· It’s true—some rocks can float on water for years at a time. And now scientists know how they do it, and what causes them to eventually sink. X-ray studies at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have helped scientists to solve this mystery by scanning inside samples of lightweight, glassy, and
