After a half-century of searching, the neutron's electric dipole 
moment (EDM) remains elusive to experimentalists.  However, searches for 
non-zero values remain one of the best ways to look for physics beyond the 
standard model.  An international consortium has formed to carry out a new 
experiment, first in Los Alamos (LANSCE) and later at Oak Ridge (SNS), to 
search with roughly two orders-of-magnitude increase in sensitivity.  The 
improvement is driven by the properties of liquid helium, which allow 
higher production rates, longer storage times, and greater electric-field 
strengths.  The project is the middle of a vigorous development program 
that has already helped validate parts of the technique.
