“Riddled with errors”: Study of cell phones and breast cancer retracted

A journal has retracted a study that said exposure to radiofrequency radiation increased the risk of breast cancer after an epidemiologist found that some of the papers it relied upon did not measure radiofrequency radiation at all, in a decision that the lead author has called “unfair.”

The study, titled “Exposure to radiofrequency radiation increases the risk of breast cancer: A systematic review and meta‑analysis,” was published in Experimental and Therapeutic Medicine on November 9th. The paper analyzed eight prior studies — four case‑control and four cohort studies — concluding “that radiofrequency radiation exposure significantly increased the risk of breast cancer, especially in women aged ≥50 years and in individuals who used electric appliances, such as mobile phones and computers.”

In early December, Frank de Vocht, an epidemiologist at the University of Bristol, decided to investigate the study. He explained in an email to Retraction Watch:

University clears scientist of logging industry’s misconduct allegations

The University of Tasmania has cleared one of its scientists of wrongdoing after she was accused by the Australian logging industry of publishing flawed research linking logging to increased forest flammability and of having a conflict of interest with an environmental group.

The university then implemented mandatory research integrity training for its school of geography, which Jennifer Sanger, the researcher who worked in that school, suggests is due to the university’s “very strong ties with the forestry industry.”

In May 2020, Sanger published a study titled, “Propensities of Old Growth, Mature and Regrowth Wet Eucalypt Forest, and Eucalyptus Nitens Plantation, to Burn during Wildfire and Suffer Fire-Induced Crown Death,” in the journal Fire. The study found that logged forests were generally more flammable than those left unlogged, a finding that has been upheld in recent research.

On August 13, Sanger requested that Fire pull the study, according to Alistair Smith, the journal’s editor-in-chief. Sanger asked for a retraction after a reader went through the study’s dataset and found issues with its analysis, she explained in an email:

After grad student suicide, misconduct findings, university suspends professor

Nearly two years after a doctoral student hanged himself in a building on the campus of the University of Florida, in Gainesville, his supervisor has been placed on paid leave, a move that follows a report released last month that found evidence of misconduct at three different computing conferences.

Huixiang Chen was found dead in June 2019, while working in the research group of Tao Li, a computing engineer. A few months before his suicide, Chen wrote a paper for a prestigious, annual conference in computing, the International Symposium on Computer Architecture, or ISCA, which is one of the three mentioned in the report.

Chen’s paper was accepted, but his death, before the conference began, sparked allegations that the peer-review process had been unfairly compromised and that Li had coerced his student to publish faulty results. The University of Florida launched an investigation into the circumstances of Chen’s death shortly after his suicide, but those findings have not been publicly released.

Li did not respond to requests for comment. The report on the conferences, released February 8 by a “joint investigative committee” from two organizations that sponsored the ISCA meeting, reached four main conclusions, starting with:

Bad blood at a lab leads to retraction after postdoc publishes study without supervisor’s permission

A former postdoc at Stony Brook University who was moonlighting in a different lab has lost a study after a university investigation found issues with the work, including “overlap” with prior grants and an earlier study that her supervisor had published, as well as misreported data.

The supervisor — neuroscientist Joshua Plotkin, who was the complainant in the investigation — said that the study was published without his permission, according to an email seen by Retraction Watch. The former postdoc, Catarina Cunha, has denied wrongdoing and called the investigation a “witch hunt,” claiming that the university ignored her exculpatory evidence and that the paper’s findings are valid and original.

University of Tennessee investigation finds manipulated images in Science paper

An investigation by the University of Tennessee Health Sciences Center, in Memphis, into a 2006 Science paper found evidence that three figures in the article had been manipulated.

