A whole section of JMBE - the Journal of Microbiology and Biology Education dedicated to Scientific Ethics. Sounded intriguing. So I looked it up. Took a bit to find it but there it was from December 2014 - Volume 15 number 2
I don't know about the specific articles but the whole collection seems definitely worth a look and of potentially many uses.
So I have listed the individual papers below. Kudos to ASM and JMBE for putting this together. Now off to read some of the papers.
