Denmark has been rocked by a science fraud case involving a high-profile professor of medicine specialising in brain research. The case has also embroiled the rector of Copenhagen University, the previous minister of science and a number of co-authors, and has undermined the public view of science.

A recently published survey study of PhD students in Denmark reveals that an ethically questionable culture for assigning authorships to research papers is widespread within the medical and natural sciences across Europe. 49% of the PhD students in medical sciences had granted guest authorship to a person in power while 42% were in the natural and technical sciences.
