New evidence from deep mantle plumes suggests that Earth’s liquid outer core might be leaking tungsten isotopes into the lower mantle.
New research using a highly complete earthquake catalog shows that 72% of M4+ mainshocks are preceded by foreshocks, implying that foreshock activity is much more prevalent than previously thought.
Silicate melts containing H2O in the lowermost mantle are surprisingly dense and may stagnate there, trapping primordial volatiles and potentially causing some of the ultra-low velocity zones.
Scientists get one step closer to being able to predict jerks—notoriously capricious changes to Earth’s geomagnetic field detectable by satellites.
Earth’s magnetic field waxes and wanes as supercontinents form and break up, suggests a new study postulating a direct connection between our planet’s crust and its core.

Such disturbances probably do not occur on our own planet, but evidence for them might still exist elsewhere in the solar system.
A new study explores the possibility of cubic iron alloy structure at our planet's core.
How can researchers understand what happens at the center of the Earth when it can’t be measured directly?
