World Solve

Diagnosing Alzheimer's currently often requires expensive brain imaging or invasive procedures, limiting how widely early detection can be used. A cheap, accessible blood test could change how early treatment can begin.

Many people with chronic insomnia end up relying on sleep medication for years, since non-drug treatments don't work consistently for everyone. A more effective, sustainable solution remains an open need.

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.

Chronic sinus inflammation affects a large number of people and current treatments, from medication to surgery, often only partially resolve symptoms long-term. A more definitive treatment remains undeveloped.

Age-related muscle loss, known as sarcopenia, contributes to frailty and falls in older adults, and current treatments rely mainly on exercise and diet rather than addressing the underlying biological decline. A more direct medical solution remains undeveloped.

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.

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.

The constant ringing or buzzing sound of tinnitus affects millions of people, and current treatments mostly help patients cope rather than eliminate the underlying cause. A real cure remains undiscovered.

Pancreatic cancer often shows no clear symptoms until it has already spread, making it one of the deadliest common cancers. An affordable early screening method could dramatically improve survival rates.

A country can be found in violation of international law and simply ignore the ruling with little real consequence, especially if it holds significant economic or military power. This selectively weakens the rule of law based on who is being judged.

New technologies have always displaced some jobs while creating others, but there's no agreed threshold for how much short-term harm is an acceptable cost of long-term progress.

A small number of large companies control a significant share of the world's seed and agricultural input supply, raising concerns about farmer dependency and pricing power. More diverse, resilient supply structures remain underdeveloped.

False information about disaster response, shelters, or aid can spread rapidly during emergencies, sometimes putting lives at further risk. Faster, trusted communication channels during crises remain underdeveloped in many regions.

Antibiotics are widely used in livestock farming to prevent disease and promote growth, contributing significantly to antibiotic resistance in humans. Reducing this use without harming farmers' livelihoods remains a persistent unresolved challenge.

Fertilizer runoff from farms feeds harmful algae blooms in nearby lakes, damaging drinking water and local ecosystems. Preventing this at the source remains cheaper than treating it after the fact, but adoption is still limited.

Microplastics have been found nearly everywhere scientists have looked, including soil and tap water, yet no affordable removal method exists at scale. This leaves an existing, growing contamination problem largely unaddressed.

Overgrazing and development have degraded vast grassland ecosystems worldwide, and restoration efforts remain small compared to the scale of the damage. A more scalable restoration method could recover important habitat and carbon storage.

Data centers powering cloud services consume enormous amounts of electricity and water for cooling, and demand keeps climbing with AI adoption. A genuinely sustainable path for this growth remains unresolved.

Evidence suggests Mars once had liquid water, a key ingredient for life, but no mission has yet found conclusive proof of past or present microbes. Answering this remains one of planetary science's biggest open questions.

Precious samples brought back from the Moon or asteroids need to remain scientifically useful for generations of future researchers. Long-term sample preservation technology hasn't fully caught up with mission ambitions.
