Nokia Aknowledging Fanboy Concept Work

For ages, fanboys have pumped out concept renderings of different products and stamped a well-known corporate name on them to lend an air of legitimacy. The worst of these have been pure flights of fancy with no attention paid to "design DNA"—some of the more ridiculous faux-Apple-branded concepts come to mind—while the best have incorporated well-recognized design elements, using a certain angle here, the proper font there, to suspend disbelief.

Sony Open Planet Ideas Winner - Greenbook: Giving you that extra push to do some good

Say you're sitting around on a Saturday, with no obligations other than bumming around the house and poking at old projects you've been "meaning to get to" for months. You debate the idea of actually doing something meaningful with your weekend, maybe even with some quick volunteer work, but where do you go? Even if you had considered this on some Saturday, the extra effort required to identify a volunteer organization might have burned away any energy you were ready to expend.
Ay, there's the rub: How can people quickly and easily connect with the thousands of charities, nonprofits and groups they might want to help, even for just a few hours?
Paul Frigout considered this problem and created Greenbook, the winning concept from the Sony Open Planet Ideas Challenge.

AMD Radeon HD6790 Review : GTX550 Ti Killer?

The HD 6790 is set to beat the GTX550 Ti, which is quite a failure by nVidia, performing even worse than the previous generation's GTX460. It is based on AMD's 40 nm "Barts" GPU which is the very same graphics processor used in the Radeon HD 6850 and HD 6870. Next to that this product comes with a full 256-bit wide memory bus giving it very nice memory bandwidth and really, aside from slicing some shader processor clusters and ROPs away, this is a R6800 series card.

Armed with plenty of power for a products in the 125 EUR (RM544) range this product could be just what the doctor ordered for gamers on a budget, have a quick peek at the actual reference sample and then let's head on over into the review.

SparkFun intros IOIO for Android, a hack-free breakout box to get your mind spinning (video)

Meet any seasoned techie, and they'll likely spin whimsical tales of computing's early days, and the challenge of finding a practical use for a device with seemingly limitless potential (you know, like feeding your cat while you sleep). A new product from SparkFun promises to bring this old-school awesomeness into the smartphone age: introducing IOIO (pronounced yo-yo), a breakout box that enables any Android 1.5+ device to control electronic circuits from within Android's applications. Designed in collaboration with Google, Spark's PCB connects to your phone over USB, working its magic through a Java library that hooks into your apps. This DIY paradise will begin shipping in a few weeks, and can be yours for $49.95 on pre-order. We've already witnessed some clever mods with IOIO, and when it sent a real alarm clock ringing, we couldn't help but smile. Crack one yourself after the break.

AMD Radeon HD6990 vs nVidia GTX590

A short history lesson on dual GPU cards.

Most consumers don't even need dual GPUs with single GPUs more than enough for gaming purposes. However, some people like to be extreme, and dual GPU cards are the most extreme cards one can buy in the market. Right now we are looking at dual GF110 and dual "Caymans", essentially giving you two slowed down GTX580 or two HD6970 respectively.

ASUS Rampage III Black Edition

If one thing is a fact then it's that the X58 chipset is technology that keeps on living on the edge. Quick match tells me that the X58 chipset is now roughly two and a half years old. And it is still alive and very much kicks ass big-time! While P67 for Sandy Bridge is the equivalent kickass product, the X58 based motherboards give you some advantages, and that would be the Core i7 socket 1366 processor, including the 6-core Nehalem based processors of course.

Apple exploring hybrid e-ink/LCD display for iDevices

A recently published patent application suggests Apple is exploring ways to incorporate e-ink display technology into its iPhone, iPad, and iPod touch. And unlike other e-ink devices, Apple's hybrid system would be able to display sharp text in a range of lighting situations without sacrificing the ability to display full color, video, and graphics.

The application, Systems and Methods for Switching Between an Electronic Paper Display and a Video Display, was originally filed in October 2009. It describes a hybrid system that employs a combination of "electronic paper" with a more traditional color LCD or OLED display to gain the advantages of both display types.

Nanoparticles successfully take down MRSA bacteria

Traditional antibiotics like doxycyclin and vancomycin—the kind that many bacteria can now resist because of their overuse—work by getting inside the bacterial cell and interfering with essential cellular processes. Charged peptides have been proposed as alternatives, since they work by electrostatically interacting with the negatively charged bacterial cell wall, poking holes in the bacterial cell membrane and thereby killing the bacteria.

