astroengine writes "New research shows the jumbled ice blocks crowning the surface of Jupiter's icy moon Europa are signs of large liquid lakes below, a key finding in the search for places where life might exist beyond Earth. Drawing from studies of underground volcanoes in Iceland and Antarctica, scientists ran computer models to see if the chaotic formations on Europa's surface could be explained by the same geologic processes seen on Earth. It turns out that not only could this be further evidence for a sub-surface ocean, but also a mechanism that mixes ice and water, circulating nutrients and energy to get from the frozen surface to the ocean below."

First time accepted submitter rnswebx writes "Two patents that chip designer Rambus used to win patent lawsuits against Nvidia, HP, and others have been declared invalid by the USPTO." The Inquirer has a similar story up, with appropriately snarky sub-head.

An anonymous reader writes "Fermilab today announced that scientists working at the CDF (Collision Detector at Fermilab) experiment confirmed the observation of a new particle, the Xi-sub-b. The Xi-sub-b is categorized as a baryon, which are formed of three quarks. Commonly known baryons include the proton as well as the neutron."

Oooskar writes "SLAM (Simultaneous Localization and Mapping), a technique invented by NASA, defines the concept of building a 3D-map of the environment and simultaneously computing the position within it. Based on SLAM, Swedish startup 13th Lab has implemented real-time sub-centimeter local 3D-positioning by using only the sensors, most importantly the camera, already present in most mobile devices (demo video). The technology will be made available as a software platform for developers (sign up for beta). A first application demonstrating the technology has just been released for the iPad2. The technology should be available on other devices with similar computational power soon."

theodp writes "Two more software products will be going to Google Software Heaven shortly. On Friday, Google issued a death certificate for Google Health (date of death = Jan. 1, 2012), and added that the lights will go out on Google PowerMeter on Sep. 16, 2011. 'We've observed that Google Health is not having the broad impact that we hoped it would,' said Google. 'There has been adoption among certain groups of users like tech-savvy patients and their caregivers, and more recently fitness and wellness enthusiasts. But we haven't found a way to translate that limited usage into widespread adoption in the daily health routines of millions of people.' Regarding PowerMeter, Google's 'Green Energy Czar' had this to say: 'We're pleased that PowerMeter has helped demonstrate the importance of this access and created something of a model. However, our efforts have not scaled as quickly as we would like, so we are retiring the service.' Google added that the White House will carry on the fight after being inspired by success stories like the Harker School (tuition: $36,435), which used grant money to acquire off-the-shelf sub-metering technology that revealed their energy bill could be reduced by not air conditioning the gym from 9pm-3am."

Hugh Pickens writes writes "Medical groups from the American Medical Association to the American Society of Microbiology have appealed to the government and industry for years to restrict the practice of providing sub-therapeutic doses of antibiotics for livestock, lest critical antibiotics become useless for human treatments. Now Tom Laskawy reports that a coalition of environmental groups has decided to sue the Federal Drug Administration to follow its own safety findings and withdraw approval for most non-therapeutic uses of penicillin and tetracyclines in animal feed to healthy livestock when it's not medically necessary. 'While this may cause eyerolls among some who look at this as "just another lawsuit," there's something very important going on with the courts and contested science right now,' writes Laskawy. 'As it happens, one of the main roles of a judge is as "finder of fact." In practice, this means that judges determine whether scientific evidence is compelling enough to force government action."'"

gabbo529 writes "NASA scientists have discovered new information on one of Jupiter's moons, indicating it has a molten magma sub-surface (abstract). This discovery, made using data analysis from NASA's Galileo spacecraft, reveals why that particular moon is the most volcanic object known in the solar system. The moon, which is named Io, produces about 100 times more lava each year than all the volcanoes on Earth combined. The global magma ocean about 30 to 50 kilometers (20 to 30 miles) beneath Io's surface explains the moon's activity." Science has a nice graphic, too.

jamie points out an opinion piece by Columbia professor Mark C. Taylor in Nature News decrying the state of PhD education in the US, calling it "broken and unsustainable." Quoting: "The necessary changes are both curricular and institutional. One reason that many doctoral programmes do not adequately serve students is that they are overly specialized, with curricula fragmented and increasingly irrelevant to the world beyond academia. Expertise, of course, is essential to the advancement of knowledge and to society. But in far too many cases, specialization has led to areas of research so narrow that they are of interest only to other people working in the same fields, subfields or sub-subfields. Many researchers struggle to talk to colleagues in the same department, and communication across departments and disciplines can be impossible. If doctoral education is to remain viable in the twenty-first century, universities must tear down the walls that separate fields, and establish programmes that nourish cross-disciplinary investigation and communication. They must design curricula that focus on solving practical problems, such as providing clean water to a growing population. Unfortunately, significant change is unlikely to come from faculty members, who all too often remain committed to traditional approaches."

An anonymous reader writes "Three days ago Facebook finalized their list of accepted ad networks for use within Facebook Apps; AdSense being an (unsurprising?) omission from the list, stating that any missing ad network had yet to agree to the Facebook TOS. Facebook developers were quick to point out the only losers in this cold-war between Facebook and Google are the developers themselves. Other devs go on to clarify that the reputations of some of the accepted networks is shady at best, leaving developers with sub-par options to monetize their work on the Facebook platform."

