Google's DeepMind has moved on from playing Go to more serious matters - attempting to solve some of the world's biggest health problems.
Projects include a tie-up with London Moorfields eye hospital, which will see it using one million eye scans to train its artificial intelligence system to diagnose potential sight issues, and development of an app to help doctors spot kidney disease.
Google's entry on to the healthcare scene has been welcomed by some, notably doctors who are desperate to apply some cutting-edge technology to antiquated NHS systems.
But less so by privacy groups and some patients, who have been surprised and concerned that their data - in some cases not anonymised - can be shared with the tech giant.
So what does Google want with our health data and should we be worried?
What's caused the row?
In May it was revealed that Google's DeepMind, had been given access to the healthcare data of up to 1.6 million patients from three hospitals run by London's Royal Free Trust in order to develop an app, called Streams, that would notify doctors should someone be at risk of developing acute kidney injury (AKI).
