The objective of this paper is to apply the recent achievements in understanding of the non-MHD effects in plasma (acquired both in laboratory experiments, as well as in theory), to the interstellar phenomena. Applied to the space plasma, these effects can significantly change the picture of plasma dynamics. Charged dust particles are always present in the interstellar medium and can easily remain not magnetized, even when the plasma electrons and ions are strongly magnetized. In such a medium, the magnetic field can propagate with the super-Alfven velocity. This breaks the local "frozen-in" law for the magnetic field, which can significantly affect the gravitational collapse phenomena, the space plasma turbulence spectrum, magnetic dynamo and the rate of the Fermi acceleration of cosmic rays.
