What about medical research ? And I'm not talking about RnD and finding new things, but just combing though the data. As far as I know there are tons of medical studies done every year. Too many for someone to comb through to find something which is common in multiple studies but hidden.
What if there is some hidden connection between let's say people who eat too many oranges and sit too much in the sun while smoking - and a certain disease ? Maybe no one did a study for that yet, but the data is there - indirectly.
The Ai can do it using the methods that AI already knows well, including statistical analysis, pattern recognition, and so on.
