Millions of pre-trial detainees languish in overcrowded prisons for years due to acute judicial vacancy rates and outdated paper-based case management.

This disfiguring and disabling condition continues to affect millions in tropical regions, and while some treatments exist, access remains inconsistent and the underlying infection prevention needs further improvement. Closing this gap remains an ongoing global health priority.

This parasitic disease affects millions in tropical and subtropical regions, but effective treatment remains expensive, difficult to access, or logistically challenging for many affected communities. Closing this access gap remains unresolved.

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.

COPD gradually reduces lung function over years, and while treatment can ease symptoms and slow decline, it can't reverse the underlying lung damage. A cure remains out of reach for the millions living with this condition.

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.

Millions of people experience debilitating, unpredictable migraines that current treatments only partially control, and the underlying biological triggers remain incompletely understood. More precise treatment based on individual causes remains out of reach.

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.

Millions of people live with persistent, disabling fatigue that doctors struggle to diagnose clearly or treat effectively. The underlying biology remains poorly understood despite decades of patient reports.

People without citizenship often can't access healthcare, education, legal employment, or travel documents, trapping them in a kind of legal limbo. Resolving statelessness requires cooperation between countries that often have little incentive to act.

Air pollution contributes to respiratory and cardiovascular disease in millions of people living in polluted urban areas, and treatment only addresses symptoms, not exposure. Reducing the exposure itself remains the harder, unresolved half of the problem.

Migrant workers often pay steep fees to send money to family in their home countries, cutting into wages that are frequently already low. Cheaper remittance systems could meaningfully improve financial security for millions of families.

Heart muscle doesn't regenerate well once damaged, often leaving survivors with permanently reduced heart function. Finding a way to regrow healthy heart tissue could transform recovery for millions of survivors.

Data breaches exposing millions of passwords happen with striking regularity, despite widespread awareness of the problem. A more fundamentally secure approach to authentication is still needed.

Millions of applications depend on open-source code maintained by volunteers, and a single hidden change can spread unnoticed to countless systems. A trustworthy verification system remains a major unsolved need.

Cosmic radiation gradually damages electronics, and there's no way to send a repair technician to fix something millions of miles away. More radiation-hardy systems are essential for missions lasting a decade or more.

Many major rivers depend on glacial melt for a steady water supply, and as these glaciers shrink, the long-term water security of downstream populations becomes increasingly uncertain. Protecting or planning around this shrinking resource remains unresolved.

River deltas provide fertile land for millions of people but are increasingly eroding due to upstream dam construction and rising sea levels reducing natural sediment replenishment. Protecting these critical, densely populated areas remains an unresolved challenge.

Millions of people now earn a living through app-based gig work without the healthcare, sick leave, or retirement benefits traditional jobs offer. Extending fair protections to this growing workforce remains largely unresolved.

False information often reaches millions of people before any correction catches up, and by then the damage to public understanding is already done. Fixing this gap is critical to informed public debate.
