New Algorithm Reveals Underground Water Levels

Researchers from Stanford University have used satellite data and a new computer algorithm to gauge groundwater levels in Colorado’s San Luis Valley agricultural basin. The technique "fills in" underground water levels in areas where quality data had been previously unavailable.

Air Traffic Lab Answers Questions About Future Flying

The holiday season is upon us and that means crowded airports and delayed flights. Researchers at NASA's Langley Research Center are working to change that. They are conducting studies to help reshape the future of American air travel in a brand-new Air Traffic Operations Laboratory (ATOL). They are studying the Next Generation Air Transportation System, a new national airspace technology being implemented by the Federal Aviation Administration.

Foldable Material Can Support Many Times its Weight

Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration, and radio frequency shielding in technology from portable electronics to coaxial cables.

Webb Telescope’s Heart Survives Deep-Freeze Test

After 116 days of being subjected to extremely frigid temperatures like those in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA’s Goddard Space Flight Center.

Sensor Uses Radio Waves to Detect Subtle Pressure Changes

Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries. The underlying technology has such broad potential that it could one day be used to create skin-like materials that can sense pressure, leading to prosthetic devices with the electronic equivalent of a sense of touch. In one simple demonstration they used this wireless pressure sensor to read a team member’s pulse without touching him.

3D Audio Research Helps Make Cockpit Safer

Imagine yourself in a cockpit, flying a mission, listening to a multitude of critical voices delivering vital messages, all at the same time and from the same direction. Now imagine the same environment, except that the voices are now distinct and separate. The Air Force Research Laboratory (AFRL) has developed 3D sound technology that creates a sound environment that mimics the way the human body receives aural cues, much like 3D movies create the perception that the viewer is part of the movie.
