A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

cancer cell 9-13MIT’s Robert Weinberg, a leading cancer researcher who retracted a Cancer Cell paper earlier this year for “inappropriate presentation” of figures, has corrected a different paper in the same journal.

Here’s the correction for “Species- and Cell Type-Specific Requirements for Cellular Transformation:”

We were apprised recently of errors made in the assembly of Figures 2B, 3A, 4A, 4B, and 5G, resulting in the incorporation of incorrect representative images in these figures. These errors occurred during the electronic assembly and have no bearing on the conclusions of the study. The corrected figures are shown below. The authors apologize for any possible confusion this might have caused.

Here’s the original Figure 2 and caption, followed by the new version (read all the way to the end of the post for more details on how this came to light): Continue reading A Cancer Cell mega-correction for highly cited researcher who retracted paper earlier this year

Doing the right thing: Researchers retract quorum sensing paper after public process

We’ll say it again: We like being able to point out when researchers stand up and do the right thing, even at personal cost.

In December 2011, Pamela C. Ronald, of the University of California, Davis, and colleagues published a paper in PLOS ONE,”Small Protein-Mediated Quorum Sensing in a Gram-Negative Bacterium.” Such quorum sensing research is a “hot topic” right now, so not surprisingly the paper caught the attention of other scientists, and the media, including the Western Farm Press. The study has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

One of those scientists who took notice was Ronald’s UC Davis colleague Jonathan Eisen, who posted about the paper on his blog. That was on January 9, 2012. But if you go to that post today, you’ll see that Eisen struck through most of it, and added this comment: Continue reading Doing the right thing: Researchers retract quorum sensing paper after public process

Journal retracts two papers after being caught manipulating citations

pibbEarlier this week, in a story by Richard van Noorden, Nature revealed the hidden workings of a scheme referred to as “citation stacking” that has landed a number of journals in trouble. The story begins:

Mauricio Rocha-e-Silva thought that he had spotted an easy way to raise the profiles of Brazilian journals. From 2009, he and several other editors published articles containing hundreds of references to papers in each others’ journals — in order, he says, to elevate the journals’ impact factors.

As Nature reports, Rocha-e-Silva was apparently frustrated that Brazilian government agencies were relying heavily on impact factor to evaluate graduate programs. That meant few scientists were willing to publish in Brazilian journals, which had lower impact factors. Rocha-e-Silva describes some of these frustrations in an impassioned 2009 editorial (in Portuguese). Continue reading Journal retracts two papers after being caught manipulating citations

Doing the right thing: Researchers retract two studies when they realize they misinterpreted data

protein scienceWhat do you do when new experiments show that you interpreted the data from your old experiments the wrong way?

Some scientists might just shrug and sweep those errors — and their previous papers — under the rug. But when it happened to Jeffery Kelly, of the Scripps Research Institute, and his colleagues, they decided to retract their earlier work.

Here’s the abstract of their new paper (we bolded a few sentences for emphasis): Continue reading Doing the right thing: Researchers retract two studies when they realize they misinterpreted data

Retraction appears for Harvard scientist who had two mega-corrections last year

molecular cellSam Lee, a Harvard biologist who had two mega-corrections published last year, has retracted a paper in Molecular Cell because some of the figures were “inappropriately assembled.”

Here’s the notice for “GAMT, a p53-Inducible Modulator of Apoptosis, Is Critical for the Adaptive Response to Nutrient Stress:” Continue reading Retraction appears for Harvard scientist who had two mega-corrections last year

Case Western dermatology department hit with second ORI sanction within 6 months

The Office of Research Integrity (ORI) has sanctioned an assistant professor of dermatology at Case Western Reserve University in Cleveland for plagiarizing from a grant application she was reviewing — which feels like a scientific version of insider trading — and a number of published papers.

According to the ORI’s findings, Pratima Karnik Continue reading Case Western dermatology department hit with second ORI sanction within 6 months

A sad postscript: Paper by deceased researcher retracted

cancer researchIt was the last study ever published from prominent scientist Gerd Maul’s lab. And now it’s been retracted.

Maul was a highly cited cell biologist, with 30 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge. He was also a well-known sculptor. When he died in 2010, he had a paper under submission at Cancer Research, which was published late that year.

This year, however, his co-authors found problems with the study. And as the notice — one of the most detailed we’ve ever seen — explains: Continue reading A sad postscript: Paper by deceased researcher retracted

Tokyo panel calls for retraction of 43 Kato papers

katoThe University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.

If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]

The Asahi report quotes Kato — who has received some $20 million in government funding for his work  — as acknowledging problems with the data in his studies: Continue reading Tokyo panel calls for retraction of 43 Kato papers
