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

Lancet retracts Jikei Heart Study of valsartan following investigation

When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

colloids and surfaces bThe journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists.

The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” was written by authors from various institutions in Tamil Nadu, and appeared online in December 2011 and in print the following April. It has been cited three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the abstract: Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

Case report: An 85-year-old man eats some chicken and unknowingly swallows a bone. After two days of worsening abdominal pain, he shows up to the emergency room. A CT scan reveals the bone perforating his colon. He is rushed to surgery, which is successful. Then, during his otherwise uneventful recovery, he develops female breasts.

That’s not exactly the case report that showed up in the International Journal of Surgical Case Reports earlier this month, but then again, the images in the relevant case report aren’t exactly of someone’s colon, either.

With a warning that the clinical images below are mildly NSFW, here’s Figure 1 from the cleverly titled “Chicken or the leg: Sigmoid colon perforation by ingested poultry fibula proximal to an occult malignancy:” Continue reading Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

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

Irony alert: Authors lose paper in loss prevention journal for plagiarism

losspreventionIf it seems that we write “irony alert” often, well, can you blame us? The Journal of Loss Prevention in the Process Industries (we’ll call it JLPPI for short) has retracted a paper it published earlier this year for plagiarism from multiple sources.

The article, “FTA vs. Tripod-Beta, which seems better for the analysis of major accidents in process industries?” was written by two occupational health researchers at Hamadan University of Medical Sciences in Iran. According to the abstract:

Paper retracted because images “were, in fact, electron microscopy results of totally different catalysts”

catcommA group of chemical engineers in China has retracted their article on photocatalysts after alerting the journal that images in the paper did not show what they’d reported.

The article, which appeared in Catalysis Communications earlier this year, was titled “Synthesis and characterization of novel Cu2O/PANI composite photocatalysts with enhanced photocatalytic activity and stability,” and was written by Xiufang Wang, Guangmei Chen and Jun Zhang of the School of Materials and Chemical Engineering at Anhui University of Architecture, in Hefei.

Here’s the retraction notice: Continue reading Paper retracted because images “were, in fact, electron microscopy results of totally different catalysts”

Penkowa notches fourth retraction, in Experimental Neurology

exp neuroMilena Penkowa, the Danish neuroscientist who resigned from the University of Copenhagen in December 2010 amid suspicions of misconduct, has had another paper retracted.

The new retraction appears in Experimental Neurology. Here’s the notice for “M-CSF deficiency leads to reduced metallothioneins I and II expression and increased tissue damage in the brain stem after 6-aminonicotinamide treatment”: Continue reading Penkowa notches fourth retraction, in Experimental Neurology

That face rings a bell, but where have I published it before?

ieriprocediaIrony alert: If you’re going to write a paper about face recognition technology, well, do we really need to go on?

A group of researchers in Wuhan, China, evidently didn’t quite realize they were walking into a ridicule trap when they agreed to have their paper, “Face Recognition with Learning-based Descriptor,” published in IERI Procedia. The article appeared in 2012 and was part of an issue devote to that year’s International Conference on Future Computer Supported Education, which took place in Seoul.

And now comes this: Continue reading That face rings a bell, but where have I published it before?

Anticancer-fungus paper retracted because some of the results “may be inaccurate”

biomacroMaybe it was a case of hitting the “send” button a bit too soon, or maybe it was a spasm of seller’s remorse, but a group of Chinese researchers has retracted a paper they’d published preliminarily a few months earlier.

The paper, “Antitumor and immunomodulatory activity of a polysaccharide from fungus Coprinus comatus (Mull.:Fr.) Gray,” by a group from various institutions in Shaanxi, appeared in April on the website of International Journal of Biological Macromolecules (as what appears to have been an uncorrected proof). But that didn’t stick.

According to a retraction notice dated August 2nd: Continue reading Anticancer-fungus paper retracted because some of the results “may be inaccurate”
