Scientists have used the same technology that brought us time crystals to create a room-temperature maser - a microwave laser - that overcomes many of masers' past problems.

You probably scratched your head last year if you read about time crystals, likely 2017's most esoteric, widely covered popular science story. Even if you understood how they worked, you might not have known what use they could have. Time crystals, systems of atoms that maintain a periodic ticking behaviour in the presence of an added electromagnetic pulse, have now piqued the interest of one well-funded government agency: The US Department of Defence.
My first question was, "What is a time crystal?" Harvard graduate students Soonwon Choi, Joonhee Choi and postdoctoral researcher Renate Landig all started laughing. "That's a very good question," said Soonwon. The time crystal's silly science fiction name shrouds its deep quantum mechanical nuance. Sometimes a name is simply the easiest approximation to describe something far more complex than inquiring minds can conjure.
