The so-called FingerReader, a prototype produced by a 3-D printer, fits like a ring on the user’s finger, equipped with a small camera that scans text. A synthesized voice reads words aloud, quickly translating books, restaurant menus and other needed materials for daily living, especially away from home or office.
The opposing view? Here:
The road to hell is paved with good intentions. Do the blind really want an audio reader? Most non-blind or hearing impaired do not understand the culture that lies in these communities, and are treated with a parental nurturing philosophy that borders on being totally insensitive to the needs of these communities. Did any one of these Samaritans ever ask the blind if they even want this. As far as I know most blind would prefer to read from a brail [sic] book, their second choice is an audio reader. When it comes to brail [sic] it is hard to create a page with a large array of dimples that would allow the blind freedom of reading (books, newsprint and leaflets). The visual impaired have a greater tactual sensitivity than all sighted people could never have, not understanding this aspect of their lives means not understanding the community you are trying to aid.
As far as computers is concerned, they have their own text to audio readers; which just needs to be switched on.

The study is an important technical feat in using reprogrammed cells [i.e., iPS cells], whose discovery in 2006 [in Japan] has unleashed huge interest, they said.
“We have basically created a miniature human retina in a dish that not only has the architectural organization of the retina but also has the ability to sense light,” said Valeria Canto-Soler of Johns Hopkins University School of Medicine, Baltimore.
“Is our lab retina capable of producing a visual signal that the brain can interpret into an image? Probably not, but this is a good start,” Canto-Solder said in a press release.

Cloudy eyes = cloudy corneas = corneal edema = dead endothelium
Yep, not fresh enough for people with more sensitive palate.
Fish covered with ice, not on ice, are rarely dehydrated. Those with sunken eyes probably smell too fishy already, they should be avoided indeed.

Google is developing smart contact lenses that measure the glucose levels in diabetics' tears.
Comment: All contact lenses have the potential of impeding corneal access to air/oxygen. This changes glucose metabolism big time. Also, the tear turnover rate may vary from individual to individual. Much remains to be done before this smart lens becomes practical.

It is this trigger mechanism that the team headed by Buchner and Weinkauf uncovered now. When a cell is exposed to stress, for instance when subjected to heat, phosphate groups are attached to a specific region of the protein. The negative charges of these phosphates break the links between the subunits and the large complexes consequently disintegrate into numerous smaller ones of only six or twelve subunits each. As a result of this breakup, the regions at the ends of the complexes become more flexible allowing the molecules to dock up with different partners, thereby preventing them from clumping – the protective protein is now active.
