Earth’s rotation is speeding up. This summer, our planet will spin faster than usual, creating the shortest day since records ...

In the final analysis, by showing that 10 heterogenous clocks across three continents could agree with each other to within a ...

So far, the shortest day ever recorded was July 5, 2024, when Earth rotated 1.66 milliseconds faster than usual. This year, ...

While that tiny time difference is imperceptible to humans, it represents part of a broader pattern that has left scientists ...

Global positioning systems that support mapping programs are a prime example of how basic science can lead to unforeseen but ...

Quantum clocks break energy limits, unlocking ultra-precise timekeeping with far-reaching tech, AI, and navigation impacts.

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

Iran reacted immediately, saying it will establish a new enrichment facility “in a secure location” and that “other measures ... resolution,” the Iranian Foreign Ministry and the Atomic Energy ...

One example is the atomic clock, which uses the quantum properties of atoms to measure time much more accurately than would be possible with conventional clocks.

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

From space, the Atomic Clock Ensemble in Space will link to some of the most accurate clocks on Earth to create a synchronized network, which will support tests of fundamental physics.
