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 ...

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 ...

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how ...

Hyperthermophilic archaea are true survival experts. They thrive in boiling hot springs and deep-sea vents—environments lethal to nearly all other forms of life. Researchers at the German Archaea ...

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 ...
