The tiny pantheon known as the Asgard archaea bear traits that hint at how plants, animals and fungi emerged on Earth.

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 ...

An artist’s depiction of an Asgard archaeon, based on cryo-electron tomography data: the cell body and appendages feature thread-like skeletal structures, similar to those found in complex cells with ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein ...

Researchers have profiled the molecular structure and features of a key part of the deadly Nipah virus. Experiments in cells showe how changes in the viral polymerase -- a protein involved in viral ...

Researchers think a microbe that was engulfed by an algal cell 100 million years ago has since evolved into an integral part of the cell's machinery. When you purchase through links on our site, we ...
