(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Two cutting-edge atomic clocks — the most accurate ever ...

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick — not ...

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 ...

Officials said the error is likely too minute for the general public to clock it, but it could affect applications such as critical infrastructure, telecommunications and GPS signals.
