The only recent news w.r.t. dark matter that I know of was the
conclusion that there was a lot more dark matter than previously
thought in a small (3 galaxy) cluster.  If the cluster is typical, the
universe is definitely closed.  The evidence for the dark matter is
still indirect; in this case it is necessary to confine the hot gas in
the cluster.

There are active direct searches for two different promising
candidates.  Subatomic Weakly Interacting Massive Particles (WIMPs)
are being searched for in accelerator results and in direct-detection
experiments (trying to see the heat they deposit when they interact
with very cold germanium).  Star-sized MACHOs (MAssive Compact Halo
Objects) are being probed by looking for lensing of stars in the
Mageleanic Clouds.  Both searches should have significant results in
a few years -- either they will find something, or the possibility of
that kind of dark matter will be somewhat constrained.  My favorite
candidate, massive neutrinos, wouldn't show up in these searches.
