MIT fit tens of thousands of artificial brain synapses on a single chip
MIT engineers put tens of thousands of artificial brain synapses on a single chip that's smaller than a piece of confetti.
Ford is 3D printing unique wheel nut locks based on driver voices
If you've got a set of sweet alloys on your car, you've likely got them protected with locking nuts which can only be loosened with a special key. But these aren't invulnerable to thieves, who are increasingly targeting car parts as vehicle security becomes more sophisticated. As such, Ford has come up with a novel way of using 3D printing to keep your alloys safe.
Titanium-gold alloy could lead to super-strong implants
Many bone implants (such as for hips and teeth) need to be replaced after a decade simply because they're not strong enough to survive for any longer. Rice University might put an end to those regular surgeries, though. Its researchers have crafted a titanium-gold alloy that's the strongest ever to be friendly to organic tissue -- four times stronger than pure titanium, and so strong that the team had trouble grinding it into a powder to check its purity. They created it by preparing titanium-3-gold (that is, three parts titanium for every one part of gold) at a high temperature, forming an extremely sturdy crystal structure.
A paperweight made from every 'collectible' element on Earth
Is your paperweight made of too few elements? Do you even have a paperweight? (No, not this.) We'd excuse you if you didn't, frankly. If you're in the market, though, the Element Cube is likely the one you want. As the name suggests, this is no vanilla flowers-in-glass affair. The maker claims it contains every "collectible" element on the planet (not the same as the 90-plus "natural" ones, many aren't available in practical quantities). That's 62 in total, distilled into an alloy.
Scientists learn to build better metals by freezing alloys in space
Metals are full of microscopic structures that define properties like strength, but it's hard to figure out how those structures work on Earth, where gravity skews their effects. An experiment aboard the International Space Station may have solved that dilemma, however. By freezing alloys in the station's extra-low gravity, scientists tracked the growth of microstructures in a pure environment and revealed a wealth of data about how metal forms. For example, the structures sometimes "breathe" (really, ripple) as they grow -- if you're not careful when producing metal, those tiny shapes will either break or disappear altogether.
The Big Picture: cooling molten metal in space
Ever wonder what hot metal would be like if it weren't bound by containers, liquids... or even gravity? You're looking at it. The European Space Agency has developed an electromagnetic levitator that the International Space Station is using to see how molten metal cools when it's free of the constraints you typically find on Earth. This experiment isn't intended solely as eye candy, of course. The station crew will use a high-speed camera to record the cooling process and make note of how it affects material structures. If the tests prove fruitful, they could teach people on the ground how to forge metal alloys with greater strength, exotic patterns and other traits that are very hard to produce using modern day techniques.
Doris Sung explains the tech behind her breathing, eco-friendly architecture (video)
Doris Sung has spent the past few years designing "breathing" architecture that adapts to environmental conditions. Thanks to an overview of her work at The Creators Project, we now have a simple explanation of how Sung creates these responsive structures. Her walls and windows are based on multi-layer metal "skins" that curl when certain layers react to heat -- the brighter the sun shines, the wider the skins open to let colder air through. Special software shapes each panel to maximize the cooling effect, even for very curvy surfaces. Sung's approach hasn't seen much real-world use so far, but she hopes for energy-efficient buildings that need very little air conditioning to remain comfortable.
Spotted at IDF: NEC's lightweight LaVie Z Ultrabook (hands-on video)
Remember NEC's LaVie Z Ultrabook we first heard about at Computex? It's a super light (875g / 1.93 lbs) and thin (15mm / 0.59-inch) magnesium alloy system running Windows 7 that's only available in Japan and we just spotted it here at IDF 2012 in San Francisco. Spec-wise you're looking at a 1.9GHz third-generation (Ivy Bridge) Core i7 CPU, 4GB RAM, 128GB SSD with integrated Intel HD 4000 GPU driving a 13.3-inch 1600 x 900-pixel display. It features an SD card slot on the left side, audio, USB 2.0, USB 3.0, HDMI and power connectors on the right edge along with the obligatory webcam. We spent a few minutes using the LaVie Z and were quite impressed with how lightweight and well made it is. It feels like a premium Ultrabook yet still looks unique -- unlike the plethora of me-too designs the PC industry's been dumping on the market lately (yes, we're looking at you, HP). The screen is nice and bright with decent viewing angles. NEC's done a good job with the button-less trackpad which is properly responsive. Sadly the keyboard is a bit of a mixed bag -- the short travel and small surface area of the individual keys will be an issue for some. Want to know more?

