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.

Preventing Climate Change: The Size of the Energy Challenge
In 2004 a very popular study aimed to address climate change by deploying wedges of different existing energy technologies or approaches. According to the study by Robert Socolow and Stephen Pacala, each wedge would avoid one billion tons of carbon (1 GtC) emissions per year after 50 years. The study showed that, at that time, seven wedges could stabilize carbon dioxide emissions relative to what would happen if things remained “business-as-usual.” A new perspective paper from a group including Carnegie’s Ken Caldeira uses the wedge approach to estimate the size of the energy challenge posed by climate change today.

No Redoubt: Volcanic Eruption Forecasting Improved
Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns. New research from a team led by Carnegie’s Diana Roman retrospectively documented and analyzed the period immediately preceding the 2009 eruption of the Redoubt volcano in Alaska, which was characterized by an abnormally long period of pre-eruption seismic activity that’s normally associated with short-term warnings of eruption.

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.

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.

New clues to the early Solar System from ancient meteorites
In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from a team including Carnegie scientists focuses on one particularly old type of meteorite called diogenites. These samples were examined using an array of techniques, including precise analysis of certain elements for important clues to some of the Solar System's earliest chemical processing.

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.

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

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.

Exoplanet Atmospheres Detected from Earth
Two independent groups have simultaneously made the first-ever ground-based detection of extrasolar planets thermal emissions. Until now, virtually everything known about atmospheres of planets orbiting other stars in the Milky Way has come from space-based observations. These new results, accepted for publication in Astronomy & Astrophysics, open a new frontier to studying these alien worlds and are especially critical because the major space-based workhorse to these studies, the Spitzer telescope, will soon run out of cryogens, highly limiting its capabilities.

Carnegie’s Richard Meserve Awarded Nuclear Industry Leadership Prize
Carnegie President Richard A. Meserve received the William S. Lee Award for Leadership at the Nuclear Energy Institute’s (NEI) annual conference on May 22. NEI President and CEO Marvin Fertel observed, “[Meserve's] tireless contributions to the paramount issue of safety in the nuclear energy industry have been immeasurable. He’s one of the most well-respected figures in the nuclear field on any continent." For more information see the Nuclear Energy Institute press release.

Educational Pioneer BioEYES Goes Down Under
The innovative, educational, outreach program BioEYES has now been adopted by Monash University and the Australian Regenerative Medicine Institute. The down-under partnership program debuts this August. BioEYES is designed to foster an interest in and a love for science in elementary, middle, and high school students. Over the course of one week, students watch the transparent zebrafish, Danio rerio, grow from a single-celled zygote to a larval fish complete with a beating heart.

Some galaxies in the early universe grew up quickly
Some galaxies grew up in a hurry. Most of the galaxies that have been observed from the early days of the universe were young and actively forming stars. Now, an international team of astronomers, including Carnegie’s Eric Persson and Andy Monson, have discovered galaxies that were already mature and massive in the early days. Fifteen mature galaxies were found at a record-breaking average distance of 12 billion light years, when the universe was just 1.6 billion years old. Their existence at such an early time raises new questions about what forced them to grow up so quickly.

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.

Ancient Galaxy Cluster Contains “Modern” Galaxies
A team of astronomers including Ivelina Momcheva of the Carnegie Observatories has discovered the most distant cluster of galaxies ever found. In a surprising twist, the young cluster born just 2.8 billion years after the Big Bang appears remarkably similar to the much older present-day galaxy clusters

Major Changes Needed For Coral Reef Survival
To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie’s Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be engulfed in inhospitable ocean chemistry conditions by the end of the century if civilization continues along its current emissions trajectory.
