Meet the “nuclear” clock: a device that marks the passage of time via minute signals from the nucleus of an atom. A team of researchers led by scientists at JILA, a joint institute of the National ...

WASHINGTON — Researchers have demonstrated a new optical atomic clock that uses a single laser and doesn’t require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks ...

Optical clocks are highly precise timekeeping devices that measure time by tracking the oscillations of light, as opposed to ...

Dark matter is a hypothetical form of matter believed to be everywhere, outnumbering regular matter (what we're made of) 5-to-1. It doesn’t emit or interact with light, so it is invisible to our ...

The exhibition will run for a year, and access to it is included in the price of a regular ticket to the centre. Read more at ...

EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

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 ...

Frequency Electronics, Inc. (FEI), a provider of precision timing and frequency technology, clarified a previous statement made during itsearnings callregarding anticipated revenue from its new TURbO ...
