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.

NewsGene swapping helped build the planet’s decomposers
Researchers have reconstructed the deep history of osmotrophic specialization in eukaryotes. Their findings suggest that four groups of eukaryotes which have specialized in osmotrophy first arose between 720 million and 1 billion years ago and that they share a toolkit of genes involved in osmotrophic functions.

NewsExtreme adaptation helps Dead Sea single-celled organisms to swim
Researchers have described in detail a structural adaptation supporting one of the Dead Sea’s few hardy inhabitants — a single-celled archaea called Haloarcula marismortui (H. marismortui). They characterized the proteins that form the archaeal filament, a long tail-like structure essential for movement.

NewsNew machine-learning models capture the rapid evolution of antimicrobial resistance
A tool developed to study bacterial evolution over billions of years has been successfully adapted to quickly and reliably identify resistant strains of Staphylococcus aureus.
-
NewsBacteriophage characterization provides platform for rational design
Researchers have described the bacteriophage Bas63 in unprecedented detail, supporting new mechanistic understanding of how these viruses function.

NewsFungi set the stage for life on land hundreds of millions of years earlier than thought
New research indicates the diversification of fungi hundreds of millions of years before the emergence of land plants. It suggests a common ancestor of living fungi dating to roughly 1.4–0.9 billion years ago.

NewsMolecular clock analysis shows bacteria used oxygen long before widespread photosynthesis
Researchers have constructed a detailed timeline for bacterial evolution and oxygen adaptation. Their findings suggest some bacteria could use trace oxygen long before evolving the ability to produce it through photosynthesis.

NewsTiny heroes and innovative technology can fight back against antibiotic-resistant biofilms
Researchers show that antibiotic-infused silver nanoparticles can effectively break down biofilms and also unveil a new sensing method to assess antimicrobial activity.
-
NewsSynthetic droplets cause a stir in the primordial soup
A synthetic droplet may give researchers clues on how the simplest forms of life on the planet could navigate their surroundings.

NewsResearch on bee virus origins uncovers buzz-worthy breakthrough
A study of deformed wing virus, a key driver in declines among European honey bee populations, show that one of the most common strains, DWV-A, originated in Asia and not Europe, as previously suggested.

NewsInhaling ethanol may treat respiratory infections
Inhaling low concentrations of ethanol vapour can disable the influenza A virus in mice, without harmful side effects, says a new study by scientists at the Okinawa Institute of Science and Technology (OIST). The scientists believe it may also treat similar viruses such as the one that causes Covid-19. ...
