NewsScientists uncover phylogeny and species diversity of fungal family Thaxterogaster
A new study utilizes five-locus data from 112 species to propose a relatively complete phylogenetic framework for the genus Thaxterogaster.

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.

NewsFungus ‘hacks’ natural immune system causing neurodegeneration in fruit flies
A fungus, called Beauveria bassiana, is found to manipulate the innate immunity of the fruit flies to attack their own brain cells, causing the penetration into the blood-brain barriers and eventually neurodegeneration.

NewsMpox: a better understanding of tecovirimat resistance
Through biochemical and structural studies, researchers managed to find out how the mutation of an enzyme could affect the interactions between it and the antiviral drug against mpox virus, tecovirimat, hence leading to a better understanding in developing new therapeutic approach against all mpox strains.

NewsSymbiotic bacteria ride along with marine cells in ocean’s upper layer
Symbiotic bacteria often accompany single-celled protists in the ocean’s upper layer. Some of these symbionts, scientists have discovered, are close relatives of bacteria pathogenic to animals, including humans.

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.

NewsReemergence of dengue serotype 3 may increase severity of outbreaks of the disease in Brazil
From the genomic and epidemiological surveillance of the circulating dengue virus strains, a more severe dengue epidemic may occur in Brazil, due to the re-establishment of dengue virus serotype 3 (DENV-3) and persists alongside with the serotype 1 and 2 (DENV-1 and DENV-2).

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.

NewsBiosensing platform simultaneously detects vitamin C and SARS-CoV-2
A portable and sensitive biosensing device has been developed by engineering researchers to detect both SAR-CoV-2 and vitamin C simultaneously, to monitor and boost health for the general public.
-
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.

NewsMicrobiome as a potential key to better treatment: Clinical study on new therapy for Crohn’s disease
A joint research project has found that a combination of dietary therapy and fecal microbiome transfer (FMT) greatly alleviate intestinal inflammation in mice. A clinical trial on this new therapeutic approach is under way to potentially treat Crohn’s disease.

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.

NewsSmart bioprospecting needed to expand the search for climate-friendly microalgae
New research has highlighted microalgae’s capacity as a solution in the fight against climate change, but researchers warn that “smart microalgal bioprospecting” is needed to unlock its full potential.
