Physicists retract Nature paper on Earth’s core after findings aren’t reproducible

cover_naturePhysicists have retracted a highly cited paper from Nature on the behavior of electrons at the center of the Earth after other researchers could not reproduce their findings.

The 2015 paper earned coverage in Science News and Live Science, where co-author Ronald Cohen explained:

There was a big problem in how you generate a magnetic field, and now, because of our results, that problem has basically gone away.

Here are more details about what the original paper claimed, courtesy of a press release from The Carnegie Institution for Science, where co-authors Peng Zhang and Cohen work: Continue reading Physicists retract Nature paper on Earth’s core after findings aren’t reproducible

Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

The Photogrammetric Record

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.”

Even the retraction note is reasonably forthcoming: Continue reading Now this is transparent: Retraction for plagiarism earns 4-page editor’s note

More retractions bring total to 7 for neuroscience pair, 2 more pending

JOCNAuthors 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.

Awh, who has since moved to the University of Chicago, sent us a lengthy statement, explaining the concerns about each article: Continue reading More retractions bring total to 7 for neuroscience pair, 2 more pending

Labor pains study brought into this world twice

YJPAI_v16_i6_COVER.inddA group of authors published two articles about one study on pain during childbirth, so one journal is retracting it.

This may seem like a standard case of salami slicing — but this one comes with a nearly 600-word commentary co-authored by the editors of the two journals in question.

The commentary lays out — in a refreshingly transparent way — exactly why the journals came to a joint decision to retract one of the papers:

Makeup use linked to testosterone levels? Not so fast, says retraction

Psych SciA psychology journal is retracting a 2015 paper that attracted press coverage by suggesting women’s hormone levels drive their desire to be attractive, after a colleague alerted the last author to flaws in the statistical analysis.

The paper, published online in November, found women prefer to wear makeup when there is more testosterone present in their saliva. The findings were picked up by various media including Psychology Today (“Feeling hormonal? Slap on the makeup”), and even made it onto reddit.com.

However, upon discovering a problem in the analysis of the data, the authors realized that central finding didn’t hold up, according to Psychological Science‘s interim editor, Stephen Lindsay: Continue reading Makeup use linked to testosterone levels? Not so fast, says retraction

News site The Intercept says reporter created fake quotes, sources

interceptThe Intercept is apologizing to readers after an investigation revealed one of its reporters fabricated multiple quotes and even created a fake email address for a source to deceive his editors.

The online news site is retracting and correcting several articles by former staff writer Juan Thompson, who was employed there from November 2014 until last month.

In a note issued earlier today, editor Betsy Reed revealed some details of the results of the investigation to readers:

What to do when you make a mistake? Advice from authors who’ve been there

cpp-150After a group of researchers noticed an error that affected the analysis of a survey of psychologists working with medical teams to help pediatric patients, they didn’t just issue a retraction — they published a commentary explaining what exactly went wrong.

The error was discovered by a research assistant who was assembling a scientific poster, and noticed the data didn’t align with what was reported in the journal. The error, the authors note, was:

an honest one, a mistake of not reverse coding a portion of the data that none of the authors caught over several months of editing and conference calls. Unfortunately, this error led to misrepresentation and misinterpretation of a subset of the data, impacting the results and discussion.

Needless to say, these authors — who use their “lessons learned” to help other researchers avoid similar missteps — earn a spot in our “doing the right thing” category. The retraction and commentary both appear in Clinical Practice in Pediatric Psychology.

Their first piece of advice in “Retraction experience, lessons learned, and recommendations for clinician researchers” — assume errors will happen, and not vice versa: Continue reading What to do when you make a mistake? Advice from authors who’ve been there

Misidentified DNA leads authors to retract zebrafish cholesterol paper

cov150h

Authors are retracting a 2012 paper on cholesterol metabolism in zebrafish after realizing it included a case of mistaken identity in a DNA sequence crucial to some aspects of the experiment.  

A postdoc misidentified the plasmid in question after failing to fully sequence it before including it in the experiment. A technician in the lab found the mistake, last author Steven Farber, a researcher at the Carnegie Institution for Science in Maryland, explained:

When the omitted region was correctly sequenced we discovered it had an error.

He told us in a phone interview what that felt like:

We were like, holy crap.

Next came months of back and forth with the journal, discussing whether to correct or retract the paper. Farber tells us the mistake, which affects two figures,

was unfortunate. Most of the paper is in fact correct.

The paper, “Visualization of Lipid Metabolism in the Zebrafish Intestine Reveals a Relationship between NPC1L1-Mediated Cholesterol Uptake and Dietary Fatty Acid,” published in Chemistry & Biology, has been cited 21 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the detailed retraction noteContinue reading Misidentified DNA leads authors to retract zebrafish cholesterol paper

Neuroanatomy paper riddled with errors pulled by authors

Journal-of-NeurosurgeryAuthors have retracted a paper from the Journal of Neurosurgery that contained many errors, including mislabeled figures, anatomical errors, and mismatched citations. They said that the paper’s preparation was rushed and not all authors had a chance to verify that it was accurate.

Two of the authors of the paper had previously contacted the journal to request the paper be withdrawn. Jo Ann Eliason, communications manager for the Journal of Neurosurgery, said that the withdrawal request came too late, since the paper had already been published online: Continue reading Neuroanatomy paper riddled with errors pulled by authors

E. coli gene paper falls to mistaken mutation

asmcoverResearchers in Germany have retracted their 2011 article in the Journal of Bacteriology after another lab pointed out a fatal error in the paper.

The article, “Escherichia coli Exports Cyclic AMP via TolC,” came from a group at Tübingen University led by Klaus Hantke. The paper focuses on the crucial role of the membrane channel TolC in exporting cyclic AMP (cAMP)-cAMP receptor protein (CRP) complex, which regulates nearly 200 E. coli genes. According to the abstract:

The data demonstrate that export of cAMP via TolC is a most efficient way of E. coli to lower high concentrations of cAMP in the cell and maintain its sensitivity in changing metabolic environments.

But the conclusions rested on a gene mutation that wasn’t quite what it seemed. Here’s the notice: Continue reading E. coli gene paper falls to mistaken mutation
