Trump signs executive orders to boost nuclear power, speed up approvals The orders take authority away from the independent safety agency that has regulated the U.S. nuclear industry for decades.

By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time.

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch.

A technological innovation could revolutionize the precision of navigation systems. A tiny device, shaped like a comb, promises to deliver unparalleled accuracy in the field of positioning.

The world’s best atomic clocks rely on the energy transitions of electrons that orbit an atomic nucleus. These clocks are so accurate that they gain or lose only a second every 40 billion years.

A recent breakthrough has paved the way for timekeeping even more precise than the measurements performed by atomic clocks.
