This week on Tech Life, we're looking at the problems caused by illegal gold mining in Ghana. We'll hear how drones, AI and GPS trackers are being used to tackle the trade.

Also this week, Meta goes to court as it battles ads for so-called Nudifying apps. Is "I don't know" the solution to AI chatbot hallucinations ? And the pay-as-you-cook stove that's winning awards and improving health in Africa.
