A meditation teacher of mine once said, "You know, the mind can be very weird," and as it turns out, so can matter. Big in science news last week was the story, as reported for Nature and Scientific American by Elizabeth Gibney, that a new form of matter has been created. So-called "time crystals" aren't a video game power up or a sci-fi plot device – they're a bizarre state of matter which shows a crystal structure not in space, but over time. The newly created time crystals are a development of an idea from 2012, and are slightly less improbable than the original concept. However, as researcher Norman Yao, who is an author on both of the papers reported on, said, "It's less weird than the first idea, but it's still fricking weird."
