Scientists are uncovering the surprising ways bacteria and archaea differ — and how these differences could be turned into weapons against dangerous infections. From bacteria’s peptidoglycan walls to ...

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 ...

In an article published in the journal Emerging Infectious Diseases, the authors discussed the involvement of archaea, a lesser-known but important component of the human microbiome, in various ...

Earth’s immense web of life fill three broad domains—archaea, bacteria, and eukarya. Scientists from Monash University recently discovered hydrogen-producing enzymes in archaea, which were thought to ...

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 ...

Two of our key defenses against viruses have persisted for billions of years, arising before complex life. A comparison of immune proteins called viperins from Asgard archaea (left) and from a group ...

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 ...
