Mold behind your walls could make you sick, but it's tough to know for sure if it's there.  Punching holes in walls, or tearing them down, is an expensive and messy way to find out.  Researchers at Georgia Tech think they can make the job easier and cheaper.  Project leader Victor DeJesus says they've already engineered a laboratory device that can detect—and maybe even precisely map—mold growing on the other side of a wall.  It uses high-resolution radar that produces unique signals when bouncing off mold.  Now the main challenge is to scale it down to a size that can be carried around.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
