Putting the Squeeze on Nitrogen for High Energy Materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen. Hypothesized nitrogen polymers could form materials with higher energy content than any known non-nuclear material.

No Redoubt: Volcanic Eruption Forecasting Improved
Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns. New research from a team led by Carnegie’s Diana Roman retrospectively documented and analyzed the period immediately preceding the 2009 eruption of the Redoubt volcano in Alaska, which was characterized by an abnormally long period of pre-eruption seismic activity that’s normally associated with short-term warnings of eruption.

Carnegie’s Greg Asner Named Energy/Climate Fellow by U.S. State Department
Carnegie staff scientist Greg Asner has been selected as one of 22 experts to serve the U.S. government as part of the Energy and Climate Partnership of the Americas (ECPA) through the Senior ECPA Fellows Program. Fellows will work with local government agencies, civil society groups, and universities throughout the Western Hemisphere to discuss regional impacts of climate change and energy policy, and develop relationships for continued multi-lateral cooperation.

Breakthrough in Nanocrystals Growth
For the first time scientists, including researchers with the Geophysical Lab, 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. Researchers will now be able to develop ways to control conditions under which they are grown. The breakthrough will affect a wide range of applications including solar-cell technology and chemical and biological sensors.

Progreso excepcional en el mapeo de carbono
Mediante la integración de mapeo satélital, tecnología láser aerotransportada, y estudios a nivel de parcelas, los científicos de la Institución Carnegie Departamento de Ecología de Global, con colegas del Fondo Mundial para la Naturaleza WWF y en coordinación con el Ministerio Peruano del Ambiente (MINAM), han revelado los primeros mapas de alta resolución de carbono almacenado en la vegetación de bosques tropicales y emitido por prácticas de uso de la tierra. Estos nuevos mapas marcan el camino para el monitoreo preciso de el almacenamiento de carbono y emisiones en el marco de la propuesta de las Naciones Unidas para la Reducción de Emisiones por Deforestación y Degradación (REDD).

Revolution in Rain Forest Monitoring with MacArthur Grant
Tropical rain forests are treasure houses of biodiversity, but there has been no effective way to inventory and monitor their plant species over large areas. As a result, we have limited understanding of how climate change, clearing, invasive plants, and other threats are affecting these delicate ecosystems. A major advance in improving this situation is in the works, however. Gregory Asner of the Carnegie Institution’s Department of Global Ecology was just awarded a $1.8 million grant from the John D. and Catherine T. MacArthur Foundation to create a database of plant chemical and remote sensing signatures for tropical forest species.

Nailing down a crucial plant signaling system
Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell’s nucleus. Although many steps of the pathway were already known, new research from a team including Carnegie’s Ying Sun and Zhiyong Wang fills in a missing gap about the mechanism through which brassinosteroids cause plant genes to be expressed. Their research has implications for agricultural science and, potentially, evolutionary research.

New Possibilities for Hydrogen-Producing Algae
Photosynthesis produces the food that we eat and the oxygen that we breathe ― could it also help satisfy our future energy needs by producing clean-burning hydrogen? Researchers studying a hydrogen-producing, single-celled green alga, Chlamydomonas reinhardtii, have unmasked a previously unknown fermentation pathway that may open up possibilities for increasing hydrogen production.

Mercury Not Like Other Planets MESSENGER Finds
The MESSENGER spacecraft has shown scientists that Mercury doesn’t conform to theory. Its surface material composition differs from both those of the other terrestrial planets and expectations prior to the MESSENGER mission, calling into question current theories for Mercury’s formation. Its magnetic field is unlike any other in the Solar System, and there are huge expanses of volcanic plains surrounding the north polar region of the planet and cover more than 6% of Mercury’s surface.

New clues to the early Solar System from ancient meteorites
In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from a team including Carnegie scientists focuses on one particularly old type of meteorite called diogenites. These samples were examined using an array of techniques, including precise analysis of certain elements for important clues to some of the Solar System's earliest chemical processing.

Revolutionary nanotechnology illuminates brain cells at work
Until now it has been impossible to accurately measure the levels of important chemicals in living brain cells in real time and at the level of a single cell. Scientists at the Carnegie Institution’s Department of Plant Biology and Stanford University are the first to overcome this obstacle by successfully applying genetic nanotechnology using molecular sensors to view changes in brain chemical levels...
