astroengine writes "Scientists using the Hubble Space Telescope have found plumes of water vapor shooting off the southern pole of Europa, an ice-covered moon of Jupiter that is believed to have an underground ocean. If confirmed — so far the plumes have only been spotted once — the finding could have implications for the moon's suitability for life and help explain why its surface appears relatively young and crater-free. "The plumes are incredibly exciting, if they are there. They're bringing up material from in the ocean, perhaps there's organic material that will be laying on the surface of the south pole. Those are the things that we want to know about," James Green, head of NASA's planetary science programs, told reporters at the American Geophysical Union conference in San Francisco on Thursday."

Frequent contributor Bennett Haselton writes: "Google has fixed a vulnerability, first discovered by researcher Gergely Kalman, which let users search for credit card numbers by using hex number ranges. However, Google should have acknowledged or at least responded to the original bug finder (and possibly even paid him a bounty for it), and should have been more transparent about the process in general." Read on for the rest of the story.
KentuckyFC writes "During the Cold War, the US and the Soviet Union battled on many fronts to demonstrate their superior technical and scientific achievements. While the race to put a human in space and then on the Moon is famous, a much less well-known battlefront was the unconventional science of parapsychology, or psychotronics as the Soviets called it. Now a new review of unconventional research in the Soviet Union reveals the scale of this work for the first time and the cost: as much as $1 billion. The Soviets had programs studying how "human energy" could influence other objects and how this energy could be generated independently of humans using a device called 'cerpan'. The Soviets also had a mind control program similar to the CIA's infamous MKULTRA project. Interestingly, the Soviets included non-local physics in this work, such as the Aharonov-Bohm effect in which an electromagnetic field can influence a particle confined to region where the field strength is zero. And they built a number of devices that exploited the effect, although research in this area appears to have ended in 2003."
astroengine writes "A coolant system glitch on the International Space Station has forced several of the orbital outpost's modules offline as astronauts and ground control manage the problem. The crew are not in danger and ground control teams are currently working to see how best to troubleshoot. The issue, that occurred early on Wednesday, focuses on one of the space station's two external ammonia cooling loops, along which the station's electrical systems use to regulate their temperatures. The loop 'automatically shut down when it reached pre-set temperature limits,' said NASA in a statement. It is thought that a flow control valve in the ammonia pump itself may have malfunctioned."
ananyo writes "A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter cosmos where there is no gravity. Maldacena's idea thrilled physicists because it offered a way to put the popular but still unproven theory of strings on solid footing — and because it solved apparent inconsistencies between quantum physics and Einstein's theory of gravity. It provided physicists with a mathematical Rosetta stone, a 'duality', that allowed them to translate back and forth between the two languages, and solve problems in one model that seemed intractable in the other and vice versa. But although the validity of Maldacena's ideas has pretty much been taken for granted ever since, a rigorous proof has been elusive. In two papers posted on the arXiv repository, Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues now provide, if not an actual proof, at least compelling evidence that Maldacena's conjecture is true."
judgecorp writes "Google has opened data centers in Singapore and Taiwan to serve the boom in Asian Internet users. But it canceled a $300 million data center project in Hong Kong to focus on the Taiwan site and the smaller one in Singapore. Officially the problem was lack of space in Hong Kong, but China's repressive attitude to the Internet (and the history of the Chinese hack on Gmail in 2010) must have contributed to the move."
MightyMait writes "There's a plan underway to build a space agency run by African nations, and there is a (non-fictional) George Clooney connection. This BBC article details the history of space exploration in Africa as well as current efforts. Quoting: 'To Western eyes, it may seem rather inappropriate to launch space programs in sub-Saharan Africa, where nearly 70% of the population still lives on less $2 a day. Yet Joseph Akinyede, director of the African Regional Center for Space Science and Technology Education in Nigeria, an education center affiliated with the United Nations Office for Outer Space Affairs, says that the application of space science technology and research to "basic necessities" of life – health, education, energy, food security, environmental management – is critical for the development of the continent.'"
Hugh Pickens DOT Com writes "Dennis Overbye reports in the NY Times that two years ago Richard Dawkins and Lawrence Krauss set off on a barnstorming tour to save the world from religion and promote science. Their adventure is now the subject of The Unbelievers, a new documentary. 'If you think a road trip with a pair of intellectuals wielding laptops is likely to lack drama, you haven't been keeping up with the culture wars,' writes Overbye. The scientists are mobbed at glamorous sites like the Sydney Opera House. Inside, they sometimes encounter clueless moderators; outside, demonstrators condemning them to hellfire. At one event, a group of male Muslim protesters are confronted by counterprotesters chanting, 'Where are your women?' 'Travelogue shots, perky editing and some popular rock music, as well as interview bits with such supportive celebrities as Woody Allen, Cameron Diaz, Sarah Silverman and Ricky Gervais, shrewdly enliven the brainy — but accessible — discourse,' writes Gary Goldstein in the LA Times, 'but mostly the movie is an enjoyably high-minded love fest between two deeply committed intellectuals and the scads of atheists, secularists, free-thinkers, skeptics and activists who make up their rock star-like fan base.' The movie ends at the Reason Rally in Washington, billed as the largest convention of atheists in history. Dawkins looks out at the crowd standing in a light rain and pronounces it 'the most incredible sight I can remember ever seeing' and declares that too many people have been cowed out of coming out as atheists, secularists or agnostics. 'We are far more numerous than anybody realizes.'"
coondoggie writes "Private Mars mission planners said today that Lockheed Martin is on board to build the spacecraft that would land a technology demonstration robot on the Red Planet by 2018. The Mars One group ultimately wants to establish a human outpost on Mars. The lander robot would use technology Lockheed previously built for NASA's Phoenix lander, which touched down on Mars in 2008. The Mars One lander will evaluate the use of the Phoenix design for the Mars One mission and identify any modifications that are necessary to meet future requirements. In addition, the mission would go a long way toward determining the cost and schedule of future missions."
KentuckyFC writes "Goldilocks zones are regions around stars that are 'just right' for liquid water and for the chemistry of life as we know it. Now one cosmologist points out that the universe must have been through a Goldilocks epoch, a period in which warm, watery conditions could have existed on almost any planet in the entire cosmos. The key phenomenon here is the cosmic background radiation, the afterglow of the Big Bang which was blazing hot when it first formed. But as the universe expanded, the wavelength of this radiation increased, lowering its energy. Today, it is an icy 3 Kelvin. But somewhere along the way, it must have been between 273 and 300 Kelvin, just right to keep water in liquid form. According to the new calculations, this Goldilocks epoch would have occurred when the universe was about 15 million years old and would have lasted for several million years. And since the first stars had a lifespan of only 3 million years or so, that allows plenty of time for the heavy elements to have formed which are necessary for planet formation and the chemistry of life. Indeed, if live did evolve a this time, it would have predated life on Earth by about 10 billion years."
astroengine writes "The site where NASA's Mars rover Curiosity landed last year contains at least one lake that would have been perfectly suited for colonies of simple, rock-eating microbes found in caves and hydrothermal vents on Earth. Analysis of mudstones in an area known as Yellowknife Bay, located inside the rover's Gale Crater landing site, show that fresh water pooled on the surface for tens of thousands — or even hundreds of thousands — of years. 'The results show that the lake was definitely a habitable environment,' Curiosity lead scientist John Grotzinger, with the California Institute of Technology, told Discovery News. The finding was announced at the American Geophysical Union conference in San Francisco."
sfcrazy writes "A giant exoplanet that is in the most distant orbit ever seen around its host star, has been recently discovered. Dubbed HD 106906 b, the newly discovered planet is relatively young (13 million years old, compare this to our 4.5 billion years old Earth) and bigger than any other planet discovered till date. It is 11 times the size of Jupiter, and that's what makes it a most singular discovery."
An anonymous reader writes in with this link about the advances in China's lunar program. "A $30 million Google-backed competition to land a spacecraft on the moon may be about to be scooped. China's Chang'e 3 probe successfully put itself into lunar orbit on Friday in preparation for an attempted touchdown around Dec. 14. China won't be winning the prize money, which is reserved for privately funded, previously enrolled teams, not government agencies."
First time accepted submitter prajendran writes "James Hansen, the former director of the Goddard Institute of Space Sciences, has been a strong defender of using nuclear energy to replace coal and renewable energy. He and three other researchers had written a letter, arguing just this. In this interview with rediff.com, an Indian news site, he was asked to address some concerns surrounding the issue, especially given the strong feelings generated by it. It may not be Hansen's best interview, but it did bring out his passionate side."

