I'm studying Parkinson's disease for a project assigned in class. During my research, I came across two articles published three days apart, the former from a research group detailing one of their studies and the latter from the BBC. They discuss completely separate aspects of the disease and have nothing to do with each other, but the BBC article copies nearly word for word a section from the research article that lays out a basic description of the disease. It's been nearly seven months since the BBC article was published. Should I just ignore this possible case of plagiarism or should I send an email to the BBC? I don't imagine anything worthwhile will happen, except that the necessary citation might be added. It's probably not worth the effort, but I was hoping for some advice either way, because I can't make up my mind. Thanks.
