This recent Why Files from the Graduate School at the University of Wisconsin-Madison discusses a study published last fall in the journal Nature, which has since been denounced because of insufficient evidence. The site discusses some of the substance of the original article and some criticisms of it. It then moves into a more general discussion of the scientific method, conflicting data, and scientific bias. This Why Files provides an entertaining look at some recent and ongoing issues surrounding scientific research, but because it includes a lot of information in a brief publication, the report is probably more suitable for an informed audience.
