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 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.

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 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.

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.

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.

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.

Giant Magellan Telescope Looking Toward Construction
The international consortium of the Giant Magellan Telescope (GMT) project has passed two major reviews and is positioned to enter the construction phase. When completed, the 25-meter GMT will have more than six times the collecting area of the largest telescopes today and ten times the resolution of the Hubble Space Telescope.

Plant Scientists Participate in DOE Energy Frontier Research Center
The Carnegie Institution’s Department of Plant Biology is a major participant in a newly-funded Department of Energy Frontier Research Center (EFRC) at Stanford University. The new EFRC, called the Center on Nanostructuring for Efficient Energy Conversion, will conduct basic research on developing new materials and technologies for meeting energy needs while reducing emission of greenhouse gases.

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.

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.

Donald Brown Receives Lifetime Achievement Award from Society for Developmental Biology
Donald D. Brown, of Carnegie’s Department of Embryology, will receive the 2009 Lifetime Achievement Award from the Society for Developmental Biology. The award is given to “a senior developmental biologist in recognition of her/his outstanding and sustained contributions in the field…[and]for the individual's excellence in research and for being a superb mentor who has helped train the next generation of exceptional scientists.”

Plant research funding crucial for the future
The scientific community needs to make a 10-year, $100 billion investment in food and energy security, says Carnegie’s Wolf Frommer and Tom Brutnell of the Donald Danforth Plant Science Center in an opinion piece published in the June issue of The Scientist. They say the importance of addressing these concerns in light of a rapidly growing global population is on par with President John Kennedy’s promise to put man on the moon—a project that took a decade and cost $24 billion.

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.

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.
