Evolving Genome

Nature has a news article about a paper in their latest issue. The paper is from the ENCODE consortium and is attempting to map functional elements of the genome. The problem is that their assumptions didn't prove true. Functional elements weren't necessarily conserved and conserved regions weren't necessarily functional. There are a number of possible reasons for this that the news article gets into. I expect that this paper will be discussed for quite a while, so it's probably worth a read.
