I recently met somebody who read and believed the initial headlines for that story but never heard any updates. I think science reporting has some serious problems and no clear way to hold anybody accountable for it.
If there was a news site that purely had follow up to old stories, I'd subscribe. The media only provides it for things like trials that people continue paying attention to.
One reason people stall investigations is they know the press will forget after a few months.
In my case I knew of the aftermath because I work on the field and followed the reports of science writers such as Ed Yong and Carl Zimmer as well as the blog of Rosie Redfield, one of the microbiologists that took part in the testing and posterior refutation of the published results.
