Fruit fly flight simulator could smarten up robots
Wondering just how we mere mortals were going to even give a robot enough smarts to completely overtake our societies? Oddly enough, some of that artificial brain power could come from studying the way fruit flies, um, fly. A completely bizarre flight simulator at Caltech actually plays "scenes" that flys react to, and considering that the fly is constantly held, researchers can closely examine how the insect attempts to navigate away from lines, blobs and all manners of incoming obstacles. Those working with the installation suggest that these studies could one day help autonomous robots function better, potentially taking some of the load off of our human workforce. We know, you've got three bold letters and a question mark running through your noggin right now -- just hit the read link to see what it's all about.[Thanks, Dave]
Researchers churn out "world's densest" memory circuit
Undoubtedly, there's been quite a few chips claiming to hold some sort of "world's smallest" title, but a team of researchers have crafted what they call the "most dense computer memory circuit ever fabricated," capable of "storing around 2,000 words in a unit the size of a white blood cell." Scientists at Caltech and UCLA put their proximity differences behind them for a bit to develop a 160-kilobit memory cell that purportedly has a record-setting density of "100 gigabits per square centimeter." The bantam chip is capable of holding a document the size of the US Declaration of Independence with room leftover for a few quarterly reports (or slow jams), but Caltech chemistry professor James Heath doubts that we'll see it in mainstream action anytime soon. Still, the team isn't backing down from its discovery, and hopes to see this manufactured and placed into laptops in the coming years.[Via Slashdot]
da Vinci robot creators being sued by Caltech
It's no secret that doctors ought to have a good bit of insurance on their side due to the flurry of medical malpractice (and similar) lawsuits that hit hospitals and surgeons everyday, but you know things are rough when robotic MDs get taken to court as well. Intuitive Surgical Inc., the creators of the da Vinci system for robotic surgery, has been sued by the California Institute of Technology, which claims that the system "infringes four patents held by the university." Obviously, Intuitive's CEO called the suit "outrageous and without merit," but the Pasadena school is nevertheless "seeking an injunction" and repayment for "damages." What's notable about the case, however, is where it was filed, as Tyler, Texas is quite a long ways from both institutions, but attorney's in the know have called the Lonestar State "a haven for patent pirates." Of course, there are rulings out there that are finally leaning the way of the tech firms at hand, suggesting that "obvious patent laws" should be relaxed somewhat, but it seems that even this probably won't mess with Texas. Nevertheless, let's just hope one of those lawyers doesn't end up under a (disgruntled) da Vinci knife one day.[Via RobotGossip]
Caltech scientists build DNA logic circuits that run in a test tube
We've seen DNA logic before (remember the MAYA-II, the DNA computer that could play tic-tac-toe?), but a new variety at Caltech has created a set of circuits that can work in salt water, possibly paving the way for cell-based computers. The researchers created a small series of circuits and included gates to perform all the binary logic functions: AND, OR, and NOT. Each gate, a set of DNA strands, receives DNA molecules as input and spits out different ones as output. They've succeeded in building 12 gates in a cascade five layers deep -- pretty simple compared to your average microchip, but nonetheless pretty impressive. Ok Caltech, we'll let your computer partner up with MAYA-II and we'll take 'em both on in a game of competitive Sudoku, how's that?
