NewsImmunity against seasonal H1N1 flu reduces bird flu severity in ferrets, study suggests
Pre-existing immunity against seasonal H1N1 flu might help explain why most reported human cases of H5N1 bird flu in the U.S. have not resulted in lethal outcomes, suggests a new study.

NewsNew insights into how specific gut cells respond to bacterial toxins
Researchers have characterized a specific gut cell type, BEST4/CA7+ cells, with the ability to interact with immune cytokine interferon-γ (IFNγ), and its regulation in cellular electrolyte and water balance, in response to bacterial toxins.
-
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.
