New study shows nanoscale pendulum coupling

In 1665, Lord Christiaan Huygens found that two pendulum clocks, hung in the same wooden structure, oscillated spontaneously and perfectly in line but in opposite directions: the clocks oscillated in anti-phase. Since then, ...

Behavior of ultra-cold atoms and polar molecules modeled

Theoretical physicist Ana Maria Rey uses the computer, as well as pencil and paper, to develop mathematical models that describe the behavior of ultra-cold atoms. The idea is to use these systems to learn more about condensed ...

At the heart of the circadian clock

(Phys.org) —Cellular processes in most organisms are regulated by an internal clock, and proteins called cryptochromes are at the core of its central oscillator. The three dimensional structures of cryptochromes from mouse ...

The Antikythera time machine

Leonardo da Vinci may have left behind sketches of helicopters, tanks and submarines but it is rare that we find actual artifacts that seem so way ahead of their time. Almost like a science fiction tale of archaeologists ...

Circadian clocks in a blind fish

Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A ...

A new EU project on ultra-precise atomic clocks

Jan Thomsen, Associate Professor and head of the Ultracold Atoms research group at the Niels Bohr Institute is part of a grant of 14 million kroner to participate in an EU project to develop ultra-precise atomic clocks that ...
