Cosmic Radiation Makes Trees Grow Faster 162

Posted by kdawson from the ents-are-going-to-war dept.
Diamonddavej writes "The BBC reports that researchers at the University of Edinburgh have found that Galactic Cosmic Rays (GCRs) somehow makes trees grow faster. GCRs vary according to the 11-year solar cycle, with more GCRs hitting the Earth during solar minimum when there is a lull in the solar wind, which normally acts to protect the inner solar system from external galactic radiation. The mechanism might have something to do with GCRs increasing cloud cover, which diffuses sunlight and increases the efficiency of photosynthesis. Nevertheless, the researchers remain mystified and are requesting further ideas and research collaboration to test hypotheses. (How about Radiation Hormesis, AKA 'Vitamin-R?')" Here is the paper's abstract at the journal New Phytologist. The researchers say: "The relation of the rings to the solar cycle was much stronger than to any climatological factors. ... As for the mechanism, we are puzzled."

Ministry of Defense's "How To Stop Leaks" Document Is Leaked 141

Posted by samzenpus from the there's-no-fighting-in-the-war-room dept.
samzenpus writes "A restricted 2,400 page-document put out by the MoD designed to help intelligence personnel with information security has been leaked onto the internet. Wikileaks notes that Joint Services Protocol 440 (JSP 440), was published in 2001 and lays out protocols to defend against hackers, journalists, and foreign spies. it says, 'Leaks usually take the form of reports in the public media which appear to involve the unauthorized disclosure of official information (whether protectively marked or not) that causes political harm or embarrassment to either the UK Government or the Department concerned... The threat [of leakage] is less likely to arise from positive acts of counter-espionage, than from leakage of information through disaffected members of staff, or as a result of the attentions of an investigative journalist, or simply by accident or carelessness.' " Looks like it's time to write JSP 441.

Open Access To Exercise Data? 188

Posted by kdawson from the lub-dub dept.
identity0 writes "A recent Slashdot discussion about heart-rate monitors in schools got me thinking about getting one for my own exercise. It turns out that the available models have a wide range of features: calorie rate, pedometers, GPS, PC connectivity, etc. Being a geek, I want one that will let me look at my exercise data, and I'm curious what experiences Slashdotters have had with them. Some download data to a proprietary application — are open source alternatives available or is the data format easily readable? Others upload data to an online app — can the data be pulled off the site or is it forever trapped on their servers? While I'm not an open source zealot or a paranoid about my data being shared, I would like to know that I can access my data in the future. Whatever method you guys use to monitor your exercise, I'd love to hear about it."

Jack Kirby Heirs Reclaim Marvel/Disney Rights 380

Posted by kdawson from the more-movies-for-grownups dept.
lbalbalba writes "Heirs to comic book legend Jack Kirby sent 45 notices of copyright termination to Marvel Entertainment, prospective Marvel buyer Disney, Sony Pictures, Universal Pictures, 20th Century Fox, Paramount Pictures, and others studios that that hold licensed media rights to Marvel characters. Some rights could revert to the heirs as soon as 2014, for characters that are among the hottest in Hollywood: The Incredible Hulk, The Mighty Thor, Iron Man, Spider-Man, The Avengers, and others. Among other things the heirs' demand could cause problems for Disney's as yet unconsummated purchase of Marvel."

US Government Sets Up Online "App Store" 138

Posted by samzenpus from the top-25-free-programs dept.
krapper writes "The Obama administration has unveiled a government 'app store' designed to push the federal bureaucracy into the era of cloud computing. The change means some federal employees will begin using services like YouTube, Gmail and WordPress, which store data on private internet servers instead of on those paid for with public money. The process will start small but will ramp up quickly, Vivek Kundra, the US chief information officer, said in a blog post on Tuesday. 'Our policies lag behind new trends, causing unnecessary restrictions on the use of new technology,' Kundra writes in the post on WhiteHouse.gov. 'We are dedicated to addressing these barriers and to improving the way government leverages new technology.' The app store is designed for federal employees doing official government business and is not intended for use by the public."

