When discussing open science I was pointed to mathematician Grigori Perelman (he was awarded Fields Medal), who published his findings in arXiv _only_. A paper based on his work appeared in peer-reviewed journal, but was retracted due to plagiarism charges.

My feeling is, that also in life sciences community would react to majority of cheating attempts, if they would have have tools and some procedures to follow. What I mean by that, is the wide usage of preprint servers (I mean really wide), and some way to flag publication in a peer-reviewed journal as a subject for retraction (this is very important, convincing editor to retract publication from high-profile journal is almost impossible if the paper has false results, and really impossible if results are stolen). Actually I'm quite surprised that we are still pointing to the same example of blogger getting authorship over and over again. Don't we have any more encouraging stories?
