It was an interesting week in physics as researchers delved into the question of why the measurements of the gravitational constant vary so much. The latest theory suggests that it is not likely attributable to systematic ...
Researchers at the University of Rochester's Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.
