NewsClove oil yields new Pickering emulsion formulation with enhanced antibacterial properties
Researchers developed a sustainable Pickering emulsion using carbon quantum dots (CQDs), promising solid particles for food applications, derived from clove essential oil residue. They found that CQDs with 40% ethanol demonstrated the highest emulsifying efficacy.

NewsMulti-dose vaccines administered in the same site boost immune response
New research suggests that receiving multiple doses of a vaccine in the same limb leads to faster antibody development, an important strategy for providing immunity as quickly as possible during a pandemic or disease outbreak.

NewsIntranasal herpes infection may produce neurobehavioral symptoms, study finds
A new study finds that herpes infection through the nose can lead to anxiety, motor impairment and cognitive issues. The research is the first to show that, by exploiting a cellular enzyme, the virus can produce behavioral symptoms.

NewsCircadian rhythms in tea plant microbiomes shed light on nutrient cycling
A groundbreaking study has uncovered a fascinating connection between the circadian rhythms of tea plants and the microbial communities in their rhizosphere, providing new insights into nutrient cycling.

NewsStudy discovers tuberculosis genes necessary for airborne transmission
Tuberculosis bacteria rely on a family of genes that help them survive the challenging journey from one person’s lungs to another person’s during coughing, sneezing or talking, according to a study that offers new targets for tuberculosis therapies.

NewsResearchers pinpoint shared stress response network between long diverged algae and plants
A research team has compared algae and plants that span 600 million years of independent evolution and pinpointed a shared stress response network using advanced bioinformatic methods.

NewsMicrobiome: Researchers improve bacterial analysis for clinical applications
Different extraction methods can obtain the DNA of certain bacterial species differently, which can significantly distort the determined microbiome composition. Scientists have developed a computer-based method for correcting extraction bias.

NewsPrevalence of neutralizing antibodies to AAV2 and AAV9 in individuals with Niemann-Pick disease
A new study shows that more than half of individuals with Niemann-Pick disease, type C1 (NPC1) who were tested lacked neutralizing antibodies against either adeno-associated virus (AAV) 2 or AAV9.

NewsInhaled COVID vaccine study begins recruitment for phase-2 human trials
Researchers have started a phase-2 clinical trial on a next-generation, inhaled COVID-19 vaccine. Findings from the phase-1 trial indicate that the vaccine is more effective at inducing immune responses than traditional injected vaccines are.

NewsGenes combined with immune response to Epstein-Barr virus increase MS risk
In multiple sclerosis (MS), antibodies to the common Epstein-Barr virus can accidentally attack a protein in the brain and spinal cord. New research shows that the combination of certain viral antibodies and genetic risk factors can be linked to a greatly increased risk of MS.

NewsFA Bio licenses two microbes to IFF’s Crop Biologicals division to advance microbial solutions for crop health
FA Bio, a leader in the discovery of sustainable agricultural products, has extended a license agreement on two microbials to IFF’s Crop Biologicals business.

NewsGreat whale pee funnel carries nutrients thousands of miles, boosting phytoplanktons
A new study shows that whales carry huge quantities of nutrients horizontally, across whole ocean basins, from rich, cold waters where they feed to warm shores near the equator where they mate and give birth.

NewsBacteria and minerals work together to detoxify arsenic in contaminated soils
New research shows that the interaction between arsenic-oxidizing bacteria and goethite, a common Fe mineral, significantly accelerates the conversion of arsenic from its highly toxic form, arsenite [As(III)], into the less harmful arsenate [As(V)].

NewsPurified immunoglobulin F(ab′) 2 prevents lethal staphylococcal enterotoxin B intoxication in mice and rhesus monkeys
Purified F(ab′)2 fragments are an effective antidote to lethal SEB doses in mice and rhesus monkeys, and therefore might be a favorable candidate for treating patients with severe SEB intoxication, a new study suggests.

NewsScientists develop low-cost handheld sensor test for airborne bird flu
Researchers have developed a prototype sensor that detects a virus that causes bird flu (H5N1) in air samples. The low-cost handheld sensor detects the virus at levels below an infectious dose and could lead to rapid aerosol testing for airborne avian influenza.

NewsTranscription factor PoMbp1 promotes the growth of Pleurotus ostreatus by regulating polysaccharide utilisation
A study investigating the growth and development of Pleurotus ostreatus has found that PoMbp1 contains an APSES domain and localizes to the nucleus, indicating it belongs to the fungal-specific APSES transcription factors family.

NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewssiRNA-AGO2 complex inhibits bacterial gene translation: a novel therapeutic strategy for superbug infection
Scientists have demonstrated that exosomes can serve as delivery vehicles to introduce AGO2-loaded siRNA into the cytoplasm of bacteria, and in turn down-regulated gene expression of the mRNA that shares sequence complementarity to the siRNA.

NewsScietnists probe Rhytismataceae on twigs of Rhododendron
Following a study of fungal specimens collected from the twigs of Rhododendron species in China, three new genera were proposed and 21 species residing in 11 genera of Rhytismataceae were delimited, which include 18 new species and three new combinations.
