Scientists copy keys with computer imaging to make sure we feel insecure


Not satisfied with the time-honored traditions of lockpicking or bump keying, computer science professor Stefan Savage and a handful of grad students at the University of California at San Diego have developed a computer system that makes a functional copy of a key based solely on a photograph, regardless of angle or distance -- the image resolution just has to be high enough to make out the details. They claim they did this "to show people that their keys are not inherently secret" so they'll be more careful about flaunting them around in their Flickr photos, but we're worldly enough to know that they really did it to steal beer from rival frat houses. Shame!

Flying plasmonic lens system could lead to denser chips / disks


Last we heard, IBM was busy extending optical lithography down to 30-nanometers in order to keep Moore's Law intact, and some two years later, the process is still being honed by engineers at the University of California, Berkeley. Reportedly, gurus there with IQs far greater than ours have developed a new patterning technique (plasmonic nanolithography) that could make "current microprocessors more than 10 times smaller, but far more powerful." Additionally, professor Xiang Zhang asserts that this same technology could eventually "lead to ultra-high density disks that could hold 10 to 100 times more data than disks today." The secret to the madness is a flying plasmonic head, which is compared to the arm and stylus of an LP turntable; the setup enables researchers to "create line patterns only 80-nanometers wide at speeds up to 12-meters per second, with the potential for higher resolution detail in the near future." In layman's terms? That CPU you purchased last month will, in fact, be old hat in due time.

California white hat hackers: 3, Diebold and friends: 0


In a move which will bolster your undoubtedly high sensations of "faith" in the US voting process, a group of University of California researchers have just hacked their way through security on nearly every voting machine certified by the state of California. According to Secretary of State Debra Bowen, who initiated these tests, the team was able to "bypass physical and software security in every machine they tested." The group, which was sanctioned by the state, was given full access to the machines, as well as their source code and manuals, leaving some to argue that the test doesn't accurately depict how vulnerable the machines are -- because we all know how hard it is for hackers to get their hands on that kind of stuff. The report will affect whether or not Bowen approves the systems for use throughout California in its upcoming presidential primaries. It looks like 2008 is going to be an exciting year, to say the least.

Autonomous robotic fleas could create distributed sensor network

We've seen a fair bit of mesh networking approaches lately, and thanks to a unusual project going on at the University of California, Berkeley, the next great ad hoc network could be started by a horde of bugs. Sarah Bergbreiter has developed an "autonomous robotic flea has been developed that is capable of jumping nearly 30 times its height," thanks to what could possibly be hailed as the "world's smallest rubber band." Interestingly, the creator hopes that the minuscule bugs could eventually be used to "create networks of distributed sensors for detecting chemicals or for military-surveillance purposes." The Smart Dust initiative could eventually be expanded to grow wings, but for now the solar-powered bugger will stick to hoppin' via a "microcontroller to govern its behavior and a series of micro electromechanical systems (MEMS) motors on a silicon substrate."
