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

Our skin and mucous membranes protect us like vigilant sentinels against the onslaught of harmful pathogens. This extraordinary defense owes its strength to epithelial cells—specialized tissues woven ...

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

Cells can also send out packages called exosomes, lipid vesicles that bubble off from the cell membrane. But for about 20 ...

A previously unknown protein in a family of bacteria found in soil and the human gut microbiome has been discovered—which ...

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.

To further investigate the cell contribution to the ICM, the researchers labeled DNA and actin and, starting at the eight-cell stage, tracked cellular positions after division using live cell imaging.
