A new statistical model predicts that by 2100 the number of people older than 85 worldwide will increase more than previously estimated, and there will be fewer working-age adults to support them than previously expected. (more…)
Most computers are not slow out of the box, with use and new programs installed a computer can slow down significantly. A slow running computer can be a nightmare, and really cut productivity. Not only that, but it can be extremely aggravating and time consuming to fix. It is actually very simple to speed up a slow running computer with just a simple few steps. Here are 5 easy steps to make a computer run faster.
Disable Startup Items
Many programs automatically startup even though it may not be necessary. By clicking start, run, and typing msconfig, then going to the startup tab. You can see which programs are automatically starting up when the computer is turned on. It would be prudent to disable anything that is not necessary to startup with the computer. Any programs that do not startup automatically can be opened manually later if needed. This frees up memory for more essential activities. (more…)
Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? (more…)
In the world of proteins, form defines function. Based on interactions between their constituent amino acids, proteins form specific conformations, folding and twisting into distinct, chemically directed shapes. The resulting structure dictates the proteins’ actions; thus accurate modeling of structure is vital to understanding functionality.
Peptoids, the synthetic cousins of proteins, follow similar design rules. Less vulnerable to chemical or metabolic breakdown than proteins, peptoids are promising for diagnostics, pharmaceuticals, and as a platform to build bioinspired nanomaterials, as scientists can build and manipulate peptoids with great precision. But to design peptoids for a specific function, scientists need to first untangle the complex relationship between a peptoid’s composition and its function-defining folded structure. (more…)
Washington, D.C. – For years, scientists have debated how big a role elephants play in toppling trees in South African savannas. Tree loss is a natural process, but it is increasing in some regions, with cascading effects on the habitat for many other species. Using high resolution 3-D mapping, Carnegie scientists have for the first time quantitatively determined tree losses across savannas of Kruger National Park. They found that elephants are the primary agents—their browsing habits knock trees over at a rate averaging 6 times higher than in areas inaccessible to them. The research also found that elephants prefer toppling trees in the 16-to-30 foot (5-8 m) range, with annual losses of up to 20% in these height classes. The findings, published in Ecology Letters, bolster our understanding of elephant conservation needs and their impacts, and the results could help to improve savanna management practices.
“Previous field studies gave us important clues that elephants are a key driver of tree losses, but our airborne 3-D mapping approach was the only way to fully understand the impacts of elephants across a wide range of environmental conditions found in savannas,” commented lead author Greg Asner of Carnegie’s Department of Global Ecology. “Our maps show that elephants clearly toppled medium-sized trees, creating an “elephant trap” for the vegetation. These elephant-driven tree losses have a ripple effect across the ecosystem, including how much carbon is sequestered from the atmosphere.” (more…)
American megachurches use stagecraft, sensory pageantry, charismatic leadership and an upbeat, unchallenging vision of Christianity to provide their congregants with a powerful emotional religious experience, according to research from the University of Washington.
“The megachurches movement is one of the leading indicators of how American Christians exercise their faith these days, so therefore they should be understood,” said James Wellman, associate professor of American religion at the University of Washington. “And our study shows they’re doing a pretty effective job for their members, based on self-reports, contrary to public opinion that tends to pass them off as a type of consumerist religion. In fact, their members speak eloquently of their spiritual growth.” (more…)
Michael Dula recently began his appointment as chief technology officer for the Yale University Library, which is one of the largest university libraries in North America. In this newly created role, he will develop a technology strategy for the University’s 18 different libraries, which house over 12.5 million volumes.
Prior to coming to Yale, Dula worked at Pepperdine University, where he began as a consultant. In 2006, he accepted a full-time position at Pepperdine as director of digital initiatives for the university’s libraries. In addition to managing central library technology systems, he was actively engaged in implementing new tools for research and learning, including digital content collections, scholarly publishing, podcasting, and social computing models.

Berkeley Lab Researchers Help Develop a Computer Model That Identifies the Best Molecular Candidates
A computer model that can identify the best molecular candidates for removing carbon dioxide, molecular nitrogen and other greenhouse gases from power plant flues has been developed by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California (UC) Berkeley and the University of Minnesota.
