Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton ...

Around the same time, researchers James Watson and Francis Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used Franklin's ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

But filopodia can also wreak havoc: metastatic cancer cells use them to invade new regions of the body. Filopodia are composed of hexagonal bundles of proteins that give them structure and strength.

Scientists use RNA origami to fold biomolecules into nanotubes, forming cytoskeleton-like structures, advancing synthetic biology toward artificial cells.
