Google announced that they have updated their OneBox results, also known as quick answer results. This is to match the mobile and tablet designs Google released back in August. The new search results are cleaner, take up more space, but also are more interactive.
Moreover, according to an article published by Barry Schwartz at Search Engine Land, other results include unit conversion, holidays, sunrise times, weather results, time conversions and much more.
Google states that they are rolling this out to everyone using Google.com on their desktop over the next few weeks.