Has the WebOS Finally Arrived? 227

Posted by timothy from the alien-craft-constructed-entirely-of-buzzwords dept.
SphereOfInfluence writes "Dion Hinchcliffe over on ZDNet declared in a new post that the Web OS has finally arrived and that businesses and IT departments must adjust to the fact that everything's starting to move to the cloud. He cites John Hagel's so-called big business shifts of the 21st century and claims cloud computing, crowdsourcing, open APIs, Software-as-a-Service are the future of the workplace. He goes on to present a compelling visual model of the Web OS circa 2009 and examples to back up some of the statements."

Schooling, Homeschooling, and Now, "Unschooling" 1345

Posted by ScuttleMonkey from the everything-i-need-to-know-i-learned-from-quake dept.
ciaohound writes "The Baltimore Sun has a story about 'unschooling,' which is like homeschooling except, well, without the schooling. '...unschooling incorporates every facet of a child's life into the education process, allowing a child to follow his passions and learn at his own pace, year-round. And it assumes that an outing at the park — or even hours spent playing a video game — can be just as valuable a teaching resource as Hooked on Phonics.' If you have ever been forced to sit in a classroom where no learning was taking place, you may understand the appeal. A driving force behind the movement is parents' dissatisfaction with regular schools, and presumably with homeschooling as well. Yet few researchers are even aware of unschooling and little research exists on its effectiveness. Any Slashdotters who have experience with 'unschooling?'"

Intel's Braidwood Could Crush SSD Market 271

Posted by kdawson from the if-only-they-could-make-it-rotate dept.
Lucas123 writes "Intel is planning to launch its native flash memory module, code named Braidwood, in the first or second quarter of 2010. The inexpensive NAND flash will reside directly on a computer's motherboard as cache for all I/O and it will offer performance increases and other benefits similar to that of adding a solid-state disk drive to the system. A new report states that by achieving SSD performance without the high cost, Braidwood will essentially erode the SSD market, which, ironically, includes Intel's two popular SSD models. 'Intel has got a very good [SSD] product. But, they view additional layers of NAND technology in PCs as inevitable. They don't think SSDs are likely to take over 100% of the PC market, but they do think Braidwood could find itself in 100% of PCs,' the report's author said."

Wireless Power Consortium Pushes for "Qi" Standard 189

Posted by ScuttleMonkey from the someone-call-apple dept.
The Wireless Power Consortium (comprised of Samsung, Sanyo, Olympus, Philips, Texas Instruments, and others) has started a push towards a wireless charging standard under the moniker "Qi" (pronounced "chee"). "Members of the Wireless Power Consortium are reviewing version 0.95 of its technical specification which defines a proposed standard for charging devices, using up to 5Watts power, delivered by electromagnetic induction. The spec could evolve into a standard — and will be demonstrated by multiple vendors on September 15th to 16th. ... It is less ambitious than the system demonstrated this summer by Witricity, which operates at a distance of a few meters, using resonance, which the company claims has green benefits through replacing disposable batteries."

Surface Plume On Betelgeuse Imaged 51

Posted by Soulskill from the it-looks-hungry dept.
BJ_Covert_Action writes "Astronomy Now is running a piece regarding some new, exquisitely detailed pictures taken of Betelgeuse, a star in the constellation Orion. Betelgeuse is classified as a supergiant star, and its diameter is approximately 1,000 times that of the sun. Two teams of astronomers used ESO's 'Very large Telescope,' its NACO instruments, and an imaging technique known as 'Lucky Imaging' to take some of the most detailed pictures of Betelgeuse to date. The new pictures reveal a gas plume on Betelgeuse which extends from the surface of the star a distance greater than that between our sun and Neptune. The images also show several other 'boiling' spots on the surface of Betelgeuse, revealing the surface to be quite tumultuous. Currently, it is known that stars of Betelgeuse's size eject the equivalent mass of the Earth into space every year. This recent astronomy work will help researchers determine the mechanics behind such ejections." Update — 8/05 at 13:31 by SS: Here's the original press release from the European Southern Observatory, since the Astronomy Now page has slowed to a crawl.

