Recently i found out this uber strange article about nuclear decay rates being somehow showing seasonal variations with a high correlation with sun activity. Two very precise questions:
1) has this been experimentally confirmed/disproved? an experiment using neutrinos from a fission reactor would be awesome, although probably a couple orders of magnitude below the required luminosity (at least to be comparable with solar sources)
2) could the standard model possibly allow neutrinos to modulate decay rates in this way? or do we need new physics?

EDIT brief explanation why i tag this question as
cavity-qed; because it is the only other known mechanism we are aware that you can use to shift decay rates of energy levels, it might be interesting to see if there are deeper relationships between both mechanisms involved
EDIT 27/01/2013 Another paper about this, but now the SuperKamiokande data is compared with data from Brookhaven: http://arxiv.org/abs/1301.3754 They also propose a model of the effect called neutrino "resonant spin-flavor precesion", and i'll be damned if i knew what that is.
