Frank Sauer, formerly of the University of California, Riverside, has had a 2002 letter on epigenetics retracted from Nature due to “inappropriate image manipulation.”
Sauer had two papers retracted from Science last year following a university investigation. Here’s the Nature notice for “Histone methylation by the Drosophila epigenetic transcriptional regulator Ash1:” Continue reading Nature retracts epigenetics paper by author who lost two Science papers last year
Noriyuki Takai, a gynecologic cancer researcher in Japan, has notched one more retraction — bringing the total to eight — due to figures that were “processed inappropriately” and did “not accurately report the original data.”
According to the notice, Takai alone put the figures together in the 2006 Oncology paper, which tested a histone deacetylase inhibitor on endometrial and ovarian cancer cell lines. The team is part of the department of obstetrics and gynecology at Oita University in Japan.
Takai lost four papers in 2013 in Cancer Letters, and three papers in 2012 in Gynecologic Oncology, also due to issues with figures.

An expression of concern has been published on a paper that taps into a decades-long fight over how to remove lead from the water supply.
The paper in question, published in the Journal American Water Works Association, supports the safety of a common but frequently criticized way of incrementally removing lead pipes. The expression of concern came after years of back-and-forth letters to the editor between other scientists and the authors.
Lead water pipes have been causing lead poisoning for generations; some people have even theorized that the ancient Romans’ use of the metal facilitated the empire’s downfall. The dangers of childhood exposure to lead — delayed development, irreversible damage to the brain and nervous system and behavioral problems — have been documented in the U.S. since the 1940s, but the Environmental Protection Agency didn’t start regulating lead levels in drinking water until 1991, when the “lead and copper rule” went into effect. That set the standard for utility companies’ lead testing: if 10 percent or more of samples from homes had lead levels above 15 parts per billion, the companies were required to replace 7% of their lead pipes a year until they met the requirements.

Chemists at Lanzhou University in China did the right thing last month, retracting a paper in Advanced Synthesis & Catalysis because of issues with a reactant that could only be corrected by changing “all the text and quantities.”
When the scientists were adding what was labeled Reactant 1 to the mix, they believed it was α-ethoxycarbonyl-α-azido-N-phenylacetamides. Unfortunately, what they were actually using was a decomposed version of the molecule, which threw everything off.
Here’s the notice for “tert-Butyl Hydroperoxide and Tetrabutylammonium Iodide- Promoted Free Radical Cyclization of α-Azido-N-arylamides”: Continue reading Molecular mixup burns chemistry paper
A paper on the genetics of mythical creatures — yeti and bigfoot — is being corrected after the journal discovered the first author, Bryan Sykes, listed a mythical institution.
The Proceedings of the Royal Society B paper, “Genetic analysis of hair samples attributed to yeti, bigfoot and other anomalous primates,” examined 30 samples from “museum and individual collections” that had been labeled as the North American bigfoot, Tibetan yeti, Mongolian almasty, and Sumatran orang pendek. The analysis showed the samples actually came from a variety of species, such as bears, horses, and cows. Perhaps the most striking is the paper’s claim that two samples match with a prehistoric polar bear, “but not to modern examples of the species.”
Reading is hard and takes a long time, so it’s nice that the Iron and Steel Institute of Japan didn’t give us too much work to do with this 12 word retraction.
Journal ISIJ International minced no words about why the 2014 paper on steel manufacturing was withdrawn, because there were no words. Here’s the notice for “Microstructure and Properties of Fiber Laser Welded Joints of Ultrahigh-strength Steel 22MnB5 and its Dissimilar Combination with Q235 Steel” in its entirety – half the length of the title!: Continue reading Retraction notice for steel manufacturing paper leaves much to the imagination
A paper on wiretapping in the Arab region has been retracted by a Qatari law review journal for redundant publication and “possible misuse of plagiarism detection software at the authoring stage.”
The 2013 article in the International Review of Law discusses how different Arab countries regulate intercepting telecommunications, and how to balance public safety with the right to privacy. According to the notice, it ripped off two other articles by author Nazzal Kisswani, published in 2011 and 2010. “Although it is not an exact copy of a previously published article, it contains parts of it,” the retraction explains.
Here’s the notice for “The “Right to Privacy” v. telecommunications interception and access: International regulations and implementations in the Arab Region”: Continue reading “Identical in theory and concept”: Privacy paper pulled over redundancy
Karel Bezouška, the Czech biochemist who was caught on hidden camera breaking into a lab fridge to fake results, has turned it up to eleven with two new retractions.
Both retractions appeared in Biochemical and Biophysical Research Communications, one in October 2014 and one in January 2015. His story began two decades ago in 1994, when he published a paper in Nature that couldn’t be reproduced, and was eventually retracted in 2013.
The best part of the story, of course, is that when his university was attempting to recreate his experiments, Bezouška broke into a lab fridge to tamper with the experiments. Unbeknownst to him, he was caught on hidden camera. Continue reading Two more retractions bring lab break-in biochemist up to eleven
A 2002 paper has been retracted by Cancer after some of the authors notified the journal that they hadn’t agreed to submit it — and an investigation found that a number of the patients described had been made up.
Here’s the notice for “Radioimmunotherapy of small-volume disease of metastatic colorectal cancer: results of a phase II trial with the iodine-131–labeled humanized anti–carcinoembryonic antigen antibody hMN-14:” Continue reading Study by deceased award-winning cancer researcher retracted because some patients were “invented”
It turns out a 2014 paper that found a surprising pattern of plant migration in response to global warming was not so surprising after all — it’s been retracted by the authors due to a mistake in the statistical analysis.
Most studies on migrating populations have found that species around the globe move north to escape the rising temperatures. But the authors of the 2014 paper in Global Change Biology found the opposite — according to their analysis, many plant species in Western North America had been migrating south, toward warmer climates.
The lead author Melanie Harsch told Science in 2014 that the team had been suspicious of the analysis, and so ran it twice: Continue reading Stats error has chilling effect on global warming paper
