Stem cell scientist appealing dismissal loses another paper

A once-prominent stem cell biologist, who recently lost both her job and a sizable grant, has lost her fifth paper. Recently, Molecular and Cellular Biology retracted a 2003 paper by Susana Gonzalez. Last February, the National Center for Cardiovascular Research (CNIC) in Spain dismissed her from her position over allegations of misconduct. The reason: suspicions … Continue reading Stem cell scientist appealing dismissal loses another paper

Project to “fact check” genetic studies leads to three more retractions. And it’s just getting started.

A project to identify studies doomed by problematic reagents has triggered three more retractions, bringing the total to five. Jennifer Byrne, a scientist at the University of Sydney, who developed the the idea of double-checking the nucleic acid sequences of research materials — thereby ensuring studies were testing the gene in question — told Retraction … Continue reading Project to “fact check” genetic studies leads to three more retractions. And it’s just getting started.

Two more retractions for former US prof who altered dozens of images

Two journals have retracted papers by a biologist who was recently found guilty of misconduct by his former employer, the University of Colorado Denver, bringing the total to five.

Authors withdraw study, citing “accidentally duplicated” images

Researchers in Australia have withdrawn a 2006 paper in The Journal of Biological Chemistry (JBC), citing image duplication. In the withdrawal notice, published July 14, 2017, the authors claim that the “errors do not impact the underlying scientific findings of the article.” Although the notice does not mention an investigation, a comment on PubPeer on March … Continue reading Authors withdraw study, citing “accidentally duplicated” images

This offense is the second we know of for the corresponding author, Uttam Chand Banerjee, in the same journal, Applied Microbiology and Biotechnology. Last year, Banerjee—who works at National Institute of Pharmaceutical Education and Research (NIPER) in Mohali, Punjab, India—had a 14-year-old review … Continue reading Author who previously claimed plagiarism was a mistake earns new erratum

Journal flags four papers by researcher in Spain over figure issues noted on PubPeer

A journal has issued expression of concerns (EOCs) for four papers after a concerned reader notified the editors of issues in several figures. According to the EOCs, the Journal of Cell Science (JCS) discussed the concerns with the corresponding author, José Ignacio Rodriguez-Crespo, and subsequently notified his institution, Complutense University of Madrid. Last year, all … Continue reading Journal flags four papers by researcher in Spain over figure issues noted on PubPeer

Author cops to “randomly” choosing data for figures in paper, colleagues say

On April 17th, Mathieu Bollen, a researcher at KU Leuven in Belgium, received a notice from PubPeer: A paper he had published in 2013 appeared to have data duplications. The article, “Maternal Embryonic Leucine Zipper Kinase (MELK) Reduces Replication Stress in Glioblastoma Cells,” published in the Journal of Biological Chemistry, offered an explanation for why … Continue reading Author cops to “randomly” choosing data for figures in paper, colleagues say

Carlo Croce, OSU cancer researcher under investigation, retracts paper

A researcher whose work has come under repeated scrutiny has retracted a 2008 paper for “errors that occurred in the construction” of various figures. Carlo Croce, the corresponding author of the newly retracted paper, has been dogged by misconduct accusations for years — as recently described in the New York Times. His employer, The Ohio … Continue reading Carlo Croce, OSU cancer researcher under investigation, retracts paper

When is a citation not enough?

Last year, Boris Ratnikov was reading a paper and saw a familiar image. He quickly realized: The image was from a 2012 paper he’d written, but wasn’t cited. The 2016 Cell Metabolism paper he was reading had copied a figure from his 2012 PLOS ONE paper without referencing it.  In September 2016, Ratnikov, who is … Continue reading When is a citation not enough?
