Rare supernova discovery ushers in new era for cosmology
With from an automated supernova-hunting pipeline based at NERSC, astronomers have captured multiple images of a gravitationally lensed Type 1a supernova. This detection is currently the only one of its kind, but astronomers believe that if they can find more they may be able to measure the rate of the Universe's expansion within four percent accuracy. Fortunately, two Berkeley Lab researchers do have a method for identifying more of these events using existing wide-field surveys.

Study on impact of climate change on snowpack loss in Western US
An international team of scientists, including one from Lawrence Livermore National Laboratory, has found that up to 20 percent loss in the annual maximum amount of water contained in the Western United States' mountain snowpack in the last three decades is due to human influences.

International Conference on Mathematics & Computational Methods to Nuclear Science & Engineering
Predictive power
The Consortium for Advanced Simulation of Light Water Reactors carried out the largest time-dependent simulation of a nuclear reactor ever to support Tennessee Valley Authority and Westinghouse Electric Company during the startup of Watts Bar Unit 2, the first new US nuclear reactor in 20 years. The simulation was carried out primarily on Oak Ridge Leadership Computing Facility resources.

Better living through pressure: Functional nanomaterials made easy
Using pressure instead of chemicals, nanoparticles have been fabricated into nanowire arrays similar to those that underlie touch-screens for phones, computers, TVs, and sensors. The pressure process takes nanoseconds instead of the hours required by industry's current chemical means.

Tweaking a molecule's structure can send it down a different path to crystallization
Silky chocolate, a better medical drug, or solar panels all require the same thing: just the right crystals making up the material. Now, scientists trying to understand the paths crystals take as they form have been able to influence that path by modifying the starting ingredient.

Advantage: Water
When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the slightest advantage, like the score in a highly competitive tennis game.

On-the-range detection technology could corral bovine TB
A research breakthrough allowing the first direct, empirical, blood-based, cow-side test for diagnosing bovine tuberculosis (TB) could spare ranchers and the agriculture industry from costly quarantines and the mass slaughter of animals infected with this easily spread disease.

Did you catch that? Robot's speed of light communication could protect you from danger
If you were monitoring a security camera and saw someone set down a backpack and walk away, you might pay special attention -- especially if you had been alerted to watch that particular person. According to Cornell University researchers, this might be a job robots could do better than humans, by communicating at the speed of light and sharing images.

Forget sponges: The earliest animals were marine jellies
One of the longest-running controversies in evolutionary biology has been, 'What was the oldest branch of the animal family tree?' Was it the sponges, as had long been thought, or was it the delicate marine predators called comb jellies? A powerful new method has been devised to settle contentious phylogenetic tree-of-life issues like this and it comes down squarely on the side of comb jellies.
