  • Kite’s Research on Valley Networks on Mars Published in Recent Article

    June 29, 2018

    Geophysical Sciences Assistant Professor Edwin Kite and two collegues have argued in a recent article in Science Advances that the branching geometry of valley networks on Mars is the result of water run-off, not groundwater flow. One important implication of this claim is that Mars possessed an active hydrological cycle in the past that included rain.

  • Foote’s Research on Evolution of Ancient Plankton Featured in PNAS

    June 07, 2018

    Geophysical Sciences Professor Michael Foote and his research colleagues have shown, in a recently published article of the Proceedings of the National Academy of Sciences, that there is a demonstrable relationship between instrinsic biotic interactions and extrinsic enviromnetal factors that drive changes in biodiversity. Foote and his colleagues have illuminated how changes in the axial tilt of the Earth influenced the course of evolution in ancient graptoloid plankton over the course of millions of years.

  • Shaw and Kite Receive AGU’s Outstanding Reviewers Award

    June 06, 2018

    Congratulations to Geophysical Sciences Associate Professor Tiffany Shaw and Assistant Professor Edwin Kite, who were recently recognized as among the American Geophysical Union's Outstanding Reviewers of 2017!

  • Boehnke, Davis, Stephan, and Trappitsch Challenge Classic Dating of Crust Formation

    June 06, 2018

    In a recently published article in the Proceedings of the National Academy of Sciences of the United States of America Geophysical Sciences postdoc Patrick Boehnke, Geophysical Sciences Professor Andrew Davis, Geophysical Sciences Research Prof. Thomas Stephan and former GeoSci postdoctoral scholar Reto Trappitsch reveal that they have discovered a way to analyze bits of the earliest continental crust found in tiny flecks of apatite using CHILI: GeoSci's one of a kind instrument that analyzes isotopic and chemical composition. Their discovery provides evidence that the Earth’s continental crust could have formed hundreds of millions of years earlier than previously thought, and life along with it.
