Masatoshi Koshiba, professor of physics at the University of Tokyo, Japan, and Raymond Davis, professor of physics at the University of Pennsylvania, USA, have been awarded the prestigious Wolf Prize for physics for their investigations of the elusive subatomic particles, neutrinos. The prize citation noted that their findings and observations "have opened a new window of opportunity for the study of astronomical objects, such as the Sun and exploding stars, and the fundamental properties of matter." Koshiba visited the ICTP in July 1998, just a few weeks after the discovery of neutrino's mass in Japan's SuperKamiokande detectors. Koshiba led the detectors' design and construction team. Both he and Davis will receive $100,000. The awards ceremony will take place at the Israeli Knesset (Parliament) on 21 May.
