The LUX collaboration new results advance the search for dark mattercandidate particles in the 4 GeV/c^2 and higher mass range, with a maximalspin-independent 90% C.L. limit of 2 x 10^-46 cm^2 at 50 GeV/c^2 for its 332live-day run, following after 6 x 10^-46 cm^2 cross-section for 33 GeV/c^2 massfrom the re-analysis of its initial 95 live-day WIMP search data from December2015. LUX has performed multiple advanced in situ neutron and beta/gammacalibrations of light and charge yields down to 1.1 and 0.7 keV, respectively,in nuclear recoil energy and 1.3 and 0.2 keV in units of electron recoilenergy, thereby bypassing the past practice of extrapolating yields from exsitu calibrations or simulation models alone. For this conference proceedings,consequences of the new calibrations for the limit on the interactioncross-sections for low-mass WIMPs will be highlighted. Previous claims of aWIMP signal, from other detectors, are now even more strongly disfavored,assuming isospin invariance and the standard WIMP halo model. Bothspin-independent and spin-dependent limits will be discussed, including therecent completion of LUX's 332-live-day blind run. Lastly, we highlight theconceptual design and future plan for its 10-ton-scale, next-generationsuccessor LZ, which plans on achieving < 3 x 10^-48 cm^2 sensitivity for a WIMPof mass 40 GeV/c^2.
