Last summer, a journal retracted another paper by the pair, also citing suspicions of image manipulation. The latest batch of retractions — issued by seven different journals — includes some papers that have been questioned on PubPeer.
Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).
We’ll start with the papers they share: Read the rest of this entry »
Two journals have retracted two papers by the same group within months of each other, after editors were independently tipped off that they contained duplicated figures representing different experiments.
The two papers were published by PLOS ONE and The Egyptian Journal of Biochemistry and Molecular Biology (EJBMB) in 2015 and 2014, respectively. According to the PLOS ONE paper’s corresponding author, last author Saad A. Noeman from Tanta University in Egypt used the same Figure 1 in both papers, along with another 2013 paper in EJBMB.
Corresponding author Yasser S. El-Sayed, head of the Department of Forensic Medicine and Toxicology at Damanhour University in Egypt, told us he learned of this issue after a reader brought the figure manipulation and duplication concerns to PLOS ONE’s attention.
El-Sayed said that he tried to figure out what had happened.
Researchers in China have retracted a paper and corrected three others in a plant journal, citing problems with multiple figures.
Lixin Zhang, from the Chinese Academy of Sciences in Beijing, is corresponding author on all four papers, published by Plant Physiology. We’ve reported on three retractions and two corrections from Lixin Zhang and some of the same co-authors, bringing Zhang’s total to five retractions and four corrections, by our count.
According to the retraction notice, the authors agreed to pull the article because of figure-related “irregularities and inappropriate data handling” — but despite these issues, they remain confident that their conclusions are still valid.
Here’s the latest retraction notice, issued this February, for “Cooperation of LPA3 and LPA2 Is Essential for Photosystem II Assembly in Arabidopsis:” Read the rest of this entry »
A group of researchers in France has been forced to retract their 2002 article in the Journal of Virology after learning that the paper was marred by multiple image problems.
The paper, “P0 of Beet Western Yellows Virus Is a Suppressor of Posttranscriptional Gene Silencing,” came from the lab of Veronique Ziegler-Graff, a plant biologist at the University Louis Pasteur, in Strasbourg. The authors attribute some of the image problems to “genuine mounting mistakes,” and have repeated the experiments to confirm the conclusion, as have other labs. However, the researchers couldn’t find all the original data from the 2002 paper.
Although the retraction statement points the finger at the first author, Sebastien Pfeffer, the list of contributors includes , a frequent collaborator of Olivier Voinnet, a high-profile plant biologist whose work has come under intense scrutiny.
One paper published in 2012 was retracted — at the researcher’s request — for copying from a 2010 paper of his. In turn, both papers were duplicated in a paper that was published in 2016, and retracted a few months later. That 2016 paper borrowed from another paper published last year, which was quickly retracted after we contacted the journal.
These papers — by Dilip Kumar Das, listed at T. M. Bhagalpur University in India — were flagged in March by a PubPeer commenter.
In December, Plant Cell, Tissue and Organ Culture (PCTOC) retracted Das’s 2012 paper; here’s the retraction notice:
Gearóid Ó Faoleán, ethics and integrity manager at Frontiers, which publishes Frontiers in Plant Science, told us:
In accordance with our complaints protocol, the Field Chief Editor led the investigation that resulted in the decision to retract the paper.
According to the EOC notice in New Phytologist, two figures in the paper contained “some anomalies,” and the corresponding author has acknowledged that there are problems with the images.
According to the new retraction notice in The Plant Cell, some figures in the paper were manipulated, as well as “inappropriately duplicated and reused from a previous publication.” The authors assert that they believe the conclusions remain valid.
The journal has also issued two corrections that include some of the same authors — including one that cites inappropriate image manipulation.
A high-profile plant scientist who has been racking up corrections and retractions at a steady clip has had another paper — this one from Science — retracted.
The retraction, of a paper that had been previously corrected, is the eighth for Olivier Voinnet. According to the notice, the correction did not address all the figure problems with the paper, which “cannot be considered the result of mistakes.”
A few months ago, an author alerted us to two retractions — including one in PNAS — after realizing his team had been using plants affected by inadvertent genotyping errors for an entire year. He initially told us these were the only two papers affected, but more recently reached out to say he had to pull a follow-up article, as well.
Recently, Steven C. Huber contacted us about the newest retraction, noting he was submitting a notice to the editor of Plant Signaling and Behavior:
