leave a comment »

ChemosphereElsevier journal Chemosphere may finally retract a paper it learned contained fabricated data in January when a member of the author’s institution requested the paper be retracted.

The paper has been cited at least once since the lies came to light, as we reported earlier this month.

The journal contacted the relevant parties on October 29 with the following email about “Degradation of 2,4-dinitroanisole (DNAN) by metabolic cooperative activity of Pseudomonas sp. strain FK357andRhodococcus imtechensis strain RKJ300,” although no notice has been posted: Read the rest of this entry »

Obviously, mistakenly studying the wrong kind of cancer is a waste of precious resources, both time and money. And it’s clear the problem hasn’t gone away. PLoS ONE just retracted a cancer paper originally published in December 2012 for studying two cell lines that had been contaminated by other cell types.
