Experiment improves predictions of uranium dispersion

The predictive models that describe the fate and transport of radioactive materials in the atmosphere following a nuclear incident (explosion or reactor accident) assume that uranium-bearing particulates would attain chemical ...

Planetary defenders validate asteroid deflection code

Planetary defense researchers at Lawrence Livermore National Laboratory (LLNL) continue to validate their ability to accurately simulate how they might deflect an Earth-bound asteroid in a study that will be published in ...

Lab confirms new commercial method for producing medical isotope

The effort to secure a stable, domestic source of a critical medical isotope reached an important milestone this month as the U.S. Department of Energy's (DOE) Argonne National Laboratory demonstrated the production, separation ...

Nuclear weapon simulations show performance in molecular detail

U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation ...

Crystals detect threats to national security

Using a crystal ball to protect homeland security might seem far-fetched, but researchers at Wake Forest University and Fisk University have partnered to develop crystals that can be used to detect nuclear threats, radioactive ...

Hawaiʻi phones capture data in Tonga volcano blast

The explosion of the underwater volcano Hunga Tonga-Hunga-Haʻapai on January 15, released a blast "sound" wave that reverberated through Earth's atmosphere and was recorded around the world by monitoring stations—and smartphones. ...
