Pharma giant Merck apparently paid publisher Elsevier to put out a fake peer-reviewed journal. Well, okay. So, one little case of fraud. These things happen, right? Yes. They do. It turns out that these thigns have happened more than once - six times, in fact. Who is going to trust Elsevier now? I'm not inclined to. But what's worse is how this incident can be used by quacks who don't want to believe real peer reviewed science.
