The memory standards committee known as the JEDEC Solid State Technology Association announced the publication of JEDEC DDR3L, which the association says will enable a significant reduction in power consumption for a boatload of products that utilize memory, including laptops, desktops, servers, networking systems, and a a range of digital devices.
Those of you donning your detective caps might have guessed that the "L" in DDR3L stands for "Low Voltage," and you'd be right. Devices that adhere to the new standard will operate from a single 1.35V power supply voltage compared to 1.5V in existing devices, JEDEC said.
DDR3L-based memory devices will consume 15 percent less power compared to standard DDR3 (sometimes more), and a whopping 40 percent less than standard DDR2, all without taking a performance hit. The upshot here is longer battery life and cooling running devices.
While we sit and wait for downloadable and streaming content to fully replace optical media, Sony, with the help of some talented folk at Tohoku University, is already working on the next iteration of Blu-ray. Those involved say that by harnessing a blue-violet laser, a disc could come crammed with up to 50 full-length movies or an entire TV series.
"This latest successful development is an all-semiconductor laser picosecond pulse source with a laser wavelength of 405 nanometers (1nm = one billionth of a meter) in the blue-violet region," Sony explains. "It is capable of generating optical pulses in the ultra-fast duration of 3 picoseconds (1 picosecond = one-trillionth of a second), with ultra-high output peak power of 100 watts and repetition frequency of 1GHz."
We love it when companies talk all geeky to us, and there's plenty of nerd-speak in the full press release. Put into plain English, this latest blue-violet laser is more than a hundred times stronger than the world's highest output value for conventional blue-violet, and barring any setbacks, will succeed the current Blu-ray format in the coming years.
One way to tell the world to "Kick my ass and mug me" is to simply wear a custom shirt emblazoned with that very plea. Or you can walk around dark alleys and other areas you have no place being toting your $600 iPad front and center in your Syte Shirt's pouch. Of course, the startup's designers have an entirely different pitch, which goes a little something like this:
"Syte Shirt manufacturers an interactive shirt that lets you safely carry the iPad hands-free on your chest while allowing you and others to fully interact with the iPad through a transparent window," Syte Shirt's marketing team writes. "Not only is it an accessory, the shirt is also a fashion statement for those that want to show off cool designs, photos, movies, or animations while trotting around town. It's the first shirt that has a constantly changing design!"
Syte Shirt lists several examples of how you can use your new clothing accessory, including playing movies or firing up interactive games for your kids while keeping your hands free, or broadcast a football game while enjoying a tailgate party. Seriously.
"The possibilities of this product are only limited by the imagination of its users, and I really think we're going to be amazed by the ideas our customers come up with for this great product," Syte Shirt founder Joseph A. Young writes.
Samsung on Monday claimed an industry first by announcing it has begun mass producing 2Gb (gigabit, not gigabyte) Green DDR3 using a 30nm manufacturing process.
"We’re seeing a sharp rise in demand for DDR3 chips and are meeting that need with the timely introduction of 30nm-class Green DDR3 solutions," said Soo-In Cho, president, Memory Division, Semiconductor Business, Samsung Electronics. "Thirty nano-class DDR3 DRAM will deliver the most satisfying user experience possible, offering extremely high performance and reduced power consumption for PC and server applications designed to capitalize on new multi-core processors."
According to Samsung, these environmentally sound memory modules are capable of reaching up to 1.866Gbps at 1.35V, while PC modules can ramp up to 2.133Gbps at 1.5V. That's 3.5 times faster than DDR2 and 1.6 times faster than 50nm DDR3, Samsung says.
So how does this translate into the real world? According to Samsung, 30nm-class 4GB DDR3 kits for PCs can operating up to 60 percent faster than two 50nm-class 2GB DDR3 solutions, all while using 65 percent less power.
IBM on Thursday said its going to throw millions -- as in, $100 million -- into a new research initiative that will have IBM collaborating with clinicians to develop new technologies, scientific advancements, and businesses processes for healthcare and insurance providers.
"Improving the quality of healthcare requires more than just digitizing health data," said Chalapathy Neti, Global Lead, Healthcare Transformation at IBM Research. "In fact the proliferation of diagnostics technology has in many ways added another layer of complexity, making it more difficult to gain valuable insights for patient care. Enabling greater coordination between care providers and transforming data into clinical decision intelligence could improve patient outcomes and help lower costs of healthcare today."
The money will be doled out over the next three years with a focus on three main areas. These will include evidence generation, streamlining the healthcare delivery process to improve service quality, and new incentives and models to reward patient outcomes rather than only treatment and volume of care.
