Bay Area To Install Electric Vehicle Grid 388

Posted by kdawson from the recharge-it dept.
Mike writes "Recently San Francisco, San Jose, and Oakland unveiled a massive concerted effort to become the electric vehicle capitol of the United States. The Bay Area will be partnering with Better Place to create an essential electric vehicle infrastructure, marking a huge step towards the acceptance of electric vehicles as a viable alternative to those that run on fossil fuels." Inhabitat.com has some conceptual illustrations and a map showing EV infrastructure, such as battery exchange stations, stretching from Sacramento to San Diego — though this is far more extensive than the Bay Area program actually announced, which alone is estimated to cost $1 billion.

Google Sorts 1 Petabyte In 6 Hours 166

Posted by Soulskill from the sort-of-fast dept.
krewemaynard writes "Google has announced that they were able to sort one petabyte of data in 6 hours and 2 minutes across 4,000 computers. According to the Google Blog, '... to put this amount in perspective, it is 12 times the amount of archived web data in the US Library of Congress as of May 2008. In comparison, consider that the aggregate size of data processed by all instances of MapReduce at Google was on average 20PB per day in January 2008.' The technology making this possible is MapReduce 'a programming model and an associated implementation for processing and generating large data sets.' We discussed it a few months ago. Google has also posted a video from their Technology RoundTable discussing MapReduce."

Brain Changes When Viewing Violent Media 448

Posted by Zonk from the argh-must-destroy-pokemans dept.
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."
