Lawsuit against Ole Miss for rescinded Sarkar job offer dismissed; briefs filed in PubPeer case

court caseWe recently obtained court documents showing that, in September, a judge dismissed a lawsuit filed by cancer researcher Fazlul Sarkar against the University of Mississippi after it rescinded a job offer after reviewing concerns raised about his research on PubPeer.

Sarkar’s connection to PubPeer will be familiar to many readers — he has also taken the site to court to force them to reveal the identity of the anonymous commenters who have questioned his findings. He has accused the commenters of defamation, arguing they cost him the job offer. Today, the American Civil Liberties Union filed a brief on behalf of PubPeer’s appeal of the court’s most recent ruling, that the site must disclose the identity of an anonymous commenter. At the same time, some heavy hitters in science – Bruce Alberts and Harold Varmus — and technology — Google and Twitter — filed briefs in support of the appeal.

The lawsuit against Ole Miss has brought to light the reasoning behind the school’s decision to rescind their offer to Sarkar — and the key role played by the concerns raised on PubPeer.

In a letter dated June 19, 2014 to Sarkar from Larry Walker, the director of the National Center for Natural Products Research at the University of Mississippi, Walker chides Sarkar for not revealing the extent of the ongoing questions over his research during the interview process:

Paper on pine tree genetics chopped for duplication

naslovna_vol6_no2A paper on genetic variability in Austrian pine trees apparently didn’t vary enough from other work.

The journal is now retracting the 2012 paper for having significant overlap with another paper published in 2008. Another researcher pointed out the duplication — which was unintentional, according to the note, the result of

an apparent failure in communication between the co-authors on both papers which caused the papers to be overlapped.

The overlapping papers share a first author, Aleksandar Lucic, who works at the Institute of Forestry in Serbia. The other author on both papers is Vasilije Isajev, at the Faculty of Forestry in Belgrade.

Analysis of Genetic Variability of Austrian Pine (Pinus nigra Arnold) in Serbia Using Protein Markers” was published in South-East European Forestry. The journal is not indexed on Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Paper claiming GMO dangers retracted amid allegations of data manipulation

FNS2015012717103119A nutrition journal is retracting a paper about potential dangers of eating food containing genetically modified organisms (GMOs) for duplicating a figure, as news stories from Italy are reporting accusations that the last author falsified some of his research.

In the paper, Federico Infascelli, an animal nutrition researcher at the University of Naples, and his colleagues showed modified genes could wind up in the blood and organs of baby goats whose mothers ate GM soybeans. According to our Google Translate version of an article by Italian newspaper La Repubblicaan investigation suggests that Infascelli has manipulated images to suggest GMOs are harmful. He could face fines and be suspended from the university.

La Repubblica reports that a committee appointed by the rector of the university, Gaetano Manfredi, found errors in Infascelli’s data that suggested he had manipulated the results to show GMOs were harmful.

One paper by Infascelli has been retracted from Food and Nutrition Science, Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean.” The retraction note says the paper was pulled for duplication:

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

Retractions follow misconduct by biologist, one more on the way

Screen Shot 2016-01-06 at 11.11.12 AM

Two journals have retracted papers by a biologist at the University of Tokyo who admitted to scientific misconduct, including data duplication and misrepresentation. Another journal is planning to retract one of the researcher’s papers later this month.

Hyun Kim studies a protein known as the “ski protein.” However, one analysis of the role of ski protein in development was retracted late last month by the Asian-Australasian Journal of Animal Sciences. The journal decided to investigate after Kim admitted to misconduct in two other papers published in a different journal.

Here’s the note for the paper:

Study on eye imaging device withdrawn for German duplication

current eye researchAn article describing a Japanese imaging device that measures eye surface temperature to help diagnose ocular conditions has been retracted because it contained duplicated material that the authors had published previously in German.

Here’s the September retraction note for “Measurement of Dynamic Ocular Surface Temperature in Healthy Subjects Using a New Thermography Device,” published in the journal Current Eye Research in 2012: Continue reading Study on eye imaging device withdrawn for German duplication

Four JBC retractions add up to 8 in total for cancer research pair

47.coverThe Journal of Biological Chemistry is retracting four papers by a pair of cancer researchers at Tulane University, bringing their total to eight.

The retractions are all for reusing parts of figures, either within a paper or from other papers by the pair. Thanks to a new policy at the journal to publish informative notes, we know the figures that were problematic, and the papers that they borrow from. 

An investigation by Tong Wu and Chang Han’s former employer, the University of Pittsburgh, had already led to four retractions for the pair, including two issued this summer.

First up, “Activation of cytosolic phospholipase A2α through nitric oxide-induced S-nitrosylation. Involvement of inducible nitric-oxide synthase and cyclooxygenase-2,” which has been cited 50 times, according to Thomson Scientific’s Web of Knowledge. Here’s the note: Continue reading Four JBC retractions add up to 8 in total for cancer research pair

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:

Osteoporosis paper felled by concerns with “scientific integrity”

cover (3)

A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.”

An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According to the publisher, that duplicated text sparked a closer look at the text, which raised concerns about the scientific integrity of the paper.

The retraction note, published by the Journal of Bone and Mineral Research, says that the first author was responsible for the content of the paper: Continue reading Osteoporosis paper felled by concerns with “scientific integrity”
