Breakthrough in Monitoring Tropical Deforestation Announced in Copenhagen
New technology, developed by a team of scientists at Carnegie’s Department of Global Ecology, is revolutionizing forest monitoring by marrying free satellite imagery and powerful analytical methods in an easy-to-use, desktop software package called CLASlite. Thus far, 70 government, non-government, and academic organizations in five countries have adopted the technology, with more on the horizon. The team announced its new web site for CLASlite users at the Copenhagen climate meetings today (http://claslite.ciw.edu).

New technique will accelerate genetic characterization of photosynthesis
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. We do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism. A team of researchers has developed a highly sophisticated tool that will transform the work of plant geneticists by addressing this problem and making large-scale genetic characterization of a photosynthetic algae possible for the first time.

Extreme melting event defines Earth’s early history
Could Earth have had an even more violent infancy than previously imagined? New isotope data suggest that the Earth not only had a very violent beginning but also point to new information about our planet’s chemical evolution...

Australia Gets $72 Million for the GMT
The Australian government has announced that it will provide $88.4 million AUD ($72.4 million USD) to help fund the revolutionary 25-meter Giant Magellan Telescope (GMT) to be sited at Las Campanas Observatory in Chile’s high-altitude Atacama Desert. This brings the funding that has been raised to date to $200 million out of approximately $700 million total needed to complete construction, which is scheduled for 2019.

Carnegie’s Arthur Grossman Receives Gilbert Morgan Smith Medal
The National Academy of Sciences has awarded Arthur Grossman, of the Carnegie Institution’s Department of Plant Biology, the 2009 Gilbert Morgan Smith Medal “in recognition of excellence in published research on marine or freshwater algae.” The award was established through the Helen P. Smith Fund.

Calcium and reproduction go together
Everyone’s heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team reports discoveries in the chemical signaling process that guides flowering plant fertilization.

Stem cell surprise for tissue regeneration
Scientists working at the Carnegie Institution’s Department of Embryology have overturned previous research that identified critical genes for making muscle stem cells. It turns out that the genes that make muscle stem cells in the embryo are surprisingly not needed in adult muscle stem cells to regenerate muscles after injury. The finding challenges the current course of research into muscular dystrophy, muscle injury, and regenerative medicine; it also favors using age-matched stem cells for therapy.

New technique reveals supernova progenitor
Wolf-Rayet stars are very large and very hot. Astronomers have long wondered whether Wolf-Rayet stars are the progenitors of certain types of supernovae. New work has identified a Wolf-Rayet star as the likely progenitor of a recently exploded supernova.

Revisiting 1950s experiments for signs of life’s origin
In the 1950s, biochemist Stanley Miller performed a series of experiments to demonstrate that organic compounds could be created under conditions mimicking the primordial Earth. Some unused samples from Miller’s research were recently uncovered by a team of scientists, including Jim Cleaves, of Carnegie’s Geophysical Laboratory. Their findings, carried out using modern techniques , indicate the possible importance of volcanoes and sulfur in the formation of amino acids, and possibly life, on earth.

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.

Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission. New research found unexpected superconductivity that could help scientists better understand the structural changes that create this rare phenomenon.

Carnegie debuts revolutionary biosphere mapping capability at AGU
Researchers from the Carnegie Institution are rolling out results from the new Airborne Taxonomic Mapping System, or AToMS, for the first time at the American Geophysical Union (AGU) meetings in San Francisco. The groundbreaking technology and its scientific observations are uncovering a previously invisible ecological world. To watch a video about how AToMS is helping researchers look at the world in a whole new way, click here.

Disappearing and reappearing superconductivity surprises scientists
Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials at low temperatures, or can be induced under chemical and high external pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission. New work demonstrates unexpected superconductivity in a type of compounds called iron selenium chalcogenides.

Mercury’s Surprising Core and Landscape Curiosities
As reported in one of two papers published today on Science Express, scientists have found that Mercury’s core, already suspected to occupy a greater fraction of the planet's interior than do the cores of Earth, Venus, or Mars, is even larger than anticipated. The companion paper shows that the elevation ranges on Mercury are much smaller than on Mars or the Moon and indicates that there have been large-scale changes to Mercury’s topography since early in the planet’s geological history.

Carnegie Wins DOE Energy Frontier Research Center Award
The Carnegie Institution’s Geophysical Laboratory has been selected as one of 46 Energy Frontier Research Centers (EFRCs) by the U.S. Department of Energy. The five-year, $15.0 million award will establish the Energy Frontier Research in Extreme Environments center (EFree) at the Geophysical lab. The selection was based on the lab’s long legacy of research into materials under extreme pressure and temperature environments.

Ancient Earth crust stored in deep mantle
Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago.

New Planet-weighing Technique Found
Although there have been about 800 extra-solar planets discovered so far in our galaxy, the precise masses of the majority of them are still unknown, as the most-common planet-finding technique provides only a general idea of an object’s mass. Previously, the only way to determine a planet’s exact mass was if it transits—has an orbit that periodically eclipses that of its host star. Former Carnegie scientist Mercedes López-Morales has, for the first time, determined the mass of a non-transiting planet.
