Exploring Planets in Distant Space and Deep Interiors
In recent years researchers have found hundreds of new planets beyond our solar system, raising questions about the origins and properties of these exotic worlds—not to mention the possible presence of life. Speaking at a symposium titled “The Origin and Evolution of Planets” held at the annual meeting of the American Association for the Advancement of Science, two Carnegie Institution scientists presented their perspectives on the new era of planetary exploration.

Mountaintop Blasting to Mine the Sky with the Giant Magellan Telescope
Astronomers began to blast 3 million cubic feet of rock from a mountaintop in the Chilean Andes today to prepare for the world’s largest telescope at the Carnegie Institution’s Las Campanas Observatory. Over the next few months, more than 70 controlled blasts will break up the rock while leaving a solid bedrock foundation for the telescope and its precision scientific instruments.More information about the telescope is here

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.

Revolution in Rain Forest Monitoring with MacArthur Grant
Tropical rain forests are treasure houses of biodiversity, but there has been no effective way to inventory and monitor their plant species over large areas. As a result, we have limited understanding of how climate change, clearing, invasive plants, and other threats are affecting these delicate ecosystems. A major advance in improving this situation is in the works, however. Gregory Asner of the Carnegie Institution’s Department of Global Ecology was just awarded a $1.8 million grant from the John D. and Catherine T. MacArthur Foundation to create a database of plant chemical and remote sensing signatures for tropical forest species.

Breakthrough in Nanocrystals Growth
For the first time scientists, including researchers with the Geophysical Lab, have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size. Researchers will now be able to develop ways to control conditions under which they are grown. The breakthrough will affect a wide range of applications including solar-cell technology and chemical and biological sensors.

Putting the Squeeze on Nitrogen for High Energy Materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen. Hypothesized nitrogen polymers could form materials with higher energy content than any known non-nuclear material.

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.

Dense Hydrogen in a New Light
Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets. New work from Carnegie scientists using intense infrared radiation shines new light on this fundamental material at extreme pressures and reveals the details of a surprising new form of solid hydrogen.

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.

Progreso excepcional en el mapeo de carbono
Mediante la integración de mapeo satélital, tecnología láser aerotransportada, y estudios a nivel de parcelas, los científicos de la Institución Carnegie Departamento de Ecología de Global, con colegas del Fondo Mundial para la Naturaleza WWF y en coordinación con el Ministerio Peruano del Ambiente (MINAM), han revelado los primeros mapas de alta resolución de carbono almacenado en la vegetación de bosques tropicales y emitido por prácticas de uso de la tierra. Estos nuevos mapas marcan el camino para el monitoreo preciso de el almacenamiento de carbono y emisiones en el marco de la propuesta de las Naciones Unidas para la Reducción de Emisiones por Deforestación y Degradación (REDD).

Plant toughness: Key to cracking biofuels?
Along with photosynthesis, the plant cell wall is one of the features that most set plants apart from animals. A structural molecule called cellulose is necessary for the manufacture of these walls. Cellulose is synthesized in a semi-crystalline state that is essential for its function in the cell wall function, but the mechanisms controlling its crystallinity are poorly understood. New research from a team including current and former Carnegie scientists reveals key information about this process, as well as a means to reduce cellulose crystallinity, which is a key stumbling block in biofuels development.

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.

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.
