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."

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
