Physics Today: Statisticians at the NSF have just published their analysis of enrollments in 2008 of first-time, full-time graduate students in science and engineering. The numbers show a record total, 108 819, which results from a 7.8% increase from the previous year. For the first time since 2003, first-time enrollment in engineering fields grew faster among US citizens and green-card holders than among foreign students with temporary visas. That trend was not repeated in the physical sciences, however. First-time US enrollment in those fields fell 2.5% from 2007 to 2008; non-US enrollment rose 10.8%.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
