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 ...

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 ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

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 ...

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