Washington, DC—Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices.
Washington, DC—Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex—structural materials containing protein and polysaccharide—are present in abundance in fossils of arthropods from the Paleozoic era.
Washington, DC, 1 January 2011-This is an image of organic carbon in a ordinary chondritic meteorite obtained using a scanning transmission X-ray microscope at the Advanced Light Source, Lawrence Berkeley Laboratory.
Washington, DC—A group at the Geophysical Laboratory (GL) and the Department of Terrestrial Magnetism (DTM), who share the Broad Branch Road (BBR) campus in Washington, have been recognized by So Others Might Eat (SOME) for serving the “hungry and homeless of Washington for over 20 years.”
Washington, DC—Carnegie biogeochemist Marilyn Fogel, developmental biologist Marnie Halpern, and astronomer Stella Kafka were selected from over 500 applicants to be USA Science & Engineering Festival “Nifty Fifty” lecturers.
Argonne, ILL—For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size.
Washington, DC, 18 August 2010- Researchers from the University of Michigan and the Geophysical Laboratory have demonstrated a new method for quantitatively measuring the degree of pressure-induced atomic disordering in pyrochlore oxides using synchrotron x-ray diffraction, synchrotron infrared spectroscopy and Raman scattering techniques.
Washington, DC— Up to now scientists thought that the trace amounts of carbon on the surface of the Moon came from the solar wind. Now researchers at the Carnegie Institution’s Geophysical Laboratory have detected and dated Moon carbon in the form of graphite—the sooty stuff of pencil lead—which survived from the late heavy bombardment era 3.8 billion years ago.
Washington, DC — The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans.
Washington, DC—An unprecedented study of bald eagle diet, from about 20,000 to 30,000 years ago to the present, will provide wildlife managers with unique information for reintroducing Bald Eagles to the Channel Islands off California.
Washington, DC, 15 April 2010- Single-crystal relaxor ferroelectrics are useful and fascinating systems, but understanding the inner workings of these complex materials has been very challenging. They have spatial and temporal heterogeneities over a range of length and time scales.
Metallic glasses are emerging as potentially useful materials at the frontier of materials science research. They combine the advantages and avoid many of the problems of normal metals and glasses, two classes of materials with a very wide range of applications.
Washington, DC— Carnegie scientists Kenneth Caldeira of the Department of Global Ecology, Yingwei Fei of the Geophysical Laboratory, and Steven Shirey of the Department of Terrestrial Magnetism have been elected 2010 Fellows of the American Geophysical Union (AGU).
Washington, DC—Physicists have long wondered whether hydrogen, the most abundant element in the universe, could be transformed into a metal and possibly even a superconductor—the elusive state in which electrons can flow without resistance.
Single-crystal diamonds produced at the Geophysical Laboratory are traveling with a major museum exhibit called the Nature of Diamonds. The display focuses on the beauty of diamonds, their geological origins, and the science of diamond.
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution.
Washington, DC— The Alfred P. Sloan Foundation has awarded the Carnegie Institution a $4 million grant over three years to initiate the Deep Carbon Observatory -- an international, decade-long project to investigate the nature of carbon in Earth's deep interior.
Argonne, IL—Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the “giant magnetoresistance effect,” which made it possible to pack more data onto smaller and smaller hard drives.
Washington, DC— Robert Hazen, senior staff scientist at the Carnegie Institution’s Geophysical Laboratory, will receive the 2009 Distinguished Public Service Medal of the Mineralogical Society of America.
