A clock based on radioactive thorium atoms realises a long-held ambition, demonstrating a technology that could eventually beat the accuracy of today’s best atomic clocks ...

Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and are protected in a crystal. Creating a nuclear clock is “a dream come ...

Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study suggests trapped-ion atomic clocks could detect quantum superpositions of time, opening a path toward uniting quantum ...

For the first time, scientists used an atomic nucleus as a clock. The world’s most precise timepieces are made using atoms, specifically their electrons. But clocks based on atomic nuclei — protons ...

This Week in Science: A world first, a strange human pattern, and much more! We start with something you might do every day without much thought: walking. It turns out humans may not move quite as ...

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...
