Web users who stick to one or two search engines and learn those well will have better results for their queries than users who try the same query or various engines, a Penn State researcher says.
“There are no wholesale rules about structuring a query that will work on multiple search engines,” said Bernard J. Jansen, assistant professor of information sciences and technology (IST). “And what works on one engine, such as narrowing a query, can have the opposite effect on other search engine
With the flexibility to check e-mail at home, get the kids ready for school, call your boss on the way to work, and text message your next appointment, the nature of work has changed. However, contrary to popular opinion, people who integrate their work and families are not always happier, Michigan State University researchers say.
Instead, Ellen Kossek, an MSU professor of Labor and Industrial Relations, found that people who establish boundaries between work and family are actually more
WWF Italia is monitoring the urbanization of the Italian coast to catch overdeveloped “hot spots”, courtesy of an ESA programme to develop new applications-driven services with space data.
WWF Italia has been working with ESA as part of the Agencys Urban Expansion (UrbEx) project to provide a novel information service that monitors the loss of natural areas from urban development. The projects objective was to demonstrate the capability to monitor urban growth using Earth observa
Hurricanes cannot form near the equator, or so meteorology textbooks maintain. But a storm named Typhoon Vamei upended scientists thinking when it swirled above the equator in the South China Sea near Singapore on December 27, 2001. It formed so close to the equator that its winds howled in both hemispheres.
New research funded by the National Science Foundation (NSF) and the U.S. Navys Office of Naval Research reveals the unusual mechanism for the birth of such a storm.
Center for Behavioral Neuroscience (CBN) researchers have demonstrated that genetically identical mice placed in different environments both pre- and post-natally differ dramatically as adults in their stress responses and learning abilities. The finding, reported in the May issue of Nature Neuroscience, suggests that pre- and post-natal maternal environments, when taken together, play a strong role in determining the stress profile and cognitive development of genetically identical mice.

An interdisciplinary team of researchers from the Hebrew University of Jerusalem, Stanford University and Tel Aviv University has developed the first computational method that can identify clusters of genes responsible for controlling processes within a cell, when those clusters become active, and, most importantly, how the clusters are regulated.
In a paper published online May 12 by Nature Genetics, the researchers report that their method revealed several previously unknown control, or r
