Researchers are retracting two papers about molecular signalling in plants — including one from the Proceedings of the National Academy of Sciences (PNAS) — after discovering some inadvertent genotyping errors. But that was only after they used the problematic plants for an entire year without realizing they’d made a mistake.
In a pair of refreshingly transparent and detailed notices, the authors explain that the transgenic plants used in the papers included genotyping errors, which invalidated their findings. According to the notices, first author Man-Ho Oh generated the problematic transgenic plants, while corresponding author Steven C. Huber, based at University of Illinois, Urbana-Champaign (UIUC), took responsibility for omitting some critical oversight.
Huber told us that there were only two papers that used the transgenic plants in question, so no other retractions will be forthcoming.
The authors revisited their experiments after another lab was unable to replicate their data, about proteins that may play a role in lung cancer.
The first author told Nature News in 2013 that the paper may have helped her secure her current position at the Novartis Institutes for Biomedical Research in Massachusetts.
Pulling “Cytohesins are cytoplasmic ErbB receptor activators” appears to be a case of doing the right thing, given the detailed retraction notice:
If you need evidence of the value of transparency in science, check out a pair of recent corrections in the structural biology literature.
This past August, researchers led by Qiu-Xing Jiang at the University of Texas Southwestern Medical Center corrected their study, first published in February 2014 in eLife, of prion-like protein aggregates called MAVS filaments, to which they had ascribed the incorrect “helical symmetry.” In March, Richard Blumberg of Harvard Medical School, and colleagues corrected their 2014 Nature study of a protein complex called CEACAM1/TIM-3, whose structure they had attempted to solve using x-ray crystallography.
In both cases, external researchers were able to download and reanalyze the authors’ own data from public data repositories, making it quickly apparent what had gone wrong and how it needed to be fixed — highlighting the very best of a scientific process that is supposed to be self-correcting and collaborative.

The October paper examined the effects of climate change on populations of 155 species of British moths and butterflies. According to a press release from the authors’ institution, the University of York:
Using data collected by thousands of volunteers through ‘citizen science’ schemes, responses to recent climate change were seen to vary greatly from species to species.
The standard in transparency? Editor praises author honesty that led to retraction in anesthesia journal
Sometimes, a junior member of the team sees things an editor-in-chief misses.
Regular readers know that we’re always delighted when we get a chance to commend researchers and journals for doing the right thing. Here’s an example that sets the standard.
Anesthesia & Analgesia (A&A) is retracting a 2015 paper which purportedly found important differences in patient outcomes based on the quality of their anesthesiologists. The trouble with the article: Read the rest of this entry »
It’s a somewhat unusual notice — it explains that the paper has been retracted and replaced with a new, corrected version.
The study, which included 452 adults with major depressive disorder, concluded that cognitive therapy plus medication works better to treat depression than pills alone. But after it was published, a reader pointed out that some of the numbers in a table were incorrect. The authors reviewed the data and redid their analysis, and discovered “a number of pervasive errors.”
The notice (termed “notice of retraction and replacement”) explains the consequences of those errors:
After publishing a paper about neuropathy in diabetic patients last week, The New England Journal of Medicine (NEJM) immediately corrected it after editors learned of errors and some missing disclosures within the article.
The notice explains that the sole author of the paper, “Diabetic Sensory and Motor Neuropathy,” reported incorrect doses for several medications, and received royalties for the tool to measure quality of life used in the paper. The author told us all the declarations were “discussed in detail” between him and the journal, and both parties agreed to the final decision.
There was a big problem in how you generate a magnetic field, and now, because of our results, that problem has basically gone away.

A journal has retracted a paper about 3D imaging after concluding the authors used equations from another researcher without attribution — and has conveniently included a detailed editorial explaining exactly what happened.
It’s rare for us to see a journal be so transparent in explaining what went wrong with one of its papers, so we’re thanking Stuart Granshaw, from Denbighshire in Wales, UK, the editor of The Photogrammetric Record, for “doing the right thing.”
Authors have retracted two papers about visual perception and working memory from the Journal of Cognitive Neuroscience, after the first author admitted to falsifying or fabricating data in four other papers.
The authors have requested another two retractions, as well, which will bring the total for Edward Awh and his former graduate student David Anderson to nine retractions. (Earlier in 2015, they lost a paper due to an error in the analytic code, which Awh told us was unrelated to the misconduct.)
The retraction notice attached to both articles cites a 2015 settlement agreement between the Office of Research Integrity and first author Anderson (the “respondent”), who admitted to misconduct while working as a graduate student in the lab of Awh at the University of Oregon in Eugene. Since then, “additional problems” were discovered in the newly retracted articles, such as removed data points.
