A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation of magnetic fields using what may be the tiniest compasses around—atoms.

The California ballot is filled with initiatives this November, many of which have a direct bearing on health, transportation, water and other issues affecting our daily lives. One measure I hope you ...
