Electric shocks could hold the key to manipulating dreams
Ever wanted to have more control over your dreams? A new study into how electricity affects the brain is enabling scientists to influence the way people sleep, giving hope that it could one day be used to improve the quality of your night's rest. By stimulating the frontal and temporal positions on volunteers' scalps, all of whom had never experienced lucid dreaming before, scientists were able to change the neural activity in their brains, bringing them towards a more "awake-like" state that could possibly allow them to control the outcome of their dreams.
European customers lose the Mac Pro on March 1, maybe earlier
Product safety regulations, how do they work? European regulators are requiring adherence to UL's 60950-1 second edition standards, which originally came into effect in late 2010. The rules cover power supply design and other technical specifications. As reported in Macworld, the Mac Pro's 2010-era design doesn't meet the new spec, and Apple is ceasing sales of the tower machine in Europe as of March 1 to comply with the regulatory cutoff. Tim Cook has previously said that 2013 will see a revamp of the heavy-duty Mac form factor, which currently offers expandability at the cost of modern I/O like Thunderbolt. Even though the Mac Pro could technically be sold for one more month, UK reader Terry Hall in Devon reports that his local retailer had already sent back all the Mac Pro inventory in stock. While it would be nice to think that we'll see an all-new Mac Pro before the end of Q1 2013, more likely that it will debut at WWDC this summer instead.
NASA captures red sprite, puts it in a jar
Lightning doesn't always shoot downwards. Just occasionally, a thunderstorm will be accompanied by a red sprite: a huge, momentary electrical explosion that occurs around 50 miles high and fires thin tendrils many miles further up into the atmosphere. Sprites have been caught on camera before, but a fresh photo taken by arty astronauts on the ISS helps to show off their true scale. Captured accidentally during a timelapse recording, it reveals the bright lights of Myanmar and Malaysia down below, with a white flash of lightning inside a storm cloud and, directly above that, the six mile-wide crimson streak of the rare beast itself. Such a thing would never consent to being bottled up and examined, but somehow observers at the University of Alaska did manage to film one close-up at 1000 frames per second back in 1999 -- for now, their handiwork embedded after the break is as intimate as we can get.
Cornell students steer Pong using brain waves, can't quite play during naps (video)
We here at Engadget are always fans of brain wave experiments, and so we were delighted when two Cornell University electrical engineering students, Chuck Moyes and Mengxiang Jiang, wrapped up a final project using brain waves in the best way possible: playing Pong. Their experiment links a baseball cap full of EEG-scanning electrodes to a computer, letting the cap wearer control a paddle using Alpha or Mu waves. Depending on the waves you use, you can move the paddle either by changing your concentration level or by thinking about moving your feet. You won't rack up a high score while napping (or with a teammate narrating over your shoulder), but with a budget under $75, it's hard to find fault. You can grab the source code below, and check out a video of Jiang and Moyes' handiwork after the break. [Thanks, Chuck and Mengxiang]
Belkin announces WeMo home automation system; controls electrical outlets with your smartphone, motion
If you're looking to control the electrical outlets of your home or apartment via your newfangled smartphone, Belkin has you covered. The company has unveiled the first two products of its newly launched WeMo line of home automation technology. The WeMo Home Control Switch is a plug that doubles as a programmable on / off for any device from lighting to coffee pots. Alongside the outlet power control, the WeMo Motion Sensor will detect your movement and when used in tandem with the Home Control Switch, can be programmed to power on electrical items in reaction to motion. Both pieces of the Belkin kit require the free WeMo app and will set you back $49.99 and $59.99, in order of mention. These two initial products will be available in the US in March, with more devices coming in the Fall.
MIT scholar builds a self-balancing unicycle to roll fast and furious around campus (video)
Sure, we've shown you the goofy SBU v2.0 unicycle, but what's better than a glorious DIY project? MIT student Stephan Boyer has built his own electrical uni-ride, which he's dubbing the "Bullet." The single-wheel transporter packs a custom MIG-welded steel body, two 7Ah 12-volt batteries, an ATmega328 chip and a 450-watt electric motor. While the Bullet isn't the speediest of solowheel demons (15mph max), it's on par with its $25,000 Ryno Motors counterpart. As far as power efficiency, the Bullet can go up to five miles on a single charge -- more than enough juice to hit a few classroom round-trips. There's some "Learning to Ride" tips from the creator himself at the source link, but in the meantime you can watch this unified purple rider in action after the break.
