Contamination leads to swift retraction for Science paper on the origins of Omicron in Africa

The authors of a paper that proposed the Omicron variant of SARS-Cov-2 had evolved in Western Africa months before it was first detected in South Africa have retracted their study after discovering contamination in their samples, as several scientists had suggested on Twitter was the case.

The article, “Gradual emergence followed by exponential spread of the SARS-CoV-2 Omicron variant in Africa,” was published in Science on December 1 by a team led by Jan Felix Drexler of Charité – Universitätsmedizin Berlin.

Soon after publication, many geneticists expressed skepticism on social media about the study, including questioning whether the results came from contamination during the sequencing process.

Tulio de Oliveira, director of the Centre for Epidemic Response and Innovation and the KwaZulu-Natal Research Innovation and Sequencing Platform at the University of KwaZulu-Natal in South Africa, tweeted on December 4 about “weaknesses” in the study, including that “the quality of the sequences seems problematic”:

PLOS flags nearly 50 papers by controversial French COVID researcher for ethics concerns

The publisher PLOS is marking nearly 50 articles by Didier Raoult, the French scientist who became controversial for promoting hydroxychloroquine for treating COVID-19, with expressions of concern while it investigates potential research ethics violations in the work.

PLOS has been looking into more than 100 articles by Raoult, but determined that the issues in 49 of the papers, including reuse of ethics approval reference numbers, warrant expressions of concern while the publisher continues its inquiry.

In August of 2021, scientific sleuth Elisabeth Bik wrote on her blog about a series of 17 articles from IHU-Méditerranée Infection that described different studies involving homeless people in Marseille over a decade, but all listed the same institutional ethics approval number. One of those papers, “Distinguishing Body Lice from Head Lice by Multiplex Real-Time PCR Analysis of the Phum_PHUM540560 Gene,” about which Bik also posted on PubPeer, was published in PLOS ONE in 2013, and is receiving an expression of concern today.

Board members decry their own journal’s retraction of paper on predatory publishers

Academics affiliated with a journal that retracted a paper on predatory publishing last year — after one of the publishers mentioned in the analysis complained — have put out a letter critiquing the decision, saying the retraction “lacks justification.”

The authors of the retracted article appealed the decision to the Committee on Publication Ethics (COPE), but lost. They republished their work in another journal last month.

As we reported last September, the Springer Nature journal Scientometrics retracted “Predatory publishing in Scopus: evidence on cross-country differences,” after receiving a letter from Fred Fenter, chief executive editor of Frontiers, one of the publishers included in the analysis, demanding the paper’s “swift retraction.” His key complaint: the article’s reliance on librarian Jeffrey Beall’s now-defunct list of allegedly predatory publishers.

Buzzy Lancet long COVID paper under investigation for ‘data errors’

An early and influential paper on long COVID that appeared in The Lancet has been flagged with an expression of concern while the journal investigates “data errors” brought to light by a reader.

An editorial that accompanied the paper when it was published in January of last year described it as “the first large cohort study with 6-months’ follow-up” of people hospitalized with COVID-19. The article has received plenty of attention since then.

Titled “6-month consequences of COVID-19 in patients discharged from hospital: a cohort study,” the paper has been cited nearly 1,600 times, according to Clarivate’s Web of Science. Altmetric finds references to it in multiple documents from the World Health Organization.

‘Liberals lecture, conservatives communicate’ paper gets lengthy expression of concern

An article from 2019 that caught some media buzz – including from the New York Times – for its analysis of political speeches now bears an expression of concern that’s almost as long as the original paper.

In “Liberals lecture, conservatives communicate: Analyzing complexity and ideology in 381,609 political speeches,” published in PLOS ONE, the authors concluded that “speakers from culturally liberal parties use more complex language than speakers from culturally conservative parties,” as they stated in their abstract.

