New Revelations about Mercury’s Volcanism, Magnetic Substorms, and Exosphere from MESSENGER
Analysis of data from MESSENGER’s third and final flyby of Mercury in September 2009 has revealed evidence of younger volcanism on the innermost planet than previously recognized, new information about magnetic substorms, and the first observations of emission from an ionized species in Mercury’s very thin atmosphere or exosphere.

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.

Carnegie Announces New Science Education Programs
The Carnegie Academy for Science Education (CASE) was awarded a grant to run two special career exploration programs for students who attend public schools in the District of Columbia. The program is called SciLife™-DC.

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.

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.

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.

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.

Gold Mining Ravages Perú
For the first time, researchers have been able to map the true extent of gold mining in the biologically diverse region of Madre De Dios in the Peruvian Amazon. The team, led by Greg Asner, combined field surveys with airborne mapping and high-resolution satellite monitoring to show that the geographic extent of mining has increased 400% from 1999 to 2012 and that the average annual rate of forest loss has tripled since the Great Recession of 2008. Until this study, thousands of small, clandestine mines that have boomed since the economic crisis have gone unmonitored.

Arctic Rocks Offer New Glimpse of Primitive Earth
Scientists have discovered a new window into the Earth's violent past. Geochemical evidence from volcanic rocks collected on Baffin Island in the Canadian Arctic suggests that beneath it lies a region of the Earth's mantle that has largely escaped the billions of years of melting and geological churning that has affected the rest of the planet. Researchers believe the discovery offers clues to the early chemical evolution of the Earth.

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.”

Mellon Awards Carnegie Grant for Ecological Monitoring in South Africa
The Andrew W. Mellon Foundation awarded a $750,000 grant to the Carnegie Institution’s Department of Global Ecology for an intensive pilot study of ecosystem diversity in South Africa’s Kruger National Park. This research will contribute to the park’s “adaptive management” program, which uses science to improve the chances that the park’s ecosystems, including their complex vegetative and animal populations, are sustained into the future.

News briefing: Global warming’s record-setting pace
The pace of global warming over the last century has been about twice as rapid over land than over the oceans and will continue to be more dramatic going forward if emissions are not curbed. According to an analysis of 27 climate models by Carnegie’s Chris Field, if we continue along the current emissions trajectory, we are likely facing the most rapid large climate change in the last 65 million years. This will clearly pose great challenges for a variety of terrestrial ecosystems.

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.

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.

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.

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.
