Physicists at Chalmers University of Technology now understand why it is not possible to increase the speed beyond a certain limit—and know the circumstances in which it is best to opt for a different route.  Manipulating light in a variety of ways—shrinking its wavelength and allowing it to travel freely in one direction while stopping it cold in another—hyperbolic metamaterials have wide application in optical communications and as nanoparticle sensors.  A new way of enhancing the interactions between light and matter, developed by researchers at MIT and Israel's Technion, could someday lead to more efficient solar cells that collect a wider range of light wavelengths, and new kinds of lasers and light-emitting diodes (LEDs) that could have fully tunable color emissions.  A team of researchers at the Center for Relativistic Laser Science, within the Institute for Basic Science (IBS) have developed a method to measure the shape of laser pulses in ambient air.  Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays.
