Researchers are testing the feasibility of using radar technology to detect mold behind gypsum wallboard. A common problem, hidden mold can cause serious structural damage and health problems before homeowners discover it.
Researchers are testing the feasibility of using radar technology to detect mold behind gypsum wallboard. They are using a signal processing algorithm and high-sensitivity, laboratory-size radar system recently developed by the Georgia Tech Research Institute.

Hoping to develop a non-destructive and less expensive method than is now available to detect mold behind walls, Georgia Tech Research Institute (GTRI) scientists are collaborating with humidity control expert Lew Harriman of Mason-Grant Consulting in a two-year feasibility study primarily funded by the U.S. Department of Housing and Urban Development (HUD) through its Healthy Homes Initiative. The Air-Conditioning and Refrigeration Technology Institute in Washington, D.C., and Munters Corporation in Norcross, Ga., are also providing funds for the study.
"Mold is a common problem, especially in humid, southern climates, but people are often not aware of it because its occurring behind a painted or wallpapered wall," said GTRI research scientist Victor DeJesus. "Then its too late when they realize it. The wallboard must be replaced."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
