Google employees yesterday let is spill thatbefore the end of 2012, you will be able to buy augmented-reality smart eyeglasses from the search giant. The Android-powered glasses will have an onboard camera that monitors in real time what you see as you walk (or, heavens preserve us, drive) down the street. The lenses will then overlay information about people, locations, and whatnot directly into your field of view.

The Audi A7 is the world's first fully Web-connected car. A built-in mobile data connection allows drivers to pull high-resolution 3D aerial images from Google Maps into the navigation screen, dispatching with current cartoonish maps. Using voice commands or controls on the center console, drivers can also search phone numbers, weather maps, real-time petrol prices from nearby stations, or Google "coffee shop" to look for a spot in the neighbourhood. For safety reasons, drivers can't pull up fantasy-football scores at a stoplight - but because the A7 generates a Wi-Fi signal, any passenger with a laptop can check them for you.

Traditionally, tracking diseases such as typhoid, and in particular working out where outbreaks begin, has been a little difficult to accomplish. In the case of fighting the disease in a country like Nepal, the problem is two-fold - not only is the rate of spread difficult to track, but because of the lack of a street address system, plotting cases visually has been almost impossible. Fortunately, this is about where Google Earth steps in.
