Researchers at the National Institute of Standards and Technology (NIST) have reported* the first observation of the "spin Hall effect" in a Bose-Einstein condensate (BEC), a cloud of ultracold atoms acting as a single quantum object. As one consequence, they made the atoms, which spin like a child's top, skew to one side or the other, by an amount dependent on the spin direction. Besides offering new insight into the quantum mechanical world, they say the phenomenon is a step toward applications in "atomtronics"—the use of ultracold atoms as circuit components.
This artist’s conception shows atoms in a Bose-Einstein Condensate (BEC) being pushed by laser light. When the atoms, which all have the same magnetic spin orientation (represented by their blue and yellow "poles"), are pushed toward the viewer, they drift to the right because of their spin -- a result of the spin Hall effect, which has been observed in a BEC for the first time.

Helsinki, Finland - April 8, 2013 - Vaisala is celebrating the 30-year anniversary of the U.S. National Lightning Detection Network® (NLDN), the most accurate, reliable and scientifically validated lightning detection network in the United States. Since the first lightning location data was recorded on June 1, 1983 the NLDN has contributed 30 years of lightning data, improving meteorological forecasting of storm activity; protecting critical power, utility and communications infrastructure from lightning damage; and enabling issuing safety warnings and educating the public about the dangers of lightning.
