“The sampling had been compromised:” MD Anderson researchers retract cancer study

Erich Sturgis

Researchers from the University of Texas, MD Anderson Cancer Center have retracted a 2015 paper after they discovered their samples had been compromised.

Exactly how the samples were compromised, and how and when the researchers found out, remains unclear.

Originally published March 30, 2015, in Cancer, “Genome-wide association study identifies common genetic variants associated with salivary gland carcinoma and its subtypes” reported that at least three protein-coding gene variants were associated with rare salivary gland cancers. In the paper, the authors — all but one of whom are affiliated with MD Anderson — cautioned that they still needed to confirm the findings and figure out the mechanism by which the genes might increase the risk of cancer.

On Oct. 23, 2017, the researchers asked the journal to either correct or withdraw the paper. According to the retraction notice issued Jan. 9, the researchers had discovered: Continue reading “The sampling had been compromised:” MD Anderson researchers retract cancer study

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.

Two researchers with a troubled publication history about vaccine safety have withdrawn their third paper.

Along with several other co-authors, Christopher Shaw, of the University of British Columbia, and Lucija Tomljenovic, of the Neural Dynamics Research Group, recently withdrew a 2017 paper about a controversy over a tetanus vaccination program in Kenya.  

The paper has been republished in the same journal, adding another chapter to Shaw and Tomljenovic’s confusing record of publishing and withdrawing papers. The journal did not respond to our request for comment, but Shaw told Retraction Watch:

Journal retracts note of concern after court settles authorship dispute

A journal has retracted a warning posted to a paper involved in an authorship dispute, after the issue was resolved in a court case.

In an editorial published Jan. 10, editors at the journal Molecules wrote that they were removing the expression of concern for “Helleborus purpurascens—Amino Acid and Peptide Analysis Linked to the Chemical and Antiproliferative Properties of the Extracted Compounds.”

The editors flagged the 2015 paper in June, 2016 after a researcher in Germany also claimed authorship. In the 2016 notice, the editors wrote:

Second paper tied to drug scandal in Norway ski team retracted

Researchers in Norway have retracted a second high-profile exercise paper — again after running afoul of an ethical approval committee.

As part of the 2016 study, the researchers gave athletes asthma medication to measure its effect on signals from the nervous system to the lungs; although the drug appeared to have no detectable effect on the nervous system signals, 45 minutes after getting the drug, athletes (including those without asthma) showed an average slight increase in one measure of lung function.

Annette Birkeland, of The Norwegian National Research Ethics Committees (FEK), told us:

Judge orders journal to identify peer reviewers: CrossFit lawyer

A court is reportedly telling a journal to unmask a retracted paper’s peer reviewers, part of a defamation lawsuit involving the journal’s publisher and the CrossFit exercise brand.

According to an attorney representing CrossFit, yesterday Judge Joel Wohlfeil of the San Diego Superior Court decided that the National Strength and Conditioning Association (NSCA) must turn over to CrossFit the names of peer reviewers of “Crossfit-based high-intensity power training improves maximal aerobic fitness and body composition,” by Jan. 26. The names will be revealed under a protective order, the lawyer said, meaning CrossFit and the other defendants will see them but cannot disclose them to others.

CrossFit asks court to unmask peer reviewers of retracted study

Another front has opened up in the legal battle between the CrossFit exercise brand and a competitor, spurred by a now-retracted paper about the risk of injury from the workout program. Soon, a judge will decide whether CrossFit is entitled to learn the names of the study’s peer reviewers.

CrossFit has tried and failed to identify them before. If they’re successful now, it could help establish a new way to legally breach reviewer confidentiality; two outside lawyers we consulted said they’d never before seen a court order a journal to reveal an article’s peer reviewers.

On Jan. 18, Judge Joel Wohlfeil of the Superior Court of the State of California in San Diego is scheduled to hold a hearing on whether or not the National Strength and Conditioning Association (NSCA) should be compelled to unmask the reviewers for “Crossfit-based high-intensity power training improves maximal aerobic fitness and body composition.”

The article was published in 2013 in the Journal of Strength and Conditioning Research (JSCR), the official research publication of the NSCA, and was retracted last year. It’s referred to as the “Devor article” in the court documents, after last author Steven Devor, a former professor at The Ohio State University (OSU).

A “discovery referee” assigned to the defamation case recently ordered NSCA to provide CrossFit with the reviewers’ names, but NSCA is challenging those rulings, saying that they have the same right to protect their sources as journalists do.

Authors retract paper on psychopathic traits in bosses

A paper on the prevalence of cruel social behavior in the corporate world has been retracted, following an investigation at the authors’ university. According to the senior author, she inadvertently paraphrased a dissertation on the same topic that did not belong to her student and co-author.

On Sept. 21, 2016, Katarina Fritzon, a professor at Australia’s Bond University, and Nathan Brooks, who was Fritzon’s graduate student at the time, published “Psychopathic personality characteristics amongst high functioning populations,” in Crime Psychology Review. The paper suggested that as many as one in five corporate executives exhibited the hallmarks of a psychopath, such as lack of remorse or egocentricity.

Fritzon told Retraction Watch the paper drew largely from the introduction to Brooks’s doctoral dissertation. Along with Brooks’ research, it received media attention worldwide. But Fritzon told us that in October 2016 she received a complaint from another university about the work: Continue reading Authors retract paper on psychopathic traits in bosses

Journal retracts “hopelessly flawed” paper linking cell phone radiation to pain

A journal is retracting a paper linking radio waves from cell phone towers to pain in amputees, despite objections from the authors.

“Anthropogenic Radio-Frequency Electromagnetic Fields Elicit Neuropathic Pain in an Amputation Model,” originally published Jan. 16, 2016 in PLOS ONE, suggested that rats with injured nerves experienced pain when exposed to the type of electromagnetic radiation emitted by cell phone network towers. A press release issued by the University of Texas at Dallas (UT-Dallas) — where the corresponding author Mario Romero-Ortega and two co-first authors are based — said that this phenomenon has been reported anecdotally by people missing limbs.

But the study, especially its methodology, met with immediate criticism in the article’s comment section. PLOS ONE noted in March 2016 that the authors had contacted the journal regarding an error in some of the exposure levels reported in the study, which journal staff were “looking into.” In December 2016, the journal told the authors it was going to retract the paper. Now, more than one year later, it finally has.

Ken Foster, a professor at the University of Pennsylvania who commented in February 2016 that the paper was “hopelessly flawed,” told us: Continue reading Journal retracts “hopelessly flawed” paper linking cell phone radiation to pain

They thought they might solve the world’s energy problems. Then they realized they were wrong.

Frederick MacDonnell

Researchers are retracting a 2016 PNAS paper that described a way to create gasoline-like fuels directly from carbon dioxide in the atmosphere.

Senior author Frederick MacDonnell, a professor at the University of Texas at Arlington (UTA), told us he originally thought his team had made a preliminary breakthrough that might “solve the world’s energy problems.” Instead, he said:

It was an elaborate trap we fell into.

In a retraction notice that contains more information than we usually see, MacDonnell and his co-authors wrote: Continue reading They thought they might solve the world’s energy problems. Then they realized they were wrong.
