Under Pressure, Atoms Make Unlikely Alloys
Ever since the Bronze Age, humans have experimented with combining different metals to create alloys with properties superior to either metal alone. But not all metals readily form alloys – for some pairs of elements the atoms are too dissimilar. Now researchers in an international team have discovered that previously impossible alloys can be created by subjecting atoms to high pressure―opening up possibilities for new materials in the future.

Ancient Minerals: Which Gave Rise to Life?
Life originated as a result of natural processes that exploited early Earth’s raw materials. Scientific models of life’s origins almost always look to minerals for such essential tasks as the synthesis of life’s molecular building blocks or the supply of metabolic energy. But this assumes that the mineral species found on Earth today are much the same as they were during Earth’s first 550 million years—the Hadean Eon—when life emerged. A new analysis of Hadean mineralogy challenges that assumption.

Geoscience converges under pressure
The contents of the deep Earth affect the planet as a whole, including life at its surface, but scientists must find unusual ways to “see” it. Only recently have researchers been able to produce the extreme temperatures and pressures found inside our planet to understand how it is forming and evolving...

Potential new eye tumor treatment discovered
New research from a team including several Carnegie scientists demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma. The tumor is associated with mutations of a protein called Rb, or retinoblastoma protein. Dysfunctional Rb is also involved with other types of cancers, including lung, brain, breast and bone. Their work could result in a new therapeutic target for treating this rare form of cancer and potentially other cancers as well.

New Way to Monitor Faults May Help Predict Earthquakes
Scientists at the Carnegie Institution have found a way to monitor the strength of geologic faults deep in the Earth. This finding could prove to be a boon for earthquake prediction by pinpointing those faults that are likely to fail and produce earthquakes. Until now, scientists had no method for detecting changes in fault strength, which is not measureable at the Earth’s surface.

Old Star is “Missing Link” in Galactic Evolution
A newly discovered star outside the Milky Way has yielded important clues about the evolution of our galaxy. Located in the dwarf galaxy Sculptor some 280,000 light-years away, the star has a chemical make-up similar to the Milky Way’s oldest stars, supporting theories that our galaxy grew by absorbing dwarf galaxies and other galactic building blocks.

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.

Most-distant galaxy candidate found
A team of astronomers including Carnegie’s Daniel Kelson have set a new distance record for finding the farthest galaxy yet seen in the universe. By combining the power of NASA's Hubble Space Telescope, Spitzer Space Telescope, and one of nature's own natural "zoom lenses" in space, they found a galaxy whose light traveled 13.3 billion years to reach Earth.

Hurtling star possesses comet-like tail
Pasadena, CA - NASA's Galaxy Evolution Explorer has spotted an amazingly long comet-like tail behind a star streaking through space at extraordinary speeds.
The star, named Mira after the Latin word for "wonderful," has been a favorite of astronomers for about 400 years. It is a fast-moving older star, called a red giant, which sheds massive amounts of surface material.

Future Warming: Issues of Magnitude and Pace
Researchers reviewed the likelihood of continued changes to the terrestrial climate, including an analysis of a collection of 27 climate models. If emissions of heat-trapping gases continue along the recent trajectory, 21st century mean annual global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during 2046 to 2065 and 7.2 °F (4 °C) during 2081-2100.At this pace, it will probably be the most rapid large climate change in the last 65 million years.
