Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks ...

“Quantum clocks running at the smallest scales were expected to lower the energy cost of timekeeping, but our new experiment ...

Forty percent of babies in the U.S. are born to unmarried mothers. Increasingly, those moms are over 30, at a time when teen ...

This alarm clock is controlled by the RTC described in another project, which ensures automatic time setting. The display adjusts according to ambient light, ensuring glare-free readability day and ...

STATEN ISLAND, N.Y. — When Daylight Saving Time ends on Nov. 2, we have to set our clocks back one hour. This happens every fall, giving us an extra hour of sleep, but costing us an hour of daylight ...

Abstract: Time analog-to-digital converters (TADs) based on the power-supply voltage dependence of CMOS gate propagation delay time can be constructed solely of CMOS digital circuits and are ...

Abstract: The architecture and algorithms for the first all-digital radio-controlled clock receiver for the new WWVB broadcast format are proposed. To address the potentially low signal-to-noise ratio ...

Cortisol is a hormone that plays an active role in metabolic health, blood pressure control and immune response. But, perhaps what cortisol is most known for is its handling of stress.

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...
