Leading American Research Universities in the Sciences based on NAS Membership

The National Academy of Sciences is somewhat more selective than the American Academy of Arts & Sciences, though has some of the same "friends of friends" problems in its membership, but perhaps not as bad.  Many of the schools on this list do not have medical schools (e.g., Berkeley, MIT, Princeton, Cal Tech, among others), while some are essentially only medical schools (e.g., UT Southwestern and UC San Francisco).  In any case, for your amusement, here are the American universities with the most elected Fellows
