New Research Finds Cause of Alloy Weakness

Sometimes calculations don’t match reality. That’s the problem that has faced materials scientists for years when trying to determine the strength of alloys. There has been a disconnect between the theoretical strength of alloys and how strong they actually are. Why?

NASA Takes Aviation Research to the ‘Max’

NASA and the German Aerospace Center (DLR) are studying what happens with engine performance, emissions, and contrail formation when using different types of fuels in jet engines. The international collaboration uses Germany’s Advanced Technology Research Aircraft (ATRA) A320 aircraft burning alternative biofuels, while NASA’s fully instrumented DC-8 Flying Laboratory trails a safe distance behind, sampling and analyzing gases and particles within the ATRA’s wake.

‘Quantum Radio’ May Aid Communications Indoors, Underground, Underwater

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground. The technology may help mariners, soldiers and surveyors, among others.
