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.

Here’s the EOC, issued this week: Continue reading Study warning of toxic leaks from Damien Hirst’s work may not be reliable, says author

1st retraction for cancer researcher who doctored data in 11 studies

LeukemiaA cancer journal has retracted a paper co-authored by a researcher who falsified or fabricated data in 11 studies, according to an investigation by the Office of Research Integrity (ORI).

In December 2015, an ORI probe into the work of Girija Dasmahapatra concluded that he had

…duplicated, reused, and/or relabeled Western blot panels and mouse images and claimed they represented different controls and/or experimental results…

Dasmahapatra left the Virginia Commonwealth University (VCU) in July 2015.

Here’s the retraction notice, issued in April 2016: Continue reading 1st retraction for cancer researcher who doctored data in 11 studies

Harvard researcher’s PhD revoked, former group earns three more retractions

Journal of Biological ChemistryA research fellow at Harvard has lost his PhD from a university in Singapore after being found guilty of falsifying data, and his former group leader’s contract has been terminated by his institution.

But that’s not the whole story. This tangled mess involves not only the Harvard researcher, Sudarsanareddy Lokireddy, and his former boss, Ravi Kambadur at the Nanyang Technological University (NTU) in Singapore, but an as-yet unnamed colleague of theirs who, we’re told, has admitted making up data in three papers, on which Lokireddy and Kambadur are co-authors. Bear with us as we walk you through this tale.

Two of those papers have been retracted by The Journal of Biological Chemistry (JBC); one in Molecular Endocrinology has yet to be pulled. Kambadur, who held joint appointments at the NTU and the Agency for Science, Research and Technology (A*STAR) in Singapore, has now had his contract terminated at both institutions.  Continue reading Harvard researcher’s PhD revoked, former group earns three more retractions

Researcher who sued to stop retractions earns his 7th

A diabetes researcher who sued to stop a publisher from retracting his papers has just received his seventh retraction.

The latest retraction for Mario Saad, who is based at the University of Campinas (Unicamp) in São Paulo, Brazil, is for a PLOS ONE paper (which was altered last year by a mega-correction). Although an institutional investigation found no evidence of research misconduct, the notice states:

the preparation of the figures falls below the standard of publication and therefore the authors and the editors have agreed that the correct action is to retract the article. 

Saad previously sued the American Diabetes Association (ADA) to remove expressions of concern from four of his papers published in the organisation’s flagship journal, Diabetes. However, all four of the papers were later retracted after the suit was dismissed in 2015.

Here’s the new retraction notice, issued July 8: Continue reading Researcher who sued to stop retractions earns his 7th

“We should err on the side of protecting people’s reputation:” Management journal changes policy to avoid fraud

How can academic journals ensure the integrity of the data they publish? For one journal, the key is looking deeply at statistics, which revealed crucial problems in the research of recent high-profile fraudsters such as Anil Potti. Editor-in-chief of the Journal of Management, Patrick Wright from the University of South Carolina, recently authored an editorial about how he’s taken those lessons to heart — and why he believes retractions don’t always hurt a journal’s reputation. 

RW: Can you take us through the changes in the editorial policy of your journal? Continue reading “We should err on the side of protecting people’s reputation:” Management journal changes policy to avoid fraud

Second retraction for researcher who faked 70+ experiments

Journal of Biological ChemistryTwo researchers found to have faked data by the U.S. Office of Research Integrity (ORI) have lost a paper that they co-authored.

According to the ORI report issued on May 25, Ricky Malhotra, one of the researchers in question, admitted to fabricating 74 experiments, and falsifying well over 100 Western blots while at the Universities of Michigan (UM) and Chicago (UC). One week later, the ORI issued additional findings about Karen D’Souza, a colleague of Malhotra’s at the UC, concluding that she had also falsified some data.

Both researchers agreed to the retraction of a 2010 paper published in The Journal of Biological Chemistry (JBC), the reports note.

Here’s the retraction notice, issued on July 1: Continue reading Second retraction for researcher who faked 70+ experiments

Is the bulk of fMRI data questionable?

Last week, a study brought into question years of research conducted using the neuroimaging technique functional magnetic resonance imaging (fMRI). The new paper, published in PNAS, particularly raised eyebrows for suggesting that the rates of false positives in studies using fMRI could be up to 70%, which may affect many of the approximately 40,000 studies in academic literature that have so far used the technique. We spoke to the Anders Eklund, from Linköping University in Sweden, who was the first author of the study. Continue reading Is the bulk of fMRI data questionable?

Authors retract study that found pollution near fracking sites

Environmental Science and TechnologyThe authors of two environmental papers, including one about the effects of fracking on human health, have retracted them after discovering crucial mistakes.

One of the studies reported an increased level of air pollution near gas extraction sites, and the other suggested that 2010’s Deepwater Horizon oil spill in the Gulf of Mexico contributed to air contamination.

According to the corresponding author of both papers, Kim Anderson at Oregon State University, the journal plans to publish new versions of both papers in the next few days. In the case of the fracking paper, the conclusions have been reversed — the original paper stated pollution levels exceeded limits set by the U.S. Environmental Protection Agency (EPA) for lifetime cancer risk, but the corrected data set the risks below EPA levels.

The fracking paper received some media attention when it was released, as it tapped into long-standing concerns about the environmental dangers of hydraulic fracturing (fracking), which extracts natural gas from the earth. A press release that accompanied the paper quoted Anderson as warning: Continue reading Authors retract study that found pollution near fracking sites

Authors who lost paper linking fecal transplants to obesity have another retracted

International Journal of ObesityAn obesity journal has retracted a study by authors who previously lost another paper that suggested a link between the fecal microbiome and obesity.

We first came across on the now-retracted paper in the International Journal of Obesity (IJO) in April when we reported on the authors’ other retraction in Diabetes. The 2014 paper had a corrigendum, published the same year, and also for image-related issues. Since then, however, the journal has pulled the IJO paper and its associated corrigendum at the request of the French National Institute of Agronomic Research (INRA) in Paris.
