One set of 10 articles recognized by Dr. David confirmed repeated reuse of similar or overlapping black-and-white photographs of most cancers cells supposedly below completely different experimental circumstances, he stated.
“There’s no motive to have carried out that until you weren’t doing the work,” Dr. David stated.
A type of papers, printed in 2012, was formally tagged with corrections. In contrast to later research, which have been largely overseen by Dr. Yoon in New York, this paper was written by South Korea-based scientists, together with Changhwan Yoon, who then labored in Seoul.
An immunologist in Norway randomly chosen the paper as a part of a screening of copied information in most cancers journals. That led the paper’s writer, the medical journal Oncogene, to add corrections in 2016.
However the journal didn’t catch all the duplicated information, Dr. David stated. And, he stated, photographs from the examine later turned up in similar type in one other paper that is still uncorrected.
Copied most cancers information saved recurring, Dr. David stated. An image of a small crimson tumor from a 2017 examine reappeared in papers in 2020 and 2021 below completely different descriptions, he stated. A ruler included within the footage for scale wound up in two completely different positions.
The 2020 examine included one other tumor picture that Dr. David stated seemed to be a mirror picture of 1 beforehand printed by Dr. Yoon’s lab. And the 2021 examine featured a colour model of a tumor that had appeared in an earlier paper atop a special part of ruler, Dr. David stated.
“That is one other instance the place this appears to be like deliberately carried out,” Dr. Bik stated.
The researchers have been confronted with extra critical motion when the writer Elsevier withdrew the abdomen most cancers examine that had been printed on-line in 2021. “The editors decided that the article violated journal publishing ethics tips,” Elsevier stated.
Roland Herzog, the editor of Molecular Remedy, the journal the place the article appeared, stated that “picture duplications have been observed” as a part of a means of screening for discrepancies that the journal has since continued to beef up.
As a result of the issues have been detected earlier than the examine was ever printed within the print journal, Elsevier’s coverage dictated that the article be taken down and no clarification posted on-line.
However that call appeared to battle with business tips from the Committee on Publication Ethics. Posting articles on-line “normally constitutes publication,” these tips state. And when publishers pull such articles, the rules say, they need to preserve the work on-line for the sake of transparency and publish “a transparent discover of retraction.”
Dr. Herzog stated he personally hoped that such an evidence may nonetheless be posted for the abdomen most cancers examine. The journal editors and Elsevier, he stated, are inspecting potential choices.
The editors notified Dr. Yoon and Changhwan Yoon of the article’s removing, however neither scientist alerted Memorial Sloan Kettering, the hospital stated. Columbia didn’t say whether or not it had been informed.
