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

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

In 1977, Woese and Fox proposed the Archaea as a new domain of life and that the tree of life is divided into three branches — the Eukarya, Bacteria and Archaea. Although a three-domain tree was ...

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 ...

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 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 ...

Single-celled archaea microbes pack their DNA into flexible coils that expand and stretch much like a Slinky does. This kind of molecular gymnastics had never been seen before in other organisms and ...

Archaea and bacteria are two different domains of cellular life. They are both prokaryotes, as they are unicellular and lack a nucleus. They also look similar (even under a microscope). However, DNA ...
