New understanding of Earth’s mantle beneath the Pacific Ocean
Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the lithosphere and underlying asthenosphere. Understanding this boundary is central to our knowledge of plate tectonics and thus the formation and evolution of our planet as we know it today. A new technique for observing this transition, particularly in the portion of Earth’s mantle that lies beneath the Pacific Ocean basin, has led Carnegie and NASA Goddard scientist Nick Schmerr to new insight on the origins of the lithosphere and asthenosphere.

Exoplanet Formation Surprise
A team of researchers has discovered evidence that an extrasolar planet may be forming quite far from its star—about twice the distance Pluto is from our Sun. The planet lies inside a dusty, gaseous disk around a small red dwarf TW Hydrae, which is only about 55% of the mass of the Sun. The discovery adds to the ever-increasing variety of planetary systems in the Milky Way.

Rain forest protection works in Peru
Stanford, CA—A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. Scientists at the Carnegie Institution’s Department of Global Ecology led an international effort to analyze seven years of high-resolution satellite data covering most (79%) of the Peruvian Amazon for their findings. The work is published in the Science Express.

Major Changes Needed For Coral Reef Survival
To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie’s Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be engulfed in inhospitable ocean chemistry conditions by the end of the century if civilization continues along its current emissions trajectory.

Honing in on supernova origins
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the explosions happen. New research from a team led by Harvard University and including Carnegie’s Josh Simon, Chris Burns, Nidia Morrell, and Mark Phillips examined 23 Type Ia supernovae and helped identify the formation process for at least some of them.

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...

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.

Carnegie’s Timothy Strobel to Receive Jamieson Award
Carnegie’s Geophysical Laboratory’s newest staff member, Timothy Strobel, will be given the prestigious Jamieson Award on September 26, 2011, from the International Association for the Advancement of High Pressure Science and Technology in Mumbai, India. The Jamieson Award is given to a scientist who has just completed outstanding PhD thesis research or to an exceptional postdoctoral researcher. Strobel’s research focuses on developing new hydrogen-based materials to meet our country’s energy challenges.

Geoengineering and global food supply
Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter. There are concerns that a continuation of these trends could have catastrophic effects, including crop failures in the heat-stressed tropics. This has led some to explore drastic ideas for combating global warming, including the idea of trying to counteract it by reflecting sunlight away from the Earth. However, it has been suggested that reflecting sunlight away from the Earth might itself threaten the food supply of billions of people. New research led by Carnegie’s Julia Pongratz examines the potential effects that geoengineering the climate could have on global food production and concludes that sunshade geoengineering would be more likely to improve rather than threaten food security.

Plant research funding crucial for the future
The scientific community needs to make a 10-year, $100 billion investment in food and energy security, says Carnegie’s Wolf Frommer and Tom Brutnell of the Donald Danforth Plant Science Center in an opinion piece published in the June issue of The Scientist. They say the importance of addressing these concerns in light of a rapidly growing global population is on par with President John Kennedy’s promise to put man on the moon—a project that took a decade and cost $24 billion.

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.

Disappearing and reappearing superconductivity surprises scientists
Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials at low temperatures, or can be induced under chemical and high external pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission. New work demonstrates unexpected superconductivity in a type of compounds called iron selenium chalcogenides.
