Author who broke into lab to tamper with investigation now up to half a dozen retractions

Bioconjugate ChemistryKarel Bezouška, the scientist who tried to tamper with an investigation into his work by breaking into a lab refrigerator, has had his fifth and sixth papers retracted.

Here’s the notice from Bioconjugate Chemistry for 2012’s “Dimerization of an Immunoactivating Peptide Derived from Mycobacterial hsp65 Using N-Hydroxysuccinimide Based Bifunctional Reagents Is Critical for Its Antitumor Properties:” Continue reading Author who broke into lab to tamper with investigation now up to half a dozen retractions

Authors of “just make up an…analysis” Organometallics paper issue mega-correction

organometallicscoverBack in August we — and others — wrote about a paper in Organometallics for which one member of the study team appeared to have instructed a co-author to pad the article with artificial results. From the supplemental information (SI) of that paper:

Emma, please insert NMR data here! where are they? and for this compound, just make up an elemental analysis…

Now comes a correction statement from the group that can only be described as “mega.” First reported last month by Chemical & Engineering News, the lengthy notice begins: Continue reading Authors of “just make up an…analysis” Organometallics paper issue mega-correction

Leading chemist notches two retractions in one journal, separated by 47 years

inorganica chimica actaA leading chemist at the University of Washington, Larry Dalton, has retracted a 2004 study in Inorganica Chimica Acta, marking his second retraction in the journal in 47 years.

Here’s the new notice: Continue reading Leading chemist notches two retractions in one journal, separated by 47 years

Hanukkah it ain’t: Oil paper burns out as authors bicker

jos_63_2Forgive us for revisiting our family traditions, but the story of Hanukkah tells how the Maccabees managed to coax eight days worth of light from a day’s worth of olive oil. Some  Tunisian chemists are probably wishing their paper on olive oil had the same staying power.

But their 2013 article, in the Journal of Oleo Science — a publication of the Japanese Oil Chemists’ Society — has been retracted because the group evidently wasn’t much of a group after all.

The paper, “Effect of Storage on Refined Olive Oil Composition: Stabilization by Addition of Chlorophyll Pigments and Squalene,” purported to come from Ghayth Rigane, Mohamed Bouaziz, Sami Sayadi and Ridha Ben Salem, who work in Tunisia and have published together before on more than one occasion. As the abstract states: Continue reading Hanukkah it ain’t: Oil paper burns out as authors bicker

Brazilian researcher on 11 retracted papers loses academic post

ufmtDenis de Jesus Lima Guerra, a co-author on 11 chemistry papers that were retracted in 2011 for suspicions of fraud, has lost his position at the Federal University of Mato Grosso (UFMT).

Bernardo Esteves, who was first to report the news, writes (courtesy Google Translate) that the dismissal was Continue reading Brazilian researcher on 11 retracted papers loses academic post

‘Pseudoknots’ a pseudopaper, retracted for plagiarism

bioinformationlogoThe journal Bioinformation has retracted a 2009 article by a group of researchers from India.

The paper was titled “Targeting pseudoknots in H5N1 hemagglutinin using designed aptamers,” and was written by Priyanka Dhar, Sayak Ganguli and Abhijit Datta, of the Defence Institute of High Altitude Research and the Bioinformatics Centre at Presidency College in Kolkata.

Under a heading, “Reader Feedback”, the retraction notice states: Continue reading ‘Pseudoknots’ a pseudopaper, retracted for plagiarism

Science hasn’t retracted paper that university, NSF investigators wanted withdrawn

On Saturday, we highlighted a great two-part series by Joseph Neff of the News & Observer diving into the story of “Stefan Franzen, a chemistry professor at North Carolina State University who has been trying unsuccessfully to correct the scientific record.” Today, that series became a three-part series, with a new story revealing that an investigation by the National Science Foundation (NSF) Office of the Inspector General (OIG) had found “reckless” falsification in the work in question.

One of the key papers in the controversy was published by Lina A. Gugliotti, Daniel L. Feldheim, and Bruce E. Eaton in Science in 2004 and cited 125 times, according to Thomson Scientific’s Web of Knowledge. (Eaton is now at the University of Colorado at Boulder.) In 2011, Nature reported on the situation: Continue reading Science hasn’t retracted paper that university, NSF investigators wanted withdrawn

Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

jacsat_v136i001.inddKarel Bezouška, who, as we noted last year “broke into a lab refrigerator so he could tamper with samples being used to try to replicate the experiments during the investigation,” has had his fourth paper retracted.

Here’s the notice, for “Synthesis of Multivalent Glycoconjugates Containing the Immunoactive LELTE Peptide: Effect of Glycosylation on Cellular Activation and Natural Killing by Human Peripheral Blood Mononuclear Cells,” in the Journal of the American Chemical Society (JACS): Continue reading Karel Bezouška, who broke into lab to tamper with investigation, has JACS paper retracted

Fourth retraction for chemists in Iran

commnonlinsciWe’ve found a fourth retraction for a group of chemists in Iran who plagiarized.

As before, the offending article had appeared in Communications in Nonlinear Science and Numerical Simulation. This time, however, it did not include a co-author from Ball State University in Indiana, Robert Sammelson, whose name had appeared on three of the earlier papers. Continue reading Fourth retraction for chemists in Iran

More retractions for authors who duplicated — and did their own peer review

spectroscopylettersAdd to the retraction pile for a pair of chemists in Iran who duplicated their work — and reviewed their own articles to boot.

The authors, Kobra Pourabdollah and Bahram Mokhtari, are affiliated with the Razi Chemistry Research Center in the Shahreza Branch of Islamic Azad University. In September, we reported on the retractions of three articles by the researchers in Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry.

Readers then alerted us to five other retractions in the Journal of Coordination Chemistry — although these papers did not appear (at least by the retraction notice) to have involved self-reviewing.

The duo now also has lost a 2012 article in Spectroscopy Letters: An International Journal for Rapid Communication. , which has been cited twice, according to Thomson Scientific’s Web of Knowledge. According to the notice: Continue reading More retractions for authors who duplicated — and did their own peer review
