Lawsuit couldn’t stop four retractions for diabetes researcher

Four expressions of concern in the journal Diabetes have turned into retractions for Mario Saad, a move which he had tried to stop with a lawsuit. Last August, a judge dismissed Saad’s suit against the American Diabetes Association, which publishes Diabetes, concluding that the expressions of concerns on the papers were not defamation, but part of an “ongoing … Continue reading Lawsuit couldn’t stop four retractions for diabetes researcher

Second of 3 retractions appears for biologist, the result of “a substantial number of falsifications”

A cell biologist who falsifed Western blots has notched a second retraction, with one more expected after a investigation at Nanyang Technological University in Singapore. First author Sudarsanareddy Lokireddy, now apparently a research fellow at Harvard, did not agree to the retraction, the result of “a substantial number of falsifications.” In December, we covered the results of the NTU … Continue reading Second of 3 retractions appears for biologist, the result of “a substantial number of falsifications”

Cancer Cell paper under investigation following anonymous queries on PubPeer

A Cancer Cell paper that caused a flurry of activity on the website PubPeer is under investigation, after the last author announced on the site that he’d requested a correction from the journal. The 2012 paper sparked a lively dialogue last month on the post-publication discussion site, as commenters questioned Western blot images in which … Continue reading Cancer Cell paper under investigation following anonymous queries on PubPeer

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

Science flags immune-boosting paper under investigation

Science magazine has issued an expression of concern for a paper on the discovery of a new immune-boosting protein. The paper’s findings, which received some press coverage when they came out last spring, are now under investigation by Imperial College London. The expression of concern follows a correction noting a Western blot mix-up. Science Editor in Chief Marcia McNutt told … Continue reading Science flags immune-boosting paper under investigation

Fifth retraction for Wayne State researcher who fudged figures

Another retraction has appeared for Teresita Briones, who used to study neuroscience at Wayne State University — the final of five papers flagged by the Office of Research Integrity for containing falsified data. According to the ORI notice published in May, Briones “intentionally, knowingly, and recklessly engaged in research misconduct by falsifying and/or fabricating data.” This … Continue reading Fifth retraction for Wayne State researcher who fudged figures

Singapore investigation leads to two retractions, two more on the way

Authors have retracted papers from Cell Metabolism and the Journal of Biological Chemistry after an investigation in Singapore found issues, including falsified data. The investigation is ongoing, and two additional retractions, along with two corrections, are on the horizon. The investigation looked into papers by first authors Sudarsanareddy Lokireddy, now a postdoc at Harvard, and Sandhya Sriram, a postdoc at the … Continue reading Singapore investigation leads to two retractions, two more on the way

Cancer researcher contributed “false data” to 11 studies

A former cancer researcher has falsified data in 11 studies, according to the results of a investigation scheduled to be published in the Federal Register tomorrow. The Office of Research Integrity’s findings are based on an inquiry at Virginia Commonwealth University, where Girija Dasmahapatra worked until July of this year, investigating possible therapies for cancer. The … Continue reading Cancer researcher contributed “false data” to 11 studies

MD Anderson researcher Aggarwal up to six corrections

A highly cited cancer researcher at MD Anderson has notched three major corrections, all associated with problems in figures. One note cites “human error” as the cause. Bharat Aggarwal is the last author on all three papers. He is now up to six corrections, two unexplained withdrawals, and two Expressions of Concern. He’s also threatened to sue us in the past, … Continue reading MD Anderson researcher Aggarwal up to six corrections

“Carelessness” forces Science to correct paper about immune booster

Science is fixing images in a paper published online in April that discovered an immune-boosting protein, after the authors mistakenly mixed up similar-looking Western blots. The paper, which received some press coverage, identified a protein that helped the immune system fight off cancers and infections. Philip Ashton-Rickardt, a scientist at Imperial College London who led the study, … Continue reading “Carelessness” forces Science to correct paper about immune booster
