Brain Changes When Viewing Violent Media 448

Ponca City, We Love You writes "Scientists at Columbia University have used Magnetic Resonance Imaging (fMRI) to show that a brain network responsible for suppressing inappropriate or unwarranted aggressive behaviors became less active after study subjects watched several short clips from popular movies depicting acts of violence. These changes could render people less able to control their own aggressive behavior. Although research has shown some correlation between exposure to media violence and real-life violent behavior, there has been little direct neuroscientific support for this theory until now. 'Depictions of violent acts have become very common in the popular media,' said researcher Christopher Kelly. 'Our findings demonstrate for the first time that watching media depictions of violence does influence processing in parts of the brain that control behaviors like aggression.' The full research paper is published on the The Public Library of Science, a peer-reviewed, open-access, online publication, that publishes all its articles under a Creative Commons Attribution License."

Submission + - Microfluidic Chips made with Shrinky Dinks

SoyChemist writes: "When she started her job as a new professor at UC Merced, Michelle Khine was stuck without a clean room or semiconductor fabrication equipment, so she went MacGyver and started making Lab-on-a-Chip devices in her kitchen with Shrinky Dinks, a laser printer, and a toaster oven. She would print a negative image of the channels onto the polystyrene sheets and then make them smaller with heat. The miniaturized pattern served as a perfect mould for forming rounded, narrow channels in PDMS — a clear, synthetic rubber."

SixApart Sells LiveJournal to Russian Media Company 172

molrak writes "SixApart tonight announced the sale of journal/blogging service Livejournal to Russia-based SUP. Original LJ founder Brad Fitzpatrick has chimed in on the situation: 'This is pretty cool because - They're ridiculously excited about LiveJournal, and have been for awhile (they previous purchased advertising rights in Russia, but ended up doing a bunch of Russia-specific LJ development as well). They want to throw a lot of resources at LiveJournal in terms of product development and engineers. "LiveJournal.com, Inc." now stands alone again, focusing on nothing but LJ. Sounds like I'll have more LJ influence (via new role as advisory board member) than I've had recently.'"

Cannabis Compound Said To "Halt Cancer" 383

h.ross.perot informs us of research out of the California Pacific Medical Center Research Institute suggesting that a compound found in cannabis may stop breast cancer from metastasizing. Cannabidiol, or CBD, could develop into a non-toxic alternative to chemotherapy some years down the road, if animal and human trials bear out its effectiveness. The article notes that smoking cannabis will not deliver significant quantities of CBD.

US Control of Internet Remains an Issue 303

Hugh Pickens writes "A UN-sponsored Internet conference ended with little progress on the issue of US control over the domain name system run by ICANN, a California-based nonprofit over which the US. government retains veto power. By controlling the core systems, the United States indirectly influences the way much of the world uses the Internet. As the conference drew to a close, the Russian representative, Konstantin Novoderejhkin, called on the United Nations secretary-general to create a working group to develop ''practical steps'' for moving Internet governance ''under the control of the international community.'' The United States insists that the existing arrangements ensure the Internet's stability and there's little indication that the US government and ICANN plan to cede their roles over domain names anytime soon. ''I think (there are) a small number of countries that are very agitated and almost don't care what the facts are,'' said Internet pioneer Vint Cerf, who stepped down as ICANN's chairman earlier this month. ''It's a very small vocal group bothered by this issue. ICANN has existed for eight years and done a great job with its plans for internationalization.'' With no concrete recommendations for action, the only certainty going forward is that any resentment about the American influence will only grow as more users from the developing world come online, changing the face of the global network. The next forum will held next year in New Delhi, India."

Fighting Back Against Ghost Calls 297

An anonymous reader writes "You're doing something interesting. The phone rings. You get up, pick up the phone, and hear only silence. It could be a slasher waiting outside your house, but it's probably an errant computer at a telemarketer. This article describes how some are fighting back by setting up websites to track the worst telemarketers by their caller ids. The article mentions whocalled.us (one of the funnier urls I've ever seen), 800notes.com and numberzoom.com . One intrepid guy is even writing a program to check these sites when the call comes in before ringing the phone."

