A previously unknown class of wave has been discovered in the Antarctic atmosphere by a team of researchers from the University of Colorado Boulder in the US. These gravity, or buoyancy, waves appear ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...
