Three billion years ago, long before the familiar machinery of plate tectonics had taken hold, Earth was already engaged in a profound act of self-renewal. Ancient rocks from Western Australia's Pilbara Craton have yielded chemical evidence that water was sinking deep into the planet's mantle through a process called 'dripduction'—dense, water-laden crust periodically collapsing inward, releasing moisture that fed volcanic fire and shaped the earliest continents. The discovery, led by geochemist Dr. Eric Vandenburg and a team spanning seven institutions across three continents, invites us to s
