Dramatic changes had occurred with our understanding of quark-gluon plasma, which is now believed to be rather strongly coupled. One set of questions is what is its internal structure: at the moment the best answer seem to be a liquid made of binary bound states. Another set of questions is how to probe it, especially using hard probes of the main interest to this meeting. Three suggestions to be discussed are (i) the ionization losses related to new bound states; (ii) the “conical flow” from quenched jets; (iii) possible new peaks in the dilepton spectra, corresponding to vector mesons above T c .
