A former postdoctoral researcher at the Mount Sinai School of Medicine in New York has received a five-year funding ban after an investigation concluded that they had falsified data underlying more than 50 images.
The ORI investigation into the work of Kenneth Walker, determined that he had
falsified and/or fabricated quantitative real-time polymerase chain reaction (qPCR) data to demonstrate a statistically significant or “trend” of statistical difference in the expression of renal or bladder urothelium and muscle developmental markers between control and experimental (mutant) mice, when there was none.
The ORI report said that Walker has agreed to retract or correct a 2013 PLOS ONE paper and a 2015 study published in American Journal of Physiology – Renal Physiology (AJPRP).
A vociferous advocate for correcting the literature — who has been banned by two publishers for his persistent communications — has asked journals to retract one paper and correct three others for duplications.
It’s rare for the U.S. government to revoke grants – but it happened recently, according to a report this week by the Kentucky Center for Investigative Reporting (KyCIR). As the report notes, in March the government revoked $914,000 in funding awarded to Susan Harkema at the University of Louisville in Kentucky, after discovering problems with a study that examined whether the muscle relaxant baclofen helps paralyzed patients move on treadmills. (The university has denied it lost any government funding; a representative of Louisville Public Media, which houses the KyCIR, is standing by the story.) All of this has not been news to Steve Williams, a physician now based at the University of Washington, who has been raising questions about the study for years.
Retraction Watch: What was your role in the study in question, that’s now been defunded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILIRR)?
Steve Williams: I was the study physician who evaluated patients for enrollment.
A cancer journal has retracted a paper co-authored by a researcher who falsified or fabricated data in 11 studies, according to an investigation by the Office of Research Integrity (ORI).
In December 2015, an ORI probe into the work of Girija Dasmahapatra concluded that he had
…duplicated, reused, and/or relabeled Western blot panels and mouse images and claimed they represented different controls and/or experimental results…
Dasmahapatra left the Virginia Commonwealth University (VCU) in July 2015.
A research fellow at Harvard has lost his PhD from a university in Singapore after being found guilty of falsifying data, and his former group leader’s contract has been terminated by his institution.
But that’s not the whole story. This tangled mess involves not only the Harvard researcher, Sudarsanareddy Lokireddy, and his former boss, Ravi Kambadur at the Nanyang Technological University (NTU) in Singapore, but an as-yet unnamed colleague of theirs who, we’re told, has admitted making up data in three papers, on which Lokireddy and Kambadur are co-authors. Bear with us as we walk you through this tale.
Two of those papers have been retracted by The Journal of Biological Chemistry (JBC); one in Molecular Endocrinology has yet to be pulled. Kambadur, who held joint appointments at the NTU and the Agency for Science, Research and Technology (A*STAR) in Singapore, has now had his contract terminated at both institutions.

Two researchers found to have faked data by the U.S. Office of Research Integrity (ORI) have lost a paper that they co-authored.
According to the ORI report issued on May 25, Ricky Malhotra, one of the researchers in question, admitted to fabricating 74 experiments, and falsifying well over 100 Western blots while at the Universities of Michigan (UM) and Chicago (UC). One week later, the ORI issued additional findings about Karen D’Souza, a colleague of Malhotra’s at the UC, concluding that she had also falsified some data.
Both researchers agreed to the retraction of a 2010 paper published in The Journal of Biological Chemistry (JBC), the reports note.
Last week, a study brought into question years of research conducted using the neuroimaging technique functional magnetic resonance imaging (fMRI). The new paper, published in PNAS, particularly raised eyebrows for suggesting that the rates of false positives in studies using fMRI could be up to 70%, which may affect many of the approximately 40,000 studies in academic literature that have so far used the technique. We spoke to the Anders Eklund, from Linköping University in Sweden, who was the first author of the study. Continue reading Is the bulk of fMRI data questionable?
PLOS ONE has retracted a malaria paper after an institutional investigation found evidence the authors had manipulated multiple figures.
According to the notice, the authors’ institution — the International Centre for Genetic Engineering and Biotechnology (ICGEB) in New Delhi, India — recommended the journal retract the paper.
An erstwhile cell biologist has retracted five papers published in the Journal of Cell Science (JCS), all of which had been flagged in a recent investigation by the U.S. Office of Research Integrity (ORI).
The investigation found John Pastorino, previously a cell biologist at Rowan University in New Jersey, guilty of doctoring more than 40 images, resulting in a five-year funding ban.
The probe identified eight papers co-authored by Pastorino, six of which had already received expressions of concern (EOC) — including all of the newly retracted JCS papers. Nataly Shulga is a co-author on all eight papers.
