The update has seen new instructions passed on to its team of human reviewers - made up of more than 10,000 people - so they can give feedback to train the algorithm which actually delivers search rankings.
Google explained: "While we typically show the latest and most comprehensive version of a story in news results, we've made changes to our products globally to highlight articles that we identify as significant original reporting.
"Such articles may stay in a highly visible position longer. This prominence allows users to view the original reporting while also looking at more recent articles alongside it.
"There is no absolute definition of original reporting, nor is there an absolute standard for establishing how original a given article is.
"It can mean different things to different newsrooms and publishers at different times, so our efforts will constantly evolve as we work to understand the life cycle of a story."
