ants 38 million years ago, challenging the theory that they all emerged at the same time.

NewsStudy suggests that chlorine treatment may impact the risk of legionnaires’ disease
Preliminary results of a nationwide study suggest that the disinfectant used to treat water before it is distributed through pipes may impact the incidence of Legionnaire’s disease in certain parts of the country.

NewsHow did Bronze Age plague spread? Ancient sheep might solve the mystery
Researchers have found the first evidence of a Bronze Age plague infection in a non-human host. The scientists discovered Y. pestis DNA in a 4,000-year-old domesticated sheep from Arkaim, a fortified settlement located in the Southern Ural Mountains of present-day Russia.

NewsInside the gut: What our poo could tell us about our diet, gut microbes and health
Researchers have found that molecules in stool samples can accurately reflect what people eat and how their gut microbiome responds, offering a potential new tool to study nutrition and its impact on health.

NewsStudy reveals how bacteria resist hostile attacks from rival bacteria
When attacked by bacteria from a different species, Pseudomonas rapidly assembles the type VI secretion system (T6SS) – to inject its aggressor with a toxic cocktail. A new study probes how Pseudomonas can strike back when it has already been hit by a deadly cocktail itself.

NewsStudy unlocks the key microbes contributing to postnatal growth retardation
Postnatal growth retardation (PGR) has a high incidence during early postnatal development of piglets and humans. Researchers have found that hindgut-enriched Methanobrevibacter smithii compromises the weight gain in the pig PGR model.

NewsYeast cell factory developed to convert methanol into L-lactate
Researchers developed a yeast cell factory to produce L-lactate from methanol as the sole carbon source, and evaluated the commercial potential and environmental impacts of this bioprocess.

NewsOld molecules show promise for fighting resistant strains of COVID-19 virus
SARS‑CoV‑2 continues to mutate, with some newer strains becoming less responsive to current antiviral treatments like Paxlovid. Now, researchers have identified several promising molecules that could lead to new medications capable of combating these resistant variants.

NewsNew study reveals how natural humic substances reshape soil carbon cycling and boost antibiotic resistance
Researchers have uncovered surprising links between natural humification processes in soil, carbon metabolism, and the spread of antibiotic resistance. Subtle shifts in the composition of humic substances can reshape microbial metabolism and alter the abundance of antibiotic resistance genes.

NewsNew study reveals that parasite-produced dopamine can alter host behaviour
A new study has shed light on how Toxoplasma gondii, the causative agent of toxoplasmosis, can alter host behaviour. The research findings show that such behavioural changes are achieved, at least in part, through dopamine manipulation caused by dopamine produced by the parasite itself.

NewsClimate extremes triggered rare coral disease and mass mortality on the Great Barrier Reef
Marine biologists have identified a devastating combination of coral bleaching and a rare necrotic wasting disease that wiped out large, long-lived corals on the Great Barrier Reef during the record 2024 marine heatwave.

NewsDose of psilocybin, dash of rabies point to treatment for depression
Researchers used a combination of psilocybin and the rabies virus to map how – and where – the psychedelic compound rewires the connections in the brain. Specifically, they showed psilocybin weakens the cortico-cortical feedback loops that can lock people into negative thinking.
