Geochemists from Woods Hole Oceanographic Institution and California Institute of Technology discovered high levels of helium-3 in rocks on Baffin Island, suggesting a potential leak from Earth's core. Helium-3 is an ancient isotope, prevalent during Earth's formation, typically trapped in the core. Its presence on the surface, with high helium-3 to helium-4 ratios, suggests core leakage. Such findings could provide a unique opportunity to study the core's material, offering insights into Earth's inner workings. Research still needs to be conducted on any form of commercialisation.
