Scientists have traced a decades-old gamma-ray mystery to hidden magnetic transitions inside atomic nuclei. For decades, nuclear physicists have faced a puzzling question: why do some atomic nuclei release far more low-energy gamma rays than expected? A new study led by the Facility for Rare Isotope Beams (FRIB), with contributions from scientists at Lawrence Livermore [...]

Princeton’s PACMAN AI can control fusion plasma in milliseconds and predict dangerous instabilities before they start. In some fusion energy systems, particles can reach temperatures hotter than the center of the Sun. The challenge is keeping that extreme plasma under control, because disturbances can develop within just a few thousandths of a second, much faster [...]