Expedition To Explore an Alaska-Sized Plastic "Island" 325

Posted by kdawson from the one-hundred-megatons dept.
Peace Corps Online writes "An expedition called Project Kaisei has departed bound for the Great Pacific Garbage Patch — a huge 'island' of plastic debris in the Pacific Ocean estimated to be the size of Alaska (some estimates place it at ten times that size). The expedition will study the impact of the waste on marine life, and research methods to clean up the vast human-created mess in the Pacific. The BBC quotes Ryan Yerkey, the project's chief of operations: 'Every piece of trash that is left on a beach or ends up in our rivers or estuaries and washes out to the sea is an addition to the problem, so we need people to be the solution.' The garbage patch occupies a large and relatively stationary region of the North Pacific Ocean bound by the North Pacific Gyre, a remote area commonly referred to as the horse latitudes. The rotational pattern created by the North Pacific Gyre draws in waste material from across the North Pacific Ocean, including the coastal waters off North America and Japan. As material is captured in the currents, wind-driven surface currents gradually move floating debris toward the center, trapping it in the region. 'You are talking about quite a bit of marine debris but it's not a solid mass,' says Yerkey. 'Twenty years from now we can't be harvesting the ocean for trash. We need to get it out but we need to also have people make those changes in their lives to stop the problem from growing and hopefully reverse the course.'"

Can We Abandon Confidentiality For Google Apps? 480

Posted by kdawson from the what-price-convenience dept.
An anonymous reader writes "I provide IT services for medium-sized medical and law practices. Lately I have been getting a lot of feedback from doctors and lawyers who use gmail at home and believe that they can run a significant portion of their practice IT on Google Apps. From a support standpoint, I'd be happy to chuck mail/calendar service management into the bin and let them run with gmail, but for these businesses, there is significant legal liability associated with the confidentiality of their communications and records (e.g., HIPAA). For those with high-profile celebrity clients, simply telling them 'Google employees can read your stuff' will usually end the conversation right there. But for smaller practices, I often get a lot of push-back in the form of 'What's wrong with trusting Google?' and 'Google's not interested in our email/calendar.' Weighing what they see as a tiny legal risk against the promise of Free IT Stuff(TM) becomes increasingly lopsided given the clear functionality / usability / ubiquity that they experience when using Google at home. So my question to the Slashdot community is: Are they right? Is it time for me to remove the Tin Foil Hat on the subject of confidentiality and stop resisting the juggernaut that is Google? If not, what is the best way to clarify the confidentiality issues for these clients?"

New Map Hints At Venus' Wet, Volcanic Past 118

Posted by timothy from the now-a-respectable-middle-class-planet dept.
Matt_dk writes with this excerpt from Space Fellowship: "Venus Express has charted the first map of Venus' southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with a plate tectonics system and an ocean of water. The map comprises over a thousand individual images, recorded between May 2006 and December 2007. Because Venus is covered in clouds, normal cameras cannot see the surface, but Venus Express used a particular infrared wavelength that can see through them."

RIAA Seeks Web Removal of Courtroom Audio 138

Posted by ScuttleMonkey from the afraid-people-might-see-what-they-are-up-to dept.
suraj.sun writes to tell us that the RIAA has asked a federal judge to order the removal of what they are calling "unauthorized and illegal recordings" by Harvard University's Charles Nesson of pretrial hearings and depositions in a file-sharing lawsuit. "The case concerns former Boston University student Joel Tenenbaum, who Nesson is defending in an RIAA civil lawsuit accusing him of file-sharing copyrighted music. Jury selection is scheduled in three weeks, in what is shaping up to be the RIAA's second of about 30,000 cases against individuals to reach trial. The labels, represented by the RIAA, on Monday cited a series of examples in which they accuse Nesson of violating court orders and privacy laws by posting audio to his blog or to the Berkman site."

Computer Reveals Stone Tablet "Handwriting" 42

Posted by timothy from the so-who-was-this-rosetta-guy-anyhow dept.
ewenc writes "A computer technique can tell the difference between ancient Greek inscriptions created by different artisans, a feat that ordinarily consumes years of human scholarship, reports New Scientist. A team of Greek computer scientists created the program after a scholar challenged them to attribute 24 inscriptions to their rightful cutter. The researchers scanned the tablets and constructed an average shape for several Greek letters in every tablet. After comparing the average letters between different tablets, they correctly attributed the inscriptions to six stone-cutters."