But after reading the article, linguist Joe McVeigh, a university teacher at the University of Jyväskylä in Finland, wrote an online comment on the article detailing “several fundamental and critical flaws in its methodology.” A key issue: applying the Flesh-Kincaid test, which was developed for assessing the readability of a written text, to political speeches. As McVeigh told us:

Science paper on sense of taste gets expression of concern as university investigates

Science has published an expression of concern for a recent article on a receptor for bitter taste while the authors’ institution investigates “potential discrepancies” with a figure.

The article, “Structural basis for strychnine activation of human bitter taste receptor TAS2R46,” was published in September of this year.

According to the abstract:

Another ‘Majorana’ particle paper retracted, this time from Science

Nearly a year after marking a paper on the elusive “Majorana” particle with an expression of concern, and almost three years after publishing a critique of its reproducibility, Science has retracted the article due to “serious irregularities and discrepancies” in the data.

A few papers about Majorana particles, which would be useful in quantum computing if scientists could indeed produce and detect them, have been retracted, flagged with expressions of concern, or otherwise proven difficult to reproduce.

The latest article to be retracted, “Chiral Majorana fermion modes in a quantum anomalous Hall insula- tor–superconductor structure,” has been cited more than 400 times since it was published in 2017, according to Clarivate’s Web of Science. About 10 percent of those citations have come since Science’s editors published their expression of concern last December.

The retraction notice states:

BMJ says it’s “an ongoing effort” to find articles by plagiarizing concussion researcher Paul McCrory

Weeks after the British Medical Journal corrected a press release about nine retractions and dozens of expressions of concern to mark articles by a prominent concussion expert, a spokesperson for the journal told us it’s still “an ongoing effort” to identify all the articles on which the expert is the sole author.

The concussion researcher, Paul McCrory, was editor in chief of the British Journal of Sports Medicine, published by the BMJ, from 2001-2008, and published many editorials on which he was the only listed author. McCrory also chaired the influential Concussion in Sport Group, was involved in drafting consensus statements on concussion in sports, and consulted with leagues.

Ten of those articles, however, have been retracted this year for plagiarism, recycling his own work, and misrepresenting a reference.

In comments to us, his only public statements to date about the matter, McCrory acknowledged some of the plagiarism as unintentional “errors,” and offered “my sincere and humble apologies.” He no longer chairs the Concussion in Sport Group, and the Australian Football League has critically reviewed his work for the league, the Guardian Australia reported.

Former medical school dean earns sixth retraction

A kidney researcher and former dean of a medical school has now had six papers retracted and one marked with an expression of concern in a little more than a year.

The latest retraction for Joseph I. Shapiro, of a 2015 paper in Science Advances, comes two years after PubPeer commenters began posting about potentially duplicated images in the article, and one year after the authors corrected two of its figures.

Shapiro, the corresponding author on the article, stepped down as dean of the Joan C. Edwards School of Medicine at Marshall University in Huntington, W. Va., on June 30th of this year, but remains a tenured professor at the institution. Neither he nor Komal Sodhi, the first author on the article and also of Marshall, have responded to our request for comment.

Retractions of work Shapiro led began last September, according to our database, following critical comments on PubPeer.

Paper by gene therapy Zolgensma developer retracted because of discrepancies in mouse survival rates

A paper describing preclinical work that was foundational for the gene therapy for spinal muscular atrophy now sold as Zolgensma has been retracted for data inaccuracies.

The article, “Rescue of the spinal muscular atrophy phenotype in a mouse model by early postnatal delivery of SMN,” was published in Nature Biotechnology in 2010. Its corresponding author, Brian Kaspar, was at The Ohio State University at the time. Kaspar went on to become the scientific founder and chief scientific officer of AveXis, which created Zolgensma and was acquired by Novartis in 2018 for $8.7 billion.

The paper has been cited 557 times, according to Clarivate’s Web of Science, and referenced in at least 59 patents, according to Altmetric.

According to the retraction notice, the authors contacted the journal last year about “inaccuracies” in the data. After the journal’s investigation, the editors decided to retract the article over the author’s objections. The notice explained:
