An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters.

Caesium fountains are more accurate than "normal" atomic caesium clocks, because in fountains the caesium atoms are cooled down with the aid of laser beams and come ever slower - from a rapid velocity at room temperature to a slow "creep pace" of a few centimetres per second at a temperature close to the absolute zero point.
