Regarding the article on udder tampering in livestock competitions, it’s sad that the push for easy success is so pervasive. Although colleges and universities receiving federal research funds must require research-ethics education of their students, I don’t see an impact on plagiarism. How might we encourage future generations of students in all disciplines to internalize a more positive ethical code? Perhaps we need some brainstorming on this issue in scientific journals.
