Large supercrystals promise superior sensors

ALBUQUERQUE, N.M. — Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve the detection sensitivity for chemicals in explosives or drugs. “Our supercrystals have more sensing capability than regular spectroscopy instruments currently in use, just like a […]

Arm-based supercomputer prototype to be deployed at Sandia National Laboratories by DOE

ALBUQUERQUE, N.M. — Microprocessors designed by Arm are ubiquitous in automobile electronics, cellphones and other embedded applications, but until recently they have not provided the performance necessary to make them practical for high-performance computing. Astra, one of the first supercomputers to use processors based on the Arm architecture in a large-scale high-performance computing platform, is […]

Exploring Arctic clues to secure future with new Sandia, university partnership

ALBUQUERQUE, N.M. — The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in the future, Sandia scientists say. […]

HADES creates alternate reality to mislead hackers

 ALBUQUERQUE, N.M. —The Russian novelist Fyodor Dostoevsky once postulated that the devil no longer uses fire and brimstone but instead simply tells you what you want to hear. Sandia National Laboratories cyber researchers go with that second option when it comes to foiling a hacker. Rather than simply blocking a discovered intruder, Vince Urias, Will […]

Sandia’s international peer mentorship program improves biorisk management

ALBUQUERQUE, N.M. — The world is becoming increasingly interconnected. While this has definite advantages, it also makes it easier to spread disease. Many diseases don’t produce symptoms for days or weeks, far longer than international flight times. For example, Ebola has an incubation period of two to 21 days. Improving biosafety practices around the world […]

Cleaning up subways: Sandia’s 20-year mission to stop anthrax in its tracks

ALBUQUERQUE, N.M. — If you’re like most people, you don’t spend much time thinking about what would happen if anthrax was released into your local subway system. Luckily, Sandia National Laboratories engineer Mark Tucker has spent much of the past 20 years thinking about incidents involving chemical or biological warfare agents, and the best ways […]

Scintillating discovery at Sandia Labs

Bright thinking leads to breakthrough in nuclear threat detection science LIVERMORE, Calif. — Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators — objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials […]

Overcoming the trust barrier in nuclear weapons verification measurements

Sandia method supports real-time warhead verification without revealing design data LIVERMORE, Calif. — Trust but verify. The catchphrase for arms control popularized by President Ronald Reagan sounds simple. However, verification involving sensitive data is a very complex endeavor. Verifying that a nuclear warhead actually is a warhead may include confirming key attributes. But the act […]

Sandia adds augmented reality to training toolbox

ALBUQUERQUE, N.M. — When you hear the term “serious gaming” you might envision professional eSports competitors gearing up for a League of Legends World Championship in front of tens of thousands of live fans and tens of millions of streaming fans. At Sandia National Laboratories, serious gaming means something else entirely. Experts on physical security […]

Designing diagnostic labs that are safe, specific and sustainable

Sandia develops new method of designing high-quality public health labs faster ALBUQUERQUE, N.M. — An outbreak is like a wildfire; the sooner it’s caught, the easier it is to fight, said Vips Halkjaer-Knudsen, a lab design expert at Sandia National Laboratories. To detect an outbreak early — whether Ebola, Zika or influenza — healthcare workers […]
