Sparrowvsrevolution writes "Four years ago, security researcher Adam J. O'Donnell used game theory to predict in a paper for IEEE Security and Privacy when malware authors would start targeting Macs. Based on some rough assumptions and a little algebra, he found that it would only become profitable to target Apple's population of users when they reached 16% market share. So why are we now seeing mass attacks on Macs like the Flashback trojan when Apple only has 11% market share? O'Donnell says it turns out he may have underestimated the effectiveness of the antivirus used by most Windows users, which now makes overconfident Mac users a relatively vulnerable and much more appealing target. Based on current antivirus detection rates, O'Donnell's equations now show that victimizing Macs becomes a profitable alternative to PCs at just 6.5% market share."

ananyo writes "Scientists have demonstrated that several lab-made variants of DNA can store and transmit information much like the genuine article. DNA is made up of nucleic acid bases — labelled A, C, G and T — on a backbone made of phosphates and the sugar deoxyribose. The artificial polymers, dubbed XNAs, carry the normal genetic 'alphabet' on a backbone made using different sugars. The researchers engineered enzymes that transcribed DNA into the various XNAs, then back into new DNA strands. Faithful genetic transmission over successive DNA-to-XNA cycles allowed researchers to select for only those XNAs that attached to certain target proteins from a pool of random samples — a process akin to evolution over multiple generations (abstract). The research confirms for the first time that replication, heredity and evolution can take place in artificial DNA-like molecules."

MrSeb writes "As part of IBM's Battery 500 project — an initiative started in 2009 to produce a battery capable of powering a car for 500 miles — Big Blue has successfully demonstrated a light-weight, ultra-high-density, lithium-air battery. In it, oxygen is reacted with lithium to create lithium peroxide and electrical energy. When the battery is recharged, the process is reversed and oxygen is released — in the words of IBM, this is an 'air-breathing' battery. While conventional batteries are completely self-contained, the oxygen used in a lithium-air battery comes from the atmosphere, so the battery itself can be much lighter. The main thing, though, is that lithium-air energy density is a lot higher than conventional lithium-ion batteries: the max energy density of lithium-air batteries is theorized to be around 12 kWh/kg, some 15 times greater than li-ion — and more importantly, comparable to gasoline."

Fluffeh writes "The EU Commissioner for the Digital Agenda, Neelie Kroes, has been making some interesting comments about privacy, copyright and many aspects of the digital age. Going so far as to quote the Free Software Foundation and Yochai Benkler, she says: 'Openness is also complex because sometimes it's unclear what it means. ... In the Arab Spring, many brave activists successfully used the open Internet to coordinate peaceful protests. In response, despotic governments sought to control or close down Internet access; and also used ICT tools as a tool of surveillance and repression. We cannot allow democratic voices to be silenced in that way. And I am committed to ensuring "No Disconnect" in countries that struggle for democracy. We must help such activists get around arbitrary disruptions to their basic freedoms.'"

An anonymous reader writes "India has successfully test fired a long-range, nuke-capable missile. Named after Hindu God of fire 'Agni', the ICBM is capable of hitting targets in China, East Africa and parts of Europe. With a successful launch of the missile, India joins an elite group of nations with long-range weapons. 'The BBC's Andrew North in Delhi says Indian officials deny it, but everyone believes the missile is mainly aimed at deterring China. A spokesman for China's Foreign Ministry, Liu Weimin, said his country was not threatened by the test. ... It was only launched once officials were sure they had the best weather conditions — so this was as much a demonstration as a real test, to show India's rivals that it has this kind of capability.'"

Jake Elliott and Jon (not Elwood) Cates are the ones who describe Glitch Art people as 'weirdos within the weirdos' in the context of Notacon 9, which was recently held in Cleveland. It's 'an annual event that focuses on people who like to build, make, break and hack stuff,' and even in the Notacon context the Glitch Artwork crowd stands out. Sit down with Jake and Jon and share their joy in working with "feral glitches... before they are domesticated," and see some of the output from artist Dave Musgrave's circuit-bent consoles.

