Supercomputers give universities a competitive edge, researchers find
Researchers have long believed that supercomputers give universities a competitive edge in scientific research, but now they have some hard data showing it's true. A Clemson University team found that universities with locally available supercomputers were more efficient in producing research in critical fields than universities that lacked supercomputers.

Carnegie Mellon's snake robots learn to turn by following the lead of real sidewinders
Researchers at Carnegie Mellon University who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device. Working with colleagues at the Georgia Institute of Technology and Zoo Atlanta, they have analyzed the motions of sidewinders and tested their observations on CMU's snake robots.

CMU study finds location sharing by apps prompts privacy action
Many smartphone users know that free apps sometimes share private information with third parties, but few, if any, are aware of how frequently this occurs. An experiment at Carnegie Mellon University shows that when people learn exactly how many times these apps share that information they rapidly act to limit further sharing.

Study: Western forests decimated by pine beetles not more likely to burn
Western US forests killed by the mountain pine beetle epidemic are no more at risk to burn than healthy Western forests, according to new findings by the University of Colorado Boulder that fly in the face of both public perception and policy.

A stiff new layer in Earth's mantle
By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth's sinking tectonic plates sometimes stall and thicken 930 miles underground. The findings also may explain some deep earthquakes, hint that Earth's interior is hotter than believed, and suggest why magmas feeding midocean-ridge volcanoes differ chemically from magmas supplying hotpot island volcanoes.

Comparing the genomes of the leprosy bacteria
EPFL scientists have compared for the first time the genomes of the two bacteria species that cause leprosy. The study shows how the two species evolved from a common ancestor 13.9 million years ago, and offers new insights into their biology that could lead to new treatments.

Landmark study proves that magnets can control heat and sound
Researchers at the Ohio State University have discovered how to control heat with a magnetic field. In the March 23 issue of the journal Nature Materials, they describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. The study is the first ever to prove that acoustic phonons -- the elemental particles that transmit both heat and sound -- have magnetic properties.

A new study published in the Journal of Hydrology led by WHRC scientist Prajjwal Panday found that large protected areas in the Xingu River Basin have helped shield this Amazonian watershed from the effects observed in its less-protected neighbor, the Araguaia-Tocantins.

Levee detonations reduced 2011 flood risk on Mississippi River, UCI-led study finds
A controversial decision in 2011 to blow up Mississippi River levees reduced the risk of flooding in a city upstream, lowering the height of the rain-swollen river just before it reached its peak, according to a newly published computer modeling analysis led by UC Irvine scientists.

Squid enrich their DNA 'blueprint' through prolific RNA editing
RNA editing of genomic information was thought to be sparingly used, based on a limited number of studies in mammals and flies. But recently, MBL Whitman Investigator Joshua Rosenthal and colleagues discovered the most prolific usage yet of RNA editing in the common squid, Doryteuthis pealeii, a behaviorally sophisticated marine organism that has long been prized for studies of the nervous system.

HAWC Observatory to study universe's most energetic phenomena
The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory is the newest tool available to visualize the universe's most explosive events and learn more about the nature of high-energy radiation. Construction is now complete on HAWC's 300th and final detector tank, and the observatory will soon begin collecting data at full capacity. This milestone will be marked with an inaugural event at the observatory on March 19-20, 2015.

World Heritage Sites risk collapse without stronger local management
Without better local management, the world's most iconic ecosystems are at risk of collapse under climate change, say researchers in Science. Protecting places of global environmental importance such as the Great Barrier Reef and the Amazon rainforest from climate change will require reducing the other pressures they face, for example overfishing, fertilizer pollution or land clearing.

An improved method for coating gold nanorods
Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell. Gold nanorods are being investigated for use in a wide variety of biomedical applications, and this advance paves the way for more stable gold nanorods and for chemically functionalizing the surface of the shells.
