Ancient enzymes function like nanopistons to unwind RNA

Molecular biologists at The University of Texas at Austin have solved one of the mysteries of how double-stranded RNA is remodeled inside cells in both their normal and disease states. The discovery may have implications ...

Lab one step closer to understanding how life started on Earth

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue—an enzyme known as an RNA polymerase—that provides new insights about the origins of life. ...
