They've survived for billions of years in boiling acid, deep-sea vents and salt flats. Now, some of Earth's oldest life forms—microbes called Archaea—are offering a new weapon in the fight against one ...

Just call them archaea (ar-kee-uh) - archaebacteria are no more. Archaea were once considered to be quite similar to bacteria, but these prokaryotes are just weird enough to be classified in their own ...

Beyond bacteria, fungi and archaea are emerging as powerful regulators of digestion, immunity, and disease risk, revealing ...

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

A parasite that not only feeds off its host, but also makes the host change its own metabolism and thus biology: NIOZ microbiologists Su Ding and Joshua Hamm, Nicole Bale, Jaap Damsté and Anja Spang ...

Scientists describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation. In a ...

Thanks to microscopy, early biologists were able to make a binary distinction: there were eukaryotes and bacteria. The former had large, complex cells with internal compartments, while the latter were ...

In an article published in the journal Emerging Infectious Diseases, the authors discussed the involvement of archaea, a lesser-known but important component of the human microbiome, in various ...

Editor's Note: This article was originally published at ScienceNordic. Two meters down, among the dark sediments at the bottom of the Bay of Aarhus in Denmark, scientists have discovered a crucial ...

Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and ...

Eukaryotes drastically differ from archaea and bacteria (collectively, prokaryotes) by the complex organization of eukaryotic cells. The signature features of this organizational complexity include ...

The alternative text for this image may have been generated using AI. Besides noting the uncertainty in numbers, one must also acknowledge that the definition of biofilms has been changing and ...
