Further evidence of Earth's core leaking found on Baffin Island

A combined team of geochemists from Woods Hole Oceanographic Institution and California Institute of Technology has found evidence of high levels of helium-3 in rocks on Baffin Island—possible evidence that the Earth's core is leaking. In their paper published in the journal Nature, the group describes their study of helium-3 and helium-4 on the Canadian Arctic Archipelago.
