He suggested that these quantum effects might be playing a role in maintaining the genetic stability in living organisms. However, ther ...

Today, at the microbial mats in the Atacama Desert and other sites throughout the world, scientists are investigating what the earliest eukaryotic cells may have looked like, the partnerships they may ...

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 a ...

Unlike actin, tubulin proteins only appear in very few species of Asgard archaea.Eukaryotes are organisms whose cells contain a nucleus, such as plants and animals. The origin of microtubules had ...
