Aerospace test at Sandia goes green with alternative to explosives

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories has successfully demonstrated a new, more environmentally friendly method to test a rocket part to ensure its avionics can withstand the shock from stage separation during flight.

Machine-learning earthquake prediction in lab shows promise

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

By listening to the acoustic signal emitted by a laboratory-created earthquake, a computer science approach using machine learning can predict the time remaining before the fault fails.

DNA detectives crack the case on biothreat look-alikes

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Biological "detectives" are tracking down biothreats such as the bacteria that causes tularemia ("rabbit fever"), but they constantly face the challenge of avoiding false positives.

Biofuels from bacteria

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories is helping a Bay Area company better understand whether cyanobacteria can be grown for biofuels on a large scale.

Superconductivity research reveals potential new state of matter

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common.

Unique imaging of a dinosaur's skull tells evolutionary tale

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Researchers using Los Alamos' unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.

Balloons and drones and clouds; oh, my!

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Last week, researchers at Sandia National Laboratories flew a tethered balloon and an unmanned aerial system, colloquially known as a drone, together for the first time to get Arctic atmospheric temperatures with better location control than ever before.

The good, the bad and the algae

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories is testing whether one of California's largest and most polluted lakes can transform into one of its most productive and profitable. Southern California's 350-square-mile Salton Sea has well-documented problems related to elevated levels of nitrogen and phosphorus from agricultural runoff. Sandia intends to harness algae's penchant for prolific growth to clean up these pollutants and stop harmful algae blooms while creating a renewable, domestic source of fuel.

Study reveals exactly how low-cost fuel cell catalysts work

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

New work at Los Alamos and Oak Ridge national laboratories is resolving difficult fuel-cell performance questions, both in determining efficient new materials and understanding how they work at an atomic level. The research is described this week in the journal Science
