LUX (Large Underground Xenon) is a dark matter direct detection experiment deployed at the 4850' level of the Sanford Underground Research Facility (SURF) in Lead, SD, operating a 370 kg dual-phase xenon TPC. We have recently reported the results of the first WIMP search dataset, taken during the period of April to August 2013, presenting the analysis of 85.3 live-days with a fiducial volume of 118 kg. The experiment exhibited a sensitivity to spin-independent WIMP-nucleon elastic scattering with a minimum upper limit on the cross section of 7.6 x 10^-46 cm^2 at a WIMP mass of 33 GeV/c^2, establishing the best limits in the literature. This sensitivity is inconsistent with the low-mass WIMP signal interpretations of the results from several recent direct detection experiments. This talk will provide an overview of the experiment, focusing in the recent science results.
