Researchers are retracting a 2016 PNASpaper that described a way to create gasoline-like fuels directly from carbon dioxide in the atmosphere.
Senior author Frederick MacDonnell, a professor at the University of Texas at Arlington (UTA), told us he originally thought his team had made a preliminary breakthrough that might “solve the world’s energy problems.” Instead, he said:
A 2011 chemistry paper required corrections so extensive that the author published the changes as a second, longer paper.
Both papers, published in the Chinese Journal of Chemistry, described the synthesis of a protein molecule with potential therapeutic applications in cancer. But when the paper’s corresponding author Yikang Wu tried to continue the work, he discovered that a substantial part of the 2011 study was incorrect.
The original paper is not marked with any editor’s note, even though the new paper — which is three pages longer than the 2011 version — acknowledges it is a “partial retraction/correction of previous results.” The new paper does appear in the list of “related content” for the 2011 article.
For the first time in its eight-year history, Nature Chemistry has retracted a paper, citing “data integrity issues.”
The 2010 paper, which explored how various iron-based molecules interact with water and ethanol, was withdrawn after the authors uncovered possible duplication in two images.
According to the retraction notice, the authors could not provide the raw data to confirm their findings and could not reproduce the figures because the experimental set-up had been dismantled. The authors subsequently requested the paper be retracted because the issues undermined “our full confidence in the integrity of the study.”
Researchers at a prominent Japanese university have retracted a 2016 paper in a chemistry journal after the first author admitted to scientific misconduct.
According to the notice, Kyushu University investigated and verified that the first author had committed scientific misconduct.
We requested a copy of the misconduct report, which revealed that the researcher, Prasenjit Mahato, a postdoctoral fellow at Kyushu University who is no longer affiliated with the university, “admitted to falsifying research” in two papers on which he was first author: a highly cited 2015 paper in Nature Materials, which was retracted in 2016, as well as the 2016 paper in Journal of the American Chemical Society (JACS), retracted earlier this month. The university investigated and confirmed misconduct in both papers.
Wecovered the Nature Materials retraction last year, but at the time, the paper’s corresponding author, Nobuo Kimizuka, only told us that the “matter has been under investigation by the formal investigation panel of our University.”
A neurochemistry journal has retracted a paper from a group in China over a duplicated image.
According to the notice, the authors used the same image in the two papers to represent different experimental conditions. The only distinguishing feature between the images: “apparent brightness changes.”
The corresponding author of a 2015 nanotechnology paper has penned a lengthy — and revealing — retraction notice, explaining why he is not certain about the findings.
In the notice, Chang Ming Li from the Institute for Clean Energy & Advanced Materials (ICEAM) at Southwest University in China, states that there is “insufficient evidence to conclusively” identify the composition of the nanowire array described in the article, which “severely undermines the validity of the reported conclusions.”
The 2015 paper has been considered “highly cited” by Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters, meaning it has received a disproportionate amount of cites given its field and publication year.
The first author of a 2013 chemistry paper is objecting to his co-authors’ decision to retract the paper, which contains duplicated figures.
We recently encountered a similar scenario with papers by first author Khalid Mahmood. In late 2015, Mahmood lost three papers in the journal ACS Applied Materials & Interfaces over duplicated images. One of the notices also indicated that the figures had “been published elsewhere and identified with different samples” — the same language used in the notice of the most recent retraction, in Journal of Materials Chemistry C.
Mahmood performed the work on the papers at Korea Advanced Institute of Science and Technology (KAIST), along with his two co-authors, Seung Bin Park and Hyung Jin Sung (also co-authors on two of the retracted papers in ACS Applied Materials & Interfaces).
A scientist has won an injunction against the University of Texas at Austin, which was deciding whether or not to revoke her PhD.
We’ve been covering the case of Suvi Orr, a chemist now based at Pfizer who earned a PhD in 2008, for a few years. During that time, UT has tried to revoke her degree twice, after the paper that made up part of her dissertation was retracted in 2012 — for allegedly containing falsified data, according to the school. The university revoked her degree in 2014, then reinstated it after she sued.
In a decision released April 20, a Texas Court of Appeals has upheld Orr’s request for an injunction against UT, preventing it from deciding whether to revoke her degree. Specifically, Orr asked that UT not be allowed to make a decision until the court has weighed in on a separate appeal, in which Orr argues the university doesn’t have the right to revoke her degree.
