Research from Sandia shows brain stimulation during training boosts performance

DOE/Sandia National Laboratories
Peer-Reviewed Publication

New research from Sandia published in Neuropsychologia shows that working memory training combined with a kind of noninvasive brain stimulation can lead to cognitive improvement under certain conditions. Improving working memory or cognitive strategies could be very valuable for training people faster and more efficiently.

Sandia honored for fighting Ebola, analyzing emerging biotechnologies

DOE/Sandia National Laboratories
Grant and Award Announcement

Researchers at Sandia National Laboratories just received recognition from the Secretary of Energy for their work to mitigate the effects of the 2014 Ebola epidemic.

Better living through pressure: Functional nanomaterials made easy

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Using pressure instead of chemicals, nanoparticles have been fabricated into nanowire arrays similar to those that underlie touch-screens for phones, computers, TVs, and sensors. The pressure process takes nanoseconds instead of the hours required by industry's current chemical means.

Drop of mock B61-12 is first of new flight tests

DOE/Sandia National Laboratories
Business Announcement

The drop of a mock nuclear weapon on Tonopah Test Range in Nevada marked the start of a new series of test flights vital to the nation's B61-12 weapon refurbishment program.

On-the-range detection technology could corral bovine TB

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A research breakthrough allowing the first direct, empirical, blood-based, cow-side test for diagnosing bovine tuberculosis (TB) could spare ranchers and the agriculture industry from costly quarantines and the mass slaughter of animals infected with this easily spread disease.

Predicting the limits of friction: Sandia looks at properties of material

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories materials scientists have developed a model to predict the limits of friction behavior of metals based on materials properties -- how hard you can push on materials or how much current you can put through them before they stop working properly.

Ultrafast measurements explain quantum dot voltage drop

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes.

Breaking the supermassive black hole speed limit

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new computer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials.

New brain-inspired cybersecurity system detects 'bad apples' 100 times faster

DOE/Sandia National Laboratories
Business Announcement

The Neuromorphic Cyber Microscope can look for the complex patterns that indicate specific 'bad apples,' all while using less electricity than a standard 60-watt light bulb, due to its brain-inspired design.

Less radiation in inner Van Allen belt than previously believed

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.
