Tiny relatives of our cellular ancestors reshape long protrusions within minutes and pull themselves across surfaces using ancient actin machinery.

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

Single-celled organisms called archaea occupy their own branch on the tree of life, like bacteria, but we know a lot less about them. Like bacteria, archaea also don't have a nucleus, and have ...

In the late 1970s, a new branch was added to the tree of life, and archaea joined bacteria and eukarya, as domain classifications. Archaea and bacteria are both simple forms of cells called ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

Single-celled archaea microbes pack their DNA into flexible coils that expand and stretch much like a Slinky does. This kind of molecular gymnastics had never been seen before in other organisms and ...

All multicellular organisms harbor an unimaginably large number of microorganisms in and on their bodies. The microbiome, i.e. the totality of these microbes, forms a functional, symbiotic unit with ...
