Submission + - Electric 'thinking cap' controls learning speed (scienceblog.com)

Submitted by Anonymous Coward
An anonymous reader writes: Vanderbilt researchers say they've shown it's possible to selectively manipulate our ability to learn by applying a mild electrical current to the brain. Using an elastic headband that secured two electrodes conducted by saline-soaked sponges to the cheek and the crown of the head, the researchers applied 20 minutes of transcranial direct current stimulation (tDCS) to each subject. Depending on the direction of the current, subjects either learned more quickly, slower, or in the case of a sham current, with no change at all. The study appears in the current issue of the Journal of Neuroscience.

Comment Film him (Score 1) 188

I'm really surprised that people don't whip out their camera phones and film him. He's obviously trying to hide his identity.

Especially after watching his videos, If some idiot got in my face in a public place and didn't go away, I'd just pull out my own phone & film him, telling him I plan to expose his identity "Oh.. you must be the 'surveillance camera guy'.. This is going to be an awesome YouTube post. A lot of people have been wondering what you look like so that they can kick your ass.."

Gartner Says 3D Printers Will Cost Less Than $2,000 By 2016 170

Posted by samzenpus from the get-you-one dept.
colinneagle writes "Widespread adoption of 3D printing technology may not be that far away, according to a Gartner report predicting that enterprise-class 3D printers will be available for less than $2,000 by 2016. 3D printers are already in use among many businesses, from manufacturing to pharmaceuticals to consumers goods, and have generated a diverse set of use cases. As a result, the capabilities of the technology have evolved to meet customer needs, and will continue to develop to target those in additional markets, Gartner says."

United States Begins Flying Stealth Bombers Over South Korea 567

Posted by samzenpus from the nice-day-for-a-flight dept.
skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

4-Billion-Pixel Panorama View From Curiosity Rover 101

Posted by samzenpus from the take-a-look dept.
A reader points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."

DOJ Often Used Cell Tower Impersonating Devices Without Explicit Warrants 146

Posted by Unknown Lamer from the bending-the-rules dept.
Via the EFF comes news that, during a case involving the use of a Stingray device, the DOJ revealed that it was standard practice to use the devices without explicitly requesting permission in warrants. "When Rigmaiden filed a motion to suppress the Stingray evidence as a warrantless search in violation of the Fourth Amendment, the government responded that this order was a search warrant that authorized the government to use the Stingray. Together with the ACLU of Northern California and the ACLU, we filed an amicus brief in support of Rigmaiden, noting that this 'order' wasn't a search warrant because it was directed towards Verizon, made no mention of an IMSI catcher or Stingray and didn't authorize the government — rather than Verizon — to do anything. Plus to the extent it captured loads of information from other people not suspected of criminal activity it was a 'general warrant,' the precise evil the Fourth Amendment was designed to prevent. ... The emails make clear that U.S. Attorneys in the Northern California were using Stingrays but not informing magistrates of what exactly they were doing. And once the judges got wind of what was actually going on, they were none too pleased:"

Google Pledges Not To Sue Any Open Source Projects Using Their Patents 153

Posted by Unknown Lamer from the now-and-forever dept.
sfcrazy writes "Google has announced the Open Patent Non-Assertion (OPN) Pledge. In the pledge Google says that they will not sue any user, distributor, or developer of Open Source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google's patents covered by the pledge to other technologies." This is in addition to the Open Invention Network, and their general work toward reforming the patent system. The patents covered in the OPN will be free to use in Free/Open Source software for the life of the patent, even if Google should transfer ownership to another party. Read the text of the pledge. It appears that interaction with non-copyleft licenses (MIT/BSD/Apache) is a bit weird: if you create a non-free fork it appears you are no longer covered under the pledge.

What Does It Actually Cost To Publish a Scientific Paper? 166

Posted by Unknown Lamer from the one-trillion-dollars dept.
ananyo writes "Nature has published an investigation into the real costs of publishing research after delving into the secretive, murky world of science publishing. Few publishers (open access or otherwise-including Nature Publishing Group) would reveal their profit margins, but they've pieced together a picture of how much it really costs to publish a paper by talking to analysts and insiders. Quoting from the piece: '"The costs of research publishing can be much lower than people think," agrees Peter Binfield, co-founder of one of the newest open-access journals, PeerJ, and formerly a publisher at PLoS. But publishers of subscription journals insist that such views are misguided — born of a failure to appreciate the value they add to the papers they publish, and to the research community as a whole. They say that their commercial operations are in fact quite efficient, so that if a switch to open-access publishing led scientists to drive down fees by choosing cheaper journals, it would undermine important values such as editorial quality.' There's also a comment piece by three open access advocates setting out what they think needs to happen next to push forward the movement as well as a piece arguing that 'Objections to the Creative Commons attribution license are straw men raised by parties who want open access to be as closed as possible.'"

The Man Who Sold Shares of Himself 215

Posted by Unknown Lamer from the social-experiments-gone-awry dept.
RougeFemme writes "This is a fascinating story about a man who sold shares in himself, primarily to fund his start-up ideas. He ran into the same issues that companies run into when taking on corporate funding — except that in his case, the decisions made by his shareholders bled over into his personal life. This incuded his relationship with his now ex-girlfriend, who became a shareholder activist over the issue of whether or not he should have a vasectomy. The experiment continues."

USPS Discriminates Against 'Atheist' Merchandise 1121

Posted by Soulskill from the heathens-don't-need-shoes dept.
fish waffle writes "Suspecting that their strongly branded 'Atheist' products may be treated differently by more religiously-oriented postal regions, Kickstarter success Atheist Shoes conducted an experiment. They sent 178 packages to 89 people in different parts of the U.S., each person receiving one package prominently branded as 'Atheist' merchandise, and one not. The results: packages with the atheist label were nearly 10 times more likely to be 'lost,' and took on average 3 days longer to show up when they did. Control experiments were also done in Europe and Germany — it's definitely a USPS problem."

Submission + - What are the Unwritten Rules of Deleting Code? (arstechnica.com) 3

Submitted by Press2ToContinue
Press2ToContinue writes: I came across this page that asks the question, "what are the unwritten rules of deleting code?"

It made me realize that I have seen no references to generally-accepted best-practice documents regarding code modification, deletion, or rewrites. I would imagine /.'s have come across them if they exist. The answers may be somewhat language-dependent, but what best practices do /.'s use when they modify production code?

Submission + - JavaScript is the New Perl

Submitted by theodp
theodp writes: 'People are thoroughly excited [about JavaScript],' writes Lincoln Baxter. 'However, I’d akin this to people discovering Perl during the advent of C and C++ (mirror). Does it work? Yes. Is it pretty? Not by a long shot.' Baxter adds, 'While I do like both languages, JavaScript [is] just waiting for the next technology to come around and make it look like Perl does today: pervasive, but lacking enterprise adoption on large applications.' So, is JavaScript is doomed to become the next Perl?
