Marathon Fusion Claims Breakthrough in Mercury-to-Gold Transmutation, Beating CERN's Record

San Francisco-based nuclear fusion startup Marathon Fusion has announced a significant achievement, claiming to have demonstrated mercury-to-gold transmutation at a rate 10 times higher than the record set by CERN in 2025. The company also reported enriching isotopes in a plasma centrifuge, surpassing a 40-year-old Soviet record. These experiments involve nuclear transmutation, changing an atom's nucleus to produce a different element or isotope.
