Compare health insurance costs
Are instant insurance quotes as good as the ones you would get by sitting down in your neighborhood insurance agency? Yes, as long as you're truthful and accurate as you fill out your online application. If you lie about your tobacco use, hide that your hobby is hang gliding, or conceal a pre-existing illness, the insurance company may refuse to pay your claims. Insurance comparison websites work with many different insurance companies and they do not receive commissions for steering you toward one particular company or plan. So you can be assured that the quotes you receive are impartial and accurate.

Water within single-walled carbon nanotube poresWater and ice may not be among the first things that come to mind when you think about single-walled carbon nanotubes (SWCNTs), but a Japan-based research team hoping to get a clearer understanding of the phase behavior of confined water in the cylindrical pores of carbon nanotubes zeroed in on confined water's properties and made some surprising discoveries.

Understanding fatheringMost research studies that look at parenting focus on mothers. But fathers also exert direct, unique influences on their children, most likely because they engage with their children in different activities and have different styles of interaction than mothers�such as greater encouragement of risk taking and children's independence. Today, there is renewed attention to the role played by fathers, and there's new research on fathers and their........Go to the Science-blog (Added on 3/31/2011 7:01:28 AM)
Risky environments for children and their familiesood security is defined by access to sufficient, safe, and nutritious food to maintain a healthy and active life, as per the World Health Organization.

Relaxation leads to lower elasticityA number of materials, when observed over a sufficiently long period of time, show changes in their mechanical properties. The exact course of these developments depends on the underlying microscopic mechanisms. However, the microscopic structure and the complexity of the systems make direct observation extremely difficult.
That is why a team led by Professor Andreas Bausch from the Chair of Cellular Biophysics resorted to a model system........Go to the Science-blog (Added on 3/1/2011 9:17:14 PM)

Synthetic materials that behave like mollusk shellsNacre, usually known as mother-of-pearl, is the iridescent material lining a number of mollusk shells. It is part of a two-layer armor system that protects the animal from predators. The brittle outer layer of the shell absorbs the initial impact, but is prone to cracking. To prevent these cracks from catastrophically propagating through the shell to the animal itself, the nacreous layer is surprisingly strong and tough, with outstanding........Go to the Science-blog (Added on 2/2/2011 10:48:28 PM)

Globally Sustainable Fisheries PossibleThe bulk of the world's fisheries--including the kind of small-scale, often non-industrialized fisheries that millions of people depend on for food--could be sustained using community-based co-management. This is the conclusion of a study reported in this week's issue of the journal Nature.

Seeing the S-curve in everythingFrom economic trends, population growth, the spread of cancer, or the adoption of new technology, certain patterns inevitably seem to emerge. A new technology, for example, begins with slow acceptance, followed by explosive growth, only to level off before "hitting the wall".
When plotted on graph, this pattern of growth takes the shape of an "S".
While this S-curve has long been recognized by economists and scientists, a Duke University........Go to the Science-blog (Added on 7/20/2011 10:22:13 PM)

Recycling perlitePerlite, a processed volcanic mineral, is widely used as a component of soilless growing mixes. Lightweight, sterile, and easy to use, perlite is popular with greenhouse growers. But because salt and pathogen buildup can occur when perlite is reused, it must be replaced every year or two to minimize the risk of crop failure. The cost of disposing of old material and replacing it with new perlite can be significant and often prohibitive for........Go to the Science-blog (Added on 3/17/2011 11:01:50 PM)
Protein folding revealedMisfold an origami swan and the worst that happens is you wind up with an ugly paper duckling.

Iceland Volcano for High-Grade EnergyGeologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland met with a big surprise: underground lava, also called magma, flowed into the well at 2.1 kilometers (6,900 feet) depth.
