When geologists survey an area of land for the potential that gas or petroleum deposits could exist there, they must take into account the composition of rocks that lie below the surface. Previous research had suggested that compaction bands might act as barriers to the flow of oil or gas. Now, researchers led by José Andrade have analyzed X-ray images of Aztec sandstone and revealed that compaction bands are actually more permeable than earlier models indicated.

Caltech scientists have concocted a recipe for a thermoelectric material—one that converts heat energy into electricity—that might be able to operate off nothing more than the heat of a car's exhaust. In a paper published in Nature this month, G. Jeffrey Snyder and his colleagues reported on a compound that shows high efficiency in a temperature range of around 260 to 1160 degrees Fahrenheit. In other words, the heat escaping out your car's tailpipe could be used to help power its electrical components.

Those fences you'll soon see sprouting up around Jorgensen Laboratory are among the less classic signs of spring—and yet, they are very much a symbol of growth and rebirth. Now that the interior demolition of the building has been completed, with some 90 percent of the materials removed being reused or recycled, Jorgensen Lab's much-anticipated renovation is about to begin in earnest.

Average winter temperatures in northern Europe are at least 10 degrees Fahrenheit warmer than similar latitudes on the northeastern coast of the United States and the eastern coast of Canada. The same phenomenon happens over the Pacific, where winters on the northeastern coast of Asia are colder than in the Pacific Northwest. Researchers at Caltech have now found a mechanism that helps explain these chillier winters—and the culprit is warm water off the eastern coasts of these continents.

Thanks to a campaign led by a joint team of students from Caltech and the Southern California Institute of Architecture (SCI-Arc), the 2011 Solar Decathlon is back on the National Mall in Washington, D.C. The announcement made last week reverses an earlier decision by the U.S. Department of the Interior (DOI) to relocate the event.

Training the next generation of scientists is a critical component of the mission of Caltech's Resnick Institute. And although the institute is not yet two years old, it has already begun to fulfill that mission, thanks to the newly developed Resnick Fellowship program. The first two Resnick Fellows began their work in the fall of 2010; last week, the institute put out a call for applications for the next set of two-year awards.

About 450 million years ago, Earth suffered the second-largest mass extinction in its history—the Late Ordovician mass extinction, during which more than 75 percent of marine species died. Exactly what caused this tremendous loss in biodiversity remains a mystery, but now a team led by researchers at Caltech has discovered new details supporting the idea that the mass extinction was linked to a cooling climate.
