Robot surgeon uses frighteningly large needle to remove shrapnel, your resistance
We've reported on many a creepy looking and dangerous sounding robot in the past, but this one might just take the cake when it comes to dominating your nightmares for the next few nights. Developed by a team at Duke University, the bot uses ultrasound to identify areas of density in human flesh, then starts probing them with a rather painfully large looking needle. It could be used to locate and extract bits of shrapnel from stricken GIs on the battlefield, but that same tech might also be deployed to pierce women's breasts and men's prostates -- ostensibly to treat cancers of those respective regions, but we can think of more nefarious reasons. The bot doesn't have a name, but once it and its kind take over, neither will you. [Via gizmag]
PhonePoint Pen application is a hand-talkers' dream come true
Know someone who talks with their hands so expressively that you have to step back or risk catching a wayward exclamation point in the face? The video after the break will make their day. Students at Duke University have come up with a way to use phone accelerometers to capture gestures with surprising precision, allowing them to pipe those motions through a character recognition algorithm and, hey presto, turn flapping hands into letters and numbers. The prototype app is called PhonePoint Pen, and while right now the process looks painfully slow, with large, precise motions required, with a few months or years of refinements you might just be able to jot down a quick text to a friend while running between terminals, all without putting down the double latte that just cost you $8 at the airport food court. The future, dear readers, it's closer than you think.[Via Yahoo! News]
Laid-off 3D Realms staff reveal Duke Nukem Forever concept art
Having just lost their positions at 3D Realms, artists Chris Smith, Trammell Issac and Layne Johnson have created new blogs to show off their previous work in search of a new industry gig. Included on all three blogs are concept art, renders and pretty much more than we've ever seen of Duke Nukem Forever. Just prior to press time, Chris Smith's blog was taken offline, but the images were saved and can be viewed in the gallery below.If 3D Realms closing its doors proved anything, it was that Duke Nukem Forever's 13-year development odyssey really was happening all along. Unfortunately, since the house that built Duke has closed up shop, the '90s hero's latest adventure will tentatively be referred to as Duke Nukem For-Never... until someone else gets crazy enough to take over development.%Gallery-63065%%Gallery-32891%[Thanks, Darius B.]
Robot doctors join the fight against breast cancer
From Da Vinci robosurgeons to helpful nursebots , robots are becoming commonplace in hospitals the world over -- and now researchers at Duke University have developed a rudimentary tabletop robot that uses 3D ultrasound technology to detect a 'lesion' in a simulated sponge breast, pinpoint its exact location, and perform a biopsy. All the calculations are performed by the device itself, using what has been described as "a basic artificial intelligence program." The next step in the research will be an upgrade that will that the robotic arm from three-axis to six-axis capability, and a change from the old sponge-based simulated breast to one made from turkey breasts, which approximates the density of human breast tissue. According to Stephen Smith, director of the Duke University Ultrasound Transducer Group, if things stay on track, robots will be performing routine breast exams and biopsies in five to ten years.

Researchers create wirelessly-powered robot swarm
Wireless power has come a long way from Nikola Tesla's early ruminations on the matter, and it looks like some researchers from Duke and Georgia Tech are now taking the idea to its logical, robot-powering conclusion. While their setup (thankfully) isn't yet able to power robots beyond the confines of the Q L-C resonator-equipped table, it does appear to work remarkably well in that limited proof-of-concept, with five bots each equipped with a non-resonant pickup coil able to follow a path around the table, or simply sit still to recharge their batteries. They were even able to power an LED light with the system for good measure. Natually, they eventually hope to expand the system to power larger swarms of robots and do away with the need for batteries altogether. Yeah, that's a good idea. Head on past the break for a video.
Player-created hairstyles look pretty snazzy
The Blizzard-created hairstyles revealed from a while back didn't really impress too much -- while almost everyone will certainly be trying the barbershop in the expansion, no one I know is running there just to put a certain haircut on. But Kxara has set out with some texture design and a model maker to change all that -- she's come up with some of her own hairstyles, and they look really great.Some of them are just jokes from real-life hairstyles (the Duke is really funny, and I like the dastardly Blood Elf mustache, too), but some of them really pull off the characters in a way we haven't seen before. There no afro, unfortunately (or fortunately, depending on how you look at it), and Kxara says that's because of the low polygon count on the characters -- either they'd have to go with high polygons and wreck low-end machines, or go low polygons, and it would look bad for everyone.With barbershops in the game, Blizzard's starting haircuts are probably not the last we'll see (and maybe someday we'll even have faction or question haircuts), but these specs put together by Kxara are a good place to start if they decide to add more.[via Resto4Life]
Duke micro-bots learning to dance, probe cellular architectures
We won't even front: Duke's quasi-invisibility cloak is far cooler than this, but a team of microscopic robots sure have the potential to do more good than a glorified figment of someone's imagination. Bruce Donald, a Duke professor of computer science and biochemistry, has teamed up with a few other mad scientists in order to create ridiculously tiny robots that can dance on objects smaller than a pin's head. According to Mr. Donald, they are "almost 100 times smaller than any previous robotic designs of their kind and weigh even less." Sure, watching these critters do the tango is undoubtedly entertaining, but he's hoping to collaborate with the medical center in order to "probe the molecular and cellular architectures of very small things such as cells." We appreciate the dedication to mankind and all, but don't pretend like you don't goof off with these guys on your coffee breaks, Bruce.[Via Slashdot]
Duke inches toward autonomous robo-surgeons
We're a little ambivalent about robots performing surgery autonomously and unattended, but there are clearly cases where it'd be beneficial, and it seems like an inevitable future. Duke researchers working on robo-doc lab feasibility studies announced this week a proof of concept using 3D ultrasound mapping to enable machines to "see" what they're doing. The first test procedures have focused on use of those ultrasound transducers in catheter-based procedures using fluoroscopy, so it sounds like we'll still have a few years before we say ahhh for a machine.
