Why Are Some Cells More Cancer Prone?
Cells in the body wear down over time and die. In many organs, like the small intestine, adult stem cells play a vital role in maintaining function by replacing old cells with new ones. Learning about the nature of tissue stem cells can help scientists understand exactly how our organs are built, and why some organs generate cancer frequently, but others only rarely. New work from Carnegie’s Alexis Marianes and Allan Spradling used some of the most experimentally accessible tissue stem cells, the adult stem cells in the midsection of the fruit fly gut, with surprising results.

Where on Earth Did the Moon’s Water Come From?
Water is perhaps the most important molecule in our solar system. Figuring out where it came from and how it was distributed within and among the planets can help scientists understand how planets formed and evolved. New research from a team including Carnegie’s Erik Hauri demonstrates that water from the interiors of the Earth and Moon has a common origin.

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria  by mid-century if emissions are not dramatically curtailed now.

Plant Scientists Participate in DOE Energy Frontier Research Center
The Carnegie Institution’s Department of Plant Biology is a major participant in a newly-funded Department of Energy Frontier Research Center (EFRC) at Stanford University. The new EFRC, called the Center on Nanostructuring for Efficient Energy Conversion, will conduct basic research on developing new materials and technologies for meeting energy needs while reducing emission of greenhouse gases.

New web resource to improve crop engineering
The Carnegie Institution’s Department of Plant Biology today announced the launch of a new web-based resource that promises to help researchers around the world meet increasing demands for food production, animal feed, biofuels, industrial materials, and new medicines. It is the Plant Metabolic Network (PMN) at http://www.plantcyc.org/

Oceanic crust breakthrough: solving a magma mystery
Oceanic crust covers two-thirds of the Earth’s solid surface, but scientists still don’t entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust by a team including Carnegie’s Frances Jenner reveals a systemic pattern that alters long-held beliefs about how this process works, explaining a crucial step in understanding Earth’s geological deep processes.

Two planets orbit nearby ancient star
An international team of astronomers, including five Carnegie scientists, reports the discovery of two new planets orbiting a very old star that is near to our own Sun. One of these planets orbits the star at the right distance to allow liquid water to exist on its surface, a key ingredient to support life.

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

Controlling a sea of information
Curators at one of the world’s most widely used biological databases, The Arabidopsis Information Resource, or TAIR, have joined forces with the journal Plant Physiology, to solve the “flood of information” dilemma.

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.

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.

D. C. Math for America Awarded $1. 5-Million NSF Grant
In 2008, The Carnegie Institution’s Carnegie Academy for Science Education (CASE) launched a partnership with Math for America (MfA) and American University. The program is to improve the mathematics education of Washington, D.C., public and public charter secondary school students by selecting and educating fellows to become skilled teachers. Using stimulus funds, the National Science Foundation has just awarded MfA DC a $ 1.498-million grant to cover costs for the first 14 fellows.

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.

Carnegie’s Christoph Lepper Receives Prestigious Early Independence Award
Staff associate Christoph Lepper, at Carnegie’s Department of Embryology, is one of 10 recipients of the NIH Director’s Early Independence Awards. This is the first year of the awards. Lepper will receive a prize of $250,000 per year for five years to carry out his creative research program as an independent investigator. The prize is designed to launch exceptional young scientists into independent positions directly out of graduate school.

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.
