Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...
Bernander and Lindås provide an overview of recent studies that have enhanced our understanding of the archaeal cell cycle. They discuss the multiple-origin mode of DNA replication, the archaeal ...

Live Science on MSNDefense system common to all life came from 'Asgard'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 ...
In fact, Asgard archaea appeared almost heaven-sent for research: they turned out to be a missing link between archaea and eukaryotes – that is, between archaea and organisms whose cells contain ...
Instead, in their view, there are just two: bacteria and archaea. All organisms with complex cells, from a Paramecium to us, are just a branch of archaea. Introducing Asgard.
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 are single-cell life forms without a nucleus. She also studied which molecular mechanisms are involved in the transmission of signals from the archaea's environment to its motility structure.
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 ...
