Nuclear Science
Nuclear physicists at the University of Tennessee have made three key findings about the rapid neutron-capture process that forms heavy elements like gold in stellar events. Their research, conducted at CERN's ISOLDE facility, clarifies how unstable atomic nuclei decay. The results, published in Physical Review Letters, could refine models of element formation in the universe.

Physicists at MIT have developed a new method using molecules to investigate the interior of atomic nuclei, employing electrons as messengers in a tabletop setup. By studying radium monofluoride, they detected subtle energy shifts indicating electron interactions inside the nucleus. This approach could help explain the universe's matter-antimatter imbalance.
