NewsNew insights into phage–bacteria interactions in the gut microbiome
Researchers studied the interactions between bacteria and phages within the gut microbiome and highlighted the significance of the phage community to shape the microbiome that contributes to host health and diseases.

NewsDesigning self-destructing bacteria to make effective tuberculosis vaccines
Preclinical studies have demonstrated a more effective tuberculosis (TB) vaccine through engineering bacteria to self-destruct and swiftly stops the infection on cue, which activates a more robust immune response.

NewsScientists build robot to track plant-fungal trade networks, revealing nature’s underground supply chains
New research uses advanced robotics to track the hyper-efficient supply chains formed between plants and mycorrhizal fungi as they trade carbon and nutrients across the complex, living networks that help regulate the Earth’s atmosphere and ecosystems.

NewsBacteria consumed by immune cells become part of the cell
Immune cells that eat bacteria in the body don’t stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells alive, according to a new study.

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.

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.

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.

NewsHeat-stressed reefs may benefit from coral-dwelling crabs
A species of branching coral is able to recover from heat stress and wounds due to its mutualistic relationship with crabs in the Great Barrier Reef Corals, a new study shows. This evolutionary partnership will inspire coral reef restoration strategies in the future.

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.

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.

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.

NewsStealth virus: Zika virus builds tunnels to covertly infect cells of the placenta
Researchers have discovered that Zika virus in the placenta builds underground tunnels, a series of tiny tubes called tunneling nanotubes, that facilitate the transfer of viral particles to neighboring uninfected cells.
