Washington, D.C.— The Geophysical Laboratory’s Christopher Glein has revealed the pH of water spewing from a geyser-like plume on Saturn’s moon Enceladus. His findings are an important step toward determining whether life could exist, or could have previously existed, on the sixth planet’s sixth-largest moon.

Washington, D.C., 28 April 2015—The high-resolution mass spectrometer “Panorama” built by Nu Instruments, Ltd. was installed in the Department of Earth, Planetary, and Space Sciences, UCLA in March.  The Geophysical Laboratory's Doug Rumble is a co-investigator of the project.

Washington, D.C., 22 April 2015— New work from the Geophysical Laboratory's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure.

Washington, D.C., 14 April 2015— The cores of terrestrial planets and satellite bodies, including the Moon, all contain large quantities of iron.  New work from the Geophysical Laboratory's Yingwei Fei provides new measurements of iron at lunar core conditions that will help build a direct compositional and velocity model of the Moon’s core in conjunction with limited lunar seismic data.

Washington, D.C., 20 March 2015— A team led by Geophysical Laboratory scientists was able to discover five new forms of silica under extreme pressures at room temperature.

Washington, D.C.—A team of scientists, including the Geophysical Laboratory's Zhenxian Liu, report experimental evidence for tetrahedrally coordinated carbon in high pressure carbonates. This bonding behavior could have significant implications for carbon reservoirs and fluxes, as well as for understanding the global geodynamic carbon cycle.

Washington. D.C.—The Geophysical Laboratory's Guoyin Shen and Zhisheng Zhao, have found that the hybrid Type II glass-like carbon possesses many advantageous properties, such as high strength, high volume compression, superelastic recovery from large volume deformation, and more. 

Washington, D.C., 2 March 2015—The Geophysical Laboratory's Robert Hazen has been awarded a $1.4 million grant from the W.M. Keck Foundation for a three-year data-driven research project on the co-evolution of the planet’s biology and geology.

Washington, D.C., 5 February 2015— A team of Geophysical Laboratory scientists have found “beautifully preserved” 15 million-year-old thin protein sheets in fossil shells from southern Maryland.

Washington, D.C., 28 January 2015— New findings from a team including Geophysical Laboratory's Ronald Cohen and Peng Zhang shows that a missing piece of the traditional theory explaining why metals become less conductive when they are heated was needed to complete the puzzle that explains Earth's field-generating process.

The AGU Fall Meeting 2014 will take place in San Francisco, CA from December 14-21.  Many staff members and postdoctoral associates from the Geophysical Laboratory will attend this year.  Check here daily for live updates on each day's science presentations.

Washington, D.C., 10 December 2014—New work from the Geophysical Laboratory's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen and reveals remarkable parallel between hydrogen and graphene under extreme pressures.

Washington, D.C., 17 November 2014— A team led by the Geophysical Laboratory's Timothy Strobel has synthesized an entirely new form of silicon, one that promises even greater future applications. Although silicon is incredibly common in today's technology, its so-called indirect band gap semiconducting properties prevent it from being considered for next-generation, high-efficiency applications. Strobel's silicon has a quasi-direct band gap that falls within the desired range for solar absorption, something that has never before been achieved.

Washington, D.C., 12 November 2014 —Data have suggested that deep, hot, fluid magma oceans of melted silicates, a major Earth material, may reside above the core-mantle boundary. The Geophysical Laboratory's Alex Goncharov has found, using high-pressure experiments with a proxy material, that the deep Earth materials conduct far less heat under increasing pressure than previously thought.

Washington, D.C., 27 October 2014—In a new paper in Nature Geoscience, the Geophysical Laboratory’s Sami Mikhail and Dimitri Sverjensky outline a compelling model for nitrogen accumulation in Earth’s atmosphere, suggesting subduction, and subsequent degassing at arc volcanoes, is key.
