When different archaeal species mate, their CRISPR systems interact in ways that may influence their evolution.

Scientists estimate that subterranean organisms constitute a massive amount of carbon, 245 to 385 times greater than that contained in all humans.

What we can know about biology before the last universal common ancestor is limited—and we should be circumspect in filling in the gaps.

The ancient organisms appear to be more closely related to eukaryotes than previously appreciated.

We should take comfort in the fact that life on Earth had such unassuming, shared beginnings.

Meet some of the people featured in the June 2018 issue of The Scientist.

The discovery of copious new archaeal species is shedding light on the tree of life and revealing some unique cellular biology.

Identification of new archaea species elucidates the domain’s unique  biology and sheds light on its relationship to eukaryotes.

The paper describing the gene-editing method is retracted.
