A New Look At Brain Control
one_neuron_two_neuron writes "Researchers at Harvard have taken a new look at how electricity can make neurons fire in the brain. The scientists found some surprising things: if you stick an electrode in the brain and apply current, you don't just make a small group of neurons fire — many neurons fire a long way away from the electrode. That's probably because instead of activating the cell bodies of the neurons, their axons fire. Those axons are the wiring of the brain. Your cerebral cortex is something like a big pile of unwound yo-yos — if you stick an electrode into the cortex, you're much more likely to hit the strings (the axons), and the yo-yo connected to the string can be really far away. So, how will you ever hook up a computer to your brain? This data shows that we need to rethink how to do that with electrical current. If you stick an electrode in one place, neurons in a totally different place will fire. New optogenetic methods (e.g. using viral delivery of proteins) might work. Or possibly we will figure out how to make the brain learn to interpret these sparse, widespread electrical patterns. New optical techniques have made a dramatic impact on neuroscience recently, and this study uses pulsed-laser-scanning microscopy (two-photon microscopy) to take pictures of neurons deep inside the living brain. The academic paper (PDF) is available on the author's site."Read more of this story at Slashdot.
Solar Roadways Get DoT Funding
mikee805 writes "Solar Roadways, a project to replace over 25,000 square miles of road in the US with solar panels you can drive on, just received $100,000 in funding from the Department of Transportation for the first 12ft-by-12ft prototype panel. Each panel consists of three layers: a base layer with data and power cables running through it, an electronics layer with an array of LEDs, solar collectors and capacitors, and finally the glass road surface. With data and power cables, the solar roadway has the potential to replace some of our aging infrastructure. With only 15% efficiency, 25,000 square miles of solar roadways could produce three times what the US uses annually in energy. The building costs are estimated to be competitive with traditional roads, and the solar roads would heat themselves in the winter to keep snow from accumulating."Read more of this story at Slashdot.
Making an Open Source Project Press-Friendly
blackbearnh writes "Corporations know that part of launching a successful project is projecting the right image to the media. But a lot of open source projects seem to treat the press as an annoyance, if they think about it at all. For a reporter, even finding someone on a project who's willing to talk about it can be a challenge. Esther Schindler over at IT World has a summary of a roundtable discussion that was held at OSCON with pointers about how open source projects can be more reporter-accessible. 'Recognize that we are on deadline, which for most news journalists means posting the article within a couple of hours and for feature authors within a couple of days. If we ask for input, or a quote, or anything to which your project spokesperson (you do have one? yes? please say yes) might want to respond, it generally does mean, "Drop everything and answer us now." If the journalist doesn't give you a deadline ("I need to know by 2pm"), it's okay to ask how long you can take to reach the right developer in Poland, but err on the side of "emergency response." It's unreasonable, I know, but so are our deadlines.'"Read more of this story at Slashdot.
Court of Appeals Rejects FCC's Cable Subscriber Cap
olsmeister writes "The US Court of Appeals Friday threw out the FCC's cap on the number of cable subscribers one operator can serve, saying the FCC was 'derelict' in not giving DBS its due as a legitimate competitor. 'We agree with Comcast that the 30% subscriber limit is arbitrary and capricious. We therefore grant the petition and vacate the Rule,' said the court, which concluded that there was ample evidence of an increasingly competitive communications marketplace and that cable did not have undue control on the programming pipeline. The FCC commissioner's statement (PDF) is available online."Read more of this story at Slashdot.
Crime Expert Backs Call For "License To Compute"
The Cable Guy writes to mention that Russel Smith, one of Australia's principal criminologists, is pushing for first-time computer users to be required to earn a license to browse the web. "The Australian Computer Society launched computer driver's licenses in 1999. It aimed to give users a basic level of competency before they started using PCs. But the growth in cybercrime has led to IT security experts such as Eugene Kaspersky to call for more formalized recognition of a user's identity so they can travel the net safely. Last week Dr. Smith sat in front of a Federal Government Inquiry into cybercrime and advised Australia's senior politicians on initiatives in train to fight cybercrime. He said that education was secondary to better technology solutions."Read more of this story at Slashdot.
NVIDIA Predicts 570x GPU Performance Boost
Gianna Borgnine writes "NVIDIA is predicting that GPU performance is going to increase a whopping 570-fold in the next six years. According to TG Daily, NVIDIA CEO Jen-Hsun Huang made the prediction at this year's Hot Chips symposium. Huang claimed that while the performance of GPU silicon is heading for a monumental increase in the next six years — making it 570 times faster than the products available today — CPU technology will find itself lagging behind, increasing to a mere 3 times current performance levels. 'Huang also discussed a number of "real-world" GPU applications, including energy exploration, interactive ray tracing and CGI simulations.'"Read more of this story at Slashdot.
Oracle To Sell Sun's Hardware Business To HP?
