New work from a Smithsonian-led team, including Carnegie’s Diana Roman, revealed what could be the most-important factor controlling the depth at which magma is stored under a volcano, upending long-held theories about the molten material’s upward journey through the Earth’s crust. Their findings—which could inform the creation of detailed models that more accurately forecast volcanic eruptions—are published in Science.

Recently, a team of scientists led by Carnegie’s Samuel Dunning and Timothy Strobel developed an original technique that predicts and guides the ordered creation of strong, yet flexible, diamond nanothreads, surmounting several existing challenges.  The innovation will make it easier for scientists to predict and synthesize the nanothreads—an important step toward applying the material to practical problems in the future. The work was recently published in the Journal of the American Chemical Society.

What’s Happening In The Depths Of Distant Worlds?

Silicate minerals make up most of the Earth’s mantle and are thought to be a major component of the interiors of other rocky planets. On Earth, the structural changes induced in silicates under high pressure and temperature conditions define key boundarie

The physics and chemistry that take place deep inside our planet are fundamental to the existence of life as we know it. But what forces are at work in the interiors of distant worlds, and how do these conditions affect their potential for habitability?

New work led by Carnegie’s Earth and Planets Laboratory uses lab-based mimicry to reveal a new crystal structure that has major implications for our understanding of the interiors of large, rocky exoplanets. Their findings are published by Proceedings of the National Academy of Sciences.
