  • Dauphas on new iron fractionation paper

    February 20, 2017

    Louis Block Professor Nicolas Dauphas was a coauthor on a new paper in Nature Geosciences on Earth's iron fractionation. Earth has a significantly elevated level of Iron-56 relative to the chrondritic meteorites it was presuably built from. One theory was that this was due to fractionation during core-mantle segregation. Nicolas was part of a team that showed experimentally that the conditions relevant for core-mantle separation do not cause the observed fractionation, so there must be some other explanation for it.

  • Krijt wins Hubble Fellowship

    February 14, 2017

    Postdoctoral scholar Sebastiaan Krijt has won a prestigious three-year Hubble Fellowship, which are awarded to only 5% of applicants. Sebastiaan will work with associate professor Fred Ciesla and collaborators to explore the fate of carbon-bearing molecules during the earliest stages of planet formation.  Congratulations, Sebastiaan!

  • Professor Moyer on Climate Change and Global Security Panel

    February 08, 2017

    Associate Professor Liz Moyer is on a panel sponsered by the Chicago Council of Global Affairs about Climate Change and Global Security tonight, Feb. 9th. Representing the University in public forums like this is an important role of the faculty in society which Professor Moyer is particularly active in.

  • Dauphas explains Earth-Moon isotopic similarity

    January 26, 2017

    Louis Block Professor Nicolas Dauphas has published a new paper in Nature in which he shows that Earth formed from material similar to enstatite meteorites. This implies isotopic stratification in the early Solar System so that the giant impactor that formed the Moon probably had a similar isotopic composition to Earth. The isotopic similarity of Earth and the Moon had been a major mystery since calculations suggest that most of the material that forms the Moon should come from the giant impactor and before Nicolas' work there was no reason to assume that the impactor should be isotopically similar to Earth.
