BrainPort Lets the Blind "See" With Their Tongues
Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year.Read more of this story at Slashdot.
Developing World's Parasites, Diseases Enter US
reporter alerts to a story up at the Wall Street Journal on the increasing prevalance in the US of formerly rare, 3rd-world diseases such as toxocariasis, chagas, and cysticercosis. Health-care legislation pending in the House calls for a full report to Congress about the threat from this cluster of diseases, termed "neglected infections of poverty." "Parasitic infections and other diseases usually associated with the developing world are cropping up with alarming frequency among US poor, especially in states along the US-Mexico border, the rural South, and in Appalachia, according to researchers. Government and private researchers are just beginning to assess the toll of the infections, which are a significant cause of heart disease, seizures and congenital birth defects among black and Hispanic populations. ... 'These are diseases that we know are ten-fold more important than swine flu,' said [one] leading researcher in this field. 'They're on no one's radar.' ... These diseases share a common thread. 'People who live in the suburbs are at very low risk,' Dr. Hotez said. But for the 37 million people in the US who live below the poverty line, he said, 'There is real suffering.'"Read more of this story at Slashdot.
How To Prove Someone Is Female?
krou writes "Caster Semenya won the 800m at the World Athletics Championship in blistering style leaving her competitors in the dust, but she has been thrown into the midst of a scandal amidst claims that she's not really a woman. According to the many press reports, she's believed to shave, is flat chested, has a very masculine physique, previously preferred playing physical games with boys, and shunned traditional female activities and clothing. Questions about her gender have dogged her entire career. Previously, acceptance that she is a women relied on simple inspection of female genitals. But now the IAAF claim that they want to conduct further tests to see if 'she may have a rare medical condition that gives her an unfair advantage.' An IAAF spokesmen noted that 'The [testing] process was started after Semenya made her startling breakthroughs — a 25-second improvement at 1500m and eight seconds at 800m, just some weeks ago.' I'm curious what the Slashdot community thinks: what can be considered proof of someone being male or female? Is it simply a case of having the right genitals, or are there other criteria that should be used? Is the IAAF right in claiming that someone should be prevented from competing because they have a rare medical or genetic advantage?"Read more of this story at Slashdot.
IBM, Other Multinationals "Detaching" From the US
theodp writes "If you're brilliant, work really hard, and earn a world-class doctorate from a US university, IBM has a job for you at one of its US research sites — as a 'complementary worker' (as this 1996 piece defined the then-emerging term). But be prepared to ship out to India or China after you've soaked up knowledge for 13 months as a 'long-term supplemental worker.' Newsweek sketches some of the bigger picture, reporting that IBM, HP, Accenture, and others are finding it profitable to detach from the United States (even patenting the process). 'IBM is one of the multinationals that propelled America to the apex of its power, and it is now emblematic of the process of creative destruction pushing America to a new, less dominant, and less comfortable position.'"Read more of this story at Slashdot.
RIAA Loses Case Against Launch Media
NewYorkCountryLawyer writes "The RIAA's claim that personalized internet radio stations were 'interactive services' was flatly rejected 'as a matter of law' by the US Court of Appeals for the Second Circuit, in Arista Records v. Launch Media. In affirming the jury's verdict in favor of the defendant, Launch Media — acquired during the lawsuit by Yahoo! — the Court said it did not even need to concern itself with possible errors in the jury instructions, since the trial judge should have directed a verdict for defendant 'as a matter of law' on the question of whether the radio stations were 'interactive services.' At pages 23-42 of its 42-page opinion (PDF), the appeals court carefully analyzed how Launch Media's personalized internet radio stations worked, and noted that the users could neither obtain and play on demand a particular song, nor obtain the transmission of a particular program, thus rendering the RIAA's claim of 'interactivity' meritless."Read more of this story at Slashdot.
Big Bang Could Be Recreated Inside a Metamaterial
KentuckyFC writes "Metamaterials are substances with a permittivity and permeability that has been manipulated in a way that allows fine control over the behavior of light. They have famously been used to create an invisibility cloak that hides objects from view. Now Igor Smolyaninov, a physicist in the US, has calculated how metamaterials could be used for a much more profound demonstration: to reproduce the behavior of light in various kinds of spacetimes, in particular a (2+2) spacetime (one having two dimensions of space and two of time). His method is to show that there is formal mathematical analogy between the way metamaterials and spacetimes affect light. He goes on to show how a phase transition in a (2+2) spacetime leads to the creation of a (2+1) spacetime filled with photons, an event analogous to the Big Bang." Here are the abstract and the preprint (PDF).Read more of this story at Slashdot.
Twitter Developing Location-Based API
adeelarshad82 writes "Twitter developers are now working on a location-based API that will provide accurate information on your whereabouts. Developers will be able to add latitude and longitude to any tweet. The option will definitely be opt-in. Folks will need to activate this new feature by choice, and the exact location data won't be stored for an extended period of time."Read more of this story at Slashdot.
