Astronomers can't see dark matter directly, but know it's there: its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence Livermore National Laboratory (LLNL) is pursuing evidence of these particles that exist beyond the standard model of physics. In a new experimental campaign called Magnetometry for Neutrino physics (Magneto-ν), scientists at LLNL are searching for the sterile neutrino using nuclear beta decays of plutonium-241. This hypothetical neutrino species is significantly heavier than

Sandwiched between the electrolyte and electrodes in a lithium-ion battery is a remarkably thin layer of material that strongly dictates battery performance and durability: the interphase. Although typically only a few to tens of nanometers thick, interphases are among the least understood components of an operating battery cell. Their complex and constantly evolving structures make it challenging to determine how their atomic features and microscopic variations translate into macroscopic battery performance. In a recent study, published in Advanced Energy Materials, researchers at

It has been a long-standing mystery in nuclear physics: why do the nuclei of some atoms emit more low-energy gamma rays than they should? The answer can be found in a new study from an international scientific team led by the Facility for Rare Isotope Beams (FRIB) and including authors from Lawrence Livermore National Laboratory (LLNL). Published in Nature, the work sheds light on the internal structure of atomic nuclei and has far-reaching implications for national security and astrophysics. Gamma rays are a type of electromagnetic radiation like visible light and radio waves. Atomic
