The National University of Singapore (NUS) is reviewing about 70 papers by Alirio Melendez, a once-promising researcher whom, as we’ve reported, has been forced to retract a paper in Nature Immunology and has another paper in Science subject to an Expression of Concern.
The Straits Times, which reported the NUS investigation this weekend, says Melendez’ former team is cooperating:
In Singapore, the eight researchers involved include scientists, academics, research fellows and students from NUS and DSO National Laboratories. DSO and the personnel involved are assisting the university in its investigation.

The retraction total for Naoki Mori continues to rise.
The October issue of Biochemical and Biophysical Research Communications has retracted a 2007 paper by Mori et al for the same issues — manipulated images — that brought down the 20-odd other papers of his since the scandal broke in late December.
Here’s the notice for the pulled paper, titled “Downregulation of citrin, a mitochondrial AGC, is associated with apoptosis of hepatocytes:” Continue reading Another retraction for Naoki Mori (make that 23?)
Believe it or not, we look for policies to praise here at Retraction Watch HQ, especially if they mark a change from approaches that we and others have criticized. So we were heartened to read this retraction notice in The Journal of Neuroscience for “Lmx1b-Controlled Isthmic Organizer Is Essential for Development of Midbrain Dopaminergic Neurons:”
The Journal of Neuroscience has received a report describing an investigation by the Shanghai Institute of Biological Sciences, Chinese Academy of Sciences, which found major data misrepresentation in the article by Guo et al. Because the results cannot be considered reliable, The Journal is retracting the paper.
The study has been cited five times since it was published in 2008, according to Thomson Scientific’s Web of Knowledge. Here’s some background on why we thought we’d have something to praise, from a Nature feature this week on retractions: Continue reading Does a new retraction suggest a glimmer of hope for transparency at the Journal of Neuroscience?
Talk about a career-killer. The following retraction, from Genetics and Molecular Research, an online journal, spares nothing in its evisceration of an unfortunate graduate student who compiled an impressive list of transgressions in a single manuscript.
The 2010 article, titled “Genetics and biochemical analyses of sensor kinase A in Bacillus subtilis sporulation,” came from the lab of Masaya Fujita at the University of Houston. The first author was a now-former graduate student named Jean-Calvin Nguele. Whether the title is accurate, we can’t say, but apparently not much else was.
One of the themes we’ve hit hard here at Retraction Watch is that there is tremendous variation in how journals deal with retractions. Some make notices crystal clear, while others seem to want to make them as opaque as possible. Some editors go out of their way to publicize withdrawals, while others bury them and won’t talk about them when they appear.
In a Nature feature out today on retractions, Richard van Noorden highlights those disparities. He also highlights the fact that there are more retractions to talk about: As a graphic accompanying the piece makes clear, retractions have risen 10-fold in the last decade, even as the number of papers published has grown by less than fifty percent.
But even with that growth, the number of retractions — we’re on track for 400 this year, according to Thomson Reuters — is a vanishingly small percentage of the 700,000 papers published annually. Still, science prides itself on transparency — or should, anyway. van Noorden gives Ivan the chance to offer some advice to those scientists and editors who are reluctant to acknowledge there’s ever any dirty laundry in science: Continue reading Do editors like talking about journals’ mistakes? Nature takes on retractions
“Clare Francis,” a prolific pseudonymous Retraction Watch tipster, emailed us recently to flag a retraction in the Journal of Steroid Biochemistry and Molecular Biology (JSBMB) of “The anti-inflammatory activity of 1,25-dihydroxyvitamin D3 in macrophages,” a paper by Amos Douvdevani and colleagues at Ben Gurion University in Israel.
Here’s what we found when we clicked on the notice for the 2007 paper, which has been cited 32 times, according to Thomson Scientific’s Web of Knowledge:
This article has been retracted at the request of the authors, in response to concerns raised by the research committee at the authors’ institution. The authors stated the committee had given approval but the committee states no approval was given. The research committee has asked the authors to retract the paper and the authors have agreed.
That sounded odd to us, since it was unclear what approval was needed, or hadn’t been given. Continue reading Mistaken notice as Ben Gurion researchers retract vitamin D paper for duplication
Scott Weber, the nursing researcher whose publishing misconduct has cost him posts at the University of Pittsburgh and Walden University, has been sanctioned by the Office of Research Integrity for his misdeeds.
Like many researchers, Frank Walboomers frequently checks the scientific databases to see when his latest publications appear. He was doing so a few months ago when he came across his name on an article — “Effects of pro-inflammatory cytokines on mineralization potential of rat dental pulp stem cells” — published online in July in the Journal of Tissue Engineering and Regenerative Medicine, that he hadn’t written.
The first author of the paper, Xuechao Yang, was a former doctoral student in Walboomers’ laboratory at Radboud University Nijmegen. It didn’t take Walboomers long to figure out what had happened: Continue reading “Ill communication” leads to retraction of tissue paper (sorry) for authorship issues
The Proceedings of the National Academy of Sciences (PNAS) has published the seventh retraction for former Duke researcher Anil Potti, who now faces a lawsuit in the midst of an ongoing investigation into his work:
Retraction for “A genomic approach to colon cancer risk stratification yields biologic insights into therapeutic opportunities,” by Katherine S. Garman, Chaitanya R. Acharya, Elena Edelman, Marian Grade, Jochen Gaedcke, Shivani Sud, William Barry, Anna Mae Diehl, Dawn Provenzale, Geoffrey S. Ginsburg, B. Michael Ghadimi, Thomas Ried, Joseph R. Nevins, Sayan Mukherjee, David Hsu, and Anil Potti, which appeared in issue 49, December 9, 2008, of Proc Natl Acad Sci USA (105:19432–19437; first published December 2, 2008; 10.1073/pnas.0806674105).
The authors wish to note the following: “We wish to retract this article because we have been unable to reproduce certain key experiments described in the paper regarding validation and use of the colon cancer prognostic signature. This includes the validation performed with dataset E-MEXP-1224, as reported in Fig. 2A, as well as the generation of prognostic scores for colon cancer cell lines, as reported in Fig. 4. Because these results are fundamental to the conclusions of the paper, the authors formally retract the paper. We deeply regret the impact of this action on the work of other investigators.”
The 2008 paper, which has been cited 27 times, according to Thomson Scientific’s Web of Knowledge, was already the subject of a minor 2009 correction: Continue reading New in PNAS: Potti retraction number seven, and a Potti correction
