drag2share: MIT reactor gets a second shot at producing unlimited clean energy

Nuclear fusion is the holy grail of scientists (and politicians) as it could produce limitless free energy without nasty consequences like meltdowns and radioactive waste. Though nobody's been able to build a reactor that produces more energy than it consumes (except arguably one time), scientists are still trying, with three experimental reactors currently in operation in the US. One of those, however, has been in the Obama administration's cross-hairs: MIT's Alcator C-Mod reactor. The White House decided to chop that program back in 2012, calling it too small, outdated and a vanity program for MIT, according to the Boston Globe.

Instead, the White House wanted to divert funds to the promising ITER tokamek fusion reactor. Though located in France, US researchers would have a direct line to the massive project, which aims to help transition fusion from the experimental phase to a practical reactor. Once MIT found out that its own reactor would be cut, however, it mobilized its lobbying arm, and convinced local congressman Michael Capuano that it was worth saving. He recruited a group including Senator Elizabeth Warren, which pitched other other representatives on the merits of the project. They emphasized the patriotic angle by showing a map with hundreds of subcontractors in 47 of 50 states which supplied the project.

In the end, the Senate decided to throw $22 million MIT's way to keep the project alive until 2016, while chopping ITER funding by $25 million. One skeptic pointed out that such funds would be used by MIT for a five week experiment by 12 graduate students. "This would be $1.5 million per student." Still, the reactor has now been re-started with a ceremonial button push by Senator Warren -- check out the entire saga at the Globe right here.

drag2share: Nano barcodes can trace bombs even after they've exploded

Nanoparticle barcode results on jars

You may not pay much notice to product trackers like barcodes and RFID tags, but they're absolutely vital in some fields; they cut back on bootlegging and help police determine the origins of bombs. Worcester Polytechnic Institute may have just delivered a major breakthrough, then, by developing nanoparticle barcodes. The minuscule tracers identify an object by producing a unique thermal signature (those colored lines you see in the photo) when they reach their melting point. As they don't participate in any chemical reaction, you can integrate them into any item and get a positive ID whenever you like, even if you're dealing with exploded TNT.

The substance would most likely be used to stop counterfeiters, thieves and other shady dealers by making it impossible to erase evidence without destroying any ill-gotten goods. However, the technology might be particularly handy for fighting terrorism. Investigators could easily pinpoint the suppliers of not just explosives, but the chemicals used to make explosives -- they could identify the manufacturer (and even the individual store) for the fertilizer in a homemade bomb. The scientists' stealthy barcodes are a long way from reaching store shelves, if they do at all, but there could be a day when it's possible to trace virtually any high-value product.

A Computer Has Passed the Turing Test For the First Time

This is big. A computer has successfully managed to fool a bunch of researchers into thinking that it was a 13-year-old boy named Eugene Goostman. In doing so, it has become the first computer in the world to have successfully passed the Turing Test.

New film makes shatterproof phone screens a practical possibility

Shattered iPhone 4 screen

Sure, the screen on your smartphone is likely scratch-resistant, but it still won't survive a drop to the sidewalk. However, that could all change if University of Akron scientists get their shatterproof touchscreen film into shipping hardware. They've developed transparent electrodes that, when layered on polymer surfaces, are just as transparent as current technology (indium tin oxide) but much more durable. You can bend them over 1,000 times without breaking, and they also hold up against peeling.

More importantly, the technology is cheap. In fact, the university believes that it should be less expensive to make this film than the touchscreen tech in use today; you can simply mass-produce it in rolls. While there's no firm production timetable, scientists fully expect their technology to hit stores in the future. Eventually, you won't have to worry quite so much that your phone might slip out of your hands.

drag2share: Your smart TV can be hacked over the air, but it's not likely

source: http://www.engadget.com/2014/06/08/over-the-air-smart-tv-hack/?utm_source=Feed_Classic_Full&utm_medium=feed&utm_campaign=Engadget&?ncid=rss_full

Samsung's 85-inch 4K curved TV

It only makes sense that putting a TV online theoretically exposes it to hackers, but it's now clear that those hacks don't have to go through conventional internet pipelines. A team of Columbia University researchers has published details of a vulnerability in an interactive TV standard (HbbTV) that lets evildoers hijack your smart TV and other devices in your home network so long as you tune into a specific over-the-air digital channel. Attacks can run undetected in the background, and the nature of the broadcasts makes it difficult or impossible to trace the culprit. Reportedly, the only surefire remedies are to cut off broadcast-based web content altogether, monitor for unusual spikes in network activity or notify users when apps launch.

However, you shouldn't fret about someone stealing your data just because you tuned into the Home Shopping Network. If you only watch shows over cable or satellite, this issue won't affect you; as it stands, HbbTV hasn't yet reached North America. It's also difficult for would-be hackers to reach many people without signal amplifiers. Still, the security hole isn't going to be very comforting to cord cutters who still want the benefits of an internet-connected TV set.
