An ecologist in Australia realized a database he was using to spot trends in extinction patterns was problematic, affecting two papers. One journal issued an expression of concern, which has since turned into a retraction. So far, the other journal has left the paper untouched.
The now-retracted paper concluded that medium-sized species on islands tend to go extinct more often than large or small mammalian species. But a little over a year ago, Biology Letters flagged the paper with an expression of concern (EOC), noting “concerns regarding the validity of some of the data and methods used in the analysis.”
Chem paper “the product of intentional, knowing, or reckless falsification, fabrication, and plagiarism”
According to the retraction notice in RSC Advances, the first author submitted the paper without the knowledge of the other two co-authors, and the paper was falsified, fabricated, and plagiarized. The notice cites a probe at the University of Tennessee (UT) at Knoxville — where all three listed authors are based — that concluded the study’s findings were invalid.
According to the EOC, published in RSC Advances, the paper is now under investigation.
The corresponding author of the study that detected toxic leaks from the work of prominent British artist Damien Hirst has now retracted it — but most of his co-authors disagree with the decision.
The April Analytical Methods study was covered extensively by the media when it suggested staff at Damien Hirst’s 2012 exhibition at Tate Gallery in London of dead animals embalmed in formaldehyde were being exposed to higher than recommended levels of the carcinogen.
Tate and Hirst’s company, Science Limited, immediately objected to the results; we’ve obtained what appears to be letter from a lawyer for Science Limited to the corresponding author of the paper — Pier Giorgio Righetti of the Polytechnic University of Milan in Italy — saying it was “deeply concerned and troubled by the claims” in the paper.
Last month, the journal issued an expression of concern (EOC) for the paper, nothing the data may not be reliable, and on July 15, Righetti announced in a joint statement with Hirst’s company that he will be retracting his study.
Now, the paper has been officially retracted, noting more recent measurements show formaldehyde levels to be much lower than originally reported. But most of Righetti’s co-authors disagree with the decision, the notice says: Read the rest of this entry »
In November 2015, MedChemComm issued an expression of concern (EOC) for the same paper. According to the EOC, the author of the paper, Yong Yang, flagged the paper to the journal, citing problems with authorship and portions of text overlap, which Yang attributed to an editing company.
The editor-in-chief of the journal told us Yang’s institution — China Medical University — carried out an investigation into the case at the journal’s request.
We’ve also found a 2015 retraction for Yang, after he published a paper without the okay of his previous institution in Texas.
The corresponding author of the 2016 study that found high levels of the carcinogen formaldehyde leaking from a prominent British artist’s exhibition is now retracting it.
The study, about Damien Hirst’s 2012 exhibition at the Tate Gallery in London that presented dead animals embalmed in glass cases full of formaldehyde, suggested that higher than recommended limits of the carcinogen were being released from the exhibition. The study was widely covered by the media, which raised concerns over possible health hazards to visitors.
As we reported yesterday, the journal Analytical Methods had already issued an expression of concern (EOC), noting that the corresponding author of the paper, Pier Giorgio Righetti of the Polytechnic University of Milan in Italy, warned the paper may contain unreliable data.
Today, Righetti released a joint statement with Hirst’s company, Science Ltd, stating that he will be retracting the paper (reported earlier today by the New York Times). It reads: Read the rest of this entry »
A study that found high levels of the carcinogen formaldehyde leaking from an exhibition by a prominent British artist may have unreliable data, according to its corresponding author.
The 2016 study about Damien Hirst’s exhibition at the Tate gallery in London in 2012 — which involved keeping dead animals in formaldehyde in glass cases — sparked concern in the mainstream media over the exhibition’s potential hazards to visitors.
But now the corresponding author of the paper — Pier Giorgio Righetti of the Polytechnic University of Milan in Italy — has alerted the journal, Analytical Methods, of the paper’s shortcomings. The journal has issued an expression of concern (EOC), and is investigating.
The Journal of Materials Chemistry B has issued a laundry list of corrections for a 2014 chemotherapy paper, which address re-use of “some text”, incorrectly stated doses, and miscalculations of the drug concentration, among other issues.
The paper described a new way to deliver gemcitabine via nanoparticles, focusing the drug on the tumors.
It turns out the authors’ focus wasn’t so clear when writing the paper. The researchers, at the Chinese Academy of Medical Science, Peking Union Medical College, and Tianjin University in China, said they used “some text” from two 2013 papers by a team of French oncologists “without appropriate attribution,” as well as repeatedly getting the in vivo dose wrong. The manuscript also contained several incorrect calculations of the “drug loading,” or the proportion of active drug.
Here’s the correction for “Tailor-made gemcitabine prodrug nanoparticles from well-defined drug–polymer amphiphiles prepared by controlled living radical polymerization for cancer chemotherapy” (free, but requires sign-in): Read the rest of this entry »
Last month, we reported on a 2012 paper in Interface whose authors had the journal issue an expression of concern about it because of “some of the data and methods.” At the time, The Royal Veterinary College at the University of London was conducting an investigation into the research.
“How many and which ant species are being accidentally moved around the world?,” published in 2013, has been retracted because the authors “used a wrong list of species and omitted to include a reference.”
The authors claim that this affected the magnitude of the issue, but not the overall conclusion.
The paper was written up by the press several times, including by the BBC, though according to Thomson Scientific’s Web of Knowledge, it hasn’t been cited.
