alfredos writes "Physicists and engineers at Princeton Plasma Physics Laboratory built tracks inside a fusion reactor and ran a toy train for three days to help them with their calibrations. From the article: 'The modified model of a diesel train engine was carrying a small chunk of californium-252, a radioactive element that spews neutrons as it falls apart. “We needed to refine the calibration technique to make sure we are measuring our neutrons as accurately as possible,” said Masa Ono, the project head of the National Spherical Torus Experiment.'"

afabbro writes "Capsule Hotel Shinjuku 510 once offered a night’s refuge to salarymen who had missed the last train home. Now with Japan enduring its worst recession since World War II, it is becoming an affordable option for people with nowhere else to go. The Hotel 510’s capsules are only 6 1/2 feet long by 5 feet wide. Guests must keep possessions, like shirts and shaving cream, in lockers outside of the capsules. Atsushi Nakanishi, jobless since Christmas says, 'It’s just a place to crawl into and sleep. You get used to it.'”

A story at the BBC takes a look at the use of private game servers for games that tend not to allow them. While most gamers are happy to let companies like Blizzard and NCSoft administer the servers that host their MMORPGs, others want different rules, a cheaper way to play, or the technical challenge of setting up their own. A South African player called Hendrick put up his own WoW server because the game "wasn't available in the country at the time." A 21-year-old Swede created a server called Epilogue, which "had strict codes of conduct and rules, as well as a high degree of customized content (such as new currency, methods of earning experience, the ability to construct buildings and hire non-player characters, plus 'permanent' player death) unavailable in the retail version of the game." The game companies make an effort to quash these servers when they can, though it's frequently more trouble that it's worth. An NCSoft representative referenced the "growing menace" of IP theft, and a Blizzard spokesperson said,"We also have a responsibility to our players to ensure the integrity and reliability of their World of Warcraft gaming experience and that responsibility compels us to protect our rights."

Frequent Slashdot contributor Bennett Haselton writes "A simple experiment shows that it's easy to find the IP addresses used by the UltraSurf anti-censorship program, and block traffic to all of those IP addresses, effectively stopping UltraSurf from working. But this is not a fault of UltraSurf; rather, it demonstrates that an anti-censorship software program can be successful even if it's relatively trivial to block it." Read on for Bennett's analysis.

Houston 2600 writes "Chicago could rake in 'at least $200 million' a year — and wipe out the entire projected deficit for 2009 — by using its vast network of redlight and surveillance cameras to hunt down uninsured motorists, aldermen were told today. The system pitched to the City Council's Transportation Committee by Michigan-based InsureNet would work only if insurance companies were somehow compelled to report the names and license plates of insured motorists. That's already happening daily in 13 states, but not here."

techprophet writes to mention that a new take on self-healing plastic could provide a long-term solution to scratched screens. The new polymer, developed by scientists at the University of Southern Mississippi, uses UV light to reform bonds between molecules rather than embedded healing agents of similar systems. "At the core of their design is polyurethane, which is an elastic polymer that already has decent scratch resistance. To enhance its ability to withstand mechanical damage, Ghosh and Urban added two more components, OXE and CHI. OXE has an unstable chemical structure (a four-membered ring containing three carbons and one oxygen) that makes it prone to being split open. CHI is UV sensitive. The idea is that, if the polyurethane gets damaged by a scratch, the unstable ring structure of OXE will open to create two reactive ends. Then, UV light can trigger CHI to form new links with the reactive ends of OXE and thereby fix the break in the polymer."

hundredrabh writes "Ever had a super needy girlfriend that demanded all your love and attention and would freak whenever you would leave her alone? Irritating, right? Now imagine the same situation, only with an asexual third-generation humanoid robot with 100kg arms. Such was the torture subjected upon Japanese researchers recently when their most advanced robot, capable of simulating human emotions, ditched its puppy love programming and switched over into stalker mode. Eventually the researchers had to decommission the robot, with a hope of bringing it back to life again."

After three years of research, including examining 503 pieces of fluff from his own belly button, Georg Steinhauser has discovered a type of body hair that traps stray pieces of lint and draws them into the navel. Dr Steinhauser's observations showed that "small pieces of fluff first form in the hair and then end up in the navel at the end of the day." Chemical analysis revealed the pieces of fluff were not just made up of cotton from clothing. Wrapped up in the lint were also flecks of dead skin, fat, sweat and dust. Unfortunately, further study has failed to yield a hair or fiber that would give Dr. Steinhauser the last three years of his life back.

A "trailblazing" Norfolk town has begun heating many of its buildings - including the schools - by burning oil made from melted-down cow and pig carcasses. The strategy is described as "equal or lower in carbon footprint than natural gas." Should schools have to offer vegetarian heating?
