Does an anomaly in the Earth’s magnetic field portend a coming pole reversal?
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
How we discovered that the Earth’s inner core is older than previously thought
The Earth's inner core is more than half a billion years older than previously thought, shows a study. The results could help us better understand the processes that shape the planet's surface.
Newly discovered layer in Earth’s mantle can affect surface dwellers too
The discovery of a thickly viscous layer which traps sinking plates below Earth's surface has wide implications, not least as a cause of earthquakes.
Our view of Earth’s inner core is flipped on its side
The planet Earth’s inner core is not a single solid mass but comprised of two layers, and new evidence about the core’s composition from a team of US and Chinese geophysicists suggests that the innermost…
X-rays force a rethink on how Earth’s core formed
Our planet’s interior is complex and has many layers. Their formation and structure contain many unsolved mysteries. But new research is providing some clues about how Earth’s internal structure may have…
