A researcher has retracted a paper from Diabetes after re-using some Western blots in one of the figures from other papers.
According to the retraction notice, the first and corresponding author — Eric Berglund, formerly at Vanderbilt University in Nashville, Tennessee — contacted the journal himself to report the error, for which he takes full responsibility.

John Ioannidis, a professor at Stanford University and one of the most highly cited researchers in the world, has come up with some startling figures about meta-analyses. His new paper, published today in Milbank Quarterly (accompanied by this commentary), suggests that the number of systematic reviews and meta-analyses in literature have each increased by more than 2500% since 1991. We asked Ioannidis — who is perhaps most well known for his 2005 paper “Why Most Published Research Findings Are False” (and was featured in a previous Retraction WatchQ&A article) — why such a massive boost these publication types in scholarly literature is potentially harmful.
Retraction Watch: You say that the numbers of systematic reviews and meta-analyses have reached “epidemic proportions,” and that there is currently a “massive production of unnecessary, misleading, and conflicted systematic reviews and meta-analyses.” Indeed, you note the number of each has risen more than 2500% since 1991, often with more than 20 meta-analyses on the same topic. Why the massive increase, and why is it a problem?Continue reading We have an epidemic of deeply flawed meta-analyses, says John Ioannidis
