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.

Mental health conditions often go undiagnosed simply because they're never screened for during regular medical visits, especially in areas with limited specialist access. Making mental health screening as routine as blood pressure checks remains an unmet global health goal.

Some people who die of sudden cardiac events had no known risk factors or warning signs beforehand, suggesting current screening methods miss a meaningful share of at-risk individuals. Better detection tools for this group remain an open need.

Lung cancer screening guidelines are generally built around smoking history, but a meaningful share of cases occur in people who never smoked at all and often go undetected until later stages. Better screening approaches for this group remain underdeveloped.
