Discovered by Professor John Nye in Bristol over 35 years ago, polarisation singularities occur at points where the polarisation ellipse is circular, with other polarisations wrapping around them. In 3 dimensions, these singularities occur along lines, in this case creating knots.  The detectors created by ATI researchers are able to achieve high sensitivity levels that strongly compete with current technologies, while still operating at low voltages, as well as over the whole X-ray energy range spectrum.  There's nothing quite like an ice cream on a hot day, and eating it before it melts too much is part of the fun.  Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays.  In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.
