LABORATORY NEWS

  • Los Alamos National Laboratory noted successes ranging from high-performance computing (Trinity supercomputer, above, installed) to cancer research, space science, nuclear nonproliferation and more.

    Top Los Alamos science stories of 2016

    From discoveries on Mars to breakthroughs in cancer research, from national security science to materials science, 2016 has proven to be another productive year for Los Alamos National Laboratory achievements. 12/21/16

  • On the Greenland Ice Sheet, the ice flow more than doubles in speed in many regions during summer, as surface melt drains to the bed and lubricates the motion. This acceleration sends ice to the sea faster. However, the motion also slows down in late summer, fall, and winter, which largely offsets the summer speedup. New modeling data shows that a complex drainage system beneath the ice holds the giant sheet back more than previously understood.

    Leaky plumbing impedes Greenland Ice Sheet flow

    A team led by ice sheet modelers is exploring how changes in extensive, sediment-choked subglacial “swamps” actually explain why the ice sheet’s movement slows down in late summer and winter. 12/19/16

  • Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in the cytosol or within a membrane-bound vacuole.

    DNA markers distinguish between harmless, deadly bacteria

    The virulent pathogen that causes the disease tularemia, or “rabbit fever,” was weaponized during past world wars and is considered a potential bioweapon. 12/19/16

  • ChemCam target Catabola is a raised resistant calcium sulfate vein with the highest abundance of boron observed so far. The red outline shows the location of the ChemCam target remote micro images (inset). The remote micro images show the location of each individual ChemCam laser point (red crosshairs) and the B chemistry associated with each point (colored bars). The scale bar is 9.2 mm or about 0.36 inches. (Image Credit: JPL-Caltech/MSSS/LANL/CNES-IRAP/William Rapin)

    First detection of boron on the surface of Mars

    The boron was identified by the rover’s laser-shooting Chemistry and Camera (ChemCam) instrument, which was developed at Los Alamos National Laboratory in conjunction with the French space agency.12/13/16
