Possible muscle disease therapeutic target found
The study of muscular system protein myostatin has been of great interest to researchers as a potential therapeutic target for people with muscular disorders. Although much is known about how myostatin affects muscle growth, there has been disagreement about what types of muscle cells it acts upon. New research from a team including Carnegie's Chen-Ming Fan and Christoph Lepper narrows down the field to one likely type of cell.

Scientists Find Moon Whiskers
Up to now scientists thought that the trace carbon on the surface of the Moon came from the solar wind. Now researchers at the Geophysical Lab have detected and dated Moon carbon in the form of graphite, which survived from the late heavy bombardment era 3.8 billion years ago. The discovery means that the Moon could hold a record of the meteoritic carbon input to the Earth-Moon system, when life was just beginning to emerge. Multimedia version

New Possibilities for Hydrogen-Producing Algae
Photosynthesis produces the food that we eat and the oxygen that we breathe ― could it also help satisfy our future energy needs by producing clean-burning hydrogen? Researchers studying a hydrogen-producing, single-celled green alga, Chlamydomonas reinhardtii, have unmasked a previously unknown fermentation pathway that may open up possibilities for increasing hydrogen production.

Nanotechnology Imaging Breakthrough
A team led by Carnegie researcher Wenge Yang has made a major breakthrough in measuring the structure of nanomaterials under extremely high pressures. They developed a new way to get around the severe distortions of high-energy X-ray beams that are used to image the structure of a gold nanocrystal. The technique could lead to advancements of new nanomaterials created under high pressures and a greater understanding of what is happening in planetary interiors.

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.

Carnegie’s Dave Mao awarded AGU’s Inge Lehmann Medal
The American Geophysical Union has awarded Carnegie's Ho-kwang (Dave) Mao the Inge Lehmann Medal for "outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth's mantle and core." Mao has been a pioneer in high-pressures physics and related technology development for over 30 years...

Acidifying Oceans Add Urgency to CO2 Cuts
Stanford, CA— It’s not just about climate change anymore. Besides loading the atmosphere with heat-trapping greenhouse gases, human emissions of carbon dioxide have also begun to alter the chemistry of the ocean—often called the cradle of life on Earth. The ecological and economic consequences are difficult to predict but possibly calamitous, warn a team of chemical oceanographers in the July 4 issue of Science, and halting the changes already underway will likely require even steeper cuts in carbon emissions than those currently proposed to curb climate change.

Future of biology rests in harnessing data avalanche
Like most sciences, biology is inundated with data. However, researchers, including Sue Rhee at Plant Biology, warn in a Nature feature that the avalanche of biological information is at the point where the discipline may be unable to reach its full potential without improvements for curating data into on-line databases. The piece outlines specific remedies to harness the information overload.

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.

Researchers Explain Nitrogen Paradox in Forests
Nitrogen is essential to all life on Earth, and the processes by which it cycles through the environment may determine how ecosystems respond to global warming. But certain aspects of the nitrogen cycle in temperate and tropical forests have puzzled scientists, defying, in a sense, the laws of supply and demand. Now scientists from the Carnegie Institution have explained the paradox by recognizing the role of two other factors: temperature and the abundance of another key element, phosphorous.

The Smoking Gun: Fish Brains and Nicotine
In researching neural pathways, it helps to establish an analogous relationship between a region of the human brain and the brains of more-easily studied animal species. New work from a team led by Carnegie’s Marnie Halpern hones in on one particular region of the zebrafish brain that could help us understand the circuitry underlying nicotine addiction.

Australia Gets $72 Million for the GMT
The Australian government has announced that it will provide $88.4 million AUD ($72.4 million USD) to help fund the revolutionary 25-meter Giant Magellan Telescope (GMT) to be sited at Las Campanas Observatory in Chile’s high-altitude Atacama Desert. This brings the funding that has been raised to date to $200 million out of approximately $700 million total needed to complete construction, which is scheduled for 2019.

Exoplanet Formation Surprise
A team of researchers has discovered evidence that an extrasolar planet may be forming quite far from its star—about twice the distance Pluto is from our Sun. The planet lies inside a dusty, gaseous disk around a small red dwarf TW Hydrae, which is only about 55% of the mass of the Sun. The discovery adds to the ever-increasing variety of planetary systems in the Milky Way.

Corralling the carbon cycle
Scientists, including Global Ecology’s Joe Berry, may have overcome a major hurdle to calculating how much carbon dioxide is absorbed and released by plants, vital information for determining the amount of carbon that can be safely emitted by human activities. The problem is that ecosystems simultaneously take up and release CO2. The key finding is that the compound carbonyl sulfide, which plants consume in tandem with CO2, can be used to quantify gas flow into the plants during photosynthesis.

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.
