The clock debate pops up every year as Americans ask the same question: Are we still changing clocks — or is daylight saving time about to disappear? Here's when and what to know about this year's ...

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices keep time using fluctuations in the energy states of an atom’s nucleus, rather than those of its electrons ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

For the first time, scientists used an atomic nucleus as a clock. The world’s most precise timepieces are made using atoms, specifically their electrons. But clocks based on atomic nuclei — protons ...

A powerful molecular clock calibrated using data on gene activity from thousands of individuals can predict biological ageing in rodents, monkeys and humans — and time to death in people 1. “Even if ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same ...

OpenAI has announced three new real-time voice and audio API models, giving developers more options for building live voice agents, translation tools, and speech-to-text apps. The new lineup includes ...

May 7 (Reuters) - OpenAI introduced three audio models for its developer platform on Thursday, aiming to make voice-based software agents more ‌conversational and capable of completing tasks in real ...

HOBOKEN, NJ., April 20, 2026 — Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein’s theory of relativity, time is not absolute: its passage depends on motion and gravity.

As part of his Real Time series, artist Maarten Baas has created The People’s Clock, a timepiece that lives in Amsterdam’s Schiphol airport. To create the clock’s “workings”, Baas recorded more than ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

What started as a creative build challenge turned into a real test of whether ancient timekeeping methods could still hold up under pressure. By making an hourglass, sundial, water clock, and candle ...
