Major scientific breakthroughs in 2025 have reshaped our understanding of Earth's mysterious core. One of the most intriguing findings suggests that precious metals, including gold, are slowly migrating from the planet's core towards the surface. This phenomenon, discovered through isotopic analysis of ruthenium in volcanic rocks from Hawaii, challenges the long-held belief that the core is entirely sealed off from the rest of the Earth. Scientists now believe that superheated mantle plumes act as conduits, carrying these elements upward over millions of years, eventually reaching the crust through volcanic activity. Further discoveries revealed the Earth's inner core is not a conventional solid but exists in a 'superionic state,' where light elements like carbon flow freely through a stable iron lattice, making it surprisingly pliable. This explains decades-old seismic anomalies that baffled researchers. Additionally, studies indicated that the inner core's shape is changing and it may not be uniformly solid, with shifts observed over the past two decades. Researchers also highlighted carbon's pivotal role in the inner core's ancient solidification. Adding to these revelations, new evidence emerged proposing that the inner core might actually consist of two distinct layers, further complicating and enriching our models of Earth's internal structure. These collective findings from 2025 represent significant advances in geology and planetary science.
