Scientists design a battery the size of your cornea, which runs off saline

We find out about tiny batteries, powered by your tears- and inspired by a Tom Cruise movie. And why chatbot detectors are detecting the wrong thing.

Associate Professor Lee Seok Woo, from NTU, in Singapore, tells us how a Tom Cruise film inspired him to create a battery, powered by tears, that's so small it could be fitted to a contact lens. Ben Derico reports from San Francisco on why Chatbot detectors are mistakenly accusing people for whom English is a second language of cheating in exams. Analyst Ben Wood, from CCS Insight, brings us up to speed on Apple's latest product plans.
