New quantum tunneling transistors to make PCs less power-hungry
Yes, that awesome new 8-core chip in your PC is the fastest thing on the block, but it's got your utility meter spinning accordingly. Fortunately, researchers from Penn State have come up with a new high performance transistor that may turn future chips from power hogs into current-sipping silicon. The group, in cooperation with semiconductor manufacturer IQE, has created a high-performance transistor capable of significantly reducing power demand whether it's idle or switching. Doctoral candidate Dheeraj Mohata's the one who made it happen by inventing an alternative to traditional MOSFET (metal-oxide semiconductor field-effect transistors) technology capable of turning on and off using far less power. Mohata's method uses a tunneling field effect transistor crafted from dissimilar semiconductor materials to provide instant on-off capability at 300 millivolts -- compared to MOSFET's one volt requirement -- to provide a power savings of 70 percent. You can dig deeper into the technical transistor details at the source, but all you really need to know is that the ladies love a PC with paltry power consumption.
Lyneborg bot carves models of magnetic fields, dares the future to have a look (video)
If you're going to create a robot that carves something, have it carve models of an invisible field. This is what Frits Lyneborg, creator of the Yellow Drum Machine, has done with a new homemade bot that uses a combination of motors, pulleys, small drills, makerbeams and magnetic sensors. The end result is a robot that, when combined with the interpretative software, can literally read a magnetic field and move the robot's components to cut an accurate model from a crumbly-yet-strong material known as 'Oasis Brick.' You can witness the magic yourself in a video after the break, and if you've any advice for making it better, drop Frits a line there in the via link.
Nuclear clocks could be 60x as accurate as atomic counterparts, less prone to errors
For years, atomic clocks have been considered the most accurate devices for tracking the slow march towards obsolescence, a subatomic particle vibrating a given number of times per second with relatively few issues. Now the reliability crown might be passed to the nuclear clock, which in addition to sounding gnarly, could prove to be less susceptible to errors from outside stimuli. It goes like this: although an atomic clock will measure a certain number of vibrations per second, external forces such as ambient electric and magnetic fields affect the electrons used in atomic clocks, causing mishaps. The particles used in nuclear clocks that are measured for vibrations -- and thus timekeeping -- can be excited with a relatively low-energy ultraviolet light, allowing for fewer variations from the aforementioned fields. To wit, Corey Campbell and colleagues at the Georgia Institute of Technology in Atlanta have devised a scheme that uses lasers to carefully control the spatial orientation of the electron orbits in atoms. A nuclear clock containing a thorium nucleus controlled in this way would drift by just one second in 200 billion years, the team claims. Before nuclear clocks become a reality, researchers must identify the precise frequency of light needed to excite thorium nuclei; but this is what grad students are for, right?

Pepsi's 'Sound of Football' project lets visually impaired players see the pitch with their ears (video)
One one side of the field was a team of former pro soccer players. On the other, a squad of visually impaired amateurs. The two sides laced 'em up, stretched out their quads and went head to head in a scrimmage, though the matchup was a lot more even than you might expect. It's all part of something called the "Sound of Football" -- the latest experiment from the Pepsi Refresh Project. The idea was to level the playing field, so to speak, by forcing both teams to play a match using only their ears, and a pretty nifty tracking system. Created by Tracab, this system was comprised of 16 cameras covering the entire pitch (including two stereovision cameras placed at mid-field), and used jersey colors to distinguish the home team from the away team, and to identify the referees. This set up, which was deployed during the last World Cup, essentially tracked the position of each player in real-time. This information was then funneled into an iPhone attached to each player's headset, and converted into a surround-sound landscape, using an app created by a company called Society 46. Unique sounds were assigned to both the ball and the goal; turning your head in the direction of one goal would produce one sound, facing the ball would result in another. This allowed each player to get a better idea of his surroundings and of his spatial positioning, though, as many of the pros found out, it wasn't quite as easy as it looked. The designers of this system are now looking to use their technology in other, non-sports arenas, in the hopes of helping the blind and visually impaired "see" more of the world around them. Check out a pair of videos on the match and the technology behind it, after the break. [Thanks, Martin]
Lost Pages of Taborea: Resource acquisition
Way back when Runes of Magic was still young and learning to fly, there was only one way to obtain resources: Find a resource node and click it. Come to think of it, I've always chopped wood and gathered herbs, but what's the proper verb for obtaining ore in MMOs? In any case, the tried and true method of clicking on resource nodes has always worked for RoM. It's just that recipes take a lot of resources, which used to mean a lot of gathering. Seriously. A lot. I've written about the state of RoM's crafting system before, but many updates have come along since then. While the large amount of resources needed to craft items hasn't changed, the many different ways of obtaining those resources have. In this article I cover all the new ways you can get your grubby little mitts on a crafter's best friend.
Argent Tournament Dailies: A Valiant's Field Training
This is one of the quickest and easiest dailies to complete for your Argent Tournament prestige. The questgiver asks simply that you kill 10 Scourge units in Icecrown.Remember, in 3.1 any mob that will grant you quest credit will show as much on their tooltip when you mouseover them. Use this to your advantage and don't waste your time with an AOE pack that won't give you credit!Given its close proximity to the Tournament grounds, many players are likely to flock to Sindragosa's Fall to kill the Scourge mobs there, including Frostbrood Whelps and Cultist Corrupters. You have some other choices, though -- the Valley of Lost Hope is chock-full of mobs that grant quest credit, as is Aldur'thar, and both are close enough to the Grounds that you don't need to fly all around the zone just to get your quest done. Crack some Scourge skulls and grab your reward!Reward: 1 Valiant's Seal and 13g 23s Editor's note from Alex Ziebart: I happen to like doing the Shadow Vault dailies side-by-side with this one. The vrykul for Leave Our Mark count as Scourge for this quest!
Pittsburgh's Heinz Field to get $2.4 million HD scoreboard in 2007
Oh boy, there's yet another contender in the "world's largest" HDTV race, and per usual, it's at a sports-related venue. This time around, Pittsburgh's Heinz Field is getting ready to see a high definition makeover as it seeks to replace the aging SD screen that has stood since the stadium opened in 2001. The new HD display, which will be manufactured by Daktronics, should be fully installed and ready to go for the 2007 Steelers' season, and will reportedly enable an additional 3,600 ticket holders who can't see the current board due to a viewing angle snafu to get a glimpse of those beautiful HD replays. Notably, no details were present about the exact resolution, screen size, or any other specifications of the sure-to-be-mammoth board (as is the case on the forthcoming screen to be built in the Washington Nationals Baseball Stadium), but it won't be too long before we'll get to gaze at this bad boy in person, anyway.
