Bionic eye closer to human trials with invention of implantable microchip

We've had our eye -- so to speak -- on Bionic Vision Australia (BVA) for sometime, and with the invention of a new implantable microchip it's coming ever closer to getting the bionic eye working on real-deal humans. The tiny chip measures five square millimeters and packs 98 electrodes that stimulate retinal cells to restore vision. Preliminary tests are already underway, and clinicians are in the process of screening human guinea pigs for sampling the implants -- the first full system is still on track for a 2013 debut. In the interest of future success: here's mud in your eye, BVA! Full PR after the break.

Major advance for bionic eye

UNSW researchers have unveiled the microchip which is expected to power Australia's first bionic eye.

Associate Professor Gregg Suaning, of the Graduate School of Biomedical Engineering and a project leader in the national bionic eye consortium, Bionic Vision Australia (BVA), said the new, 98-channel microchip, now undergoing preliminary lab testing, was a major step towards the goal of a functional bionic eye.

"This is a remarkable new microchip that has brought an Australian retinal implant much closer to reality," he said.

"At only five square millimetres, the device is tiny but represents a significant advance in nerve stimulation technology. The design team incorporated never-before attempted features with this design and they absolutely nailed every aspect. The result is mind boggling."

BVA Director, Professor Anthony Burkitt, said the production of the chip, a year after BVA received funding for the bionic eye project, represented "a major advance in technology".

"This microchip is at the heart of the retinal implant, which stimulates the retinal cells to elicit vision. It is an important component in the development of our first bionic vision system that may provide real, functional benefits for patients and make our technology competitive internationally," he said.

The microchip is performing well in preliminary lab testing. It will be at the core of the Wide-View neurostimulator device being developed by BVA, with the first full implant of the system in a patient planned for 2013.

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Google announces new ways to discover apps on Android Market, more tools for developers

Android Market may have a lot going for it, but most would surely agree that it could use some improvement when it comes to discovering apps that you aren't specifically looking for. Thankfully, it seems Google has indeed been aware of those concerns, and it's now announced five new features that should go so some way towards improving things. Those include some newly revamped top app charts that promise to be "fresher" and country specific, a brand new Editors' Choice section that highlights apps chosen by Google, a new Top Developers feature that places a special icon next to the name of developers that make the grade (currently more than 150), improved related apps on individual app pages and, last but not least, a new trending apps section that shows the apps growing fastest in terms of daily installs. What's more, while all of those features are currently exclusive to the web-based version, Google says they're also "coming soon" to the Andr...

LG adds 'Tweet-TV' enabled Android phone to its list of Mobile DTV prototypes

Whenever mobile digital television broadcasts finally take off LG will be ready and its latest concept design -- following the autostereoscopic 3D screen shown at CES -- is the Tweet-TV pictured above. At the National Association of Broadcasters show this week it's demonstrating the prototype Android phone with a Harris MDTV antenna that also pulls in relevant tweets and displays them over the broadcast being watched. Whether or not a dose of social networking will help MDTV succeed where others have failed remains to be seen but first we'll see if it manages to reach 40% of the US population later this year. The press release and a bigger picture follow after the break.
