It takes a lot of work to clean up the scientific literature, and some researchers and organizations deserve special recognition. That’s why we’ve established a “doing the right thing” category when we see praise-worthy progress in individual retractions, and have now gone a step further: We’ve created the DiRT Award, a new annual prize to […]

Researchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer. All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong. Since the corrections appear relatively extensive, we asked the journal if retractions were ever […]
