As a little challenge: first the danish press release: http://www.space.dtu.dk/Nyheder/Nyheder_paa_Space.aspx?guid={E29F2AB2-9EBD-407B-AD72-E401F5E0420C}
Here is the article: http://www.nature.com/ngeo/journal/v1/n6/abs/ngeo203.html >From the abstract: A large part of the Earth's magnetic field is generated by fluid motion in the molten outer core. [...] Here we show that changes in the magnetic field occurring over only a few months, indicative of fluid flow at the top of the core, can in fact be resolved. [...] We find that the core flow is spatially localized and involves rapid variations over a few months, with surprisingly large local accelerations. [...] The results mean that the DUT we measure in practice is not guaranteed to have no high frequency components, it merely happens to not have (had) them (in the past 50 years). This is particularly interesting, since the widely accepted theory that the earths magnetic field is spiralling towards a pole reversal, mean that the electrical/magnetical field will diverge from the axis of rotation from now on. Nobody has any idea what will happen in practice...