SKY's Duke is only slightly more attractive than The Duke
"Luxurious yet simple design" is the name of the game for SKY's latest bit of mobile splendor, curiously named "Duke" of all things. For many of us, "Duke" conjures up images of rough-and-tumble sheriffs in the Wild West or gargantuan Xbox controllers, but one thing it doesn't necessarily bring to mind is "luxurious yet simple." No bother, we suppose it's the hardware that matters, so let's get to it: 2.4 inch QVGA display, 1.3 megapixel camera, document viewer, media player, Bluetooth, and built-in subway maps (Korean subways, that is) all grace the rather plainly styled slider. Look for it on your favorite Seoul retailer's shelf for something in the range of 400,000 won (about $404).[Via Unwired View]
Duke University: home to world's largest 802.11n wireless network
We know, most of you Blue Devil fans are still reeling from that recent loss to Wake Forest, but if it's any consolation, at least your campus is about to become home to the "world's largest" 802.11n wireless network. Last we heard, The Ohio State University held the crown for Earth's biggest WLAN with 1,700 access points lit, but according to Cisco, Duke's campus will soon house 2,500 Aironet 1250 Series APs. The installation will leave more than six million square feet of central North Carolina blanketed in WiFi, and will supposedly be the "largest planned 802.11n wireless network in the world by any organization to date." Watch out, Dukies -- we hear those folks in Chapel Hill have a thing for swiping unsecured signals.
Researchers say three-dimensional sound cloak is possible, in theory
Apparently not content with simply building an invisibility cloak, of sorts, those mad scientists at Duke University's Pratt School of Engineering now say that they've found that a three-dimensional "sound cloak" is also possible, in theory. According to Duke's Steven Cummer, the researchers have come up with a "recipe" for an acoustic material that would "essentially open up a hole in space and make something inside that hole disappear from sound waves." Needless to say, they haven't tested that possibility just yet, but they say it could one day be used to hide submarines from detection by sonar or even be used to improve the acoustics of a concert hall by making inconvenient structural beams effectively disappear. What's more, they say that the basic principles at play here could also suggest that cloaks could be created for other wave systems, like seismic waves, or even waves at the surface of the ocean, although the practical applications for those would seem to be a bit more limited.[Image courtesy of Royal Navy/BAE Systems]
Monkeys take their robot-wielding powers international
It's been a while since we've heard from the folks at Duke University and their robot-controlling monkeys, but it seems that they've remained hard at work on their potentially perilous collaboration, with them recently showing off some of their latest tricks at the Neuroscience 2007 conference earlier this month. This time, they had the monkeys control a pair of robot legs through the use of some electrodes implanted in their brains which, apparently, went off without a hitch. But that's not all! The legs the monkeys were controlling just so happened to be located at the Advanced Telecommunications Research Institute International in Kyoto, Japan, which the monkeys were linked to via the Internet. No word on what they plan to attempt next, although taking the robots and/or monkeys into space would seem to be the next logical step (at least to us).[Photo courtesy of NASA-JSC / Wikimedia Commons]
Virtual reality game gets Pavlovian on crack addicts
Bless you classical conditioning, for without you we wouldn't have stories about virtual crack dens. A Duke University developed game is attempting virtual reality therapy for crack addicts hoping to break their addiction. Prof Zack Rosenthal states that the game takes people "into a virtual crack-related neighborhood or crack-related setting and have them experience cravings, just like they would in the real world." Rosenthal says cravings are a mental and learned behavior which the game attempts to quell.Subjects will face in-game temptations and be required to rate their level of craving, after which the craving is expected to subside due to the game's inability to deliver a real fix. The therapist then ties the moment the craving subsides to a tone trigger, leading the addict to "associate the sound with the sensation of a decreased craving." Yup, it's all one giant virtual reality "Pavlov's Dog" simulator. [Via GamePolitics]
Ben Heck crams wireless Xbox 360 controller into original Xbox controller
Yeah, we doubt that summary rolled off the average tongue, but regardless, modder extraordinaire Ben Heck has managed to stuff the guts of an Xbox 360 wireless controller into the frame of an original Xbox controller. Often dubbed "The Duke," the massive device actually proved rather hard to work with, though one may assume that you could actually cram the entire Xbox 360 into this beast with all that room. Nevertheless, the final product actually looks fairly unscathed, save for the tiny, recessed Sync button on the rear, the added Guide button on the front and the headset port at the base, but it sounds like this may be the only one to ever be created by the hands of Mr. Heck. You know what that means -- get your bid in or live with unimaginable regret.[Via Coolest-Gadgets]
Wireless problem was Cisco bug, not iPhone traffic, says Duke