Underholdning writes "With the DOJ approving Oracle's Sun buyout the question arises what Oracle might want to do with Sun's hardware business. It's no secret that what Oracle wanted was the software part. Now The Inquirer is running a story claiming that Oracle will sell the hardware business of Sun to HP. This will give Oracle a juicy check while HP can increase its services. Larry Ellison denies that it will take place, but a source for CNN claims otherwise."Read more of this story at Slashdot.
Publisher Whining Prompts Italian Investigation of Google
Complaints about "lack of transparency" from publishers have prompted Italian competition authorities to begin an investigation of Google's search and news services. I'm sure their motives are completely altruistic. "Because Google does not disclose the criteria for ranking news articles or search results, he said, newspapers are unable to hone their content to try to earn more revenue from online advertising. Ad revenue on the Web is directly proportional to the size of the audience, which is heavily influenced by search or Google News rankings."Read more of this story at Slashdot.
Swedish Regulators Ban Word "Bank" In Domain Names For Non-Banks
It seems that Swedish regulators have decided to extend the requirement of not calling yourself a bank to the registration of domain names. Now anyone that tries to register a .SE domain name with the word "bank" in it will need to prove they are a legitimate bank. Hopefully there are no blood banks or anyone with the last name of "Banks" that might want a .SE domain. Here is a Google translation of the demand issued by the authorities to the .SE registry.Read more of this story at Slashdot.
Emergency Government Control of the Internet?
TheZid writes "A newly proposed bill would give Uncle Sam the power to disconnect private sector computers from the internet in the event of a 'cyber security emergency.' As usual, our government is trying to take away our privacy by citing security. What actually counts as a 'Cyber-Security Emergency?' Does the president now have the option of disconnecting people when they disagree with his policies? How about disconnecting bloggers that criticize his health care reform? What counts as an emergency? Can political opponents be deemed a cyber-security emergency?"Read more of this story at Slashdot.
Apple Faces Inquiries In the EU On iPhone Accidents
o'reor writes "As more cases of iPhone screen explosions emerge in the news on this side of the pond, Apple is now facing official inquiries and lawsuits in France. This situation has forced Apple finally to break silence and acknowledge the incidents: 'We are aware of these reports and we are waiting to receive the iPhones from the customers. Until we have the full details, we don't have anything further to add.' Following those reports, the European Commission had already decided last week to step in, while Apple tried to dismiss the problem as 'isolated incidents.' Meanwhile, iPhone explosion-related sites are now popping up on the Internet, releasing games such as iPop to chill out and relax on the subject, but also giving users advice on preventing iPhone accidents, or detecting imminent explosions."Read more of this story at Slashdot.
Homeland Security Changes Laptop Search Policy
IronicToo writes "The US Government has updated its policy on the search and seizure of laptops at border crossing. 'The long-criticized practice of searching travelers' electronic devices will continue, but a supervisor now would need to approve holding a device for more than five days. Any copies of information taken from travelers' machines would be destroyed within days if there were no legal reason to hold the information.'"Read more of this story at Slashdot.
Treasured "Moon Rock" Is Petrified Wood
Hugh Pickens writes "BBC reports that a treasured piece at the Dutch national museum — a supposed moon rock from the first manned lunar landing given to former Prime Minister Willem Drees during a goodwill tour by the three Apollo-11 astronauts shortly after their moon mission in 1969 — has been revealed as nothing more than petrified wood, curators say. A jagged fist-size stone with reddish tints, it was mounted and placed above a plaque that said, 'With the compliments of the Ambassador of the United States of America... to commemorate the visit to The Netherlands of the Apollo-11 astronauts.' The plaque does not specify that the rock came from the moon's surface. Researchers from Amsterdam's Free University said they could see at a glance the rock was probably not from the moon. They followed the initial appraisal up with extensive testing. 'It's a nondescript, pretty-much-worthless stone,' wrote Geologist Frank Beunk in an article published by the museum. Beunk says the rock, which the museum at one point insured for more than half a million dollars, was worth no more than $70. The 'rock' had originally been been vetted through a phone call to NASA. As the US Embassy in the Hague said it was investigating the matter, the Rijksmuseum says it will keep the piece as a curiosity."Read more of this story at Slashdot.
We're In the Midst of a Literacy Revolution
Mike Sauter sends in a piece from Wired profiling research by Andrea Lunsford, a professor of writing and rhetoric at Stanford, from which she concludes that we don't need to worry about computers and the Internet causing a decline in general literacy. "[Lunsford] has organized a mammoth project called the Stanford Study of Writing to scrutinize college students' prose. From 2001 to 2006, she collected 14,672 student writing samples — everything from in-class assignments, formal essays, and journal entries to emails, blog posts, and chat sessions. Her conclusions are stirring. 'I think we're in the midst of a literacy revolution the likes of which we haven't seen since Greek civilization,' she says. For Lunsford, technology isn't killing our ability to write. It's reviving it — and pushing our literacy in bold new directions."Read more of this story at Slashdot.
IBM Images a Single Molecule
chrb writes "New Scientist is reporting that researchers at IBM Zurich have managed to image a single molecule in detail for the first time. In the images of a pentacene molecule, the bonds between the carbon atoms are visible as five linked rings."Read more of this story at Slashdot.
