What Our Searches Tell Us About 2011: Bing Releases Most-Searched Terms of the Year

*From royal weddings and rising pop superstars to concerns for human tragedy and the global economy, Bing’s most-searched terms of the year capture America’s mood in 2011.*

REDMOND, Wash. – Nov. 28, 2011 – What do pop superstar Justin Bieber, new duchess Kate Middleton, and consumer electronics king Xbox have in common? No, they’re not all part of a wildly anticipated Hollywood sci-fi flick (at least not yet); they were some of the most popular search terms typed this past year on Bing. (more…)

New Study Finds That Even the Cleanest Wastewater Contains ‘Super Bacteria’

*University of Minnesota research suggests that wastewater treated with standard technologies contains far greater quantities*

MINNEAPOLIS / ST. PAUL — A new University of Minnesota study reveals that the release of treated municipal wastewater – even wastewater treated by the highest-quality treatment technology – can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as “superbacteria,” in surface waters.

The study also suggests that wastewater treated using standard technologies probably contains far greater quantities of antibiotic-resistant genes, but this likely goes unnoticed because background levels of bacteria are normally much higher than in the water studied in this research. (more…)

Earth’s Core Deprived of Oxygen

Washington, D.C. — The composition of the Earth’s core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well. Oxygen is the most abundant element in the planet, so it is not unreasonable to expect oxygen might be one of the dominant “light elements” in the core. However, new research from a team including Carnegie’s Yingwei Fei shows that oxygen does not have a major presence in the outer core. This has major implications for our understanding of the period when the Earth formed through the accretion of dust and clumps of matter. Their work is published Nov. 24 in Nature. (more…)

Tuning out: How Brains Benefit From Meditation

Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study by Yale researchers.

Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study published the week of Nov. 21 in the Proceedings of the National Academy of Sciences. Understanding how meditation works will aid investigation into a host of diseases, he said. (more…)

On the Road to Plasmonics with Silver Polyhedral Nanocrystals

*Berkeley Lab Researchers Find Simpler Approach to Making Plasmonic Materials*

The question of how many polyhedral nanocrystals of silver can be packed into millimeter-sized supercrystals may not be burning on many lips but the answer holds importance for one of today’s hottest new high-tech fields – plasmonics! Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) may have opened the door to a simpler approach for the fabrication of plasmonic materials by inducing polyhedral-shaped silver nanocrystals to self-assemble into three-dimensional supercrystals of the highest possible density.
