Rabbits needn’t worry about cell phones’ effects on their sperm count, say three retractions

If you’re a rabbit and you haven’t figured out where to carry your cell phone, your front pocket is just fine.

That’s what you could reasonably infer from the retraction of a paper in the International Journal of Andrology purporting to show that mobile phones affected rabbits’ sperm counts. The notice, signed by the journal’s editor, Ewa Rajpert-De Meyts (we added links): Continue reading Rabbits needn’t worry about cell phones’ effects on their sperm count, say three retractions

PNAS author explains why she didn’t sign retraction notice for potential anti-cancer drug study

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.

First, a comment from lead author Paul W.H.I Parren, who tells Retraction Watch: Continue reading PNAS author explains why she didn’t sign retraction notice for potential anti-cancer drug study

Paper linking vitamin C and reduced asthma retracted after authors find “severe” problems with data

It’s never a good sign when a paper has “severe” problems with its data. But when even the researchers are at a loss to explain how those problems made their way into the manuscript, well, that’s downright alarming.

Consider: The journal Clinical and Translational Allergy has retracted a 2011 article by researchers from Egypt and Finland, who have been studying the effects of vitamin C on childhood asthma. In a previous article, published in 2009 in Acta Paediatrica, members of the team reported that Continue reading Paper linking vitamin C and reduced asthma retracted after authors find “severe” problems with data

Redox, redux: Journal pulls paper over data problems

Antioxidants & Redox Signalling has issued much more detailed retraction notice for a paper it pulled last year that was marred by duplicate data.

As we reported then, the journal’s initial notice for the 2011 article, titled “Inhibition of LXRa-dependent steatosis and oxidative injury by liquiritigenin, a licorice flavonoid, as mediated with Nrf2 activation,” was underwhelming:

THIS WORK HAS BEEN RETRACTED BY THE AUTHORS

Although we learned at the time that a reader, Paul Brookes, of the University of Rochester, had raised concerns about the article to the editors of ARS and other publications, we were glad to see that ARS has decided to make a clean breast of matters. The study has been cited by other papers three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, from editor Chandan K. Sen: Continue reading Redox, redux: Journal pulls paper over data problems

Another non-unanimous PNAS retraction, for potential anti-cancer drug, after company’s method proves unreliable

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.

According to the notice for “The antibody zalutumumab inhibits epidermal growth factor receptor signaling by limiting intra- and intermolecular flexibility:” Continue reading Another non-unanimous PNAS retraction, for potential anti-cancer drug, after company’s method proves unreliable

Authors retract paper claiming antidepressants prevent suicide

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.

The original paper linked “data on the toxicological detection of antidepressants in 18 922 suicides in Sweden 1992–2003” to “registers of psychiatric hospitalization as well as registers with sociodemographic data.” It found: Continue reading Authors retract paper claiming antidepressants prevent suicide

Watch and learn, science journals: “This American Life” retracts Mike Daisey segment on Apple in China

“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 non-unanimous retraction in PNAS after authors are “unable to reproduce the data”

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.

According to the notice for the paper, which has been cited 8 times, according to Thomson Scientific’s Web of Knowledge: Continue reading A non-unanimous retraction in PNAS after authors are “unable to reproduce the data”

Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.

Journal editor James Seiber writes: Continue reading Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

Journal pulls four breast cancer papers for duplication

The journal Breast Cancer: Targets and Therapy, a Dove Medical Press title, has retracted four articles from a group of Indian researchers over what it said were “unacceptable levels” of duplication with other published work. (Such a construction leaves us wondering what might constitute “acceptable levels” of duplication, but that’s for a different post.)

The articles were submitted by Rajeev Singhai, who is listed as being with Grant Medical College and the Sir J J Group of Hospitals, in Mumbai. According to his After College page, Singhai received his PhD in 2011 and is now a research fellow.

As the notice states: Continue reading Journal pulls four breast cancer papers for duplication
