Retraction comes as death of PI leads to lost records

The Journal of Experimental Medicine has retracted a 2011 article after the principal investigator’s home institution suggested that the PI might have manipulated his data. Complicating matters, the PI in this case died two weeks after the paper appeared and his notes have gone missing — making an affirmative declaration of fraud or honest error difficult.

Here’s the notice: Continue reading Retraction comes as death of PI leads to lost records

A retraction as a group’s papers on smoking and weight loss are too close for comfort

The American Journal of Physiology Endocrinology and Metabolism is retracting a 2009 article by Japanese researchers who appeared to be so fond of their data they published them thrice.

The paper, “Dual suppression of adipogenesis by cigarette smoke through activation of the aryl hydrocarbon receptor and induction of endoplasmic reticulum stress,” by Masanori Kitamura and colleagues, looked at the biochemical mechanism by which cigarette smokers seem to be able to keep weight off. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

But according to the retraction notice: Continue reading A retraction as a group’s papers on smoking and weight loss are too close for comfort

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

Two detailed retraction notices appear in PNAS

We’ve fallen a bit behind in our coverage of retractions in the Proceedings of the National Academy of Sciences (PNAS), so we wanted to call attention to two very helpful ones from recent months.

Here’s one notice, which appeared online on August 5: Continue reading Two detailed retraction notices appear in PNAS

That’s a Mori! Seven more retractions brings latest count to 30

The other day we reported that Naoki Mori had lost his 23rd paper to retraction for image manipulation and duplication. Turns out we were wrong by a pretty wide margin.

The International Journal of Cancer has retracted seven more articles by the disgraced Japanese researcher, all for the same reasons:

The following article has been retracted through agreement between the first author and several coauthors, the journal Editor in-Chief, Peter Lichter, and John Wiley & Sons, Ltd. … After an investigation the retraction has been agreed due to inappropriate duplication of images and overlap with other published work.

The papers are as follows: Continue reading That’s a Mori! Seven more retractions brings latest count to 30

“Ill communication” leads to retraction of tissue paper (sorry) for authorship issues

Like many researchers, Frank Walboomers frequently checks the scientific databases to see when his latest publications appear. He was doing so a few months ago when he came across his name on an article — “Effects of pro-inflammatory cytokines on mineralization potential of rat dental pulp stem cells” — published online in July in the Journal of Tissue Engineering and Regenerative Medicine, that he hadn’t written.

The first author of the paper, Xuechao Yang, was a former doctoral student in Walboomers’ laboratory at Radboud University Nijmegen. It didn’t take Walboomers long to figure out what had happened: Continue reading “Ill communication” leads to retraction of tissue paper (sorry) for authorship issues

You can do that? A massive correction in Nature, but no retraction

This past April, Amparo Acker-Palmer and colleagues published a study in Nature, “Ephrin Bs are essential components of the Reelin pathway to regulate neuronal migration.” Within a day of its publication, Nature readers were raising questions about many of its figures. They started like this:

Andy Gu said:

Looks like Fig 1a, the two middle figures are actually the same with little move from desired regions. I don’t trust their data now…..

After several such comments, Nature senior editor Noah Gray weighed in: Continue reading You can do that? A massive correction in Nature, but no retraction

Unveiled: Anonymous researcher found guilty of fraud in Canadian funding agency documents

Margaret Munro, a Postmedia News reporter whose work we’ve had the chance to admire before, has a few great stories running in Canadian papers today about what happened in some recent scientific fraud investigations.

She bases the stories on  Natural Sciences and Engineering Research Council (NSERC) documents obtained under a freedom of information request. NSERC — which provides $1 billion per year for research — seems to have gone far out of its way to keep the names of the researchers a secret.

In one set of heavily redacted documents, however, they did mention a December 2008 retraction. As Retraction Watch readers know, we investigate retractions…well, not exactly for a living, but we sure spend a lot of time doing it. So we threw ourselves at our favorite database and made some connections.

Long story short: We’re quite sure we’ve found the unnamed researcher. Continue reading Unveiled: Anonymous researcher found guilty of fraud in Canadian funding agency documents

Nature Medicine paper by former Montreal Heart Institute researcher Zhiguo Wang unlikely to be retracted

We’ve been reporting on the case of Zhiguo Wang, the Montreal Heart Institute researcher who was dismissed earlier this month for scientific misconduct. In the announcement about Wang’s dismissal, the institute said it had requested the retraction of three papers other than the two that Wang had himself retracted earlier this summer, making a total of five.

We’ve been following up with journals that published Wang’s work, with the help of eagle-eyed Retraction Watch readers, and last week reported on the first of those three additional retractions, in the Journal of Cell Science. Late last week, we heard from Juan Carlos Lopez, the chief editor of Nature Medicine, which had published a paper by the group. Lopez had earlier said he was waiting for a Montreal Heart Institute report on their findings. He tells us it’s unlikely the Nature Medicine paper will be among those retracted: Continue reading Nature Medicine paper by former Montreal Heart Institute researcher Zhiguo Wang unlikely to be retracted

Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science

We’re following the case of a group that recently retracted a Nature Immunology paper for figure irregularities, soon after being forced to correct images in a Science paper for similar reasons.

The Nature Immunology paper, “The helminth product ES-62 protects against septic shock via Toll-like receptor 4–dependent autophagosomal degradation of the adaptor MyD88,” has been cited just twice since it appeared online in February 2011, according to Thomson Scientific’s Web of Knowledge. The retraction notice, which appeared online on July 19: Continue reading Group retracts Nature Immunology paper for figure irregularities after posting a correction to Science
