In the 19th May issue of Nature there is:
An editorial on "policing integrity"
A special report. The report looks at the use of technology to spot plagiarism, the sort of technology that is now used to spot plagiarism in students' assignments.
In the latest issue (7th July) there are three letters responding to this. One argues that it is the nature of science to publish or present findings in stages, then to consolidate them. Another reports that a journal paper they had written appeared after a summary of that paper in a book, because of publication delays.
