The emergence of eukaryotic cells is considered as a critical biological evolutionary event on Earth. The origin of eukaryotes and eukaryosis are frontier issues in both life and Earth sciences.

Earth’s immense web of life fill three broad domains—archaea, bacteria, and eukarya. Scientists from Monash University recently discovered hydrogen-producing enzymes in archaea, which were thought to ...

How do scientists study and classify life-forms? How can we understand the complex evolutionary connections between living organisms? Woese's breakthrough was momentous for at least three reasons.

A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials As bacteria become increasingly resistant to ...

Archaea are a major domain of prokaryotic microorganisms characterized by unique molecular and biochemical features distinguishing them from Bacteria and Eukarya. Their cell membranes typically ...

Every summer from 2013 to 2015, Dimitry Sorokin waded into the shallow, briny, alkaline lakes of Siberia’s Kulunda Steppe. Pale carbonate minerals crusted the pools’ edges, where lambs, too young to ...
