A review of emerging research suggests that field variations on the order of tens of millions of years may be linked to changes in heat flow across the core — mantle boundary. (nature.com)
In this study, we provide the first clear and simply measurable evidence for influence of geomagnetic field variations on mammal behavior. (frontiersinzoology.biomedcentral.com)
As seen in Figure 6, particularly the higher - frequency variations in the two radionuclide estimates agree rather well in phase and show higher amplitudes than the geomagnetic reconstructions, confirming the results by Snowball et al. (2007) that variations in radionuclide production rates on up to multi-centennial time scales are dominated by solar magnetic field variations. (swsc-journal.org)
