Here’s the retraction notice for “Slug enhances invasion ability of pancreatic cancer cells through upregulation of matrix metalloproteinase-9 and actin cytoskeleton remodeling,” by Liqun Wu and colleagues of The Affiliated Hospital of Medical College, QingDao University, in China’s Shan Dong Province: Read the rest of this entry »
Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road.
The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab of Manuel Llinás. It purported to find that:
It turns out that wasn’t the only problem with the article — but we’re afraid that the glitch requires us to issue a correction.
The article, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” has listed Aaron Danner as the last — and, we’d assumed — senior author of the paper. But as Danner pointed out to us, that was a mistake by Nature Photonics.
The authors of a paper in Nature Photonics have been forced to walk back their article after learning from another group of researchers that their conclusions likely were an, ahem, optical illusion.
The paper, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” appeared in January 2012 and came from a team
led by that included Aaron Danner, an optics expert at the National University of Singapore. As the abstract of the paper explains (to physicists, anyway):
Two retractions for scientist whose work is “not fully supported by the available laboratory records”
The head of immunology at India’s Centre for DNA Fingerprinting and Diagnostics, Sunil Kumar Manna, has retracted two papers for image problems.
Here’s the notice from Cell Death and Differentiation for “Inhibition of RelA phosphorylation sensitizes apoptosis in constitutive NF-kappaB-expressing and chemoresistant cells:” Read the rest of this entry »
The authors of a study published last year looking at the effects of cell phone exposure on mice in utero have corrected a figure after it was questioned. New experiments, they write, confirm the original conclusions they drew from the figure.
The article, “Promoter hypomethylation of the LINE-1 retrotransposable elements activates sense/antisense transcription and marks the progression of chronic myeloid leukemia,” was published online in September 2005 and has been cited 106 times, according to Thomson Scientific’s Web of Knowledge.
Last month, we brought you news that Pfizer had retracted a paper in the Journal of Clinical Oncology
purporting to show a benefit of their experimental drug for lung cancer figitumumab after discovering that its clinical lead on the project had done analyses improperly.
There’s been another retraction, of a related paper, in the British Journal of Cancer, “Pre-treatment levels of circulating free IGF-1 identify NSCLC patients who derive clinical benefit from figitumumab.” Here’s the notice: Read the rest of this entry »
In baseball, it’s three strikes and you’re out. In Nature, apparently, you can stay at the plate after three swings-and-misses.
That’s what we concluded from a Corrigendum in last week’s issue, for “CD95 promotes tumour growth,” originally published in May 2010 and now corrected not once, not twice, but three times.
