Earth's core is 'leaking' gold, study finds

Earth's core is leaking precious metals like gold and ruthenium, according to a new study. Scientists found evidence of core-originating ruthenium in Hawaiian volcanic rocks, suggesting metals can migrate from Earth's center to the surface over billions of years. This discovery reveals that the core is less isolated than previously thought and provides insights into the formation of volcanic islands like Hawaii. The findings also indicate that some precious metals mined today may have originally come from Earth's core.
