You’ve been dupe’d: Meet authors who like their work so much, they publish it twice

fertility and sterility

When our co-founders launched the site in 2010, they wondered whether there would be enough retractions to write about on a regular basis. Five+ years and three full-time staffers later, and we simply don’t have the time to cover everything that comes across our desk.

In 2012, we covered a group of duplication retractions in a single post, simply because duplications happen so frequently (sadly) and often don’t tell an interesting story. So in the interest of bookkeeping, we’re picking up the practice again.

Here are five unrelated retractions for your perusal: all addressing duplications, in which the same – or mostly the same – authors published the same – or mostly the same – information in two different – or sometimes the same – journals.

So, on the buffet table we offer the following entrees: Continue reading You’ve been dupe’d: Meet authors who like their work so much, they publish it twice

Satellite paper grounded for plagiarizing — from the same journal

1-s2.0-S0094576515X00129-cov150hPlagiarism happens; we see it a lot. But some cases stand out from the crowd.

For instance, we just came across an example where authors plagiarized from a paper in the same journal. Specifically, a 2015 paper on satellite orbits was found to have “extensive overlap” with another paper published in Acta Astronautica four years earlier. The last authors of the papers have connections, too — they used to work together at the Vikram Sarabhai Space Centre in India, and in 2006, they co-authored a paper together.

M. Xavier James Raj is author on the retracted paper. He was a PhD student under R.K. Sharma, author of the paper he borrowed from. Sharma currently works at Karunya University in India.

Here’s the retraction note for “Analytical orbit predictions for low and high eccentricity orbits using uniformly regular KS canonical elements in an oblate atmosphere:”

List of retractions, corrections grows for Duke researchers

cov200hDuke researcher Michael Foster and his former co-author Erin Potts-Kant are adding to their notice count with a major correction from late last year to a paper on how certain cells in mice respond to a pneumonia infection, citing “potential discrepancies in the data.”

The correction is actually a partial retraction: The note explains that parts of three figures should be discounted.

We’ve also recently unearthed multiple corrections and two retractions from the pair that we missed from earlier in 2015.

After questions about the data in the corrected paper arose, the authors were able to replicate most of the experiments in the paper, according to the note. But since the paper was published, the senior author passed away, closing her lab, so they couldn’t repeat all of the work.

Here’s the correction notice for “Mast cell TNF receptors regulate responses to Mycoplasma pneumoniae in surfactant protein A (SP-A)−/− mice,” published in The Journal of Allergy and Clinical Immunology:

Renewable energy researcher recycled material, agrees to withdraw 10 papers

S13640321Investigations at two institutions at Taiwan determined in 2013 that a renewable energy researcher duplicated his own work; the researcher agreed to pull 10 papers. A total of six have been withdrawn or retracted, two in November, 2015.

Shyi-Min Lu is the corresponding author on the two newly retracted papers, from Renewable and Sustainable Energy Reviews. The retractions follow investigations at the Industrial Technology Research Institute, where Lu used to work, and National Taiwan University, his former employer. Lu admitted to committing offenses in 10 papers. He was fired from NTU, where he was a research assistant at the university’s Energy Research Center.

First author Falin Chen — also a co-author on the paper duplicated by the retractions — was not aware that the papers bearing his name had been submitted. He told us how he found out:  Continue reading Renewable energy researcher recycled material, agrees to withdraw 10 papers

Cancer Cell paper under investigation following anonymous queries on PubPeer

cancer cell

A Cancer Cell paper that caused a flurry of activity on the website PubPeer is under investigation, after the last author announced on the site that he’d requested a correction from the journal.

The 2012 paper sparked a lively dialogue last month on the post-publication discussion site, as commenters questioned Western blot images in which some bands appeared to be duplicates. The last author responded, noting he had alerted the journal to a “mishap,” and a correction would be forthcoming. However, some commenters remained unsatisfied, and questioned why the correction was taking so long to appear, as well as the explanation for what went wrong.

A spokesman from Cancer Cell confirmed to us the paper is under investigation:

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 note:  Continue reading Misidentified DNA leads authors to retract zebrafish cholesterol paper

Singapore investigation leads to two retractions, two more on the way

cov150hAuthors have retracted papers from Cell Metabolism and the Journal of Biological Chemistry after an investigation in Singapore found issues, including falsified data. The investigation is ongoing, and two additional retractions, along with two corrections, are on the horizon.

The investigation looked into papers by first authors Sudarsanareddy Lokireddy, now a postdoc at Harvard, and Sandhya Sriram, a postdoc at the Agency for Science, Technology and Research in Singapore. Led by the Nanyang Technological University in Singapore, where some of the work was done, the investigation concluded that there were issues with six papers on which either Sriram or Lokireddy was first author.

All authors but Lokireddy have agreed to retractions or corrections. Ravi Kambadur of NTU, and Mridula Sharma at the National University of Singapore, are the last two authors on all the papers.

According to a notice from the NTU, the “investigation found a number of instances of alterations to data” in three papers on which Lokireddy is first author. One of those was retracted December 1 by Cell Metabolism: Continue reading Singapore investigation leads to two retractions, two more on the way

Cancer researcher contributed “false data” to 11 studies

ori-logoA former cancer researcher has falsified data in 11 studies, according to the results of a investigation scheduled to be published in the Federal Register tomorrow.

The Office of Research Integrity’s findings are based on an inquiry at Virginia Commonwealth University, where Girija Dasmahapatra worked until July of this year, investigating possible therapies for cancer. The misconduct affected research funded by three grants from the National Institutes of Health. Steven Grant, a researcher at VCU, is the principal investigator on the grants, each of which total over $2 million in funding. All of the 11 affected papers will be corrected or retracted, according to the ORI notice.

Two of the papers containing “falsified and/or fabricated” data — a study on an experimental combination of drugs for blood cancer and one on chemotherapies for rare forms of lymphoma  — were covered in press releases by VCU.

According to the notice in the Federal Register:

Journal repels a paper on a magnetic material after authorship, funding issues

S03048853

A paper on the properties of a magnetic material is being retracted after including an author without his permission, and omitting a funding source.

According to the note, the work was done in Miao Yu‘s lab at Chongqing University in China; the authors then added Yu’s name to the paper without his authorization, and neglected to list a relevant funding source.

Here’s the retraction note for “Temperature-dependent dynamic mechanical properties of magnetorheological elastomers under magnetic field,” published in the Journal of Magnetism and Magnetic Materials:

Duplication shatters two photonic crystal papers

1-s2.0-S0167577X13X00084-cov150h

Two journals published by Elsevier are retracting a pair of material science papers that appear to share figures.

The papers  — in Materials Letters and Optics Communications — discuss photonic crystals, a kind of material used to manipulate light. They share the same first author, Zheng-qi Liu at Jiangxi Normal University and  Nanjing University in China, as well as six other authors. Each paper presents one of the duplicated figures as a slightly different material.

One of the duplicated figures is a a picture of a photonic crystal taken with a scanning electron microscope that gives detail at the level of a few micrometers (it looks like a honeycomb, but it’s composed of tiny spheres). It’s Figure 1a in both papers:
