In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new ...

Defense systems found in all complex life, including the human body, came from primeval microbes known as 'Asgards.' ...

In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to ...

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...

Archaea are a distinct domain of life—along with bacteria and eukaryotes (i.e., organisms with a cell nucleus such as animals, plants and fungi).

Archaea research has fallen behind that of bacteria and eukaryotes by three decades, said Albers. She and other microbiologists are still trying to understand the basic cell biology of these microbes.

The Archaea evolved over 3 billion years ago but were only formally proposed as a domain 20 years ago. Today, many of the unique features and many of those that are shared with either the Bacteria ...

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 ...

Archaea that live in extreme environments like hot springs don’t really thrive on petri dishes in labs. “They’re very hard to culture. It’s super difficult,” says Raymann.

As the DNA unraveled, archaea’s key role in Earth’s history was becoming better understood. Archaea are extremely ancient organisms (their name in Greek is literally “ancient things”). Archaea have ...

Archaea, key players in the human microbiome, are linked to various diseases but their pathogenic potential remains speculative. This study highlights their role in conditions like periodontitis ...
