Physicists have designed an electrical component that breaks time-reversal symmetry. Not quite the time machine from Hollywood but it should help with communication technology and quantum computing.
Scientists theorised, disproved, revamped and finally created a bizarre new form of matter in just five years.
Many scientists didn't believe that crystals made up of never-repeating patterns could exist. But they do and scientists are starting to understand the weird maths behind them.
When you see a repeating pattern, your mind easily imagines it continuing to infinity. There are mathematical rules behind the intriguing visuals.
