nuclear clocks

Researchers in Vienna and Beijing have built the first working nuclear clocks based on the thorium-229 isotope, marking the debut of a new class of timekeeping devices. Unlike atomic clocks, nuclear clocks probe energy transitions inside the atomic nucleus, promising greater stability and potential tests of whether fundamental constants of physics change over time.

Scientists have announced the first self-regulating nuclear clock, built around the thorium-229 transition, a breakthrough in precision timekeeping. Because the clock is so sensitive to changes in fundamental constants, researchers say it could be used to detect dark matter, whose presence might subtly alter these constants over time.

Physicists have reported the first nuclear clocks, a new class of timekeeping devices that use energy transitions in an atomic nucleus rather than the electron transitions used in atomic clocks. Because nuclei are far less sensitive to external disturbances, the technology promises dramatically greater precision. Researchers say the achievement opens a competition to refine the clocks and test fundamental physics.

Physicists report a long-sought breakthrough in nuclear clock technology, using light to drive a transition in an atomic nucleus — a step toward timekeeping devices far more precise than today's best atomic clocks. Such clocks could probe fundamental physics, test whether constants of nature change over time, and enable new precision measurements. Researchers describe the advance as the moment the nuclear clock concept moves from theory toward reality.

Scientists have announced the arrival of nuclear clocks, a new type of timekeeping device that probes energy transitions inside atomic nuclei rather than electron shells. Unlike existing atomic clocks, nuclear clocks could be far more stable and may test whether fundamental constants of physics change over time. Researchers say the technology opens a new window onto the basic laws of nature.

Scientists in Vienna and Beijing have built the first working nuclear clocks based on thorium-229, a long-pursued breakthrough in precision timekeeping.

Researchers and science commentators are discussing what the milestone means for the future of measurement science.

Scientists have unveiled the world's first nuclear clocks, a new class of timekeeping device that measures time using energy transitions in an atomic nucleus rather than electron orbitals as in conventional atomic clocks. Researchers say the technology could eventually exceed today's most accurate clocks in precision and open new ways to probe fundamental physics, and it is drawing wide attention in science media.
