Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by ...

If your mornings already feel too early, brace yourself. Daylight Saving Time is back next month, and it will bring later ...

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 ...

It's far too easy to let keeping your home clean to slide, and if you're not careful you'll end up with a situation that's spiralled completely out of control. Common wisdom suggests tackling issues ...

It's far too easy to let housework slide, and before long, you're facing a mountain of mess that's spiralled out of control. While tackling issues promptly beats leaving them to accumulate, everyday ...

Why have just one technological breakthrough when you can have two at the same time? The Royal Navy has installed for the first time a quantum clock into its XV Excalibur robotic submarine for ...

Optical atomic clocks just took a clean step forward. An MIT team reports a method that cuts quantum noise and lets a clock resolve twice as many ticks as before. The work centers on ytterbium atoms ...

Atomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...
