Pairing lasers with microwaves makes mind-bogglingly accurate electronic clocks – a potential boon for GPS, cell phones and radar

Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
