The Archaea was recognized as a third domain of life 40 years ago. Molecular evidence soon suggested that the Eukarya represented a sister group to the Archaea or that eukaryotes descended from ...

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 ...

Studies of the Archaea have had a substantial impact on the field of biology. Carl Woese carried out several pioneering studies, examining the evolution of the genetic code, the translation apparatus ...

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

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

The biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It ...

Archaea are the third domain of life, separate from the domains of bacteria and eukaryotes. While bacteria and archaea are both unicellular organisms that lack a nucleus, they are very different in ...

It turns out your skin is crawling with single-celled microorganisms -- and they're not just bacteria. A study has found that the skin microbiome also contains archaea, a type of extreme-loving ...

Scientists know relatively little about archaea compared to their bacterial counterparts, but evidence of their roles in health and disease are beginning to trickle in. Methanogens are not the only ...
