In an underground vault enclosed by six-foot concrete walls and accessed by a rolling, 25-ton concrete-and-steel door, University of California, Berkeley, students are making neutrons dance to a new tune: one better suited to producing isotopes required for geological dating, police forensics, hospital diagnosis and treatment.  Polymer gels, a gel type with unique properties, have piqued the interest of researchers because of their potential uses in medical applications.  Tensorial neutron tomography promises new insights into superconductors, battery electrodes and other energy-related materials.  CERN's nuclear physics facility, ISOLDE, has minted a new coin in its impressive collection of isotopes.  In the case of several light nuclei, experimental confirmation of the individualism or family nature of nucleons will now be simpler, thanks to predictions presented by Polish physicists from Cracow and Kielce.  The identification of the magic number of six provides an avenue to investigate the origin of spin-orbit splittings in atomic nuclei.  Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus.  The process of the sticking together of quarks, called hadronisation, is still poorly understood.  In experimental campaigns using the OMEGA EP laser at the Laboratory for Laser Energetics (LLE) at the University of Rochester, Lawrence Livermore National Laboratory (LLNL), University of California San Diego (UCSD) and Massachusetts Institute of Technology (MIT) researchers took radiographs of the shock front, similar to the X-ray radiology in hospitals with protons instead of X-rays.  Researchers generate proton beams using a combination of nanoparticles and laser light.  Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way.
