From http://www.theage.com.au/national/education/science-of-earths-core-takes-a-dramatic-twist-20150301-13oz5m.html we have this report:

For the first time, employing a sophisticated earthquake-deciphering technique (thus far only used to illuminate the planet's upper shells), a team of scientists from Illinois University in the US and Nanjing University in China have succeeded in exploring the inner core itself.

Their ground-breaking research supports an earlier prediction that deep within the inner core sits yet another even deeper innermost shell, containing iron crystals aligned in a different direction (north-south rather than east-west for the rest of the core).
