Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth's core, where temperatures are so high that part of the iron is ...

Two new innovative methods describe how to measure the electrical resistivity of liquid iron -- such as that found in planetary cores -- at extremely high pressures and temperatures. Prior to this, ...

Iron is the most abundant element by mass on Earth. Despite being so common and well-studied, iron still manages to puzzle scientists by exhibiting electric and magnetic behaviors that are not fully ...
