Deep in hydrothermal vents beneath the Arctic Ocean, scientists have discovered an organism that sheds fresh light on the evolutionary link between simple and complex cellular life. The microbe and ...

Last month, many microbiologists were surprised to find that the familiar names and nomenclature for the bacteria and archaea they study had been rewritten, seemingly overnight. On December 10, the ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

A nucleus is one of many membrane-bound compartments that distinguishes our eukaryotic cells from the prokaryotic cells of microorganisms like bacteria. Eukaryotic cells also possess energy-producing ...

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, providing insights into its DNA recognition and cleavage mechanisms. The ...

Norman Pace has a problem with prokaryotes. It’s not that Pace has anything against the organisms themselves. The microbiologist and RNA scientist from the University of Colorado at Boulder has made a ...
