Earth's Core Leak: Troubling Discovery Raises Concerns

Researchers have discovered that ancient lava flows from Baffin Island in Canada's Arctic Archipelago contain high levels of helium-3, helium-4, and another rare isotope, suggesting a possible leak from the Earth's core. While the implications for the core are unclear, the leak does not pose any immediate danger as the remote location of the lava flows minimizes the risk of exposure.
