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 ...

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

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 ...

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 ...

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 ...

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 ...

Share on Pinterest New research sheds light on archaea — an important part of the human microbiome. Victor Torres/Stocksy The human microbiome includes bacteria, viruses, fungi, and archaea. Most ...

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 ...
