World Solve

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.

Thousands of victims from past wars and disasters remain unidentified, leaving families without closure decades later. Better, cheaper identification methods could resolve many of these long-standing cases.

Gig work can offer flexibility but often comes with unpredictable income swings that make financial planning difficult for workers. A system that offers more income stability without eliminating flexibility remains unresolved.

Public transit systems that depend heavily on fares often struggle financially, leading to service cuts that push more people toward driving. A more sustainable funding model remains unresolved in many cities.

New, fast-growing markets often attract inexperienced investors right before major price crashes, leading to significant personal financial losses. Protecting newer investors without stifling innovation remains an unresolved balance.

Access to affordable business loans is heavily skewed toward people who already have assets or established credit, locking out many capable entrepreneurs. A fairer lending system remains an unresolved economic gap.

Aid money is sometimes available quickly after a disaster, but reaches affected people slowly due to administrative bottlenecks. Cutting this delay without sacrificing accountability remains a persistent logistical challenge.

Surveillance capabilities often grow quietly, justified by security concerns, with limited public awareness or debate about their true scope. Building lasting oversight mechanisms remains a persistent democratic challenge.

People with more money can typically afford far better legal defense than those without, creating uneven outcomes within the same justice system. Equalizing access to quality legal representation remains a persistent gap in many countries.

People displaced by climate disasters often don't qualify for legal refugee status under current international law, leaving them without clear protection. A modern framework addressing this gap remains unbuilt.

Cryptocurrency regulation varies wildly by country, creating loopholes that enable fraud and money laundering to move freely across borders. A more consistent global approach remains politically difficult to achieve.

As more government services move online, people without reliable internet, often the poorest or most rural, risk being left further behind. Ensuring equal access requires more than just digitizing existing systems.

Chronic fatigue syndrome leaves patients severely limited in daily function, yet its underlying biological cause remains poorly understood and often dismissed. Without a clear cause, effective treatment remains extremely difficult to develop.

Cooling saves lives during extreme heat, but most air conditioners rely on energy sources and refrigerants that contribute to climate change. A low-emission cooling solution accessible to poorer regions remains urgently needed.

Many products marketed as biodegradable still break down into tiny plastic particles that persist in the environment for years. A truly safe, fully compostable packaging material remains elusive at scale.

Raising cattle and other livestock produces a significant share of global methane emissions, yet meat remains a major part of diets worldwide. A lower-emission farming method that doesn't require giving up meat entirely remains unsolved.

Even advanced AI systems sometimes generate plausible-sounding but incorrect answers, and users often can't tell the difference without checking elsewhere. A dependable way to prevent this remains unsolved.

Once deployed, a model could be subtly altered or poisoned without obvious signs, potentially changing its behavior in harmful ways. There's no simple, universal way yet to verify a model is exactly as it was originally trained.

Countless websites, articles, and pages vanish permanently when companies shut down or servers go offline. Without better and more complete web archiving, we risk losing large chunks of internet history.

Billions of people still lack any formal digital identity, cutting them off from banking, healthcare, and government services. A decentralized system could include everyone without handing control to one entity.
