Born to one of the original Trekkies (her mother) DTM Postdoctoral Fellow Erika Nesvold grew up a self-proclaimed science fiction nerd, a hobby that soon evolved into her passion for astronomy. Today she ventures into the stars her fellow Star Trek fans dreamed of one-day exploring for themselves by studying the effects exoplanets have on their debris disks.


Deep Mantle Chemistry Surprise: Carbon Content Not Uniform

Marion le Voyer

Even though carbon is one of the most abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth’s interior. Analysis by Carnegie’s Marion Le Voyer and Erik Hauri of crystals containing completely enclosed mantle magma with its original carbon content preserved has doubled the world’s known finds of mantle carbon. The findings are published in Nature Communications.
