The nuclear modification factor R{sub AA} has, for more than one decade, been one of the workhorse variables in the field of ultra-relativistic heavy-ion collisions. It describes the deviations of the yield of a given probe, such as {pi}{sup 0} yields, as compared to the yield that would have been obtained from a simple-minded superposition of independent proton-proton collisions. In addition to new {pi}{sup 0} suppression results in Au+Au collisions at {radical}s{sub NN} = 200 GeV, we present recent results from {pi}{sup 0} yields from the currently ongoing RHIC low energy scan, measurements of the jet fragmentation function in Cu+Cu and the R{sub AA} from fully reconstructed jets in Cu+Cu collisions.
