Sumos vs. Firemen. This happened.
We should always have doubts when the news media claims scientists have conclusive proof one way or another. In part, this is because science does not work that way. Each piece of research is a piece of a far larger puzzle. Often, what the press claim is a major discovery is in fact just a small step in a very long process.
It does not help, of course, that many reporters don't know the first thing about science and have a bad habit of appealing to authority, filing their copy and then heading off down the pub while the subs argue over commas. The problem is, the public don't read many academic journals so rely on scientifically illiterate or alliterate hacks to get their information.
