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.

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 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.”

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.

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.

A Solar System Family Portrait, from the Inside Out
The MESSENGER spacecraft has captured the first portrait of our Solar System from the inside looking out. Comprised of 34 images, the mosaic provides a complement to the Solar System portrait – that one from the outside looking in – taken by Voyager 1 in 1990.

Supernova progenitor found?
Type Ia supernovae are violent stellar explosions. Observations of their brightness are used to determine distances in the universe and have shown scientists that the universe is expanding at an accelerating rate. But there is still too little known about the specifics of the processes by which these supernovae form. New research led by Carnegie identifies a star, prior to explosion, which will possibly become a type Ia supernova.

Silver Tells a Volatile Story of Earth’s Origin
Tiny variations in the isotopic composition of silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 billion years ago. The new study, published in the journal Science, indicates that water and other key volatiles may have been present in at least some of Earth’s original building blocks, rather than acquired later from comets, as some scientists have suggested.

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.

Drought hormones measured
Floods and droughts are increasingly in the news, and climate experts say their frequency will only go up in the future. As such, it is crucial for scientists to learn more about how these extreme events affect plants in order to prepare for and combat the risks to food security that could result. New work from Carnegie will allow researchers, for the first time, to measure the levels of a plant hormone involved in responses to drought stress in individual plant cells in real time.

Surprise: Typhoons Trigger Slow Earthquakes
Scientists have made the surprising finding that typhoons trigger slow earthquakes, at least in eastern Taiwan. Slow earthquakes are non-violent fault slippage events that take hours or days instead of a few brutal seconds to minutes to release their potent energy. The researchers discuss their data in a study published in the June 11, issue of Nature.

Carnegie Wins Grant to Preserve Historic Photos
The Carnegie Institution has been awarded a $9,400 grant from the Center for History of Physics, American Institute of Physics, to preserve and enhance access to a collection of historic photographs of scientific instruments and apparatus in the archives of the Department of Terrestrial Magnetism (DTM). The collection spans five decades from 1904 to the 1950s and includes thousands of images important to the history of geophysics, atomic physics, and astronomy.

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.
