Science Daily: Scientists stunned as bacteria rewire DNA machinery to shape cells
A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift reveals how evolution can turn old biological tools into entirely new ...
Bacteria are enclosed by a rigid cell wall, which can vary widely in its composition, helping to distinguish between different species of bacteria. When exposed to a dye called a gram stain, gram positive bacteria trap the dye due to the structure of their walls, while gram negative bacteria release the dye readily, because their cell wall is thin.
All cells can be sorted into one of two groups: eukaryotes and prokaryotes. A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not. Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells.
Phys.org: AI-powered staining in microbiology: Researchers introduce virtual Gram staining of label-free bacteria
A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...
AI-powered staining in microbiology: Researchers introduce virtual Gram staining of label-free bacteria
Effective, accurate and quick ways to screen and sort microbes are in short supply. Most methods available now rely on additional labeling steps to sort bacteria, which are typically time-consuming ...
Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...
A protein determines the shape of bacteria. Bacteria come in a wide variety of shapes, which are important for their fitness in their respective ecological niches. However, despite intensive research, ...
