Scientists describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation. In a ...

Four billion years ago, Earth was violent, hot, and unstable. Yet new research suggests that by then, life had already reached a surprising level of complexity. At that time lived the last universal ...

In the late 1970’s, our understanding of the tree of life was fundamentally changed with the discovery and recognition of Archaea, a third domain of life along with Bacteria and Eukarya. While ...

The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers. The study, led by molecular ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in ...

Scientists have found further evidence to support the idea that the primary two domains of life, the Archaea and Bacteria, are separated by a long phylogenetic tree branch and therefore distantly ...
