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:

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particles, which would be useful in quantum computing if scientists could indeed produce and detect them, have been retracted, flagged with expressions of concern, or otherwise proven difficult to reproduce.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

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Ten of those articles, however, have been retracted this year for plagiarism, recycling his own work, and misrepresenting a reference.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

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.

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:

A gastroenterology research group led by a vice dean at a medical school has requested that a journal correct a paper with an image duplicated from an earlier study by the same group, Retraction Watch has learned. The journal has not yet determined what kind of notice to place on the article.
The group’s leader informed us of the correction request in emails asking us to remove a comment on a post from June pointing out the duplicated image. He also told us that he requested the correction before his employer received an allegation of research misconduct and started an inquiry, which found he and his group had not committed research misconduct.
Uma Sundaram, vice dean of research and graduate education at the Joan C. Edwards School of Medicine of Marshall University in Huntington, W. Va. and chair of the department of clinical and translational science, is corresponding author on both of the papers that share an image. Sundaram also has a dual appointment at a VA medical center in Huntington.

Ask teams of doctors in the neurology and rheumatology departments of the Faculdade de Medicina, Universidade de São Paulo in Brazil. They both published case reports about a patient was injured after undergoing chiropractic spinal cord manipulation. And now both journals have editor’s notes acknowledging dual publication.
The patient’s case appeared in Neurology as “Spinal Cord Injury, Vertebral Artery Dissection, and Cerebellar Strokes After Chiropractic Manipulation” and as “Breaking the diagnosis: ankylosing spondylitis evidenced by cervical fracture following spine manipulation” in the journal Internal and Emergency Medicine. The two publications included the same figure and reported many of the same details about the patient with undiagnosed ankylosing spondylitis who experienced spinal cord injury and cerebellar strokes after experiencing spinal cord manipulation.
The editors of both journals published notes flagging the cases, an expression of concern in Internal and Emergency Medicine and a “notice of dual publication” in Neurology.
The notices are nearly identical, and state, in part:

A tenure-track investigator at the National Institute of Environmental Health Sciences (NIEHS), a division of the National Institutes of Health, resigned in March, as questions mounted about her work, Retraction Watch has learned.
Jennifer Martinez has retracted at least two papers, including a 2016 Nature paper with the chair of the immunology department at St. Jude Children’s Research Hospital in Memphis, Tenn., and has another marked with an expression of concern.
The retraction is the first for Douglas R. Green of St. Jude, although he’s had a handful of corrections and two other papers he published in Nature have been questioned by scientists who couldn’t replicate the results.
After a postdoc at St. Jude, Martinez led an independent research program at NIEHS in Research Triangle Park, North Carolina since 2015, according to an online CV. She resigned from NIEHS in March and a federal research watchdog is looking into her work, a spokesperson told us:

A Johns Hopkins researcher who shared the 2019 Nobel Prize in Medicine or Physiology has retracted four papers from the Proceedings of the National Academy of Sciences (PNAS) for concerns about images in the articles.
Gregg Semenza is “one of today’s preeminent researchers on the molecular mechanisms of oxygen regulation,” the work for which he shared the 2019 Nobel, according to Hopkins. But even before that, the pseudonymous Claire Francis began pointing out potential image duplications and other manipulations in Semenza’s work on PubPeer, as described in October 2020 by Leonid Schneider.
The four papers retracted yesterday are:

On the heels of a high-profile retraction that followed deep investigations by the Science news team, Holden Thorp, the editor in chief of the journal, says it’s time to improve the process of correcting the scientific record.
In an editorial published today, Thorp, a former university provost, describes the often time-consuming and frustrating process involving journals, universities, and government agencies that are often at odds, or at least have different priorities. Based on the experience of what can feel like gridlock, he calls for breaking the process into two stages:
