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.

The first hours after a disaster are often the most critical for saving lives, yet aid frequently takes days to arrive due to logistics and coordination failures. Closing this gap could save many lives that are currently lost to delay alone.

Kids today are developing weight-related health problems that used to appear mostly in adults, and this trend is accelerating globally. Solving it needs more than individual willpower, it needs changes to food systems and environments.

The absence of robust, context-adapted solutions for earth-abundant multi-day energy storage chemistries creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Current approaches to designs for energy systems that remain functional during multi-day extreme weather events either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Despite recognition of its importance, reliable methods for platform technologies for 30-day zoonotic antiviral response are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