Submission + - Firefox Memory Hogging Is Due to Fragmentation (pavlov.net)

A beautiful mind writes: It has been long claimed by users that Firefox leaks memory, and on the other hand the developers claimed the number of leaks are minimal. It turns out both groups were right. Stuart Parmenter, one of the authors of the RAMBack extension started investigating and found out that the issue is memory fragmentation. He discovered that while loading about:blank uses 12,589,696 bytes of memory in the test he performed (image), after exercising Firefox with different websites and then clearing the caches with the help of the RAMBack extension the picture is wholly different: "Our heap is now 29,999,872 bytes! 16,118,072 of that is used (up 4,634,208 bytes from before... which caches am I forgetting to clear?). The rest, a whopping 13,881,800 bytes, is in free blocks!"

Bot-avatar Pesters Second Life Users (For Science!) 124

holy_calamity writes "A bot-controlled avatar that tracks down lone avatars in Second Life and purposely invades their personal space has been created by UK researchers. The idea was to see if users value their virtual personal space. Bots avatars are not encouraged by Linden Labs — although this one is being deployed by academics, presumably spam-avatars (spavatars?) won't be far behind."

Games All Downhill Since Pong? 403

In a recent article Nolan Bushnell laments the current state of gaming, stating that modern games are nothing more than a "race to the bottom" resulting in complete and utter trash. In order to combat what he sees as the downward spiral in game quality he continues to work on his new dining experience uWink that features tabletop games and a "reasonably priced meal". RPS weighs in on the subject arguing that, while the unhealthy obsession with Halo 3 might be a bit misplaced, there are plenty of gems to be found amidst the flotsam and jetsam.

Unofficial Patch For Windows URI Hole 85

dg2fer writes "For more than two months, the vulnerability of parsing URIs has been known for a number of Windows programs, including Outlook, Adobe Reader, IRC clients, and many more. Microsoft admitted the vulnerability only last week. The latest Microsoft patches published on October's Patch Tuesday did not include a solution, so hackers have taken on the problem themselves. One, KJK::Hyperion, has published (as open source) an unofficial patch that cleans up the critical parameters of URI system calls before calling the vulnerable Windows system function."

IBM, Linden Labs Call For Portable Avatars 93

destinyland writes "IBM just announced a push for universal avatars with Second Life's creator Linden Labs. Then they joined Google, Cisco, Intel, Sony, Microsoft, and Motorola for the first planning session on how to make it happen. There's already speculation that Google is working on a 3-D social networking environment incorporating Google Earth and Google Maps." Virtual Worlds News has up a copy of the joint press release.

Meteorite Causes Illness in Peru 357

eldavojohn writes "A meteorite struck in Peru on Saturday leaving cinders, rock & water boiling out of the ground. Villagers nearby reported headaches & vomiting and attributed it to the event. From the article, 'Seven policemen who went to check on the reports also became ill and had to be given oxygen before being hospitalized, Lopez said. Rescue teams and experts were dispatched to the scene, where the meteorite left a 100-foot-wide (30-meter-wide) and 20-foot-deep (six-meter-deep) crater, said local official Marco Limache.' It's not yet clear whether this is from the meteorite, gas trapped underground that was released or a chemical reaction between the two."

Solar Craft Flies Through Two Nights 156

An anonymous reader writes "A solar-powered, unmanned craft has flown for 54 hours — a record for both unmanned aerial vehicles and solar craft. None before has managed to store enough solar energy to fly through more than one night. There is also a video showing the 18m carbon fiber wing craft being launched."

OOXML Vote and the CPI Corruption Index 190

Tapani Tarvainen writes "It turns out there's an interesting correlation between Transparency International's 'corruption perceptions index' and voting behavior in ISO's OOXML decision. Countries with a lower score (more corruption) on the 2006 CPI were more likely to vote in favor of OOXML, and those with a higher score were less likely. According to the analysis, 'This statistics supports with a P value of 0.07328 the hypothesis that the corrupted countries were more likely to vote for approval (one-tailed Fisher's Exact test). In other words, simplified a bit: the likelihood that there was no positive correlation between the corruption level and probability of an approval vote, that is, this is just a random effect, is about 7%.' Of course, correlation doesn't prove causality."
