After five years of operation, the Nature Publishing Group is will no longer accept submissions to its preprint server Nature Precedings, having found the experiment “unsustainable as it was originally conceived.”
The two Free Radical Biology & Medicine retractions, for “Expression of the longevity proteins by both red and white wines and their cardioprotective components, resveratrol, tyrosol, and hydroxytyrosol” (cited 38 times, according to Thomson Scientific’s Web of Knowledge) and “Redox regulation of resveratrol-mediated switching of death signal into survival signal” (cited 32 times), are carefully detailed and read the same way: Continue reading Three more retractions for resveratrol researcher Dipak Das, in free radical journals
We have an update in the case of two Japanese scientists who first came to our attention when they retracted a 13-year-old paper in the Journal of Neuroscience last year. Shortly after that, we learned, thanks to a report in Sankei Shimbun and a helpful Retraction Watch reader, that some 17 papers were being investigated.
It now appears that 19 papers by the two researchers, Kenji Okajima and Naoki Harada, ended up under scrutiny.
Nagoya City University said last week that their investigation had concluded that Okajima and Harada committed misconduct. The university dismissed Harada, whom they found guilty of misconduct in at least eight of the papers. The investigation couldn’t find any evidence that Okajima was directly involved, but suspended him for six months because he supervised the work. Continue reading Japanese universities find pair of researchers guilty of misconduct in 19 papers
On Tuesday, we covered a retraction in the Proceedings of the National Academy of Sciences (PNAS) involving zalutumumab, a compound once being developed for treatments of head and neck cancer. As we noted at the time, the authors decided to retract the paper because they no longer trusted the method they used. One of the authors didn’t sign the notice, and we’ve now heard from her about why.
There’s another non-unanimous retraction in the Proceedings of the National Academy of Sciences (PNAS) this week, and this one involves an anti-tumor antibody that may not be what the authors originally thought it was.
The authors of a study allegedly showing that antidepressants prevent suicide have retracted it over unspecified errors. Here’s the notice:
At the request of the authors and in agreement with the Editor-in-Chief and Wiley-Blackwell, the following article “Antidepressant medication prevents suicide in depression”. Acta Psychiatr Scand 2010;122:454–460 has been retracted. The retraction has been requested and agreed due to unintentional errors in the analysis of the data presented.
“This American Life,” the popular radio show hosted by Ira Glass, is retracting an episode in which monologist Mike Daisey claimed to have described conditions in a Chinese factory that makes electronic devices, including Apple products. According to a note about this week’s episode:
Regrettably, we have discovered that one of our most popular episodes was partially fabricated. This week, we devote the entire hour to detailing the errors in “Mr. Daisey Goes to the Apple Factory,” Mike Daisey’s story about visiting Foxconn, an Apple supplier factory in China. Rob Schmitz, a reporter for Marketplace, raises doubts on much of Daisey’s story.
Ira also talks with Mike Daisey about why he misled This American Life during the fact-checking process. And we end the show separating fact from fiction, when it comes to Apple’s manufacturing practices in China.
A This American Life press release spells out why the show retracted the segment, and it isn’t pretty. The doubts started with Rob Schmitz, who interviewed Daisey’s Chinese interpreter, Li Guifen. (She goes by Cathy Lee professionally with Westerners, according to the release.) A lot of what Daisey had attributed to Lee was false, she said. And that came on top of the fact that Daisey had told This American Life fact-checkers that Lee’s name was Anna, and that he didn’t have a way to reach her anymore. Glass is quoted in the press release: Continue reading Watch and learn, science journals: “This American Life” retracts Mike Daisey segment on Apple in China
A group of authors has retracted a 2009 paper in the Proceedings of the National Academy of Sciences (PNAS) after subsequent experiments suggested their original results weren’t holding up.
