An overview is given on two advances in the understanding and control of magnetic fluctuations and energy transport. First, it is reported that the previously achieved m=1 fluctuation reduction and confinement improvement are limited by bursts of edge-resonant m=0 magnetic fluctuations observed in conjunction with the auxiliary current drive. Second, it is shown that by suppressing the bursts, an additional improvement in energy confinement is achieved.
