I used to get upset about these things, but nowadays if a writeup of a paper bothers me or sounds weird, i just go to the original publication. This might be hard if you're not at a university or otherwise have access to the journals. In this case i don't see anything particularly wrong. Just reading the abstract would tell you enough (linked from the article): http://www.pnas.org/content/early/2013/09/25/1313473110 http://www.pnas.org/content/early/2013/09/25/1313473110 The paper reports that the 28S RNA is split and that the ribosomes seem to be better at avoiding mistakes whilst keeping the same translation speed, and the authors speculate if these two things could be linked. And that's the gist from the Nat. Geo. article, too.
