'Gyroscope' molecules form crystal that's both solid and full of motion

To make a solid crystal, molecules are generally so tightly packed together there’s no room for any movement. It means that solid crystals – despite their strength and durability – have generally been ignored as having any possible function as molecular machines. Researchers have now formed a crystal out of molecules that look like gyroscopes. The crystal is externally solid but contains moving parts.
