Thin Water Acts Like a Solid 138

Roland Piquepaille writes "What happens when you compress water in a nano-sized space? According to Georgia Tech physicists, water starts to behave like a solid. "The confined water film behaves like a solid in the vertical direction by forming layers parallel to the confining surface, while maintaining it's liquidity in the horizontal direction where it can flow out," said one of the researchers. "Water is a wonderful lubricant, but it flows too easily for many applications. At the one nanometer scale, water is a viscous fluid and could be a much better lubricant," added another one."

How Would You Deal With A Global Bandwidth Crisis? 478

lopy writes "First Google claimed the internet infrastructure won't scale to provide an acceptable user experience for online video. Then some networking experts predict that a flu pandemic would bring the internet to it's knees and lead to internet rationing. We used to think that bandwidth would always increase as needed, but what would happen if that isn't the case? How would you deal with a global bandwidth shortage? Would you be willing to voluntarily limit your internet usage if necessary? Could you live in a world without cheap and plentiful broadband internet access?"

Where Are Operating Systems Headed? 278

An anonymous reader writes "Dr. Dobb's Michael Swaine breaks down the question of where operating systems are headed. Among his teasers: Is Vista the last version of desktop Windows? (Counterintuitively, he says no.); Did Linux miss its window on the desktop? (Maybe.) And, most interestingly, are OSes at this point no longer necessary? He calls out the Symbian smartphone OS as something to keep an eye on, and reassures us that Hollywood-style OSes are not in our short-term future. Where do you weigh in on the future of operating systems? In ten years will we all be running applications via the internet?"