MikeatWired writes "In a somewhat startling decision, the U.S. Court of Appeals for the Ninth Circuit has ruled that several employees at an executive recruitment firm did not exceed their authorized access to their company's database when they logged into the system and stole confidential data from it. The appellate court's decision affirms a previous ruling made by the U.S. District Court for the Northern District of California. The government must now decide if it wants to take the case all the way to the U.S. Supreme Court. The judge wrote that the Computer Fraud and Abuse Act, under which they were charged, applies primarily to unauthorized access involving external hackers. The definition of 'exceeds authorized access' under the CFAA applies mainly to people who have no authorized access to the computer at all, the judge wrote. The term would also apply to insiders who might have legitimate access to a system but not to specific information or files on the system Applying the language in the CFAA any other way would turn it into a 'sweeping Internet-policing mandate,' he wrote."

An anonymous reader writes "NASA just unveiled its new Sustainability Base — an exceptionally efficient building that harnesses technology developed for the International Space Station. The high-tech complex produces more energy than it consumes and it was just awarded LEED Platinum certification, making it the greenest federal building in the nation. The project features an extensive network of wireless sensors that allow the building to automatically react to changes in weather and occupancy and NASA's forward-osmosis water recycling system, which cuts water use by 90% compared to a traditional building."

Qedward writes "The European Parliament has approved the controversial data transfer agreement, the bilateral PNR (passenger name register), with the US which requires European airlines to pass on passenger information, including name, contact details, payment data, itinerary, email and phone numbers to the Department of Homeland Security. Under the new agreement, PNR data will be 'depersonalized' after six months and would be moved into a 'dormant database' after five years. However the information would still be held for a further 15 years before being fully 'anonymized.'"

Jeremiah Cornelius writes "Khosrow Zarefarid warned of a security flaw in Iran's banking system providing affected institutions the details, including 1,000 captured bank accounts. When the affected banks, including the largest state institutions didn't respond, Khosrow hacked 3 million accounts across at least 22 banks. He then dropped these details — including card numbers and PINs — on his blog. Three Iranian banks Saderat, Eghtesad Novin, and Saman have already warned customers to change their debit card PINs. 'Zarefarid is reportedly no longer in Iran, though it is unclear when he left.'"

trawg writes "The Australian High Court has just dismissed an appeal by Australian and American media companies against ISP iiNet, in what will hopefully be the final step in an ongoing copyright lawsuit drama. The Court noted that 'iiNet had no direct technical power to prevent its customers from using the BitTorrent system to infringe copyright.' Ultimately, the court has held that iiNet's inactivity to act on infringement notices didn't imply any sort of authorization of that infringement by their customers. Good news for Australians as a clear line has been drawn that will help ensure ISPs don't have to bear the cost of policing their customers."

itwbennett writes "Neal Stephenson is shouldering some of the blame for discouraging budding scientists and engineers, saying in a interview that perhaps the dark turn science fiction has taken is 'discouraging budding scientists and engineers.' For his part, Stephenson has vowed to be more optimistic. From the article: 'Speaking before a packed lecture theater at MIT yesterday, Neal Stephenson worried that the gloomy outlook prevalent in modern science fiction may be undermining the genre's ability to inspire engineers and scientists. Describing himself as a "pessimist trying to turn himself into an optimist," and acknowledging that some of his own work has contributed to the dystopian trend, he added "if every depiction of the future is grim...then it doesn't create much of an incentive to building the future."'"

peetm writes "Two 70-year-old papers by Alan Turing on the theory of code breaking have been released by the government's communications headquarters, GCHQ. It is believed Turing wrote the papers while at Bletchley Park working on breaking German Enigma codes. A GCHQ mathematician said the fact that the contents had been restricted 'shows what a tremendous importance it has in the foundations of our subject.'"

First time accepted submitter gstrickler writes "After years of work recovering and analyzing old mission data and vehicle schematics, a just published analysis(Pdf) provides strong evidence for anisotropic thermal radiation being the source of the slowing of the Pioneer 10 and 11 spacecraft. The theory isn't new, but the recovered data and new analysis provide solid evidence that at least 80% of the deceleration is accounted for by anisotropic thermal radiation. Members of The Planetary Society were instrumental in recovering the data and helping fund the analysis. The lesson is, in space, it matters what direction your heat radiating surfaces point."
