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

PROTEUS, a system designed to harness “directed evolution,” can speed the process up by years, or even decades.

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

A decade ago, the existence of Asgard archaea was unknown. However, in 2015, researchers analyzing deep-sea sediments uncovered gene fragments that suggested the presence of a new, previously ...

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

New Clues On Eukaryote Evolution From Asgard Archaea Like bacteria, archaea are single-celled organisms. However, there are significant differences, especially regarding their cell envelopes and ...

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).

It's been hypothesized that the fusion of sperm and egg cells goes back to an ancient cell that could perform a kind of genetic exchange. A new study has suggested that the process of sexual ...

Archaea Inhabit Our Microbiome, but What Are They Doing There? Scientists know relatively little about archaea compared to their bacterial counterparts, but evidence of their roles in health and ...

Archaea—one of the three primary domains of life alongside bacteria and eukaryotes—are often overlooked and sometimes mistaken for bacteria due to their single-celled nature and lack of a ...

Like bacteria, archaea are single-celled organisms. However, there are significant differences, especially regarding their cell envelopes and metabolic processes.
