At a snail’s pace: Species rediscovered, but paper on its disappearance remains

biology lettersA few weeks ago, in Weekend Reads, we highlighted the story of a snail species, thought to have gone extinct thanks to global warming, that had been rediscovered.

Now, as first reported by The Scientist, the journal in question has addressed the issue.

Here’s the story: In 2007, Biology Letters published a paper by Justin Gerlach describing the extinction of the Aldabra banded snail. But as journal editor Richard Battarbee notes: Continue reading At a snail’s pace: Species rediscovered, but paper on its disappearance remains

A cancer paper was retracted on September 17 for a double publication. According to the notice in which the authors admit to duplicating the “opening to the readers,” which we assume is the introduction, there was no need to cite the article “because it had not yet been printed at that time.”

Here’s the notice for “The effect of HER-2 polymorphism according to age on the risk and pathologic feature of endometrial cancer”: Continue reading Authors retract HER-2 endometrial cancer paper for 2x publication

“Several scientific errors” sink physics paper after rewrite opportunity

canadian journal of physicsWe don’t love this somewhat incoherent retraction for a paper on coherent states, although luckily the publisher was prompt with telling us a little more about what happened.

On October 2, a 2008 physics paper, “Generation of a superposition of coherent states in a resonant cavity and its nonclassicality and decoherence,” was retracted for “several scientific errors,” pointed out by a comment published in the same journal. The original authors rewrote the paper, but it was not up to the standards of Canadian Journal of Physics, so it was rejected, and the original was retracted.

Here’s the notice: Continue reading “Several scientific errors” sink physics paper after rewrite opportunity
