The researchers found instead that significant changes were cyclical and corresponded to the relative positions of the earth and the sun.
However, a new report on a separate isotope has again correlated radioisotope decay acceleration with nearness to the sun.
Since that time, investigators have yet to discover a satisfying physical mechanism explaining how the sun might accelerate the decay of radioactive atomic nuclei.
For example, although at the time of the Brookhaven and Stanford reports solar neutrinos were implicated, it appears that neutrinos are just too small and too few.
For example, RATE found a high accumulation of helium, a product of radioisotope decay, still trapped inside small crystals.
If evolutionary ages are accurate, the helium should have leaked into the atmosphere millions of years ago.
