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

Atomic clocks and our computer networks are the new, far superior form of time measurement, but we’re forcing them to keep in sync with this older form of measurement,” remarks Dr. David Gozzard, an ...

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, ...

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

Due to the way Earth's rotation is measured, Wednesday, July 9 will technically lose time. Here's why you most likely won't ...

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

Iran's stockpile of uranium enriched at 60 percent would be enough to make several relatively unsophisticated nuclear weapons ...

Global positioning system (GPS)-based phasor measurement units (PMUs) are increasingly deployed in the power system in order to monitor the grid status in real time. Nevertheless, GPS receivers inside ...

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

In this interview, Ian Stewart, executive director of the James Martin Center for Nonproliferation Studies in Washington, DC, says that, in the aftermath of the bombing of Iranian nuclear facilities, ...
