Vast Disembodied Brains From Space

Well, that may be a bit of an exaggeration, but I find the possibilities of this story fascinating. If DNA-like structures can indeed evolve and duplicate themselves in clouds of interstellar dust, who's to say that the process of evolution couldn't continue from there to actual intelligence of some kind? Of course, this whole thing is based on computer modeling – it's not as if they've actually found any of these things, just proven (they think) that such a thing could exist. It could bring a whole new meaning to the idea of dust bunnies, though, couldn't it?
