Like bacteria, archaea are single-celled organisms. Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and metabolic processes.

Tiny magnetic bacteria that live in tightly bound groups are showing scientists how life might have evolved complex, multicellular forms. These rare bacteria can’t survive alone – they depend on one ...

They're also incredibly old Bacteria consist of a single cell. They do not have bones and are not like big animals that leave ...

Single-celled organisms that group together can generate stronger water currents to pull in food, a benefit that may have encouraged early life forms to assemble into colonies, according to a new ...

Under microscopes, scientists found that giant single-cell organisms were able to vacuum up more food when they are stuck together. By Jack Tamisiea For a creature made up of only a single cell ...

derived from the Greek word for bacteria-eaters, or in shortened form, "phages." Scientists have sought to learn how the single-cell organisms survive phage infection in a bid to further ...
