What Caught Our Attention: Cornell food marketing researcher Brian Wansink, the one-time media darling who has been dogged by mounting criticism of his findings, has lost another paper to retraction. As we’ve noted in the past, corrections for Wansink’s work tend to be long. This time, “the number of errors is too voluminous to be executed by issuing a correction statement,” according to the retraction notice for a paper about behaviors following weight loss surgery. Continue reading Caught Our Notice: Retraction eight as errors in Wansink paper are “too voluminous” for a correction
Probe finds misconduct in eight papers by researcher in Sweden
An external probe has concluded that a researcher based at the University of Gothenburg committed misconduct in multiple papers, all of which should be withdrawn.
Among 10 papers by Suchitra Sumitran-Holgersson at the University of Gothenburg, an Expert Group concluded that eight contained signs of scientific misconduct. The Expert Group, part of Sweden’s Central Ethical Review Board, also found evidence of problems within her laboratory environment.
In an email to Retraction Watch, Sumitran-Holgersson denied any “willful manipulation of data.”
According to the report (in Swedish, which we translated using Google):

“Clear signs of manipulation” in paper co-authored by prominent geneticist
A third paper co-authored by researchers based at a prominent lab whose work has been under investigation on and off for almost three years has been retracted.
According to the notice, the university’s investigation found that a 2008 paper in FEBS Letters contained “clear signs of manipulation” in three figures.
Research from geneticist David Latchman’s group has been dogged by misconduct allegations since late 2013 and subject to two investigations by the University College London (UCL). Continue reading “Clear signs of manipulation” in paper co-authored by prominent geneticist
Weekend reads: No reproducibility crisis?; greatest corrections of all time; an archaeology fraud
The week at Retraction Watch featured the retraction of a paper on homeopathy whose authors had been arrested; news about 30 retractions for an engineer in South Korea; and a story about how two stem cell researchers who left Harvard under a cloud are being recommended for roles at Italy’s NIH. Here’s what was happening elsewhere: Continue reading Weekend reads: No reproducibility crisis?; greatest corrections of all time; an archaeology fraud
Former NYU researcher falsified data in 3 papers, 7 grants: ORI
A former researcher at New York University falsified and/or fabricated data in multiple papers and grant applications, according to the U.S. Office of Research Integrity.
Bhagavathi Narayanan has already retracted three papers, the result of missing original data. Among the three papers flagged by the ORI, only one remains intact: A 2011 paper in Anticancer Research.
According to the ORI:

Delays, arguing over upcoming Cell retraction leave first author “devastated”
After being “blindsided” a few months ago when she was told one of her 2005 papers was going to be retracted, a researcher scrambled to get information about why. And when she didn’t like the answers, she took to PubPeer.
Eight days ago, Shalon (Babbitt) Ledbetter, the first author of the 2005 paper published in Cell, posted a comment on the site announcing the paper was going to be retracted after the last author’s institution, Saint Louis University (SLU), determined that some figures had been manipulated by the last author, Dorota Skowrya. A letter dated September 2, 2015 sent by SLU to Cell describes the results of the investigation — namely, that the manipulations were “cosmetic,” and had no effect on the data or the conclusions. More than two years later, Ledbetter learned the journal was planning to retract the paper, and an initial draft of the notice wouldn’t identify who was responsible; she has since been pulled into a confusing web of blame-shifting and conflicting information that has been, in her words, “heartbreaking.”
Ledbetter wrote on PubPeer:

Caught Our Notice: Voinnet co-author issues another correction
Title: What Caught Our Attention: A previous collaborator with high-profile plant biologist Olivier Voinnet (who now has eight retractions) has issued an interesting correction to a 2010 PNAS paper. Susana Rivas is last author on the paper, the correction for which notes some images were duplicated, and others were “cropped and/or stretched to match the other blots.” Rivas is currently a group leader at The Laboratory of Plant-Microbe Interactions (LIPM), “a combined INRA-CNRS Research Unit.” Continue reading Caught Our Notice: Voinnet co-author issues another correction
Why one journal will no longer accept author-suggested reviewers
In a recent editorial, the Journal of Neurochemistry declared it would no longer accept author-suggested reviewers. While other journals have done the same in order to prevent fake reviews, the Journal of Neurochemistry is basing its decision on a different logic. We spoke with editor Jörg Schulz about why he believes relying on reviewers picked by editors helps reduce bias in the peer-review process.
Retraction Watch: What prompted you to compare the outcomes of papers reviewed by experts suggested by authors versus experts selected by editors, or experts the authors “opposed?”

“The ‘1’ key was not pressed hard enough:” Did a typo kill a cancer paper?
Errors in a 2017 paper about a new cancer test may have occurred because of a simple typo while performing calculations of the tool’s effectiveness.
According to the last author, the “1” key was likely not pressed hard enough.
The error, however small, affected key values “so greatly that the conclusions of the paper can no longer be supported,” the editor said, which prompted the journal to retract the paper. Continue reading “The ‘1’ key was not pressed hard enough:” Did a typo kill a cancer paper?
Cancer biologist retracts five papers
A cancer researcher based at The Ohio State University has retracted five papers from one journal, citing concerns about figures.
The notices for all five papers state the Journal of Biological Chemistry raised questions about some figures, and the authors were not able to supply raw data in all instances. Four of the notices say the authors offered to submit data from repeat experiments and corrected figures, which the journal declined.
According to Kaoru Sakabe, data integrity manager at JBC, the authors “agreed to withdraw these articles after we declined their offers.”