MojoKid writes "A leaked Intel roadmap for solid state storage technology suggests the company is pushing ahead with its plans to introduce new high-end drives based on cutting-edge NAND flash. It's significant for Intel to be adopting 20nm NAND in its highest-end data center products, because of the challenges smaller NAND nodes present in terms of data retention and reliability. Intel introduced 20nm NAND lower in the product stack over a year ago, but apparently has waited till now to bring 20nm to the highest end. Reportedly, next year, Intel will debut three new drive families — the SSD Pro 2500 Series (codenamed Temple Star), the DC P3500 Series (Pleasantdale) and the DC P3700 Series (Fultondale). The Temple Star family uses the M.2 and M.25 form factors, which are meant to replace the older mSATA form factor for ultrabooks and tablets. The M.2 standard allows more space on PCBs for actual NAND storage and can interface with PCIe, SATA, and USB 3.0-attached storage in the same design. The new high-end enterprise drives, meanwhile, will hit 2TB (up from 800GB), ship in 2.5" and add-in card form factors, and offer vastly improved performance. The current DC S3700 series offers 500MBps writes and 460MBps reads. The DC P3700 will increase this to 2800MBps read and 1700MBps writes. The primary difference between the DC P3500 and DC P3700 families appears to be that the P3700 family will use Intel's High Endurance Technology (HET) MLC, while the DC P3500 family sticks with traditional MLC."

SternisheFan sends this excerpt from a JPL news release: "NASA's Cassini spacecraft has obtained the highest-resolution movie yet of a unique six-sided jet stream, known as the hexagon, around Saturn's north pole. This is the first hexagon movie of its kind (GIF), using color filters, and the first to show a complete view of the top of Saturn down to about 70 degrees latitude. Spanning about 20,000 miles (30,000 kilometers) across, the hexagon is a wavy jet stream of 200-mile-per-hour winds (about 322 kilometers per hour) with a massive, rotating storm at the center. There is no weather feature exactly, consistently like this anywhere else in the solar system. 'The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable,' said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena. 'A hurricane on Earth typically lasts a week, but this has been here for decades — and who knows — maybe centuries.'"
Kristian vonBengtson writes "Wanna build your own space capsule capable of doing an atmospheric re-entry on a suborbital mission? Well, here are some production hints and a visual guide." The initial stages begin with sketches on paper before moving to 3D design software. He writes, "A whole bunch of sketches were done to get some kind of initial idea of the size, subsystems layout and how to actually produce the capsule while keeping an open structure for further development and potential changes. One of the main concerns was the small size and the ability to easy install and replace avionics. This led to the decision that all external side panels will have to accommodate being taken on and off – no welding, only on the main structure." Afterward, he moves on to show the final metal cuts and how the pieces are put together via bolts and welding.
