Liquid crystals are substances that flow like a liquid but maintain some of the ordered structure of crystals. Liquid-crystal molecules tend to be elongated and to orient in specific directions.

In 1984, scientists made a crystalline alloy that had a seemingly impossible arrangement of atoms. They had discovered the first quasicrystal — a type of material that transformed ideas about ...

To store energy with a time crystal, make it a double. A mathematical analysis shows that putting two time crystals into a coordinated state could create a quantum battery-like device. Time ...