Scientists find less damaging defibrillation method, heart tissue relieved
Good news, aging Earthlings: a team of researchers have found a way to shock a coding patient's heart, while leaving other organs and tissues undamaged from the defibrillator. The device send a single high voltage pulse of electrical energy to a patient's chest in order to fix an irregular or nonexistent heart beat; traditionally, what often results is damage to point of contact and surrounding skin cells, muscles and tissues, but a team of whiz kids have seemingly figured out a way to dodge the dreadfulness. Led by scientists Stefan Luther and Flavio Fenton, the team claims that by using a series of five pulses of less potent shocks (instead of a single concentrated charge), docs can see an 84 percent reduction in damaging power. This new technology -- coined low-energy antifibrillation pacing (LEAP) -- can also be used in implanted defibrillators, not just the well-known flappy paddles. Due to the relatively low emissions, both the patient and such implants have extended lives. And that, friends, is good for us all -- given the impending Robot Apocalypse, we'll be needing those extra years just to hold down the fort.
IBM outs integrated circuit that's made from wafer-size graphene, smaller than a grain of salt
Lest you don't care what your circuits are made of, listen up: graphene's the thinnest electrical material, comprising just a single atomic layer. In addition to its electrical, thermal, mechanical, and optical properties, researchers dig it because it has the potential to be less expensive, more energy-efficient, and more compact than your garden-variety silicon. So imagine IBM's delight when a team of company researchers built the first circuit that fits all the components, including inductors and a graphene transistor, on a single wafer -- a setup that consumes less space than a grain of salt. The advantage, scientists say, is better performance than what you'd get from a circuit combining a graphene transistor with external components. In fact, the researchers got the circuit's broadband frequency mixer to operate at 10GHz , a feat that could have implications for wireless gadgets running the gamut from Bluetooth headsets to RFID tags. That's all just a layman's explanation, of course -- check out the latest issue of Science for the full paper in all of its technical glory.
Sensor vest promises to affirm that we're always stressed out
So maybe your stress level isn't sky high just yet, but even after an extended weekend, all it takes is that one email to get you right back where you were last Wednesday. As if you really needed something to tell you that (and if you don't have time to wait for Sweety to become a reality), a host of researchers have created a sensor-laden vest that will be able to inform wearers just how stressed they are. Developed as part of the EU's CONTEXT project, this sure-to-be-hip vest packs ultra-sensitive electrodes which register changes in muscle tension as individuals get more and more stressed, and in theory, letting someone know what's happening will allow them to simmer down before they further jeopardize their health (and the livelihood of colleagues, if you dig). Eh, we still prefer the Dr. Whippy method, honestly.[Via Talk2MyShirt, thanks Tony]
Electrical noise could help automate your home
For those building a house from the ground-up, installing a slew of cameras and touch panels to automate it may not be all that burdensome, but new research is hoping to use electrical noise to enable current homeowners to reap the benefits of home automation without tearing the walls back down. Put simply, the new technology would recognize noise whenever a denizen flipped on / off a household appliance, thus enabling the house to react by automatically switching on lights, heat, or music in that very room. 'Course, even the creators realize that it has limitations in its current state, namely that the house won't even flinch if you enter a room but don't interact with an appliance.[Via SmartMobs, image courtesy of KrayTracing]
Biopong enables workouts whilst gaming
If setting up your computer to play Pong with itself was beginning to incite a bit of jealously, fret not, as a recent project over at Teckjunkie can enable you to experience the famed title in an entirely new way. Aptly dubbed Biopong, this DIY endeavor relied on quite a bit of electrical engineering knowledge, a kit from ThinkGeek, and a steady flow of blood to your extremities. The rules are simple: flex either arm in order to interact with the game, and the uber-coordinated set may even be able to lift a few weights whilst gaming it up. Be sure to peep the video of this Wii exercise alternative after the jump.[Via Hack-A-Day]
Currently unused component found in Wiimote
Before you go running off to troll post on various message boards, we'd like to give you some specifics. A recent CNN technology feature details some of the various chips and components found within the forty-dollar Wiimote. Among the Bluetooth converters and accelerometers is a component listed as an "audio translator," which "converts analog data such as human speech into a digital data stream. This feature is unused now but will probably be employed in future games." The approximate cost is listed at $2.00.So, what's the deal? First, there is no actual microphone (a device capable of converting vibrational energy into electrical signals) found within the Wiimote. Though basic electrical engineering principals allow a standard speaker to act in such a fashion, the signal quality and frequency response would be unacceptably low. This chip actually requires an expansion device for it to be used at all. So why add it? It's only two dollars, but this rather unnecessary addition has cost the company several dozen million dollars. We can only assume that Nintendo or significant third parties are planning a title utilizing an expansion microphone, which will be presumably cheap enough to bundle with a title and incur no markup in price.God knows the masses need a mainstream karaoke game (we know about Karaoke Revolution for the PS2, but it never really took off), and the Wii is just the system to do it. Like a Virginnnnn ... hey!
