When we first wrote about Naoki Mori last December, one question we had was why Infection and Immunity, the journal that got the ball rolling in this case, wasn’t retracting a 1999 article by the serial manipulator. Well, it has.
The August issue of the journal, a publication of the American Society of Microbiology — which levied a 10-year ban on Mori for his misdeeds — contains the following retraction notice: Continue reading Another for Mori: 1999 Infection and Immunity paper pulled
Here’s a good way to increase the number of times your work is cited: Publish studies three times.
On second (or third) thought, maybe not: The Journal of Steroid Biochemistry & Molecular Biology has retracted a pair of articles by three Japanese researchers who apparently liked their own work so much they decided to submit it, and submit it—and submit it again.
Here’s the notice for the first paper, a 2004 publication titled “Vitamin D receptor (VDR) promoter targeting through a novel chromatin remodeling complex,” by Shigeaki Kato, Ryoji Fujiki and Hirochika Kitagawa, fairly well-known molecular endocrinologists at the University of Tokyo: Continue reading The new math: How to up your citations (hint: duplication). Plus a correction for Naoki Mori
We have updates on the two mysterious Journal of Neuroscience retractions we reported on yesterday. One is that we have learned that there is a university investigation into the work of one of the teams that retracted one of the studies. More on that in a bit.
Two, the journal’s editor, John Maunsell, responded to our request for comment, and we’re quoting his entire email (with annotation) because we think it raises important issues: Continue reading Update on Journal of Neuroscience retractions: Authors being investigated. Plus, editor explains why notices say nothing
The June 8 issue of the Journal of Neuroscience includes two retractions:
The notices are completely uninformative. They read: Continue reading Journal of Neuroscience retracts two, one 13 years old
Lest readers of Retraction Watch had forgotten about Naoki Mori, the cancer researcher who liked his Western blots so much he decided to reuse them — and reuse them some more — he’s back.
The British Journal of Haematology (BJH) has retracted two papers Mori published in that journal, and BMC Microbiology has retracted another, bringing the total of retractions involving his work to at least 19 by our count. [See update at end.]
The BJH issued both retractions online in the end of February, and they’ve since come out in print. Here’s the retraction notice for the first paper, in the BJH (first only because it was published first): Continue reading Three more withdrawals for Naoki Mori, and a hint of the mother of retractions
If a paper that has never been cited is retracted, will it be missed?
Japanese researchers have retracted an obscure 1996 article in an equally obscure physics journal after concluding — some 15 years later — that their fundamental assertion was mistaken.
The paper, “Uptake and excretion of cobalt in the crustacean Portunus trituberculatus,” in Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, purported to show that a form of the element cobalt might be helpful in tracing the growth of Portunus trituberculatus, otherwise known as the blue crab.
That’s the world’s most harvested crab species and a particular favorite in Asia. But don’t confuse it with the Chesapeake Bay blue crab, Callinectes sapidus, of William Warner’s Pulitzer Prize-winning book, Beautiful Swimmers.
The problem with such elemental tracers, it seems, is that crabs moult repeatedly, shedding their shells, along with the elements that build up inside them. According to researchers from the Research Institute for Advanced Science and Technology and the Osaka Prefectural Fisheries Experimental Station, however, a volatile form of cobalt, previously undetected, could be a suitable element for tracing the growth of both crabs and prawns — another important aquaculture species in Asia — over time.
But that turned out to be a (shell)fish tale. Per the retraction notice, which appears in the May 15, 2011 issue of the journal: Continue reading Another unofficial record? Authors walk back arcane blue crab paper — 15 years later
There’s helpful but uninformative:
Ivan: What’s the weather like today?
Adam: Sunny.
And then there’s uninformative as served up by the Journal of Biological Chemistry.
We’ve already recounted one teeth-grinding experience with the JBC, a publication of the American Society for Biochemistry and Molecular Biology. The case involved two papers in JBC by Axel Ullrich, an esteemed cancer researcher at the Max Planck Institute in Germany. According to Ullrich, one of his then-postdocs, Naohito Aoki, had manipulated figures that appeared in the papers, necessitating their retraction.
Round two involves another JBC retraction of a 2000 paper by Aoki and co-author Tsukasa Matsuda, titled ‘A cytosolic protein-tyrosine phosphatase PTP1B specifically dephosphorylates and deactivates prolactin-activated STAT5a and STAT5b.’ The paper has been cited more than 100 times, according to Thomson Scientific’s Web of Knowledge.
According to the notice: Continue reading Freedom from Information Act? Another JBC retraction untarnished by any facts
Naoki Mori, of 16-retraction fame, believes he’s getting his job back at the University of the Ryukyus, which released him in August after learning that the cancer researcher had misused images in many of his publications.
According to a report in Science Insider, Mori’s penalty has been reduced to a 10-month suspension, and he will resume his professorship in June. Mori apparently also told Science that some journals “are considering accepting corrected papers,” although he didn’t name them. Continue reading Naoki Mori, with 16 retractions, to be rehired?
There’s parsing a-plenty in the American Journal of Physiology Lung Cellular and Molecular Physiology this month. The journal has retracted a 2010 paper by researchers at Chiba University in Japan, who lifted much of their manuscript from an article by other scientists in a different publication.
The authors of the paper, “The estrogen paradox in pulmonary arterial hypertension,” confess that they misappropriated text. But how they do so is a case study in subtlety: Continue reading Plagiarism and other ‘negligence’ fell lung-estrogen paper
Biochemical Journal has retracted two articles by Naoki Mori, bringing the total number of pulled papers by the Japanese cancer researcher to sixteen.
As with the previous Mori retractions, the latest ones — of papers published in 2007 and 2010 — involve unreliable images. Mori, you’ll recall, had recycled control blots from study to study over the years, and was dismissed from his academic post in August.
The 2007 paper, “Activation of hypoxia-inducible factor 1 in human T-cell leukaemia virus type 1-infected cell lines and primary adult T-cell leukaemia cells,” also included a frequent co-author Mariko Tomita, who has been implicated in the deception. It has been cited 15 times, according to Thomson Scientific’s Web of Knowledge. The 2010 article, “Inhibition of Akt/GSK3β signalling pathway by Legionella pneumophila is involved in induction of T-cell apoptosis,” has not yet been cited.
In each case, the retraction notice is the same: Continue reading Two more retractions for Mori make 16 — but not a record
