mathfeel writes "Indulge me in some post hoc reasoning here: After last week's episode of This American Life "Mr. Daisey and the Apple Factory", a very interesting show, Apple announced that 'For the first time, Apple has released a list of companies that build its products around the world. In another first, the company also announced that it will allow an independent third party to check on working conditions at those factories, and to make its findings public.' But before you celebrate Apple's gesture (or complain about the potential increase in electronic price): 'It doesn't appear that Apple's partnership with the FLA will increase transparency in this regard either. The FLA will audit 5% of the factories that make Apple products, but like Apple, it will not name which ones it checks or where it finds violations.'"

First time accepted submitter sabre86 writes "At the American Institute for Aeronautics and Astronautics Aerospace Sciences Meeting in Nashville, NASA engineers unveiled the newly open sourced OpenVSP, software that allows users to construct full aircraft models from simple parameters such as wing span and fuselage length, under the NASA Open Source Agreement. Says the website, 'OpenVSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis.'"

sciencehabit writes "If you've ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world's tiniest ear. The 'nano-ear,' a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of 'acoustic microscopy,' in which organisms are studied using the sound they emit."

Hugh Pickens writes writes "Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction but now geothermal energy developers plan use a new technology called Enhanced Geothermal Systems (EGS) to pump 24 million gallons of water into the side of the dormant Newberrry Volcano, located about 20 miles south of Bend, Oregon in an effort to use the earth's heat to generate power. 'We know the heat is there,' says Susan Petty, president of AltaRock Energy, Inc. of Seattle. 'The big issue is can we circulate enough water through the system to make it economic.' Since natural cracks and pores do not allow economic flow rates, the permeability of the volcanic rock can be enhanced with EGS by pumping high-pressure cold water down an injection well into the rock, creating tiny fractures in the rock, a process known as hydroshearing. Then cold water is pumped down production wells into the reservoir, and the steam is drawn out. Natural geothermal resources only account for about 0.3 percent of U.S. electricity production, but a 2007 Massachusetts Institute of Technology report projected EGS could bump that to 10 percent within 50 years, at prices competitive with fossil-fuels. 'The important question we need to answer now,' says USGS geophysicist Colin Williams, 'is how geothermal fits into the renewable energy picture, and how EGS fits. How much it is going to cost, and how much is available.'"

TomOfAmalfi writes "Andrea Rossi says he can provide domestic energy sources (about 10 kW) based on his E-Cat system (a Low Energy Nuclear Reaction or Cold Fusion energy source) for between 100 and 150 US$/kW and begin shipping this year. Many people are skeptical about Rossi's claims because he has not explained how his 'reactors' work (apparently the reactors contain ingenious security devices to prevent reverse engineering), there is no theoretical basis to support his process, and no one has supplied independent measurements to support the specs on his black boxes. However, buried at the bottom of a NASA web page there is a comment about progress in 'cold fusion' research and a link to the slides used in a September 2011 presentation (PDF) which talks about LENR research. NASA has also released a video describing the great benefits we will get from NASA LENR research. Could Rossi be on to something?"

New submitter cervesaebraciator writes "The Atlantic Wire reports that the Navy has a tested solution to the possible mining of the Straight of Hormuz. The Navy has 80 dolphins in San Diego Bay trained to use their own sonar to detect mines. When they find the mines, the dolphins drop an acoustic transponder nearby, so that human divers might return to defuse it. Retired Adm. Tim Keating cannot say, however, whether the dolphins will be used in the Straight." The Obama administration has reportedly warned Iran that closing the Straight would provoke an American response.

revealingheart writes "BBC reports that Sweden is allowing one citizen per week to take control of its official Twitter feed, in what's been described as 'the world's most democratic Twitter experiment.' Adam Arnesson, a 21-year-old organic sheep farmer, is said to be the biggest star of the project so far, uploading photos and videos of life on his family's farm; while a female minister in the Church of Sweden and a Bosnian immigrant have also posted on the feed. The Swedish Institute and VisitSweden launched the experiment in December, which has helped to double Sweden's Twitter followers in the past month."

An anonymous reader tips news that The Pirate Bay is making a move away from .torrent files in favor of 'magnet links.' On Thursday the site made magnet links the default, and TorrentFreak reports that they'll stop serving .torrent files altogether in about a month. "The announcement is bound to lead to confusion and uncertainty among many torrent users, but in reality very little will change for the average Pirate Bay visitor. Users will still be able to download files, but these will now be started through a magnet link instead of a .torrent file. The Pirate Bay team told TorrentFreak that one of the advantages of the transition to a 'magnet site' is that it requires relatively little bandwidth to host a proxy. This is topical, since this week courts in both Finland and the Netherlands ordered local Internet providers to block the torrent site. Perhaps even better, without the torrent files everyone can soon host a full copy of The Pirate Bay on a USB thumb drive, which may come in handy in the future."

PuceBaboon writes "It's worth noting that, in addition to the main FreeBSD release covered here recently, PC-BSD has also released their 'Isotope' edition, based on FreeBSD 9.0. Why would you be interested? Well, PC-BSD, while not the first, is certainly the most current version of FreeBSD aimed squarely at the desktop user. Pre-configured for the desktop and using a graphical installer, the 9.0 release includes KDE, GNOME, XFCE and LXDE desktop environments, an update manager, WiFi 'quick connect,' BootCamp support and auto-configuration for most common hardware. Live-CD, VirtualBox and VMware release images for 32- and 64-bit architectures also make it easier than ever for users to test the release before committing to a full install. Check out the torrents (scroll down), main download page and the PC-BSD 9.0 manual pages."

