Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

dnaumov writes "FreeNAS, a popular, free NAS solution, is moving away from using FreeBSD as its underlying core OS and switching to Debian Linux. Version 0.8 of FreeNAS as well as all further releases are going to be based on Linux, while the FreeBSD-based 0.7 branch of FreeNAS is going into maintenance-only mode, according to main developer Volker Theile. A discussion about the switch, including comments from the developers, can be found on the FreeNAS SourceForge discussion forum. Some users applaud the change, which promises improved hardware compatibility, while others voice concerns regarding the future of their existing setups and lack of ZFS support in Linux."

A course at the University of Michigan ends with a live concert featuring students using iPhones as instruments. “Building a Mobile Phone Ensemble“ teaches students to code musical instruments for the iPhone, using the Apple-provided software-development kit. Georg Essl, assistant professor of computer science and music, says, "What’s interesting is we blend the whole process. We start from nothing. We teach the programming of iPhones for multimedia stuff, and then we teach students to build their own instruments.”

paulraps writes "The Pirate Bay is to be bought for $7.8 million by Global Gaming Factory X, a Swedish company specializing in internet café management software, the company has announced. As well as taking over the controversial brand, GGF has also bought Peerialism, a small IT company with roots at Sweden's Royal Institute of Technology, which has developed a new file sharing technology. The acquisitions mean that GGF will be at the heart of 'the international digital distribution market,' allowing it to introduce a new pay model for file sharing." Reader pyzondar adds "However, the press statement also states that the deal will only go through 'if GGF and its Board of Directors can use the asset in a legal and appropriate way.'"

overthinkingit writes "A scientist has tried to apply serious math and physics, including the Law of Cosines, to analyze how the DeLorean in Back to the Future travels through both Time AND Space: 'in order to pull off the kind of time travel we see in the Back To The Future trilogy — the kind where the traveler is transposed in time, but remains stationary in the same relative position to where he/she left — the DeLorean would have to be an outstanding space ship, in addition to its already laudable work as a time-ship. According to Doc Brown's stopwatch, Einstein the dog travels precisely one minute into the future on this first jump, arriving, relative to their frame of reference, at the same location he left. But how far has this reference frame itself traveled during that one minute?'"

SlappingOysters writes "Racism in video games has been a key topic of discussion in the game industry this year, thanks in large part to the controversy surrounding the Resident Evil 5 launch trailer. In this article, GamePlayer speaks to developers, publishers, activists and journalists about the issue to get various perspectives and insights into how the video game industry is moving forward on the topic of racism. A related piece also has interviews with Sue Clark from the UK's Classification Board and Dr. Griseldis Kirsch, a lecturer in Contemporary Japanese Studies, about how racism in video games is viewed by the BBFC and Japan respectively."

jage2 writes "Researchers say they have located the world's oldest stash of marijuana in a tomb in a remote part of China. The cache of cannabis is about 2,700 years old and was clearly 'cultivated for psychoactive purposes,' rather than as fibre for clothing, or as food, says a research paper in the Journal of Experimental Botany. The 789 grams of dried cannabis was buried alongside a light-haired, blue-eyed Caucasian man, likely a shaman of the Gushi culture, near Turpan in northwestern China."

The NYTimes reports that Atlantic is the first major label to report getting a majority of its revenue from digital sales, not CDs. Analysts say that Atlantic is out in front — the industry as a whole isn't expected to hit the 50% mark until 2011. By 2013, music industry revenues will be 37% down from their 1999 levels (when Napster arrived on the scene), according to Forrester. "'It's not at all clear that digital economics can make up for the drop in physical,' said John Rose, a former executive at EMI ... Instead, the music industry is now hoping to find growth from a variety of other revenue streams it has not always had access to, like concert ticket sales and merchandise from artist tours. ... In virtually all... corners of the media world, executives are fighting to hold onto as much of their old business as possible while transitioning to digital — a difficult process that NBC Universal's chief executive ... has described as 'trading analog dollars for digital pennies.'"

phorm writes "BBC is carrying an article which states that 90% of visitors to Europe's 'video game addiction clinic' are not, in fact, addicted. The problem is a social one rather than a psychological issue. In other words, the patients have turned to heavy gaming because they felt they didn't fit in elsewhere, or that they fit in better 'in the game' than elsewhere in 'the real world.' This has been discussed before, with arguments ranging from gaming being a good way to socialize, the clinical definition of gaming addiction, and claims than males are wired for video-game addiction."

An anonymous reader writes "I'm sure this is something all older Slashdotters are aware of: as I get older my once-sharp brain is, well, getting worse. In particular, I'm not able to remember things as well as I once did. As a geek my capacity in this area was always what defined me as a geek. Nowadays things seem to go in OK, but then leak out. A few weeks later I've mostly forgotten. So, I ask Slashdot: how do you cope with your mind getting older? What's your trick? Fish-oil? Brain Training on the DS? Exercise? Or just trying harder to remember things?"

An anonymous reader writes "Dissipation of contrails with a powerful microwave beam aligned behind aircraft engines is being touted as a possible solution to help address air transport's effects on the climate. 'The remote heating of condensation nuclei could be achieved by applying electromagnetic radiation, such as microwaves,' says Cranfield University's Frank Noppel. 'Depending on assumptions made, calculation shows that the power required for such a device could be as little as 0.1% of the engine power.'"

As Halo Wars gets closer to its February release, details are gradually emerging about the game. In an interview with CVG, lead designer Graeme Devine claimed that the controls are actually better than those of a PC RTS, and said the downloadable content for the game is mostly done already, but will be held back until well after the release. Giant Bomb got some hands-on time with the game, and said the controls the controls "do work well enough, even if they're geared more toward broad tactical strokes than intensive small-group micromanagement." Kotaku has further details about the game as well. A video showing some of the gameplay is also available. Ensemble Studios has explicitly denied the possibility of a PC port.
