New findings about the Earth's core

Under extreme pressures and temperatures, one of the main metals of the Earth's interior has exhibited a never-before-seen transition.

Iron oxide was subjected to conditions similar to those at the depth where the Earth's innermost two layers meet.

At 1,650C and 690,000 times sea-level pressure, the metal changed the degree to which it conducted electricity.

But, as the team outlined in Physical Review Letters, the metal's structure was surprisingly unchanged.
