(PhysOrg.com) -- Researchers at the University of Utah, USA, have discovered that variations in signal strengths in wireless networks can be used to "see" movements of people on the other side of walls or doors.
Pure diamond consists of carbon atoms in a perfect crystal lattice. But remove a few carbons and swap some others for nitrogen, and you get a diamond with special quantum-sensing properties. These properties are useful for ...
