Commercialization of carbon nanotubes is one of the holy grails of next-gen computing, and IBM thinks it’s made crucial steps toward making this a reality. This isn’t the first time that we’ve heard such a claim, of course, but IBM’s considerable resources will make this particularly interesting. The specific problem it’s been tackling is placing enough semiconducting nanotubes together to be useful in commercial chips, with current attempts being more in the hundreds, rather than billions that would be required. The new approach uses ion-exchange chemistry that allows controlled placement of nanotubes at two orders of magnitude greater than before, with a density of roughly a billion per square centimeter. To achieve this, the nanotubes are mixed with a soap-like substance that makes them water-soluble. Next, a substrate comprising two oxides and a hafnium oxide “trench” is immersed in the soap-solution, which results in the nanotubes attaching to the hafnium oxide canals with a chemical bond. Simple when you think about it! IBM hopes that as the materials and method are readily accessible now, that industry players will be able to experiment with nanotube technology at a much greater scale. Though, as we’ve become accustomed, there’s no solid timescales on when this might realistically unfold.

Neil Young Begins His Long Mission Towards True Audio Fidelity With Pono, A New Popular music Service And Device
Singer-songwriter-rocker Neil Young has been speaking about complications with modern audio codecs for decades. He was mad at CDs back in the 1990s and most recently he lashed out against MP3s and digital audio compression at a popular tech conference, saying “ My target is to try to rescue the art kind that I’ve been exercising for the past 50 years. We reside in the digital age and, sadly, it’s diminishing our popular music, not improving it … It’s not that digital is bad or inferior, it’s that the way it’s being used isn’t doing justice to the art. The MP3 just has 5 percent of the data present in the original recording. … The benefit of the digital age has required individuals to select between quality and convenience, however they shouldn’t have to make that selection.”
Luckily old Bernard Shakey understands a few people with some tech chops and is launching a service tentatively called Pono that will permit folks to switch, download, and play high quality songs on a user designed specifically for the service. He displayed his little player – a prismatic device that appears like a cross between a Shanzhai PMP and a box of Toberlone – on Letterman last evening and he ’ s aiming to offer 192kHz/24-bit audio files to purists who demand to hear every aural nook and cranny.
Young is working with labels to move the initial master tapes from each artist featuring a number of albums from Bob Dylan and additional greats. Young states the “ audio doesn ’ t get dummied down ” when played on the Pono.
While seemingly Quixotic, I think it ’ s lovely that Young is preserving this effort also in the face of an onset of reasonable bit-rate monstrosities. High quality new music has long been the provenance of the rich and/or aged and, although I suspect this will appeal even more to the older listener, a minimum of Young is dealing with one of the barricades to dulcet, high quality tracks.

A browser-based version of Skype now seems inevitable as Microsoft has taken the first steps towards its support of the web Real Time Communication (WebRTC) HTML5 standard. GigaOm reports that Microsoft submitted its own proposal for WebRTC today, as Customizable, Ubiquitous Real Time Communication over the Web (CU-RTC-Web). The standard, essential to a plugin-free video and audio communications in HTML5, will likely be used in future browser-based versions of Skype — something we’ve seen hinted at previously in Skype job listings.
Although Microsoft will implement a browser-based version of Skype video calling in its Outlook.com webmail client soon, we understand this particular implementation will require a plugin and will not use…

TI isn’t merely in the business of making ARM-based processors. The business makes all way of components and chips. Among the things in its vast arsenal of silicon are charging controllers. Texas Instruments’ latest providing, the UCC28700, not just draws an impressively reasonable sub-30mW when idle (meeting new five-star score requirements from the European Commission), however does so in a tiny bundle that does away with the need for an opto-feedback circuit or additional external elements. A second new controller, the TPS2511, deals with the problem of multiple chargers by moving to a 5V universal system for tablets and smartphones utilizing the USB Battery Charging 1.2 spec. This could suggest not just lower electrical power costs (if just nominally so), but smaller wall warts that can easily be utilized throughout various gadgets. For more, inspect out the PR after the break.

