"Marilyn Fogel, a University of California, Riverside endowed geoecology professor, received one of the highest honors in science this week with her election to the National Academy of Sciences, or NAS.
Membership in the NAS is rare. According to the Congressional Research Service, there are 6.9 million scientists in the U.S. However, there are only 2,347 active NAS members and 487 foreign associates."
