How did life leap from simple microbial cells to the complex, structured cells that make up animals, plants, and fungi? A new ...

Study of Asgard archaea reveals insights into the evolution of cellular complexity through analysis of cytoskeletal proteins.

Connecting tubes between bacteria and a kind of microbe called archaea may reflect a symbiotic relationship that led to ...

Asgard Archaea: Are These Single-Celled Organisms Our Microbial Ancestors? “It’s undeniable at this point that Asgard archaea contributed a lot to the complexity that we see in eukaryotes ...

Archaea are microorganisms that were only discovered in the 1970s, and scientists still have a lot to learn about them. One challenge is that archaea are difficult to raise in the laboratory. As of ...

But evolution can also go in the other direction, leading to greater simplicity in the genome. This so-called genomic ...

Archaea, key players in the human microbiome, are linked to various diseases but their pathogenic potential remains speculative. This study highlights their role in conditions like periodontitis ...

How archaea compete with and defend themselves against bacteria has revealed new antibacterials that kill bacteria by targeting the peptidoglycan cell wall.

As bacteria become increasingly resistant to antibiotics and other antibacterials, there is a growing need for alternatives. In a study published in the open-access journal PLOS Biology, Tobias ...
