“Swallow a Capsule, Talk to Your Tummy!”

Imagine a tiny capsule you can swallow that talks to your tummy through an app! Scientists in China made one just like that. It can find bad bacteria that cause tummy problems and tell your phone. Then the phone can talk back to the capsule, and the capsule tells the good bacteria to fight the bad ones. It was tested in pigs, and one day, it might help humans feel better too. Science is making health smarter!
