Park Electrochemical Corp. (Melville, NY) offers Aeroglide™ surfacing film for aircraft composite parts fabrication. The film is designed to improve the surface finish of aircraft composite parts, and reduce or eliminate secondary surface finishing operations prior to painting. The film is compatible with most epoxy prepregs, and...

Moxtek (Orem, UT) offers absorptive wire-grid polarizers for the blue, green, and red channels. The polarizers are designed for narrow-band applications and where back reflection is a concern. They are designed to transmit the p-polarization and absorb the s-polarization of incident light, rather than reflecting the unwanted...

Dr. William Ko joined NASA’s Dryden Flight Research Center in 1977 after receiving a PhD in aeronautics from California Institute of Technology and conducting research at Southwest Research Institute in San Antonio, Texas. An...

A sniffing-based device developed at the Weizmann Institute of Science in Israel may enable disabled people to navigate wheelchairs or communicate with loved ones. The system identifies changes in air pressure inside the nostrils and translates these into electrical signals. In the future, researchers predict that this...

A new vaccine-delivery patch based on hundreds of microscopic needles that dissolve into the skin could someday allow people without medical training to painlessly administer vaccines. The new patch could also help prevent unsafe reuse of hypodermic needles, particularly in parts of the world with poor medical infrastructure.

As the demand for greener appliances and consumer products soars across the globe, and energy savings becomes a global phenomenon (and necessity) in residential and commercial environments, solar and wind power technologies have begun to proliferate in cities and...

This week's question concerns brain scans and the legal system. In 2008 a judge in India convicted a woman of murdering her fiancee based partly on brain scan evidence that gauged her ability to remember details of the crime. And in the US, fMRI scans have already found their way into courtrooms...

Developed at the University of Sussex, the Electric Potential Sensors (EPS) are the first electrical sensors that can detect precisely the electrical activity of the heart without direct resistive contact with the body. The new sensors can detect a heartbeat up to a meter away, and make monitoring a patient's heartbeat easier...

This week's question concerns the recent discovery of Russian spies still operating in the US. In June, authorities uncovered a Russian spy ring of 10 individuals operating in New York and Cambridge. Last week, the US and Russian governments completed a "spy swap" in Vienna. ...
