First Thorium Nuclear Clocks Start Ticking in Vienna and Beijing

Original: In Vienna and Beijing, the first (thorium) nuclear clocks begin to tick

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.

Why now: The first-ever operation of nuclear clocks is a landmark scientific breakthrough in precision timekeeping.