As Dave noted on Friday, we expected to hear more from Duke on the iPhone-killed-our-network story, and we did -- on Friday the university released a statement that identified the problem, now resolved, as "a Cisco-based network issue" which has now been patched. The iPhone has been fully exonerated as a cause or victim of the wireless issue, demonstrating once again that correlation does not necessarily imply causation. Hey, it's not like Cisco's still bitter about the whole iPhone trademark thing, either.It seems that Kevin Miller, with Duke's IT department, jumped the gun a bit last week when he told Network World, with considerable confidence, that the iPhone was at the root of Duke's wireless problems. "I don't believe it's a Cisco problem in any way, shape or form," he said. Oops. Sounds familiar to me... network guys always bristle when someone says "it's a router problem," and the immediate (and often correct) reaction is to blame the newest devices on the LAN. Don't worry, Mr. Miller, we've got the perfect Sysadmin Appreciation Day gift for you: a fruit basket, chock full of Apples.via Macworld
Duke exonerates iPhone from network outage charges
Granted, the original report suggesting that swarms of iPhones actually broke Duke's WiFi network did seem a bit bizarre, and now it appears that the university is freeing Apple's handset from blame. Interestingly, the actual culprit still seems somewhat veiled in secrecy, as we're only informed that "a particular set of conditions made the Duke wireless network experience some minor and temporary disruptions in service," but never do they exaggerate on exactly what caused the hiccups. Still, Duke also stated that it worked in conjunction with Cisco and Apple in order to "identify the network issue that was causing the problem," and since Cisco stepped in and provided a fix, the prpblem has yet to repeat itself. Looks like you're off the hook on this one, iPhone.
iPhones bedevil Duke
Well apparently things aren't so rosy with iPhones at Duke University. Their IT managers are reporting that iPhones are actually causing many of their wireless access points to shut down for 10-15 minutes each. Because of some sort of misconfiguration involving the Address Resolution Protocol the iPhones "flood the access points with up to 18,000 address requests per second, nearly 10Mbps of bandwidth, and [monopolize] the AP's airtime."The article notes that all of this is being caused by only ~150 iPhones, and the IT folks are worried about what's going to happen when the school year starts and hundreds, if not thousands more, show up on the campus network. Apparently the Duke folks are convinced the problem is not with their Cisco equipment and have been in contact with Apple, but they have not gotten much of a response. If this is in fact a problem with the iPhone's design we should expect to see more of this kind of thing on large wifi networks. Have any of you noticed any kind of problems like this on campus or at work?[via MacVolPlace]
iPhones bogging down Duke University's WiFi network?
While the Blue Devils may have their basketball program running like a well-oiled machine, apparently its wireless LAN structure is in dire need of an upgrade. Reportedly, so many Dukies have snatched up iPhones and began using the campus WiFi network to surf on the go that the hordes of requests have been "temporarily knocking out anywhere from a dozen to 30 wireless access points at a time." Cisco, the university's main WLAN provider, has been called in to find out exactly why the overload has brought the network to its proverbial knees, and we'd say they better resolve the problem pronto -- after all, this issue could be magnified immensely with the commencement of the fall semester.[Via Fox News]
Duke researchers envision mind-controlled weaponry
The Blue Devils certainly haven't fared well on the hardwood of late, but a group of engineering minds at Duke University are thinking up ways to get even. While we can't actually confirm the motives, a recent patent filing spells out details of a device that can "use the brain's thoughts to control an array of mechanical and electrical devices, up to and including weapons." Thought-controlled interfaces have long since been available, but these researchers are suggesting that everything from household items like televisions and ovens to "weapons systems" could be used to not only "improve one's quality of life," but could actually produce thoughts that litearlly kill. Interestingly, the verbiage even mentions that the recently-ratified UWB technology could be used to beam commands from your devious brain, and although it's not surprising to find that DARPA has a hand in funding department, we're still not any closer to finding out when our military will switch from triggers to impulses.

Learn to walk with Walking Navi
Now that your brain is sufficiently trained, you can begin figuring out how to move around! Okay, so really it presumes you already know how to walk and are interested in walking as exercise. Too bad, because it's a lot funnier the other way. Just like Cooking Navi and Dokodemo Yoga, Duke Saraie no Kenkou Walking Navi (Duke Saraie's Health Walking Navi) is designed so that users can choose their program, set their DS systems down and have directions barked at them while they follow along. Fitness celebrity Duke Saraie will help you warm up, then lead you through your workout. Wait, workout? We want to try this to see what kinds of "workouts" could be involved other than "walk for a while", "walk for longer than the last time", and "walk for a while, but faster".Try Screenshot Inspecting Navi after the post break.[Via NeoGAF]
