Two Japanese scientists and an American researcher have won the 2008 Nobel Prize [Images] for Physics for their discoveries in subatomic physics, the Royal Swedish Academy of Sciences announced on Tuesday.
    
American Yoichiro Nambu of the University of Chicago won half of the prize for the discovery of spontaneous broken symmetry in subatomic physics.

Makoto Kobayashi and Toshihide Maskawa of Japan [Images] shared the other half of the prize for discovering the origin of the broken symmetry that predicts the existence of at least three families of quarks in nature.