Nederberg et al. made charged polymers out of cyclic carbonates, which are nontoxic and biodegradable. Their degradation produces alcohol and carbon dioxide, and they degrade slowly, so they have prolonged antimicrobial functions inside the body and long shelf-lives outside of it. Because of their amphiphilic nature—they have a positively charged region, which is hydrophilic, but also a hydrophobic region—these nanoparticles spontaneously form small spheres in water, so they can hide their hydrophobic parts inside.

The nanostructures were effective against Gram-positive bacteria, methicillin-resistant Staphylococcus aureus (MRSA), and the fungus Cryptococcus neoformans, and had an efficiency comparable to that of conventional antimicrobials at their best, all while leaving red blood cells alone.

When injected into mice, the antimicrobial nanoparticles did not exhibit any significant toxicity over the test period, which lasted for fourteen days. It's not yet exactly the nanotechnological immunomodulation described by Neal Stephenson in The Diamond Age… but it's getting close.

Symbian Is No Longer Open Source

Nokia recently clarified via a blog post the status of Symbian's code. Though Symbian was an open source platform in the past, it no longer is. That doesn't change the fact that it continues to be available under license to hardware makers and software developers so that new products can be brought to market. Nokia said it will continue to work with its OEM and developer partners, but those parties will no longer be able to contribute back to the Symbian source code. Nokia said, "The Nokia Symbian License is an alternative license which provides an access to Nokia’s additional Symbian development for parties which collaborate with Nokia on the Symbian platform."

Study: Computer Gamers less likely to go to a University

A recent study at the University of Oxford indicates that those who play computer games are less likely to reach University level education.

As ZDNet reports, those who play video games on a regular basis and who have little or no other extracurricular activities were found to have slim chances of going to a University. Both males and females suffered a 5% drop in their likelihood of attending a University.

However, those who read a book for pleasure, spent some time at a movie theater watching a movie, or participated in something artistic at least once a month, had a higher chance of attending a University.

However, there is one thing to note. This study uses data from 1970 to the present. Gaming has changed over the years with the inventions of the Wii and the Xbox Kinect. Games are now more brain stimulating rather than one-dimensional. If Mr Taylor used current data reflecting the change in the gaming climate from the past few years, perhaps his findings might be a little different.

Mercedes-Benz debuts tablet-packing A-Class concept (video)

As fond as we are of the A-Class, it's never been the best looking Benz in the bunch, but with the introduction of the new A-Class concept, it looks like that could soon change. One of the car's designers describes it variously as sexy, expressive, and beautifully formed, and while we wouldn't go quite that far, we have to say it's not too shabby. The car sports some interesting looking LED headlights and an inverted mesh grill on the outside, and on the inside it's packing a rather futuristic display, complete with a dash-mounted tablet and what looks to be an iPhone protruding from the center console. Now, there's no guarantee that this thing will get the E-Cell treatment, or that all the bells and whistles will make it to production, but for now, it's shaping up to be a rather stylish upgrade. For more Mercedes-Benz eye candy, check out the gallery below.

iPhone 5 to come with 8 megapixel camera, Sony CEO accidentally reveals

While speaking to Walt Mossberg this week, Sony CEO Howard Stringer has apparently accidentally shed some light on the camera hardware specifications of the iPhone 5. As Stringer was discussing the impact of the Japanese earthquake on the company’s CMOS sensor production, he allegedly said: “Our best sensor technology is built in one of the affected factories. Those go to Apple for their iPhones… or iPads. Isn’t that something? They buy our best sensors from us?”
This is interesting because Apple does not currently use Sony cameras in their products. Analysts at The Street (the people who previously accurately predicted the 5 megapixel iPhone 4 camera) are now saying that the fifth-gen iPhone will be using a 8-megapixel camera from Sony, which also coincides with rumors that Apple is seeking to move away from the iPhone 4 camera supplier OmniVision for a new supplier.