Apple and Liquidmetal hug it out, lengthen their pact until 2014
The deal between Apple and Liquidmetal was originally supposed to be a short-term fling. Technically, it expired in February this year, less than two years after the couple first met. There must have been a spark, as the two have just decided to extend their licensing deal through to February 2014. Of course, simply having a deal isn't the same as putting it to use, and there's no certainty that we'll see anything exotic materialize out of it: the last time Liquidmetal's extra-sturdy alloy was used in an Apple product, it wound up in a SIM card ejector tool. Still, Apple must have found something it wants to make in order to keep its union going forward, whether it's another tiny pack-in with an iPhone or (once costs allow) something a tad larger.
IBM develops 'instantaneous' memory, 100x faster than flash
You've got to hand it to IBM's engineers. They drag themselves into work after their company's 100th birthday party, pop a few Alka-Seltzers and then promptly announce yet another seismic invention. This time it's a new kind of phase change memory (PCM) that reads and writes 100 times faster than flash, stays reliable for millions of write-cycles (as opposed to just thousands with flash), and is cheap enough to be used in anything from enterprise-level servers all the way down to mobile phones. PCM is based on a special alloy that can be nudged into different physical states, or phases, by controlled bursts of electricity. In the past, the technology suffered from the tendency of one of the states to relax and increase its electrical resistance over time, leading to read errors. Another limitation was that each alloy cell could only store a single bit of data. But IBM employees burn through problems like these on their cigarette breaks: not only is their latest variant more reliable, it can also store four data bits per cell, which means we can expect a data storage "paradigm shift" within the next five years. Combine this with Intel's promised 50Gbps interconnect, which has a similar ETA, and data will start flowing faster than booze from an open bar on the boss's tab. There's more detailed science in the PR after the break, if you have a clear head.
New phase-changing alloy turns waste heat into green energy, exhibits spontaneous magnetism (video)
Looks like harvesting waste heat is all the rage in 2011. Yet another team of researchers -- this time at the University of Minnesota -- has found a way to harness energy from our hot castoffs. The group has apparently created a brand spanking new alloy that spontaneously creates energy when its temperature is raised by a small amount. Future uses for the material, known as Ni45Co5Mn40Sn10, include charging a hybrid car's battery with the help of waste heat from its exhaust. So what's the trick? Well, this wonder material is a phase changer, meaning it can go from non-magnetic to magnetic in moments, when the temperature rises. When that happens, the alloy absorbs heat, and bam! You've got electricity. The team is also collaborating with chemical engineers to create a thin film version of the material that could be used to convert waste heat from computers. If phase changing gets you all hot and bothered, check out a video demonstration of the alloy's sudden magnetism after the break.
Detroit DIYer cooks up stronger, lighter steel, shames scientists
You'd be forgiven for dismissing an amateur metallurgist if he claimed to have improved upon the presumably perfected technology of steel making. But Flash Bainite, the creation of Detroit entrepreneur Gary Cola, wowed a team of Ohio State University engineers by turning centuries of alloy processing on its head. Instead of heating the metal for hours or days, this well-equipped DIYer boosted the temperature -- quickly baking, then cooling sheets of steel that are 7-percent stronger than other forms and tougher than some titanium alloys. Flash Bainite is also more ductile than other steels, allowing it to crumple more before breaking -- perfect for absorbing impacts. Obviously this means stronger and lighter cars, laptops, and armored vehicles but, since the process takes all of about 10 seconds, it's also more energy efficient and cheaper than traditional steel making. Now, who has the number for the Nobel Prize committee?
Japanese researchers create palladium-like alloy using nanotechnology, 'present-day alchemy'
As you're no doubt aware, some of the precious metals used in consumer electronics -- like palladium -- can be both pricey and hard to come by, which has prompted some to harvest the materials from old electronics and reuse them, while others have been busily working on more readily available alternatives. Among that latter group are a team of researchers from Japan's Kyoto University, who have just announced that they've managed to create a palladium-like alloy using what's being described as "present-day alchemy." More specifically, they used nanotechnology to combine (and "nebulise") rhodium and silver, which don't ordinarily mix, into the new composite, which they say could eventually replace the real thing in a whole range of electronics and other products. Unfortunately, it's not clear when that might happen, but the researchers aren't just stopping at palladium -- they're apparently already looking at using a similar process to create other alloys.

Dell's Inspiron 15R Alloy Edition makes the wrong kind of waves
An "Alloy Edition" laptop sounds like something that should look pretty decent, right? Well, ideas and execution are two entirely different things, as evidenced by Dell's new Inspiron 15R Alloy Edition. While the alloy part of the equation isn't bad, it's unfortunately only available in a "waves" pattern that we can only hope looks better in person. As for the laptop's specs, you can expect the usual choice of Core i3, i5 or i7 processors, a 15.6-inch 1,366 x 768 display, integrated Intel graphics or an optional ATI Mobility Radeon HD 5650, up to 8GB of RAM, and up to a 750GB hard drive. Somewhat curiously, while the laptop is up on Dell's site with a "customize" button, it isn't yet actually available to customize, and there isn't a starting price or release date to be found.

