A NERSC INCITE projectBridging the Gap between Climate and Weather
The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?

The Fusion Two-Step
Simulations elucidate the physics of fast ignition
To a dance aficionado, the term two-step may refer to the ballroom dance that evolved into the foxtrot, or to country/western dances like the Texas two-step and the Cajun two-step. But in the realm of alternative energy sources, one of the hottest new trends is the two-step fast ignition concept for inertial confinement fusion (ICF).
ICF is the process of initiating a nuclear fusion reaction by heating and compressing a fuel target, usually a pellet of deuterium-tritium (DT) ice. If a 10 milligram DT fuel pellet was completely consumed by fusion, it would release energy equivalent to more than half a barrel of oil.
