NewsGenetic switch controlling microbiota impact could help control leaf growth in poor soils
A new study has identified a genetic circuit in plants that controls individual leaf growth and allows the plants to adapt to their environment. The findings could help the development of more drought-resistant crops.

NewsStudy probes light-harvesting proteins of purple sulfur bacteria in high-salt, high-alkaline environments
Halorhodospira halophila, a purple sulfur bacterium, is believed to perform photosynthesis efficiently by integrating light harvesting protein complexes LH2 and LH1-RC. Researchers employed cryo-electron microscopy to investigate.

NewsSuperbugs in our food: a new hope for tackling drug resistance
Researchers highlight the potential of quorum sensing inhibitors (QSIs) as a novel approach to tackle Pseudomonas aeruginosa. The study explores the mechanisms of action of various QSIs and potential applications in food safety and healthcare.

NewsStudy reveals how bacteria in microbiome medicine trigger tumor-killing cells
Microbiotica has presented new data on the mechanism of action of MB097, a clinical-stage drug candidate being developed as a co-therapy in combination with KEYTRUDA® (pembrolizumab) in patients with advanced melanoma.

NewsFungi more vulnerable than bacteria in degrading alpine ecosystems
A new study provides the first evidence that alpine pioneer community degradation led to declines of 27% in fungal richness, 8% in bacterial richness and about 50% of endemic microorganisms.

NewsBeacon Technology Solutions, Illinois Tech awarded grant to advance far-UVC disinfection research
Beacon Technology Solutions, with collaborators at Illinois Institute of Technology, has been awarded a grant to support a novel study on how Far-UVC technology can help mitigate the spread of infectious diseases in public spaces.

NewsNeutrophil-to-lymphocyte ratio and its correlation with tuberculosis infection
A new study reveals a significant negative correlation between neutrophil-to-lymphocyte ratio (NLR) and the risk of tuberculosis infection (TBI), particularly in males and individuals with hypertension.

NewsLung abnormalities seen in children and teens with long COVID
An advanced type of MRI uncovers significant lung abnormalities in children and adolescents with long COVID, according to a new study. PREFUL MRI doesn’t require the use of radiation or intravenous contrast agents and can be done while the patient breathes freely.

NewsUnexpected species-specific patterns in study of giraffe gut flora
The gut bacteria of giraffes are not primarily determined by what they eat, but by the species they belong to., according to a new study analysing the link between diet and gut flora in three giraffe species in Kenya. The study also provides new knowledge that can help secure the food supply of endangered giraffe species.

NewsHerpesviruses may contribute to Alzheimer’s disease via transposable elements
Researchers have outlined the pathway human herpes simplex virus-1 (HSV1) can use to contribute to Alzheimer’s disease in aging brains, and also share two FDA-approved, commercially available drugs that reverse this pathway in a laboratory setting.

NewsNew paper-based device boosts HIV test accuracy from dried blood samples
Scientists have trialled a more precise medical device to measure HIV viral loads by engineering a paper device with wax-printed patterns that create precise channels and collection spots, ensuring it consistently collects the same volume of blood.

NewsAs dengue spreads, researchers discover a clue to fighting the virus
Children who experience multiple cases of dengue virus develop an army of dengue-fighting T cells, according to a new study. Most children who experienced two or more dengue infections showed very minor symptoms—or no symptoms at all—when they caught the virus again.

NewsNew study calls for ethical framework to protect Indigenous genetic privacy in wastewater monitoring
Researchers have called for new ethical frameworks to protect Indigenous communities’ genetic privacy in the growing field of wastewater surveillance. The study examines how analysis of community wastewater raises significant privacy concerns for Indigenous populations.

NewsLaser-powered device tested on Earth could help us detect microbial fossils on Mars
Scientists hoping to identify fossil evidence of ancient Martian microbial life have now found a way to test their hypothesis, proving they can detect the fossils of microbes in gypsum samples that are a close analogy to sulfate rocks on Mars.

NewsStromatolite study provides new detail on the impact of volcanic activity on early marine life
Analysis of fossilised rocks known as stromatolites - layered rock formations created by ancient microorganisms, such as bacteria - from more than two-and-a-half billion years ago has provided new insights into the conditions on Earth before the evolution of oxygen.

NewsLactobacillus-dominated uterus significantly boosts pregnancy outcomes
Researchers analyzed recent studies on the reproductive microbiome and its effects on fertility. They found that a Lactobacillus-dominated (LD) uterine environment significantly improves pregnancy outcomes. Similarly, pregnancy success rates were higher in LD environments.

NewsBackyard poultry face HPAI risk when migrating mallards stop to rest
Knowing where, when and for how long mallard ducks – natural carriers of avian influenza – stop and rest as they migrate can help predict the probability that they will spread bird flu to backyard poultry flocks, according to a new study.

NewsResearch suggests common viral infection worsens deadly condition among premature babies
Researchers say they found that infection with a common virus that can be transmitted from mother to fetus before birth significantly worsens an often-fatal complication of premature birth called necrotizing enterocolitis (NEC) in experiments with mice.

NewsStudy uncovers porcine reproductive and respiratory syndrome virus’s impact on swine immunity
Scientists used single-cell RNA analysis to reveal key immune mechanisms in lungs of swine infected with PRRSV. They found higher numbers of protective anti-inflammatory M2-like macrophages (SPP1-CXCL14high) were observed in less virulent infections, suggesting a potential role in promoting lung healing.

NewsScientists invent new drug candidates to treat antibiotic-resistant bacteria
Researchers designed a new family of antibiotics that’s a variation of an existing drug called vancomycin, which is used as a last resort for extremely ill patients. The new version of vancomycin targets, bonds to and renders inactive two different parts of a molecule on the surfaces of pathogenic bacteria.
