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 nucleus. Yet ...

In the late 1970s, a new branch was added to the tree of life, and archaea joined bacteria and eukarya, as domain classifications. Archaea and bacteria are both simple forms of cells called ...

N-Glycosylation is a vital post‐translational modification in archaea that involves the attachment of oligosaccharide chains to specific asparagine residues on target proteins. This process not only ...

Deep-sea waters are warming due to heat waves and climate change, and it could spell trouble for the oceans' delicate chemical and biological balance. However, a study published in Proceedings of the ...

The archaea constitute a distinct domain of life yet several important aspects of their biochemical processes are closely related to those in eukaryotes. Archaea have therefore been used as a model ...

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 ...

Life is not possible without nitrogen. There are many ways for organisms to acquire nitrogen. For example, humans eat proteins for their high nitrogen content. Most microorganisms take up nitrogen ...

Scientists at UC Berkeley have discovered a microbe that bends one of biology’s most sacred rules. Instead of treating a specific three-letter DNA code as a clear “stop” signal, this methane-producing ...

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 ...

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.