Apple snags Liquidmetal IP, may just revive the eMac with an amorphous metal chassis
Ah, who are we kidding -- we're guessing a true, bona fide headless iMac would hit the market before the eMac ever makes a triumphant return, but it's surely a novel thought, no? In a recent 8-K filing with the SEC, Apple made public that it had essentially acquired "substantially all of [Liquidmetal's] intellectual property assets," not to mention a "perpetual, worldwide, fully-paid, exclusive license to commercialize such intellectual property in the field of consumer electronic products in exchange for a license fee." In other words, Apple just bought up the rights to integrate Liquidmetal's amorphous metal alloys into its product line, which would allow the company to create metallic wares without sweating the typical structural or strength limitations found in conventional metals. There's no mention of dollars exchanged here, nor any details on what exactly Apple plans to do with its newfound IP (shown after the break), but we're guessing the procurement team didn't sign the dotted line for kicks and giggles.
Synaptics Fuse concept handset puts a new squeeze on touchphone interaction
In case you weren't aware, Synaptics dabbled in the touchscreen handset game way back in 2006 with the Onyx concept, before phones like the LG Prada and Apple's iPhone came along and proved the idea so convincingly. However, Synaptics thinks innovation has stagnated since, and has girded itself once again to attempt another trend-setting concept. This one's a bit more wild: the "Fuse" involves contributions from Alloy, TAT, Immersion and Texas Instruments, and includes squeeze, tilt and haptic interaction. The big idea is to approach single-handed and no-look operation on a touchscreen handset, no small feat to be sure. The result is a pure kitchen sink of sensors, including a touchpad on the back of the phone, touch and pressure sensitive strips along both sides of the phones, dual haptic feedback motors, a 3-axis accelerometer and of course a new-generation Synaptics touchscreen in front. The TI OMAP 3630 processor powers the TAT Cascades 3D UI Engine which attempts to contextualize UI interaction with perspective tilts and fancy motion, and the haptics feeds back to let you know where your finger is on the screen -- an attempt to emulate feeling out the correct nub for keypad orientation on a button phone. We'll have to play with it to find out if Synaptics is really on to something, but even if the Fuse isn't the next best thing, we could certainly see somebody using some of these sensors to improve existing handset interaction. Check out a quick video after the break.
NC State intellects design twistable, shape-shifting antennas
NC State may be well on its way to yet another underwhelming season on the hardwood, but it seems as if a few of its most spirited boffins aren't even taking any time off to celebrate the season-ending victory over the hated Heels on the team's final football game. Dr. Michael Dickey and team have just published their latest invention, and if this thing ever reaches commercial status, you can expect ordinary objects to become a lot more intelligent. The crew's shape-shifting, twistable antenna overcomes the common limitation of copper-based alternatives by relying on an alloy that can be "bent, stretched, cut and twisted" while still transmitting or receiving a signal. Aside from enabling concept phones like the Ondo to become real, the development could also allow for stretchable antennas to be integrated into actual structures, giving buildings and bridges a way to communicate stresses to architects. Too bad it can't communicate the crumbling of an athletics program to an oblivious AD, but hey, there's always room for improvement in version 2.0.
Sears uses virtual worlds for back-to-school marketing strategy
Summer vacation is setting fast. Soon school classrooms will fill back up with eager students looking to display their latest duds and focus on buffing their intelligence. Shopping has to ensue before that big first day back, and Sears and coolness don't go together nor is it the likely first shopping choice. That's not preventing their marketing department from attempting to target teens in the back-to-school spending craze. Sears has a new strategy which is to promote their products and brand name through social networks and virtual worlds frequently inhabited by teens and kids. The new virtual Sears fronts are endless arriving all across the Metaverse. A fashion event will he held in the Sears virtual store in Zwinky's Zwinchester Mall. 3d avatar creator Meez also has Sears B-T-S boutique offering clothing, backgrounds, and animations. Additional promotions will run across Alloy. The Gofish network will be hosting a runway contest in the Cartoon Doll Emporium and also at WeeWorld. Another Sears shop is present in Poptropica and The-N.com. NeoPets has some virtual Sears's goodies in their summer faire event. If that wears you out, Sears wants everyone to lounge around. It's commercial fun for the whole family, well not this blogger. Nonetheless, it's still interesting to see the searing crossover.[Via Virtual World News]
