Is "Dark Matter" actually "Mirror Matter" (having inverse parity to "normal" matter)?

From PhysOrg.com:

The inspiration for mirror matter came from an experiment performed in 1956 that showed that the laws of nature are not left-right symmetrical (also called parity-symmetrical, or p-symmetrical). Specifically, the experiment showed that particles in weak interactions display a preference for left-handedness, so that in a way, the Universe is left-handed. Since the other two forms of symmetry - rotational and translational - do seem to be symmetrical everywhere in nature, scientists wonder why nature doesn’t have p-symmetry as well. But if mirror matter exists, it would solve this problem by having slight right-handedness and restoring the Universe’s p-symmetry.
