Jonathan Tucker defended his Ph.D. on "A Portrait of Terrestrial Volatile Evolution from Mantle Noble Gases." He will go to the Department of Terrestrial Magnetism on a Carnegie Postdoctoral Fellowship.

Our new paper is out today in Science: Preservation of Earth-forming events in the tungsten isotopic composition of modern flood basalts by Hanika Rizo et al. W anomalies in the mantle demonstrate that the Earth has not erased signatures from the main stage of planet formation. Also see the Perspective by Tais Dahl.

Enjoy!
