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 ...

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 ...

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

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 ...

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, ...

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 ...

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 ...

Just call them archaea (ar-kee-uh) - archaebacteria are no more. Archaea were once considered to be quite similar to bacteria, but these prokaryotes are just weird enough to be classified in their own ...

Archaea are a relatively recently discovered group of microorganisms that occupy their own branch on the tree of life. Though similar in some ways to bacteria, they are not the same. Researchers have ...

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 ...

A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials As bacteria become increasingly resistant to ...

Led by Jizhong Zhou, Ph.D., the director of the Institute for Environmental Genomics at the University of Oklahoma, an international research team conducted a long term experiment that found that ...
