redletterdave (2493036) writes 'Apple has purchased Spotsetter, a social search engine that uses big data to offer personalized recommendations for places to go. Spotsetter was designed to combine recommendations from friends with trusted reviews and other data to create more social maps. It would show you which friends were 'experts' in a given area, and you could tag your friends as experts (like LinkedIn) to boost the influence of their recommendations. You could also discover new places by browsing Spotsetter's maps to see where your friends have been and what they've recommended. Spotsetter's app, which was available on iOS and Android, officially closed down just six days ago.'

Zothecula writes "Since its completion in 1963, the Arecibo Observatory in Puerto Rico, with a diameter of 305 m (1,000 ft) and a collecting area of 73,000 square meters (790,000 sq ft), has been the largest single-aperture radio telescope ever constructed. But Arecibo is set to lose its title with construction now underway in Guizhou Province in southern China of the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Upon its expected completion in 2016, FAST will be able to see more than three times further into space and survey the skies ten times faster than Arecibo."

An anonymous reader noted something that will be of interest to the 26% of Slashdot readers who have switched to Chrome: "Google has released Chrome 12, adding plenty of new features to its minimalist web browser and fixing a number of security vulnerabilities. Google software engineer Adrienne Walker said of the safe browsing mode, 'We've carefully designed this feature so that malicious content can be detected without Chrome or Google ever having to know about the URLs you visit or the files you download.'"

Chinobi writes "Di Gao, an assistant professor at the Department of Chemical and Petroleum Engineering at the University of Pittsburgh, has developed a method of separating oil from water within just seconds using a cotton cloth coated in a chemical polymer that makes it both hydrophilic (it bonds with the hydrogen atoms in water) and oleophobic (oil-repelling), making it absolutely perfect for blocking oil and letting water pass through. Gao tested his filter successfully on Gulf Oil water and oil and has an impressive video to demonstrate the results." This is a laboratory demonstration; the technology hasn't been tested at scale.

An anonymous reader writes "While Douglas Adams continues his attempt to set a new record for the longest extended lunch break, geeks all over the universe pay tribute to the beloved author by celebrating the tenth edition of Towel Day. Towel Day is more alive than ever. This year Richard Dawkins, one of Adams' best friends, has tweeted a Towel Day reminder to his numerous followers. The CERN Bulletin has published an article on Towel Day. There has been TV coverage and there will be a radio interview. The Military Republic of the Deltan Imperium, a newly formed micronation, has recognized Towel Day as an official holiday. In Hungary several hundreds of hitchhiker fans want to have a picnic together in a park. And there's a concert, a free downloadable nerdrap album, a free game being released, the list goes on and on."

__roo writes "American researchers think they have found the answer to the question of why overhearing cell phone chats are annoying. According to scientists at Cornell University, when only half of the conversation is overheard, it drains more attention and concentration than when overhearing two people talking. According to one researcher, 'We have less control to move away our attention from half a conversation (or halfalogue) than when listening to a dialogue. Since halfalogues really are more distracting and you can't tune them out, this could explain why people are irritated.' Their study will be published in the journal Psychological Science."

dangle sends in an update from the borderland of Sol. "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. 'Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later,' said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. 'It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery.' The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system."

Megaport writes "Promoting his new series on the Discovery channel, Stephen Hawking has given an interview to the Times in which 'he has suggested that extraterrestrials are almost certain to exist but that instead of seeking them out, humanity should be doing all that it can to avoid any contact.' He says, 'I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach. ... If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans.' Personally, I've always thought that the indigenous people of the world really had no chance to avoid contact here on such a small planet, but is hiding under our collective bed an option for humanity in the wider galaxy?"

suraj.sun writes with a story from LiveScience about just how much attention you can devote to each of the tasks on hand that scream for it: "The brain is set up to manage two tasks, but not more, a new study suggests. That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled. 'What really the results show is that we can readily divide tasking. We can cook, and at the same time talk on the phone, and switch back and forth between these two activities,' said study researcher Etienne Koechlin of the Université Pierre et Marie Curie in Paris, France. 'However, we cannot multitask with more than two tasks.'"

Hugh Pickens writes "The Register reports that News Corp boss Rupert Murdoch, speaking at the National Press Club in Washington, reiterated his disgust at how search engines handle news and called on old media to rethink how their stories are distributed on the web. 'It's produced a river of gold, but those words are being taken mostly from the newspapers,' said Rupert. 'I think they ought to stop it, that the newspapers ought to stand up and let them do their own reporting.' Murdoch added that the iPad was a 'wonderful tool' for listening to music, watching videos and reading newspapers. 'It may well be the saving of the newspaper industry,' by making it cheaper to distribute content to a broader audience, Murdoch said. 'I'm old, I like the tactile experience of the newspaper,' Murdoch said. '(But) if you have less newspapers and more of these, that's OK. It doesn't destroy the traditional newspaper, it just comes in a different form.'"

Most kids hate having their parents join in on a discussion on Facebook, but one 16-year-old in Arkansas hates it so much he has filed suit against his mother, charging her with harassment. From the article: "An Arkadelphia mother is charged with harassment for making entries on her son's Facebook page. Denise New's 16-year-old son filed charges against her last month and requested a no-contact order after he claims she posted slanderous entries about him on the social networking site. New says she was just trying to monitor what he was posting." Seems like he could just unfriend her.

krou writes "Jordanian mayor Mohammed Mleihan has taken a dim view of local newspaper Al-Ghad's April Fools prank, which saw a front page story claiming that 'flying saucers flown by 3m (10ft) creatures had landed in the desert town of Jafr.' The paper claimed that communication networks had gone down, and people were fleeing the area. The mayor called the local security authorities, who combed the area, but they were unable to find any evidence of the aliens. Mr Mleihan is now considering suing because of the distress it caused to residents: 'Students didn't go to school, their parents were frightened and I almost evacuated the town's 13,000 residents. People were scared that aliens would attack them.'" I guess they've never heard of Orson Welles in Jordan.

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"
