Abstract: Matrix models of Yang-Mills type describe noncommutative spaces, which are considered as models for dynamical space-time. Gravity arises on these branes through an intrinsically noncommutative mechanism. We review recent progress in the understanding of this emergent gravity. The metric is not fundamental but arises effectively in the semi-classical limit, along with nonabelian gauge fields. This leads to a mechanism for protecting certain geometries from quantum corrections, including flat space-time
