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.

Surgeries designed to relieve nerve-related pain occasionally result in new or persistent pain instead, and predicting which patients are at risk remains imprecise. Better prediction and prevention could improve surgical outcomes for chronic pain patients.

Despite recognition of its importance, reliable methods for mechanisms for ensuring that climate and development finance reaches women and marginalized groups are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
