Rescue robots map and explore dangerous buildings, prove there's no 'I' in 'team' (video)
We've seen robots do some pretty heroic things in our time, but engineers from Georgia Tech, the University of Pennsylvania and Cal Tech have now developed an entire fleet of autonomous rescue vehicles, capable of simultaneously mapping and exploring potentially dangerous buildings -- without allowing their egos to get in the way. Each wheeled bot measures just one square foot in size, carries a video camera capable of identifying doorways, and uses an on-board laser scanner to analyze walls. Once gathered, these data are processed using a technique known as simultaneous localization and mapping (SLAM), which allows each bot to create maps of both familiar and unknown environments, while constantly recording and reporting its current location (independently of GPS). And, perhaps best of all, these rescue Roombas are pretty team-oriented. Georgia Tech professor Henrik Christensen explains: "There is no lead robot, yet each unit is capable of recruiting other units to make sure the entire area is explored. When the first robot comes to an intersection, it says to a second robot, 'I'm going to go to the left if you go to the right.'" This egalitarian robot army is the spawn of a research initiative known as the Micro Autonomous Systems and Technology (MAST) Collaborative Technology Alliance Program, sponsored by the US Army Research Laboratory. The ultimate goal is to shrink the bots down even further and to expand their capabilities. Engineers have already begun integrating infrared sensors into their design and are even developing small radar modules capable of seeing through walls.

Ultra-thin handheld microscope could sniff out skin cancer, forged documents
It may not look like it, but that sleek black thing pictured above is actually a microscope. Designed by engineers at Germany's Fraunhofer Institute for Applied Optics and Precision Engineering IOF, this little guy boasts a 5.3mm optical length, rendering it slim enough to fit in the palm of your hand, yet powerful enough to deliver images at a scanner-like resolution of five micrometers, over a wide surface area. Fraunhofer's researchers achieved this balance by essentially tossing out the manual on traditional microscope design. Whereas most devices slowly scan areas and construct images on a piecemeal basis, this handheld uses several small imaging channels and a collection of tiny lenses to record equal sized fragments of a given surface. Unlike conventional scanner microscopes, all of these 300 x 300 square micrometer imaging channels are captured at the same time. With a single swipe, then, users can record 36 x 24 square mm shots of matchbox-sized objects, without even worrying about blurring the images with their shaky hands. The prototype is still two years away from going into production, but once it does, engineers say it could help doctors scan patients for skin cancer more easily, while also allowing bureaucrats to quickly confirm the authenticity of official documents. We can only imagine what it could do for Pac-Man. Full PR after the break.
Amar Bose donates majority of Bose Corporation shares to MIT, says thanks for the education
If you haven't heard of Dr. Amar Bose directly, you've surely heard of his eponymous audio equipment company. Late last week, the 81-year old founder and chairman of Bose Corporation announced that he's donating the majority of shares in the privately held company to his alma mater, the Massachusetts Institute of Technology. A member of that college's graduating class of 1951 and its electrical engineering faculty all the way until 2001, Bose felt compelled to give something back and he's opted for the most grandiose of gestures. MIT won't be able to sell its shares in Bose Corp. nor have any say in the way it is run, but it'll receive dividends as and when they're paid out, which will then be reinvested in its research and education programs. In making this perpetual endowment public, Amar Bose took the time to credit Professors Y. W. Lee, Norbert Wiener and Jerome Wiesner as his mentors -- in the image above, you can see him pictured with Lee (left) and Wiener (right) back in 1955. Chalkboards, that's where it all began.
Researchers build synthetic synapse circuit, prosthetic brains still decades away
Building a franken-brain has long been a holy grail of sorts for scientists, but now a team of engineering researchers have made what they claim to be a significant breakthrough towards that goal. Alice Parker and Chongwu Zhou of USC used carbon nanotubes to create synthetic synapse circuits that mimic neurons, the basic building blocks of the brain. This could be invaluable to AI research, though the team still hasn't tackled the problem of scope -- our brains are home to 100 billion neurons, each of which has 10,000 synapses. Moreover, these nanotubes are critically lacking in plasticity -- they can't form new connections, produce new neurons, or adapt with age. All told, the scientists say, we're decades away from having fake brains -- or even sections of it -- but if the technology advances as they hope it will, people might one day be able to recover from devastating brain injuries and drive cars smart enough to avert deadly accidents.
