Modeling terrorist behavior with Sandia social-cultural assessments

DOE/Sandia National Laboratories

A team of Sandia social-behavioral scientists and computational modelers recently completed a two-year effort, dubbed 'Mustang,' to assess interactions and behaviors of two extremist groups. The purpose was to inform US and UK decision-makers about the groups' possible reactions to specific communications. The model suggested several communication options that are most likely to reduce the recruitment and violence of the extremist groups over time.

Engineered light to improve health, food, suggests Sandia researcher in Nature

Peer-Reviewed Publication

intentionally controlled light can help regulate human health and productivity by eliciting various hormonal responses. Tailored LED wavelengths and intensities also can efficiently stimulate plant growth, alter their shapes and increase their nutritional value, opening a new world of scientific and technological possibilities for indoor farming.

'Realistic' new model points the way to more efficient and profitable fracking

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new computational model could potentially boost efficiencies and profits in natural gas production by better predicting previously hidden fracture mechanics. It also accurately accounts for the known amounts of gas released during the process.

Heat it and read it

DOE/Sandia National Laboratories

Unlike most medical diagnostic devices which can perform only one type of test -- either protein or nucleic acid tests -- Sandia's SpinDx can now perform both. This allows it to identify nearly any cause of illness, including viruses, bacteria, toxins or immune system markers of chemical agent exposure.

More stable light comes from intentionally 'squashed' quantum dots

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Intentionally 'squashing' colloidal quantum dots during chemical synthesis creates dots capable of stable, 'blink-free' light emission that is fully comparable with the light produced by dots made with more complex processes.

Quantum computing steps further ahead with new projects at Sandia

DOE/Sandia National Laboratories
Grant and Award Announcement

Sandia Labs is constructing a small quantum computer available to government, industry and academia to test the system with their own algorithms. Other parts of the $42 million grants enable monitoring of the machine, making connections to ordinary programming language, and connections with high-level science problems.

Sandia microneedles technique may mean quicker diagnoses of major illnesses

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Microneedles able to draw relatively large amounts of interstitial fluid -- a liquid that lurks just under the skin -- opens new possibilities. Previously, microneedles -- tiny, hollow, stainless steel needles -- have drained tiny amounts of interstitial fluid needed to analyze electrolyte levels but could not draw enough fluid to make more complicated medical tests practical. The new method's larger draws could be more effective in rapidly measuring exposure to chemical and biological warfare agents as well as diagnosing cancer and other diseases.

Machine learning-detected signal predicts time to earthquake

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Machine-learning research published in two related papers today in Nature Geosciences reports the detection of seismic signals accurately predicting the Cascadia fault's slow slippage, a type of failure observed to precede large earthquakes in other subduction zones.

Arctic ice model upgrade to benefit polar research, industry and military

DOE/Los Alamos National Laboratory

An update for an internationally vital sea-ice computer model developed at Los Alamos National Laboratory with several collaborating groups, called CICE version 6.0, is being released this week, a timely tool that supports more accurate forecasting of ice occurrence and global climate modeling.
