Earth's inner core is slowing down; could affect the planet's magnetic field, says new study

By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner core has experienced a bit of fluctuations in its movement over time. Amongst these, a major change was observed around 2009, which kind of negates earlier theories insinuating that the inner core consistently rotates faster than the Earth's surface
