The National Academy of Sciences (NAS) awards announcement. The awards will be presented on April 19 at a ceremony in Washington, D.C., during the Academy's 141st annual meeting.

Comstock Prize in Physics – a prize of $20,000 awarded approximately every five years to a resident of North America for recent innovative discovery or investigation in electricity, magnetism, or radiant energy, broadly interpreted – goes to John N. Bahcall, Richard Black Professor of Natural Science, Institute for Advanced Study, Princeton, N.J. Bahcall was chosen "for his many contributions to astrophysics, especially his definitive work on solar models and his crucial role in identifying and resolving the solar neutrino problem." The prize was established through the Cyrus B. Comstock Fund and has been presented since 1913.
