Plants’ fungi allies may not help store climate change’s extra carbon

Fungi found in plants may not be the answer to mitigating climate change by storing additional carbon in soils as some previously thought, according to an international team of plant biologists.

Antarctic ice sheet quakes shed light on ice movement and earthquakes

Analysis of small, repeating earthquakes in an Antarctic ice sheet may not only lead to an understanding of glacial movement, but may also shed light on stick slip earthquakes like those on the San Andreas fault or in Haiti, according to Penn State geoscientists.

Tibetan Plateau may be older than previously thought

The growth of high topography on the Tibetan Plateau in Sichuan, China, began much earlier than previously thought, according to an international team of geologists who looked at mountain ranges along the eastern edge of the plateau.

Penn State scientists help construct largest 3-D map of the universe

The Sloan Digital Sky Survey III (SDSS-III), an international collaboration that includes Penn State astronomers, has produced the largest-ever three-dimensional map of massive galaxies and distant black holes.

Polar bear evolution tracked climate change, new DNA study suggests

An analysis of newly sequenced polar bear genomes is providing important clues about the species' evolution, suggesting that climate change and genetic exchange with brown bears helped create the polar bear as we know it today.
