Where on Earth Did the Moon’s Water Come From?
Water is perhaps the most important molecule in our solar system. Figuring out where it came from and how it was distributed within and among the planets can help scientists understand how planets formed and evolved. New research from a team including Carnegie’s Erik Hauri demonstrates that water from the interiors of the Earth and Moon has a common origin.

Earth’s getting “soft” in the middle
A new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly, suggesting that the material there is softer than previously thought.

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria  by mid-century if emissions are not dramatically curtailed now.

New web resource to improve crop engineering
The Carnegie Institution’s Department of Plant Biology today announced the launch of a new web-based resource that promises to help researchers around the world meet increasing demands for food production, animal feed, biofuels, industrial materials, and new medicines. It is the Plant Metabolic Network (PMN) at http://www.plantcyc.org/

Carnegie wishes laser inventor happy 99th birthday
Nobel laureate and trustee emeritus Charles Townes is celebrating his 99th birthday on Monday, July 28. Townes joined the Carnegie board in 1965, one year after he shared the Nobel Prize in Physics with Alexander Prokhorov and Nikolai Basov for the development of the maser, acronym for microwave amplification by stimulated emission of radiation, and its better-known optical counterpart, the laser.

Exploring Planets in Distant Space and Deep Interiors
In recent years researchers have found hundreds of new planets beyond our solar system, raising questions about the origins and properties of these exotic worlds—not to mention the possible presence of life. Speaking at a symposium titled “The Origin and Evolution of Planets” held at the annual meeting of the American Association for the Advancement of Science, two Carnegie Institution scientists presented their perspectives on the new era of planetary exploration.

Controlling a sea of information
Curators at one of the world’s most widely used biological databases, The Arabidopsis Information Resource, or TAIR, have joined forces with the journal Plant Physiology, to solve the “flood of information” dilemma.

Mountaintop Blasting to Mine the Sky with the Giant Magellan Telescope
Astronomers began to blast 3 million cubic feet of rock from a mountaintop in the Chilean Andes today to prepare for the world’s largest telescope at the Carnegie Institution’s Las Campanas Observatory. Over the next few months, more than 70 controlled blasts will break up the rock while leaving a solid bedrock foundation for the telescope and its precision scientific instruments.More information about the telescope is here

Preventing Climate Change: The Size of the Energy Challenge
In 2004 a very popular study aimed to address climate change by deploying wedges of different existing energy technologies or approaches. According to the study by Robert Socolow and Stephen Pacala, each wedge would avoid one billion tons of carbon (1 GtC) emissions per year after 50 years. The study showed that, at that time, seven wedges could stabilize carbon dioxide emissions relative to what would happen if things remained “business-as-usual.” A new perspective paper from a group including Carnegie’s Ken Caldeira uses the wedge approach to estimate the size of the energy challenge posed by climate change today.

Carnegie’s Rubén Rellán-Álvarez Receives Young Scientist Award
Postdoctoral fellow Rubén Rellán-Álvarez, at the Department of Plant Biology, has been awarded the prestigious Marschner Young Scientist Award by the International Plant Nutrition Colloquium. The award was established for “outstanding Ph.D. students and early-career researchers with the potential to become future research leaders.”

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.

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.

Communicating with the world across the border
All living cells are held together by membranes, which provide a barrier to the transport of nutrients. They are also the communication platform connecting the outside world to the cell’s interior control centers. Thousands of proteins reside in these cell membranes and control the flow of select chemicals, which move across the barrier and mediate the flux of nutrients and information. Little was known about the relationships among membrane proteins and interior proteins. A team of scientists has revealed how membrane proteins were networked with each other and with the signaling proteins inside the cell.

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.

Plant toughness: Key to cracking biofuels?
Along with photosynthesis, the plant cell wall is one of the features that most set plants apart from animals. A structural molecule called cellulose is necessary for the manufacture of these walls. Cellulose is synthesized in a semi-crystalline state that is essential for its function in the cell wall function, but the mechanisms controlling its crystallinity are poorly understood. New research from a team including current and former Carnegie scientists reveals key information about this process, as well as a means to reduce cellulose crystallinity, which is a key stumbling block in biofuels development.

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).
