Bharat Aggarwal, a highly cited cancer researcher who retired last year from MD Anderson, has logged two retractions following an investigation into his work, bringing his total to nine.

Aggarwal has threatened to sue us in the past, and told us that MD Anderson has been investigating his work. Earlier this year, Biochemical Pharmacology retracted seven studies of which he is the only common author, noting the “data integrity has become questionable.” Now, he’s earned two more retractions in Molecular Pharmacology, both for “inappropriate” or “unacceptable” image manipulation.

Both of the notices are paywalled (tsk, tsk). Here’s one for “Flavopiridol suppresses tumor necrosis factor-induced activation of activator protein-1, c-Jun N-terminal kinase, p38 mitogen-activated protein kinase (MAPK), p44/p42 MAPK, and Akt, inhibits expression of antiapoptotic gene products, and enhances apoptosis through cytochrome c release and caspase activation in human myeloid cells:” Continue reading Highly cited cancer researcher logs 8th, 9th retractions

Fazlul Sarkar, who sued PubPeer commenters for criticizing his work, has logged two more retractions, bringing his total to seven.

The two retractions appear in the Journal of Cellular Physiology, and follow five others released last week by another Wiley journal, Journal of Cellular Biochemistry. All notices mention an investigation at Wayne State University, where Sarkar is on the faculty.

Here’s the notice for “Activated K-Ras and INK4a/Arf Deficiency Promote Aggressiveness of Pancreatic Cancer by Induction of EMT Consistent With Cancer Stem Cell Phenotype:” Continue reading Seventh retraction appears for cancer researcher who sued PubPeer commenters

Fazlul Sarkar

An investigation at Wayne State University has prompted five retractions for a scientist who is suing PubPeer commenters after they criticized his work on the site.

The investigation into Fazlul Sarkar and his co-authors found that the papers contain images that were “inappropriately manipulated” or “inappropriately re-used and re-labeled.” All five retraction notices are from the Journal of Cellular Biochemistry.

Here’s the retraction notice for “Concurrent inhibition of NF-κB, cyclooxygenase-2, and epidermal growth factor receptor leads to greater anti-tumor activity in pancreatic cancer:

More than $100M worth of research may be tainted by govt lab misconduct

usgsMisconduct by a chemist at a Colorado lab run by the U.S. Geological Survey (USGS) has potentially affected  24 research and assessment projects, supported by $108 million in federal funding, government officials have disclosed.

According to a June 15 statement from the Office of the Inspector General of the U.S. Department of the Interior, which oversees the USGS, the operator of a mass spectrometer in the Inorganic Section of the Energy Resources Program’s (ERP) Energy Geochemistry Laboratory in Lakewood has been accused of scientific misconduct and manipulating data. The unit is responsible for conducting coal and water quality assessments in projects both in the United States and abroad.

The inorganic section closed following the discovery of the misconduct, and we have yet to learn the fate of the employee involved. As the statement notes, problems with the lab’s data were common knowledge among workers at the facility: Continue reading More than $100M worth of research may be tainted by govt lab misconduct

The self-proclaimed “father of nutritional immunology,” Ranjit Kumar Chandra, has lost two more papers following the release of a misconduct investigation report by his former employer, Memorial University of Newfoundland (MUN).

The report was released last year after Chandra lost his libel suit against the Canadian Broadcasting Company (CBC). The newly retracted papers were both published in Nutrition Research. On one, the author is listed as “Amrit Jain,” who is allegedly Chandra, as well.

Here’s the retraction notice for the article by Amrit Jain:

Figures questioned online were manipulated, says Malaysia investigation

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:

Journal retracting at least nine articles by education researcher

JAASEPA investigation in Singapore has failed to turn up primary data that formed the basis for 11 papers from one author about special education.

In addition, a forensic investigation at Noel Chia’s institution — the National Institute of Education in Singapore, part of Nanyang Technological University (NTU) — suggested that some signatures providing parental consent might not be authentic. The investigation was also unable to authenticate the Malaysia-based organization Chia said collected the data on his behalf.

Nine of the papers appear in the Journal of the American Academy of Special Education Professionals (JAASEP), which has declared it plans to retract every article Chia has ever published with them (we’ve counted an additional nine papers).

Much of the information we know about the case stems from the unusually detailed — 3,000 word — retraction notice from JAASEP:

Fraudster loses third attempt to remove 7-year debarment

court caseA U.S. judge has denied a virology researcher’s third attempt to overturn a seven-year debarment from receiving federal funds, following a 2010 decision by the U.S. Office of Research Integrity.

The ORI banned Scott Brodie for seven years after concluding he had committed 15 acts of misconduct at the University of Washington. The deception affected grant applications, published papers, manuscripts, and presentations. Since then, Brodie has tried multiple times to reverse the ruling in court.

In the latest decision, dated June 13, United States District Judge James E. Boasberg writes: Continue reading Fraudster loses third attempt to remove 7-year debarment
