(NEXSTAR) – There was bipartisan legislation, committee hearings, efforts from multiple states, and even presidential support, but the U.S. still observed the beginning and end of daylight saving time ...

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 ...

Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...

Some members of the maker community are distraught about Arduino’s new terms of service (ToS), saying that the added rules put the company’s open source DNA at ...
