  The dusty plasma liquid formed by micro-meter sized particles negatively
charged and suspended in a low pressure discharge background is a good
candidate to study the generic spatio-temporal dynamical behaviors at the
kinetic level through direct optical video-microscopy, because of the sub-mm
interparticle spacing and the slow time scale. In this paper, starting from the
basic picture of the avalanche type stick-slip cooperative hopping process
under the interplay of mutual coupling and the stochastic thermal agitation, we
briefly review our recent study on particle micro-motion and the associated
structural rearrangement. The effect of mesoscopic confinement and external
slow shear drive are also discussed.
