‘Earth’s core may be leaking a rare and valuable element’

Scientists have discovered that Earth’s core may be leaking helium-3, a rare and valuable element. The high levels of helium-3 and neon-22 found in volcanic rocks on Baffin Island suggest that these rocks came from the core itself. It is believed that helium-3 and neon-22 have been leaking from the core for millions or billions of years, but at a very slow rate. While the leakage does not have any negative impact on the planet, it could have positive implications for nuclear fusion.
