  Four years of AMANDA-II data have been searched for neutrinos from point
sources. No statistically significant excess of events has been detected,
neither integrated in the years 2000 to 2003, nor in the searches for
occasional signals. An interesting coincidence of neutrinos with gamma-ray
flares emerges when inspecting the time of the events detected from the
direction of the Blazar 1ES1959+650. The exceptional character of the gamma-ray
observation provides a strong motivation for consolidating similar search
strategies with AMANDA and its successor IceCube, as well as for
multidisciplinary investigations of this and other gamma-ray sources. We report
the outcomes of the most recent survey of the northern sky to search for
neutrino point sources with AMANDA-II. We also discuss possible viable
collaborations between the gamma-ray and the high energy neutrino
observatories.
