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.

Squeezed Crystals Deliver More Volts Per Jolt
A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics to green energy technologies.

From Lab Dishwasher to Distinguished Researcher
Dianne Williams of Baltimore was hired by Carnegie’s Department of Embryology to wash lab dishes as part of a city job program for inner city youth in 1983. Now as head technician and manager of a Drosophila research lab, and with two degrees from Johns Hopkins University, she has authored four scientific papers and has been acknowledged on countless others. She will receive the Carnegie Service to Science Award on May 5, 2010, for her contributions

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.

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.

Future Warming: Issues of Magnitude and Pace
Researchers reviewed the likelihood of continued changes to the terrestrial climate, including an analysis of a collection of 27 climate models. If emissions of heat-trapping gases continue along the recent trajectory, 21st century mean annual global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during 2046 to 2065 and 7.2 °F (4 °C) during 2081-2100.At this pace, it will probably be the most rapid large climate change in the last 65 million years.

New Stars from Old Gas Surprise Astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. The unexpected discovery comes thanks to instruments aboard NASA’s Galaxy Evolution Explorer (GALEX) spacecraft which are sensitive to the ultraviolet radiation emitted by newly formed stars.

Global Ecology’s Field and Caldeira Major Contributors to Nobel-winning Climate Panel
Carnegie scientists Chris Field and Ken Caldeira of the Department of Global Ecology are key contributors in the UN panel awarded the 2007 Nobel Peace Prize on October 12 for work on global climate change. The International Panel on Climate Change (IPCC) shares the prize with former vice president Al Gore for his role in communicating the issue to the public.

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.

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.

Mercury’s Contraction Much Greater Than Thought
New global imaging and topographic data from MESSENGER show that the innermost planet has contracted far more than previous estimates.The findings are key to understanding the planet’s thermal, tectonic, and volcanic history, and the structure of its unusually large metallic core. “These new results resolved a decades-old paradox between thermal history models and estimates of Mercury’s contraction,” remarked lead author of the study, Paul Byrne.

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.

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.

Carnegie donates landmark clones to biology
Surprisingly little is known about the interactions that proteins have with each other and the protective membrane that surrounds a cell. These membrane proteins regulate nutrients, sense environmental threats, and are the communications interface between and within cells. Now researchers at Plant Biology have cloned genes to produce membrane proteins that may initiate instructions for genes to turn on in the nucleus. They just donated 2010 of them to the Arabidopsis Biological Resource Center.
