Singapore team builds world's most accurate atomic clock, surpassing US and China

A Singaporean research team has developed a lutetium-ion atomic clock that loses one second every 260 billion years, about four times more accurate than the previous record holder from China. This marks a significant scientific milestone in timekeeping precision, with potential implications for GPS, telecommunications, and fundamental physics research. The achievement underscores Singapore's growing capability in advanced metrology, though the practical applications remain in early stages.
