NewsResearchers reveal m6A epigenetic modification controls arbovirus infection and transmission between vertebrates and mosquitoes
Researchers reveal that N6-methyladenosine (m6A) epigenetic modifications in mosquito-borne flaviviruses (MBFs) enhance viral propagation in vertebrates and thus increase transmission from vertebrates to mosquitoes.

NewsNovel biosensing platform enables fingertip blood-based micro-volume t-cell immune monitoring
A new platform, known as Tip Optofluidic Immunoassay Interferon-Gamma Release Assay (TOI-IGRA), could revolutionize how people monitor their immune health. The platform allows for the precise quantification of pathogen-specific T-cell responses using a mere 15-25 μL of fingertip blood.

NewsShifting from biotic to abiotic drivers of urban microbial multifunctionality under drought and rehydration
Scientists conducting microcosm experiments on Zoysia japonica, a common urban turfgrass, simulated four drought intensities and recovery by rehydration. They analyzed alteration in microbial communities and biochemical cycling to pinpoint the drivers of urban microbial multifunctionality.

News10 Years, 70% shift: Wastewater upgrades quietly transform river microbiomes
Researchers investigated how the upgrade of a WWTP influenced nitrogen-cycling microorganisms and DNA viruses in its receiving river. The research compared the river whose WWTP was upgraded during the study period against the river whose upgrade occurred prior to the study.

NewsPeriphyton closes the nitrogen budget gap in rice paddies
Scientists identify a previously overlooked microbial N sink in rice paddies. Periphyton, a thin microbial community that develops at the soil–water interface, is composed of algae, bacteria, and extracellular polymeric substances, forming a dense microhabitat with strong capacities for nutrient uptake, transformation, and temporary storage.

NewsFrom palm oil to designer enzymes: researchers reprogram yeast cells
Many everyday products contain fatty acids from palm oil or coconut oil, but the extraction of these raw materials is associated with massive environmental issues. Researchers have now developed a biotechnological approach that could enable a more environmentally friendly production method.

NewsNew study uncovers how rice viruses manipulate plant defenses to protect insect vectors
Rather than passively “hitchhiking” within insect vectors, rice viruses actively manipulate plant defense pathways to protect their insect carriers.

NewsFungal denitrification dominates soil N2O emissions after vegetation restoration in the Karst region
A new study demonstrates that soil fungal nirK-derived N2O in the karst region are significantly distinct between cropland and forest, soil NO3‒-N and sand are important drivers of the soil N2O emissions variation, especially after vegetation restoration.

NewsA ‘one-pot’ assay of or rapid portable identification of genotypes I and II African swine fever viruses
Researchers in search of an African swine fever virus genotyping method developed an isothermal ‘one-pot’ CRISPR-Cas12i3/Cas13d-based assay, designated OBServe.v2, to detect two amplified targets from multiplex recombinase polymerase amplification (RPA) in a single tube.

NewsResearchers identify mangrove tree stems as previously underestimated methane source offsetting blue carbon benefits
A new study reveals that mangrove tree stems represent a significant yet previously underestimated source of methane. Additionally, stem emissions showed a strong correlation with soil methane fluxes, indicating that methane produced by anaerobic microbial activity in mangrove soils is transported upward through specialized aerenchyma tissues within the trees.
