What Caught Our Attention: Here’s a cut-and-paste issue that gave us pause. The authors of an 18-year-old paper in PNAS corrected it after realizing some bands in a figure were duplicated (an issue raised on PubPeer one year ago). It turns out, the first author had cut the paper into pieces and reassembled them to present the blots in the “desired order,” and some had become duplicated by mistake. The overall results were unaffected, so the journal swapped the image with a corrected version.

The authors wish to note the following: “Recently when we analyzed Fig. 4B (a Western blot visualizing the yeast protein Leu1), we noticed that there was an error in the assembly of the bands. Because the gel loading for the Western blot did not fit the desired order for presenting the data, the first author cut the thermoprinter paper printout into pieces and reassembled them. Unfortunately, the published version contained an unintentional data duplication (mirrored bands for the 64 h data points), but the overall results were not impacted. We apologize for the mistake.” The corrected Fig. 4 and its legend appear below.
