This is one reason that many, many times on HN when there is a link to a blog post about some news story on a science discovery, I post the link to Peter Norvig's article on how to evaluate research,

as it seems to be that most readers need more practice in critical reading of statements about science. PZ is one of the few bloggers who knows most of those points already, but he frequently writes about other people who forget them, so here in this thread too I'll remind HN readers about Norvig's advice on how to read about science.
