Google throws a lot of services at the wall, and unfortunately, Google Health never stuck. However, Mountain View is now taking another crack at the subject through its Knowledge Graph. To remind you, that's basically a box of info and images that appear when you search for historical events, figures or objects. For example, typing in "Leonardo Da Vinci" brings up a quick bio and images of the Renaissance man, while entering "Mona Lisa" shows a card on his best-known oeuvre. The same will now work on various diseases: for instance, "cold symptoms" brings up a card showing "nasal congestion, nasal pain and irritation and sneezing" and steers you toward the National Health Service for more info in the UK .
