Experiments Differentiate Between Underground Nuclear Tests and Earthquakes

Sandia National Laboratories researchers, as part of a group of National Nuclear Security Administration scientists, have wrapped up years of field experiments to improve the United States’ ability to differentiate earthquakes from underground explosions, key knowledge needed to advance the nation’s monitoring and verification capabilities for detecting underground nuclear explosions.

Sensor Could be Game-Changer in Airline Safety

A new sensor, that can detect ice accumulation in real-time, might be a game-changer when it comes to airline safety and efficiency. The sensor could detect the precise moment when ice begins to form on a surface. Due to their high sensitivity, low power, ease of fabrication, and planar profile, microwave resonators were used.

Portable Gas Detection Shrinks to New Dimensions

A sensor for detecting toxic gases is now smaller, faster and more reliable, setting it up for integration into a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also rapidly detect airborne toxins where they occur, providing key information to help emergency personnel respond safely and effectively to an incident.

Operating at the Speed of Thought

When a cyber-warrior defends a complex computer network, or a pilot commands a team of unmanned vehicles, or a submarine officer interacts with intricate sensor systems, they are often limited by conventional interfaces: their fingers, eyes and ears. And while commercial technology has opened new possibilities for controlling complex systems — touch screens, mixed reality and voice control — taking full advantage of these increasingly fast, smart and sophisticated systems will require direct interface with the brain.

Army Turns to Smart Technology to Protect Military Installations

Assistant Secretary of the Army for Installations, Energy and Environment Alex Beehler doesn't need proof of threats to military and government installations. He is reminded every day. His office sits next to the point of impact where American Airlines Flight 77 crashed into the western side of the Pentagon nearly 18 years ago during the 9/11 attacks. As the variety and complexity of threats continue to increase, security at U.S. military installations has taken increased importance in the years since 9/11.

NASA to Advance Unique 3D Printed Sensor Technology

Mahmooda Sultana recently won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and then transmitting that data via a wireless antenna — all from the same self-contained platform that measures just two-by-three-inches in size.

MAPS-Enabled Countermeasures Defeat Threats in U.S. Army Field Tests

In a series of live-fire tests, systems equipped with MAPS-enabled countermeasures defeated 15 out of 15 anti-tank guided missiles by jamming their signals, causing them to fly off-target.

NIF Experiments Support Warhead Life Extension

It was a normal morning for design physicist Madison Martin at Lawrence Livermore National Laboratory (LLNL). At 7:45 a.m., she settled into her classified workstation with a cup of tea to check the results of a numerical calculation she ran overnight. If the calculations proved correct, the experiment she was designing on the National Ignition Facility (NIF) would deliver the data her colleagues needed to verify that a refurbished nuclear warhead would perform as expected.
