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.

Concrete and asphalt trap heat, turning cities into dangerous hot zones during extreme weather, especially for people without air conditioning. Redesigning cities to stay cooler is now a matter of public safety, not comfort.

Neuroscience can map which brain regions activate during thought, but nobody can explain why that activity produces subjective experience at all. This gap separates our understanding of the brain from any real understanding of the mind.

Dark matter and dark energy make up roughly ninety five percent of the universe, yet we've never directly detected either. Everything we can see and touch is a small fraction of what's really out there.

Current approaches to biotechnologies for engineering plants that sequester more carbon in durable soil organic matter either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.
