Several faculty members (Profs. Rhodes, Gligorov, Holzman, Philpott and Schwab) recently published a paper proposing a new category of risk for human subjects research. Their paper, based on work from a large NIH-funded project entitled 'The Human Microbiome and the Social Fabric' and in response to the Department of Health and Human Services recently advance notice of proposed rulemaking for human subjects research, appears as an editorial in the November 2011 issue of The American Journal of Bioethics. http://bioethics.net/journal/
