Monkeys control virtual arm with their brains, may herald breakthrough for paraplegics

Monkey mind-controlled arm: It sounds like the name of an awesomely terrible sci-fi film or a fledgling grindcore group, but it's a very real phenomenon, and one that could pay significant dividends for paraplegics everywhere. Neurobiology professor Miguel Nicolelis and his team of researchers at Duke University recently devised a method by which monkeys (and, perhaps one day, humans) can control a virtual arm using only their brains. It's a concept similar to what DARPA has been pursuing with its mind-controlled "Luke" arm, with one important difference: Nicolelis' system not only allows users to remotely execute motor functions, but provides them with near-instantaneous sensory feedback, as well. Most similar techniques use electrode implants to stimulate brain activity, but this can create confusion when a patient's brain sends and receives signals to and from a prosthetic arm. Nicolelis circumvented this problem with a new interface that can read and transmit brain signals to an artificial limb, before switching to a receptive mode in just milliseconds.

After designing the technology, Nicolelis and his colleagues tested it on two, electrode-equipped rhesus monkeys. One set of electrodes was placed in the motor cortex of each animal, with the other implanted within their brains' sensory regions. They then trained the monkeys to look at a three identical objects on a computer screen and to "touch" each object with a virtual arm, controlled by signals sent from the brain electrodes. Only one of the three objects had a so-called "virtual texture," which, if selected with the on-screen arm, would send a sensory signal back to the monkey's brain (while triggering a tasty squirt of fruit juice for the lucky contestant). The two rhesus species ended up passing the test with flying colors, resulting in a "proof of principle" that Nicolelis' system can send tactile signals to the brain in almost real-time. The scientists have already developed a way for monkeys to control the arm wirelessly, and are now embedding their technology within a full-body, mind-controlled exoskeleton for paralyzed patients, as well. Of course, the technology still needs to be tested on actual humans, though Nicolelis seems confident that he and his team have already cleared the most difficult hurdle: "Since we cannot talk to the monkeys, I assume with human patients, it's going to be much easier."

Evernote Web gets a new interface, Facebook sharing, and more

evernote web
Evernote, the popular multi-platform 'digital memory' app, has done some serious re-tooling of its Web interface. In addition to a more polished UI that more closely mirrors the look of Evernote on the desktop, the update brings features like notebook stacks and snippet view to the Web.

Auto-saving is now enabled as well, and you can select multiple items by holding down the Cmd or Ctrl key on your Mac or Windows keyboard. If you've got items stored in your notebooks that you want to share with friends or co-workers, Evernote has improved that process, too. You can quickly post an item to Facebook, share it via email, or generate a Web sharing link to paste into an IM conversation or status update.

Head over to the Evernote Web login page to try out the new interface.

Tesla Model S test ride and factory tour (video)

Tesla Model S test ride and factory tour (video)
Tesla's been teasing us with the Model S electric car for what seems like a cruelly long time. But, we gadget fans need to remember that designing and releasing a car is a rather different prospect than something like a phone. If your new iDevice crashes you might lose your patience, but if your new car crashes, well, the results could be rather more disastrous.

Tesla is keeping up the teasing act with the Model S Beta launch, an opportunity for a lucky few to come and check out the company's factory (once the NUMMI facility in Fremont, CA) and to take a quick ride around the company's test track -- and we do mean quick. How do we know? Well, we got to come along. Join us for our impressions after the break.

Ad-supported Kindle 4 has built-in $30 "upgrade", gets rid of embedded special offers

Was it too cheap? Well, here's some great news for fourth-generation Kindle users already tiring of its embedded ads looking cheap alongside their Vertu phones. You can now pay Amazon the requisite fee and unsubscribe from built-in advertising and offers. Visit the Manage your Kindle webpage and you can edit your subscriptions for the newest entry-level e-reader. There seems to be no option, however, to do the reverse just yet. Would Amazon hand over $30 to push those special offers into our currently ad-free Kindle?

Google demands veto on OEM Android changes, stretches definition of 'open source'

Google, according to reports from "a dozen executives working at key companies in the Android ecosystem" is finally locking down the open source and easily-fragmented Android operating system.

As it currently stands, Google hands over the 'final' code for each version of Android, and OEMs and developers then spend some time customizing the OS to fit their hardware, and to create a unique and marketable flavor. That's all set to change, however.

Over the last few months, according to several people familiar with the matter, Android licensees such as HTC, Motorola and Facebook, have been asked to sign 'non-fragmentation clauses.' This new contract caveat will give Google the right to review and pass judgment on all changes to the Android OS. Two executives at Facebook say that they're unhappy that Google gets to review its changes to Android -- which is understandable, given Facebook and Google are direct competitors -- and there have also been allegations that Google is preventing some Verizon devices from shipping because they include Microsoft's Bing instead of Google search.

Google Cloud Print comes to HP ePrint printers

hp google cloud print
HP has become the first major OEM to deliver support for Google Cloud Print in retail-boxed printers. In an official release, HP announced that its ePrint-enabled printers are now fully Cloud Print compatible. Just sign in to your Google account, pick your HP ePrint device, and you're ready to fire off a print job from anywhere you've got Internet access. Well, as long as your app supports Cloud Print as well -- like Gmail and Google Docs, for example.

We're curious, though -- how many of you are still printing? Like our pals at Engadget, our printers have been mostly gathering dust for the last few years.

Kindle Touch 3G: A Step Up and a Step Down

Turns out there is a catch with the Kindle Touch 3G Amazon announced on Wednesday. The Touch 3G offers the addition of 3G wireless connectivity and sells for $149 -- $50 more than the Kindle Touch, which allows Web access over WiFi networks only. However, when you're using the 3G connectivity you can only access Amazon's Kindle Store and Wikipedia.
