Submission + - Scientists report first solar cell producing more (physorg.com)

Fireking300 writes: A paper on the breakthrough appears in the Dec. 16 issue of Science Magazine. Titled “Peak External Photocurrent Quantum Efficiency Exceeding 100 percent via MEG in a Quantum Dot Solar Cell,” it is co-authored by NREL scientists Octavi E. Semonin, Joseph M. Luther, Sukgeun Choi, Hsiang-Yu Chen, Jianbo Gao, Arthur J. Nozikand Matthew C. Beard. The research was supported by the Center for Advanced Solar Photophysics, an Energy Frontier Research Center funded by the DOE Office of Science, Office of Basic Energy Sciences. Semonin and Nozik are also affiliated with the University of Colorado at Boulder.
The researchers achieved the 114 percent external quantum efficiency with a layered cell consisting of antireflection-coated glass with a thin layer of a transparent conductor, a nanostructured zinc oxide layer, a quantum dot layer of lead selenide treated with ethanedithol and hydrazine, and a thin layer of gold for the top electrode.


LulzSec Announces That It Is Done 412

MaxBooger writes "LulzSec, the notorious hacker group that's been on a rampage, just announced that it's disbanding. This follows 50 days' chaos during which time it took down several websites (including CIA.gov at one point), exposed passwords, exposed documents of the Arizona penal system, and at one point threatened to hit Too Big To Fail banks. Obviously, it's possible that the group will not abide by its promise to quit. Nobody knows."

Submission + - Google.com missing closing HTML tags? Standards? (w3.org)

yosofun writes: From a quick viewsource, any casual user can easily see that Google.com is missing the closing HTML and BODY tags (Load up the page. View Source. Use the Find feature in your browser, and search for "</html>" or "</body>"). Why?

W3C Validator shows 35 errors and 2 warnings for google.com. Similar validation crawls for Microsoft.com, Apple.com, Yahoo.com show errors as well. There are web designers who would strive inhuman hours to achieve standards-compliant perfection, and yet the trend with the sites visited most by folks on the Internet is to ignore standards. What does this mean — are standards worth all that prissiness?


Brazil Forbids DRM On the Public Domain 258

nunojsilva writes "Cory Doctorow reports that the Brazilian equivalent of DMCA explicitly forbids using DRM-like techniques on works in the public domain. 'Brazil has just created the best-ever implementation of WCT [WIPO Copyright Treaty]. In Brazil's version of the law, you can break DRM without breaking the law, provided you're not also committing a copyright violation.' This means that, unlike the US, where it is illegal to break DRM, in Brazil it is illegal to break the public domain."

What Developers Think About Apple's iAd 263

Nemilar writes "It's been about a week since Apple rolled out its new advertising platform, and developers of iPhone apps are watching the earliest returns to see how much money they can expect to make from these ads. One developer reported Thursday that he earned $1,400 in one day for his flashlight app. The amount iAds pay is 'a high number when you get it, but you don't get it very often,' said Dave Yonamine, the director of marketing at MobilityWare. The article discusses revenue potential in relation to the only other mobile ads platform, AdMob for Android, and claims that iAd paid as much as $148 for the same number of ads as $1 on AdMob; but this extreme ratio is likely to erode as the novelty wears off."

REMnux, the Malware Analysis Linux OS 58

Trailrunner7 writes "A security expert has released a stripped-down Ubuntu distribution designed specifically for reverse-engineering malware. The OS, called REMnux, includes a slew of popular malware-analysis, network monitoring and memory forensics tools that comprise a very powerful environment for taking apart malicious code. REMnux is the creation of Lenny Zeltser, an expert on malware reverse engineering who teaches a popular course on the topic at SANS conferences. He put the operating system together after years of having students ask him which tools to use and what works best. He originally used Red Hat Linux, but recently decided that Ubuntu was a better fit. REMnux has three separate tools for analyzing Flash-specific malware, including SWFtools, Flasm and Flare, as well as several applications for analyzing malicious PDFs, including Didier Stevens' analysis tools. REMnux also has a number of tools for de-obfuscating JavaScript, including Rhino debugger, a version of Firefox with NoScript, JavaScript Deobfuscator and Firebug installed, and Windows Script Decoder."
