New initiatives at NSF focus on merging computer science and biology—a "Mathematical Biology Training Grant," a KDI initiative on biological/engineering problems and a recent research thrust on a complex biological system: flight control and dynamics in insects.  The Wellspring of Discovery This 50th anniversary symposium provides an opportunity to reflect on the agency’s role as a wellspring for discoveries. NSF's work has nourished discovery as well as our nation's economy; the challenge now is to sustain the exploration and to convey the "awed wonder" of science.
