For nearly a decade, the Laboratory, in partnership with its
sister Defense Programs laboratories and the Department of Energy
(DOE)/National Nuclear Security Administration (NNSA), has maintained
the enduring nuclear stockpile without nuclear testing. National
science-based Stockpile Stewardship is the program through which
the safety, reliability, and performance of the United States
nuclear stockpile is assured. Through Stockpile Stewardship and
other programs, LANL develops and applies the best science and
technology to meet national security requirements by creating
and adapting capabilities to address critical mission needs.
A new study, led by Los Alamos National Laboratory, suggests that widespread loss of a major forest type, the pine-juniper woodlands of the Southwestern US, could be wiped out by the end of this century due to climate change, and that conifers throughout much of the Northern Hemisphere may be on a similar trajectory.
Scientists from Los Alamos National Laboratory, in collaboration with a group at the University of Illinois at Urbana-Champaign, the Lawrence Berkeley National Laboratory's Advanced Light Source and with other researchers nationwide, have realized a nanoscale, artificial magnet by arranging an array of magnetic nano-islands along a geometry that is not found in natural magnets. Their paper 'Emergent reduced dimensionality by vertex frustration in artificial spin ice' appears on the journal Nature Physics' website today.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
