By freezing a crucial phosphoric acid complex to near absolute zero, scientists uncovered a single, unexpectedly stable structure at the heart of proton transport.

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 ...

Artificial intelligence (AI) is transforming how scientists understand proteins—these are working molecules that drive nearly every process in the human body, from cell growth and immune defense to ...

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 ...

Learn how oxygen’s early rise could have given complex life the energy boost it needed to evolve.

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
