New research sheds light on one of the biggest questions in biology: where did complex life come from? The answer may lie ...

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held ...

In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new ...

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

ETH researchers discovered related structures in Asgard archaea and describe their structure. These experiments show that ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.
