owlgorithm writes "A USC research group has created software, named ARMOR (Assistant for Randomized Monitoring over Routes), that will be used at LAX Airport to make security and police operations there truly unpredictable. The software records the locations of routine, random vehicle checkpoints and canine searches at the airport, and police provide data on possible terrorist targets, based in part on recent security breaches or suspicious activity. The software then makes random decisions (which are thankfully based on calculated probabilities of terrorist attacks) and tells the police where to dispatch and when. The most notable detail is that terrorists who had access to ARMOR still wouldn't be able to predict the searches."

An anonymous reader writes "It appears that the initial rumor of the SWORDS robots being pulled out of Iraq — and its subsequent correction — were just that: sensationalizing in the blogosphere. Popular Mechanics has a lengthy update to its original scoop, digging into the sketchy responses from defense contractors when pressed about the bot's actual duties in battle. From the article: 'Although others have used our story to generate a false online rumor about these armed UGVs, the nature of those "technical issues" that Gotvald mentioned in his statement, and that Qinetiq and Foster-Miller have yet to address directly, remains a mystery. Until someone can explain why SWORDS lost its funding, and what exactly it is — and isn't — being used for in Iraq, the rumors are likely to continue. If this is the dawn of the era of robotic infantry, things are off to a decidedly rocky start.""

Nanotech Coward writes "The unknown human health and environmental impacts of nanotechnology are a bigger worry for scientists than for the public, according to a new report in the journal Nature Nanotechnology. The new report was based on a national telephone survey of American households and a sampling of 363 leading U.S. nanotechnology scientists and engineers. It reveals that those with the most insight into a technology with enormous potential — and that is already emerging in hundreds of products — are unsure what health and environmental problems might be posed by the technology."

Several readers let us know about a little problem with presidential hopeful John McCain's MySpace page. Looks as though some staffer didn't read the fine print of the "credit" clause when selecting a template for the page. The template author and CEO of Newsvine, Mike Davidson, noticed this and didn't care too much. But the McCain page was pulling an image from Davidson's site, costing him bandwidth every time someone visited the candidate's MySpace page. So Davidson changed the image in question to read: "Today I announce that I have reversed my position and come out in full support of gay marriage... particularly marriage between two passionate females." Here is Davidson's account of the "immaculate hack".

Masq666 writes "A Norwegian team has made the first piece of hardware that uses evolution to change its design at runtime to solve the problem at hand in the most effective way. By turning on and off its 'genes' it can change the way it works, and it can go through 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years." The University of Oslo press release linked from the article came out a few days ago; the researchers published a paper (PDF) that seems to be on this same technology at a conference last summer.