OverTheGeicoE writes "Recently, TSA's 'Blogger Bob' Burns posted a rant against a cupcake on the TSA blog. Perhaps it made you wonder if TSA and its parent agency, the Department of Homeland Security, really understand what we're saying about them, especially online. Well, thanks to a Freedom of Information Act lawsuit from the Electronic Privacy Information Center, we now know a lot more about how they monitor online comments aside from 'Blogger Bob.' EPIC has received hundreds of pages of documents regarding DHS's online surveillance program. These documents reveal that DHS has contracts with General Dynamics for '24/7 media and social network monitoring.' Perhaps it will warm your heart to know that DHS is particularly interested in tracking media stories that 'reflect adversely' on the U.S. government generally and DHS specifically. The documents include a report summary that might be representative of General Dynamics' work. The example includes summaries of comments on blogs and social networking sites, including quotes. Then again, you might remember J. Edgar Hoover's monitoring of antiwar activists during the Vietnam War, which certainly wasn't for the protesters' benefit."

ColdWetDog writes "The Dropbox file storage and synchronization service has managed to attract 50 million users and $250 million in venture capital. The founder of Dropbox, Drew Houston, says he is determined to build the next Google or Apple, not to sell out to them. Even for a guy whose paper valuation is around $600 million, it seems like the best he could hope for is another Facebook-level company — file storage isn't that sexy. I wish him luck in his bid to remain independent. I'd rather see Dropbox remain fairly agnostic with regard to other Internet services."

FatLittleMonkey writes "A new study on mice suggests damage caused by diseases like Multiple sclerosis, as well as natural aging, can be reversed by an infusion of stem cell rich blood from younger mice. Multiple sclerosis is a chronic inflammatory disease that erodes the fatty myelin sheaths around the axons of the brain and spinal cord, and can result in serious disability. Similar effects occur naturally with aging. From New Scientist: 'White blood cells called macrophages from the young mice gathered at the sites of myelin damage. Macrophages engulf and destroy pathogens and debris, including destroyed myelin. "We know this debris inhibits regeneration, so clearing it up is important," says team member Amy Wagers of Harvard University.' Here's the academic paper's abstract."

bonch writes "Author Susan Cain argues that modern society's focus on charisma and group brainstorming has harmed creativity and productivity by removing the quiet, creative process. 'Research strongly suggests that people are more creative when they enjoy privacy and freedom from interruption. And the most spectacularly creative people in many fields are often introverted, according to studies by the psychologists Mihaly Csikszentmihalyi and Gregory Feist. They're extroverted enough to exchange and advance ideas, but see themselves as independent and individualistic. They're not joiners by nature.'"

New submitter smithz writes "Bloomberg is reporting that the U.S. Federal Trade Commission is expanding its antitrust probe of Google Inc. to include scrutiny of its new Google+ social networking service. Google this week introduced changes to its search engine so that results feature photos, news and comments from Google+. The changes sparked a backlash from bloggers, privacy groups and competitors who said the inclusion of Google+ results unfairly promotes the company's products over other information on the Web. Before expanding the probe, FTC was already investigating Google for giving preference to its own services in search results and whether that practice violates antitrust laws. The agency is also examining whether the company is using its control of the Android mobile operating system to discourage smartphone makers from using rivals' applications. Google is facing similar investigations in Europe and South Korea."

eefsee writes "The White House today responded to two petitions with a statement titled 'Combating Online Piracy while Protecting an Open and Innovative Internet.' They note that 'We must avoid creating new cybersecurity risks or disrupting the underlying architecture of the Internet.' In particular, they cite manipulation of DNS as problematic. But overall the statement is clearly supportive of anti-piracy efforts and lays down this challenge: 'So, rather than just look at how legislation can be stopped, ask yourself: Where do we go from here? Don't limit your opinion to what's the wrong thing to do, ask yourself what's right.' So, what's right?"

An anonymous reader writes "So, it's that wonderful time of year again. Instead of buying the latest, greatest whiz-bang, overpriced fad toy of the year, I thought I might try my hand at corrupting my nieces (ages 12 and 14) in a nerdier direction with some sort of introductory robotics kit. They have no programming experience, and part of my idea is that it would be encouraging for them to see interactions of their code that they write with the real-world by being able to control some actuators and read sensors. The first thing that comes to mind is Lego Mindstorms, but I find them a bit on the pricey side of things. My budget falls between $40 and $100, and the ideal kit would focus more on the software side than on soldering together circuits. I'd be looking for a kit that provides an easy to learn API and development tools that will work with a standard Windows PC. I don't mind spending a few afternoons helping them out with the basics, but I'd like for them to be able to be able to explore on their own after grasping the initial concepts. Has anybody gotten their younger relations into programming through robotics, and what kits might you recommend?"

mikejuk writes "A recent Google research paper outlines how it might use AI to read digits in natural images — specifically Street View photos. The idea is to automatically extract the number of each house as captured by Street View and then use this to improve the geocoding data returned by Google. When you next ask for directions to a particular address the new data could be used to show you a street view looking directly at the house you specified."

Runaway1956 writes "Last month, philosopher Patrick Lin delivered this briefing about the ethics of drones at an event hosted by In-Q-Tel, the CIA's venture-capital arm. It's a thorough and unnerving survey of what it might mean for the intelligence service to deploy different kinds of robots. This story is very definitely not like Asimov's robotic laws! As fine a mind as Isaac Asimov had, his Robot stories seem a bit naive, in view of where we are headed with robotics."
