We are participating in the experiments GEM at the SSC and MACRO at the Gran Sasso. After introducing GEM in chapter II, we present some results from GEM work we have done during the current contract period. Other significant GEM activities by our group such as participation in the evolution of GEM (as founding fathers), GEM proposal writing, and the design of GEM electronics for the Interpolating Pad Chambers for the Central Tracker are not included in this report.In chapter III we introduce MACRO and give a brief status report. Instead of a survey of our many ongoing contributions to MACRO, we choose in this technical report to concentrate on reporting results of some MACRO data analysis headed by our group (with important contributions by our collaborators, of course). This analysis, in chapter IV, concerns Point Sources.
