Ive spent 6 months doing western blots trying to workout whether the protein i was interested in was actually not expressed or whether something was wrong. It turned out that the commercial antibodies I was using had failed.
Theres enough pressure in research to destroy ones confidencce and self esteem and I genuinly understand that urge to sometimes just turn a blind eye or pretend I saw something I didnt.
At the end of the day though you have to be honest with yourself and decide which road you will travel. Im glad they didn't strip him of his PhD. The public humiliation will warrant enough misfortune for the scientist and hopefully he will learn from his mistakes.
