Woot! Another step towards improving the human immune system. Something like this sounds oddly similar to something I said last October:
"It would be nice if one could program the current immune system with a broad range identifier would eliminate all but the rarest of virus infections. Then the next step would be to somehow analyze foreign invaders to give scientists advance warning. Then a way to create fixes automatically. David Weber gave a shot at imagining something like that but with alien tech implants and nanotech in his Troy series. Some DNA rewriting in the first book as well. How accurate he was I leave to you."
The 'way to create fixes automatically' part would fit in well with this article. Now they just need a detection method, a way to communicate to the human host, and something to link it all together. Whee!
