First super-Earths discovered around Sun-like stars
Two nearby stars have been found to harbor “super-Earths”― rocky planets larger than the Earth but smaller than ice giants such as Uranus and Neptune. Unlike previously discovered stars with super-Earths, both of the stars are similar to the Sun, suggesting to scientists that low-mass planets may be common around nearby stars.

New understanding of Earth’s mantle beneath the Pacific Ocean
Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the lithosphere and underlying asthenosphere. Understanding this boundary is central to our knowledge of plate tectonics and thus the formation and evolution of our planet as we know it today. A new technique for observing this transition, particularly in the portion of Earth’s mantle that lies beneath the Pacific Ocean basin, has led Carnegie and NASA Goddard scientist Nick Schmerr to new insight on the origins of the lithosphere and asthenosphere.

Carnegie Institution in Top 1% of Charities for Best Fiscal Management
Charity Navigator, America's largest charity evaluator, has awarded the Carnegie Institution of Washington its highest rating, 4 stars, for sound fiscal management for 7 years running. Charity Navigator evaluates over 5,300 charities and only 12 have received a 4-star rating 7 years in a row.

George Preston Chosen for 2009 Henry Norris Russell Lectureship
Dr. George W. Preston of the Carnegie Observatories has been selected by the American Astronomical Society to be the 2009 recipient of its highest distinction: the Henry Norris Russell Lectureship. The Russell Lectureship is awarded each year in recognition of a lifetime of excellence in astronomical research. Preston will deliver the lecture at the 2009 winter meeting of the AAS in Washington, D.C.

Honing in on supernova origins
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the explosions happen. New research from a team led by Harvard University and including Carnegie’s Josh Simon, Chris Burns, Nidia Morrell, and Mark Phillips examined 23 Type Ia supernovae and helped identify the formation process for at least some of them.

Geoengineering and global food supply
Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter. There are concerns that a continuation of these trends could have catastrophic effects, including crop failures in the heat-stressed tropics. This has led some to explore drastic ideas for combating global warming, including the idea of trying to counteract it by reflecting sunlight away from the Earth. However, it has been suggested that reflecting sunlight away from the Earth might itself threaten the food supply of billions of people. New research led by Carnegie’s Julia Pongratz examines the potential effects that geoengineering the climate could have on global food production and concludes that sunshade geoengineering would be more likely to improve rather than threaten food security.

High Pressure Yields Novel Single-Element ‘Compound’
An international team of researchers including scientists at the Carnegie Institution has discovered a new chemical compound that consists of a single element―boron. Chemical compounds are conventionally defined as substances consist of two or more elements, but the researchers found that a high pressure and temperature pure boron can assume two distinct forms that bond together to create a novel “compound” that can be described as boron boride.

Carnegie Ranked Top Charity 12 Years Running
The Carnegie Institution for Science received the highest rating for sound fiscal management and commitment to accountability and transparency—four stars—from Charity Navigator for the twelfth consecutive year. Charity Navigator is America's largest charity evaluator. Only five organizations out of the 5,500 evaluated have received this highest rating for this long.

Rain forest protection works in Peru
Stanford, CA—A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. Scientists at the Carnegie Institution’s Department of Global Ecology led an international effort to analyze seven years of high-resolution satellite data covering most (79%) of the Peruvian Amazon for their findings. The work is published in the Science Express.

Extremely Rare Triple Quasar Found
For only the second time in history, a team of scientists--including Carnegie's Michele Fumagalli--have discovered an extremely rare triple quasar system. Their work is published by Monthly Notices of the Royal Astronomical Society.

Caldeira, Fei, and Shirey Elected AGU Fellows
Carnegie scientists Kenneth Caldeira of the Department of Global Ecology, Yingwei Fei of the Geophysical Laboratory, and Steven Shirey of the Department of Terrestrial Magnetism have been elected 2010 Fellows of the American Geophysical Union (AGU). Election to Fellowship each year honors scientists who “have attained acknowledged eminence in the Earth and space sciences.”

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.

Carnegie’s Larry Nittler Elected Meteoritical Fellow
Department of Terrestrial Magnetism (DTM) staff member Larry Nittler has been elected a fellow of the Meteoritical Society. Society fellows are “members who have distinguished themselves in meteoritics or allied sciences.” Just one percent of the membership can be elected by the society’s council on even-numbered years.

New Technology Needed to Monitor Rain Forest “Tsunami”
Human impact on tropical forest ecosystems has reached a “tsunami” stage, say scientists, and will require a new generation of sophisticated remote-sensing technology to monitor the changes. Speaking at a Smithsonian symposium Gregory Asner of the Carnegie Institution’s Department of Global Ecology presented new estimates of the global human impact on rain forests, including not only deforestation but also the extent of selective logging and forest regeneration.

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.

Classic Experiments Give New Insight on Life’s Origin
The building blocks of life may have emerged in volcanic eruptions on the early Earth, according to a new analysis of classic experiments performed more than fifty years ago. Using modern techniques to examine samples from the original experiments, researchers discovered previously undetectable organic compounds. The results, reported in the October 17 issue of Science, point to the possible contribution of volcanism to the beginning of life on Earth.
