Objective "The nature of interactions between different scales in magnetohydrodynamic (MHD) turbulence is paramount for the understanding of flows occurring in fusion plasmas, the geospace, the heliosphere, the interstellar medium, and their influence for example on cosmic ray propagation, the solar-terrestrial interactions. The different degrees of nonuniversality observed at present studies, and the existence of nonlocal processes in MHD turbulent flows, call for a discussion about the validity of the locality hypothesis of scale interactions and the universality in MHD turbulence. We try to gain insight into this problem by performing high fidelity computations of MHD turbulence for massive parallel computers. We focus on the origins of nonuniversal statistics that are hidden in the complex dynamics of MHD turbulence, such as turbulent cascades, scale interactions, energy transfer and dissipation. We examine the long-range interactions, which are associated with departures from universality and can lead to the persistence of small-scale anisotropies and the development of intermittency."
