A paper about eye damage in astronauts got pulled for “security concerns.” Huh?

with 13 comments

Here’s a head-scratcher: A 2017 paper examining why long space flights can cause eye damage has been taken down, with a brief note saying NASA, which sponsored the research, asked for the retraction because of “security concerns.”

According to the first author, the paper included information that could identify some of the astronauts that took part in the study — namely, their flight information. Although the author said he removed the identifying information after the paper was online, NASA still opted to retract it. But a spokesperson at NASA told us the agency did not supply the language for the retraction notice. The journal editor confirmed the paper was retracted for “research subject confidentiality issues,” but referred a question about who supplied the language of the notice back to NASA.

Now lawyers are involved.

So we still have some questions about this one. Here’s what we do know.

Opaque retraction notice for imaging paper

with 2 comments

cmmmSometimes we run across retraction notices that are vague, and others that are contorted, but we’ve just found one that gets highest marks for being completely inscrutable.

The article, “Bayes Clustering and Structural Support Vector Machines for Segmentation of Carotid Artery Plaques in Multicontrast MRI,” was written by a group from China and Cambridge University in England — so, we’re thinking language ought not to have been much of a barrier to clear English. It appeared in November 2012 in Computational and Mathematical Methods in Medicine, and describes a way to analyze carotid artery plaque levels in MRI images.

But according to the notice, the technique did not work as planned (or so we think):

Retraction, tell-all style, for breast cancer radiology paper

with 5 comments

acta radHere at Retraction Watch, we don’t believe in the expression “TMI.” But this case features a level of detail we’re not sure we’ve seen before.

Acta Radiologica has pulled a 2012 article on breast cancer imaging for being a duplicate publication — a sin the retraction notice takes great pains to point out.

The notice, written by journal editor Arnulf Skjennald, has the blow-by-blow feel of a police report: Read the rest of this entry »

cureusBenjamin Jacob Hayempour, the researcher who threatened to sue us for asking questions about a retraction for plagiarism, has had another paper withdrawn.

The paper, published online in the journal Cureus, was titled “Novel Determinants of Tumour Radiosensitivity Post-Large-Scale Compound Library Screening” and had been available at since January 13, but that URL now redirects to Cureus’s homepage.

We asked Cureus editor-in-chief John Adler for details, and he responded: Read the rest of this entry »
