Researchers at Stanford University are designing a new device that could help people with degenerative eye diseases restore their vision — by implanting a photovoltaic silicon chip beneath their retinas.

With degenerative eye diseases, the retina’s light-sensing cells die off, though the rest of the eye remains healthy.

Google has already brought a pile of new fonts and templates to Google Docs this month, and it's now back with another fairly big new feature. Open a document today and you'll find a new Research tool on the side of your page (which can be toggled on and off), offering the ability to search for any topic and get results without having to leave the document you're working on. Those results can include images, quotes and other basic information that's delivered right in the sidebar -- and, of course, the usual search results that you can open in a new tab or window if you want to dive deeper on a subject. Hit the source link below for all the details on how to use the new tool, or simply fire up a new document to try it out for yourself.
