Graphene Conducts Electricity Ten Times Better Than Expected

ananyo writes “Physicists have produced nanoribbons of graphene — the single-atom-thick carbon — that conduct electrons better than theory predicted even for the most idealized form of the material (abstract). The finding could help graphene realize its promise in high-end electronics, where researchers have long hoped it could outperform traditional materials such as silicon. In graphene, electrons can move faster than in any other material at room temperature. But techniques that cut sheets of graphene into the narrow ribbons needed to form wires of a nano-scale circuit leave ragged edges, which disrupt the electron flow. Now a team led by physicist Walt de Heer at the Georgia Institute of Technology in Atlanta has made ribbons that conduct electric charges for more than 10 micrometres without meeting resistance — 1, 000 times farther than in typical graphene nanoribbons. The ribbons made by de Heer’s team in fact conduct electrons ten times better than standard theories of electron transport they should, say the authors.” Read more of this story at Slashdot.

​Why a Single-Molecule LED Could Be a Big Deal

Technologically speaking, smaller is virtually always better. So it’s perhaps no surprise that scientists have developed the first ever single-molecule LED . But why is it potentially such a big deal? Read more…

Audience Jeers Contestant Who Uses Game Theory To Win At ‘Jeopardy’

Hugh Pickens DOT Com writes “USA Today reports that Arthur Chu, an insurance compliance analyst and aspiring actor, has won $102, 800 in four Jeopardy! appearances using a strategy — jumping around the board instead of running categories straight down, betting odd amounts on Daily Doubles and doing a final wager to tie — that has fans calling him a ‘villain’ and ‘smug.’ Arthur’s in-game strategy of searching for the Daily Double that has made him such a target. Typically, contestants choose a single category and progressively move from the lowest amount up to the highest, giving viewers an easy-to-understand escalation of difficulty. But Arthur has his sights solely set on finding those hidden Daily Doubles, which are usually located on the three highest-paying rungs in the categories (the category itself is random). That means, rather than building up in difficulty, he begins at the most difficult questions. Once the two most difficult questions have been taken off the board in one column, he quickly jumps to another category. It’s a grating experience for the viewer, who isn’t given enough to time to get in a rhythm or fully comprehend the new subject area. ‘The more unpredictable you are, the more you put your opponents off-balance, the longer you can keep an initial advantage, ‘ says Chu. ‘It greatly increases your chance of winning the game if you can pull it off, and I saw no reason not to do it.’ Another contra-intuitive move Chu has made is playing for a tie rather than to win in ‘Final Jeopardy’ because that allows you advance to the next round which is the most important thing, not the amount of money you win in one game. ‘In terms of influence on the game, Arthur looks like a trendsetter of things to come, ‘ says Eric Levenson. ‘Hopefully that has more to do with his game theory than with his aggressive button-pressing.'” Read more of this story at Slashdot.

Firefox 27 Released: TLS 1.2 Support, SPDY 3.1, SocialAPI Improvements

jones_supa writes “Mozilla has released Firefox 27 for Linux, Android, Mac, and Windows (download). One of the big changes is enabling support for TLS 1.1 and 1.2 by default. Firefox 27 also supports the SPDY 3.1 protocol. Developers got some new toys: support was added for ES6 generators in SpiderMonkey, the debugger will de-obfuscate JavaScript, and style sheets can be reset by using all:unset. Mozilla also announced some new social integration options. In addition to all these changes, the Android version got some UI improvements and font readability upgrades. For a future release, Mozilla is currently testing a new approach for Firefox Sync in Nightly builds. They recognized the headaches involved with how it works, and they’re now opting to use a simple e-mail and password combination like Google Chrome does. In the old system, users were forced to store an auto-generated authorization code, which, if lost, would render their bookmarks, passwords and browsing history inaccessible. ” Read more of this story at Slashdot.

Will Microsoft IIS Overtake Apache?

First time accepted submitter jcdr writes “February’s 2014 Web Server Survey by Netcraft shows a massive increase [in the share of] Microsoft’s web server since 2013. Microsoft’s market share is now only 5.4 percentage points lower than Apache’s, which is the closest it has ever been. If recent trends continue, Microsoft could overtake Apache within the next few months, ending Apache’s 17+ year reign as the most common web server.” Read more of this story at Slashdot.

HealthCare.gov Can’t Handle Appeals of Errors

PapayaSF writes “The Washington Post reports that roughly 22, 000 people have claimed they were charged too much, steered into the wrong insurance program, or denied coverage, but the HealthCare.gov website cannot handle appeals. They’ve filled out seven-page forms and mailed them to a federal contractor’s office in Kentucky, where they were scanned and entered, but workers at CMS cannot read them because that part of the system has not been built. Other missing aspects are said to have higher priorities: completing the electronic payment system for insurers, the connections with state Medicaid programs, and the ability to adjust coverage to accommodate major changes such as new babies. People with complaints about mistakes have been told to ‘return to the Web site and start over.'” Read more of this story at Slashdot.

Press Used To Print Millions of US Banknotes Seized In Quebec

An anonymous reader writes “The Canadian Royal Mounted Police report: An offset printing press used to manufacture counterfeit $20 banknotes was seized by the RCMP and US Secret Service. This significant seizure was made earlier today in the Trois-Rivières area. The authorities had been looking for this offset press for several years. A large quantity of paper was also seized by police, that could have been used by the counterfeiters to manufacture from $40-$200 million. The very high quality counterfeit notes were virtually undetectable to the naked eye. Some of the features they had were uncommon, including the type of paper used, which was especially made with a Jackson watermark and a dark vertical stripe imitating the security thread found in authentic notes.” Read more of this story at Slashdot.

Archaeologists Uncover 300,000-Year-Old Kitchen in Israeli Cave

Sure, early hominins used fire for upwards of a million years. But when did early hominins start acting like humans—for example, cooking in the same spot each night? The new discovery of an old ( really old) hearth at an Israeli dig site could hold the answer. Read more…

World’s First Multi-Color, Multi-Polymer 3D Printer Unveiled

Lucas123 writes “Stratysis today announced it will be shipping this year a printer that can use hundreds of colors and polymers to create production-grade or prototype objects without the need for assembly. Previously, manufacturers could print multi-colored parts using many different materials and assemble them after completion. Stratasis’ Objet500 Connex3 Color Multi-material 3D Printer features a triple-jet printer head that combines droplets of three base materials to produce parts with virtually unlimited combinations of rigid, flexible and transparent color materials in a single print run.” Read more of this story at Slashdot.

$499 3-D Printer Drew Plenty of Attention at CES (Video)

3-D printing is far from new, but a $499 3-D printer is new enough to get a bunch of people to write about it, including someone whose headline read, CES 2014: Could 3D printing change the world? XYZPrinting, the company behind the da Vinci 1.0 printer, has some happy-looking executives in the wake of CES. They won an award, and their booth got lots of attention. This is what trade shows are all about for small and/or new companies. Now the XYZ Printing people can go home and pump out some product — assuming they got a lot of orders (and not just attention) at CES. Read more of this story at Slashdot.
