Scientists demonstrate a nuclear clock using thorium-229
Original: A nuclear clock synchronized to 229Th
Researchers have reported a nuclear clock synchronized to the thorium-229 isotope, a long-sought advance in precision timekeeping. Unlike atomic clocks, which use electron transitions, a nuclear clock taps transitions inside the atomic nucleus, promising greater stability and resistance to environmental disturbance. The result, published in Nature, is being discussed as a milestone with potential applications in fundamental physics tests and precision navigation.
Why now: It is a significant scientific first in precision timekeeping, following recent breakthroughs with thorium-229's nuclear transition.
