bichaw_v052i049.inddWe’ve found a third retraction for Karel Bezouška, the Czech scientist, who, as we reported this summer, broke into a lab in an attempt to tamper with experiments trying to replicate his own falsified data.

The article, “Molecular Characterization of Binding of Calcium and Carbohydrates by an Early Activation Antigen of Lymphocytes CD69,” had appeared in 2003 in Biochemistry. and has been cited 29 times, according to Thomson Scientific’s Web of Knowledge.

Journal takes different tacks on two cancer papers with image problems

carcinogenCarcinogenesis has the publishing world’s version of a twin problem: two dysfunctional articles yet one gets retracted while the other merely suffers a correction. Is it nature — or nurture?

Here are the details. One article, “Chemopreventive effect of dietary glutamine on colitis-associated colon tumorigenesis in mice,” came from a group in China. Published earlier this year, the authors seem to have had some trouble with their figures. As the corrigendum explains:  Continue reading Journal takes different tacks on two cancer papers with image problems

Should scientific misconduct be handled by the police? It’s fraud week at Nature and Nature Medicine

naturemed1213It’s really hard to get papers retracted, police might be best-equipped to handle scientific misconduct investigations, and there’s finally software that will identify likely image manipulation.

Those are three highlights from a number of pieces that have appeared in Nature and Nature Medicine in the past few weeks. Not surprisingly, there are common threads, so join us as we follow the bouncing ball. Continue reading Should scientific misconduct be handled by the police?

A retracted retraction? Authors salvage entomology paper with image issues

jtbThe paper is dead. Long live the paper!

Earlier this year, we brought you the case of a group of Brazilian insect researchers who lost two 15-year-old papers in different journals for duplication. One of those papers has been resurrected, albeit in a rather puzzling way.

The article, “Non-local interactions and the dynamics of dispersal in immature insects,” had appeared in the Journal of Theoretical Biology, which had issued the following retraction notice:

Nature Medicine retracts MS paper with ghost data by former GSK researcher

naturemed1213Nearly six months after first expressing concern about the validity of a 2010 paper on multiple sclerosis, Nature Medicine has retracted the article for containing “erroneous” data — which in this case don’t seem to have existed, making them more fabricated than wrong.

The paper, “Crucial role of interleukin-7 in T helper type 17 survival and expansion in autoimmune disease,” came from a group led by Jingwu Zhang, who at the time ran GlaxoSmithKline’s Research and Development Center in Shanghai.

In June, the journal issued an expression of concern about the article after readers discovered problems with the data, as reported by Nature Medicine’s blog.

Same “difference,” as anesthesia paper retracted for plagiarism

Cover, Coverabbild, Titel, TitelbildA group of anesthesiology researchers in China has lost their 2011 paper in Der Anaesthesist because, well, the article wasn’t theirs to begin with.

The paper, “Different anesthesia methods for laparoscopic cholecystectomy,” came from authors at the 309th Hospital of PLA, in Beijing, who purported to report on a randomized trial of 68 patients undergoing laparoscopic colon surgery with either general or spinal (that is, a nerve block) anesthesia.
