Near-roadway air pollution a major contributor to asthma in Los Angeles County, USC research finds

LOS ANGELES – Research conducted at the University of Southern California (USC) indicates that at least 8 percent of the more than 300,000 cases of childhood asthma in Los Angeles County can be attributed to traffic-related pollution at homes within 75 meters (a little less than 250 feet) of a busy roadway.

Constraining world trade doesn't help the climate

CO2 tariffs would probably have only a small impact on global emissions. Why? There are a lot of knobs that explain the pronounced imbalances between emission importers and exporters and the US trade deficit is one of them. So interventions in world trade, like CO2 tariffs, would only have a small impact on global emissions.

Stratosphere targets deep sea to shape climate

SALT LAKE CITY, Sept. 23, 2012 – A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate.

"We found evidence that what happens in the stratosphere matters for the ocean circulation and therefore for climate," says Thomas Reichler, senior author of the study published online Sunday, Sept. 23 in the journal Nature Geoscience.

Naked mole-rats may hold clues to pain relief

Naked mole-rats evolved to thrive in an acidic environment that other mammals, including humans, would find intolerable. Researchers at the University of Illinois at Chicago report new findings as to how these rodents have adapted to this environment.

The study was published online this week on PLOS ONE.

23 nuclear power plants are in tsunami risk areas

The tsunami in Japan in March 2011 unleashed a series of negligence related with the resulting nuclear disaster. A scientific study headed by Spanish researchers has for the first time identified those atomic power plants that are more prone to suffering the effects of a tsunami. In total, 23 plants are in dangerous areas, including Fukushima I, with 74 reactors located in the east and southeast of Asia.

Physicists reveal striking similarities in sporting performance

Finding the similarities between volleyball and snooker may seem quite tricky. However, a group of physicists have found that the spread of scores, otherwise known as distribution, across their ranking systems are almost identical.

They've also shown that this is the same for almost all sports, whether their ranking systems are based on points or the earnings of each individual or team.

Data link project provides new insight about the US R&D activities of multinational companies

Findings from the Research and Development Data Link Project showed that both parent companies of U.S. multinational companies and U.S. affiliates of foreign multinational companies devoted about three-fourths of their R&D expenditures to development activities in 2007.

This newly developed information is from the Research and Development Data Link Project--a joint project of the National Science Foundation, U.S. Census Bureau and Bureau of Economic Analysis.

Battles between steroid receptors to regulate fat accumulation

HOUSTON -- (Sept. 21, 2012) – The androgen receptor in human cells inhibits fat accumulation, but its activity can be sabotaged by glucocorticoids, steroids that regulate fat deposition and are known drivers of obesity and insulin resistance, said researchers led by those at Baylor College of Medicine (www.bcm.edu) in a report in the journal Chemistry & Biology (https://www.cell.com/chemistry-biology/home).

Novel plastic-and-papyrus restoration project

Plans are being implemented to create plastic floating islands containing papyrus plants to help protect the ecosystems of a renowned lake in the Rift Valley, Kenya.

The German REWE Group is funding a papyrus restoration partnership between UK-owned tea producer and flower grower Finlays and Dr David Harper, a Senior Lecturer at the University of Leicester, which aims to recreate the water-cleansing services of papyrus as artificial floating islands.

Children in Switzerland are using mobile phones to go online

On average, children in Switzerland are 9 years old when they use the internet for the first time. They spend on average 64 minutes per day online, which is substantially less than the European average (88 minutes). These are the results of a new study carried out by the Institut für Publizistikwissenschaft und Medienforschung (Institute of Mass Communication and Media Research) at the University of Zurich. The survey was conducted in the German-speaking and western part of Switzerland with 1,000 children and young people as well as one of their parents in each case.

Computer simulations for multiscale systems can be faster, better, more reliable

EUGENE, Ore. -- (Sept. 20, 2012) -- University of Oregon scientists have found a way to correctly reproduce not only the structure but also important thermodynamic quantities such as pressure and compressibility of a large, multiscale system at variable levels of molecular coarse-graining.

The method is a mathematically driven predictive modeling of a real system, built on liquid state theory, and utilizing powerful computing resources. The team's theory appears in the Sept. 21 issue of the journal Physical Review Letters.

Climate scientists put predictions to the test

Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found.

Study shows how consumers shift expectations and goals

NEW YORK - September 19, 2012 - Sally and Harry are about to invest in their company's 401(k) plan. Sally chooses the best performing mutual fund, which has high risks but boasts a 25 percent year-to-date return. Harry, after considering the tradeoffs between risks and rewards, opts for a lower performing fund with an 8 percent year-to-date return. When they receive their next quarterly performance reports, both Sally and Harry discover that their funds have met their initial expectations. Are they satisfied? If not, why? And how could their levels of satisfaction be improved?

Using a laser to 'see' the smallest world

(Santa Barbara, Calif.) –– A multi-university team has employed a high-powered laser based at UC Santa Barbara to dramatically improve one of the tools scientists use to study the world at the atomic level. The team used their amped-up electron paramagnetic resonance (EPR) spectrometer to study the electron spin of free radicals and nitrogen atoms trapped inside a diamond.

The improvement will pull back the veil that shrouds the molecular world, allowing scientists to study tiny molecules at a high resolution.
