Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

Over time, the nucleus and other compartments evolved – and the eukaryotic cell was born. “This remarkable cytoskeleton was probably at the beginning of this development. It could have enabled Asgard ...

Unlike prokaryotic cells, all eukaryotic cells have nuclei. Nuclei house most of a cell’s genetic information – much of it in the form of DNA – making a nucleus a sort of blueprint for building future ...

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

Daniel Mills, Ludwig-Maximilians-Universität München During this time, some of the defining characteristics of modern eukaryotic cells—the nucleus, mitochondria, cytoskeleton, cell membrane, and ...

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

Like other eukaryotic cells, neurons have a cytoskeleton that consists of three main polymers: microtubules (green), intermediate filaments (purple) and actin filaments (red). Microtubules emanate ...

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

The cytoplasm of eukaryotic cells is like chicken soup-it's chock full of organelles suspended like chunks of assorted vegetables and noodles in cytosolic broth. The broth also contains filaments of ...
