The iron in Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid center of our planet that have, up until now, been difficult ...

Nearly 50 years ago, a process for core formation involving percolation of liquid iron through a solid, isotropic silicate matrix was proposed 1. This theory is well developed for the ideal case of a ...

Scientists recreated the intense pressures and temperatures found deep within the Earth, resulting in a discovery that complicates theories of how the planet and its core were formed. Stanford ...

Kevin Arrigo, a biological oceanographer at Stanford University, has spent nearly two decades studying remote sites in Antarctica that experts like to call an “oasis in a desert of ice.” They are so ...