It's been said that the eyes are the windows to your soul, but for psychologists John Kircher, Doug Hacker, Anne Cook, Dan Woltz, and David Raskin, your eyes also serve as a pair of honest Abes unable to tell a lie. Straight to the point, the aforementioned research team, who hail from the University of Utah, have come up with an eye-tracking technology that could replace the polygraph for lie detection.
"The eye-tracking method for detecting lies has great potential," says Gerald Sanders, a venture capitalist who manages Credibility Assessment Technologies (CAT), which licensed the technology. "It's a matter of national security that our government agencies have the best and most advanced methods for detecting truth from fiction, and we believe we are addressing that need by licensing the extraordinary research done at the University of Utah."
The nuts and bolts of it all is this. Rather than rely on a person's emotional reaction to lying, like a typical polygraph test, eye-tracking technology measures the subject's cognitive reaction. The test begins with a series of truth and false questions on a computer while different measurements are taken, including pupil dilation, response time, reading and rereading time, and errors.
According to the researchers, a subject who isn't being honest tends to work harder. They may have dilated pupils and take longer to read and answer questions, all of which are indicative of a dishonest answer.
"We have gotten great results from our experiments," says Kircher. "They are as good as or better than the polygraph, and we are still in the early stages of this innovative new method to determine if someone is trying to deceive you."
Think you've gone green because you put your PC to sleep during coffee breaks? Try building a solar airplane capable of staying in flight for 24-hours, including night time.
Impossible? Pshaw! The Solar Impulse HB-SIA proved otherwise, which took off from a base in Switzerland at precisely 6:51 a.m. Wednesday and stayed in the air for 24 hours powered only by the solar energy it managed to corral during the daytime hours.
"24 hours and a successful flight through the night!," the Solar Impulse team posted on their Twitter account. "This is a milestone in putting fossil fuels behind us."
This particular milestone was seven years in the making, starting when a team of 70 designers, engineers, and other incredibly smart folk collaborated to create the first prototype of what would later become the Solar Impulse HB-SIA. And had it not been for a glitch with the telemetry transmitter, the feat would have been achieved a week ago.
"Goal achieved for SI. Historic moment. Jubilation here in Payeme, Switzerland!," read another tweet.
So here's the deal - a research team headed up by Washington State chemistry professor Choong-Shik Yoo has come up with a battery design capable of condensing energy like nobody's business.
We won't pretend we fully understand what the flip is going on, but in a nutshell, the battery consists of material called xenon difluoride (XeF2), which is a white crystal mostly used to etch silicon conductors. The material is placed into two diamond anvils, where it's then pressurized. And therein lies the key - in normal circumstances, molecules in XeF2 don't come close to each other. But as they're squeezed together -- the pressure from the anvils is roughly equivalent to what you'd find halfway to the center of the Earth -- the molecules go on to form 3D metallic "network structures," pushing the mechanical energy of the compression process to be stored as chemical energy within the molecular bonds.
Yeah, we don't really follow it either, but according to Choong-Shik Yoo, this "is the most condensed form of energy storage outside of nuclear energy." Now that we can wrap our craniums around.
Where this all leads remains to be seen, but it could see use in superconductors, super-oxidizing materials, and other super applications. Sounds super to us.
Did your car really need new muffler bearings and was it actually low on blinker fluid, or did your mechanic take you for a ride? You may never know (we do - he took you for a ride). To help put your mind at ease (and maybe to get back at its staff for joining a union), Audi is test driving a new program called Audi Cam.
The way it works is when you drop off your Audi for repair, you end up tethered to your mechanic with a two-way radio and headset video camera. You're then whisked away to the waiting room, where you can watch your mechanic's every move and, for better or worse, communicate with him as he works, and vice versa.
Snarkiness aside, we can see where this would be useful, both for the mechanic and the customer. We can also see where it would be incredibly annoying, at least for the repair guy. Either way, Audi Cam so far is only available in Europe.
Origami is one of those things where it seems you either have a knack for it or you don't. If you don't, all the practice in the world won't help turn your crumpled creations into works of art, but maybe one day your PC will be able to lend a helping hand.
If so, you can thank Robert Wood of Harvard University and Daniella Rus and Eric Demaine at the Massachusetts Institute of Technology. The trio have developed a material that's able to fold on its own. It's a square sheet of glass fiber 4cm wide and patterned with 32 triangular tiles, the seams of which are made from flexible silicon rubber and a "shape memory" alloy foil, New Scientist reports.
To make it all work, each foil was folded in two and held in a vice and then heated to 420C for 30 minutes. This allowed the foil to retain a memory of its fold when opened back up and allowed to cool.
After this was done, the research team fired up origami simulator software to calculate the sequence of folds required to put together two basic objects, one being a paper airplane and the other a boat. A current was then sent through the foils heating them above their "transition" temperature of 70C and forcing them to fold.
