Washington State University researchers have created a multi-functional smart material that changes shape when subjected to heat or light; the material then assembles and disassembles itself.

This week's Question: On July 11th, the convenience store chain 7-Eleven partnered with drone startup Flirtey to make the first commercial delivery – a chicken sandwich, donuts, coffee, candy, and Slurpees – to a private residence in Reno, Nevada. Many companies, like Amazon and Google, are exploring the use of...

This week's Question: In the paper "Friend or Foe?: Your Wearable Devices Reveal Your Personal PIN" scientists from Binghamton University and the Stevens Institute of Technology combined data from embedded sensors in wearable technologies, such as smartwatches and...

This week's Question: The Dallas Police Department used a bomb-disposal robot armed with a brick of C-4 explosives to kill the gunman who had shot and killed five Dallas police officers. The use of armed robots by police is worrisome to those who fear they could be used on American streets for crowd control.

NASA’s Marshall Space Flight Center has developed a unique apparatus ideal for use in nondestructive testing (NDT) of hermetic seals of containers or instrumentation. The device is capable of detecting both large and small leaks and can be calibrated to characterize the...

Traditional methods of flight flutter testing analyze system parameters such as damping levels that vary with flight conditions to monitor aircraft stability. In the past, the actual flight envelope developed for aircraft operation was essentially determined only by flight testing. The edges of...

Typically, mechanical test data has been reviewed and processed using a combination of Excel, PDF Viewer, MATLAB, and other tools. TestEVAL provides a central tool for all these tools, and enhances their capability. Having been developed in Python, it is expendable and portable. It uses no...

High-resolution submillimeter-wave spectroscopy is based on the heterodyne principle, where the incident signal is down-converted to a low intermediate frequency (IF) by nonlinear mixing with a local oscillator (LO) signal. The IF difference...

NASA has developed a novel hybrid supercapacitor system utilizing vertical graphene as an electrode material grown directly on collector metals using a plasma enhanced chemical vapor de - position. Supercapacitors are an alternative to batteries for energy storage, offering high power density and...
