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."

fructose writes "The Airborne Laser managed to acquire, track, and illuminate a test missile a few days ago. According to the press release, the Boeing plane 'used its infrared sensors to find a target missile launched from San Nicolas Island, Calif ... issued engagement and target location instructions to the beam control/fire control system ... fired its two solid-state illuminator lasers to track the target and ... fired a surrogate high-energy laser at the target, simulating a missile intercept.' The sensors on board the missile confirmed the 'hit.' Michael Rinn, ABL's program director, said, 'Pointing and focusing a laser beam on a target that is rocketing skyward at thousands of miles per hour is no easy task, but the Airborne Laser is uniquely able to do the job.' The next steps will be to test the high-power laser at full strength in flight and do a complete system test later this year. Its success or failure will determine whether the project gets canceled. Looks like the Real Genius fans out there are finally living the dream."

The blog of Anthony Wesley, an Australian amateur astronomer, has what may be the first photos of a recent comet or asteroid impact on Jupiter, near the south pole. These photos are 11 hours old. The ones at the bottom of the page show three small dark spots in addition to the main dark mark. The Bad Astronomy blog picked up the story a few hours later — but cautions that what we're seeing may not be an impact event. This is all reminiscent of the closely watched impact of comet Shoemaker-Levy on Jupiter in 1994.

Z80xxc! writes "The Anchorage Daily News reports that a 15 mile-long blob of unknown, 'gooey,' probably organic material is floating past communities on Alaska's North Slope. The US Coast Guard sent pollution experts to investigate, who determined that it was not an oil spill or other type of pollution, but were unable to determine what it is. A sample is currently being analyzed by experts in Anchorage, while the blob is following the current northwards."

killmofasta notes an LA Times story on a severe and widespread attack on US military computers that may have originated in Russia. Turns out the military's recent ban on flash drives was a precursor to this attack, which was significant enough that the President and the Defense Secretary were briefed on it. "The 'malware' strike, thought to be from inside Russia, hit combat zone computers and the US Central Command overseeing Iraq and Afghanistan. The attack underscores concerns about computer warfare. 'This one was significant; this one got our attention,' said one defense official, speaking on condition of anonymity when discussing internal assessments. Although officials are withholding many details, the attack underscores the increasing danger and potential significance of computer warfare, which defense experts say could one day be used by combatants to undermine even a militarily superior adversary. ... [A defense official said] 'We have taken a number of corrective measures, but I would be overstating it if I said we were through this.'"

SpaceAdmiral writes "Forget cloning a woolly mammoth — should scientists clone a Neanderthal? Such a feat should be possible soon, although it raises a number of bioethics concerns, including where to draw the line between humans and other animals."

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.'"

The much-anticipated second expansion to World of Warcraft, entitled Wrath of the Lich King, launched on Thursday, introducing a new continent, raising the level cap to 80, and bringing a wealth of new items, spells, dungeons, and monsters to the popular MMO. Crowds gathered and lines formed outside stores around the world leading up to the release. Massively has put together a series of articles for players wishing to familiarize themselves with the expansion, and CVG has a piece discussing the basics as well. It didn't take long for the first person to reach level 80; a French player called "Nymh" reached the level cap on his Warlock only 27 hours after the expansion went live. Not to be outdone, a guild named "TwentyFifthNovember" managed to get at least 25 raiders to 80 and then cleared all of the current expansion raid content less than three days after the launch. Fortunately for them, the next three content patches are each expected to contain new, more difficult raids.

theodp writes "TechFlash reports that Microsoft bigwigs like Craig Mundie and Bill Gates (when he still worked there) have been secretly moonlighting at Intellectual Ventures (IV), the 'patent extortion fund' run by Bill's pal Nathan Myhrvold. A Microsoft spokesman confirmed that its technologists have been sitting in on IV-sponsored 'innovation sessions,' where their pearls of wisdom were captured and turned into patent applications for Searete, an IV shadow corporate entity. And if all goes well, Searete will soon enjoy exclusive rights to the fruit of the brainstorming, which includes processes ranging from determining and rewarding 'influencers' to treating malaria, HIV, TB, hepatitis, smallpox, and cancer."

mallumax writes "David Pogue of New York Times has reviewed the Pico, which is a pocket projector from Optoma. The review is quite entertaining (Pogue projects the images on to a plane's ceiling, leaving passengers baffled) and detailed. The highlights are: It is a pocket-sized projector which runs on batteries and can project images and videos from a variety of sources like iPhone, iPod and DVD players with a 480x320px resolution, with a maximum screen size of 65 inches at 8.5 feet. It uses a non-replaceable 10,000 hour LED lamp and a DLP chip from Texas Instruments. The battery lasts for 90 minutes and can be recharged through USB or with its own power cord. The device weighs 115g and comes with an inbuilt speaker which is practically useless. If you want one, it will set you back by $430."

coondoggie sends this excerpt from NetworkWorld: "The US Army Research Office and the National Security Agency (NSA) are together looking for some answers to their quantum physics questions. ... The Army said quantum algorithms that are developed should focus on constructive solutions [PDF] for specific tasks, and on general methodologies for expressing and analyzing algorithms tailored to specific problems — though they didn't say what those specific tasks were ... 'Investigators should presuppose the existence of a fully functional quantum computer and consider what algorithmic tasks are particularly well suited to such a machine. A necessary component of this research will be to compare the efficiency of the quantum algorithm to the best existing classical algorithm for the same problem.'"

An anonymous reader writes "API Lead at Twitter, Alex Payne, writes today that the Internet was 'built wrong,' and continues to be accepted as an inferior system, due to a software engineering philosophy called Worse Is Better. 'We now know, for example, that IPv4 won't scale to the projected size of the future Internet. We know too that near-universal deployment of technologies with inadequate security and trust models, like SMTP, can mean millions if not billions lost to electronic crime, defensive measures, and reduced productivity,' says Payne, who calls for a 'content-centric approach to networking.' Payne doesn't mention, however, that his own system, Twitter, was built wrong and is consistently down."

Slatterz writes "Apple co-founder Steve Wozniak, better known in the industry as 'Woz,' believes that the iPod is on its way out and has revealed his discomfort with some aspects of the iPhone. Wozniak said that the iPod has had a long time as the world's most popular media player, and that it will fall from grace due to oversupply. Wozniak also commented on the iPhone's proprietary nature and locked service provider, and compared it to Google's open Android platform. 'Consumers are not getting all they want when companies are very proprietary and lock their products down,' he said. 'I would like to write some more powerful apps than what you're allowed.'"

Smivs writes "New research shows how steel will fail at high temperatures because of the magnetic properties of the metal. Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors. The New York buildings fell when their steel backbones lost strength in the fires that followed the plane impacts. Dr Sergei Dudarev told the British Association Science Festival that improved steels were now being sought. The principal scientist at the United Kingdom Atomic Energy Authority (UKAEA) said one of the first applications for these better performing metals would be in the wall linings of fusion reactors."

trogador writes "Researchers from Imperial College London are improving the Da Vinci surgical robot by installing an eye-tracker, which allows surgeons to control the robot's knife simply by looking at the patient's tissues on a screen. Tracking the eyes can generate a 3D map, which in turn can make moving organs — like a beating heart — appear to stand still for easier operation. Other features include 'see-through' tissues on the surgeon's screen (so tumors can be seen underneath tissues) and 'no-cut' zones, places where the robot won't allow the surgeon to cut by mistake. Says ICL Professor Guang Zhong Yang, 'We want to empower the robot and make it more autonomous.'"
