The heavy ion collision provides a unique many-body environment where local domains of strongly interacting chiral medium may occur. Certain anomalous transport processes, forbidden in usual medium, become possible in such domains. These anomalous chiral effects have their microscopic origin at the fundamental quantum anomaly and manifest themselves macroscopically in hydrodynamic currents. In the first part of this talk we report our recent finding (arXiv:1504.03201) of a new gapless collective excitation, called the Chiral Vortical Wave (CVW) in a rotating quark-gluon plasma. The CVW wave equation will be derived, and we show that its solutions describe nontrivial CVW-induced charge transport. We further propose and estimate possible experimental signals. In the second part of this talk we report our state-of-the-art simulations of the long-sought-after Chiral Magnetic Effect (CME), performed in the anomalous hydrodynamic framework and taking into account identified background contributions (arXiV:1504.06906). We discuss the implications of our results for the experimental search of CME
