Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with ...

Because the moon has less gravity than Earth does, time passes slightly differently there. This effect was first predicted by ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC ...
