Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create ...

“Our system is remarkable because it’s incredibly simple,” said paper author and physicist David Grier of New York University ...

Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

Physicists at the University of Colorado Boulder have created the first time crystal that humans can actually see, using liquid crystals that swirl into never-ending patterns when illuminated by light ...

Crystals -- from sugar and table salt to snowflakes and diamonds -- don't always grow in a straightforward way. Researchers have now captured this journey from amorphous blob to orderly structures. In ...

In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions ...
