Working on X-ray vision

              Dina Katabi, a 42-year-old professor of computer science and electrical engineering at the Massachusetts Institute of Technology, is working on a way to use Wi-Fi radio signals to track people through walls, similar to X-ray vision. The signals traverse through walls and obstacles and reflect off a human body. She was one of the 24 recipients of the MacArthur Fellow, AKA the Genius Awards.\

          To me this is a big step in technology. They say they cant see the silhouette of a person, but they see them like a blob, which they can use to trace how the person is moving behind a wall. This will expand ways to find hidden people or for reconnaissance.
