Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...
