An all-day symposium on “New Directions i n Neutron Scattering Instrumentation for Protein and Membrane Crystallography” was held at the annual meeting of the ACA in Arlington, Virginia on July 23, 1998. The aims of the organizers, Benno Schoenborn and Bob von Dreele (LANL), were to promote and to make provisions for new technical developments which promise to broaden the application of neutron diffraction in structural biology. Ten speakers presented recent accomplishments in the application of neutrons to biology using a variety of different diffraction techniques to an audience of about 50.
