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 ...

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 ...

When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research from ...

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 ...

A schematic tree of life with the primary domains, the Archaea and Bacteria shown in purple and blue, respectively and the secondary domain, Eukaryotes in green. The figure highlights key nodes in the ...

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

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

Defense systems found in all complex life on Earth came from "Asgard." The ancestor of plants, animals and fungi evolved around 2 billion years ago, likely from a group of complex microbes called ...

Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...
