Years after the end of data taking, the Babar collaboration still provides world class measurements on flavor Physics. I will review two of the latest results on the violation of fundamental symmetries: the first direct evidence of T-symmetry violation in the evolution and decay of the B0 meson, and a search for CP violation in B0B̅0 oscillation with a new method, which involves kaon tag and partial reconstruction of the semileptonic decay B0 -> D*+ l- ν̅l.
