Bionic Eye Attempts to Restore Vision

A bionic eye prototype developed by researchers in Australia aims to implant an array of electrodes in the eye that can deliver electrical impulses directly to neurons in the retina.

The group, called Bionic Vision Australia, has developed a device called the wide-view neurostimulator for patients suffering from degenerative vision loss.

“It is really designed to give people back their mobility so they can move around their environment and avoid obstacles,” says Anthony Burkitt, research director of Bionic Vision Australia. “We are also working on a second-generation product that will help people recognize faces and read large print.”

Apple's iPhone 4.0 software to deliver multitasking support

Apple this summer will go a long way towards silencing critics and catering to one of the most prevalent demands of its iPhone user base, when it introduces a multitasking solution through the handset's 4.0 software update that will finally allow several third party apps to run concurrently and in the background.

768-bit RSA cracked, 1024-bit safe (for now)

With the increasing computing power available to even casual users, the security-conscious have had to move on to increasingly robust encryption, lest they find their information vulnerable to brute-force attacks. The latest milestone to fall is 768-bit RSA; in a paper posted on a cryptography preprint server, academic researchers have now announced that they factored one of these keys in early December. Most modern cryptography relies on single large numbers that are the product of two primes. If you know the numbers, it's relatively easy to encrypt and decrypt data; if you don't, finding the numbers by brute force is a big computational challenge. But this challenge gets easier every year as processor speed and efficiency increase, making "secure" a bit of a moving target. The paper describes how the process was done with commodity hardware, albeit lots of it. Their first step involved sieving, or identifying appropriate integers; that took the equivalent of 1,500 y...
