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.

Even with extensive automated testing, software products regularly ship with bugs that only appear once real users start interacting with them in unpredictable ways. Comprehensive, fully reliable bug detection before release remains an unsolved engineering challenge.

Many websites and applications are still built without full consideration for users who rely on screen readers, alternative input devices, or other accessibility tools. Making accessibility a foundational design principle rather than a later patch remains inconsistent.

Tools designed to detect AI-written assignments frequently produce false positives, wrongly flagging legitimate student work as AI-generated. This unreliability creates real consequences for students while genuine cheating sometimes slips through undetected.

Fake reviews generated at scale by AI can be nearly indistinguishable from genuine customer feedback, undermining trust in online shopping decisions. Detection tools are struggling to keep pace with how convincing these fakes have become.

AI health tools can sometimes provide advice that sounds plausible but is subtly wrong or dangerous, and there's no consistent, scalable system for catching these errors before they reach real patients. This gap grows more urgent as AI health tools become more widely used.

A few seconds of someone's voice is now enough to generate convincing fake audio of them saying anything, and current detection tools often fail to catch high-quality fakes in real time. This is already being used for financial scams targeting families and businesses.

Ageing populations, urban diets, and pollution will drive surges in cardiovascular disease, diabetes, cancer, and chronic respiratory conditions. Scalable chronic-care models, digital coaching tools, and preventive policy reforms are needed.

By 2040, editing tools and gene drives could reshape ecosystems or be misused to create dangerous pathogens. Governance frameworks, secure design pipelines, and ethics review infrastructures are needed.

Uncertainties in ice dynamics, bedrock conditions, and ocean–ice interactions make it hard to forecast tipping points and metres of future sea-level rise. Better grounding-zone measurements and data-assimilation tools could sharpen projections.
