We present new results from ongoing lattice investigations of supersymmetric Yang--Mills (SYM) theories in three and four space-time dimensions. First considering the maximally supersymmetric 3d theory with Q = 16 supercharges, we check that the fermion pfaffian is approximately real and positive, validating phase-quenched RHMC calculations. We then initiate lattice studies of running couplings and non-perturbative β functions for Q = 16 SYM in both 3d and 4d, using a simple scheme based on Creutz ratios. Finally, we consider 3d SYM with Q = 8 supercharges, developing new software as a first step towards supersymmetric QCD.
