Interesting, thanks for the link. I wonder about their trial and error approach as well. Scientists have conveniently broken down genetic material into individual genes which are easy to think about, but biology doesn't care about being easy to think about. It seems like to get anywhere they would have to knock down genes in all sorts of different combinations, not just one at a time.
