Translating Brain Waves Into Words |
|
cortex writes with an excerpt from the L.A. Times: "In a first step toward helping severely paralyzed people communicate more easily, Utah researchers have shown that it is possible to translate recorded brain waves into words, using a grid of electrodes placed directly on the brain. ... The device could benefit people who have been paralyzed by stroke, Lou Gehrig's disease or trauma and are 'locked in' — aware but unable to communicate except, perhaps, by blinking an eyelid or arduously moving a cursor to pick out letters or words from a list. ... Some researchers have been attempting to 'read' speech centers in the brain using electrodes placed on the scalp. But such electrodes 'are so far away from the electrical activity that it gets blurred out,' [University of Utah bioengineer Bradley] Greger said. ... He and his colleagues instead use arrays of tiny microelectrodes that are placed in contact with the brain, but not implanted. In the current study, they used two arrays, each with 16 microelectrodes."

Journalist Tricked Captors Into Twitter Access |
|
itwbennett writes "Kosuke Tsuneoka, a Japanese freelance journalist held captive in Afghanistan since April 1, was released over the weekend. His freedom came a day after he sent two Twitter messages from a captor's phone. 'i am still allive [sic], but in jail,' read a message sent at 1:15 p.m. GMT on Friday. It was followed a few minutes later with a second message, also in English, that read, 'here is archi in kunduz. in the jail of commander lativ.' The message referred to the Dasht-e-Archi district of Kunduz where he was being held. On Tuesday, speaking in Tokyo, Tsuneoka revealed how he managed to convince his captors to give him access to the Internet. 'He asked me if I knew how to use it, so I had a look and explained it to him,' said Tsuneoka. 'I called the customer care number and activated the phone,' he said."

Stanford's Authoritative Alternative To Wikipedia |
|
eldavojohn writes "For decades, Stanford has been working on a different kind of Wikipedia. It might even be considered closer to a peer-reviewed journal, since you have get submissions past a 120 person group of leading philosophers around the world, not to mention Stanford's administration. It has several layers of approval, but the authoritative model produces high quality content — even if it only amounts to 1,200 articles. Content you can read straight through to find everything pertinent — not hop around following link after link like the regular Wikipedia. You might question the need for this, but one of the originators says, 'Our model is authoritative. [Wikipedia's] model is one an academic isn't going to be attracted to. If you are a young academic, who might spend six months preparing a great article on Thomas Aquinas, you're not going to publish in a place where anyone can come along and change this.' The site has articles covering topics from Quantum Computing to technical luminaries like Kurt Friedrich Gödel and Alan Turing. The principal editor said, 'It's the natural thing to do. I'm surprised no one is doing it for the other disciplines.'"

Researchers Say Happiness Costs $75k |
|
SpuriousLogic writes "Does happiness rise with income? In one of the more scientific attempts to answer that question, researchers from Princeton have put a price on happiness. It's about $75,000 in income a year. They found that not having enough money definitely causes emotional pain and unhappiness. But, after reaching an income of about $75,000 per year, money can't buy happiness. More money can, however, help people view their lives as successful or better. The study found that people's evaluations of their lives improved steadily with annual income. But the quality of their everyday experiences — their feelings — did not improve above an income of $75,000 a year. As income decreased from $75,000, people reported decreasing happiness and increasing sadness, as well as stress. The study found that being divorced, being sick and other painful experiences have worse effects on a poor person than on a wealthier one."
