COLLEGE PARK, Md. – Newly released U.S. Census figures show the poverty rate essentially leveled in 2011 – beating the expectations of many experts who had predicted a fifth straight increase, says Professor Douglas Besharov, an expert on poverty and welfare at the University of Maryland School of Public Policy.

It’s morning, deep in the Amazon jungle. In the still air innumerable leaves glisten with moisture, and fog drifts through the trees. As the sun rises, clouds appear and float across the forest canopy … but where do they come from? Water vapor needs soluble particles to condense on. Airborne particles are the seeds of liquid droplets in fog, mist, and clouds.
To learn how aerosol particles form in the Amazon, Mary Gilles of the Chemical Sciences Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and David Kilcoyne of the Lab’s Advanced Light Source (ALS) worked with Christopher Pöhlker of Germany’s Max Planck Institute for Chemistry (MPIC) as part of an international team of scientists led by MPIC’s Meinrat Andreae and Ulrich Pöschl. They analyzed samples of naturally formed aerosols collected above the forest floor, deep in the rainforest. (more…)
Gaining more insight into predicting how genes affect physical or behavioral traits by charting the genotype-phenotype map holds promise to speed discoveries in personalized medicine. But figuring out exactly how genes interact has left parts of the map invisible. (more…)
Fortune 100 Clients Tout Returns on Social Investments
ARMONK, N.Y. – 12 Sep 2012: IBM today unveiled new software and services that bring the power of big data analytics into the hands of today’s social savvy workforce anytime, anywhere. Now, organizations can apply analytics to their social business initiatives, allowing them to gain actionable insight on information generated on networks and put it to work in real-time. (more…)
EAST LANSING, Mich. — People who commit cyber-attacks against the government also tend to download music illegally and participate in physical protests. Surprisingly, however, they don’t appear to be acting out of some sense of national pride or patriotism.
Those are some of the findings to emerge from a Michigan State University study that for the first time begins to paint a profile of “civilian cyber-warriors,” or people who engage in attacks against domestic or foreign governments without support from military or government agencies. Cybercrimes pose a huge societal risk and have become a hot issue globally, yet little is known about the mindset behind them. (more…)
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…)
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…)
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…)
