Headline-grabbing Science paper questioned by critics

When zoologists at the University of Oxford published findings in Science last year suggesting ducklings can learn to identify shapes and colors without training (unlike other animals), the news media was entranced.

However, critics of the study have published a pair of papers questioning the findings, saying the data likely stem from chance alone. Still, the critics told us they don’t believe the findings should be retracted.

If a duckling is shown an image, can it pick out another from a set that has the same shape or color?  Antone Martinho III and Alex Kacelnik say yes. In one experiment, 32 out of 47 ducklings preferred pairs of shapes they were originally shown. In the second experiment, 45 out of 66 ducklings preferred the original color. The findings caught the attention of many media outlets, including the New York Times, The Atlantic, and BuzzFeed.

Martinho told us:

Huh? Cancer paper gets retracted because of its correction

Here’s a rather odd case: When readers raised issues about some of the images in a 2008 cancer paper, the authors issued a correction last year. But when readers asked additional questions about the corrected images, the authors decided to retract the paper entirely, along with its correction.

Both the original and corrected versions were questioned on PubPeer.

Here’s the retraction notice for the 2008 article “PRIMA-1MET induces mitochondrial apoptosis through activation of caspase-2,” published in Oncogene, which includes a link to the July 2016 correction: Continue reading Huh? Cancer paper gets retracted because of its correction

15-year old paper pulled for image problems

A group of researchers in France has been forced to retract their 2002 article in the Journal of Virology after learning that the paper was marred by multiple image problems.

The paper, “P0 of Beet Western Yellows Virus Is a Suppressor of Posttranscriptional Gene Silencing,” came from the lab of Veronique Ziegler-Graff, a plant biologist at the University Louis Pasteur, in Strasbourg. The authors attribute some of the image problems to “genuine mounting mistakes,” and have repeated the experiments to confirm the conclusion, as have other labs. However, the researchers couldn’t find all the original data from the 2002 paper.

Although the retraction statement points the finger at the first author, Sebastien Pfeffer, the list of contributors includes Patrice Dunoyer, a frequent collaborator of Olivier Voinnet, a high-profile plant biologist whose work has come under intense scrutiny.

According to the lengthy notice:

“Knowledgeable informant” outs researchers for falsifying data

A pathology journal has retracted a 2015 paper from researchers in China after concluding the authors had falsified and copied some of the data and text.

According to the notice, a “knowledgeable informant” told the journal about the overlap and “fraudulent” aspects of the paper, which the editors were able to confirm. The journal retracted the paper last month.

Here’s the retraction notice for “Genistein attenuates glucocorticoid-induced bone deleterious effects through regulation Eph/ephrin expression in aged mice:”

Journal flags another paper by diabetes researcher who sued to stop retractions

It would seem that resorting to legal means to avoid editorial notices doesn’t always work.

We’re coming to that conclusion after seeing yet another notice for Mario Saad, based at the University of Campinas in São Paulo, Brazil. In this case, it’s an expression of concern from the Journal of Endocrinology, on a 2005 paper that lists Saad as the second-to-last author. According to the notice, the journal is concerned the paper contains spliced and duplicated images; although the authors offered to repeat the experiments, the journal considered that potential delay “unacceptable.”

Despite Saad’s legal efforts, he is now up to 11 retractions, along with multiple expressions of concern.

Here’s the full text of the notice (which is paywalled, tsk tsk):

Prominent physicist loses paper over data falsification

A paper by a promising nanotechnologist has been retracted for data falsification.

Dmitri Lapotko, a Belarusian researcher with a background in laser weaponry, made a name for himself at Rice University in Houston, where he studied the use of nanotechnology to diagnose and treat human diseases. That work earned him significant press coverage, including stories in the New York Times and Science.

But that nanobubble may be bursting. The journal Theranostics has retracted a 2011 paper on which Lapotko is the last and corresponding author, citing questions over data falsification. What’s more, another journal has warned readers there may be a problem with a figure in a 2012 paper on which Lapotko is listed as last author.

Lapotko has since left Rice for Masimo Corp., a developer of monitoring devices for patients in the operating room.

According to the Theranostics notice:

Cancer researcher has dodged accusations for decades (and has a new correction)

Today isn’t a great day for Carlo Croce, chair of the department of cancer biology and genetics at The Ohio State University (OSU).

The New York Times has a lengthy article detailing the misconduct accusations that have swirled around Croce for years. We’ve covered many, but The Gray Lady obtained documents that show there have been many more.

The story mentions a 2013 letter from Ohio State University to pseudonymous whistleblower Clare Francis (which we reported on in 2014), acknowledging Francis’s allegations against Croce. However, in the letter, an administrator said OSU saw no reason to investigate Croce.

The story didn’t stop there, as the Times reports:

Something new: A journal publishes running tally of retractions

Here’s something we haven’t seen before: A journal based in Serbia recently began listing all the articles it has retracted, all due to plagiarism.

Although preventing plagiarism is hardly a new goal for journals, creating a web page dedicated to retractions is certainly a novel attempt. (Even the home page has a link to the page, called “Retracted Articles.”)

This past February, the Journal of Process Management – New Technologies International did exactly that. Currently, this page on the journal’s website features five papers, all retracted in 2016, along with links to notices which indicate the original, plagiarized article.

First, let’s list the notice for “Impact of shopper’s creativeness on shopping methods: A case-study of students of University of Delhi (India),” published in 2014:

“Hindsight’s a bitch:” Colleagues dissect painful retraction

Two blog posts are shining additional light on a recent retraction that included some unanswered questions — namely, the identity of the researcher who admitted to manipulating the results.

To recap: Psychological Science recently announced it was retracting a paper about the relationship between the words you use and your mood after a graduate student tampered with the results. But the sole author — William Hart, an assistant professor at the University of Alabama — was not responsible.

The post raised some questions — for instance, who was the graduate student, and if his or her work was so influential to a paper, why was he/she not listed as an author? Hart declined to identify the student, but two new blogs — including one by one of Hart’s collaborators at the University of Alabama — are providing more details.

Author says he lied about approval for animal research

A researcher in South Korea has retracted a 2015 paper after telling the journal he falsified the institutional approval required to conduct the animal experiments.

In the article, the author explicitly says that the Animal Experiment Review Board of a university based in Seoul, South Korea approved the experiments, but according to the journal, “the author did not receive an approval by the board and he used a false approval number.”

Here’s the retraction notice for “The role of compensatory movements patterns in spontaneous recovery after stroke,” published in the Journal of Physical Therapy Science (JPTS) in September 2015 and retracted in December: Continue reading Author says he lied about approval for animal research
