Corneas regrown using human stem cells

By - July 4, 2014 2 Pictures
Medical researchers working with human stem cells have discovered a way to improve regrowth of corneal tissue in the human eye. Using a molecule known as ABCB5 to act as an identifying marker for rare limbal stem cells, the researchers were able to use antibodies to detect ABCB5 on stem cells in tissue from donated human eyes and use them to regrow anatomically correct, fully functional human corneas in mice.

Nissan takes the wraps off Concept 2020 Vision Gran Turismo

By - June 16, 2014 3 Pictures
“Cor, I’d like to take that for a spin.” It's what most of us think when looking at concept cars, but the chances of that ever happening are usually less than slim. The Nissan Concept 2020 Vision Gran Turismo is an exception to the rule – at least, it's a virtual exception. That’s because next month, the just revealed supercar concept becomes available for download for Polyphony Digital’s Gran Turismo 6 video game for the Playstation console. Read More

Praying mantises outfitted with tiny 3D glasses

By - April 29, 2014 8 Pictures
Although us humans take 3D vision for granted, it's not a standard feature throughout the animal kingdom. In fact, praying mantises are the only invertebrates known to possess it – a fact which makes them excellent hunters. Scientists at Britain's Newcastle University are now studying the insects' ability to see in 3D, to determine if it could be copied in human technologies such as robot vision systems. As part of that study, they're equipping mantises with the smallest pairs of 3D glasses ever made. Read More

Portable scanner designed to make eye exams quicker and easier

By - December 23, 2013 2 Pictures
If you're like a lot of people, you don't make an annual trip to the ophthalmologist to get your eyes checked ... and you really ought to, in order to catch any problems before it's too late. If it were possible to get them checked at a regular doctor's office or clinic, though, perhaps you might do so more often. That's one of the reasons that a team at MIT have designed a new hand-held retinal scanner, that can quickly and easily be used anywhere. Read More

Scientists run eye cells through an inkjet printer

By - December 19, 2013 1 Picture
Imagine if conditions that presently cause blindness could be treated by simply by fabricating new tissue, and using it to replace the defective part of the retina. We may not be at that point yet, but we've definitely taken a step closer, thanks to research being conducted at the University of Cambridge. Scientists there have successfully used an inkjet printer to "print" rats' retinal cells onto a substrate, paving the way for the creation of custom-made eye-repair material. Read More

Telescopic contact lens with switchable magnification to help AMD patients

By - July 1, 2013 8 Pictures
Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the western world. Unfortunately, conventional optical aids provide little help for a retina which has lost the acuity of its central area. Now a team of multinational researchers led by University of California, San Diego (UCSD) Professor Joseph Ford has created a telescopic contact lens that can switch between normal and magnified vision to offer AMD patients a relatively unobtrusive way to enhance their vision.

Researchers transmit braille directly to the retina of blind test subject

By - November 23, 2012 1 Picture
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
