New Scientist report a new method of improving vision was patented. The idea is to amplify the light hitting the retina for vision impaired. Nanoscale specs of semiconductor = quantum dots are injected into the eye. They fluoresce when hit by photons and thus make light hitting retina cell brighter. Tests on rats shown that rats with quantum dot injected have more retina electrical activity. No words if improvement in the sight of the rats was actually observed.
Slashdot,, Engadget and others report research group in Kyoto succeed in reading 10×10 pixel images form visual cortex.
Being a neural net visual cortex encoding/hashing could be personal for each brain, but researchers seems were able to use the same response dataset to reconstruct images for two different people.