Israeli parody details the rise and fall of Apple's iBoy, humanity as a whole (video)

For those unaware, Eretz Nehederet is effectively the Israeli equivalent to The Onion, and on the 1st of April, they covered the hardest-hitting piece of Apple news to cross their news desk in quite some time. That news, friends, is the iBoy. Available in a variety of skin tones, religious beliefs and languages, this iPad-adorned human is both the best and worst thing to happen to mankind... well, ever. There's no word on when it'll be on sale, but it's fairly clear that "divorce" and "alcohol" are about to take a backseat to this guy when studying factors that rip families to shreds. Click and weep as you see fit.

Stealth unveils the LPC-670 mini-PC: small in size, vast in price

Stealth has been in the compact computing game for some time, and the company has just rolled out its most powerful pint-sized PC to date, the LPC-670. Packing Intel's Arrandale Core i5-520M, Core i5-580M, or Core i7-620M silicon, up to 8GB DDR3 RAM, a DVD or Blu-ray burner, a max 750GB 2.5-inch HDD or 128GB SSD, optional 802.11g WiFi, gigabit Ethernet, HDMI and DVI connections, Stealth's new mini-PC has the brawn of much bigger machines. The price of such lilliputian luxury? An account-emptying $1650, and that's just for the base model -- check the right option boxes and the final tally will run you over three grand. That should ensure the customer base will be just like the machine itself... tiny.

Editorial: Android's problem isn't fragmentation, it's contamination

This thought was first given voice by Myriam Joire on last night's Mobile Podcast, and the simple, lethal accuracy of it has haunted me ever since. All the hubbub and unrest about whether Google is trying to lock Android down or not has failed to address whether Google should be trying to control the OS, and if so, what the (valid) reasons for that may be. Herein, I present only one, but it's arguably big enough to make all the dissidence about open source idealism and promises unkept fade into insignificance.

Sony's Jack Tretton says Nintendo makes 'babysitting tools'

Sony does what Nintendon't? That's the general sentiment from a brief interview that PlayStation chief Jack Tretton gave to Fortune this week, in which he talked up Sony's strengths and played down (some may even say belittled) its competitors, and Nintendo in particular. That began with the relatively tame assertion that Sony's decision to go high-end with PlayStation 3 is just now beginning to pay off while the other consoles are "starting to run out of steam," before he took aim at Nintendo's handheld business. According to Tretton, Nintendo's handhelds all offer what he calls a "Game Boy experience," something that's great as a "babysitting tool," but that "no self-respecting twenty-something is going to be sitting on an airplane with one of those."

Alienware M14x manuals leak out, confirm the gaming notebook once and for all

Just yesterday Dell's leaky website poured out details about the upcoming Alienware M11x R3 gaming notebook, and it didn't take long for its larger brother to follow suit -- today, we've got the full user and factory service manuals for Alienware's M14x, confirming a number of juicy rumors. Unfortunately, there's no mention of a Full HD 1080p LCD screen for the 14-inch visitor from another planet, but there will apparently be both 1366 x 768 and 1600 x 900 options on tap, both driven by NVIDIA's GeForce GT555M switchable Optimus graphics with up to 3GB of dedicated memory. Of course, you'll also find Intel's latest Core i5 and i7 Sandy Bridge CPUs and up to 8GB of RAM, Gigabit Ethernet, SATA 6Gbps and optional 3G / 4G connectivity, optional WirelessHD, a two megapixel webcam, and even a 8-cell, 63Whr battery to make portable gaming vaguely possible. Hit up our source link to see how Dell put this machine together -- and how you can tear it apart -- while we wait for the company to finally make the smokin' hot notebook official, and let us know how just badly our wallets will feel after it rips their innards out.

Sprint radar imaging system peeps inside walls, floors to detect bombs, tell-tale hearts

Back in 2005, we reported on a little something called the Prism 200, which allowed its holder to essentially see what folks were doing on the other side of a wall. Since then, we've seen plenty of devices that boast the same claims, but it wasn't until recently that the makers of the Prism 200 created a device that can actually see inside those walls. Looking something akin to an old school punch clock, Cambridge Consultants' Sprint in-wall radar imaging system provides 3D renderings of items embedded in walls, floors, and even ceilings. Where as existing X-ray systems require access to both sides of a wall, Sprint's radar setup allows users to see what's going on inside without dual access. As you might imagine, Cambridge is pushing this thing as a security tool, allowing for detection of bombs, drugs, dead bodies -- you know, the usual bad guy stuff. Sprint is currently undergoing testing. Full PR after the break.
