For months, a researcher has wrestled with a journal over the wording of an upcoming retraction notice. It appears that she has lost.
Earlier this week, Cell retracted the paper, despite the protests of first author Shalon Babbitt Ledbetter. When Ledbetter learned the journal was planning to retract the biochemistry paper over image manipulations, but wouldn’t name the culprit in the notice, she shared her concerns on PubPeer. Although a 2015 letter sent to Cell from Saint Louis University identified last author Dorota Skowyra as responsible for multiple manipulations, the journal wasn’t planning to say Skowyra was responsible in the retraction notice. Which would leave all other authors — particularly Ledbetter — under a cloud of suspicion.
Now, Cell Press has finally retracted the paper, along with another paper in Molecular Cell that lists Skowyra as corresponding author. Both notices describe image manipulations that were investigated by Saint Louis University (SLU). Neither identifies who is responsible.
A researcher has retracted two 2014 papers, after discovering they had not gone through the proper approval process before being submitted.
The papers were part of a collaboration funded by the U.S. National Institutes of Health, which focused on solving protein structures. Adam Godzik, the senior author, told Retraction Watch that all papers had to be approved by a special committee before being submitted to a journal. Given the scale of the collaboration, the committee for the Joint Center for Structural Genomics (JCSG) would assess whether researchers who had made a previous contribution to the work should be added as authors.
A Nobel Laureate has retracted a 2016 paper in Nature Chemistry that explored the origins of life on earth, after discovering the main conclusions were not correct.
Some researchers who study the origins of life on Earth have hypothesized that RNA evolved before DNA or proteins. If true, RNA would have needed a way to replicate without enzymes. The Nature Chemistry paper found that a certain type of peptide — which may have existed in our early history — made it possible for RNA to copy itself.
But in subsequent experiments, Tivoli Olsen — a member of Szostak’s lab — could not reproduce the 2016 findings. When she reviewed the experiments from the Nature Chemistry paper, she found that the team had misinterpreted the initial data: The peptide in question did not appear to provide an environment that fostered RNA replication.
PLOS ONE has retracted two 2014 papers from a group of researchers, after an institutional investigation confirmed image duplication. Although the authors initially asked to correct the figures in the two papers, they ultimately agreed with the decision to retract.
Mrinal K. Maiti—an associate professor at the Indian Institute of Technology at Kharagpur and corresponding author on the two now-retracted PLOS ONE papers—also corrected a 2016 paper published in PLOS ONE over figure-related errors. Maiti is the only author in common to all papers.
What Caught Our Attention: A big peer review (and perhaps academic mentorship) fail. These researchers used the wrong anticoagulant for their blood samples, leading them to believe that certain blood components were fighting microbes. The authors counted the number of colonies to show how well or poorly Tuberculin mycobacteria were growing in cultures — but blood samples need anticoagulants to prevent clots before analysis, and they used an anticoagulant that actually prevented the microbes from colonizing. The authors (and reviewers) should have known this from Continue reading Caught Our Notice: Dear peer reviewer, please read the methods section. Sincerely, everyone
When Retraction Watch began in 2010, our co-founders Ivan Oransky and Adam Marcus quickly realized they couldn’t keep up with the hundreds of retractions that appeared each year. And the problem has only gotten worse — although we’ve added staff, the number of retractions issued each year has increased dramatically. According to our growing database, more than 1300 retractions were issued last year (and that doesn’t include expressions of concern and errata). So to get new notices in front of readers more quickly, we’ve started a new feature called “Caught our Notice,” where we highlight a recent notice that stood out from the others. If you have any information about what happened, feel free to contact us at firstname.lastname@example.org.
A biotechnology journal has corrected a 2006 paper after discovering duplication and plagiarism.
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 retracted in Applied Microbiology and Biotechnology after an investigation revealed the authors had plagiarized from numerous sources and failed to reference them. At the time, Banerjee told us that he and his co-authors took a few lines from other reviews and that omitting the references was “simply unintentional.” According to The Indian Express, Banerjee also faced plagiarism allegations in 2005, and was denied a prestigious fellowship in 2011 as a result.Continue reading Author who previously claimed plagiarism was a mistake earns new erratum
A former graduate student at the University of Hong Kong confessed to making “inappropriate modifications” to several figures in a 2013 paper in the Journal of Biological Chemistry (JBC).
According to the retraction notice, the authors identified issues in 13 images while reviewing the data; the paper’s first author, Yingying Lu, copped to manipulating the figures. Even though “these modifications did not change the results or interpretations of this work,” the authors requested the paper be retracted.
The paper’s corresponding author, Jainbo Yue, previously based at the University of Hong Kong and now at the City University of Hong Kong, had nothing to add to the retraction notice, and told us that a “third person” is repeating the key experiments.
Oct. 3, 2011, was the beginning of the end for Frank Sauer’s tenure at the University of California, Riverside. On that day, an anonymous emailer contacted Sauer’s institution with accusations that the biochemist had cooked his research in at least eight papers over a 16-year period.
Sauer was found to have doctored images in studies using government money — nearly $3 million of it. He went on to lose his position at UC Riverside, several papers to retraction, and, in May, a subsequent legal battle over the severity of the federal sanctions. Along the way, he concocted a fantastic tale of sabotage against German scientists (like himself), replete with poison-pen letters and fabricated credentials.
Retraction Watch has obtained a copy of UC Riverside’s report on the Sauer case through a public records request. The report, which is undated but which describes committee meetings and interviews from October 2011 to October 2012, lists 33 allegations of scientific misconduct against Sauer, 20 of which the committee determined to involve deception. Of the remaining 13, the committee either could not find proof of guilt or determined that the data were legitimate.
