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.

3D-printing complex structural metal components in microgravity often results in porosity and micro-cracks. We need reliable thermal controls and melt-pool monitoring for zero-g metal and composite fabrication.

ZBLAN optical fibers produced in space exhibit far lower light attenuation than Earth-made fibers, but manufacturing defect rates remain high. Microgravity fluid dynamics and draw-tower controls must be perfected.

Infections like Zika or cytomegalovirus can cause serious birth defects if contracted during pregnancy, and prevention options remain limited in many regions. Better vaccines or protective treatments remain needed to close this gap.
