Take 300, 000 computer-controlled mirrors, each 7 feet high and 10 feet wide. Control them with computers to focus the Sun’s light to the top of 459-feet towers, where water is turned to steam to power turbines. Bingo: you have the world’s biggest solar power plant, the Ivanpah Solar Electric Generating System . Read more…

Lawrence Livermore National Laboratroy Researchers in the US have overcome a key barrier to making nuclear fusion reactors a reality. In results published in Nature , scientists have shown that they can now produce more energy than the fuel put into an experiment. The use of fusion as a source of energy remains a long way off, but the latest development is an important step toward that goal. Nuclear fusion is the process that powers the sun and billions of other stars in the universe. If mastered, it could provide an unlimited source of clean energy because the raw materials are plentiful and the operation produces no carbon emissions. During the fusion process, smaller atoms fuse into larger ones releasing huge amounts of energy. To achieve this on Earth, scientists have to create conditions similar to those at the center of the sun. This involves creating very high pressures and temperatures.

Giant leap for nuclear fusion as scientists get more energy out than fuel put in
In the modern responsive Web Three Point Oh Internet, Slashdot stands like a thing frozen in time—it’s a coelacanth stuck incongruously in an aquarium full of more colorful fish. The technology news aggregator site has been around since 1997, making it positively ancient as websites are reckoned. More importantly, Slashdot’s long focus on open source technology news and topics has caused it to accrete a user base that tends to be extremely technical, extremely skilled, and extremely opinionated. That user base is itself the main reason why Slashdot continues to thrive, even as its throwback interface makes it look to untrained eyes like a dated relic. Though the site is frequently a source of deep and rich commentary on topics, the barrier for new users to engage in the site’s discussions is relatively high—certainly higher than, say, reddit (or even Ars). This doesn’t cause much concern to the average Slashdot user, but tech job listing site Dice.com (which bought Slashdot in September 2012, along with Sourceforge and a number of other digital properties) appears to have decided it’s time to drag Slashdot’s interface into the 21st century in order to make things comfortable for everyone—old and new users alike. And the Slashdot user base is not pleased. Read 16 remaining paragraphs | Comments

Slashdot’s new interface could kill what keeps Slashdot relevant
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.

Graphene Conducts Electricity Ten Times Better Than Expected
Aurich Lawson Silk Road, the infamous and anonymous online marketplace specializing in illicit goods, sells everything from pot to black tar heroin. If you can smoke it, inject it, or snort it, there’s a good chance Silk Road has it. Well, had it. Late last year, the FBI burst into a local branch of the San Francisco Public Library and arrested one Ross Ulbricht, the alleged kingpin who ran the site. It all happened while Ulbricht’s laptop was open and he was logged into his encrypted accounts. In the days that followed, the feds dropped a host of charges on Ulbricht, including several salacious accusations that Ulbricht attempted to arrange hits on various people he thought had betrayed him or blackmailed him. The feds also arrested several people accused of being major sellers, creating anxiety for those who ever bought or sold on the site. The Silk Road was closed . It didn’t take long to return. Just as the previous Silk Road operator had done, the new owner called himself “Dread Pirate Roberts” (DPR). The name came from a character in The Princess Bride who passes his piratical business down from one individual to the next, each of whom uses the same name to ensure continuity. So in a move that would seem to tempt fate, the new DPR built another version of Silk Road and restarted the drug marketplace. Read 42 remaining paragraphs | Comments

Google engineers have added a new feature to the Chrome browser that automatically warns users when browsing settings have been altered by malicious software. The new protection was unveiled in a blog post published Friday by Linus Upson, Google’s vice president of engineering. It is designed to augment a feature introduced in October that allows users to return Chrome settings to a factory-fresh state with the click of a single button. Malicious code frequently included with screensavers and other free software can surreptitiously make any number of changes to Chrome settings. Injecting ads into webpages and blocking the ability to revert settings to those previously chosen by the user are two of the more common ways unscrupulous developers tamper with browser options. The hijackings were among the top issue users reported in Chrome help forums when the reset button was introduced in October. Upson explained: Read 1 remaining paragraphs | Comments

Corona del Mar sits on an idyllic part of the Orange County coastline. Mark Weston A hacking scandal involving keyloggers and electronic grade-changing at a high school in Newport Beach, a well-to-do area of Southern California, has resulted in the expulsion of 11 students. The Orange County Register reported Wednesday that six of those students had already left the district, but five had been transferred to another local school. “The Board’s action imposes discipline upon these students for the maximum allowed by the Education Code for what occurred at Corona del Mar High School,” Laura Boss, the Newport Mesa Unified School District spokesperson wrote in a statement on Wednesday. US News and World Report ranked the high school in question as the 46 th best within California. Read 23 remaining paragraphs | Comments

Amazon has just reported its earnings for the fourth quarter of 2013 . According to The Verge , Amazon CFO Tom Szkutak mentioned that the company is considering a price increase for its Amazon Prime customers in the US. The decision hasn’t been made, but high shipping costs could prompt a price increase of between $20 and $40 a year for the service. Prime began life as a service that offered free two-day shipping on many items for a flat, $79-a-year fee. As Amazon has branched out into tablets and streaming media, perks like the Instant Video service and Kindle Owners’ Lending Library have been added to sweeten the deal. The potential price increase would be the first since Prime was introduced in the US in 2005. Amazon reported income of $239 million on sales of $25.59 billion for the fourth quarter of 2013, lower than analysts had expected. The company’s guidance for the first quarter of 2014 projects sales between $18.2 and $19.9 billion and expects income to be somewhere between a profit of $200 million and a loss of $200 million.
