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.

New work by the Geophysical Laboratory's Kadek Hemawan and team has resulted in a method for synthesizing diamond at atmospheric pressure with a microwave capillary technique.

Last week, scientists from around the world were all about building a deeper understanding of the nature of biology, including modeling the origins of life on an abstract level starting from prebiotic conditions on Earth and, possibly, on other planets. The Geophysical Laboratory hosted Re-conceptualizing the Origin of Life, a week-long conference at our Washington, D.C. headquarters, exploring experimental, interdisciplinary and computational windows on the core concepts.

Using a variety of advanced techniques including x-ray diffraction, tomography, and molecular dynamics simulations, a team including the Geophysical Laboratory's Qiaoshi “Charles” Zeng, was able to create a model that describes both the observed short-range order in metallic glasses and encompasses long-range structural details.

Geophysical Laboratory alum Yoko Kebukawa was awarded the Geochemical Society of Japan Award for Young Researcher.  This award honors outstanding contributions to the advancement of geochemistry, cosmochemistry and environmental sciences. 

Using diamond-anvil cell technology combined with X-ray absorption spectroscopy, a research team led by the Geophysical Laboratory's Reinhard Boehler was able to demonstrate a melting temperature for iron of 3,090 K (about 5,100 degrees Fahrenheit) in the 100-gigapascal pressure range (about a million times normal atmospheric pressure).

Washington, D.C., 1 September 2015— As astronomers continue finding new rocky planets around distant stars, high-pressure physicists are considering what the interiors of those planets might be like and how their chemistry could differ from that found on Earth. New work from the Geophysical Laboratory's Sergey Lobanov, Nicholas Holtgrewe, and Alexander Goncharov demonstrates that different magnesium compounds could be abundant inside other planets as compared to Earth.

Washington, D.C., 26 August 2015—New research from a team led by the Geophysical Laboratory's Robert Hazen predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos.

Washington, D.C., 12 August 2015—Colossal magnetoresistance (CMR) is a property with practical applications in a wide array of electronic tools including magnetic sensors and magnetic RAM. New research from the Geophysical Laboratory's Maria Baldini, Dave Mao, Takaki Muramatsu, and Viktor Struzhkin successfully used high-pressure conditions to induce CMR for the first time in a pure sample of a compound called lanthanum manganite, LaMnO3.

Washington, D.C., 15 June 2015— New work from the Geophysical Laboratory's Stewart McWilliams and Alexander Goncharov used laboratory techniques to mimic stellar and planetary conditions, and observe how noble gases behave under these conditions, in order to better understand the atmospheric and internal chemistry of these celestial objects.
