A genetics researcher included falsified data in two published papers, according to a report by the U.S. Office of Research Integrity (ORI) released today.
At the time of the misconduct, Andrew Cullinane was a postdoctoral fellow in the Medical Genetics Branch at the National Human Genome Research Institute (NHGRI). According to his LinkedIn page, he is now an assistant professor at Howard University in Washington D.C. The university’s College of Medicine lists him as an assistant professor in the Basic Sciences/Anatomy department.
As today’s notice in the Federal Register reports, Cullinane Read the rest of this entry »
A journal is retracting a paper by scientists at the U.S. Department of Agriculture about a vaccine to protect fish from a deadly bacterial infection, after an investigation found evidence of data manipulation.
The retraction notice — which appears in the journal Vaccine — cites an investigation by the USDA. It also notes that the authors — who are no longer with the USDA — have not agreed to the retraction.
Last year, we reported on an investigation by the University of Colorado Denver into the research of Rajendra Kadam, which recommended retracting 10 papers. The report also flagged eight additional papers co-authored by Kadam whose data could not be validated, raising “concerns as to the scientific validity and integrity” of the material. A few months later, we reported on some of the notices — four retractions and an EOC — that had begun to appear for Kadam’s manuscripts.
We’ve since discovered more notices, bringing his total to seven retractions and three EOCs.
Kadam was once a prominent member in the lab of Uday Kompella, and often referred to by colleagues as the “golden boy,” according to the institution’s report. In 2012, he won a graduate student symposium award from the American Association of Pharmaceutical Scientists.

A pharmacology researcher at Ohio State University has added his seventh retraction, four years after a finding of misconduct by the U.S. Office of Integrity (ORI).
falsified and/or fabricated Western blots in eighteen (18) figures and in six (6) published papers.
In 2012, the ORI finding, which resulted in a three-year funding ban (that is now complete), recommended that Elton retract all six papers, one of which had already been retracted at the time of the report.
Four years later, the last of the six papers flagged by the ORI has finally been retracted by Molecular and Cellular Endocrinology.
A cancer researcher who tried to sue PubPeer commenters for criticizing his work has earned five more retractions, bringing his total to 18.
All of the new retractions for Fazlul Sarkar, formerly based at Wayne State University in Michigan, appear in the International Journal of Cancer. All cite an institutional investigation, and relate to issues with images.
With 18 retractions, Sarkar has now earned a spot on our leaderboard.
We first encountered Sarkar when he subpoenaed PubPeer to reveal the names of anonymous commenters that potentially cost him a job at the University of Mississippi. Earlier this month, a Wayne State spokesperson confirmed to us that Sarkar has now retired from the university. (To get up to speed, check out our timeline on the major events in this case.)
A cancer researcher has earned seven more retractions following an investigation into his work by his former employer, MD Anderson Cancer Center in Texas, bringing his total to 18 retractions.
All of the new retraction notices, issued by The Journal of Biological Chemistry (JBC), stem from image-related issues. The now-retired Aggarwal has seven papers that have each been cited at least 1,000 times, and in 2015, he was on Thomson Reuters Web of Science’s list of The World’s Most Influential Scientific Minds. With these new notices, he also has made it to our leaderboard of individual researchers who’ve racked up the most retractions.

The report flagged eight published papers (and an unpublished one), six of which had already received expressions of concern (EOCs). Nataly Shulga was a co-author on all eight papers. With these two new retractions in Biology Open and Biochimica et Biophysica Acta (BBA) – Bioenergetics, all of the flagged papers have now been retracted.
Here’s the retraction notice for the Biology Open paper, issued July 15:
Are some cases of research fraud fixable with a correction notice?
A chemistry journal thought so in 2014, when it issued a correction notice for a 2012 paper after the first author admitted to manipulating an image. After an investigation, the publisher agreed the manipulation was a “clear breach” of its ethical guidelines, but decided not to retract the paper since the overall conclusions remain valid.
The last author told us the first author had to repeat the experiments under supervision, and received a “serious warning.”
It’s an older notice, but one we thought interesting enough to cover now. Once you’ve read through the journal’s reasoning, tell us if you agree with the decision to correct (rather than retract) the paper in a poll at the bottom of this post.
Here’s the correction for “A novel route for preparing highly proton conductive membrane materials with metal-organic frameworks,” issued by Chemical Communications:
Mousa Abkhezr, the researcher in question, is no longer enrolled at the University of Houston, his former supervisor told us.
In June, the probe into papers co-authored by Abkhezr resulted in the retraction of a study in the American Journal of Physiology – Renal Physiology (AJP). Now, his ex-supervisor, Stuart Dryer, has pulled two more papers co-authored by the pair in Molecular Pharmacology.

A cancer researcher who sued PubPeer commenters for criticizing his work has lost six more papers, bringing his total to 13 retractions.
Four of the new retraction notices issued by the journal Cancer cite an investigation at Wayne State University in Michigan into the work of Fazlul Sarkar and some of his colleagues. All the new notices, including the other two in Breast Cancer Research and Treatment, are for image-related issues.
Retraction Watch readers will recognize the name Fazlul Sarkar, who took PubPeer to court to unmask the anonymous critics whose comments cost him a job at the University of Mississippi. According to this document, Sarkar retired from Wayne State this year.