Addon Spotlight: Work harder with GnomeWorks
Each week, WoW Insider brings you a fresh look at reader-submitted UIs as well as Addon Spotlight, which focuses on the backbone of the WoW gameplay experience: the user interface. Everything from bags to bars, buttons to DPS meters and beyond -- your addons folder will never be the same. This week, GnomeWorks is to trade skills what fire was to cavemen. These past few weeks have been very good in the old email box for suggestions for addons to be featured on Addon Spotlight, so keep those recommendations coming. In the next few weeks, I've got a recommendation spotlight planned as well as a grab bag. Also, there is an idea kicking around in my head about a "my first addon" spotlight, where new addon developers pitch their addon and we talk about it constructively. What do you guys think? Today's Addon Spotlight is one of those "long time coming" pieces; people were utterly shocked over the fact that I had not talked about GnomeWorks before. Well, there is a good reason for that -- GnomeWorks is still in its alpha development stage. As far as profession windows go, prior to Cataclysm, an addon of this type was almost required. The sorting features and customization options on the default profession window was lackluster at best.
Test subjects with electrode implants use mind control to move a cursor
As trippy as mind-control still seems to us, we've already seen it implemented in everything from wheelchairs to pricey gaming (and car driving!) headsets. But the problem is that they measure brain activity outside the skull -- you know, the thing we've evolved to shield the murky goings-on in our minds from prying EEG sensors. Now, though, a team of Washington University researchers appears to have happened upon a more effective -- albeit, invasive -- approach. The researchers got some brave specimens to move a mouse cursor by implanting plastic pads containing electrodes underneath their skulls, with the sensors sitting on the surface of the brain. That, they say, gives them access to more telling, high-frequency waves that say a lot more about cognitive intentions. In the end, the subjects moved the cursors by thinking one of these sounds: "ee," "ah," "oo," and "eh." Brain-computer interfaces ain't new, of course, but the scientists say the subjects with electrode implants had more success than people wearing electrode-studded EEG caps, which could translate to less frustration for people with severe disabilities.
AMO Arm pneumatic prosthetic does mind-control on the cheap
We're no strangers to amputees moving stuff with their minds -- for that matter, a thought-controlled prosthetic isn't really new to us, either -- but the pneumatic arm you see here isn't like other intelligent limbs. Unlike most mind-operated prosthesis, the Artificial Muscle-Operated (AMO) Arm doesn't require invasive surgery, and according to its inventors, it costs a quarter of the price to make. Here's how the thing works: the host human wears a headset that sends brain signals to a chip in the arm that then matches those signals to a database of related actions, triggering a series of pneumatic pumps and valves to move the limb. Thus, if the wearer thinks 'up,' the arm moves up. The AMO Arm's creators, a pair of undergraduate biomed students, say that not only is their invention a steal to produce, but it also takes just minutes to acclimate to, which has us wondering, do you have to be missing an arm to get a hold of one of these things? You know, we can always use an extra hand. Full PR after the break.
iMobot creeps, crawls, cranes its way into our hearts (video)
It may not look like much, but this little modular robot's got the stuff to give Keepon a run for its money -- oh yeah, and according to its creators, iMobot's got big implications for the field of robotics too. Sporting four degrees of freedom, two rotating joints, and a pair of faceplates that act as wheels, the patent-pending device can crawl, drive, and potentially act as an autonomous camera platform. The surprisingly agile hunk of machinery was developed by two UC Davis professors who say their versatile invention could aid in search and rescue, as well as education and research. We think it's super cool that iMobot could be a hero, but really, we just want to see it bust a move. Check out a video of our new robo love after the break.
Turing machine built from wood, scrap metal and magnets, 'geek' achievement unlocked (video)
We take it for granted nowadays that thumbnail-sized silicon chips can crunch through the most complex of calculations, but early last century, mathematical tasks were still being carried out by humans. It was around that time that one Alan Turing, Enigma code breaker and general computer science pioneer, came up with what was essentially a thought experiment, a mechanical machine capable of simulating and solving algorithms just like a grown-up CPU. Well, you know where this is going by now, one British software engineer decided to build just such a device, out of old bits and bobs he had lying around his geek lair, producing a working model that was recently shown off at the Maker Faire UK in Newcastle. The only downer, as he points out, is that it'd take "months to add two numbers together," but all good things start off humbly. Video after the break.
