Top 50 universities by membership in the National Academy of Sciences, 2018 (CORRECTED AGAIN)

The National Academy of Sciences is the even more selective "science only" cousin of the American Academy of Arts & Sciences.  While it does elect faculty in the social sciences, its focus is on the natural sciences and the biological sciences, including those in and around medicine; any university with a good medical school tends to do better, all else being equal, in NAS representation (indeed, some top medical schools, like UC San Francisco and Texas Southwestern in Dallas make the list, despite not being full service research universities).  As a result I mark with an asterik (*) universities without medical schools, and I mark with a # universities with medical schools with very high research profiles  (Some schools, like UT Austin and Illinois/Urbana have only recently added medical schools.)  As with the AAAS, there is a certain amount of "the rich get richer" at the NAS, though the schools with the most members are indeed very strong in the sciences.
