•ALICE is collecting data and producing papers. Computing and Upgrade?

• The first experimental campaign with the AGATA demonstrator has started at LNL. The realization of ¼ of solid angle is in progress. Nuclei at extremes are being investigated.

•Esperiments engaged in upgrades such as JLAB and LUNA are progressing.

• Several relevant results are obtained with the analysis of experiments under way. They are important to guide the future programs.

We count on the activity at JLAB We count on the activity at JLAB for which also in the future (as in the for which also in the future (as in the past) we expect outstanding results !past) we expect outstanding results !
