Computer simulations predict the spread of HIV

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

In a recently published study in the journal Nature Microbiology, researchers at Los Alamos National Laboratory show that computer simulations can accurately predict the transmission of HIV across populations, which could aid in preventing the disease.

Large supercrystals promise superior sensors

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Supercrystals grown from tiny particles of gold have finer sensing capabilities than those commonly used to detect the chemicals in drugs or explosives.

Dry casks take the heat

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories researchers have built a scaled test assembly that mimics a dry cask storage container for spent nuclear fuel to study how fuel temperatures change during storage and how the fuel's peak temperatures affect the integrity of the metal cladding surrounding the spent fuel. Regulators could use the data to help verify computer simulations that show whether nuclear power utilities are complying with regulations that specify how much heat a dry cask can safely handle.

Feeding plants to this algae could fuel your car

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

The research shows that a freshwater production strain of microalgae, Auxenochlorella protothecoides, is capable of directly degrading and utilizing non-food plant substrates, such as switchgrass, for improved cell growth and lipid productivity, useful for boosting the algae's potential value as a biofuel.

Generating electrical power from waste heat

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Researchers from Sandia National Laboratories have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. Their advance was recently published in Physical Review Applied.

Smarter, safer bridges with Sandia sensors

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories has worked for over 15 years to turn science-fiction smart bridges that can send out warnings when they're damaged into science fact.

Diesel doesn't float this boat

DOE/Sandia National Laboratories
Business Announcement

Marine research could soon be possible without the risk of polluting either the air or the ocean. It's thanks to a new ship design and feasibility study led by Sandia National Laboratories.

Sandia light mixer generates 11 colors simultaneously

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A multicolor laser pointer you can use to change the color of the laser with a button click -- similar to a multicolor ballpoint pen -- is one step closer to reality thanks to a new tiny synthetic material made at Sandia National Laboratories. Research on the new light-mixing metamaterial was published in Nature Communications earlier today.

Solar tower exposes materials to intense heat to test thermal response

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories is using its solar tower to help assess the impact of extreme temperature changes on materials. The tests, now in their second year, take advantage of the ability of Sandia's National Solar Thermal Test Facility to simulate a very rapid increase in temperature followed by an equally rapid decrease. The testing is for the Air Force and will continue for at least another year.

Study confirms beetles exploit warm winters to expand range

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new study by Los Alamos National Laboratory scientists and colleagues confirms that increasing minimum winter temperatures allow beetles to expand their range but reveals that overcrowding can put the brakes on population growth.
