Breakthrough discovery blocks AIDS virus replicating

Spanish researchers, including scientists from the University of Valencia, have developed small synthetic molecules capable of joining to the genetic material of the AIDS virus and blocking its replication.

Was AEG Earth's first genetic material?

Before DNA became Earth's primary genetic material, early forms of life are believed to have used RNA to encode genetic instructions. But what was doing the job before RNA came on the scene?

Artificial DNA alternative evolves on its own

The prospect of artificial life has just come one step closer, with the discovery that a synthetic version of DNA and RNA can evolve like the real thing.

Engineers find new way to target cancer

For ten years, it's been known that RNA interference could potentially kill cancer by shutting off malfunctioning genes - but there's been no  efficient way to deliver the RNA.
