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?

Graphene Nanoribbons
A new path to spintronics
Spintronics — the principle behind electronic devices based on the spin of an electron, in addition to its charge — is the gleam in the collective eyes of the computer industry. With the discovery of a new pathway towards realizing the spintronics dream, that gleam should light up even brighter.
Theorists from Berkeley Lab’s Materials Sciences Division and the University of California at Berkeley have calculated that nanoribbons of graphene — single-layered sheets of hexagonally arranged carbon atoms — with zigzag edges can be made to carry a spin current. Zigzag graphene nanoribbons could therefore serve as the basis for nanosized spintronic devices.
