Stem cell researcher Jacob Hanna’s correction count updated to 10

Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.

The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.

First up, a correction to a Cell paper on which Hanna is the first author:

NSF investigation of high-profile plant retractions ends in two debarments

A nearly ten-year-long series of investigations into a pair of plant physiologists who received millions in funding from the U.S. National Science Foundation has resulted in debarments of less than two years for each of the researchers.

The NSF Office of Inspector General recently posted its close-out report on its decision and a review of the University’s investigation, which had recommended a total of eight retractions or corrections. Although the investigator’s names have been redacted, the text of retractions and corrections quoted in the report corresponds to papers by Continue reading NSF investigation of high-profile plant retractions ends in two debarments

Investigation of prominent geneticist Latchman finds “procedural matters,” no misconduct

David Latchman, Birkbeck

An investigation by the University College London has cleared prominent geneticist David Latchman of misconduct, but concluded he has “procedural matters in his lab that required attention.”

Latchman has two retracted papers; on PubPeer, there are questions about nearly four dozen more.

The results of the investigation were first reported by the Times Higher Education. We also received a short statement from a UCL spokesperson:

Three retractions for Oregon neuroscience student investigated by ORI

xhp-150

Journals have retracted three out of the four papers flagged by the Office of Research Integrity during its investigation of a University of Oregon neuroscience student, David Anderson.

Last month, when we first reported on the case, Anderson told us that he “made an error in judgment,” and took “full responsibility.” Two of the retraction notes say that Anderson “knowingly falsified data,” and cited the Office of Research Integrity case summary.

All three papers focus on memory.

The note for the first retraction, from the  Journal of Experimental Psychology: Human Perception and Performance, reveals exactly how Anderson falsified data in the paper. It’s paywalled — tsk, tsk — but printed here in full:

Researchers suspended in Japan for funding violations

Hokkaido University has suspended two of its professors after an investigation found “improper receipt of research funding.”

One member of the team was awarded more than 15 million yen (roughly $120,000 USD) in research grants from the Japan Society for the Promotion of Science (JSPS), according to the official statement (translated by One Hour Translation).

The researchers share a last name. Hiroyoshi Ariga, a professor of Biomedical and Pharmaceutical Science and the head of a university lab, was given 8 million yen in 2006 and 7.5 million in 2007. It appears that Sanae Ariga also received funds for a similar study, based on the translation:

First author refuses to sign PNAS retraction after “key findings” are not reproduced

33.cover

Two out of the three authors of a PNAS paper on mutations underlying lung diseases are pulling it after failing to reproduce key findings.

The paper, published in 2012, investigated how mutations in lung surfactant genes induce molecular changes that lead to lung pulmonary fibrosis and lung cancer might work. But follow-up work revealed problems. In the retraction note, last author Christine Kim Garcia and second author Christoper Cano, both at the University of Texas Southwestern Medical Center, write:

Current members of the C.K.G. laboratory are unable to reproduce key findings reported in the paper.

Here’s the retraction note in full:

Former UCSF grad student fudged data in two papers

ORIA former graduate student at the University of California, San Francisco “knowingly falsified and/or fabricated” data in two published papers, according to the Office of Research Integrity.

According to a case summary published this morning, Peter Littlefield was working on his PhD, studying the ways that cells respond to external signals, when he published the two problematic papers. He is the first author on the papers; Natalia Jura, whose lab he worked in, is the last on both.

The report’s findings are based on, among other sources, “the respondent’s admission.”

The first paper, “Structural analysis of the EGFR/HER3 heterodimer reveals the molecular basis for activating HER3 mutations” was published in Science Signaling and has been cited twice, according to Thomson Scientific’s Web of Knowledge.

Three figures in the paper are problematic, says the ORI summary:

Investigation digs up data falsification in two papers on roundworm stress

18.coverAn investigation at the University of Florida has led to the retraction of a pair of papers on the stress responses of Caenorhabditis elegans in Molecular and Cellular Biology.

One paper has been retracted, and one “partially” retracted, as the main conclusion was “not compromised.” According to the retraction notes, the investigation found the data were “falsified” by first author Chi Leung, a former postdoc at UF.

Here’s the note in full for the partial retraction of “A Negative-Feedback Loop between the Detoxification/Antioxidant Response Factor SKN-1 and Its Repressor WDR-23 Matches Organism Needs with Environmental Conditions:”

A correction to a correction for stem cell researcher Jacob Hanna

A correction to a correction is the latest problem for highly cited researcher Jacob Hanna. The stem cell scientist — whose high-profile work has received scrutiny over the past year — has amended an earlier correction notice after a reader spotted an inadvertent “mistake.”

We reported on the original correction, to the 2009 Cell Stem Cell paper “Metastable Pluripotent States in NOD-Mouse-Derived ESCs,” in July. The paper has been cited 184 times, according to Thomson Scientific’s Web of Knowledge.

Apparently, a pair of images in the original correction note are of the same cell colonies, when they are supposed to be of separate cell colonies.

The new (and detailed) note explains how that happened:

EMBO investigation yields two more retractions and three corrections for Voinnet

An investigation into the work of Olivier Voinnet by The EMBO Journal has led to another two retractions and three more corrections for the high-profile plant scientist, now suspended from the CNRS for two years.

According to the authors, Voinnet was responsible for some of the errors; all papers have been questioned on PubPeer.

The EMBO J, the flagship publication of the European Molecular Biology Organization, posted four notices earlier today and told Retraction Watch that the notice for the fifth paper would be posted by tomorrow.

This latest round brings our count for Voinnet up to Continue reading EMBO investigation yields two more retractions and three corrections for Voinnet
