Abstract
I shall describe the change of the star formation paradigm that is induced by the violation of flux freezing condition in turbulent fluids. The violation arises from the fast magnetic reconnection process in turbulent fluids that was described in Lazarian & Vishniac 1999 study and confirmed in the later numerical simulations. I shall discuss how the violation of magnetic flux freezing changes the evolution of gravitating subcritical clouds and magnetized accretion disks.