How the iPad 2 got thinner and lighter
Putting a device that is already thin and light onto a weight loss program seems like an exercise in futility, but it's something that Apple engineers love to do. The entire line of MacBooks has become lighter and thinner over the years, and many were surprised when the new iPad 2 weighed in a full 15 percent lighter than the original device. How did the Apple engineers accomplish this feat? Analysts at IHS iSuppli performed a detailed teardown and component cost analysis of the iPad 2 and found several factors that make the new iPad the light and thin supermodel of tablets. The iSuppli report mentions that Apple replaced the two batteries in the original iPad with three thinner cells that also allowed the removal of some internal plastic supports. In addition, the "fat" iPad had a stamped metal sheet that was part of the display. That metal is gone from the iPad 2, thanks to new glass technology that iSuppli speculates is from Asahi Glass of Japan. While shaving a few millimeters of thickness and grams of weight off of a new device might seem to be nitpicking, every bit of material that can be removed from the structure means less cost (and higher margins) for Apple, and even the slightly reduced shipping weight can result in cost savings for the company when multiplied over millions of devices. Plus, even though Apple got in trouble for saying just this, when it comes to these devices, you can't be too thin or too powerful. [via the New York Times]
LCD technology torn down and explained in the most lucid and accessible terms yet (video)
Look, we know you know all about LED backlights, light diffusion, subpixels, and the things that turn them on, but not everybody does. The humble LCD you're most likely reading this on still retains a level of mystery about the nitty gritty details of how it works for the vast majority of its users, so here's a terrific video breakdown of both its component parts and method of operation. Bill Hammack, a self-appointed Engineer Guy, takes us from the LED arrays that provide the light for most current LCDs, through all the filters and diffusers designed to make that light uniform, and into the ways thin film transistors make it possible for us to show moving color images of cats diving into boxes on such displays. It's exciting, deeply nerdy stuff, and it awaits your audience after the break.
Handheld millimeter / microwave camera to see through walls, your underpants (video)
You know those scanners that peep your naughty bits at the airport? Well, a team of researchers have been working on a handheld camera that sports the same technology, and while they're touting its future impact on stuff like cancer detection and aerospace engineering, we can't help but squirm thinking about its Peeping-Tom potential. The camera currently takes 30 images per second by transmitting millimeter and microwaves to a "collector" on the other side of a subject, and then sends them to a laptop for real-time inspection. Aside from being able to see straight through your BVDs, it can also be used to detect defects in spacecraft insulation, find termites lurking in the walls of your apartment, and help in the diagnosis of skin disease. The camera's creators are working on a smaller, one-sided version of the device that could have mass-market appeal -- we just hope this thing stays in R&D long enough for us to get our bikini bodies back. Check out a video of its G-rated abilities after the break.
Gold Capped: How to farm Maelstrom Crystals
Every week, WoW Insider brings you Gold Capped, in which Basil "Euripides" Berntsen aims to show you how to make money on the auction house, and Insider Trader, which is all about professions. Email Basil (new address is basil@wowinsider.com; old one no longer works) with your comments, questions or hate mail! The Maelstrom Crystal used to be disenchantable from an easily crafted epic. This was hotfixed, and the prices have unsurprisingly shot through the roof. People still want their gear enchanted, however, and for some reason these things keep appearing on the auction house. Where are they coming from? How can you get them? This article will discuss the current cheapest methods for getting them.
Lichborne: Professions for level 85 death knights
Every week, WoW Insider brings you Lichborne for blood, frost, and unholy death knights. Join World of Warcraft's first hero class as we head into a new expansion and shed the new kid on the block label. With your death knight at level 85 and all kitted out for raids, there's one more step you can take to make your death knight the best he can be: Learn some professions. A profession can provide self-buffs that nudge your DPS or suvivability up to the next level. It can grab you a lot of extra gold on the auction house (or drain all your gold, depending on which profession you take and how you choose to level it). Finally, it can provide you with some cool toys. This week, we'll take a look at WoW's professions to see which ones are tops for a death knight.
Toyota working on magnesium batteries for PHEVs of the not so near future
Toyota wants to take your range anxiety out for a walk behind the woodshed and obliterate it from the known world. The means for doing this, the Japanese giant has revealed, might very well be contained in its new magnesium-sulfur batteries, which promise to double the energy density of the current industry-best lithium ion cells. Of course, the catch here is that the new magnesium goodness is nowhere near ready and is projected to come in 2020 at the earliest, but we're gladdened to see a long-term view being taken by car manufacturers with regard to powering vehicles electrically. Alternative methodologies currently under review in Toyota's labs also include aluminum and calcium materials, showing that there is indeed no lack of ambition for making plug-ins respectable road warriors.
