Tech Today w/ Ken May

Existing methods for controlling brain activity tend to skew the results by their very nature — it’s difficult to behave normally with a wad of optical fibers or electrical wires in your head. The University of Illinois and Washington University have developed a much subtler approach to optogenetics that could lift that weight from the mind in a very literal sense. Their approach inserts an extra-thin ribbon into the brain with LEDs that are about as big as the neurons they target, stimulating deeper parts of the mind with high precision and minimal intrusion; test mice could act as if the ribbon weren’t there. The solution also lets researchers detach the wireless transceiver and power from the ribbon to lighten the load when experiments are over. Practical use of these tiny LEDs is still a long ways off, but it could lead to both gentler testing as well as better treatment for mental conditions that we don’t fully understand today.

University of Oxford chemists custom-built a 3D printer that fabricates “synthetic tissue,” or rather structures with tissue-like functions. Eventually, the technology could be used to crank out replacement tissue that could replace damaged human tissue or be used in new drug delivery systems. The material consist of a network of water droplets encapsulated in lipids, or fat molecules. “The droplets… form pathways through the network that mimic nerves and are able to transmit electrical signals from one side of a network to the other,” says Oxford University chemistry professor Hagan Bayley. Amazingly, the material can be chemically “programmed” to fold into various shapes as water is transferred around in the network.

Here at NAB, Intel just introduced the next generation of its Thunderbolt interface, which promises a data rate of 20 Gbps in both directions (on each of the two channels) as opposed to 10 Gbps for the previous version. Of course, the company stepped back for a moment first, boasting that Thunderbolt currently has about 200 licensees, and more compatible devices — along with new, thinner cables — should be coming out in the following months. Building up to the big reveal, Intel also shared some info about its new Thunderbolt host controller, (code-named Redwood Ridge), which will be built into some of Intel’s upcoming fourth-gen Core processors. But let’s talk about the real news: the next-gen Thunderbolt tech (code-named Falcon Ridge) enables 4K video file transfer and display simultaneously in addition to running at 20 Gbps. It will be backward-compatible with previous-gen Thunderbolt cables and connectors, and production is set to ramp up in 2014. An on-stage demo with fresh-off-the-press silicon showed the new Thunderbolt running 1,200 MBps, which is certainly a step up from what’s currently on the market. Update: We’ve added a video of the Thunderbolt demo from Intel’s stage. Hop on past the break to check it out. Filed under: Intel Comments

Today Facebook finally took the wraps off Home , a suite of apps and a home screen replacement for Android phones. It’s not just a new UI for launching apps however; it replaces the lockscreen with Cover Feed and prioritizes updates from people instead of apps. There is a standard paginated launcher, that is always just a swipe away. But the focus is on the full-screen images that are your new welcome screen. These are status updates from friends that you can easily flip through and double tap to like when someone posts something exciting. Plain text status updates are placed over a user’s cover photo, to keep the appearance consistent with photo-centric posts. Notifications are presented as small cards, which Facebook applies an algorithm to, in order determine the updates that are most important to you. Just like with the standard Android UI you simply swipe notifications off screen to dismiss them. But, if you want to remove all of them in one shot, you long press a single notification and the rest will be drawn to it and you’ll be able to dismiss the entire stack.

The FTC has managed to find two non-violent solutions to its Robocall Challenge , aimed at blocking auto-dialing telemarketers, thanks to winners Serdar Danis and Aaron Foss. The pair, who will receive $25,000 each, came up with variations on a system that would pre-screen calls before ringing your phone while allowing the FTC to blacklist known scammers at the same time. Google took a non-cash prize in a separate category with a scheme that would foil caller-ID spoofing often used by boiler rooms like the notorious “Rachel from card services” outfit, which has over a hundred numeric aliases. The FTC receives a whopping 200,000 complaints per month about the nuisance and screened nearly 800 submissions (see the More Coverage link), many of which show a certain, shall we say, passion for the topic. Check winner Foss’ video submission after the break. Filed under: Misc Comments Via: Huffington Post Source: FTC

Trying to create a large-scale, private cloud array can be a headache, since it often involves bringing disparate networking, server and storage systems together in one not-so-happy union. Wouldn’t it be nice to have a box that could do most of the hard work? Nebula thinks its newly launched Nebula One controller will do the trick. The rackmount device’s Cosmos OS quickly turns ordinary servers from the likes of Dell or HP into a unified cloud computer that centers on the more universal OpenStack platform, and which can also talk to Amazon Web Services . IT admins have a single interface to oversee the whole lot while skipping any outside help, and can scale up to a hefty 1,600 processor cores, 9.4TB of memory and 2.3PB of storage. You’ll have to ask Nebula directly about pricing, although we suspect it’s counting on the classic battle between time and money to clinch a deal — the weeks saved in setup and maintenance could represent the real discount.

Just in case you missed it last night buried in our interview with Epic Games VP Mark Rein , the company showed off a new real-time demo at GDC 2013 this week, titled “Infiltrator.” The nearly four-minute clip, showcases a sci-fi shootout created with its Unreal Engine 4 , and remarkably powered by a single GeForce GTX 680 . Now that we’ve piqued your curiosity a bit, check out this gorgeous display of futuristic espionage after the break, plus a bonus clip of the “Elemental” UE4 demo running on a PlayStation 4 dev kit in real-time.

Want to get a first-hand look at Microsoft’s updated OS ? You might be able to download the unreleased Windows Blue operating system on your own machine. Leaked build 9364 hit file sharing sites earlier today — according to Neowin , the 32-bit edition is available for download as a 2.63GB ISO, and likely hit the web from a Microsoft partner in France. Notable adjustments include larger and smaller Live Tiles, enabling a bit more Start screen customization, along with an updated side-by-side app view, which boosts multitasking efficiency by displaying two applications with matching width. Other additions include a Play option under the Devices panel, a screenshot button on the Share sidebar, and Internet Explorer 11, which comes packaged with the new OS. Windows Blue build 9364 appears to be an unauthorized leak, but even if you have any reservations about installing it on your own machine, you’ll surely be able to check out plenty of eye candy from other users over the hours and days to come. In the meantime, hit up the source links for a few more screenshots. [Thanks, Jim] Filed under: Software , Microsoft Comments Source: Winforum , Neowin

How many Roku models are there? Like, twelve? But it doesn’t matter: the newest one is here, and thankfully (predictably?) it’s the best one yet. So good that you’ll stop using other crap you own. So good you’ll use your cable box less. That good. More »

A company called Lumilor has announced a permanent electroluminescent paint that can be selectively illuminated by applying a charge to it. Burning Man attendees are already familiar with the ubiquitous, cheap EL wire, but this takes things to a new level: The LumiLor TM electroluminescent coating system is a patent-pending, practical, durable and affordable technology that can be illuminated with a simple electrical current. Used in conjunction with simple driver electronics, LumiLor will illuminate any surface brightly, and is capable of being custom-animated to flash in sequenced, strobed, and sound activated modes. The potential for customization is practically limitless! ABOUT LUMILOR ( via JWZ )
