Bloomberg -- "Blind mice had their vision restored with a device that helped diseased retinas send signals to the brain, according to a study that may lead to new prosthetic technology for millions of sight-impaired people. The technology moves prosthetics beyond bright light and high-contrast recognition and may be adopted for human use within a year or two, said Sheila Nirenberg, a neuroscientist at Weill Cornell Medical College in New York and the study’s lead author.
“What this shows is that we have the essential ingredients to make a very effective prosthetic,” Nirenberg said. Researchers haven’t yet tested the approach on humans, though have assembled the code for monkeys.
Nirenberg and co-author Chethan Pandarinath first monitored healthy eyes to determine the set of equations that translate light received by the retina into something the brain can understand. Then, they used special glasses to create a similar code and deliver it to the eye, which they had injected with a virus containing light-sensitive cells. The cells received the code and fired electric impulses, which the brain could interpret as images.
Nirenberg’s research “is basically giving vision back to a system that doesn’t work,” said Aude Oliva, a principal investigator at the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory, who wasn’t involved in the research. “I’ve never seen, and other people have never seen, this quality.”
No foreseeable barriers should stop the movement into humans now that the technology has been created, Oliva said. Nirenberg said that if researchers can come up with adequate cash to fund clinical trials, she hopes to soon adapt the technology."
MP: In the midst of all of the gloom and doom we hear about daily, the pending fiscal cliff, talk of a double-dip recession, The Great Stagnation, etc. we still hear inspiring stories like this on a regular basis, a confirmation that technology, innovation and ingenuity march on, and deliver advances that make the future ever-brighter all the time. It's a demonstration that our "ultimate resource" - America's human resources, human capital and entrepreneurial talent - are still strong, and the vitality and dynamism of the U.S. economy will prevail. The U.S. economy has experienced 33 recessions since around the time of the Civil War, and has successfully emerged after each one into a new cycle of growth and expansion, and there's no reason that this last recession and the current expansion will be any different.
As one example, when we look back on the period of U.S. history from 1870-1900, nobody describes that period as one of seven severe economic recessions, or a period when the U.S. economy was in recession 179 months out of 336 months, or more than half of that time period. Instead, when we reflect on that period today, we think of the many amazing, game-changing inventions that emerged during that era despite the tough economic conditions, including the typewriter, air brakes, tungsten steel, barbed wire, telephone, internal combustion engine, phonograph, moving pictures, a longer-lasting light bulb, player piano, machine gun, gas-engine motorcycle, radar, gramaphone, contact lenses, escalator, zipper, bicycle frame, vacuum cleaner, zeppelin and the radio. Likewise, a hundred years from now people will look back on this period of history more for its innovations (3D printing, iPhone, iPad, robotics, nanotechnology, advanced drilling technologies for oil and gas, and prosthetic technology for millions of sight-impaired people, etc.) than for the fact that we went through the Great Recession, which in comparison was relatively mild compared to the severe, recessionary conditions of the 1870-1900 period that included a five-year and a three-year recession.
