These radical new devices keep time using fluctuations in the energy states of an atom’s nucleus, rather than those of its ...

Pinky time is a hand exercise that’s trending on social media as a way to slow cognitive decline. Some evidence suggests hand exercises can stimulate the brain, but there’s no research pointing to ...

Two teams of physicists have made the world’s first nuclear clocks. These radical new devices use fluctuations in the energy ...

This important work introduces an integrated open-source platform for behavioral acquisition and pose estimation that substantially improves the accessibility and speed of real-time animal tracking ...

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 ...

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. But when combined with quantum ...

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.

In July 2008, a 41-year-old Dutch woman developed a rapidly progressing illness after visiting Python Cave, a shallow groove cut into the Maramagambo Forest in Uganda that is home to thousands of ...
