  • The computing issue
    Los Alamos National Laboratory has led the world in developing and using computer simulations to understand the world around us.


  • Listen up
    National Security Science now has a podcast!
  • Ask a physicist
    Three questions for Charlie Nakhleh, the new Associate Laboratory Director for Weapons Physics.
  • The power of social media
    By analyzing social media, governments can “poll” remote areas to better gauge policy decisions.
  • Automating at exascale
    A new parallel programming system boosts supercomputing performance and efficiency.
  • Not your average trash day
    The Laboratory’s current weapons work results in transuranic waste, which is carefully shipped offsite.
  • Must-read books about Lab history
    Five favorites from members of the Lab’s National Security Research Center.
  • Squashing superbugs
    Some bacteria are resistant to disinfectants— but not for much longer.
  • Working smarter
    Expanding the computer codes that are used to simulate how nuclear weapons work will help scientists think about how to update weapons.
  • Detecting deepfakes
    Scientists use machine learning to expose deceptive, sometimes dangerous, videos.
  • A blast from the past
    A 1940s-era explosives site is now a protected archaeological site.


  • Computing on the mesa
    Scientists’ need to process, store, and visualize large quantities of numerical data to simulate physical phenomena has kept Los Alamos on the front lines of computing.
  • Cool computing
    Warm water mixed with a little detergent keeps supercomputers f rom overheating.
  • The bizarre and promising world of quantum computing
    Quantum computers derive their (potentially) extreme speeds from the mysterious properties of quantum physics.
  • “We thank Miss Mary Tsingou”
    A half-century after being mentioned in the footnote of a seminal physics paper, one of the Laboratory’s first computer programmers gets the recognition she deserves.
  • Computing for a cure
    COVID-19 poses an unprecedented threat to national security. But scientists at Los Alamos National Laboratory are fighting back by harnessing the power of computers.
