NewsInstitutions team up to advance first AI-designed mRNA vaccine against deadly tick-borne disease
Scientists are developing what could become the world’s first mRNA vaccine against severe fever with thrombocytopenia syndrome (SFTS)—a tick-borne viral disease associated with this condition.

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.

NewsCARB-X to support investigation of Exhalon’s breath-based lower respiratory tract infection testing platform
CARB-X has awarded Exhalon US$1M in seed funding to evaluate whether exhaled breath can be used as a non-invasive sample type to aid in the rapid and accurate diagnosis of lower-respiratory tract infections (LRTIs).

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.

NewsTuberculosis: Scientists develop novel drug candidate for combating resistant pathogens
Researchers have developed a promising new substance for targeting bacteria that cause tuberculosis. The team have produced a compound that inhibits the pathogens’ ability to produce energy and causes them to die.

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.
