paper retraction in absence of data
see copyrighted material here: http://science.sciencemag.org/content/357/6352/654.1 In brief, a paper was retracted from science because the raw data could not be presented. The computer containing the data has apparently been stolen and no backup existed. There are other similar stories on retractionwatch.com (https://retractionwatch.com/2016/02/23/we-are-living-in-hell-authors-retract-2nd-paper-due-to-missing-raw-data/, https://retractionwatch.com/2017/01/20/boom-headshot-disputed-video-game-paper-retracted/). It is not always clear if there were misconduct, but it seems the absence of data makes it impossible for researchers to prove they did not misconduct.
