Abstract
Several recent results of quasilinear cosmic ray transport theory are reviewed. It is shown that modelling the plasma turbulence beyond the magnetostatic approximation is most important for a correct description of cosmic ray dynamics. In particular, the effects of finite plasma wave speeds play a crucial role both for the behaviour of the particles' spatial diffusion coefficient and the diffusive acceleration by super-Alfvenic shock waves.
