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.

Brazil, South America
Competence is often real but invisible to employers because certificates measure course completion rather than performance. Practical assessments, portable evidence, and trusted local validators could improve matching without forcing workers into expensive retraining. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with allocate uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Small teams frequently lack stable repositories, metadata discipline, and affordable compute for preservation. Incentives for reproducible packaging, federated archives, and low-cost reruns could strengthen the reliability of applied science. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with verify uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Purchased or AI-generated fake followers and engagement can make an account appear far more influential or trustworthy than it actually is, misleading both audiences and advertisers. Reliable detection and removal of this fake activity remains inconsistently enforced.

Scammers can quickly generate convincing fake charity campaigns using AI-created images and stories, especially in the aftermath of real disasters, diverting donations away from legitimate relief efforts. Verifying legitimacy quickly enough remains an unresolved challenge for donation platforms.

Even advanced AI systems can confidently state things that violate obvious physical logic, like objects falling upward or liquids not filling containers. This gap shows current AI still lacks a genuine model of how the physical world works.

Europe must support Ukraine while rebuilding its own defence posture and replacing Russian energy imports, all under fiscal and political constraints. Defence-industrial coordination platforms and grid-optimization tools are key areas for innovation.

Cosmological data show the Universe’s expansion speeding up, yet we lack a clear physical mechanism beyond a simple cosmological constant. Precision surveys and alternative gravity theories could clarify whether dark energy is a new field or modified gravity.
