World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices use fluctuations in the energy ...

Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and ...

If you have ever sat in a quiet room with a wall clock nearby, you have probably noticed the steady tick-tock rhythm. It is such a common sound that most people barely notice it, yet the reason behind ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

A new book explores what makes our internal clocks tick and how we can reset them for the better. Science journalist Lynee Peeples spoke with some 240 scientists, chronobiologists, athletes, ...