Science sleuth Elisabeth Bik first flagged the paper, titled “Molecular Linkage Between the Kinase ATM and NF-κB Signaling in Response to Genotoxic Stimuli,” to the editors of Science in 2015. Today, Science issued an expression of concern for the paper:

Meet the postdoc who says he’s been trying to retract his own paper since 2016

In August 2015, bioengineers gathered in Milan, Italy, for the 37th annual conference of the IEEE Engineering in Medicine and Biology Society. About 2,000 papers were accepted and published online for the conference. But an author of one of those articles says he’s been trying to retract it since 2016.

As a PhD student at the Université de Lorraine, in France, Khuram Faraz worked with professors Christian Daul and Walter Blondel on the processing of biomedical images, mainly for dermatology. Faraz is listed as a co-author on a paper titled “Optical flow with structure information for epithelial image mosaicing,” which was published at the 2015 conference. The paper has been cited twice, according to Clarivate Analytics’ Web of Science.

A few months after the conference, in January 2016, Faraz emailed Daul and Blondel about his concerns with the study, according to emails that Faraz shared on PubPeer last June. Faraz allegedly told Daul and Blondel that, for a specific method used in the paper, called RFLOW:

Eleven papers corrected after nutrition prof fails to disclose patent, company ties

Eight journals have corrected a total of eleven papers after one of the authors failed to list potential financial conflicts of interest. Two additional journals have also told Retraction Watch that they plan to issue corrections, which will bring the total to 13 or more.

Stuart Phillips is a professor and director of the Centre for Nutrition, Exercise, and Health Research at McMaster University in Hamilton, Ontario. The corrected studies — which now reflect Phillips’ links to companies or patents — are all related to his research on nutritional supplements and exercise.

One journal, Medicine & Science in Sports & Exercise, issued a single correction for four studies authored by Phillips:

Leading evidence-based group blames pandemic for 9-month delay pulling flawed cancer review

Last February, Richard Pollock was reading a review in the Cochrane Database of Systematic Reviews — a prominent resource for evidence-based medicine — when he spotted an error.

In the first figure, which compared the effectiveness of two different treatments for the most common form of liver cancer, a label was switched. The error made it seem like the “worse” treatment was better than the more effective option.

Pollock, a health economist, was concerned enough to send an email to Omar Abdel-Rahman, the corresponding author, on February 20th. Abdel-Rahman, an oncologist at the University of Alberta, wrote back the next day, saying he would review the comments with experts at Cochrane, “and if there is any typos in the publication, it will be corrected immediately.” Emails seen by Retraction Watch show that, when replying to this email, Abdel-Rahman copied one of Cochrane’s editors, Dimitrinka Nikolova.

Months passed. Pollock sent another email to Abdel-Rahman and two Cochrane editors — Nikolova and Christian Gluud — on June 15th. Then, on November 16th, the journal pulled the review with a brief notice:

Mathematician ranked as Clarivate “highly cited researcher” has third paper retracted

A math professor named as a “highly cited researcher” by Clarivate Analytics has had his third paper retracted after issues with it were flagged last year.

The mathematician, Abdon Atangana, is a professor at The University of the Free State, in Bloemfontein, South Africa, and China Medical University, Taiwan.

Atangana’s article, “Derivative with two fractional orders: A new avenue of investigation toward revolution in fractional calculus,” was published in The European Physical Journal Plus — where Atangana is an editor — on Oct. 24, 2016, and has been cited 37 times, according to Clarivate Analytics’ Web of Science.

Journal pulls two studies that listed an author without his permission

David Cox

Springer Nature has removed two studies that were published in its journal Cluster Computing and included a co-author who didn’t know that the papers existed until December 2020, years after they were published.

The move follows reporting by Retraction Watch last week about the papers, which listed David Cox, the IBM Director of the MIT-IBM Watson AI Lab, as a co-author.

The studies–“A FCM cluster: cloud networking model for intelligent transportation in the city of Macau,” and “Mobile network intrusion detection for IoT system based on transfer learning algorithm,” disappeared from the publisher’s website on January 29th, without any retraction notices.

A spokesperson for Springer Nature told Retraction Watch:
