Washington, D.C., 23 June 2016 — New work published in Physical Review Letters by the Geophysical Laboratory’s Alexander Goncharov and University of Edinburgh’s Stewart McWilliams measures the conditions under which hydrogen undergoes this transition in the lab and finds an intermediate state between gas and metal, which they’re calling “dark hydrogen.”

Washington, D.C., 8 June 2016— Using laboratory techniques to mimic the conditions found deep inside the Earth, a team of Geophysical Laboratory scientists led by Ho-Kwang “Dave” Mao has identified a form of iron oxide that they believe could explain seismic and geothermal signatures in the deep mantle.

Washington, D.C., 1 June 2016— Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here. The motion of liquid iron in the planet’s outer core, a phenomenon called a “geodynamo,” generates the field. But how it was first created and then sustained throughout Earth’s history has remained a mystery to scientists. New work published in Nature from a team led by the Geophysical Laboratory's Alexander Goncharov sheds light on the history of this incredibly important geologic occurrence.

Nagoya, Japan, 11 May 2016—Ronald Cohen was an invited speaker at the AMTC5 workshop in Nagoya May 11-13, 2016 and spoke on "Strong Coupling Ferroelectrics, How They Work and How They Can Be Improved."  He then visited ELSI (Earth and Life Sciences Institute) at Tokyo Tech and spoke on “First-principles studies of the deep Earth.”

Washington, D.C., 28 April 2016—New work from a research team led by the Geophysical Laboratory's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field. Their results could shed light on Earth’s early days when the core was formed through a process called differentiation.

Washington, D.C. 29 March 2016—The Deep Carbon Observatory Executive Committee met on 1-2 March 2016 to discuss overarching themes for DCO’s final years, as well as plans beyond the end of the decadal program in 2019. The meeting was held at the headquarters of the Carnegie Institution for Science in Washington, D.C. and included a strategic discussion with Carnegie president Matthew Scott.

Washington, D.C., 18 March 2016—Geophysical Laboratory team Tim Strobel, Venkat Bhadram, and alum DuckYoung Kim, has discovered a new transition metal titanium pernitride, TiN2, which is ultraincompressible and could be a potential superhard material.

Hokkaido, Japan, 19 February, 2016—More than 60 scientists from around the world, including many from Carnegie, gathered at the perpetually snowing Rusutsu Ski Resort for the first Solar System Symposium held in western Hokkaido, Japan from Februrary 17-19, 2016. 

Washington, D.C., 16 February 2016— The Geophysical Laboratory’s Dina Bower and Andrew Steele weigh in on whether microstructures found in 3.46 billion-year-old samples of a silica-rich rock called chert found in Western Australia are the planet’s oldest fossils. The purported fossils have been a heated scientific controversy for many years. The team asserts that at least a portion of the microstructures are actually pseudo-fossils.

Washington, D.C., 8 February 2016—A team including the Geophysical Laboratory's Qiaoshi “Charles” Zeng and Ho-kwang “Dave” Mao, among others, is trying to figure out the rules that govern metallic glass’s creation. They are doing this by looking at metallic glasses under extreme pressures. High-pressure research can be used to probe structure on an atomic level and understand a material’s state of order or disorder.

EFree, a research center at the Geophysical Laboratory, held a Center-wide Neutron Day on December 10, 2015 at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee.

The Geophysical Laboratory’s own Bob Hazen will be starring in “Life’s a Rocky Start,” a PBS NOVA special on January 13, 2016 at 9pm EST on PBS.

The AGU Fall Meeting 2015 will take place in San Francisco, CA from December 13-18.  Many staff scientists and postdoctoral associates from the Geophysical Laboratory will attend this year.  Check here daily for live updates on each day's science presentations.

The Geophysical Laboratory's Tim Strobel is highlighted in the November issue of New Scientist.  He talks about hacking silicon's structure to make it more efficient for use in computer chips and solar panels, while explaining his new silicon allotrope, Si24.

The Geophysical Laboratory's Anat Shahar and Bob Hazen were announced as the recipients of the Mineralogical Society of America's (MSA) 2016 MSA Award and Roebling Medal, respectively.  They will receive their awards at the MSA meeting in Denver in September 2016.
