Washington, DC—Carnegie’s Yingwei Fei and Lin Wang were part of an international research team that synthesized a new ultrahard form of carbon glass with a wealth of potential practical applications for devices and electronics. It is the hardest known glass with the highest thermal conductivity among all glass materials. Their findings are published in Nature.

Function follows form when it comes to understanding the properties of a material. How its atoms are chemically bonded to each other, and their resulting structural arrangement, determines a material’s physical qualities—both those that are observable by the naked eye and those that are only revealed

Called MagNIFIES, for Magellans' Near-Infrared Five-band Immersion grating Efficient Spectrograph, the completed instrument will have the largest simultaneous spectral coverage of any high-resolution spectrograph in the world. It was the brainchild of

Washington, DC—The first-ever silicate mineral recovered from the Earth’s lower mantle has been named after retired Carnegie scientist Ho-kwang “Dave” Mao, an experimental geophysicist whose work redefined our understanding of how materials behave under the extreme pressure and temperature conditions found inside Earth and other planets.

A team led by the University of Nevada Las Vegas’ Oliver Tschauner reported the discovery in Science this week and Carnegie’s Yingwei Fei wrote an accompanying essay in the same issue, contextualizing the importance of the work and the significance of the chosen name—davemaoite.

Carnegie's Paul Butler has been leading work on a multiyear project to carry out the first reconnaissance of all 2,000 nearby Sun-like stars within 150 light-years of the solar system (1 lightyear is about 9.4 trillion kilometers). His team is currently monitoring about 1,700 stars, including 1,000 Northern Hemisphere stars with the Keck telescope in Hawaii and the UCO Lick Observatory telescope in California, and 300 Southern Hemisphere stars with the Anglo-Australian telescope in New South Wales, Australia. The remaining Southern Hemisphere stars are being surveyed with Carnegie's new Magellan telescopes in Chile. By 2010 the researchers hope to have completed their planetary

High-elevation, low relief surfaces are common on continents. These intercontinental plateaus influence river networks, climate, and the migration of plants and animals. How these plateaus form is not clear. Researchers are studying the geodynamic processes responsible for surface uplift in the Hangay in central Mongolia to better understand the origin of high topography in continental interiors.

This work focuses on characterizing the physical properties and structure of the lithosphere and sublithospheric mantle, and the timing, rate, and pattern of surface uplift in the Hangay. They are carrying out studies in geomorphology, geochronology, thermochronology, paleoaltimetry,

The Anglo-Australian Planet Search (AAPS) is a long-term program being carried out on the 3.9-meter Anglo-Australian Telescope (AAT) to search for giant planets around more than 240 nearby Sun-like stars. The team, including Carnegie scientists,  uses the "Doppler wobble" technique to search for these otherwise invisible extra-solar planets, and achieve the highest long-term precision demonstrated by any Southern Hemisphere planet search.

The WGESP was charged with acting as a focal point for research on extrasolar planets and organizing IAU activities in the field, including reviewing techniques and maintaining a list of identified planets. The WGESP developed a Working List of extrasolar planet candidates, subject to revision. In most cases, the orbital inclination of these objects is not yet determined, which is why most should still be considered candidate planets. The WGESP ended its six years of existence in August 2006, with the decision of the IAU to create a new commission dedicated to extrasolar planets as a part of Division III of the IAU. The founding president of Commission 53 is Michael Mayor, in honor of

Hélène Le Mével studies volcanoes. Her research focuses on understanding the surface signals that ground deformations make to infer the ongoing process of the moving magma  in the underlying reservoir. Toward this end she uses space and field-based geodesy--the mathematics of the area and shape of the Earth--to identify, model and interpret this ground deformation.

She uses data from radar called Interferometric Synthetic Aperture Radar (InSAR), and data from the Global Positioning System (GPS) to characterize ground motion during volcanic unrest. She also collects gravity data, which indicate changes in mass and/or density underground. These data sets,

Roiling cauldrons of liquid-laden material flow within Earth’s rocky interior. Understanding how this matter moves and changes is essential to deciphering Earth’s formation and evolution as well as the processes that create seismic activity, such as earthquakes and volcanoes. Bjørn Mysen probes this hidden environment in the laboratory and, based on his results, models can help explain what goes on in this remote realm.

Mysen investigates changes in the atomic properties of molten silicates at high pressures and temperatures that pervade the interior Earth. Silicates comprise most of the Earth's crust and mantle. He uses devices, such as the diamond anvil

Peter van Keken studies the thermal and chemical evolution of the Earth. In particularly he looks at the causes and consequences of plate tectonics; element modeling of mantle convection,  and the dynamics of subduction zones--locations where one tectonic plate slides under another. He also studies mantle plumes; the integration of geodynamics with seismology; geochemistry and mineral physics. He uses parallel computing and scientific visualization in this work.

He received his BS and Ph D from the University of Utrecht in The Netherlands. Prior to joining Carnegie he was on the faculty of the University of Michigan.

Cosmochemist Larry Nittler studies extraterrestrial materials, including meteorites and interplanetary dust particles (IDPs), to understand the formation of the Solar System, the galaxy, and the universe and to identify the materials involved. He is particularly interested in developing new techniques to analyze different variants of the same atom—isotopes—in small samples. In related studies, he uses space-based X-ray and gamma-ray instrumentation to determine the composition of planetary surfaces. He was part of the 2000-2001 scientific team to hunt for meteorites in Antarctica.

Nittler is especially interested in presolar grains contained in meteorites and in what
