Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

Magnetic particles with high permeabilities and moments, and low losses, have considerable potential for high-frequency power applications. In this paper, we report on spherical Co/sub 50/Fe/sub 50/ ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.
