NewsChemolithoautotrophic breakthrough: bacteria converts CO2 into p-coumaric acid without light
p-Coumaric acid is a critical building block for pharmaceuticals, cosmetics, and functional foods. A new study research leverages C. necator H16’s ability to use H2 as an energy source and CO2 as its sole carbon source.

NewsMXene-based hydrogel disrupts bacterial biofilms and reprograms immune cell metabolism to reverse bone resorption in periodontitis
Periodontitis treatment not only requires effectively disrupting bacterial biofilms but also reshaping the local immune metabolic microenvironment to fundamentally break the vicious cycle of “infection-inflammation-bone resorption.”

NewsHow do vaccine conspiracy beliefs develop?
Researchers analyzed five years of longitudinal panel survey data collected between 2020 and 2024 and examined how vaccine-related conspiracy beliefs were associated with media skepticism during the COVID-19 pandemic.

NewsLemurs fall prey to human herpes virus
A new study marks the first time researchers have been able to confirm human herpesvirus in lemurs via a molecular analysis, outlining the cases of four privately owned animals who died from the illness.

NewsBiofortified millet benefits toddlers without supplement side effects
Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes.

NewsFirst immune pathway discovered that stops a normally harmless fungus spreading through the body and causing deadly disease
An immune pathway has been discovered which prevents a normally harmless fungus developing into a fatal infection.

NewsSoil properties determine how farmland microbes release nitrous oxide
A study of agricultural soils reports that physicochemical constraints and microbial functional differences jointly regulate denitrification, causing carbon and nitrogen inputs to alter N₂O and N₂ production differently among soil types.

NewsDo human noroviruses also switch their shape?
Researchers investigating whether human norovirus undergoes conformational changes in response to environmental condition successfully produced virus-like particles (VLPs) of the human norovirus GII.3 strain and determined their structures.

NewsHidden genome variation steers growth in fungus-dependent orchid
A chromosome-level genome and population survey of the fungus-dependent orchid Gastrodia elata has revealed how hidden genetic differences may shape growth, tuber form, and carbohydrate allocation.

NewsWarming reshapes how nitrogen is stored and lost in flooded rice soils
A three-year field experiment shows that higher temperatures accelerate nitrogen cycling while promoting retention in protected soil pools.

NewsSilencing a fungal wall protein cuts powdery mildew on melon leaves
Powdery mildew fungi survive on living plants behind a cell wall that provides both structural support and a shield against host immunity. Researchers have now identified the fungal cell wall assembly protein ECM33 as a weak point in that defense.
-
NewsIntratumoral Fusobacterium as a prognostic and predictive biomarker in resectable colorectal cancer
Research supports the use of Fusobacterium as a prognostic and predictive biomarker in patients with resectable stage I–III CRC. Its presence was associated with more aggressive disease, a weaker immune response, and limited benefit from adjuvant chemotherapy.

NewsOxygen nanobubbles turn biochar into an active defense against cadmium in flooded rice soils
A newly engineered biochar maintained oxygen around rice roots, shifted cadmium into more stable soil forms, and substantially reduced cadmium accumulation in rice plants.

NewsFree webinar: The secret world of the vaginal microbiome
A fascinating free webinar will shine a light into the secret world of the human microbiome and how it influences gynecological health. It will focus on what the vaginal microbiome can reveal about health, disease, and the gaps in care we still need to address.

NewsPet dog microbiota may protect young children from respiratory tract infections
Children who have been in contact with dogs in early childhood are on average healthier and require fewer antibiotic courses than children without such contact. The protective association is explained, at least in part, by the spread of dog-associated microbes in the home.

NewsAmazonian ‘zombie’ fungus harbors a hidden stage inside forest mosses, new study reveals
Researchers have found evidence that the “zombie-ant” fungus, globally known for controlling ant behavior and forcing infected ants to bite onto plants before dying, also lives hidden inside mosses in the Amazon rainforest.

NewsAncient smallpox genomes reveal how European colonisation brought the disease to the Americas
Researchers have recovered and analysed the first ancient smallpox virus genomes ever identified in the Americas, providing the strongest direct evidence to date that the disease was introduced through European colonisation.

NewsEvolutionary history may help explain why some people develop more severe COVID-19 than others
A study suggests that some of the genes involved in the body’s immune response today bear the marks of ancient battles with infectious diseases. It also identified rare genetic variants that may help explain why some people developed more severe COVID-19 than others.

NewsDecoding the gut microbiome’s symphony in health and disease
Researchers have reported effective strategies for simultaneously measuring thousands of microbial and host proteins. They systematically compared five state-of-the-art mass spectrometry approaches using human fecal samples.

NewsHow does a deadly chicken virus escape vaccines designed to slow it?
A new genome-wide study of the Marek’s disease virus identified 10 regions in the genome associated with what makes certain strains more virulent, and could inform next-generation vaccines.
