  Several new effects have been investigated in recent analyses of
supersymmetric dark matter. These include the effects of the uncertainties of
wimp velocity distributions, of the uncertainties of quark densities, of large
CP violating phases, of nonuniversalities of the soft SUSY breaking parameters
at the unification scale and of coannihilation on supersymmetric dark matter.
We review here some of these with emphasis on the effects of nonuniversalities
of the gaugino masses at the unification scale on the neutralino-proton
cross-section from scalar interactions. The review encompasses several models
where gaugino mass nonuniversalities occur including SUGRA models and D brane
models. One finds that gaugino mass nonuniversalities can increase the scalar
cross-sections by as much as a factor of 10 and also significantly extend the
allowed range of the neutralino mass consistent with constraints up to about
500 GeV. These results have important implications for the search for
supersymmetric dark matter.
