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.

Mercury Not Like Other Planets MESSENGER Finds
The MESSENGER spacecraft has shown scientists that Mercury doesn’t conform to theory. Its surface material composition differs from both those of the other terrestrial planets and expectations prior to the MESSENGER mission, calling into question current theories for Mercury’s formation. Its magnetic field is unlike any other in the Solar System, and there are huge expanses of volcanic plains surrounding the north polar region of the planet and cover more than 6% of Mercury’s surface.

Young graphite, old rocks: looking for evidence of earliest life
Scientists have long debated about the origin of carbon in Earth’s oldest sedimentary rocks and how it might signal the remnants of the earliest forms of life on the planet. New research by a team including five scientists from Carnegie’s Geophysical Laboratory and Department of Terrestrial Magnetism discovered that carbon samples taken from ancient Canadian rock formations are younger than the sedimentary rocks surrounding them, which were formed at least 3.8 billion years ago. Their results indicate that the carbon contained in such ancient rocks should not be assumed to be as old as the rocks, unless it can be shown to have had the same metamorphic history as the host rock.

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.

Ultra-distant galaxy spied amidst cosmic “Dark Ages”
With the combined power of NASA's Spitzer and Hubble Space Telescopes, as well as a cosmic magnification effect, a team of astronomers, including Carnegie’s Daniel Kelson, have spotted what could be the most distant galaxy ever seen. Light from the young galaxy captured by the orbiting observatories was emitted when our 13.7-billion-year-old universe was just 500 million years old.

Carnegie Institution and UMASS Medical School Granted Broad U.S. Patent Related to RNA Interference
The Carnegie Institution for Science and the University of Massachusetts Medical School (UMMS) have been granted United States Patent 8,283,329, entitled, “Genetic inhibition of double-stranded RNA.” The patent, issued on October 9, 2012, is broadly directed to the use of RNA interference (RNAi) to inhibit expression of a target gene in animal cells, including mammalian cells.

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.

Carnegie Wins Grant to Probe Earth’s Deep Carbon
The Alfred P. Sloan Foundation has awarded the Carnegie Institution a $4 million grant over three years to initiate the Deep Carbon Observatory -- an international, decade-long project to investigate the nature of carbon in Earth's deep interior.

Delving into manganite conductivity
Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding—and ultimately controlling—this effect remains a challenge, because much about manganite physics is still not known. This new research is an important breakthrough in our understanding of the mysterious ways manganites respond when subjected to intense pressure.

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.

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.

Carnegie’s Field and Koshland Elected AAAS Fellows
Christopher B. Field, director of Carnegie's Department of Global Ecology, and Douglas E. Koshland, staff scientist at the Department of Embryology, have been elected AAAS Fellows by the American Association for the Advancement of Science. The announcement appears in the News & Notes section of the December19, 2008 issue of Science.

Man in the Moon Looking Younger
Earth’s Moon could be younger than previously thought, according to new research. The prevailing theory of our Moon’s origin is that it was created by a giant impact between a large planet-like object and the proto-Earth. The energy of this impact was sufficiently high that the Moon formed from melted material that was ejected into space. As the Moon cooled, this magma solidified into different mineral components. Analysis of lunar rock samples thought to have been derived from the original magma has given scientists a new estimate of the Moon’s age.

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.
