Physicists have demonstrated a novel atomic clock design that combines near-continuous operation with strong signals and high stability, features not previously found together in a single type of next ...

The circadian clock system allows the organisms to adjust to periodical changes of geophysical time. Today, increasing evidence show that disturbances in our internal clocks stemming from frequent ...

This story is part of a series on how we make time—from productivity hacks and long walks to altering the function of our own circadian clocks. Before there was electricity or the internet or screens ...
