Scientists observe a visible time crystal for the first time, revealing a phase of matter that repeats patterns through time.

For more than two decades, the International Space Station has provided a platform for growing and studying protein crystals. In the early days of microgravity research, scientists discovered that ...

MIT physicists have synthesized a new family of bulk crystals whose electrons behave as though they move in an effectively four-dimensional “superspace,” rather than being fully described by the three ...