Obstacles Near Emergency Exits Speed Evacuation
BuzzSkyline writes "Despite fire codes that require emergency exits be clear of obstacles, some types of obstacles actually speed evacuation. The counterintuitive conclusion resulted from a series of experiments performed at a TV studio in Japan. Researchers from the University of Tokyo asked 50 volunteers to exit the studio through a narrow door. Video tapes of the experiments show that people made it out quickest when a pole was placed about 30 degrees to one side of the exit. The lead researcher believes an obstacle reduces jamming and friction among people in crowds by decreasing conflicts as the crowd presses toward the exit. A paper describing the research is scheduled to appear in the journal Physical Review E in September, but a preprint is available on the Physics Arxiv."Read more of this story at Slashdot.
Switzerland's Data Protection Watchdog Wants Street View Disabled
glow-in-the-dark writes "The Swiss office for Data Protection has asked Google to turn off Street View within the country because it doesn't meet the conditions demanded when permission was given to go ahead with the photography. Google answered privacy concerns with the following points (I'm translating them from German; here's an automated translation): 'Google will publish in advance where it is going to record the images, so you can act accordingly.' Do they want you to hide? Where is the real obligation here? 'Google has made masking the images of people and car license plates obligatory.' I think this is where trouble starts, because their permission to go ahead appears to have been dependent on how well they did this. I have browsed one particular town as an experiment and was quite quickly able to find unmasked faces. This means that either the algorithm they use doesn't work, or that it is done manually and they've fallen behind (in which case they should not have put up the images). 'Although a picture of a home is generally not covered under Data Protection, Google has agreed to remove them if asked. Follow the same process as removing a person.' I think it wouldn't be half as bad if the pictures weren't taken with a high enough resolution to see inside a house. In short, Google has not been given the easy ride it had in other countries regarding Street View. I actually suspect there is more to come."Read more of this story at Slashdot.
EVE Bans Exploiters; Dropping 2% of Users Cuts Average CPU Usage 30%
Earthquake Retrofit writes "Ars has a story about EVE Online banning thousands of accounts for real-world trading of in-game money for profit. From the article: 'Those who buy and sell ISK, the game's currency, are not only exploiting the game, but unbalancing play. That's why the company decided to go drastic: a program they called "Unholy Rage." For weeks they studied the behavior and effects these real-money traders had on the game, and then they struck. During scheduled maintenance, over 6,000 accounts were banned. [Einar Hreiðarsson, EVE's lead GM,] assures us that the methods were sound, and the bannings went off with surgical precision. ... While the number of accounts banned in the opening phase of the operation constituted around 2 percent of the total active registered accounts, the CPU per user usage was cut by a good 30 percent.' Looks like they got the right 6,000.' Further information and more graphs are available from the EVE dev blog."Read more of this story at Slashdot.
Google Brings SVG Support To IE
stelt writes "Scalable Vector Graphics (SVG) is in most graphical tools. It is used heavily in many big projects, such as KDE and Wikipedia. But Internet Explorer's lack of built-in support for SVG was keeping it away from mainstream use on the web. Google is fixing that now with a JavaScript drop-in named SVGWeb. They've posted a quick, one-minute overview, a longer and more detailed presentation, and you can read about it on the project page."Read more of this story at Slashdot.
Sweden Launches Criminal Probe of Pirate Bay Sale
uolamer writes with word that the Economic Crimes Bureau in Sweden has opened an investigation into the upcoming purchase of The Pirate Bay by Global Gaming Factory X. Quoting: "The Swedish newspaper SvD reported Saturday that authorities are looking for possible insider trading after Global Gaming's stock jumped a week before they announced plans to acquire The Pirate Bay. Trading of Global Gaming shares was halted by AktieTorget, a Swedish exchange, on Friday after officials there requested proof that Global Gaming had enough money to complete the sale. Global Gaming has yet to produce the required documentation. Until officials get the proof they need, they said they won't allow the stock to be traded again"Read more of this story at Slashdot.
Federal Court Grants Microsoft Expedited Appeal
patentpundit writes "On Friday, August 21, 2009, the United States Court of Appeals for the Federal Circuit granted Microsoft an expedited appeal of its patent infringement loss to i4i Limited Partnership. On August 11, 2009, Microsoft lost a $300 million judgment for infringing the XML patents of i4i by selling Word. Microsoft was given 60 days to stop selling Word, or implement work arounds that did not utilize the infringed technology. Microsoft filed an emergency appeal with the Federal Circuit, and requested a stay of the permanent injunction that will force them to stop selling work 60 days from August 11, 2009. The Federal Circuit granted an expedited oral argument, which will take place on September 23, 2009. Microsoft requested an administrative stay of the permanent injunction, which was denied, and then filed a petition to stay the injunction pending appeal. i4i has until August 25, 2009, to respond to Microsoft's request to stay the injunction pending appeal."Read more of this story at Slashdot.
A Broken Heart Really Does Hurt, Scientists Claim
Death Metal writes "Psychologists at the University of California, Los Angeles say the human body has a gene that connects physical pain sensitivity with social pain sensitivity. The findings back the common theory that rejection 'hurts' by showing that a gene regulating the body's most potent painkillers — mu-opioids — is involved in socially painful experiences too."Read more of this story at Slashdot.
