Pioneering research involving the detection of cosmic neutrinos and X-ray radiation has won three scientists the Nobel Prize in Physics.
Raymond Davis of the University of Pennsylvania, US, and Masatoshi Koshiba of the University of Tokyo, Japan, have been jointly awarded half the US$1 million prize for fundamental groundwork in the detection of cosmic neutrinos.
Riccardo Giacconi of Associated Universities in Washington, US, has received the other half for constructing space-based cosmic X-ray detectors.
