A little context would help:

Japanese researchers have created super-accurate optical lattice clocks
They are 1,000 times more precise than the most accurate atomic clocks
They are made using super-cooled atoms held in a lattice of laser beams
Scientists say their clocks would have lost less than one second if they had running from the moment the universe was born with the Big Bang
They say the devices could help understand and predict earthquakes

A clock that is so accurate it will lose just one second in 16 billion years has been created by scientists.  The device, made using super-cooled atoms held within a lattice of laser beams, is around 1,000 times more precise than the atomic clocks currently used to define time.  Researchers say clocks with this level of accuracy could open up new areas of science by allowing tiny changes fluctuations in the strength of gravity to be measured.
