Scientists have just made a surprising new discovery: The Earth's inner core is not only changing its rotation speed, but may also be deforming.

Heat from planet formation, radioactive decay of some elements, and friction between layers keep the Earth's core at extremely high temperatures after 4.5 billion years.

Scientists are working on a new project that promises to create a record melting material. It can survive even being thrown into the heart of the Earth, where temperatures reach
