Satsunet is a list for sharing information and developing links across three key areas - the sociology of the biosciences, science policy and regulation, and social media/informatics. The list is managed by the Science & Technology Studies Unit at the University of York, which has a particular interest in the relationship between the social construction of policy and the social construction of innovation, with an emphasis on issues of practical importance, on subjects that are of relevance to policy debates and on questions of power and social exclusion.
