Japanese brand Balmuda has created a white-noise-producing alarm clock with a glowing dial to reduce smartphone use at ...

Just about every electronic device has some silicon semiconductors inside these days—from transistors to diodes to integrated circuits. [Charles] is trying to build a “No-Silicon digital clock” that ...

A huge breakthrough decades in the making was made just a few months ago, and already scientists are realizing its potential: A measurement of the gap between the quantum energy states of a thorium ...

Chinese scientists have engineered a clock so accurate it could lead to a redefinition of the second and an ultraprecise ...

Nuclear clocks would measure time based on changes inside an atom's nucleus, which would make them less sensitive to external disturbances and potentially more accurate than atomic clocks. These ...

Liam Thompson upgrades his alarm clock to create a more fun and functional device.

Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...

A powerful laser shines into a jet of gas, creating a bright plasma and generating ultraviolet light. The light leaves a visible white line as it interacts with leftover gas in the vacuum chamber.
