What Caught Our Attention: The researchers were studying how curcumin, a component of the spice turmeric, can inhibit lung cancer metastases. But upon learning that the primary material had been expired at the time of testing (and realizing they were unable to repeat their experiments), the researchers pulled their paper. Expiration dates do have safety factors built in, but attention to such details is imperative in research.

After publication of this article, the corresponding author, Qing-yong Chen, notified the editorial office that the curcumin used in this study was expired at the time of use. The authors expressed concern that this may have affected the results of the MTT assays and microarray expression experiments reported in the article; they are unable to repeat the experiments at this time. Due to concerns about the validity of the data and results reported in this work, the authors and the PLOS ONE Editors retract this article.
