PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.
The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”
PubPeer commenters suggest this may not be enough, calling seven additional figures into question. Continue reading PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal
Former University of Tokyo researcher
Shigeaki Kato continues to put big numbers on the board.
Last month, we reported on his 26th, 27th, and 28th retractions, all in
Nature Cell Biology and cited close to 700 times. Yesterday, EMBO Journal and EMBO Reports published a total of five more retractions for the endocrinology researcher, who resigned from the university in 2012 following investigations found he had faked images.

Rakesh Kumar, a researcher with six recent corrections and one retraction, has had one of those corrections upgraded to a retraction.

The Japanese endocrinology researcher
Shigeaki Kato, with at least 25 retractions to his name, is alleged to have been the ringleader of a scheme to cover up other research misconduct at the University of Tokyo, his former employer, which investigated the activity.

We have an update on the complicated story of Milena Penkowa and Bente Klarlund Pedersen.
Two papers coauthored by the pair — who have both been
found guilty of scientific dishonesty by the Danish Committees on Scientific Dishonesty — have been retracted by the FASEB Journal.
Here’s one notice (both are unfortunately
behind a paywall): Continue reading Penkowa-Pedersen paper retracted nearly three years after being subjected to Notice of Concern

As a reporter on the police beat many years ago, one of us (Adam) used to hang out with a press officer whose desk at the station had the following sign: “Uma boca fechado não recolhe nenhum pé.”
At least, that’s what it would have been had we been in Rio. In Palmer Park, Maryland, the sign read: “A Closed Mouth Gathers No Foot.”
A group of Brazilian researchers has retracted their 2009 article on gut bacteria for plagiarism — but not before one of them decried such behavior as the nadir of scientific misconduct.
