UC Davis/- The recent crash of NASA's Genesis space probe may have looked like bad news for scientists, but its cargo of particles captured from the sun should still yield useful information, according to Qing-Zhu Yin, a planetary scientist at UC Davis.     Yin, who is not directly affiliated with the Genesis mission, studies the composition of meteorites to learn about the formation of the solar system...