Arcane Brilliance: Professions for Cataclysm mages
Every week, WoW Insider brings you Arcane Brilliance for arcane, fire and frost mages. Except last week, when the holidays aggroed us. But rest easy, we managed to sheep the holidays, so now we can all go ahead and nuke down the rest of the year. As long as nobody breaks it early, our sheep shouldn't expire on the holidays for about 12 more months, give or take. So you're a mage. You have a job, and that job is taking something that was previously intact and converting it into much smaller, bloodier, often frozen chunks of that same thing. You manufacture shattered mobs, and you take pride in your work. But you may also have a side project or two. Maybe you thought to yourself, "Self, perhaps when we aren't making warlocks explode, maybe we should spend our time sewing trousers. Or baking cupcakes. Or making necklaces." Well, your self is right. You should be using your downtime in between vicious warlock kills to learn a side trade. They offer bonuses in the form of cool gear, extra money, and bonus stats, plus a bit of catharsis to help you decompress form all that murder. But which professions should you choose? That's easy: anything but mining. What's that? You'd like a bit more detail? Oh, fine.
Ancient acoustic engineers used stucco, drugs, and architecture to rock and confuse audiences
It's always fun when scientists discover new stuff about really old cultures, especially when it has to do with getting weird and rocking out. Recent research suggests temples built around 600 A.D. in Palenque, Mexico were designed with projection rooms that shot the sound of voices and instruments 300 feet away with the help of stucco-coated surfaces. 1600 years before that, in the Peruvian Andes, a pre-Incan society in Chavín was constructing a nightmarish Gallery of Labyrinths to play "strange acoustic tricks" during cult initiations: animal-like roars from horns, disorienting echoes, and maybe even choirs designed to produce otherworldly effects. And all of this while the poor inductees were being fed psychedelic San Pedro cacti. Yikes! To a certain extent this is all speculation, but we can tell you that if we were ancient priests with this kind of gear at our disposal we'd be using it for mind-controlling purposes too. Just because! [Photo adapted from Jenny Pansing's flickr]
Doctor Who's sonic screwdriver is still fiction -- but not forever
Kudos to Bristol University for catching our attention, and doing so in the name of promoting education. Professor of Ultrasonics Bruce Drinkwater is evoking a rather iconic name to better explain how cool science / engineering can be. Though already used in the manufacturing and medical fields -- don't yawn and look away just yet -- Drinkwater expresses some confidence that the future of this technology could very well usher in a pocketable device similar to the sonic screwdriver fancied by a certain former resident of Gallifrey. You know, that do-it-all device that can repair electronic equipment, burn and cut items, fuse metals, scan for information, and render virtually any lock useless... except here we're focusing on ultrasonic sound waves capable of fixing parts together and creating miniature force fields. As for the Time Lord himself, we know of at least one past Doctor who, as joked by a later incarnation, would rather "save the universe using a kettle and some string" (and has, in more recent iterations, pulled out miraculous victories with even a BlackBerry Storm). Point is, you should maybe consider a degree in Physics and an eccentric outfit should you ever find yourself holding a working prototype.
Spiritual Guidance: Professions for healing priests in Cataclysm
Every week, WoW Insider brings you Spiritual Guidance for discipline, holy and shadow priests. Dawn Moore covers healing for discipline and holy priests and is trying to find a good recipe for Lamingtons. Is everyone excited? How about anxious or intimidated? Cataclysm comes out tonight at midnight, and by tomorrow afternoon, everything will be different. Before you know it, there will be level 85 priests running about your respective realms and spam requests in trade chat for Inferno Rubies. Everyone's priorities are about to change -- but for now, we're still in the calm before the storm. In this calm, I though I'd focus on professions for priests. There have been a lot of small changes to professions that I think we need to give some attention before we get further invested in them. Plus, the start of the expansion is when professions get the most use, what with all that new, easily accessible gear. Let's get started.
Countdown to Cataclysm: Profession updates and changes
This article is part of our Countdown to Cataclysm series -- preparing you for Cataclysm launch one day at a time. Cataclysm is going to change the world of professions -- so without any further ado, here are the most important changes. General The skill cap for all professions is now 525. There is a lot of content locked behind a phased area you can not unlock until you're level 84. The new elemental trade goods are called Volatiles. Herbing and mining now provide experience. Archeology will be trainable. Guilds can see links for all members' available professions.
