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."

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.

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."

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.

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."
Censorship

Censoring a Number 1046

Rudd-O writes "Months after successful discovery of the HD-DVD processing key, an unprecedented campaign of censorship, in the form of DMCA takedown notices by the MPAA, has hit the Net. For example Spooky Action at a Distance was killed. More disturbingly, my story got Dugg twice, with the second wave hitting 15,500 votes, and today I found out it had simply disappeared from Digg. How long until the long arm of the MPAA gets to my own site (run in Ecuador) and the rest of them holding the processing key? How long will we let rampant censorship go on, in the name of economic interest?" How long before the magic 16-hex-pairs number shows up in a comment here?

New Horizons Probe's Images of Jupiter 86

SeaDour writes "The Pluto-bound New Horizons space probe, launched a little over a year ago, recently succeeded in passing through a narrow navigational keyhole by Jupiter. Using the gas giant's tremendous gravity, the craft now has a significant boost toward its final destination, shaving three years off the time it would otherwise spend en-route. As it passed through the Jovian system, the probe took some fantastic images of the neighborhood, including detailed observations of erupting volcanoes on Io, time-lapse photography of Jupiter's tumultuous atmosphere, and the faint ring system that was first discovered in Voyager photography. These new images prove the capabilities of the small probe, which is set to reach Pluto in 2015."

Bill Gates Brags About Vista, Reacts to Apple's Latest Ads 891

fr8_liner writes "In an unusually candid interview with Newsweek Bill Gates lays it all on the line, bragging about the benefits of Vista, ragging on Apple for their 'I'm a Mac' ads, and claiming primacy in a number of features shared by Vista and OSX. Specifically, it is Mr. Gates' opinion that the Apple adverts are misleading if not untruthful. He makes the claim that 'security guys break the Mac every single day. Every single day, they come out with a total exploit, your machine can be taken over totally. I dare anybody to do that once a month on the Windows machine.' The interview also touches on the future of Microsoft and Operating systems, and some of the company's plans for internet-based computing."

Inhabited Island Vanishes Forever Underwater 408

PhreakOfTime writes "For the first time the rising ocean levels have washed away an inhabited island. Lohachara island was at one point home to some 10,000 people. It, along with several other spits of land near the Indian mainland, is now permanently underwater. From the article: ' As the seas continue to swell, they will swallow whole island nations, from the Maldives to the Marshall Islands, inundate vast areas of countries from Bangladesh to Egypt, and submerge parts of scores of coastal cities. Eight years ago ... the first uninhabited islands - in the Pacific atoll nation of Kiribati - vanished beneath the waves. The people of low-lying islands in Vanuatu, also in the Pacific, have been evacuated as a precaution, but the land still juts above the sea. The disappearance of Lohachara, once home to 10,000 people, is unprecedented.'"
