Using data from NASA's Van Allen Probes, researchers have tested and improved a model to help forecast what's happening in the radiation environment of near-Earth space.
"The Van Allen Probes are gathering great measurements, but they can't tell you what is happening everywhere at the same time," said Geoff Reeves, a space scientist at Los Alamos National Laboratory. (Full Story)
Detecting bioterrorism: Is chemistry enough?

A biological attack could spread through a population quickly and have a devastating effect. An early detection system would be key to reducing a population's chance of exposure. The challenge is how to detect and identify an agent before people start getting sick.
"The 2001 anthrax letters contained only a few grams of material--about two sugar cubes' worth. So how do we protect ourselves against a whole bag of sugar?" said Kristin Omberg, a Los Alamos National Laboratory chemist. (Full Story)
Production of tetrapod quantum dots closer
Quantum Materials Corp. announced that the Los Alamos National Laboratory's Thick-Shell technology will be integrated with a variety of QMC's composite tetrapod quantum dots to develop a line of advanced high performance quantum dots.
QMC has teamed with LANL and jointly written and submitted a proposal for funding to the recent DOE EERE Funding Opportunity for Solid-State Lighting Advanced Technology R&D, which aims to increase performance and market readiness of efficient LED lights incorporating improved quantum dots.

An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer products ranging from cell phones to automobiles.
The device has been developed by a team of scientists from Vanderbilt, Alabama-Birmingham, and Los Alamos National Laboratory and is described in the journal Nano Letters. (Full Story)
Is ECC performance price worth it?
One of several elements that separates high performance computing GPUs from their gaming and graphics brethren is the addition of Error Correction Codes (ECC).
According to researchers from the San Diego Supercomputer Center and Los Alamos National Laboratory, enabling ECC cuts the size of the system available by 10% because of the amount of memory consumed by the error correction codes. (Full Story)
