Math and computer science researchers have long known that some questions are fundamentally unanswerable. Now physicists are ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

A more precise definition of the second is crucial to all sorts of physical measurements – but to get there, scientists have to pack up their extraordinarily fragile optical clocks and take them on to ...

This created a stable compound, allowing the researchers to use X-ray absorption spectroscopy to measure the length of the ...

Then there’s “chokable snow,” a term for powder so deep that it flies up into your mouth. The list goes on. One lift ride, he ...
