Genetics study flagged for reliability issues by Frontiers journal

frontiers-in-geneticsA genetics journal has issued an expression of concern (EOC) for a study after an investigation by its chief editors.

According to the notice in Frontiers in Genetics, the authors of the paper — based at Hokkaido University in Sapporo, Japan — are conducting further experiments to resolve the issues raised by the journal’s investigation.

In February, the same paper received a corrigendum due to errors in the assembly of one of the figures.

Here’s the EOC, issued earlier this week: Continue reading Genetics study flagged for reliability issues by Frontiers journal

Journal pulls plug on paper that predicts person’s death, against authors’ objections

frontier-in-human-neuroscienceSome people can look at an old photograph of a person — say, of your grandmother in elementary school — and tell whether the person is today alive or dead, according to a paper published last spring.

If that sounds too weird to be true…well, it might be. The journal editors have retracted the paper for not having enough evidence to back up its claims, despite the authors’ objections.

Here’s the retraction notice for “Prediction of Mortality Based on Facial Characteristics,” published in Frontiers in Human Neuroscience:

Authors didn’t generate key brain images, probe finds

Frontiers in Human NeuroscienceA neuroscience journal has issued a retraction after discovering some of the paper’s integral images didn’t originate from the authors’ labs.

The retraction notice  — for a study about a condition once known as “water on the brain” — cites an investigation by the journal’s publisher, Frontiers, which determined that the figures were not “duly attributed.” The authors say they agree with the retraction.

Author lifts from one paper in two different articles. Why does one journal retract, while the other corrects?

circ resAre there instances when similarities between papers should be fixed by a correction, rather than a retraction?

We’re asking ourselves that question after seeing two journals take very different approaches to a somewhat similar situation. Last year, Frontiers in Physiology retracted a paper by Anastasios Lymperopoulos at Nova Southeastern University in Florida because of an “an unacceptable level of similarity” to a 2009 review article by different authors. But more recently, after Circulation Research discovered another paper co-authored by Lymperopoulos also contained similar text from the same 2009 review, it decided to correct the passages.

The last author of the Circulation Research paper told us the overlap between the two papers was less than 5%, and the journal never suggested the authors retract the paper.

Here’s the correction notice in Circulation Research:

Author loses 2nd paper on supposed dangers of chemtrails

Frontiers in Public HealthAgainst the author’s wishes, a journal has retracted a paper about chemtrails, a long-standing conspiracy theory about the dangers of cloud trails released from jet planes.

After the paper was scrutinized on librarian Jeffrey Beall’s blog and social media last week, Frontiers in Public Health issued an expression of concern (EOC). The paper was published June 30, and retracted yesterday, in a relatively rare case of rapid action by a journal. 

Last year, we reported on another retraction of a paper about chemtrails by the same author — J. Marvin Herndon, a geophysicist and self-described “independent researcher” at the Transdyne Corporation in San Diego, California.

Here’s the retraction notice: Continue reading Author loses 2nd paper on supposed dangers of chemtrails

Controversial chemtrails paper flagged by journal

Frontiers in Public HealthA journal has published an expression of concern (EOC) for a 2016 paper providing evidence for a long-standing conspiracy theory about the dangers of cloud trails from jet planes.

A similar paper by the same author was retracted last year by another journal.

Both papers focused on the “chemtrails” emitted from jet planes, which conspiracy theorists have long believed contain toxic coal fly ash rather than harmless ice crystals, as the government claims. According to a press release about the 2016 paper, released by author J. Marvin Herndon, a geophysicist and “independent researcher” at the Transdyne Corporation in San Diego, California, the paper presents evidence the chemtrails contain coal fly ash, linked to a number of health problems.

But many people disagree with the findings — Jeffrey Beall, a librarian at the University of Colorado, Denver, criticized the paper on his blog.

Here’s the EOC, published today by Frontiers in Public Health: Continue reading Controversial chemtrails paper flagged by journal

Genotyping mistake costs lab two papers and year of work

PNASResearchers 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.

Here’s the notice in PNAS for “Autophosphorylation of Tyr-610 in the receptor kinase BAK1 plays a role in brassinosteroid signaling and basal defense gene expression:”  Continue reading Genotyping mistake costs lab two papers and year of work

Figures questioned online were manipulated, says Malaysia investigation

The image that excited twitter: Figure 6 from the Scientific Reports paper
The image that set Twitter abuzz: Figure 6 from the Scientific Reports paper, in which every cell in each stage of cell death appeared to be an exact copy.

Many figures in four papers by a research team in Malaysia contain duplication or manipulation, a university committee has found, calling for multiple retractions.

We learned about issues with three of the papers, including one in Scientific Reports, earlier this week when they were the talk of Twitter. As journals issued expressions of concern, and an expert wondered how the papers passed peer review at all, the first author, a researcher at the University of Malaya (UM), denied allegations of duplication.

UM was alerted to allegations of misconduct in the Scientific Reports paper last Saturday, and according to a statement published today:

Images that raised eyebrows flagged by another journal; Malaysian gov’t investigates

Screen Shot 2016-06-15 at 9.17.15 AMMultiple investigations have been launched into allegations of blatant duplications by a research group in Malaysia.

Last week, users alleged on Twitter that three papers by the same team included pictures of cells that were copied and pasted. First author Nima Samie, affiliated with University of Malaya in Malaysia, denied the accusations — but both the Malaysian government and now two journals sees cause for further investigation.

Frontiers in Pharmacology published an expression of concern this morning:

Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Frontiers in PharmacologyAgainst the authors’ wishes, a pharmacology journal has retracted a paper after receiving two messages questioning the “soundness of the experimental results.”

The editors of the journal, Frontiers in Pharmacology, issued an expression of concern about the paper in April 2016, and investigated it following the allegations. According to the retraction notice, the authors disagree with the retraction.
