Predicting with uncanny accuracy the effects of recent hurricanes, Los Alamos National Laboratory computer models are helping the Department of Energy’s Office of Energy Assurance, the Federal Emergency Management Agency (FEMA) and other organizations plan for future disasters. For those in the paths of hurricane devastation, tools such as the Los Alamos infrastructure models could mean their lights and gas return to service hours or even days more rapidly.
"The comparison of actual effects to those predicted by the computer models was amazingly close, considering the variable storm tracks," said Steve Fernandez, leader of the Los Alamos Energy & Infrastructure Analysis team. Working to model electric power restoration across storm-damaged areas, the scientists have been able to provide detailed information to planners on the exact infrastructure impacts, a feat even more remarkable in that the models were run before the hurricanes made landfall.
The computer models were put to the test under fire as Hurricane Jeanne approached the Florida coast in September. Multi-agency teams assembled in the state emergency operations center in Tallahassee and the national emergency operations center in Washington. These command centers coordinated the evacuation and recovery activities as the hurricane approached and then moved through Florida and other southern regions. The models supplied updated predictions to the two centers and to the decision makers responding to the approaching storm.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
