Climate Change Alters Ocean Chemistry
Researchers have discovered that the ocean’s chemical makeup is less stable and more greatly affected by climate change than previously believed. A study in the December 12, 2008 issue of Science reports that during a time of climate change 13 million years ago the chemistry of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be similarly affected by climate changes now underway – with potentially far-reaching consequences for marine ecosystems.

Carnegie Partners with USA Science & Engineering Festival for Second Year
The world's largest celebration of science and engineering, the USA Science & Engineering Festival, will return to Washington, D.C., April 27-29, 2012. For the second year, the Carnegie Institution for Science will participate with hands-on experiments. At Carnegie's booth last year, visitors prospected for microscopic diamonds, handled a meteorite, constructed a spectroscope, examined fossils that are more than a billion years old, and met the scientists who do the work.

Carnegie’s Christopher Field To Receive Heinz Award
Palo Alto, CA— Christopher Field, director of the Carnegie Institution’s Department of Global Ecology, has been awarded a prestigious Heinz award. The awards were established by Teresa Heinz in 1993 to honor her late husband, U.S. Senator John Heinz, by recognizing “extraordinary achievements of individuals in the areas of greatest importance to him.”

Abandoned Farmlands Are Key to Sustainable Bioenergy
Biofuels can be a sustainable part of the world’s energy future, especially if bioenergy agriculture is developed on currently abandoned or degraded agricultural lands, report scientists from the Carnegie Institution and Stanford University. Using these lands for energy crops, instead of converting existing croplands or clearing new land, avoids competition with food production and preserves carbon-storing forests needed to mitigate climate change.

How do you make lithium melt in the cold?
Sophisticated tools allow scientists to subject the basic elements of matter to conditions drastic enough to modify their behavior. By doing this, they can expand our understanding of matter. A research team including three Carnegie scientists was able to demonstrate surprising properties of the element lithium under intense pressure and low temperatures.

Carnegie’s Ho-kwang (Dave) Mao Elected to Royal Society of London
Carnegie Institution scientist Ho-kwang (Dave) Mao has been elected as a Foreign Member of the Royal Society of London, the National Academy of the United Kingdom and one of the world’s most prestigious scientific societies. The society cites Mao’s “extraordinary creative impact” in high-pressure science and related technology development for over 40 years. The induction ceremony will take place in London on July 11, 2008.

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.

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.

Studying Ancient Earth’s Geochemistry
Researchers still have much to learn about the volcanism that shaped our planet’s early history. New evidence from a team led by Carnegie’s Frances Jenner demonstrates that some of the tectonic processes driving volcanic activity, such as those taking place today, were occurring as early as 3.8 billion years ago.

Gut bacteria increase fat absorption
You may think you have dinner all to yourself, but you’re actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie’s Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats, allowing the host organism to extract more calories from the same amount of food.

Roller Coaster Superconductivity Discovered
Superconductors are more efficient at carrying electricity than copper wires. But these materials have to be cooled below an extremely low, so-called transition temperature for electrical resistance to disappear. Researchers at the Carnegie’s Geophysical Laboratory, have unexpectedly found that the transition temperature can be induced under two different intense pressures in a three-layered bismuth oxide crystal. They believe this unusual two-step phenomena comes from competition of electronic behavior in different layers.

Forest Carbon Monitoring Breakthrough in Colombia
Using new techniques, Carnegie and Colombian scientists have developed ultra-high resolution maps of the carbon stocks locked in tropical vegetation for 40% of the Colombian Amazon, an area about four times the size of Switzerland. Until now, the inability to accurately quantify carbon stocks at high spatial resolution over large areas has hindered the United Nations’ Reducing Emissions from Deforestation and Forest Degradation (REDD+) program aimed at creating a financial value for storing carbon in tropical forests.

Probing hydrogen under extreme conditions
How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work from Carnegie scientists has enabled researchers to examine hydrogen under pressures never before possible.

Tail discovered on long-known asteroid
A two-person team of Carnegie's Scott Sheppard and Chadwick Trujillo of the Gemini Observatory has discovered a new active asteroid, called 62412, in the Solar System's main asteroid belt between Mars and Jupiter. It is the first comet-like object seen in the Hygiea family of asteroids. Active asteroids are a newly recognized phenomenon. 62412 is only the 13th known active asteroid in the main asteroid belt. Sheppard and Trujillo estimate that there are likely about 100 of them in the main asteroid belt, based on their discovery.

Airborne Ecologists Help Balance Delicate African Ecosystem
The African savanna is world famous for its wildlife, especially the iconic large herbivores such as elephants, zebras, and giraffes. But managing these ecosystems and balancing the interests of the large charismatic mammals with those of other species has been a perpetual challenge for park and game mangers. Now a new study published in the Proceedings of the National Academy of Sciences reports the successful test of new remote-sensing technology to monitor the impact of management decisions on the savannah ecosystem.
