NewsStalled microbiomes: cystic fibrosis disrupts early gut development in infants
A new study highlights key differences in the gut microbiome (communities of bacteria) of infants with cystic fibrosis (CF) compared to that of healthy infants, and how these alterations may adversely affect their health.
-
NewsResearchers shed light on the mechanisms of bacterial flagellar motors
Researchers have determined the structure and mechanisms of the key components in the flagellar motor, which bacteria use to turn their flagella and move.

NewsDangerous bacteria lurk in hospital sink drains, despite rigorous cleaning
Even in modern hospitals, drains can serve as reservoirs for known and novel pathogens, according to a new study.

NewsProtein shuttling mechanism helps bacteria pump out antibiotics
By a joint-university effort, the mechanism of a bacterial efflux pump complex to remove molecules, including antibiotics, has been determined and the extent of bacterial toxin resistance by the complex has also been evaluated with a cutting-edge device.

NewsBacteria evolved to help neighboring cells after death, new research reveals
A study has shown that a type of E coli bacteria produces an enzyme which breaks the contents of their cells down into nutrients after death. The dead bacteria are therefore offering a banquet of nutrients to the cells that were their neighbours when they were living.

NewsBacterial cellulose promotes plant tissue regeneration
Researchers have successfully uncovered the molecular mechanisms by which bacterial cellulose patches stimulate the regeneration of plant wounds, offering potential applications in grafting, pruning, and ornamental flower cutting for enhanced plant healing.

NewsDiabetes can drive the evolution of antibiotic resistance, study reveals
A new study shows that people with diabetes are more likely to develop antibiotic-resistant strains of Staph. The results show how the diabetic microbial environment produces resistant mutations, while hinting at ways antibiotic resistance can be combatted in this patient population.

NewsNew study sheds light on the causes of fevers of unknown origin in sub-Saharan Africa
By conducting a retrospective observational study, the causes of fevers of unknown origin (FUO) in sub-Saharan Africa were investigated using conventional diagnostic methods, highlighting the appropriate needs of point-of-care testing in the regions.

NewsOutokumpu’s bedrock reveals a smelly surprise
In a borehole in Finland, volatile organic compounds (VOC) are detected in the bedrock and groundwater due to the presence of a highly diverse underground microbial community, which reflects the composition of VOC and thus the bedrock characteristics.

NewsLong-term yogurt consumption tied to decreased incidence of certain types of colorectal cancer
A new study finds that yogurt consumption over time may protect against colorectal cancer through changes in the gut microbiome. Long-term consumption of two or more servings per week of yogurt was tied to lower rates of proximal colorectal cancer positive for Bifidobacterium.

NewsAfter sexual intercourse, both partners leave traces of their own unique genital microbiome
Researchers have shown that bacterial species are transferred between both individuals during sexual intercourse, and these species can be traced to a sexual partner’s unique genital microbiome, with potential for identifying perpetrators of sexual assault.

NewsCold temperatures promote spread of a bird pink eye pathogen at winter feeders
A pathogen for bird pink eye remains viable on bird feeders in winter conditions much longer than in summer conditions without losing any of its severity, according to a study.
-
NewsResearchers engineer biological reaction crucibles to rapidly produce proteins
Biomedical engineers have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, such as antibiotics.

NewsGuarding our seafood: innovative strategies against Vibrio parahaemolyticus
Recent research presents a novel approach to managing the risks posed by Vibrio parahaemolyticus, a common yet hazardous foodborne pathogen in seafood, offering a comprehensive framework for monitoring and mitigating health risks.
-
NewsScientists isolate ultra small bacterium that parasitizes archaea
Researchers have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the strain PMX.108T as new species and genus of Minisyncoccus archaeiphilus.
-
NewsA realistic ‘micro-gut’ model reflects the relationship between gut microbes and human diseases
An innovative and more physiologically relevant 3D micro-gut model, known as Gut-Microbiome on a chip (GMoC), provides an in-depth understanding of the complex interactions between the microbial community within the gut microbiome and their impacts on human gut health.

NewsWhale poo contains iron that may have helped fertilize past oceans
A new study suggests that nutrients that whales excrete may provide a key fertilizer to marine ecosystems. Whale excrement contains significant amounts of iron and nontoxic forms of copper, another essential nutrient that in some forms can harm life.
