One of the most insidious types of malware is a "rootkit," which can effectively hide the presence of other spyware or viruses from the user - allowing third parties to steal information from your computer without your knowledge. But now researchers from North Carolina State University have devised a new way to block rootkits and prevent them from taking over your computer systems. http://www.physorg.com/news176452213.html Technology - Computer Sciences Tue, 03 Nov 2009 06:30:44 EST news176452213 (PhysOrg.com) -- MIT researchers and designers are developing the Affective Intelligent Driving Agent (AIDA) - a new in-car personal robot that aims to change the way we interact with our car.

He finds himself wandering across a dark surface etched with green gridlines and strewn with geometric shapes, above which hover strange equations. One of these is the deceptively simple assertion that P = NP. http://www.physorg.com/news176037013.html Technology - Computer Sciences Thu, 29 Oct 2009 12:10:40 EST news176037013 (PhysOrg.com) -- Computer scientists have developed a method to synthesize the sounds of cymbals, falling garbage cans and lids, and plastic water-cooler bottles and recycling bins. http://www.physorg.com/news175889668.html Technology - Computer Sciences Tue, 27 Oct 2009 19:15:37 EST news175889668 Electrical engineers recently pitted Genius - the music recommendation system in Apple's iTunes - against two experimental music recommender systems. Genius appears to capture acoustic similarities among songs within the same playlist, the researchers found. The University of California, San Diego electrical engineers also discovered that the music recommender they built from scratch can generate song playlists that human subjects thought were as good as those that Genius generates. The UC San Diego system works for songs that Genius knows nothing about. http://www.physorg.com/news175884578.html Technology - Computer Sciences Tue, 27 Oct 2009 17:50:03 EST news175884578 (PhysOrg.com) -- Following news reports that 65,000 modems and wireless routers used by Time Warner Cable customers are vulnerable to attack by hackers, a Columbia University expert on computer security and privacy has found that software flaws in embedded devices like routers, webcams and Voice over Internet Protocol (VoIP) phone adapters are far more widespread than previously known. http://www.physorg.com/news175788913.html Technology - Computer Sciences Mon, 26 Oct 2009 15:50:01 EST news175788913 (PhysOrg.com) -- In 1995, a good computer chip had a clock speed of about 100 megahertz. Seven years later, in 2002, a good computer chip had a clock speed of about three gigahertz -- a 30-fold increase. And now, seven years later, a good computer chip has a clock speed of... still about three gigahertz. http://www.physorg.com/news175509292.html Technology - Computer Sciences Fri, 23 Oct 2009 09:35:53 EST news175509292 (PhysOrg.com) -- While you can't yet teleport or clone yourself to be in two places nearly at once, computer scientists are working on what might be the next best thing. http://www.physorg.com/news175198398.html Technology - Computer Sciences Mon, 19 Oct 2009 19:15:24 EST news175198398 Scientists at the California Institute of Technology (Caltech) have created a remote-controlled robot that is able to simulate the "visual" experience of a blind person who has been implanted with a visual prosthesis, such as an artificial retina. An artificial retina consists of a silicon chip studded with a varying number of electrodes that directly stimulate retinal nerve cells. It is hoped that this approach may one day give blind persons the freedom of independent mobility. http://www.physorg.com/news175183657.html Technology - Computer Sciences Mon, 19 Oct 2009 15:08:24 EST news175183657 (PhysOrg.com) -- If computers could recognize objects, they could automatically search through hours of video footage for a particular two-minute scene. A tourist strolling down a street in a strange city could take a cell-phone photo of an unmarked monument and immediately find out what it was. And an Internet image search on, say, "Shakespeare" would pull up pictures of Shakespeare, not pictures of Gwyneth Paltrow in the movie Shakespeare in Love. Though object recognition is one of the major research topics in computer vision, MIT researchers may have found a way to make it much more practical. http://www.physorg.com/news174646349.html Technology - Computer Sciences Tue, 13 Oct 2009 10:30:07 EST news174646349 (PhysOrg.com) -- A University of Dundee graduate has created a computer system with the potential to make the game of Blackjack fairer by detecting card counters and dealer errors. http://www.physorg.com/news174491549.html Technology - Computer Sciences Sun, 11 Oct 2009 15:02:28 EST news174491549 (PhysOrg.com) -- To expand the boundaries of machine intelligence, Ben Taskar is using television shows with large fan bases like CSI, Alias, and Lost to teach computers how to be smarter about what they see, hear and read. http://www.physorg.com/news173980519.html Technology - Computer Sciences Mon, 05 Oct 2009 17:40:05 EST news173980519 (PhysOrg.com) -- High-powered internet applications typically need teams of experts to maintain them.

Focusing somewhere between the two can ensure that neither is blurry; but neither will be particularly sharp, either. On Friday, at the IEEE Conference on Computer Vision in Kyoto, Japan, members of the MIT Graphics Group will show that combining several low-quality exposures with different focal depths can yield a sharper photo than a single, higher-quality exposure. http://www.physorg.com/news173541725.html Technology - Computer Sciences Wed, 30 Sep 2009 15:04:22 EST news173541725 A way to filter out denial of service attacks on computer networks, including cloud computing systems, could significantly improve security on government, commercial, and educational systems.
