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.

Future food production may move partly into restaurants, factories, and homes. Regulators must manage contamination, labeling, allergens, waste, and quality without blocking small innovators. 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.

Robocalls and spam calls continue to reach users despite various blocking technologies, partly because scammers can spoof caller information and operate across international boundaries where enforcement is inconsistent. A fully effective, universal solution remains unbuilt.

Organisms survive extreme cold, darkness, and nutrient regimes, but molecular mechanisms are only partly known. Genomic and omics platforms can reveal adaptation strategies.

Chronic fatigue syndrome is diagnosed in women considerably more often than men, and the biological or social reasons behind this imbalance remain only partly understood. A clearer answer could improve diagnosis and treatment for both sexes.

Childhood asthma rates have risen substantially, but why some children develop severe, persistent symptoms while others exposed to similar triggers don't remains only partly understood. A clearer answer could improve both prevention and treatment.

This gut infection frequently returns after treatment, partly because antibiotics disrupt the broader gut microbiome that would normally help prevent it. Better prevention of recurrence remains an unresolved clinical challenge.

Earth's magnetic field protects us from solar radiation, but the dynamo process that generates it deep underground is still only partly understood. This matters for predicting how long that protection will last.

Many social systems implicitly reward productivity with greater respect or resources, yet most ethical traditions insist human worth shouldn't depend on usefulness alone. This unresolved tension underlies debates about disability, aging, and social value.

Bee populations have declined sharply in many regions, partly due to pesticide exposure, threatening the pollination that much of global food production depends on. A farming approach that protects both crops and pollinators remains incomplete.

Diet and exercise advice hasn't solved the obesity epidemic, and the biological reasons weight loss is so hard to sustain remain only partly understood. A deeper understanding could lead to treatments that actually last.
