Nuclear Fusion Startup Claims Mercury-to-Gold Transmutation and Isotope Enrichment

San Francisco-based nuclear fusion startup Marathon Fusion has announced it has achieved mercury-to-gold transmutation at a rate reportedly ten times higher than the previous record set by CERN in 2025. The company also claims to have enriched isotopes using a plasma centrifuge, surpassing a 40-year-old Soviet record. These claims involve nuclear transmutation, a process that alters an atom's nucleus to produce a different element or isotope.
