Olivier Voinnet, a well-known plant scientist at the ETH in Zurich, has notched his 7th retraction for a highly cited paper. The 2003 paper was pulled when “additional image manipulations” came to light after The Plant Journal issued a correction earlier this year.
The retraction follows an investigation into — and then retraction of — several other papers co-authored by Voinnet. The authors originally corrected the paper after they learned one image had been duplicated, and repeating the experiment found the “same interpretation and conclusions” held true. But when the corresponding author learned of additional “data manipulation,” they decided to retract the paper altogether.
Here’s the retraction notice for “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus:”
The retraction comes at the request of Anna Ahimastos’s co-authors, following an investigation into her work by her former workplace, the Baker IDI Heart and Diabetes Institute. The investigation was not able to verify the data referenced in the letter, which includes a citation for a recently retracted JAMA paper.
The retraction note is similar to others for Ahimastos’s papers:
R K Chandra, self-proclaimed father of nutritional immunology (from www.drrkchandra.com)
Memorial University in Canada has released a five-year-old report of an investigation, confirming a former nutrition professor had committed misconduct in a 2001 paper.
The 53-page report — about Ranjit Kumar Chandra, a prominent and once-lauded researcher — focuses on a Nutrition paper that examined the effectiveness of vitamins patented by Chandra. The report, authored by MUN professor emeritus William Pryse-Phillips, lists 41 problems with the paper, which it concludes:
…was not in full compliance with the scientific, ethical, and/or integrity standards of Memorial University at the time.
The paper was retracted in 2005; the report is dated 2009. We asked Pryse-Phillips why the university took so long to release it. He told us:
The authors of a paper on supportive supervisors just want readers to “better understand the reported findings,” and so have issued multiple “clarifications” in a corrigendum note.
The paper’s author list includes one Fred Walumbwa, formerly an Arizona State University management researcher, some of whose work has succumbed to scrutiny in the the past two years. His current list: seven retractions, a megacorrection, an expression of concern, and now this.
A heart researcher who fabricated trial participants has notched a second JAMA retraction. The retraction comes at the request of her co-authors, after an investigation by her former employer wasn’t able to confirm that this study was valid.
In September, we learned that Anna Ahimastos, who used to work at Baker IDI Heart and Diabetes Institute in Melbourne, Australia, had “fabricated [records] for trial participants that did not exist” in a JAMA trial for a blood pressure drug, according to principal investigator Bronwyn Kingwell. That trial was retracted, along with a sub analysis.
An investigation by the institute found problems or sufficient doubt in several more publications. This second JAMA retraction is number 5 for Ahimastos, of 8 total expected.
The letter, published in 2001, argues that local anesthesia is a “safe, reliable, inexpensive, and practical alternative to the use of epidural, spinal, or general anesthesia” for outpatient knee surgery. But to support his point, he uses one of his papers that has since been retracted for data fabrication.
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.
Chronic fatigue syndrome researcher Judy Mikovits was scheduled to head is heading to court today, where a California judge will would decide whether or not to dismiss her lawsuit against fourteen people and two Nevada corporations.
(Note: This story has been updated. See below.)
Among the defendants: the Whittemore Peterson Institute in Reno, Nevada where Mikovits used to work; the institute’s cofounders, Annette and Harvey Whittemore; a colleague with whom she shares a retracted Science paper; and several members of California and Nevada law enforcement.
The complaint does not check the box next to “Money Demanded in Complaint”, but also lists $750,000 in the associated field:
A heart researcher who fabricated patient records for her studies on the blood pressure medication ramipril has earned her fourth retraction, and more are apparently on the way.
For readers who are new to this case: Things first unraveled for Anna Ahimastos when a subanalysis of a JAMA clinical trial revealed “anomalies,” triggering an investigation. After Ahimastos admitted to fabricating patient data, that JAMA paper and two others — including a small trial in Annals of Internal Medicine — were pulled. A spokesperson for her former employer, Baker IDI Heart & Diabetes Institute, told us last week that they have requested more retractions:
Five papers and one letter are in the process of being retracted.
