Scientists have created an artificial retina implant that could restore vision to million

Scientists have developed a retinal implant that can restore lost vision in rats, and are planning to trial the procedure in humans later this year.

The implant, which converts light into an electrical signal that stimulates retinal neurons, could give hope to millions who experience retinal degeneration – including retinitis pigmentosa – in which photoreceptor cells in the eye begin to break down, leading to blindness.

The retina is located at the back of the eye, and is made up of millions of these light-sensitive photoreceptors. But mutations in any one of the 240 identified genes can lead to retinal degeneration, where these photoreceptor cells die off, even while the retinal neurons around them are unaffected.

Because the retinal nerves remain intact and functional, previous research has looked at treating retinitis pigmentosa with bionic eye devices that stimulate the neurons with lights, while other scientists have investigated using CRISPR gene editing to repair the mutations that cause blindness.

Now, a team led by the Italian Institute of Technology has developed a new approach, with a prosthesis implanted into the eye that serves as a working replacement for a damaged retina.

Artificial retinas made of this ultra-thin super material could help millions see again

IMG_8697

TRULY SUPER. There’s a reason researchers call graphene a “super material.” Even though it’s just a single layer of carbon atoms thick, it’s super strong, super flexible, and super light. It also conducts electricity, and is biodegradable. Now an international team of researchers has found a way to use the super material: to create artificial retinas.

16 futuristic predictions that came true in 2012

Nicknamed “Blade Runner,” South African sprinter Oscar Pistorius competed in the Olympic Games in 2012.

Just how futuristic did things become in 2012?  at the Olympic Games we watched a cyborg compete.  We marveled at the news that NASA was actually working on a faster-than-light warp drive. 2012 also featured the planet’s first superstorm, the development of an artificial retina — and primates who had their intelligence enhanced with a chip. Here are 16 predictions that came true in 2012.
