Google Dictionary's OneBox has received an update to its UI and also added synonyms (were already available if you clicked "more info" to see the entire list of definitions). Another change is that the OneBox includes more definitions for each part of speech.
To trigger the Dictionary OneBox, search for [define word] or [word definition]. In some cases, Google shows the OneBox even if you don't include "define" or "definition". For example, if you search for [obnubilate], Google will show the definitions because it's likely that they're useful for many people.
Google Maps recently replaced the static icons for the satellite and street maps layers with interactive previews of the layers.
"When you're looking at a map in normal view, the satellite view button shows what the satellite view looks like on the little square where the button is and acts like a window to satellite view like you're looking through the regular map and it follows the map as it moves. I thought that was pretty cool."
