DESCRIPTION:The Large Underground Xenon experiment is searching for intera
 ctions of galactic dark matter particles in a 250 kg liquid xenon target. 
 LUX features a double-phase xenon Time Projection Chamber at its core\, an
 d operates in a low background environment at the 4850-ft level of the San
 ford Underground Research Facility\, South Dakota\, USA. Results from its 
 first science run completed in 2013 put new constraints on the elastic sca
 ttering of Weakly Interacting Massive Particles (WIMPs) off nucleons. Very
  low energy threshold for nuclear recoil detection and novel calibration t
 echniques have allowed a 20-fold improvement in sensitivity for low mass W
 IMPs relative to the previous leading experiment\, changing the landscape 
 of direct searches for light WIMPs. The null result from LUX can only be r
 econciled with controversial signal claims by other experiments under the 
 most contrived set of astrophysical\, particle physics and experimental as
 sumptions. I will describe the experiment and this significant result\, an
 d discuss future prospects as LUX enters a longer science run in 2014.
