How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new geological "rock ...

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

When a series of back-to-back atmospheric rivers hammered the West Coast in December 2025, the storms killed at least five ...

The strontium optical lattice clock is one of the most accurate timepieces ever made, capable of measuring seconds to 19 decimal places.

Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise global time standard. The new optical clock is so accurate that it loses or ...

Mazama Energy Inc. is set to begin geothermal exploration work near Newberry Volcano in central Oregon starting December 22, ...
