Rival Teams Build First Nuclear Clocks, Then Immediately Search for Dark Matter

Research teams at TU Wien in Austria and Tsinghua University in China have independently built the first nuclear clocks using thorium-229, achieving a milestone in precision timekeeping. The Vienna group immediately used their clock to run the first dark matter search employing a nuclear frequency reference, setting new constraints on dark matter interactions.
