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

Papers on potential cancer drugs retracted for image manipulation

ccr 9-13A group of researchers at the Einstein College of Medicine in the Bronx, New York has retracted two papers for image manipulation.

The retraction notices for “PM02734 (Elisidepsin) Induces Caspase-Independent Cell Death Associated with Features of Autophagy, Inhibition of the Akt/mTOR Signaling Pathway, and Activation of Death-Associated Protein Kinase” and “The Phosphatase Inhibitor Menadione (Vitamin K3) Protects Cells from EGFR Inhibition by Erlotinib and Cetuximab” say the same thing: Continue reading Papers on potential cancer drugs retracted for image manipulation

Ask Retraction Watch: Should these papers be retracted?

protein scienceLast week, we reported on a new paper by Scripps Research Institute researchers in which they described how two of their previous papers had been based on mistaken interpretations. The authors wrote in their new paper that they were retracting the earlier works, but the journal had told them the papers would be corrected instead.

We had asked Protein Science editor Brian Matthews for clarification, and he emailed us late last week:

Frontiers papers on GMO debate, diabetes retracted for improperly cited text

frontiers plantThe author of a review article on diabetes has been forced to retract the paper after it emerged that he failed to properly credit some of the text — an omission we generally associate with the word plagiarism.

The article, “Colonic flora, probiotics, obesity and diabetes,” was written by Paul Marik, of Eastern Virginia Medical School, and appeared in July 2012 in Frontiers in Endocrinology. It has been cited once, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction notice:

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

Author with six recent corrections retracts JBC paper questioned on PubPeer

jbc 8-23-13Rakesh Kumar, a professor at the George Washington University, has retracted a paper in the Journal of Biological Chemistry (JBC) that was recently questioned on PubPeer.

Here are Peer1’s comments from PubPeer about the paper, “Mechanism of MTA1 Protein Overexpression-linked Invasion:” Continue reading Author with six recent corrections retracts JBC paper questioned on PubPeer

Paper on “better-than-average effect” retracted for being, well, worse than average

pers soc psych bullPerhaps what Garrison Keillor says about people is also true of scientific papers:

Welcome to Lake Wobegon, where all the women are strong, all the men are good-looking, and all the children are above average.

There’s been another retraction in social psychology, but before you lump it together with the field’s problem children — read: Diederik Stapel — it seems to be an example of researchers coming forward about an honest error.

Here’s the notice for “The Motivated Self: Self-Affirmation and the Better-Than-Average Effect,” originally published last year in Personality and Social Psychology Bulletin: Continue reading Paper on “better-than-average effect” retracted for being, well, worse than average

Nano Letters retracts chopstick nanorod paper questioned this week on chemistry blogs

NANO LettersA chemistry paper on nanorods that became a lightning rod for criticism on chemistry blogs this week has been retracted.

Here’s the notice for “Chopstick Nanorods: Tuning the Angle between Pairs with High Yield,” originally published in June in Nano Letters by Rajasekhar Anumolu and Leonard F. Pease of the University of Utah: Continue reading Nano Letters retracts chopstick nanorod paper questioned this week on chemistry blogs

Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

bmj case reportsHisashi Moriguchi, who retracted two papers last year because he and his colleagues could not “guarantee the accuracy of the results and conclusions,” has now had another paper withdrawn — at least temporarily.

A notice on the paper, “Autologous human cardiac stem cells transplantation for the treatment of ischaemic cardiomyopathy: first study of human-induced pluripotent stem (iPS) cell-derived cardiomyocytes transplantation,” which appeared in BMJ Case Reports, now reads: Continue reading Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication
