New imaging technique allows quick evaluation of graphene sheets

Posted on by

Graphene based sheets such as pristine graphene, graphene oxide, or reduced graphene oxide are basically single atomic layers of carbon network. They are the world's thinnest materials. A general visualization method that allows quick observation of these sheets would be highly desirable as it can greatly facilitate sample evaluation and manipulation, and provide immediate feedback to improve synthesis and processing strategies. Current imaging techniques for observing graphene based sheets include atomic force microscopy, transmission electron microscopy, scanning electron microscopy and optical microscopy. Some of these techniques are rather low-throughput. And all the current techniques require the use of special types of substrates. This greatly limits the capability to study these materials. Researchers from Northwestern University have now reported a new method, namely fluorescence quenching microscopy, for visualizing graphene-based sheets.

Rad Blaster Mini Boombox is the Freshest MP3 Player and Flash Drive Around [Portable Media]

Posted on by

The Rad Blaster does what a lot of MP3 players do—like play music, record sounds and store files. But this one does it shaped like a boombox. Like a BOOMBOX people.

Rad Blaster also includes a 1.1-inch OLED screen and 2GB of built-in memory. It's certainly bigger than a shuffle, but it doesn't sound like a bad deal for $60. I mean, can you breakdance to a shuffle? I think not. [Rad Blasters]



The Graphics Cards You Should Buy at Every Price [Graphics Cards]

Posted on by

Choosing a graphics cards is a confusing endeavor. So Tom's Hardware shared their buying results after testing pretty much every card on the planet. Whether you've got $50 to spend or $250 to spend, this list will come in handy:

Some Notes About Our Recommendations

  • This list is for gamers who want to get the most for their money. If you don't play games, then the cards on this list are more expensive than what you really need. We've added a reference page at the end of the column covering integrated graphics processors, which is likely more apropos.
  • The criteria to get on this list are strictly price/performance. We acknowledge that recommendations for multiple video cards, such as two Radeon cards in CrossFire mode or two GeForce cards in SLI, typically require a motherboard that supports CrossFire or SLI and a chassis with more space to install multiple graphics cards. They also require a beefier power supply compared to what a single card needs, and will almost certainly produce more heat than a single card. Keep these factors in mind when making your purchasing decision. In most cases, if we have recommended a multiple-card solution, we try to recommend a single-card honorable mention at a comparable price point for those who find multi-card setups undesirable.
  • Prices and availability change on a daily basis. We can't base our decisions on always-changing pricing information, but we can list some good cards that you probably won't regret buying at the price ranges we suggest, along with real-time prices from our PriceGrabber engine, for your reference.
  • The list is based on some of the best U.S. prices from online retailers. In other countries or at retail stores, your mileage will most certainly vary.
  • These are new card prices. No used or open-box cards are in the list; they might represent a good deal, but it's outside the scope of what we're trying to do.

ROPs:16
Memory Bus:128-bit
Core Speed MHz:600
Memory Speed MHz:400 (800 effective)
DirectX/Shader Model:DX 10.1/SM 4.1

You will not find a card that packs more punch than ATI's Radeon HD 4650 under the alluring $50 price point. With solid stock performance and an overclockable GPU, this card is an excellent starting point for our recommendations, and a wholly worthwhile upgrade if you're currently stuck using a motherboard with integrated graphics.

Best PCI Express (PCIe) Card For ~$65: Tie

Radeon HD 4670 (Check Prices)

Good 1680x1050 performance in most games

Radeon HD 4670

Core Speed MHz:750
Memory Speed MHz:1,000 (2,000 effective)
DirectX/Shader Model:DX 10.1/SM 4.1

With the release of Nvidia's GeForce GT 240, ATI's Radeon HD 4670 is no longer the most powerful reference card without a dedicated power connector. However, it remains a compelling solution under the $75 price point, which Nvidia's solution simply hasn't hit yet.

Performance is excellent and power usage is very low, making this product an impressive performer all-around. Its accelerated clock rates and modestly-higher price tag are worth considering if you originally had your eye on the Radeon HD 4650.

GeForce 9600 GSO (Check Prices)

Good 1680x1050 performance in most games

GeForce 9600 GSO
Codename:G94/G92

Core/Shader Speed MHz:550/1,375
Memory Speed MHz:800 (1,600 effective)
DirectX/Shader Model:DX 10/SM 4.0

The GeForce 9600 GSO is seems to be getting quite hard to find, and is likely being end-of-life'd soon in favor of the new GeForce GT 240. Nevertheless, as long as it is available, the GeForce 9600 GSO remains a powerful competitor compared to the Radeon HD 4670. While the GeForce requires a dedicated PCIe power connector to supply more juice than the Radeon, it does offer better performance in some situations.

Best PCIe Card For ~$85:

GeForce 9600 GT (Check Prices)

Good 1680x1050 performance in most games

GeForce 9600 GT

Memory Bus:256-bit
Core Speed MHz:650
Memory Speed MHz:900 (1,800 effective)
DirectX/Shader Model:DX 10/SM 4.0

The GeForce 9600 GT is a great performer, thanks in part to its high-end 256-bit memory interface and speedy DDR3 memory. It's a great choice on an $85 budget, even if the architecture on which it centers is showing its age.

Certainly, this card's continued presence here is a testament to Nvidia's engineering work dating back almost two years ago. With that said, we'd certainly like to see the company's latest DirectX 10.1 cards drop in price to compete against ATI's strong offerings.

Best PCIe Card: ~$90 To $140

Best PCIe Card For ~$95: Tie

GeForce 9800 GT (Check Prices)

Exceptional 1680x1050 performance in most games, 1920x1200 in most games with lowered detail

Core/Shader Speed MHz:650/1,625
Memory Speed MHz:1,000 (2,000 effective)
DirectX/Shader Model:DX 10/SM 4.0

The GeForce 9800 GT is essentially a rebadged GeForce 8800 GT, and offers the same great performance it has for years now (that sure sounds funny to say in reference to graphics cards).

With the rising price of ATI's Radeon HD 4850 giving it space to breathe, this legendary card is once again a recommended buy. But once again, we're looking forward to seeing technological progress put new, faster, and cooler products loaded down with more features in this space rather than revisiting history.

Fortunately, there's still PhysX and 3D Vision support to like about this aging board.

Radeon HD 4830 512MB (Check Prices)

Exceptional 1680x1050 performance in most games, 1920x1200 in most games with lowered detail

Memory Bus:256-bit
Core Speed MHz:575
Memory Speed MHz:900 (1,800 effective)
DirectX/Shader Model:DX 10.1/SM 4.1

Just as the GeForce 9800 GT can once again be recommended due to the rising price of the Radeon HD 4850, so can the Radeon HD 4830. While availability is low, this Radeon is still a viable option under the $100 price point if you can find it. You'll discovered that it offers great performance on par with the GeForce 9800 GT, with the added benefit of DirectX 10.1 support.

Best PCIe Card For ~$110:

GeForce GTS 250 512MB (Check Prices)

Good 1920x1200 performance in most games

GeForce GTS 250 512MB

Memory Bus:256-bit
Core/Shader Speed MHz:738/1,836
Memory Speed MHz:1,100 (2,200 effective)
DirectX/Shader Model:DX 10/SM 4.0

The dissapearance of the $100 Radeon HD 4850 has not only opened up the GeForce 9800 GT and Radeon HD 4830 for recommended status, but also the GeForce GTS 250.

At $110, the 512MB version of this card offers respectable performance, and nothing else in the price range can compare to it. As fast as the Radeon HD 4850 and new Radeon HD 5750 (and notably cheaper), the GeForce GTS 250 has no real competition from the rest of the sub-$150 market at this time.

Bear in mind that going this route instead of the Radeon HD 5750 will cost you DirectX 11 support and Eyefinity. But in the context of gaming, you'll need to make other quality sacrifices long before trying to enjoy either value-add in the $110 range.

Best PCIe Card For ~$120:

GeForce GTS 250 1GB (Check Prices)

Good 1920x1200 performance in most games

GeForce GTS 250 1GB

Core/Shader Speed MHz:738/1,836
Memory Speed MHz:1,100 (2,200 effective)
DirectX/Shader Model:DX 10/SM 4.0

For $10 more than the 512MB version, an interested gamer can get the benefit of a full gigabyte of memory. At the highest resolutions and levels of anti-aliasing, this extra memory might provide a performance boost, though it's unlikely the GeForce GTS 250 is powerful enough to run at those detail levels. Still, many buyers might find the slight $10 price increase worthwhile in something like Grand Theft Auto IV.

Best PCIe Card: ~$150 To $290

Best PCIe Card For ~$155: Tie

Radeon HD 5770 (Check Prices)

Core Speed MHz:850
Memory Speed MHz:1,200 (4,800 effective)
DirectX/Shader Model:DX 11/SM 5.0

While the new Radeon HD 5770 isn't any faster than its older Radeon HD 4870 cousin (we've found that it's even slightly slower in many instances), it does have something the Radeon HD 4870 doesn't have: full DirectX 11 and Eyefinity support. Indeed, while the Radeon HD 5770 doesn't run away with any performance crowns in this category, it does look good from a longevity/value standpoint.

ROPs:28
Memory Bus:448-bit
Core Speed MHz:576
Memory Speed MHz:999 (1,998 effective)
DirectX/Shader Model:DX 10/SM 4.0

Like many cards, the GeForce GTX 260 is becoming very hard to find, and may soon be end-of-life'd. In any case, it does offer advantages in titles that run better on Nvidia's GT200 architecture, and it sports some GeForce-only value-added features like PhysX compatibility and support for GeForce 3D Vision.

Once again, a little diligence is required on the part of the buyer to find out which card is best adapted for his or her favorite titles, and whether or not your motherboard supports SLI, CrossFire, or both multi-card technologies.

Best PCIe Card For ~$200:

Radeon HD 4890 (Check Prices)

Excellent 1920x1200 performance in most games

Core Speed MHz:850
Memory Speed MHz:993 (3,900 effective)
DirectX/Shader Model:DX 10.1/SM 4.1

The Radeon HD 4890 is essentially an overclocked Radeon HD 4870. However, the tweaks that AMD made to the newer RV790 die result in much higher overclocking headroom. At stock speeds, this card is worth the $200. But to get the most out of it, some overclocking is in order. And now that the prices on Radeon HD 5850 cards are through the roof, there's not much between this board and ATI's next-fastest solution.

Core/Shader Speed MHz:738/1,836
Memory Speed MHz:1,100 (2,200 effective)
DirectX/Shader Model:DX 10/SM 4.0

Two GeForce GTS 250 cards in SLI pack a punch and make a strong case for multi-card setups. With the Radeon HD 4850s going up in price and down in availability, these GeForce cards replace them as the weapon of choice for sub-$300 brute force power.

Best PCIe Card: ~$300 To $400

Best PCIe Card For ~$310: None

Honorable Mention: Radeon HD 5850

Exceptional 1920x1200 performance, 2560x1600 in most titles

DirectX/Shader Model:DX 11/SM 5.0

The new Radeon HD 5850 has some definite advantages over a pair of GeForce GTX 260s in SLI or a pair of Radeon HD 5770s in CrossFire. It doesn't need a CrossFire-compatible motherboard, it uses a lot less power thanks to its 40nm manufacturing process, and it sports DirectX 11 capabilities (plus Eyefinity).

Unfortunately, scant availability forces us to relegate the Radeon HD 5850 to Honorable Mention status until it can be purchased without having to fight for it.

Read our full review of ATI's Radeon HD 5850 for more information on the card and its accompanying architecture.

Best PCIe Card For ~$330: Tie

At approximately the same price, these options retain the same advantages of their single-card counterparts: two GeForce GTX 260s offer SLI compatibility, PhysX, and GeForce 3D Vision support, and two Radeon HD 5770s offer DirectX 11, Eyefinity, and high-def audio bitstreaming to CrossFire-compatible motherboard users. A good case can be made for either of these options, and none of them are a poor choice. Just pick your poison.

2 x GeForce GTX 260 in SLI (Check Prices)

Memory Bus:448-bit
Core Speed MHz:576
Memory Speed MHz:999 (1,998 effective)
DirectX/Shader Model:DX 10/SM 4.0

Nvidia doesn't have a DirectX 11-class architecture yet, so if you're going to sink $300+ into DirectX 10 hardware, do so knowing that there are competing DirectX 11 boards available in the same price range.

A pair of Radeon HD 5770s won't offer quite the same level of performance as two GeForce GTX 260s in SLI; that's the trade-off for more modern functionality, though.

2 x Radeon HD 5770 in CrossFire (Check Prices)

DirectX/Shader Model:DX 11/SM 5.0

The new Radeon HD 5770 sports added benefits over its GeForce GTX 260 competition: DirectX 11, triple display outputs, and the ability to bitstream high-definition audio content from Blu-ray movies contribute significant value to ATI's newest mainstream graphics cards. For those seeking long-term DirectX 11 compatibility, this might be the more attractive option.

Two Radeon HD 4890 cards should, on average, perform on par or better than a single GeForce GTX 295, and will definitely beat out a single Radeon HD 5870. Plus, these Radeons cost less than either option. If you have a CrossFire-compatible motherboard and want some serious performance at high resolutions, this route is the way to go.

For $10 less, a couple Radeon HD 4890s will easily beat a single Radeon HD 5870 in the titles that matter today (perhaps this will change when DirectX 11 software becomes more pervasive). From a raw price/performance standpoint, this makes the Radeon HD 5870 a hard sell. But that is not to say this card is underpowered: it sports the fastest single GPU on the planet, relatively low power usage (remarkably low at idle), and DirectX 11 support. For folks without a motherboard that supports CrossFire and a hefty power supply, the new Radeon HD 5870 is definitely a more-than-viable option. Unfortunately, availability is still quite rare.

Despite ATI's new Radeon HD 5970 taking its place as the fastest graphics card on the planet, Nvidia's GeForce GTX 295 (with SLI-on-a-board) remains an extremely powerful graphics card. Essentially two conjoined GeForce GTX 275s, the GeForce GTX 295 offers very notable gains over a single Radeon HD 5870 in the great majority of game titles, although the Radeon will use far less power doing so. The GeForce GTX 295 does have an advantage in that it it still quite easy to find and purchase. Moreover, ATI's release has forced prices on these cards down by a significant chunk.

3,200 shader processors. There isn't much more we need to say about the brutal grace of execution that characterizes the world's fastest graphics card, the Radeon HD 5970. With two Radeon HD 5870 GPUs onboard, the only things we can complain about are scant availability and an extremely high price tag. Availability should improve over time; the price not so much, but if you're in the market for this card price probably isn't an issue.

Read our full review of ATI's Radeon HD 5970 for more information on the card and its accompanying architecture.

There you have it folks; the best cards for the money this month. Now all that's left to do is to find and purchase them.

Don't worry too much about which brand you choose, because all of the cards out there are close to Nvidia's and ATI's reference designs. Just pay attention to price, warranty, and the manufacturer's reputation for honoring the warranty if something goes wrong.

Also remember that the stores don't follow this list. Things will change over the course of the month and you'll probably have to adapt your buying strategy to deal with fluctuating prices. Good luck!



Operation Chokehold: A Plan to Destroy AT&T This Friday [At&t]

Posted on by

This "Apple memo" that appeared mysteriously on Fake Steve Jobs' site plans an all-out iPhone attack on AT&T's network this Friday, December 18 at noon Pacific:

Subject: Operation Chokehold
On Friday, December 18, at noon Pacific time, we will attempt to overwhelm the AT&T data network and bring it to its knees. The goal is to have every iPhone user (or as many as we can) turn on a data intensive app and run that app for one solid hour. Send the message to AT&T that we are sick of their substandard network and sick of their abusive comments. The idea is we'll create a digital flash mob. We're calling it in Operation Chokehold. Join us and speak truth to power!

You could join this flashmob to bring AT&T "to its knees," but from what I can tell, it's already there. [Fake Steve]



Meet the New Neighbors: Earth-Like Worlds Orbiting Nearby Stars | 80beats

Posted on by

exoplanet220As the tally of known planets beyond our solar system continues to grow, so does the number of them that look familiar—planets close to Earth’s size around stars that resemble our sun. Today astronomers announced that they’ve found a new batch of planets that not only fit that description but also reside in our cosmic neighborhood.

Three planets with masses ranging from 5.3 to 24.9 Earth masses were found orbiting the star 61 Virginis, which is 28 light years from Earth in the constellation of Virgo [Herald Sun]. That star can be seen with the naked eye under dark skies, and team member Chris Tinney says the system is strikingly like our own, noting that Neptune is only 17 Earth masses. In addition, NASA’s Spitzer Space Telescope recently found a ring of dust around 61 Virginis that’s about twice the distance from that star as Pluto is from our sun. The region between the newly discovered planets and that disk remains unexplored, the astronomers say, and could be the home of even more planets.

Further afield, the fourth planet discovered has a Jupiter-mass planet orbiting the Sun-like star 23 Librae, which lies in the constellation of Libra. It has a 14-year orbit compared to Jupiter’s 12-year orbit and is the second planet found around this star since 2006 [The Telegraph]. This star is about 84 light years away.

Tinney’s team found the new exoplanets by detecting the slight gravitational tugs they exert on their stars, and their proximity has him excited for what else might be in our vicinity, astronomically-speaking. “It looks like there may be many Sun-like stars nearby with planets of about that mass. They point the way to even smaller planets that could be rocky and suitable for life” [Herald Sun].

Fiber-Optic Link Brings Undersea Science Data Onto the Web | 80beats

Posted on by

wally-rover-webThe world’s largest network of fully wired undersea science stations has gone live off Canada’s western coast. The NEPTUNE network has begun streaming data from undersea instruments and sensors located on the Pacific Ocean floor directly to the Internet. The network is expected to produce 50 terabytes of data annually, all of which will inform scientists about everything from earthquake dynamics to the effects of climate change on the water column, and from deep-sea ecosystems to salmon migration [Scientific American].

NEPTUNE will also feature a deep sea rover nicknamed Wally that will measure the temperature, salinity, methane content, and sediment characteristics on the ocean floor. The $100 million project will produce more than pretty pictures and a fire hose of data—it can also provide advanced tsunami warnings that could save both lives and money.

The NEPTUNE network is already heralded as a revolutionary advancement for ocean explorers, a step toward wiring the oceans so researchers can remotely observe one of the last great unexplored areas on earth. Prior to NEPTUNE, communicating with a submersible required either a radio-equipped buoy or physically docking with the craft. Now, NEPTUNE lets a range of experiments, instruments, and undersea robots broadcast their data directly onto the web [Popular Science]. A fiber-optic cable loop, stretching 497 miles off the coast of Canada, links the undersea instruments to the Internet.

While the instruments will occasionally transmit images of the deep sea to the web, don’t expect a web cam on the seabed. Due to the sensitivity of deep-sea ecosystems to light, images from the remote-controlled NEPTUNE Rover are available only when researchers are moving the rover between locations. The lights will remain off most of the time and it’s unclear when they will be switched on next [Globe and Mail]. In the meantime, Scientific American has a slideshow of the project here.

Spandau Ballet To Be First Intergalactic Band Aboard Branson’s SpaceShipTwo Enterprise [Space]

Posted on by

Last week I invoked the wrath of trance fans everywhere by suggesting Above & Beyond, rumored to be the first musical act in space, should be kept up there. Turns out Richard Branson chose Spandau Ballet instead.

I think I now want a ticket aboard Enterprise even more than I did before.

They're performing just one song, rumored to be either Gold, True or I'll Fly For You (surprising news to anyone who thought they had just two songs) if Spandau Ballet guitarist/saxophonist Steve Norman is to be believed. With only six passengers and two pilots allowed on that first Enterprise flight, the five Spandau Balleters will make up almost half the human weight. Although judging by the looks of Tony Hadley these days, maybe it'd be more like 50/50. [The List]

Posted on by

For sysadmins with an ache for the open road, these Ford E350 4x4 vans, complete with telescoping 35-foot mast, are datacenters on wheels.

Eleven of the vans were built by EMI Technologies in the '90s for the National Telecommunications and Information Administration (NTIA) to monitor radio frequency interference. That's why in addition to the 35-foot antenna mast, each of the vans has a massive air conditioning unit inside, complete with in-wall duct work, as well as Onan 6.5K generators mounted inside a standard 19-inch server rack. A couple of them even have flip-down desks and rear-facing captain's chairs for pulling all-nighters.

EMI Technologies is still building similar vehicles for government agencies, but when I called them this morning they didn't have a whole lot to say about the vehicles. "How they were used might be classified," one man told me. But probably not—given the NTIA's purview, it's more likely these were used to make sure broadcast television stations weren't overstepping their spectrum or something.

What makes them a real deal are the vans themselves. Adam, the man who is selling the one with the lowest miles, said he'd probably let it go for around $16k. That's a fantastic deal for a dually van with the Quigley 4x4 conversion, even if it is over ten years old. I know this because I've been out pricing vans to convert into an ersatz Sportsmobile. I nearly wept when I saw these, because living in an impractical 4x4 van with an antenna mast tall enough to get a strong 3G signal on a remote mountaintop is my idea of heaven. I'm just not sure that there'd be enough living space inside for me and my dog next to the antenna pole and the 19-inch rack, even if I did remove the ridiculously large A/C unit. But love would find a way.

Here are the other two vans. If you buy one, let me drive it around someday!



Samsung ST5500 Point-and-Shoot Shows Off Wi-Fi and Nice Specs in FCC Appearance [Cameras]

Posted on by

Samsung's new camera showed up on the FCC website the other day, and the specs look pretty good so far: 14.2 megapixels, a 3.5-inch screen, and the ability to send photos via email and post online via Wi-Fi.

According to the FCC filing, the ST5500 also comes equipped with 100MB of memory, microSD support, and can take 1280x720 video at 30fps. It's also got 7x optical zoom and ISO settings up to ISO 3200, along with a max 1/2000 shutter speed. Expect it sometime early next year, and not for cheap.

Russian Scientists Field Test Geoengineering | The Intersection

Posted on by

I don’t know why this hasn’t (apparently) been reported before. But as I note today in Mother Jones:

Although so far it has received little or no attention, the journal Russian Meteorology and Hydrology recently published a new kind of geoengineering study whose lead author is the journal’s editor, the prominent Russian scientist Yuri A. Izrael. Known for his opposition to the Kyoto Protocol, his skepticism of human-caused global warming, and his enthusiasm for geoengineering, Izrael also happens to be a top scientific adviser to Vladimir Putin. And now, his paper reports on what is probably the very first geoengineering field trial. Israel and his team of scientists mounted aerosol generators on a helicopter and a car chassis, and proceeded to blast out particles at ground level and at heights of up to 200 meters. Then they attempted to measure just how much sunlight reaching the earth was reduced due to the aerosol plume.

The intervention was effective, the Russian scientists say. And in an accompanying article on geoengineering alternatives, Izrael and colleagues note that “Already in the near future, the technological possibilities of a full scale use of [aerosol-based geoengineering] will be studied.”

Up until now, scientists have largely studied the possibilities of geoengineering in relatively unthreatening computer models—not out in nature itself. They’ve just run a series of simulations to try to assess likely impacts. In this context, the apparent trajectory of Russian research sounds like something quite new. And it may prompt increasing calls for regulation of geoengineering interventions, even at the small scale research level where environmental consequences would be relatively minimal.

Note that this is a small scale field test; it is not like global climate is going to change because of this study. However, it does appear to break new ground, and moves us a step closer to actual interventions.

My report on all this is part of a much larger article on how failure at Copenhagen will give geoengineering advocates an even stronger hand than they are already obtaining. You can read the full report here.


What’s Basically the Most Adorable Children’s Gift I Can Imagine [Toys]

Posted on by

Here's the idea: your child scribbles an animal on Shidonni's website, they hand-sew a corresponding one-of-a-kind plush toy and mail it to you. Neat, right?

From the looks of this video, sweatshop laborers aren't stitching their fingers to your child's Christmas gift. Shidonni is just a small operation with a really good idea, actualizing a child's design into something they can hold.

I believe the cost is $85, and if you were interested in the gift for Christmas, you'd need to order by tomorrow, December 15th. No word on whether or not Shidonni will sew you one of the deadly tanks firing exploding ice cream cones that I drew as a kid. [Shiddoni]
