Concerns attached to three more papers by retraction-laden management researcher

Fred Walumbwa, a management researcher with eight seven retractions, has received three expressions of concern from two journals after he failed to provide raw data following an investigation into potential errors. In the past, Walumbwa has said he only keeps data until his papers are published, but a lack of raw data has become a common theme in his notices, which … Continue reading Concerns attached to three more papers by retraction-laden management researcher

Voinnet’s notice count grows, as he notches his 18th correction

Olivier Voinnet, a high-profile plant scientist at ETH Zurich, has earned a mega-correction. It wrapped up a rough year for the biologist, which included his seventh retraction, and a CNRS investigation that found evidence of misconduct. This latest correction, to a paper on the mechanisms behind RNA silencing in Arabidopsis, was published in RNA. The 2007 paper has been cited … Continue reading Voinnet’s notice count grows, as he notches his 18th correction

Cropped, spliced image leads to a PLOS One correction

A PLOS One paper on morphine treatment for cancer cells has a couple issues with figures, prompting a massive correction — what we affectionately call a “mega-correction” — by the journal. In one figure, there was “an undisclosed splice.” Another figure contained two panels that were “mistakenly from the same sample.” The 2013 paper in question, … Continue reading Cropped, spliced image leads to a PLOS One correction

Animal welfare breach prompts Nature correction

A 2011 letter to Nature from Harvard researchers received its second correction today, this time after discovering the researchers conducted experiments in which mice may have “experienced more pain and suffering than originally allowed for.” That quote comes from an accompanying editorial in the journal, a rare move for a correction to a 2011 letter. … Continue reading Animal welfare breach prompts Nature correction

When should a paper be retracted? A tale from the obesity literature

In our line of work, we see it all — mega-corrections that don’t quite rise to the level of retraction, letters to the editor that point out seemingly fatal flaws in papers that remain untouched, and studies retracted for what seem like minor reasons. It can make you wonder what makes a paper worthy of … Continue reading When should a paper be retracted? A tale from the obesity literature
