✦ Synopsis

We briefly summarize some recent work on nucleosynthesis in massive stars and supernovae. Here we explore: 1) the effect of including additional sources of nucleosynthesis besides massive stars into the mixture -especially classical novae and several varieties of Type Ia supernovae; 2) the sensitivity of the results to choices of theoretical nuclear reaction rates in the mass range 28 _< A < 70; 3) nucleosynthesis above the iron group using a much larger reaction network; and 4) the sensitivity of these results to recent revisions in experimental reaction rates for isotopes A < 28. For the recently revised rates, 170 is no longer a massive star product.
