Deep-sea vent metals may have helped early cells run essential chemistry before they could survive on their own.

The work challenges the assumption that all life descended from one free-living cell. Instead, it suggests that two microbial ...

A recent study has proposed the existence of a common ancestor of bacteria and archaea. Here’s how the history of life splits ...

In the late 1970s, a new branch was added to the tree of life, and archaea joined bacteria and eukarya, as domain classifications. Archaea and bacteria are both simple forms of cells called ...

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 ...

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 ...

A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic ...

How life arose remains a looming question in science that researchers are seeking to answer by studying the features shared among life today. Everything alive is made up of cells, and what made the ...

Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows. In Antarctica is a small lake, called Deep Lake, that is so salty it remains ice-free all ...
