Second retraction arrives in Alirio Melendez case

Alirio Melendez, whose former employer, the National University of Singapore, is investigating about 70 of his papers, has retracted a second study. Here’s the notice for the 2010 Journal of Molecular Cell Biology paper, “Sphingosine-1-phosphate mediates proliferation maintaining the multipotency of human Adult Bone Marrow and Adipose Tissue-derived Stem Cells:” Continue reading Second retraction arrives in Alirio Melendez case

Science drops other shoe in Stapel case, retracts recent paper on chaos

At the beginning of November, Science issued an “editorial expression of concern” over a 2011 paper by the disgraced Dutch social psychologist Diederik Stapel, in the wake of an announcement by his former employer Tilburg University, that it had found evidence of fraud in Stapel’s body of work.

A month later, Science has gone the extra step, publishing a retraction notice by Stapel and his co-author, Siegwart Lindenberg. The notice, dated Dec. 1, 2011, makes it clear that Stapel acted alone in the matter: Continue reading Science drops other shoe in Stapel case, retracts recent paper on chaos

Zhiguo Wang retractions appear in the Journal of Cellular Physiology

Last month, we reported that the last three of six promised retractions by Zhiguo Wang, who was a researcher at the Montreal Heart Institute until the results of an Institute investigation forced him to resign in early September — would be in the Journal of Cellular Physiology. They’ve now appeared.

Here are the three notices, which are far more informative than the Journal of Biological Chemistry was — and which make it clear Wang acted alone: Continue reading Zhiguo Wang retractions appear in the Journal of Cellular Physiology

Chronic fatigue syndrome researcher Judy Mikovits arrested

Judy Mikovits, the embattled chronic fatigue syndrome researcher who was fired from her post at Reno, Nevada’s Whittemore Peterson Institute in September, was arrested yesterday in California.

The Ventura County, California Sheriff’s Department web site lists Mikovits under booking number 1259336, charged with a felony violation of California Penal Code section 1551.1, “Fugitive From Justice.”  This is that section, according to FindLaw: Continue reading Chronic fatigue syndrome researcher Judy Mikovits arrested

Breaking news: Prolific Dutch heart researcher fired over misconduct concerns

Don Poldermans, a leading heart specialist, has been fired over concerns that he committed research misconduct. According to a report on the website DutchNews.nl:

Erasmus University in Rotterdam has sacked a professor in cardio-vascular medicine for damaging the institution’s academic integrity and for ‘scientific misconduct’, the NRC reports on Thursday.

The professor is accused of faking academic data and compromising patient trust, the paper says. In particular, he failed to obtain patient consent for carrying out research and recorded results ‘which cannot be resolved to patient information,’ the university said.

Don Poldermans has spent years researching the risk of complications during cardio-vascular surgery and has some 500 publications to his name.

A spokesman for Poldermans told the paper he admitted not keeping to research protocols but denied faking data. Continue reading Breaking news: Prolific Dutch heart researcher fired over misconduct concerns

Expression of Concern for a Bulfone-Paus paper

Retraction Watch readers may recall the story of Silvia Bulfone-Paus, who has been forced to retract 12 papers and has another under review at Blood. All of that scrutiny came after an investigation by her home institution, Germany’s Borstel Institute, that found evidence of image manipulation.

The latest development is perhaps no surprise. It concerns a review Bulfone-Paus and her colleagues published in BioEssays in 2006. Here’s the Expression of Concern, which was published online in July but just came our attention (we’ve added links to our coverage of specific retractions): Continue reading Expression of Concern for a Bulfone-Paus paper

Science expresses “concern” about Stapel paper

A day after Tilburg University released its preliminary report on psychologist Diederik Stapel, Science has issued an “expression of concern” about one of his papers.

The 2011 article, titled  “Coping with Chaos: How Disordered Contexts Promote Stereotyping and Discrimination,” was written by Stapel and Siegwart Lindenberg, a Tilburg colleague with an appointment at the University of Groningen.

Here’s the notice, signed by Science editor Bruce Alberts: Continue reading Science expresses “concern” about Stapel paper

Stapel report finds faked data in at least 30 papers, possibly more

Our comment threads lit up today with news that the interim report on the misconduct investigation into Diederik Stapel has arrived — and what it says ain’t pretty. Continue reading Stapel report finds faked data in at least 30 papers, possibly more

National University of Singapore official who co-authored Melendez papers won’t be part of investigation

The Alirio Melendez case is likely to become quite complicated, as the National University of Singapore (NUS) looks into about 70 papers by the researcher whose work has already been the subject of a retraction and Expression of Concern. One such wrinkle seemed to have already surfaced when a blog called the Gigamole Diaries pointed out last week that an NUS dean apparently connected to the investigation had co-authored two papers with Melendez:

…the authorship list for Melendez papers reads almost like a Who’s Who in the medical school, and includes heads of departments, Vice Deans and prominent individuals in the office of the NUS Vice President. Interestingly Prof Barry Halliwell, who is NUS Deputy President (Research and Technology), and who has been cited as fronting the investigation into the Melendez publications is himself associated with at least 2 Melendez publications.

We checked with Halliwell, who has indeed spoken to numerous media outlets about the investigation. He tells us: Continue reading National University of Singapore official who co-authored Melendez papers won’t be part of investigation

Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology

We’ve been following the case of Zhiguo Wang, the former Montreal Heart Institute researcher who was forced to resign his post in early September following an investigation into his work. At the time of that announcement, two retractions of the Wang group’s papers — which we had reported on in August — had appeared. The Institute said they had requested three more.

We figured that meant a total of five, although the Institute wouldn’t say which they were. So when we found out about a third retraction, in the Journal of Cell Science, we said it was the first of the remaining three.

We were wrong. Continue reading Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology
