Macchiarini scandal: overstepping the research ethics mark

The recent Macchiarini scandal has led to one of the most shocking case of scientific misconduct in recent years. It reveals a lot about the vanity culture pervading some fields of research. Our outlook on what constitutes success in research may need to be revised.
