The retraction count for Dipak Das, the resveratrol researcher whom the University of Connecticut found to have committed 145 counts of fabrication and falsification of data, has risen to eight with withdrawals by Free Radical Biology & Medicine and Free Radical Research.

The two Free Radical Biology & Medicine retractions, for “Expression of the longevity proteins by both red and white wines and their cardioprotective components, resveratrol, tyrosol, and hydroxytyrosol” (cited 38 times, according to Thomson Scientific’s Web of Knowledge) and “Redox regulation of resveratrol-mediated switching of death signal into survival signal” (cited 32 times), are carefully detailed and read the same way: Continue reading Three more retractions for resveratrol researcher Dipak Das, in free radical journals

Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data

The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.

According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.

UConn resveratrol researcher Dipak Das fingered in sweeping misconduct case

Das, via UConn

The University of Connecticut, in what clearly seems like an attempt to get ahead of damaging news, has announced an “extensive” investigation into research misconduct involving one of its scientists, Dipak K. Das.

According to a press release, the university has notified 11 journals that published Das’ work about the alleged fraud. One area of interest for Das, a government-funded professor of surgery and director of the Cardiovascular Research Center, has been resveratrol, a substance in red wine that has allegedly been linked to improved cardiac health.

The university touted some of his early efforts in this field.

Retraction by reason of insanity? A look at a 60-year-old entomology paper

By now, Retraction Watch readers are familiar with papers that are withdrawn because of faked data. Those cases may involve pressure cooker environments, bad seeds, or both, but they’re usually intentional. But what if a researcher fabricated findings without even knowing it?

That’s the idea behind a provocative paper just published online in Science and Engineering Ethics. In it, Matan Shelomi, a graduate student in entomology at the University of California, Davis, describes the case of Jay Traver, an entomologist who, in 1951, published a description of her experiences with “a mite infestation of her scalp that resisted all treatment and was undetectable to anyone other than herself” in the Proceedings of the Entomological Society of Washington (PESW). As Shelomi notes: Continue reading Retraction by reason of insanity? A look at a 60-year-old entomology paper

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

Bugging out: An opaque retraction notice reveals why an entomology journal only looks dark

We hope it doesn’t bug Retraction Watch readers that we’ve been writing about entomology more than usual this week. That’s because a reliable tipster has been sending us material that checks out.  Here’s another case, of a retraction that appeared some months ago in Entomological News. The retraction notice itself revealed little, but we did learn why the journal hasn’t published an issue in more than a year.

Here’s the notice: Continue reading Bugging out: An opaque retraction notice reveals why an entomology journal only looks dark

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

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
