A graduate student at the University of Oregon in Eugene has admitted to faking data that appeared in four published papers in the field of visual working memory, according to the Office of Research Integrity.
David Anderson’s supervisor at the time was Edward Awh, who has since moved to the University of Chicago.
Anderson told Retraction Watch that the misconduct stemmed from “an error in judgment”:

A former postdoctoral fellow at Penn State University faked numerous data and analyses in a manuscript submitted to Molecular Cancer Research, according to the Office of Research Integrity (ORI).
In a notice released today, the ORI found Julie Massè: Continue reading Penn State postdoc faked data in cancer manuscript
An official inquiry by the University of Pittsburgh has led to two more retractions for a pair of cancer researchers, Tong Wu and Chang Han. By our count, the pair now have four retractions under their belt, all the result of the university investigation.
The Journal of Biological Chemistry published the notices earlier this month, after it was discovered the papers contained cropped panels, among other issues. Importantly, the two papers appear to even have shared some data.
One 2006 paper, “Modulation of Stat3 Activation by the Cytosolic Phospholipase A2α and Cyclooxygenase-2-controlled Prostaglandin E2 Signaling Pathway,” investigated the molecular actors in cancer growth, such as overexpression of cyclooxygenase-2 (COX-2). It has been cited 34 times, according to Thomson Scientific’s Web of Knowledge. Here’s the notice:
A prominent endocrinologist pathologist has resigned from running the largest hospital diagnostic laboratory in Canada following an investigation that has uncovered evidence of falsified data in two papers, Retraction Watch has learned.
Sylvia Asa was the Program Medical Director of the Laboratory Medicine Program at the University Health Network, affiliated with the University of Toronto, until this past spring when she stepped down, according to UHN spokesperson Gillian Howard:

2013 was a rough year for biologist Pamela Ronald. After discovering the protein that appears to trigger rice’s immune system to fend off a common bacterial disease – suggesting a new way to engineer disease-resistant crops – she and her team had to retract two papers in 2013 after they were unable to replicate their findings. The culprits: a mislabeled bacterial strain and a highly variable assay. However, the care and transparency she exhibited earned her a “doing the right thing” nod from us at the time.
After many months spent understanding what went wrong and redoing the experiments correctly, today Ronald and her team release another paper in Science Advances that reveals the protein they thought they had identified in 2013.
Ronald and co-first author Benjamin Schwessinger (who recently became an independent research fellow at the Australian National University in Canberra) spoke to us about the experience of recovering from the retractions and finally getting it right. The conversation has been edited for brevity and clarity.
-What did you do differently this time so you didn’t repeat the same mistakes?
A review paper that suggested the degenerative brain disease that’s striking former football players may not be tied to contact sports has been corrected to reveal the first author spent decades working for the National Football League.
The correction appears in a review in PLOS ONE about chronic traumatic encephalopathy – the degenerative brain disease that was the basis of a $765 million settlement for former NFL players, along with a number of similar lawsuits. It fixes incorrect statements and adds conflicts of interest, including those with with first author Joseph Maroon, who spent more than 30 years working with the NFL and seven for the wrestling group the WWE.
It appears as if all the original paper declared was that Maroon was an “unpaid consultant” to the Pittsburgh Steelers. But apparently there was a lot more to it, according to the notice:
Cell biologist Jacob Hanna, the highly cited stem cell researcher currently at the Weizmann Institute of Science, has posted a long erratum for a 2005 paper in Blood for “inadvertent mistakes,” among other issues; soon after, Hanna’s team issued another erratum for a 2009 Cell Stem Cell paper.
There’s more to tell: Last month, commenters on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.
Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:

As a consequence for academic “negligence” which resulted in two retractions, biologist Jens Schwamborn was banned from seeking funding from German funding agency DFG for one year.
The ban — which ended in March, 2015 — was the result of an investigation by DFG and the University of Münster, which reviewed the issues that led to retractions of two papers about neuron development, one in The EMBO Journal, and another in the Journal of Biological Chemistry.
Here’s the official statement on the ban, sent to us by Head of Communications Britta Schlüter at the University of Luxembourg, where Schwamborn now works:

More journals have pulled papers co-authored by researchers Erin Potts-Kant and Michael Foster, at Duke University, bringing the total up to seven for Potts-Kant and six for Foster.
Authors were unable to replicate the experiments after “concerns about the initial data from the animal physiology laboratory” led them to reanalyze source data, according to the note in Environmental Health Perspectives. The comparison showed “potential inconsistencies in the data,” which “significantly impact the overall conclusions of the manuscript.” Similar issues appear to have felled the pair’s other papers, including the other two recent retractions in the American Journal of Respiratory and Critical Care Medicine and the American Journal of Physiology – Lung Cellular and Molecular Physiology — but in the latter case, the discrepancies don’t affect the conclusion.
Potts-Kant was arrested on embezzlement charges in 2013. Authorities alleged that she stole almost $15,000 from Duke University.
Environmental Health Perspectives posted a retraction in July, for a 2012 paper that looked at the molecular underpinnings in airways that react to ozone.
Here’s the full notice:

Noriyuki Takai, a gynecologic cancer researcher at Oita University in Japan, has lost another five papers. With a new total of 13, that means he’s now on our leaderboard.
Three of the retractions are from the journal Tumor Biology, one is from the International Journal of Gynecological Cancer, and one from Anticancer Research.
Takai is the first author on all 5 papers.
As has been the case with Takai’s retractions, and there’s evidence that all were felled by issues with figures. In all, according to the retraction notices, “original data were processed inappropriately.” Four end with the following sentence (or some close variation thereof):
