NewsActinobacteria TFDB: a new comprehensive resource for transcription factor research in actinobacteria
Actinobacteria are a major source of bioactive natural products and exhibit an unusually high transcription factor (TF) abundance. A new study reports the development of Actinobacteria Transcription Factor Database integrating 629 TFs from 25 representative species.

NewsCommon probiotic ingredient turns immune cells into tumor killers
A probiotic bacterium secretes mannose—that significantly suppresses melanoma growth in mice by activating the body’s own immune defenses. Mannose enters CD8⁺ T cells through glucose transporters and inhibits a key protein called YAP1, which normally restrains T-cell killing power.

NewsGut microbiome: The hidden architect of liver cancer immunotherapy response
A comprehensive review synthesizes current advances linking gut bacteria to immunotherapy outcomes in hepatocellular carcinoma (HCC), the most common type of primary liver cancer.

NewsBillions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A comprehensive review brings together global evidence to strengthen public trust and counter misinformation as mRNA vaccines expand to prevent and treat more diseases.

NewsMicrobe–fertilizer pair cuts greenhouse soil emissions
A new study shows that inoculating organic fertilizers with denitrifying bacterium, especially when paired with mushroom residue organic manure, reduces N₂O emissions by reshaping the soil microbiome.

NewsBiochar helps paddy soils lock away carbon by reshaping microbial life underground
A new study reveals that straw and biochar both increase soil organic carbon, but biochar stores carbon more efficiently by guiding soil microbes toward stable carbon formation.

NewsDeep-sea extremophile yields protein that forms super stable biofilm
Scientists have discovered a protein secreted by a deep-sea extremophile — an organism adapted to extreme environmental conditions — that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.

NewsBiomarkers may someday help clinicians better detect Borrelia burgdorferi infections
Current tests for Lyme disease often miss infections during the early critical window and cannot tell whether bacteria are still present or were cleared years ago. New research suggests that anti-lipid antibodies may address these shortcomings.

NewsWidespread saprotrophs identified as the hidden engine of soil carbon decomposition
A nationwide study across China reveals that broad geographic distribution, rather than local diversity alone, determines which soil fungi actively fuel carbon decomposition and shape future carbon dynamics under climate change.

NewsEmissions from plankton help in forming cloud seeds over the world’s oceans
For nearly fifty years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment has suggested that it may be more important than previously thought.

NewsTick-borne diseases reported every month of the year and in every Illinois county
A new analysis of state health department data reveals that more than 6,400 Illinois residents were diagnosed with tickborne diseases from 2004-2022.

NewsScientists probe how proteins are inserted into cell membranes
Researchers looking at the cell membrane investigate how the proteins manufactured by the ribosomes in the cell interior reach their position within the membrane in the correct form and when the processes became established over the course of evolution.

NewsRice-crayfish farming strengthens soil nutrient cycling
Using metagenomic sequencing, a study has shown that integrated rice-crayfish systems increase the abundance of functional genes involved in methane oxidation, nitrogen degradation, denitrification, organic phosphorus mineralization, and phosphorus transport compared with rice monoculture.

NewsAntibiotics reverse damage caused to blood stem cells by chronic Salmonella
A new study has revealed that long-term Salmonella infections severely damage blood stem cells - but this damage is completely reversible. Giving an effective course of antibiotics fully restores the stem cells, allowing them to recover their health and rebuilding power.

NewsBack in action: Researchers make drug-resistant bacteria vulnerable again
New findings show that disabling a single bacterial protein can restore vancomycin’s power against resistant bacteria – and point to a new strategy for overcoming antibiotic resistance.

NewsViruses under stress: how viral shells change shape as they dry out
New research explores the structural dynamics and conformational changes of bacteriophage MS2 capsids under conditions of dehydration.
-
NewsSoil moisture tips the balance of nitrogen cycling
A new study reveals that nitrite accumulation is not simply a chemical outcome, but the result of mismatched microbial activities between ammonia oxidizers and nitrite oxidizers.

NewsCorals show climate change is reshaping the rules of survival
Which species benefit from climate change, and which are coming under pressure? Using corals as an example, researchers demonstrated that even seemingly successful life strategies can lose their advantage when environmental conditions change.

NewsIntestinal cells found to starve Salmonella of essential nutrients, revealing new tactic in infection defense
A new discovery sheds light on how the human body controls Salmonella infections and opens pathways for potential treatments for Salmonella and other food-borne infections.

NewsScientists uncover the hidden air risks in university cafeterias
By assessing two university cafeterias, a new study has shown that both sites had elevated temperature and PM10 levels, while one also showed high carbon dioxide and the other high total bacterial counts.
