Re-routing exascale simulation storage, power concerns

Podcast: Today we’ll be talking about power and storage constraints for exascale-class simulations with Jim Ahrens, Visualization Team Leader at Los Alamos National Laboratory.

We’ll discuss these problems in the context of what Ahrens calls “cost per insight” and touch on some of the novel ways to make sure that cost is kept as low as possible using in situ analysis and storage, as well as other approaches. (Full Story)

Infrasonic detection of meteorites

November 17, 1998, a bright fireball was observed over northern New Mexico, Los Alamos National Laboratory (LANL) investigated the sighting in its role as a part of the International Monitoring System (IMS).

LANL found the presence of an infrasonic signal detected by six infrasound arrays. The signal matched the time and the direction of the fireball seen in the sky. The infrasound recording indicated that the explosion occurred at 93.5 kilometer, matching the measurements from the camera. (Full Story)

Quantum dots make see-through solar cells a reality

Researchers at Los Alamos National Laboratory have developed a way to magnify the amount of light that gets sent to solar cells using quantum dots to build luminescent solar concentrators.

The researchers embedded quantum dots in a transparent sheet of polymethylmethacrylate. Quantum dots are nanoscale bits of semiconducting material manufactured with atomic precision using colloidal chemistry. (Full Story)

Study validates air sampling techniques to fight bioterrorism

Results published in Biosecurity and Bioterrorism by Alexander Garza, M.D., and a team of researchers from Los Alamos National Lab reviewed the data from a series of experiments simulating a bioterrorism attack.

Garza is now the associate dean for public health practice and associate professor of epidemiology at Saint Louis University College for Public Health and Social Justice. (Full Story)

Members of Girl Scout Troop 116 are Rocketeers! The scouts, comprised of Los Alamos sixth grade students and one home school, are advised by Ryn Herrmann and Nan Holmes.          

The 206 rockets celebrate the number of rockets launched into space that carried instruments built by Los Alamos National Laboratory. RocketFest is a partnership of Troop 116, the National Association of Rocketry, Zia Spacemodelers, the Kiwanis Club and Los Alamos County. (Full Story)
