Brain Drain: Can the U.S. survive as a scientific superpower even though hostility to science is endemic and the current administration is dedicated to stamping out any way of understanding the world that doesn’t have its roots in divine revelation? So far it’s done a pretty good job, largely because of its ability to import scientific talent.

The number of foreign science and engineering students staying to work in the U.S. peaked in 1996 and has been declining ever since.”
