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.

Some interventions may permanently alter ecosystems, genomes, atmospheric systems, or social institutions. Decision processes must handle uncertainty, dissent, intergenerational justice, and irreversible consequences. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Automation may remove tasks gradually rather than eliminate whole occupations, leaving workers with unstable hours and declining bargaining power. The challenge is designing transition institutions before labor-market weakness becomes entrenched. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

If access to longevity technologies is unequal, societies may face new divisions over wealth, inheritance, authority, and opportunity. Ethical and fiscal systems must prevent extended life from becoming a mechanism for permanent elite control. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Temporary or permanent height exchange for social or economic benefits creates new bodily hierarchies and health risks. The problem is protecting bodily integrity from becoming a tradable commodity linked to status.

The ability to freeze aging in specific organs or features while others continue creates new forms of body modification and potential health imbalance. The problem is ensuring medical safety, informed consent, and equitable access without enabling permanent physical stratification.

Companion drones assigned at birth that cannot be permanently powered down raise questions of autonomy, surveillance, and liability. The challenge is giving individuals genuine authority over devices that have been present since infancy without creating safety gaps.

Statues that continuously change expression or posture according to live public sentiment risk turning monuments into unstable opinion mirrors. The problem is allowing cultural responsiveness without erasing the original historical record or creating permanent contention over every figure.

The ability to permanently remove selected people from one’s sensory field can protect against harm but also enable complete social erasure and polarisation. The challenge is setting limits and accountability so that muting remains a last resort rather than a default social tool.

Spoken words may leave lasting sonic residues audible only to selected listeners, creating hidden layers of communication and potential surveillance. The challenge is controlling persistence, access, and erasure of these echoes so they do not undermine privacy or create invisible social hierarchies.

Infants may receive temporary cognitive or motor skill packages that expire after a trial window, creating pressure to purchase permanent versions. The challenge is ensuring that basic developmental capacities remain freely available and that commercial skill layers do not become gatekeepers of opportunity.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

If sleep becomes a tradable commodity sold in discrete blocks, the poorest citizens may be forced into permanent light or irregular cycles. The challenge is designing access systems that treat restorative sleep as a basic need rather than a market good, while still allowing voluntary exchange for those who choose it.

Rapid language change driven by neural interfaces may make ordinary conversation between grandparents and grandchildren impossible without permanent translation layers. The problem is preserving mutual understanding and cultural continuity without forcing everyone onto the same implant standard or erasing linguistic diversity.

As digital navigation layers become permanent fixtures in daily life, physical landmarks lose meaning and people lose the ability to orient themselves without screens. The challenge is creating systems or practices that preserve spatial awareness and independent wayfinding while still allowing beneficial digital tools. Solutions must work across cultures, age groups, and infrastructure levels, avoid creating new dependencies, and remain usable when networks fail.

Many agricultural and infrastructure systems are designed around historical seasons that may no longer exist. A useful solution must help governments revise calendars, reservoirs, insurance, crops, and public budgets under deep uncertainty. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Maps rarely capture broken lifts, blocked sidewalks, steep surfaces, or staff-dependent access. Community sensing plus uncertainty-aware routing could produce useful guidance while clearly communicating confidence and risk. 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 forecast uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

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.

The way solid-state drives store data internally makes secure, complete deletion technically harder than with traditional spinning hard drives. This creates lingering privacy and security risks when these drives are discarded or resold.
