Editor on retraction details: “I do not think this is the business of anyone but our journal, please”

with 7 comments

early education developmentWhose business are the reasons behind a retraction?

Our readers will no doubt know by now that we think they’re basically everyone’s — at least if journals want us to believe that they’re interested in maintaining the integrity of the scientific record. But not all editors seem to agree. Hank Edmunds, for example, didn’t in early 2011, telling us, “It’s none of your damn business.” A chemistry journal editor said, in a similar vein, “the purpose of keeping these retraction notices slim is not to produce too much detail.”

Now, a psychology journal editor joins those ranks. Here’s the notice in question: Read the rest of this entry »

Plague paper partially retracted

with 2 comments

iandi213coverPartial retractions — as opposed corrections or the full monty —  are unusual events in scientific publishing. But they appear to come in twos.

The journal Infection and Immunity, the work of whose editor, Ferric Fang, is much admired by this blog, has a fascinating example of the breed in its February issue.

The article in question, by a group from the University of Kentucky in Lexington led by Susan Straley, appeared online in 2007. It was titled “yadBC of Yersinia pestis, a New Virulence Determinant for Bubonic Plague,” and, as the words suggest, involved a gene marker for the virulence of plague. Or so it initially seemed.

But according to the partial retraction, the researchers are walking back one of their main claims. Consider: Read the rest of this entry »

Scientists retract paper because they’re “not satisfied with the quality of some of the data”

with 27 comments

antiox and redoxA group of smoking researchers — no, not scientists who are on fire; scientists who study the effects of tobacco smoke — has retracted a 2009 article after deciding that they were no longer “satisfied with the quality of the data.”

The paper, “Cigarette Smoke–induced Oxidative/Nitrosative Stress Impairs VEGF- and Fluid Shear Stress–Mediated Signaling in Endothelial Cells,” came from the lab of Irfan Rahman, a lung disease expert at the University of Rochester. It appeared online in 2009 in Antioxidants & Redox Signaling, which will be familiar to readers watching the case of Dipak Das
