Science has retracted two papers by Frank Sauer, of the University of California, Riverside, after the university found evidence of serious image manipulation.
Here’s the notice, signed by Science editor-in-chief Marcia McNutt: Continue reading Science retracts two papers for image manipulation
We’ve been following the case of Amine Bahi, a neuroscience researcher in the United Arab Emirates who has managed something unusual in the annals of Retraction Watch: Three different retractions for three completely different reasons. One was for “legal issues,” another was for lack of IRB approval, and the third was for using RNAs from the wrong species.
Now, Bahi’s co-authors have repeated the last of those studies with the right RNAs, and have republished their paper in the same journal, Biological Psychiatry — but without Bahi.
The retraction notice for “Blockade of Protein Phosphatase 2B Activity in the Amygdala Increases Anxiety- and Depression-Like Behaviors in Mice” now includes this final paragraph: Continue reading Researchers repeat retracted study, republish in same journal sans first author
A former Harvard postdoc who was found guilty of faking data at Oxford as a student did the same thing at Harvard, according to the Office of Research Integrity (ORI).
We first wrote about Helen Freeman in February, when we covered a retraction in Cell Metabolism that said the UK’s Medical Research Council had found that she committed misconduct while working as a student at Oxford. Today, a Federal Register notice from the ORI reports that Freeman faked images in a manuscript submitted to Nature while she was working on federally funded grants at Harvard Medical School and Beth Israel Deaconess Medical Center.
From the ORI’s report: Continue reading Serial fakery: Researcher found to have committed misconduct at Harvard and Oxford
Cory Toth, the University of Calgary diabetes researcher who told us last month he would stop publishing in science following a string of inappropriate manipulations, has retracted another paper.
Here’s the notice in Brain for “Intranasal insulin prevents cognitive decline, cerebral atrophy and white matter changes in murine type I diabetic encephalopathy:” Continue reading Diabetes researcher who says he will no longer publish now up to five retractions
The International Journal of Biochemistry & Cell Biology has retracted a 2013 paper by a group from China after learning that only the first author knew about the article.
The paper was titled “Construction of circular miRNA sponges targeting miR-21 or miR-221 and demonstration of their excellent anticancer effects on malignant melanoma cells,” and it was led by Yuchen Liu. Liu’s affiliations include the Institute of Dermatology and Department of Dermatology at No. 1 Hospital, part of Anhui Medical University, and the State Key Laboratory Incubation Base of Dermatology for the Ministry of National Science and Technology.
Here’s the retraction notice:

A group of researchers from France has retracted a 2013 paper from Molecular Cell after realizing that their analyses of microscopy images were flawed.
Here’s the notice for “RecA-Promoted, RecFOR-Independent Progressive Disassembly of Replisomes Stalled by Helicase Inactivation:” Continue reading Sampling error, flawed analysis, and miscalculation trigger Molecular Cell retraction
Shigeaki Kato, who resigned from the University of Tokyo in 2012 after being found to have inappropriately manipulated dozens of images, has two more retractions, both in Molecular Cell.
Here’s the notice for 2002’s “Nuclear Receptor Function Requires a TFTC-Type Histone Acetyl Transferase Complex:” Continue reading Shigeaki Kato up to 25 retractions
In December, we reported on the case of Timothy Sheehy, a former government contractor who was found to have faked results. ORI found that Sheehy
fabricated the quantitative and qualitative data for RNA and DNA purportedly extracted from 900 formalin-fixed, paraffin-embedded (FFPE) colorectal tissue samples presented in Table 1 of the CEBP paper and falsely reported successful methodology to simultaneously recover nucleic acids from FFPE tissue specimens, when neither the extractions nor analyses of the FFPE samples were done. Thus, the main conclusions of the CEBP paper are based on fabricated data and are false.
Sheehy agreed to ask that one of his papers be retracted. The retraction notice has appeared: Continue reading Retraction appears for former federal contractor who faked data
Alfredo Fusco, a cancer researcher in Italy who is facing a criminal investigation for fraud, has had two more papers retracted.
Two researchers at the University of Maryland who retracted a paper earlier this year for a duplicated figure have withdrawn another, this time for unknown reasons.
The Journal of Biological Chemistry (JBC) paper has been cited 16 times, according to Thomson Scientific’s Web of Knowledge.
Here’s the notice, for “Hsp90 Interaction with INrf2(Keap1) Mediates Stress-induced Nrf2 Activation,” which is unfortunately a return to the JBC’s opacity: Continue reading University of Maryland researchers notch second retraction
