Naver Webtoon has launched an AI-based interactive service that lets readers create stories using the company’s webtoon intellectual property. The service, called byUs, allows users to talk with characters based on creator-approved webtoon IP to develop new narratives. It offers two formats: original stories built on the source world and character settings, and fan stories that add new situations and relationships. Features include suggested replies, autoplay, snapshots and special cuts.

Eli Lilly\'s next-generation obesity treatment retatrutide may reduce fatigue, a side effect often associated with GLP-1 drugs, by regulating energy metabolism as well as suppressing appetite.
