Diamonds Reveal Deep Source of Platinum Deposits
The world’s richest source of platinum and related metals is an enigmatic geological structure in South Africa known as the Bushveld Complex. This complex of ancient magmas is known to have formed some two billion years ago, but the source of its metallic riches has been a matter of scientific dispute. Now researchers from the Carnegie Institution and the University of Cape Town have traced the origin of the unique ore deposits by using another of South Africa’s treasures—diamonds.

Scientists Tackle the Carbon Conundrum
Scientists, including Carnegie's Anna Michalak, have developed a new, integrated, ten-year science plan to better understand the details of Earth’s carbon cycle. It identifies new research areas such as the role of humans as agents and managers of carbon cycling and climate change, the direct impact of greenhouse gases on ecosystems including changes to plant and animal diversity and ocean acidification, the need to address social concerns, and how best to communicate results to the public and decision makers.

Chromosome “Glue” Surprises Scientists
Proteins called cohesins ensure that newly copied chromosomes bind together, separate correctly during cell division, and are repaired efficiently after DNA damage. Scientists at the Carnegie Institution have found that cohesins are needed in different concentrations for their different functions. This discovery helps to explain how certain developmental disorders, arise without affecting cell division essential to development. The research was made possible by a new technique developed by the scientists.

Spectacular Heating of Planet Observed
Here on Earth we worry about our planet's atmosphere warming by a few degrees on average over the next century, and even weather fronts bring temporary changes in temperature of no more than tens of degrees. Now astronomers writing in the January 29 Nature
report on an extra-solar planetary system where global warming is taken to a spectacular extreme: a 700 degree rise in a few hours.

Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars—the most common type of star in the galaxy—are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn’t conform. It has an unusually active and complex magnetic field, stronger than our own Sun’s, and a huge hot spot that covers half of its surface.

Earth’s getting “soft” in the middle
A new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly, suggesting that the material there is softer than previously thought.

Carnegie’s Rubén Rellán-Álvarez Receives Young Scientist Award
Postdoctoral fellow Rubén Rellán-Álvarez, at the Department of Plant Biology, has been awarded the prestigious Marschner Young Scientist Award by the International Plant Nutrition Colloquium. The award was established for “outstanding Ph.D. students and early-career researchers with the potential to become future research leaders.”

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.

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.

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/

Communicating with the world across the border
All living cells are held together by membranes, which provide a barrier to the transport of nutrients. They are also the communication platform connecting the outside world to the cell’s interior control centers. Thousands of proteins reside in these cell membranes and control the flow of select chemicals, which move across the barrier and mediate the flux of nutrients and information. Little was known about the relationships among membrane proteins and interior proteins. A team of scientists has revealed how membrane proteins were networked with each other and with the signaling proteins inside the cell.

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.

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

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.

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.
