Scientists trace an ancient microbe, Asgard archaea, that gave rise to humans, animals, and plants more than 2 billion years ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

Researchers investigate into the various lineages of Asgard archae, and determine one related to Hods as the ancestor of ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes.

A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth’s most abundant land-based creatures that oxidize ammonia, according to an international ...

Following the drive to understand and control bacteria, it’s becoming clear that our methods have changed the very organisms we aim to understand, increasing resistance to tried-and-true antimicrobial ...

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 ...

AIST researchers, in collaboration with JAMSTEC, Hokkaido University and Tohoku University, have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the strain ...

Earth’s first life forms eventually took one of three different paths, forming the domains of Eukarya, Bacteria, and Archaea. These domains have been evolving separately for billions of years. Recent ...

Let’s say you’ve discovered a new bacterium or archaea and want to give it a name so that it can be classified and placed on the appropriate branch of the tree of life. According to the International ...
