	Scientists from Columbia University and the University of Illinois at Urbana-Champaign report that the Earth's core is spinning about one-quarter to one-half degree faster, per year, than the rest of the planet. The researchers analyzed 30 quakes occurring in the South Atlantic and measured at 58 seismic stations in Alaska. Differences were found in the travel times and shape of the waves, indicating differences in the core as the waves passed through the center of the Earth.

	That only makes sense. The Earth spin is gradually slowing down as it is "throwing" the moon further out. As the core is liquid it would tend to want to retain its spin speed and therefore be spinning faster.
