Earth's Core Leaking? New Discovery Surprises Scientists

The study is based on discovery of traces of helium with concentration that has never been detected before.
There is a surprising new discovery about the Earth's core. An analysis of 62-million-old Arctic rocks has revealed that there is a slow trickle from the very heart of our plant. The analysis has been carried out by geochemists from the California Institute of Technology and Woods Hole Oceanographic Institution. According to Science Alert, the scientists found record concentrations of a helium isotopes inside the rocks they studied, which convinced them that this is the most compelling evidence of a slow leak in Earth's core.
A research detailing the discovery was published in Nature.
The scientists combined the results from an earlier analysis of ancient lava flow, which contained unusually high concentration of helium 3 to arrive at the conclusion. They believe there could be reserves of the elusive gas buried some 2,900km underground.