Mr.Intel writes "Last night's State of the Union Address contained ten things (and four outrages) technical professionals need to know about the President's plans, and how his policies might affect you, your employer, and your family well into the future."

nk497 writes "A new OECD report suggests the cyberwar threat is over-hyped. A pair of British researchers have said states are only likely to use cyberattacks against other states when already involved in military action against them, and that sub-state actors such as terrorists and individual hackers can't really do much damage. Dr. Ian Brown said, 'We think that describing things like online fraud and hacktivism as cyberwar is very misleading.'"

arcticstoat writes "PC gamers who are sick of being constantly distracted by whirring fans could now have a helping hand from a new wireless graphics card. Galaxy sub-brand KFA2 has announced a graphics card with no display outputs. Instead, the KFA2 GTX 460 WHDI uses a wireless link to send the display output from your PC to your screen, whether that's a conventional monitor or the HD TV in your lounge. You just need to attach the bundled receiver to the back of your chosen screen and you're done. With a wireless keyboard and mouse, you could place your PC at the other end of the room, letting you crank up those fans without having to listen to the whirring next to you."

eldavojohn writes "Back in 2006 there was a lot of talk of testing String Theory. Well, today CERN has released a statement for the Compact Muon Solenoid Experiment. The short of it is simply that as far as they could tell, 'No experimental evidence for microscopic black holes has been found.' The long statement indicates that since the highly precise CMS detector found no spray of sub-atomic particles of normal matter while LHC smashed particles together, the hypothesis by String Theory that micro black holes would be formed and quickly evaporated in this experiment was incorrect. These tests have given the team confidence to say that they can exclude a 'variety of theoretical models' for the cases of black holes with a mass of 3.5-4.5 TeV (1012 electron volts). Not Even Wrong points us to the arxiv prepublication for those of you well versed in Greek. While you may not be able to run around claiming that String Theory is dead and disproved, evidently there are some adjustments that need to be made."

jamie found a story up on Daily Kos revealing that the polling firm they had contracted with for 18 months, Research 2000 or R2K, apparently made up or at least manually tweaked its polling results. The blog published a preliminary report by a team of statistics gurus (Mark Grebner, Michael Weissman, and Jonathan Weissman), and it is an exemplar of clarity and concision. The team reports, "We do not know exactly how the weekly R2K results were created, but we are confident they could not accurately describe random polls." Daily Kos will be filing a lawsuit against its former pollster. "For the past year and a half, Daily Kos has been featuring weekly poll results from the Research 2000 (R2K) organization. These polls were often praised for their 'transparency,' since they included detailed cross-tabs on sub-populations and a clear description of the random dialing technique. However, on June 6, 2010, FiveThirtyEight.com rated R2K as among the least accurate pollsters in predicting election results. Daily Kos then terminated the relationship. One of us (MG) wondered if odd patterns he had noticed in R2K's reports might be connected with R2K's mediocre track record, prompting our investigation of whether the reports could represent proper random polling. ... This posting is a careful initial report of our findings, not intended to be a full formal analysis but rather to alert people not to rely on R2K's results."

An anonymous reader writes "Engineers at the Belgian research institute IMEC are looking at the use of silicon transistors in the sub-threshold region of their operation as a way of pursuing ultra-low power goals. A chip the engineers are designing for biomedical applications could have blocks designed to operate at 0.2 or 0.3 volts, researchers said, according to EE Times. The threshold voltage is the point at which the transistor nominally switches off. Operating a transistor when it is 'off' would make use of the leakage conduction that is normally seen as wasted energy, according to the article."

snydeq writes "InfoWorld's Peter Wayner offers seven reasons why web designers will remain loyal to Flash for rich web content, despite 'seductive' new capabilities offered by HTML5. Sure, HTML5 aims to duplicate many of the features that were once the sole province of plugins (local disk storage, video display, better rendering, algorithmic drawing, and more) and has high-profile backers in Google and Apple, but as Wayner sees it, this fight is more about designers than it is about technocrats and programmers. And from its sub-pixel resolution, to its developer tools, to its 'write once, play everywhere' functionality, Flash has too much going for it to fall by the wayside. 'The designers will make the final determination. As long as Flash and its cousins Flex and Shockwave remain the simplest tools for producing drop-dead gorgeous websites, they'll keep their place on the Internet.'"

Dotnaught writes "Greg Slepak, founder of software company Tao Effect, wrote Apple CEO Steve Jobs to complain about Apple's mandate that iPhone applications be originally written in C/C++/Objective-C. Job's response was to endorse a post by John Gruber on the Daring Fireball blog. Jobs called it 'very insightful,' suggesting Gruber's prediction that third-party iPhone development tools are out might be right. Jobs sent a second reply that also doesn't bode well for third-party iPhone development tools: 'We've been there before, and intermediate layers between the platform and the developer ultimately produces sub-standard apps and hinders the progress of the platform.'"

astroengine writes "The UK Infrared Telescope in Hawaii has discovered a lone, cool brown dwarf called UGPSJ0722-05. As far as sub-stellar objects go, this is a strange one. For starters, it's the coolest brown dwarf ever discovered (and astronomers using the UKIRT should know; they are making a habit of finding cool brown dwarfs). Secondly, it's close. In fact, it's the closest brown dwarf to Earth, at a distance of only 10 light years. And thirdly, it has an odd spectroscopic signature, leading astronomers to think that this might be the discovery of a whole new class of brown dwarf."

An anonymous reader writes "Toshiba plans to spend about $159.8 million this year to build a test production line for NAND flash memory chips of less than 25 nanometers. The company hopes to kick off mass production of the chip as early as 2012. The fabrication facility for this key NAND flash memory will be located at Yokkaichi, Mie Prefecture."

Korgan writes "In what must be a first in the face of ACTA and US trade negotiations pressure, a Parliamentary select committee has released a draft bill that explicitly declares that software will no longer be patentable in New Zealand. FTA: 'Open source software champions have been influential in excluding software from the scope of patents in the new Patents Bill. Clause 15 of the draft Bill, as reported back from the Commerce Select Committee, lists a number of classes of invention which should not be patentable and includes the sub-clause "a computer program is not a patentable invention."'"
