Today Apple upgraded the offerings in its MacBook Pro with Retina display line

Apple today pushed out a refresh of its MacBook Pro with Retina display lineup, giving both the 13- and 15-inch models a little more horsepower under the hood. Additionally, Apple has dropped the price of the top-of-the-line 15-in version of its high-resolution notebook, perhaps making that high-end upgrade a little easier to justify.  Read More

The eye is often compared to a camera, but although its basic design is as simple as an old-fashioned box Brownie, its detailed structure is more complex than the most advanced electronics. This means that, unlike simpler organs, studies of retinal disease rely heavily on animal studies, and treating such illnesses is extremely difficult. One ray of hope in the field comes from researchers at Johns Hopkins, who have constructed a functioning segment of a human retina out of stem cells that is able to respond to light.  Read More

The Mobile Authentication via Retina Scanner (MARS) prototype is compact and portable (Pho...

Retinal scans have a lot going for them as a form of identification. You can’t forget your retinas, they're unique, they’re a lot harder to steal than passwords, and Captain Kirk uses them. The problem is, the technology needed to run a reliable retinal scan is often bulky, expensive, and hard to use. Scientists at the Dresden-based Fraunhofer Institute for Photonic Microsystems (IPMS) have shrunk down retinal scanning technology in the hopes of making retinal scans a more widespread identification technology.  Read More

The second iPad Mini gets its first 'Retina Display'

As expected, Apple unveiled a new iPad Mini with an improved display upgraded to "retina" status, and a complement of new colored covers and cases for both the smaller slate and the new iPad Air.  Read More

We take a look at how Toshiba's KIRAbook and Apple's 13-inch MacBook Pro with Retina displ...

Last week, Toshiba entered the ultra high-end laptop market with the KIRAbook, a thin and light Ultrabook with a number of compelling features. The laptop is the first Windows 8 device to feature a Retina-level display (or PixelPure as Toshiba calls it), throwing it into direct competition with Apple's MacBook Pro with Retina display. We take a look at both devices to see which (if either) comes out on top.  Read More

The basic components of the Argus II Retinal Prosthesis, used in the experiment

Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina.  Read More

Researchers have reportedly restored near-normal vision to blind mice, using a prosthesis ...

Retinal prostheses such as the Argus II, Bio-Retina and the Retina Implant AG microchip all work – more or less – by stimulating the retina’s ganglion cells with light-induced electrical signals. The images produced in the patient’s visual cortex tend to be quite rudimentary, however. This is partially because the rate at which the signals are sent isn’t the same as the rate of neural impulses normally produced by a retina. Now, researchers have deciphered the neural code used by mouse ganglion cells, and used it to create a prosthesis that reportedly restores normal vision to blind mice. They have additionally deciphered the neural code of monkeys, which is close to that used by humans, so a device for use by blind people could also be on the way.  Read More

Retinal implant with power cable (Image: Retinal Implant AG)

Retinitis pigmentosa (RP) is a degenerative eye disease that affects 200,000 people in the United States and Europe and has left 15 million people permanently blind worldwide. German biotechnology firm Retina Implant AG has developed a microchip that provides a useful degree of artificial vision in patients who have been blind for even long periods. The 3 x 3 mm (0.118 in) chip is implanted below the surface of the retina where it electrically stimulates the optical tissues. After successful clinical trials in Germany, the chip is now being tested in Hong Kong and Britain before moving on to planned trials in the U.S.  Read More

At least 25-30 million people worldwide have age-related macular degeneration (AMD), one of the leading causes of blindness in middle-aged and older adults. The Israeli start-up Nano Retina has announced their new Bio-Retina, a tiny array of photodetectors which can be implanted directly on the retinal surface. Ready to enter clinical trials in 2013, the Bio-Retina restores vision to AMD sufferers almost immediately following the simple implantation process.  Read More

LG's five-inch LCD display can handle full 1080p HD video

LG has introduced an impressive new smartphone display that's expected to come to new handsets in the second half of 2012. The panel is five inches across, and features a pixel density of 440ppi with an aspect ratio of 16:9, capable of displaying 1080p HD content. This impressive new display trumps Apple's retina display, as well as the larger screens on phones like the Galaxy Note in terms of size versus pixel density.  Read More
