Data in biofuel paper “had either been grossly misinterpreted or fabricated”

A biology journal has retracted a 2011 paper after the University of California, Los Angeles determined that the data in three figures “cannot be supported.”

In February, the journal Applied and Environmental Microbiology retracted the paper, which explores efforts to engineer bacteria to convert plant biomass into biofuel.

Claudia Modlin, assistant director of UCLA’s Office of Research Policy and Compliance, told Retraction Watch that the university informed the journal about the issues last October, after reviewing the work.

Caught Our Notice: Big journal, big correction

Title: Tranexamic Acid in Patients Undergoing Coronary-Artery Surgery

What Caught Our Attention: When the New England Journal of Medicine (NEJM) publishes a correction that is more than a misspelling of a name, we take a look. When NEJM publishes a 500-word correction to the data in a highly cited article, we take notice. This study tested the effects of a drug to prevent blood loss in patients undergoing heart surgery; it’s been the subject of correspondence between the authors and outside experts. The correction involved tweaks — lots of tweaks — to the text and tables, which did not change the outcomes.   Continue reading Caught Our Notice: Big journal, big correction

Study that said hate cuts 12 years off gay lives fails to replicate

A highly cited paper has received a major correction as a result of the ongoing battle over attitudes towards gay people, when a prominent — and polarizing — critic showed it could not be replicated.  

In December 2017, researchers led by Mark Hatzenbuehler of Columbia University corrected the paper, originally published in Social Science & Medicine in February 2014, which showed that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy. The corrigendum came more than a year after a researcher who has testified against same-sex marriage was unable to replicate the original study.

“Structural stigma and all-cause mortality in sexual minority populations,” has been cited 102 times, according to Clarivate Analytics’ Web of Science, and attracted media coverage when it was published, from outlets such as Reuters and U.S. News & World Report.

Caught Our Notice: Swiss group loses 4th paper for data manipulation

Title: Dysferlin Interacts with Histone Deacetylase 6 and Increases alpha-Tubulin Acetylation

What Caught Our Attention:  After losing three articles for data manipulation, Michael Sinnreich has retracted another paper in PLoS ONE.  All four retractions share some of the same authors, including Bilal Azakir and Sabrina Di Fulvio, who is listed as the first author on the latest retraction. None of the notices have identified a person responsible for the data manipulation. Three years ago, PubPeer user had flagged some of the figures mentioned in the notice — noting that he was “led to this paper by a story on Retraction Watch” — most likely, a 2014 post that flagged an ongoing discussion about one of Sinnreich’s papers on PubPeer.

PNAS retraction weakens theory that fish travel with siblings

In 2016, researchers at Oregon State University published a paper in PNAS that surprised the research community. They showed that certain fish species travel with their siblings — even fighting against the currents of the Pacific Ocean to stay together.

Needless to say, the research community was skeptical, given how difficult a feat this would be. And their skepticism appears to have been warranted.

Recently, the authors — led by Su Sponaugle — retracted the paper, saying a re-analysis of their data using newly developed research tools has erased their confidence in the results. According to Sponaugle, the quick reversal was thanks to the new technology and open data sharing, which led their findings to be successfully challenged within months of publication. She said her team conducted the study with the “best available knowledge we had at the time,” including what they thought were the most advanced tools available to them:

Title: Endotoxaemia during left ventricular assist device insertion: relationship between risk factors and outcome

What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct.  Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly.   Continue reading Caught Our Notice: Columbia researcher up to five retractions

Journal replaces anti-vaccine paper it retracted for missing conflicts, “number of errors”

A journal retracted a paper about how conflicts of interest might be influencing research into the link between vaccines and autism because — wait for it — the authors failed to disclose conflicts of interest.

According to the retraction notice, the editors retracted the paper without the authors’ agreement, because the authors had a host of personal and professional interests in the field they didn’t declare, such as being associated with organizations involved in autism and vaccine safety. What’s more, the article also contained “a number of errors, and mistakes of various types that raise concerns about the validity of the conclusion.”

But now, Science and Engineering Ethics has published a new version of the article that draws similar conclusions to the retracted one, albeit with an updated conflict of interest statement, among other changes. From the abstract of the revised version: Continue reading Journal replaces anti-vaccine paper it retracted for missing conflicts, “number of errors”

Researchers ask to retract cancer paper five days after it’s flagged by journal

Researchers from the University of Kansas asked to retract their paper only days after the journal issued an expression of concern related to some of the images.

The retraction notice marks the close of an episode that started in June, but it doesn’t provide much closure: Figures in the paper apparently do not match primary data, but there’s no hint as to how that happened.

In a statement sent to JCS — just five days after the expression of concern came out — last author Kristi Neufeld, a cancer biologist at KU, wrote: Continue reading Researchers ask to retract cancer paper five days after it’s flagged by journal

Title: Unravelling the influence of mild traumatic brain injury (MTBI) on cognitive-linguistic processing: A comparative group analysis

What Caught our Attention: RW readers might already be familiar with Caroline Barwood and Bruce Murdoch, two researchers from Australia who had the rare distinction of being criminally charged for research misconduct. Both Barwood and Murdoch received suspended sentences after being found guilty of multiple counts of fraud. In September 2014, University of Queensland announced that: Continue reading Caught Our Notice: Ethics, data concerns prompt another retraction for convicted researchers

Florida researcher “cherry picked” data, university investigation finds

Credit: University of Florida

A journal has retracted a 2014 paper after a university investigation found that the first author only reported certain data points that supported the paper’s conclusion.

Based on a whistleblower’s tip, the University of Florida investigated work by Huabei Jiang, a professor of biomedical engineering, and Lei Yao, a former postdoc and scientist in Jiang’s lab, for research misconduct. According to documents obtained by Retraction Watch through a  public records request, in 2015 Yao confessed to selectively choosing data in an email to the whistleblower.
