A new paper from the same team, led by Attila Krasznahorkay at the Atomki institute in Hungary, now reports another anomaly, in a similar nuclear transition, that could also be explained by the same hypothetical particle.  These new subatomic particles could either be made of six heavy quarks (charm and bottom) or heavy and strange quarks.  Argonne scientists look to 3-D printing to ease separation anxiety, which paves the way to recycle more nuclear material.  Recently, scientists suggested switching from electron to nuclear transitions that may considerably increase the precision of clocks due to higher frequency.  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.  Researchers characterize the rotational jiggling of an optically levitated nanoparticle, showing how this motion could be cooled to its quantum ground state.  Researchers have created quantum states of light whose noise level has been "squeezed" to a record low.  An elliptical light beam in a nonlinear optical medium pumped by "twisted light" can rotate like an electron around a magnetic field.
