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.

Vehicles that dynamically alter destinations according to collective emotional signals create unpredictability for both passengers and city logistics. The challenge is balancing responsiveness with reliability so that mobility remains dependable for work, care, and emergency needs.

Vendors operate with thin margins and little historical data. Lightweight forecasting, shared cold storage, and cooperative purchasing could convert neighborhood-level signals into practical decisions without requiring enterprise software. 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.

Fabricated reviewer identities, complete with fake credentials, have occasionally been used to manipulate the peer review process in favor of certain papers. Verifying reviewer authenticity more rigorously remains an unresolved challenge for academic publishing.

Aggressive scraping bots, including those collecting data to train AI models, can overload smaller websites not built to handle that volume of automated traffic. Balancing open web access with protection against this kind of strain remains unresolved.

Once login credentials are leaked in a breach, they often remain accessible and exploitable for attackers on illicit marketplaces for years afterward, long after the original breach was reported. Meaningfully reducing this lingering exposure remains unresolved.

Many connected devices become permanently vulnerable once their manufacturer stops issuing security updates, yet the devices often remain in active use for years afterward. A sustainable way to keep abandoned devices secure remains unresolved.
