These issues of research fraud come up often, but the root of the problem is a bit more subtle. In North America at least, biomedical research labs operate largely as fiefdoms of the individual principal investigators (PIs). The actual research work falls almost entirely on the backs of grad students and postdoctoral fellows. The grad students need to generate "good" data in order to graduate, the postdocs need the s…
To add to the injury, you wouldn't believe the extent of the actions to which some PIs become engaged in order to attain/preserve their 'power'. Illegal, unethical and pathetic.
