Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Some children experience repeated seizures triggered by fever, and current prevention strategies remain limited mostly to managing fever itself rather than addressing the underlying seizure susceptibility. A more effective prevention approach remains needed.
