After nearly 2 years I think PLOS has come really far. We link to their papers often, and some of their reviews by freelance journalists have been really informative. In any case, just so you know next month PLOS Genetics premiers. They have a preview of an interview with Dr. Neil Risch up. Risch is notable for two reasons, 1) he defends the idea of race as a genetically coherent concept (this is alluded to in the preview) and 2) he has put forward the standard model that diseases like Tay Sachs are the result of genetic drift cranked up due to extreme founder effect within Jewish populations.
