World Solve

Some infants experience repeated, severe respiratory infections in their first years of life despite preventive measures, and current understanding of why this happens in certain babies remains incomplete. Better prevention for this vulnerable group remains needed.

Extended antibiotic use can disrupt gut bacteria in ways that cause lasting digestive problems for some patients, even after the antibiotics are no longer needed. Better protection of the gut microbiome during necessary antibiotic treatment remains undeveloped.

Persistent dizziness linked to inner ear problems can be difficult to diagnose precisely and treat effectively, leaving many patients with ongoing symptoms. A more reliable, targeted treatment approach remains undeveloped.

A minor injury sometimes triggers long-lasting chronic pain in some patients while similar injuries fully resolve in others, and the biological reason for this difference isn't fully understood. Solving this could improve treatment for a wide range of chronic pain conditions.

Many parts of the world have extremely few mental health professionals relative to their population, leaving most people with mental health needs entirely unsupported. Solving this requires new models of care delivery, not just more funding.

A persistent gap exists in realizing practical, scalable solutions for technologies for the safe and efficient long-term storage of renewable energy at seasonal scales. 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.

Stomach cancer often causes no clear symptoms until it has progressed significantly, particularly in regions without routine screening programs. Earlier, more accessible detection could substantially improve survival outcomes.

Thousands of patients remain on transplant waiting lists that never resolve in time, largely because donor organ supply can't keep pace with demand. Alternatives like lab-grown organs remain the most promising but still unrealized solution.

Diabetic retinopathy remains a leading cause of blindness among working-age adults, and while treatment can slow progression, prevention before damage begins remains incomplete. Earlier, more effective prevention could protect vision for millions of diabetics.

Highly effective hepatitis C treatments exist, but cost and healthcare access still prevent many infected people worldwide from receiving them. Expanding affordable access remains the primary barrier rather than the science itself.

Lower back pain is one of the most common causes of disability worldwide, yet treatment for chronic cases still mostly focuses on symptom management rather than fixing underlying structural or nerve issues. A more definitive solution remains elusive.

Effective treatments for hepatitis B exist, but cost and access remain out of reach for many of the hundreds of millions of people living with the infection globally, particularly in lower-income regions. Closing this access gap remains unresolved.

Bone density loss often goes unnoticed until a fall causes a serious fracture, by which point significant damage has already occurred. Better early detection and prevention could avoid many of these life-altering injuries.

Drug-resistant tuberculosis requires longer, more expensive, and more toxic treatment regimens that many patients in affected regions simply can't access or complete. This keeps a preventable disease deadly in the parts of the world least equipped to fight it.

Severe bleeding after childbirth remains one of the leading causes of maternal death worldwide, disproportionately in regions lacking access to blood transfusions and advanced medical care. Affordable, effective solutions for these settings remain limited.

IBS causes chronic digestive discomfort for a significant portion of people worldwide, yet treatment options remain limited to symptom management rather than addressing root causes. The underlying biology is still not fully mapped out.

Emerging gene therapies show promise but remain extremely expensive and inaccessible to the vast majority of people living with sickle cell disease worldwide, especially in Africa where it's most common. Making a real cure affordable and available remains unsolved.

Conflict of interest rules exist in many places but are inconsistently enforced, letting officials benefit financially from decisions they themselves make. Stronger, consistently enforced rules remain missing in a large share of governments worldwide.

Some countries publish detailed defense budgets while others keep most military spending secret, making it hard to assess true security risks or hold leaders accountable for spending choices. Greater transparency remains politically resisted in many places.

Even when an agency is widely recognized as ineffective or wasteful, political and legal hurdles can keep it running largely unchanged for years. Faster institutional accountability mechanisms remain rare in most government systems.
