Washington, DC— New work from Carnegie’s Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.
Washington, DC—Carnegie’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.
Anat Shahar was awarded the Clarke Award of the Geochemical Society. It is awarded to an early-career scientist for " a single outstanding contribution to geochemistry or cosmochemistry, published either as a single paper or a series of papers on a single topic. "
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.

Washington, DC, December 16, 2014—New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures.
Recent advances in our understanding of the quantities, movements, forms and origin of carbon in Earth are summarized in a just-published report. The research represents fast-paced progress on the depths of the biosphere, Earth, what erupts from volcanoes and leaks from sea floors, what descends back into Earth’s great depths, and the nature of carbon-bearing materials within planets.
Washington, DC—Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology.
The Geophysical Laboratory's Andrew Steele joins the Rosetta team as a Co-Investigator working on the COSAC instrument aboard the Philae lander (Fred Goesmann Max Planck Institute - PI). On 12 November 2014 the Philae system will be deployed to land on the comet and begin operations.
Washington, DC— A team including Carnegie’s Malcolm Guthrie and George Cody has, for the first time, discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymer fibers.
Washington, DC — A team of scientists led by Carnegie’s Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond.
Torredu, India---Geophysical Laboratory research scientist Maddury Somayazulu visited Torredu, India this month and gave a talk to the children of the village in telugu (a South-Central Dravidian language) about how science impacts society.
The high water storage capacity of minerals in Earth’s mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle.
Sendai, Japan—The Geophysical Laboratory's webmaster and departmental assistant, Michelle Scholtes, was invited to the Advanced Institute for Materials Research at Tohoko University in Sendai, Japan for a foreign exchange of information regarding administrative support in a scientific research institution. The visit included the exchange of opinions and experiences regarding research support systems at each institute.
Washington, DC—The Department of Energy (DOE) has awarded Carnegie $10 million over four years for basic research that could lead to the discovery of new energy materials through its program to support Energy Frontier Research Centers.
Washington, DC—Breaking research news from a team of scientists led by Carnegie’s Ho-kwang “Dave” Mao reveals that the composition of the Earth’s lower mantle may be significantly different than previously thought. These results are to be published by Science.
The Geophsyical Laboratory presented various topics at the third annual USA Science & Engineering Festival, the largest science, technology, engineering and math (STEM) education event of its kind in the United States!

“Perhaps no building being erected at the present time has excited so much interest ... as has the new edifice in progress [at Broad Branch Road]. Certainly no structure has required so much precise care in workmanship and a thorough knowledge of building to meet the delicate needs of a building of this character. It is the last word in scientific building.”
Washington, DC—New research shows that a remarkable defect in synthetic diamond produced by chemical vapor deposition allows researchers to measure, witness, and potentially manipulate electrons in a manner that could lead to new “quantum technology” for information processing.
Washington, DC—Table salt, sodium chloride, is one of the first chemical compounds that schoolchildren learn. Standard chemistry textbooks say that sodium and chlorine have very different electronegativities and thus must form an ionic compound with a well-defined composition.
A research team from the Geophysical Laboratory, including Oleksandr Kurakevych, Timothy Strobel, Duck Young Kim and George Cody, has reported the synthesis of an ionic semiconductor, Mg2C, under high-pressure, high-temperature conditions, which is fully recoverable to ambient conditions.
The Story of Earth: The First 4.5 Billion Years, From Stardust to Living Planet, written by the Geophysical Laboratory's Bob Hazen, has been chosen from books released in 2012 as one of the five titles on the short list for the current Phi Beta Kappa Award in Science, one of the three book awards given by Phi Beta Kappa annually.
Washington, DC— Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole cosmos.
