Fysiks Wurks found on the U.S. Department of Energy website news of a breakthrough in solar energy efficiency. From the article: "...with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance." A page linked from Wikipedia's article on solar energy calculates the land area that would need to be covered by solar collectors at 8% efficiency to meet the world's energy needs (using 2003 figures). At 40% efficiency, it looks like a square 265 miles on a side in the American southwest would do it.

jrieth50 noted that a method of using geometric shapes combined with color to store up to 256GB of data on a sheet of paper or plastic. The article says "Files such as text, images, sounds and video clips are encoded in 'rainbow format' as colored circles, triangles, squares and so on, and printed as dense graphics on paper at a density of 2.7GB per square inch. The paper can then be read through a specially developed scanner and the contents decoded into their original digital format and viewed or played."

eldavojohn writes "The Washington Post is reporting that businesses are split on the current situation with patents in the United States. From the article: 'The court is scheduled to hear arguments Tuesday on what's obvious when older inventions are combined to create something new. The law says an invention that's "obvious" isn't patentable, but the definition isn't clear despite decades of litigation. The ambiguity, critics say, has led to an explosion of patents as companies stake claims on everything in sight, from strategies for avoiding taxes to golf ball designs. The result has been extensive and costly legal wrangling as companies of all sizes fight over who's infringing what. In some cases, small companies acquire patents not to develop new products but to sue for a quick windfall.' This sounds like some common criticism of the patent system that often pops up on Slashdot. The last part of the article mentions that most legal experts are expecting some changes to come of this. Hopefully soon we'll see some changes to the patent system for a better concept of intellectual property."

Alien54 writes "ESA's Mars Express has obtained images of the Cydonia region, site of the famous 'Face on Mars.' using the High Resolution Stereo Camera. After multiple attempts to image the Cydonia region from April 2004 until July 2006 were frustrated by altitude and atmospheric dust and haze, the High Resolution Stereo Camera (HRSC) on board Mars Express finally obtained, on 22 July, a series of images that show the famous 'face' on Mars in unprecedented detail, with a ground resolution of approximately 13.7 metres per pixel."

savio13 writes "The EFF has asked the US Supreme Court to overturn a patent law ruling that could pose a serious threat to Free and Open Source Software projects. A recent Federal Circuit Court of Appeals decision required that even the most obvious incremental advances can be patented unless it can be proved that someone else suggested it prior to the patent being filed. As such, many 'bad patents' are being used as roadblocks for legitimate innovators, especially those working for FOSS projects (who have better things to do then search through thousands of technical papers for some mention of the obvious). The full brief is available online in PDF format."

Asklepius M.D. writes "According to the Washington Post, France is contemplating legislation designed to 'to force compatibility between digital songs and the different machines that play them.' Known colloquially as the 'iPod bill', it is opposed by Apple, the Business Software Alliance, and others who refer to it as 'state-sponsored piracy.' Two versions of the bill have already passed France's Senate and National Assembly. From the article: 'Under the proposed law, Apple Computer Inc., Sony Corp., Dell Inc. and other companies could have to reveal trade secrets of their software so that their songs can play on competitors' devices.'"

fistfullast33l writes "Groklaw has reported that the USPTO has ruled the broadest claims of the JPEG Patent held by Fogent to be invalid. PUBPAT, the organization that requested the review, released the news earlier today. According to PJ, the ruling will be hard to overturn as the 'submitters knew about the prior art but failed to tell the USPTO about it.'"

KantIsDead writes "MIT's Tech Review is running an interview with Boston University Bioengineer Tim Gardner about the possibility of using bacteria to produce electricity. If fuel cells running off sugar are nearly here, alcohol-powered robots cannot be far." From the article: "While typical fuel cells use hydrogen as fuel, separating out electrons to create electricity, bacteria can use a wide variety of nutrients as fuel. Some species, such as Shewanella oneidensis and Rhodoferax ferrireducens, turn these nutrients directly into electrons. Indeed, scientists have already created experimental microbial fuel cells that can run off glucose and sewage. Although these microscopic organisms are remarkably efficient at producing energy, they don't make enough of it for practical applications."

qeorqe writes "The Robot Hall of Fame 2006 inductees have been announced! The induction ceremony will be at the RoboBusiness Conference in Pittsburgh on June 21. Anthony Daniels portrayer of C3PO, will be master of ceremonies. The selected robots are: AIBO, SCARA, David (A.I.), Gort (The Day the Earth Stood Still), and Maria (Metropolis). The announcement was made in conjunction with the 50th anniversary celebration of the computer science department at CMU (formerly CIT)."

Richard Gray writes "Should Linux accept proprietary video/graphics drivers from likes of Nvidia and ATI ? The GPL written by FSF says that the license prohibits proprietary drivers. From the article: 'To write open-source graphics drivers without help from Nvidia or ATI is tough. Efforts to reverse-engineer open-source equivalents often are months behind and produce only 'rudimentary' drivers, said Michael Larabel, founder of a high-end Linux hardware site Phoronix ... Torvalds has argued that some proprietary modules should be permissible because they're not derived from the Linux kernel, but were originally designed to work with other operating systems.' The FSF however, sharply disagrees. 'If the kernel were pure GPL in its license terms...you couldn't link proprietary video drivers into it, whether dynamically or statically.' Where do you fall on this issue?"

1up reports that Shigeru Miyamoto has, almost offhandedly, confirmed that the upcoming Zelda title will utilize the Revolution's wand functionality. From the article: "When asked about Twilight Princess' progress, Miyamoto said everything coming along well, and that 'because Revolution can run GameCube software, when you play Twilight Princess on Revolution you can take advantage of the Revolution controller.' Whoa, whoa, whoa. Stop the train. We already knew Twilight Princess would be playable on GameCube, but it's mighty odd for Miyamoto to simply announce such a feature on a whim - but apparently he has. Not only that, but Miyamoto made sure to underscore that 'almost everything' about Revolution will be revealed at E3 in May."

An anonymous reader writes "NetworkWorld is reporting that Indiana University Informatics researchers have created a site that highlights the differences in query results provided by country-specific search engines. cenSEARCHip looks at engines like the versions of Google and Yahoo built to accommodate free-speech restrictions in China, Germany and France."

smooth wombat writes "A committee of the National Academy of Sciences, headed by Richard Anthens, has warned that 'the vitality of Earth science and application programs has been placed at substantial risk by a rapidly shrinking budget.' The list of Earth-observing satellite programs affected is a long one and includes satellite programs which observe nearly every aspect of Earth's climate. A delay in launching a replacement satellite or the disabling of a current satellite without a replacement could mean that data necessary to monitor or predict an upcoming event would be severely restricted. For its part NASA says that tight budgets force it to cut funding for all but the most vital programs. 'We simply cannot afford all of the missions that our scientific constituencies would like us to sponsor,' NASA administrator Michael Griffin told members of Congress when he testified before the House Science Committee February 16."
