World Solve

AI models trained on real-world data often absorb and sometimes amplify existing societal biases, and current bias correction methods only partially address the problem. A more complete solution remains an active and unresolved area of research.

Medical brain drain to Europe and the Gulf worsens staff shortages, especially in rural clinics. Task-shifting to trained community health workers and telemedicine could partially offset shortages.

Mars (0.38g) and the Moon (0.16g) have partial gravity levels whose long-term impact on embryo development is completely unknown. Ground-based and orbital partial-gravity mammalian centrifuges are required.

Older adults with weakened immune systems remain at ongoing risk of repeated pneumonia infections despite vaccination and preventive care, and current prevention strategies only partially reduce this risk. A more effective, targeted approach remains needed.

Hormonal changes after menopause accelerate bone loss, increasing fracture risk, and current prevention methods only partially offset this decline. A more effective, targeted prevention approach remains needed.

The vast majority of autoimmune disease diagnoses occur in women, and the biological reasons behind this imbalance remain only partially understood. A clearer answer could open new treatment approaches for both sexes.

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.

Fertility treatments like IVF help many people conceive, but success rates still drop significantly with age due to biological factors that current medicine can't fully reverse. Understanding and addressing this decline remains incomplete.

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.

When judges' careers, safety, or institutional funding depend on staying in the government's good graces, their ability to rule impartially against powerful officials can be compromised. Protecting judicial independence from this kind of pressure remains an ongoing struggle.

Regulators sometimes come from, or later move into, the very industries they oversee, raising ongoing concerns about impartiality. Structural solutions to this revolving door problem remain inconsistently applied.

A meaningful share of people who contracted COVID-19 continue experiencing fatigue, brain fog, or other symptoms long after recovery, with no reliably effective treatment yet available. This remains a significant and only partially understood health burden.

Food allergy rates have been rising for decades, and the exact reasons behind this trend remain only partially understood. Understanding the cause could help prevent, not just manage, this growing health issue.

A small number of people show natural resistance to certain infections or conditions, and understanding why could reveal entirely new treatment approaches. This resistance remains only partially understood at a genetic level.

This is the famous Halting Problem, proven impossible to solve in full generality, yet many partial and practical questions around predicting program behavior remain actively studied. This shapes the theoretical limits of what computers can ever determine about themselves.

Related conjectures about how primes combine remain only partially proven for specific ranges, without a fully general confirmed pattern. This connects to broader unresolved questions about the additive structure of prime numbers.

Partition numbers grow in a complex, only partially understood way, and while excellent approximations exist, a complete exact predictive formula for all cases remains elusive. This continues to be an active area within combinatorics and number theory.

Graph theory offers many partial answers about guaranteed patterns within large networks, but a fully general and complete theory covering every possible network structure remains incomplete. This affects our understanding of everything from social networks to biological systems.

Combinatorial geometry problems like this remain partially solved for specific shapes and configurations, but a fully general guarantee across all possible line arrangements is still unproven. This connects visual intuition with rigorous mathematical guarantees.

Various conjectures link the number of prime factors a number has to specific patterns of behavior, but many of these connections remain only partially proven. This continues to be explored within analytic number theory.
