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.

Scientists Find Moon Whiskers
Up to now scientists thought that the trace carbon on the surface of the Moon came from the solar wind. Now researchers at the Geophysical Lab have detected and dated Moon carbon in the form of graphite, which survived from the late heavy bombardment era 3.8 billion years ago. The discovery means that the Moon could hold a record of the meteoritic carbon input to the Earth-Moon system, when life was just beginning to emerge. Multimedia version

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.

Joe Berry Elected Fellow of the American Geophysical Union
Joseph A. Berry, of the Department of Global Ecology, has been elected a 2009 Fellow of the American Geophysical Union (AGU). He is one of 54 2009 Fellows—only 0.1% of the members are elected annually.

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.

Acidifying Oceans Add Urgency to CO2 Cuts
Stanford, CA— It’s not just about climate change anymore. Besides loading the atmosphere with heat-trapping greenhouse gases, human emissions of carbon dioxide have also begun to alter the chemistry of the ocean—often called the cradle of life on Earth. The ecological and economic consequences are difficult to predict but possibly calamitous, warn a team of chemical oceanographers in the July 4 issue of Science, and halting the changes already underway will likely require even steeper cuts in carbon emissions than those currently proposed to curb climate change.

New Cancer Diagnostic Technique Debuts
Cancer cells break down sugars and produce the metabolic acid lactate at a much higher rate than normal cells. This phenomenon provides a telltale sign that cancer is present, via diagnostics such as PET scans, and possibly offers an avenue for novel cancer therapies. Now a team of Chilean researchers and Carnegie’s Wolf Frommer have devised a molecular sensor that can detect levels of lactate in individual cells in real time.

First High-resolution National Carbon Map—Panama
A Carnegie-led team of researchers has for the first time mapped the above ground carbon density of an entire country in high fidelity. They integrated field data with satellite imagery and high-resolution airborne Light Detection and Ranging data to map and quantify carbon stocks throughout the Republic of Panama. The results are the first maps that report carbon stocks in areas as small as a hectare (2.5 acres) with the lowest uncertainty of any carbon-counting approach yet.

Carnegie’s Dave Mao awarded AGU’s Inge Lehmann Medal
The American Geophysical Union has awarded Carnegie's Ho-kwang (Dave) Mao the Inge Lehmann Medal for "outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth's mantle and core." Mao has been a pioneer in high-pressures physics and related technology development for over 30 years...

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.

Found: Planets Skimming a Star’s Surface
A new planet-hunting survey has revealed planetary candidates with orbital periods as short as four hours and so close to their host stars that they are nearly skimming the stellar surface. If confirmed, these candidates would be among the closest planets to their stars discovered so far. Brian Jackson of the Carnegie Institution for Science’s Department of Terrestrial Magnetism will present his team’s findings, which are based on data from NASA’s Kepler mission, at the American Astronomical Society’s Division of Planetary Sciences meeting.

Corralling the carbon cycle
Scientists, including Global Ecology’s Joe Berry, may have overcome a major hurdle to calculating how much carbon dioxide is absorbed and released by plants, vital information for determining the amount of carbon that can be safely emitted by human activities. The problem is that ecosystems simultaneously take up and release CO2. The key finding is that the compound carbonyl sulfide, which plants consume in tandem with CO2, can be used to quantify gas flow into the plants during photosynthesis.

Researchers Explain Nitrogen Paradox in Forests
Nitrogen is essential to all life on Earth, and the processes by which it cycles through the environment may determine how ecosystems respond to global warming. But certain aspects of the nitrogen cycle in temperate and tropical forests have puzzled scientists, defying, in a sense, the laws of supply and demand. Now scientists from the Carnegie Institution have explained the paradox by recognizing the role of two other factors: temperature and the abundance of another key element, phosphorous.

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.
