Magnesium oxide: From Earth to super-Earth
The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by Carnegie’s Stewart McWilliams studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.

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.

2005 Science Breakthrough: Revising Earth’s Early History
Researchers at the Carnegie’s Department of Terrestrial Magnetism (DTM) found that Earth’s mantle separated into chemically distinct layers faster and earlier than previously believed. Science magazine recognized the work in its December 23 issue, as one of the science breakthroughs for 2005...

Perú’s Carbon Quantified: Economic and Conservation Boon
Today a team, led by Greg Asner, unveiled the first high-resolution map of the carbon stocks stored on land throughout the entire country of Perú. The new and improved methodology used to make the map marks a sea change for future market-based carbon economies. The new carbon map also reveals Perú’s extremely high ecological diversity and it provides the critical input to studies of deforestation and forest degradation for conservation, land use, and enforcement purposes.

Mysterious quasar sequence explained
Quasars are supermassive black holes that live at the center of distant massive galaxies. They shine as the most luminous beacons in the sky across the entire electromagnetic spectrum by rapidly accreting matter into their gravitationally inescapable centers. New work from Carnegie solves a quasar mystery that astronomers have been puzzling over for 20 years. It shows that most observed quasar phenomena can be unified with two simple quantities: one that describes how efficiently the hole is being fed, and the other that reflects the viewing orientation of the astronomer.

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.

Planet-like object may have spent its youth as hot as a star
Astronomers have discovered an extremely cool object that could have a particularly diverse history—although it is now as cool as a planet, it may have spent much of its youth as hot as a star. The current temperature of the object is intermediate between that of the Earth and of Venus. However, the object shows evidence implying that a potentially large change in temperature has taken place. In the past this object would have been as hot as a star for many millions of years.

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.

World’s Most Advanced Telescope Mirror Completed
Washington, D.C.--Scientists with the Giant Magellan Telescope Organization have completed the most challenging large astronomical mirror ever made. The mirror will be part of the 25-meter Giant Magellan Telescope (GMT), which will explore planets around other stars and the formation of stars, galaxies and black holes in the early universe.
