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.

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).

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...

Major Changes Needed For Coral Reef Survival
To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie’s Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be engulfed in inhospitable ocean chemistry conditions by the end of the century if civilization continues along its current emissions trajectory.

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.

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

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.

Future of biology rests in harnessing data avalanche
Like most sciences, biology is inundated with data. However, researchers, including Sue Rhee at Plant Biology, warn in a Nature feature that the avalanche of biological information is at the point where the discipline may be unable to reach its full potential without improvements for curating data into on-line databases. The piece outlines specific remedies to harness the information overload.

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.

Gold Mining Ravages Perú
For the first time, researchers have been able to map the true extent of gold mining in the biologically diverse region of Madre De Dios in the Peruvian Amazon. The team, led by Greg Asner, combined field surveys with airborne mapping and high-resolution satellite monitoring to show that the geographic extent of mining has increased 400% from 1999 to 2012 and that the average annual rate of forest loss has tripled since the Great Recession of 2008. Until this study, thousands of small, clandestine mines that have boomed since the economic crisis have gone unmonitored.
