Author retracts PNAS paper about alleged Pliocene cheetah fossil that critics said was a fake

A paper about an alleged cheetah fossil from the Pliocene epoch, dogged by questions since its publication in 2008, has been retracted after one of the authors acknowledged it wasn’t what they thought it was.

Here’s the notice for the paper, “A primitive Late Pliocene cheetah, and evolution of the cheetah lineage:Continue reading Author retracts PNAS paper about alleged Pliocene cheetah fossil that critics said was a fake

Psychological Science retracts a Sanna paper, citing lawyers, COPE…and Retraction Watch

In April 2011, we praised Psychological Science for its handling of a retraction. At the time, we went as far as to call the retraction notice a “model” of transparency for other journals to follow.

Well, they evidently took that compliment seriously, according to a new retraction notice for a paper by Lawrence Sanna. Sanna left Michigan under a cloud a few months ago after another scientist found his data statistically implausible, as Ed Yong reported in Nature.

The newly retracted paper, “Construing collective concerns: Increasing cooperation by broadening construals in social dilemmas,” was published in 2009 while Sanna was still at the University of North Carolina-Chapel Hill. Here’s a sample from the abstract: Continue reading Psychological Science retracts a Sanna paper, citing lawyers, COPE…and Retraction Watch

Statins without prescription website paper retracted after company says it requires scripts, threatens suit

The authors of a paper on websites that sell cholesterol-lowering statin medications without prescriptions have retracted it. The move followed the threat of a lawsuit against the journal by a company included in the study that says it never dispenses sans a script.

Here’s the notice: Continue reading Statins without prescription website paper retracted after company says it requires scripts, threatens suit

Ovarian transplant update: Authors of 2004 live-birth follow-up letter ask Lancet to retract it

Yesterday, we brought you news of a story in Belgium involving questions about whether a woman who gave birth following an ovarian transplant could have become pregnant without the transplant. The case, which led to a university investigation but no retraction, included allegations of theft and arson.

This morning, we were made aware of a request for a retraction from The Lancet related to other work by Jacques Donnez, the obstetrician-gynecologist at the center of the case. In 2004, Donnez and colleagues published what they said was the first pregnancy using frozen banked ovarian tissue in The Lancet. The paper has been cited hundreds of times, but not everyone agreed with Donnez et al’s assessment at the time. All but one of the authors of a Lancet letter — colleagues of Donnez’s at the Catholic University of Louvain — describing the perinatal follow-up of the woman now say they don’t either, and want to retract their letter.

In their letter requesting retraction, published in the journal on July 14, Corinne Hubinont and colleagues write that they “did not have access to the patient’s gynaecological records throughout the pregnancy,” but that “Recently, we had the opportunity to read the patient’s notes,” which include a progesterone measurement “omitted by Donnez and colleagues:” Continue reading Ovarian transplant update: Authors of 2004 live-birth follow-up letter ask Lancet to retract it

Fireworks: Belgian dispute over ovarian transplant findings includes claims of theft, arson

There’s a story brewing in Belgium that is, as one local newspaper put it, worthy of a TV drama.

Here’s our attempt at a summary: Jacques Donnez, chair of Catholic University of Louvain’s (UCL) gynecology department, and colleagues published two studies in Human Reproduction in 2010. One study claimed to show that a woman had given birth after undergoing chemotherapy for severe sickle cell disease and then getting an ovarian transplant from her sister.

The other of those studies, the authors noted, confirmed “data published earlier as a case report” in 2007. That case report of a woman with another type of anemia — the pregnancy only went as far as an embryo, which did not survive — garnered a good deal of attention, because, as New Scientist reported: Continue reading Fireworks: Belgian dispute over ovarian transplant findings includes claims of theft, arson

Biochemistry journal retracts paper for being, well, less than conclusive

Here’s a new one that may stoke the debate about whether a paper deserves retraction merely for being wrong or less than fully right.

The journal Cell Biochemistry and Function, a Wiley title, has retracted an article it published earlier this year by a pair of Chinese authors — or, rather, from one author an an unwitting co-author. That authorship issue alone should be enough to warrant a retraction. But the retraction notice also includes a more interesting matter: Continue reading Biochemistry journal retracts paper for being, well, less than conclusive

Another retraction for potential prostate cancer test from Hopkins

Earlier this year, we reported on the case of Robert Getzenberg of Johns Hopkins, who retracted a 2007 paper in Urology that was “at the center of two 2009 lawsuits brought by a company that funded the work.”

Getzenberg has now retracted a related paper,  “Analysis of a serum test for prostate cancer that detects a second epitope of EPCA-2,” published in The Prostate in 2009 and cited nine times, according to Thomson Scientific’s Web of Knowledge.

The notice in The Prostate goes further than the one in Urology, using the word “falsification:” Continue reading Another retraction for potential prostate cancer test from Hopkins

Two retractions in biophysics journal, one because article is “too preliminary and potentially misleading”

We’ve seen vigorous debates here on Retraction Watch about when studies should be retracted. Does it require fraud? Just not being reproducible? Somewhere in between?

Given the apparent divergence of opinions on the issue, we thought it would be worth highlighting a case that involves language we haven’t seen before. Here’s the notice for “Apoptosis of CT26 colorectal cancer cells induced by Clostridium difficile toxin A stimulates potent anti-tumor immunity,” which originally appeared online in Biochemical and Biophysical Research Communications in April: Continue reading Two retractions in biophysics journal, one because article is “too preliminary and potentially misleading”

Three papers by German management prof retracted for duplication, statistical issues

Ulrich Lichtenthaler, a management professor in Germany, has had three papers retracted by two different journals, after readers noticed statistical irregularities.

Lichtenthaler was at the WHU – Otto Beisheim School of Management when he published the papers in 2009 and 2010. He is now at the University of Mannheim. The retraction in Strategic Organization was first reported by the Strategy Profs blog. It reads: Continue reading Three papers by German management prof retracted for duplication, statistical issues

Group retracts microRNA paper after realizing reagent was skewing results

A retraction from a high-profile group uncovered a technical limitation involving a widely used reagent.

Some quick background: the sequence hypothesis central hypothesis dogma of biology states that DNA gets transcribed to RNA that gets translated into proteins. Some RNAs, however, don’t code for proteins, but instead help to regulate gene expression. These microRNAs are tiny in size, but can regulate gene expression across animal and plant kingdoms.

In September 2011, the Molecular Cell published an entire issue with regulatory RNA as its theme. V. Narry Kim, associate professor at Seoul National University and high-profile microRNA researcher contributed a study that her group has now retracted just months later on June 29.

The problem? A reagent used to purify miRNAs favors some miRNAs and fails to isolate those rich low in guanine and cytosine — two of the four building blocks of RNA — or those with few secondary folding structures.
