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.

Robots can now handle many industrial tasks well, but tasks requiring soft, adaptable touch, like handling fabric or fragile objects, remain surprisingly difficult. Closing this dexterity gap would open robotics to far more everyday uses.

Zero-day flaws are unknown weaknesses in software that attackers can exploit before a fix exists, and current detection methods still miss many of them until after damage is done. Finding these flaws proactively remains one of cybersecurity's hardest problems.

Economic growth has not been inclusive enough, leaving large groups in informal, low-paying work without safety nets. Targeted cash transfers and universal basic social protection floors could reduce extreme poverty.

Population shifts toward cities or away from certain regions can leave old district boundaries badly mismatched with current populations, distorting how fairly votes translate into representation. Regularly updating these boundaries fairly remains politically contentious.

Fewer reporters are left covering city councils, local courts, and regional agencies, meaning much of everyday governance now happens with almost no public scrutiny. This local news gap makes accountability at the community level far harder to maintain.
