Atomic Clocks With Unprecedented Accuracy

 A team of physicists from the United States and Russia announced that it has developed a means for computing, with unprecedented accuracy, a tiny, temperature-dependent source of error in atomic clocks. Although small, the correction could represent a big step towards atomic timekeepers' longstanding goal of a clock with a precision equivalent to one second of error every 32 billion years -- longer than the age of the universe.