Don’t get too excited just yet, but PCIe 4.0 is coming. PCI-SIG, the body that governs the standard, has announced the next evolution of the interface, which should start popping up in servers, desktops, laptops and even tablets around 2015. Sadly, details are pretty slim on the slot — final specs aren’t expected to be announced before 2014. All we know is that PCIe 4.0 will be able to perform 16 gigatransfers per second (GT/s), which tells us only slightly more than jack squat. It simply means that a PCIe 4.0 card will be capable of transferring 16 billion discrete chunks of data per second, twice that of PCIe 3.0. What that doesn’t tell us though, is the size of those chunks. If they’re the same size, 4.0 will provide double the current bit rate of 1 GB/s per-lane. If, for some reason, the channel width were halved there would be no speed increase — but we seriously doubt that’s the case. So, will we be looking at 32 GB/s PCIe 4.0 x16 GPUs in a few years? That is a definite maybe.
Hey, look Engadgeteers! It’s another Kinect hack — except this one uses a real deal robot. Honda ushered ASIMO out to the crowds at IEEE’s 2011 International Conference on Intelligent Robots and Systems to show off its newly acquired pop and lock skills. Alright, so the silicon-gutted fella can’t krump with the best of’em yet, but he can probably do the locomotion — it all depends on your dance repertoire. After toiling away in their mad scientist lairs, the researchers behind the bot have managed to devise a means of mimicking human movement that translates mapped points on a user’s upper body into real-time, robot-replicated motion. The devious among you are likely imagining left-of-center uses for the tech, but let us deflate that mischievous balloon; there’ll be no instances of “stop hitting yourself ASIMO” here, as engineers have built-in collision and stability safeguards. The so-lifelike-it’s-Uncanny advancements don’t end there either, as ASIMO now also contains a database of text-inspired gestures — giving our future robot friend a means of physically expressing his cold, “I hate you so much right now” robo-tone. Other than finding himself at home in Italy, these innovations are sure to put ASIMO on the other end of our remote-controlled behest. Click on past the break to see this automated mime drop it like it’s hot.
Although the world is currently enamored of flash memory, today’s standard for solid-state storage, companies like IBM need to think a few years ahead. One of the technologies they’re looking at is called phase-change memory, in which a memory cell changes from a crystalline to amorphous phase, changing its resistance. Put a bunch of those together, and you’ve got yourself a binary storage system.
The trouble was that they couldn’t store more than one bit per cell, which means the tech couldn’t really scale. They’ve just figured that out, though: they assigned four discrete resistance levels (i.e. phase states) to represent “00,” “01,” “10,” and “11.” A clever and elegant solution that circumvents the problem completely. They also came up with a way of controlling for the fact that the resistance level tends to drift over time.
Interested? There’s much more to read over at IBM Zurich’s Research blog. You’re not going to be seeing this type of memory for a while, though; IBM puts “wide adoption” in 2016. We’ll update you then.
We knew Google was rather fond of its WebM video standard, but we never expected a move like this: the company says it will drop support for the rival H.264 codec in its HTML5 video tag, and is justifying the move in the name of open standards somehow. Considering that H.264 is presently one of (if not the) most widely supported format out there, it sounds a little like Google shooting itself in the foot with a .357 round — especially considering the MPEG-LA just made H.264 royalty-free as long as it’s freely distributed just a few months ago. If that’s the case, Chrome users will have to download a H.264 plug-in to play most web video that’s not bundled up in Flash… which isn’t exactly an open-source format itself. Or hey, perhaps everyone will magically switch to Chrome, video providers will kowtow, unicorns will gaily prance, and WebM will dominate from now on.
Just a quick note in case you’ve been gnawing your keyboard in anxiety: yes, people are still working on making OLED displays better. And bigger.
There have been scaling issues, but the big display companies have spent the last year or so fiddling around with the little tiny displays (and enormous ones) and as a result, have achieved some level of “know-how.”
They are going to use this “know-how” to create “real products,” presumably OLED TVs and displays. But will they be 3D?! Inquiring minds want to know!
