NewsAMR leads to more deaths and illnesses in the WHO African region than anywhere else
More than 1.05 million deaths were associated with antimicrobial resistance (AMR) and 250,000 deaths were attributable to AMR in the WHO African region, posing an unprecedented health threat.

NewsNew weapon against the super tough C diff bacteria shows promise
A researcher has demonstrated that a newer generation tetracycline antibiotic, Omadacycline, may be a promising tool in combating the resilient bacteria Clostridioides difficile (C diff), which causes an infection often picked up in hospitals.

NewsScientists devise bacterial toolkit for colonizing plants
Researchers have discovered a core set of genes required by commensal bacteria to colonize their plant hosts. The findings may have broad relevance for understanding how bacteria establish successful host–commensal relationships.

NewsGiant bacterium uses unique processes to power itself
Scientists have for the first time described the full genome of one species of the Epulopiscium family of giant bacteria, which they’ve named Epulopiscium viviparus.

NewsKeto diet protects against epileptic seizures by changing gut microbiome
Researchers have demonstrated that the changes the high-fat, low-carbohydrate ketogenic diet causes in the human gut microbiome can confer protection against seizures in mice.

NewsSingle-celled protists in the guts of animals thrive without the ‘powerhouse of the cell’
Almost all eukaryotic organisms, from plants and animals to fungi, can’t survive without mitochondria – the ’powerhouses of the cell’, which generate chemical energy using oxygen. Termites However, a new study by Lukáš Novák and Vladimír Hampl of Charles University, published in the journal PLOS Genetics, finds ...

NewsAlgae could replace animal-derived protein for building muscle
A new study demonstrates that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults.

NewsPhotodynamic action weakens resistance to antibiotics in bacteria that attack airways
A study of photodynamic inactivation (PDI) showed it has a novel capacity to modify bacterial sensitivity to antibiotics according to dosage, reducing the resistance and persistence of both standard and clinical strains.

NewsResearchers discover how to sabotage antibiotic-resistant ‘superbugs’
Scientists say they have learned how to sabotage a key piece of machinery that pathogens use to infect their host cells, and have developed a test to identify the next-generation drugs to target this vulnerable cellular machinery.

NewsB cell deficient patients gain protective T cell immunity after SARS-CoV-2 vaccination, infection
Researchers found that vaccinated B cell-deficient individuals had significantly reduced risk of moderate and severe disease in comparison to those who were not vaccinated, despite an absence of anti-spike antibody responses.
-
NewsScientists construct a synthetic yeast genome
The yeast genome contains redesigned chromosome sequences that can shed light on the impact of genetic variations on individual traits and potentially be used to reveal the causes of genetic diseases
