Drugs that rely on tiny strands of RNA to shut down the production of problem proteins have generated intense research interest in recent years. But they have to overcome a common difficulty: It's hard to get the RNA into target cells. Research presented at the meeting suggests there may be a straightforward solution: Pack the strands together to form nano-sized particles. And a second study indicated that a different kind of nanoparticle may lead to novel kinds of vaccines. Nanomedicine may be about to get a big boost.
