Second Life, a virtual world created in 2003, currently boasts more than 12 million users worldwide who go there for everything from college recruiting to shopping. Now, Penn State researchers are investigating how virtual teams can better solve real world problems by collaborating in Second Life.

COLLEGE STATION, TX –- A new generation has come of age since the first celebration of Earth Day in 1970. For this and future generations, environmental awareness is an important and burgeoning point of reference.
SAN MARCOS, TX — The next time you see students playing an energized game of touch football or studying in the sunshine on a college quadrangle, consider this: campus green spaces can help students feel better about life and improve learning.
Researchers at the Georgia Institute of Technology have developed a computer program that trains itself to predict genes in the DNA sequences of fungi.
Fungi – which range from yeast to mushrooms – are important for industry and human health, so understanding the recently sequenced fungal genomes can help in developing and producing critical pharmaceuticals. Gene prediction can also help to identify potential targets for therapeutic intervention and vaccination against pathogenic fungi.
A protein required for the earliest steps in embryonic development also plays a key role in solidifying fear memories in the brains of adult animals, scientists have revealed. An apparent "hub" for changes in the connections between brain cells, beta-catenin could be a potential target for drugs to enhance or interfere with memory formation.
The results are published online this week and appear in the October issue of Nature Neuroscience.
COLUMBIA, Mo. -- Gold nanoparticles are everywhere. They are used in cancer treatments, automobile sensors, cell phones, blood sugar monitors and hydrogen gas production. However, until recently, scientists couldn't create the nanoparticles without producing synthetic chemicals that had negative impacts on the environment. A new method, created by a University of Missouri research team, not only eliminates any negative environmental impact, but also has resulted in national and international recognition for the lead scientist.
For decades now, cigarette makers have marketed so-called light cigarettes — which contain less nicotine than regular smokes — with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain.
Scientists at Yale School of Medicine have found that two-year-olds with autism looked significantly more at the mouths of others, and less at their eyes, than typically developing toddlers. This abnormality predicts the level of disability, according to study results published in the Archives of General Psychiatry.
PHILADELPHIA –- With less than six weeks until the general election, a University of Pennsylvania study analyzing the relative optimism of the 2008 presidential and vice presidential candidates has found Barack Obama and John McCain to be equally optimistic and Sarah Palin slightly more optimistic than Joseph Biden.
The law known as No Child Left Behind (NCLB), enacted in 2002, set an ambitious goal: that across the nation, every state would test students annually in reading and math, and that the number of students scoring at the level of "proficient" or higher would rise each year, until all students reached proficiency in the year 2014.
Most residents in fire-prone communities surrounded by the San Bernardino National Forest have taken steps to protect their homes from wildland fires, according to a U.S. Forest Service study completed this summer.
Understanding biology at the systems level is difficult, especially when studying complex specimens like tissue slices or communities of organisms in a biofilm. Scientists must be able to identify, quantify and locate the molecules present in the samples.
At Georgia Tech, researchers from the Colleges of Sciences and Engineering have joined forces to create the Center for Bio-Imaging Mass Spectrometry (BIMS), which aims to tackle these types of challenges.
Auctions are an old and widely used method for allocating goods that have become increasingly common with the advent of internet auctions sites such as Ebay. Previous economic research has shown that in an auction people tend to bid "too high," or overbid, given the value of the item for sale. By combining brain imaging techniques with behavioral economic research, neuroscientists and economists at New York University were able to provide new insight into this tendency to overbid.
You might think that the farthest distance at which you can hold a book and still read it quickly is determined by the size of the letters. However, New York University neuroscientists have concluded that it's the spacing between letters, not their size, that matters. In general, objects, such as letters, can be recognized only if they are separated by enough space, the "critical spacing." Objects closer than that spacing are "crowded" and cannot be identified.
RIVERSIDE, Calif. – How well students and schools – from kindergarten through high school – succeed in mastering a curriculum that includes English Language Arts (ELA), mathematics, and the social and natural sciences, strongly influences how well the students fare in higher education.
