For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A wave of recent experiments is now tearing at those boundaries, revealing ...

Imagine you're eating dinner. You try to pour some ranch dressing onto your plate to dip your veggies into. You tip the container upside down, but nothing comes out. Seems like a solid. So you shake ...

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

High school science misses a lot of the science researchers actually work with. For example, you learn that there are three states of matter—solid, liquid, and gas—but in advanced physics, things get ...

Superionic conductors (SICs) are materials intermediate between the crystalline and liquid states of matter, and their unusual behaviour has attracted fundamental interest for decades 1,2,3. Although ...
