comScore MMX Ranks Top 50 U.S. Web Properties for August 2012

RESTON, VA, September 12, 2012 – comScore, Inc., a leader in measuring the digital world, today released its monthly analysis of U.S. web activity at the top online properties for August 2012 based on data from the comScore MMX service.

With the release of August 2012 U.S. MMX data, comScore introduced three important methodological enhancements to our estimates that will affect data on a go-forward basis. The first enhancement is the incorporation of updated demographic universe estimates based on data from the 2010 U.S. census, which provides an improved accounting of the percentage of the population falling into each demographic segment. The second enhancement was an improvement in comScore’s enumeration survey methodology to better represent persons in cell-phone only households. The third and final enhancement is a new technique to account for cookie rejection in Safari browsers, for sites measured via comScore’s Unified Digital Measurement (UDM) methodology.. (more…)

Beacons Light up Stem Cell Transformation

Science

In a new study, Brown University researchers demonstrate a new tool for visually tracking in real-time the transformation of a living population of stem cells into cells of a specific tissue. The “molecular beacons,” which could advance tissue engineering research, light up when certain genes are expressed and don’t interfere with the development or operation of the stem cells.

PROVIDENCE, R.I. [Brown University] — A novel set of custom-designed “molecular beacons” allows scientists to monitor gene expression in living populations of stem cells as they turn into a specific tissue in real-time. The technology, which Brown University researchers describe in a new study, provides tissue engineers with a potentially powerful tool to discover what it may take to make stem cells transform into desired tissue cells more often and more quickly. That’s a key goal in improving regenerative medicine treatments. (more…)

Wind Power’s Potential

Environment

UD-Stanford team calculates maximum global energy potential from wind

Wind turbines could power half the world’s future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.

The researchers arrived at the determination by calculating the maximum theoretical potential of wind power worldwide, taking into account the effects that numerous wind turbines would have on surface temperatures, water vapor, atmospheric circulations and other climatic considerations.

“Wind power is very safe from the climate point of view,” said Cristina Archer, associate professor of geography and physical ocean science and engineering at UD. (more…)

UA Professor Uses Aerospace Materials to Build Endless Green Pipeline

Science

Carbon fiber fabric and lightweight honeycomb materials, plus a mobile manufacturing platform, make infinite pipeline technology cheaper and greener while boosting local economies.

Mo Ehsani, professor emeritus of civil engineering at the University of Arizona, has designed a new, lightweight underground pipe he says could transform the pipeline construction industry. (more…)

September 11 and The Cost of War

Politics

The Costs of War project is assessing the total cost of the conflicts in Iraq and Afghanistan in the wake of the 9-11 attacks. Findings thus far put the cost at more than 300,000 lives and $4 trillion. The project’s findings are continually updated. (more…)

Crows React to Threats in Human-like Way

Nature

Cross a crow and it’ll remember you for years.

Crows and humans share the ability to recognize faces and associate them with negative, as well as positive, feelings. The way the brain activates during that process is something the two species also appear to share, according to new research being published this week. (more…)

Employees at ‘Green’ Companies are Significantly more Productive, Study Finds

Economy

Bucking the idea that environmentalism hurts economic performance, a new UCLA-led study has found that companies that voluntarily adopt international “green” practices and standards have employees who are 16 percent more productive than the average. (more…)

Face to Face

Science

Research finds infants classify faces by gender, race

Long before babies can talk — even before they can sit up on their own — they are mentally forming categories for objects and animals in a way that, for example, sets apart squares from triangles and cats from dogs, psychologists say.

Now, research conducted by the University of Delaware’s Paul Quinn, professor of psychology, and others indicates that babies as young as 3 months are also classifying faces by race and gender, showing a visual preference for the category they see most often in their daily lives, and that by 9 months they have difficulty recognizing the faces of people from less-familiar races.
