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."

Londovir asks: "Recently, our school board made the decision to block Wikipedia from our school district's WAN system. This was a complete block — there aren't even provisions in place for teachers or administrators to input a password to bypass the restriction. The reason given was that Wikipedia (being user created and edited) did not represent a credible or reliable source of information for schools. Should we block sites such as Wikipedia because students may be exposed to misinformation, or should we encourage sites such as Wikipedia as an outlet for students to investigate and determine the validity of the information?"

Roland Piquepaille writes "The launch of the Orbital Express mission, with its two satellites ASTRO and NextSat, the first one servicing the other, was widely covered a month ago. But what is happening in space now? In 'Robotic satellite servicer rehearsal underway in orbit,' Spaceflight Now reports about the progress done. A week ago, the two satellites were able to link to each other to operate the first transfer of hydrazine fuel from ASTRO's propellant tanks into NextSat. This weekend, ASTRO's ten-foot-long robotic arm is going to be used to move objects to NextSat. But what does it mean for international satellite operators when they need help with their space birds? Will they use a system designed for U.S.'s DARPA? "

Roland Piquepaille writes to let us know about research into producing palpable maps for the blind. Scientific American has the story of Greek researchers who produce 3D "haptic" maps that "use force fields to represent walls and roads so the visually impaired can better understand the layout of buildings and cities." Two separate systems produce haptic output from standard video and from 2D maps. The systems have been tested on a small number of users. Currently the devices that interpret the "force fields" for sight-impaired users are not portable, and so the systems are most appropriate for doing research before, e.g., visiting a new city.

Roland Piquepaille writes "Researchers from Illinois and Florida are developing a networking system which will create virtual representations of real people to improve our knowledge. They will use artificial intelligence and natural language processing software to enable us to interact with these avatars. The goal of the project, sponsored by the National Science Foundation (NSF), is to give us the possibility to interact with these virtual representations as if they were the actual person, complete with the ability to understand and answer questions. We should see the results at the beginning of 2008 — if the researchers succeed."

writertype writes "Although Blackboard is used to communicate between students and professors at virtually all of PC Magazine/Princeton Review's top 20 wired colleges, when run under a Vista environment users can see glitches. Moreover, IT departments told PC Mag that if Blackboard is used with Vista plus IE7, students can't communicate via the software. When asked why, Microsoft ... waffled. Blackboard says they'll have a fix in place by summer. Meanwhile, are there any other common college apps that Vista fails to work with?"

TunesBoy writes "Only a couple of days after being shipped, the Apple TV is already being modified in a variety of ways. A thread at Something Awful discusses installing VLC, and a dedicated site, AppleTVHacks.net, has appeared and is cataloging hacks including a hard-drive upgrade tutorial. Did Apple intend for the Apple TV to be so easy to upgrade and hack?"

Stu writes "'A world without net neutrality is one devoid of intellectual development' said Sir Tim Berners Lee in a presentation to congress last week. Well, now there's a computer model that uses game theory to back that forecast up. Developed at the University of Florida, the model shows that everyone loses if the IPs get their way — even, eventually, the IPs."

coondoggie sends us a NetworkWorld story on the prospects for Apple gaining market share in the corporation. A number of factors are helping to catch the eye of those responsible for upgrading desktops and servers, the article claims: "Apple's shift to the Intel architecture; the inclusion of infrastructure and interoperability hooks, such as directory services, in the Mac OS X Server; dual-boot capabilities; clustering and storage technology; third-party virtualization software; and comparison shopping, which is being fostered by migration costs and hardware overhauls associated with Microsoft's Vista." On this last point, one network admin is quoted: "The changes in Vista are significant enough that we think we can absorb the change going to Macs just as easily as going to Vista."

Ant writes "A Science News article talks about the relationship between city design and health. New cross-disciplinary research is exploring whether urban sprawl makes us soft, or whether people who don't like to exercise move to the sprawling suburbs, or some combination of both." From the article: "So far, the dozen strong studies that have probed the relationships among the urban environment, people's activity, and obesity have all agreed, says Ewing. 'Sprawling places have heavier people... There is evidence of an association between the built environment and obesity.' ... However, University of Toronto economist Matthew Turner charges that 'a lot of people out there don't like urban sprawl, and those people are trying to hijack the obesity epidemic to further the smart-growth agenda [and] change how cities look.' ... 'We're the only ones that have tried to distinguish between causation and sorting... and we find that it's sorting,' [says Turner]. 'The available facts do not support the conclusion that sprawling neighborhoods cause weight gain.'"

Dekortage writes "The New York Times has a report on probiotic food: food that has live bacteria in it. From the article: "[for Dannon's] Activia, a line of yogurt with special live bacteria that are marketed as aiding regularity, sales in United States stores have soared well past the $100 million mark.... Probiotics in food are part of a larger trend toward 'functional foods,' which stress their ability to deliver benefits that have traditionally been the realm of medicine or dietary supplements.""
