The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In A Nutshell The world’s most precise clocks are changing how we understand ...

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 ...

This has now paved the way for a multi-ion optical ytterbium clock that combines the high accuracy of single-ion clocks with ...

Atoms that occur in nature interact with the electromagnetic field at a single point, allowing scientists to make certain assumptions about energy levels with point-like references. However, ...

Some customers placed orders for an Ariel Atom 4R before the car was even officially announced. Such was the popularity of 2013’s Atom 3.5R and the nous of its fans, it was naturally assumed there ...

IT seems to be generally assumed that diplogen will always react more slowly than hydrogen. As I may partly be responsible for this view 1, I should like to point out that this is not always correct.

Researchers at Nano Life Science Institute (WPI-NanoLSI) and the Cancer Research Institute at Kanazawa University have uncovered how targeted lung cancer drugs alter the shape and behavior of a key ...
