World Solve

Turning seawater into drinking water is technically possible but still too energy-intensive and expensive for many water-scarce regions. Cheaper desalination could solve water shortages for millions of people.

Neuroscience can map which brain regions activate during thought, but nobody can explain why that activity produces subjective experience at all. This gap separates our understanding of the brain from any real understanding of the mind.

Students in low-connectivity regions of Global cannot benefit from most digital learning platforms, which assume continuous internet access unavailable in their communities.

A persistent gap exists in realizing practical, scalable solutions for solutions for providing reliable and affordable internet access in rural and remote regions. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

Stunting rates in parts of Mexico remain high despite food aid programs, because interventions rarely address the underlying combination of dietary diversity, sanitation, and maternal nutrition simultaneously.

A persistent gap exists in realizing practical, scalable solutions for protocols for the ethical conduct of research involving vulnerable populations in climate-affected regions. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

Despite recognition of its importance, reliable methods for solutions for providing high-quality primary healthcare in remote and underserved regions 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.

The absence of robust, context-adapted solutions for solutions for providing safe drinking water in regions with high natural or anthropogenic contamination 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.

Achieving pathways for transitioning fossil-fuel dependent regions to diversified economies at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Create scalable combinations of eDNA, acoustic sensing, imaging, community science, and AI that produce trustworthy species data in under-surveyed ecosystems.

Develop standards, tracking, community oversight, vehicle financing, and safe-route models for children traveling through informal transport networks.

Develop modular panels, controllers, batteries, training, spare-parts supply, and warranties so off-grid solar systems remain functional beyond initial installation.

Develop diagnostics, certification, modular design, and business models for second-life batteries without creating fire hazards or shifting disposal burdens to poorer regions.

Develop low-cost ways to map and manage rising soil salinity before farms become economically unviable due to over-irrigation, seawater intrusion, or poor drainage.

Develop scalable rehabilitation systems that combine community workers, telemedicine, low-cost devices, and culturally appropriate exercises for stroke survivors far from specialists.

Develop point-of-care diagnostics for invasive and drug-resistant fungal infections, especially among immunocompromised patients in regions lacking advanced laboratories.

Governments and households in disaster-prone regions of India lack pre-arranged financing mechanisms, forcing reliance on slow post-disaster aid appeals rather than rapid, budgeted recovery funds.

Achieving affordable and durable solutions for household air pollution in biomass-dependent regions at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Postpartum hemorrhage remains a leading cause of maternal death in Indonesia because low-resource facilities often lack rapid blood-typing, stored blood products, and trained staff to intervene within the critical first hour after delivery.

The absence of robust, context-adapted solutions for solutions for providing reliable electricity to health facilities in off-grid regions 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.
