NewsQuiet emergence of superbug threat revealed in new study
Decades-old hospital samples have helped researchers uncover how a deadly antibiotic-resistant “superbug” quietly tightened its grip across the globe.

NewsResearchers propose new listeria labelling for smoked salmon and other ready-to-eat foods
Researchers are proposing a new labelling scheme designed to give consumers a better opportunity to choose ready-to-eat foods, such as smoked salmon and spiced pork roll, without risking infection with Listeria bacteria.

NewsNovel plasmid confers phosphorylation-driven streptomycin resistance in plant pathogen
The genetic basis underlying the unusually high-level streptomycin resistance observed in the field-derived strain TX-0702 of Clavibacter michiganensis has remined unknown until a new study identified a previously uncharacterized plasmid.

NewsBacteria can learn and form memories without a brain
Scientists have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments.

NewsBiologists uncover a molecular mechanism that helps bacteria spread antibiotic resistance genes
A new study reveals the molecular mechanism behind one of the most powerful mechanical actions in all of biology, the reeling in of tiny surface fibers called type IV pili.
-
NewsA non-toxic guard against Lyme disease could soon be an everyday purchase
Rather than vaccinating people or pets against Lyme disease, researchers are targeting the “reservoir hosts” — small mammals like squirrels, chipmunks and white-footed mice — that naturally carry the bacterium and pass it to ticks.

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.

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.
-
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.
-
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.

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.
-
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.
-
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.
-
NewsScientists deploy biofilm-targeting approach to improve crop disease resistance
A new study reports a biofilm-targeting approach for improving crop disease resistance. By replacing the native chloroplast transit peptide (CTP) of MOC1 with a secretory signal peptide (SP), the team redirected the enzyme from chloroplasts to the apoplast.
-
NewsCryo-EM helps identify the mechanisms of dental plaque formation
Researchers used cryo-electron microscopy to provide new insights into how Porphyromonas gingivalis causes plaque formation, revealing the 3D structure of Mfa pili, an arm-like filament which enables the bacteria to stick to host tissues and other microbes.
-
NewsA 'copper economy' helps fungi and bacteria build better biofilms
Scientists have discovered that two common human pathogens can work together by managing copper in their shared environment - a finding that could open new ways to break down stubborn mixed biofilms.

NewsProbiotic bacteria Lactobacillus rhamnosus alleviates diabetic nephropathy in rat models
A recent study demonstrates that the probiotic strain Lactobacillus rhamnosus exerts significant renoprotective effects rat models of diabetic nephropathy.
