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.

Every search so far has come back empty, but our tools for detecting distant life are still crude. Knowing the answer would reshape biology, philosophy, and how we think about our place in the universe.

Achieving protocols for equitable and rapid distribution of medical countermeasures in pandemics at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Current approaches to urban hydrogen distribution leak sensor and isolation meshes 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.

A persistent gap exists in realizing practical, scalable solutions for distributed methane leak detection and auto-mitigation systems. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.
