Super Strong Magnetic Fields Leave Imprint on Nuclear Matter
Brookhaven National Laboratory

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter. The evidence comes from measuring the way differently charged particles separate when emerging from collisions of atomic nuclei at this DOE Office of Science user facility.

Scientists have confirmed possible evidence of a new elementary particle, the sterile neutrino. The results from the Baksan Experiment on Sterile Transitions (BEST) found that the germanium 71 yield was 20% to 24% lower than expected based on the intensity of the neutrino source and on scientists’ knowledge of how neutrinos are absorbed. This is consistent with earlier results on the so-called gallium anomaly.

New calculations predicting the spatial distributions of the charges, momentum, and other properties of the quarks within protons found that the up quarks are more symmetrically distributed and spread over a smaller distance within the proton than the down quark. The results imply that these two types of quarks contribute differently to a proton’s properties.

In APL Materials, researchers tested a molecular energy harvesting device that captures the energy from the natural motion of molecules in a liquid. Their work showed molecular motion can be used to generate a stable electric current. To create the device, they submerged nanoarrays of piezoelectric material in liquid, allowing the movement of the liquid to move the strands like seaweed waving in the ocean, except in this case the movement is on the molecular scale, and the strands are made of zinc oxide. When the zinc oxide material waves, bends, or deforms under motion, it generates electric potential.
