Journal flags cancer paper from Karolinska researchers

A journal has issued an expression of concern (EOC) for a 2011 cancer paper, while Karolinska Institutet investigates “concerns” about some of the data. After the Journal of Cell Science (JCS) received a tip from a reader, it investigated, but was unable to resolve the concerns. So the journal asked KI–where all the authors work–to … Continue reading Journal flags cancer paper from Karolinska researchers

Journal won’t look at allegations about papers more than six years old, nor comment on those from “public websites”

After a paper is published, how long should a journal consider allegations of misconduct? For one journal, that answer is: Six years.

Authors retract two plant biology papers over duplicated images

Plant scientists have issued two retractions after noticing several images had been duplicated within and across the papers. The papers both appeared in March 2002 in The Plant Cell and The Plant Journal. The last author on both papers — Jonathan Jones, a professor and group leader at The Sainsbury Laboratory in Norwich, UK — took … Continue reading Authors retract two plant biology papers over duplicated images

“Clumsy but genuine errors” prompt PNAS correction

Some accidental mistakes have led researchers to issue a long correction to a 2016 PNAS paper. According to the notice, when the cell biology paper’s corresponding authors became aware of duplications in two images, they immediately notified the journal and the University of Nottingham. After examining the original data archives, the university found that the … Continue reading “Clumsy but genuine errors” prompt PNAS correction

Drug researcher up to ten retractions

A pharmaceutical researcher has received his tenth retraction. The reason, once again: duplicating his previous work.
